Science and technology are the key driving forces for promoting productivity progress. The original intention and fundamental goal of the emergence and development of science and technology is to continuously improve and optimize the environment for the production, life, and development of the public, providing a material and spiritual foundation for human society to move towards a higher form of civilized society. The development of science and technology is closely linked to the enhancement of social public interests. If we overly focus on the economic efficiency of science and technology and neglect its social efficiency, science and technology will inevitably deviate from its original intention of emergence and development, and become a tool for capital to pursue efficiency. Dealing with the efficiency relationship between science and technology at the micro and macro levels, grasping the rhythm of scientific and technological innovation and progress, is conducive to helping us walk out of the Western style scientific and technological innovation and development path of “capital replacing labor”, and returning scientific and technological innovation and development to the original path of “people-oriented”. Only when scientific and technological innovation and progress are highly consistent with the public interest can science and technology reflect its due social value, avoiding it ultimately becoming a value tool for private capital to pursue profits.

We are used to thinking of the ocean as infinite, but it is finite. Human beings have violated science and discharged pollutants into the ocean over the years, damaging both the Marine ecosystem and the common well-being of mankind. They pose a serious threat to human existence and development. When exploring and reflecting on the root of these ecological environment problems, people will turn their eyes to human centrism one way or another. Nowadays, the traditional human centrism is difficult to get out of the old development dilemma on the relationship between man and nature. Therefore, in order to solve the “coexistence dilemma” of human beings, we must establish a scientific and reasonable principle of subjectivity, that is, to establish “modern human centrism”. His existence, is fully aware of the current human for the destruction of the environment brought about by the extreme confusion. It is contemporary people who see this ecological dilemma in the ocean, so they want to find ways to present or solve the problem. At this time, the emergence of public art gives problems a chance to buffer.

Rural planning is to make the countryside neat and tidy through planning, including farmland planning and sewage discharge planning. All individual buildings shall not be built outside the planned area or the construction land at will, and shall not be built in the demolition area with incomplete infrastructure. The planning and construction of pits and ponds shall be implemented to control agricultural pollution. The overall deployment of long-term social, economic, scientific and technological development is the basic basis for guiding rural development and construction.

In the past forty years, the development of Chinese scenic design has been influenced by many forms of scenography from around the world. As time has progressed, numerous plays have reflected Chinese scenic designers’ tendency to actively search for visual themes from traditional Chinese culture that suit contemporary aesthetic standards. In the process of this search, Chinese traditional culture has been restructured for application in contemporary scenic design. Questions regarding how scenic designers should, with originality, inherit and transform Chinese traditional culture within a contemporary aesthetic context and, within that process, how they should apply new theatre technologies, have come to the fore. The most representative works of Chinese scenic designers in the past decade often embody traditional Chinese aesthetics and temperaments in very expressive ways. Transforming the conceptual beauty of traditional Chinese culture into contemporary forms in scenic design, they are clearly influenced by Chinese aesthetics and philosophy.

Ceramic membrane has made rapid progress in industrial/municipal wastewater treatment and drinking water treatment owing to its advantageous properties over conventional polymeric membrane. The ceramic membrane processes are a rapidly emerging technology for water treatment, yet virtually no information on the performance and fouling mechanisms diatomite ceramic membrane. In this study, filtration experiments were carried out using a mixture of humic acid and kaolin which simulated surface water under constant pressure to reveal fouling characteristics of the filtration of the diatomite ceramic membrane. The results showed that the removal rate of VU254 was 52%~70%, and turbidity was 90%~95% when treat mixed water of 5-10mg/L kaolin and humic acid. And membrane surface retention and membrane pore adsorption were the mainly removal routes. And the flux slowly decreases, rapidly decreases, gradually decreases and stabilizes were three processes of diatomite ceramic membrane fouling. And the first and third stages of membrane fouling mainly caused by complete blocking, and the second stage was mainly controlled by standard blocking. The study found that humic acid would cause both the pore blocking and the fouling of the membrane surface when turbidity was present, especially the membrane surface pollution, it was the major factor of diatomite ceramic membrane fouling.

In the era of intelligent economy, scientific and technological talents have become the key objects of staff incentives in high-tech industries, but the actual effect of scientific and technological talents incentive is not optimistic, mainly manifested in the generally low incentive satisfaction of scientific and technological talents. The main reason for the above problems is that the incentive mechanism of scientific and technological talents in high-tech industry is not reasonable. In view of the problems existing in the incentive mechanism of scientific and technological talents, a new incentive mechanism of scientific and technological talents is constructed by integrating the ideas and methods of human capital theory, behavioral science and incentive theory. Combining the value-added of financial capital of high-tech enterprises with the ability, contribution, behavior and effort of scientific and technological talents, we can fundamentally stimulate the enthusiasm, initiative and creativity of scientific and technological talents.

This paper studies the endogenous relationship between innovation investment and enterprise performance through the three-stage least square method, taking the companies listed on the Main board of A-shares in Shanghai and Shenzhen stock Exchanges from 2014 to 2018 as research samples, and explores whether the improvement of management ability can effectively promote the transformation of enterprise innovation investment into enterprise performance from the perspective of innovation. The research results show that there is a two-way influence between innovation input and enterprise performance. The innovation input can significantly promote the growth of enterprise performance, but its promotion effect is relatively lagged. The growth of performance may weaken the enterprise's innovation motivation and reduce the future innovation input. Management competence has a significant positive moderating effect on the relationship between innovation input and performance. This paper provides an important reference for balancing innovation and enterprise performance and improving the transformation efficiency of enterprise innovation investment to increase enterprise value.

Normally, the cost stickiness in enterprises further reduces the efficiency of asset allocation and the accuracy of earnings decision, thus aggravating the risk taking. This paper takes Chinese A-share listed companies from 2009 to 2019 as samples to empirically test the impact of cost stickiness on enterprise risk and the moderating effect of long-term incentive mechanism on this impact. The results show that cost stickiness increases corporate risk significantly. Management shareholding further aggravates the impact of cost stickiness on corporate risk. After further analysis, it is found that cost stickiness significantly increases corporate investment risk, meanwhile, cost anti-stickiness also significantly increases corporate risk, and management shareholding also aggravates the impact of cost anti-stickiness. This study further expands the research on the economic consequences of cost stickiness, also provides new ideas for enterprises to control the level of management shareholding to further restrain the degree of cost stickiness.

Many deflected fault zones exist under the dam foundation Xiang-jiaba Hydropower Station in southwestern China. Clastic rock is the main medium with poor physical and mechanical properties. In or-der to study the creep properties of the clastic rock, triaxial compression creep experiments were carried out on a rock servo-controlling rheology testing machine. From the test results, it can be concluded that the clastic rock has obvious creep characteristics, and the time-dependent deformation is large. Based on the test results, the relationship between axial strain and time under different confining pressures is studied. The relationship between axial strain rates and deviatoric stress under different stress levels is also discussed in de-tail. Furthermore, the creep failure mechanism under different confining pressures is analyzed as well. Therefore, the creep law of the clastic rock specimen is gained. The relationship between the Burgers creep model and its parameters is obtained by fitting the creep curve with Burgers creep model. The result shows that Burgers model can accurately describe the creep properties of the clastic rock in Xiang-jiaba Hydro-power Project.

For 3D geological modelling of oil and gas reservoirs, well pattern density is directly related to the number of samples involved in the calculation, which determines the variation function of stochastic modelling and has great impacts on the results of reservoir modelling. This paper focuses on the relationship between well pattern density and the variogram of stochastic modelling, selects the large Sulige gas field with many well pattern types as the research object, and establishes a variogram database of stochastic models for different well pattern densities. First, the well pattern in the study area is divided into three different types (well patterns A, B, and C) according to well and row space. Several different small blocks (model samples) are selected from each type of well pattern to establish the model, and their reasonable variogram values (major range, minor range and vertical range) are obtained. Then, the variogram values of all model samples with similar well pattern densities are analysed and counted, and the variogram database corresponding to each type of well pattern is established. Finally, the statistical results are applied to the modelling process of other blocks with similar well pattern density to test their accuracy. The results show that the reservoir model established by using the variation function provided in this paper agrees well with the actual geological conditions and that the random model has a high degree of convergence. This database has high adaptability, and the model established is reliable.

The actual situation of promoting the reform of curriculum construction with the subject competition to improve students’ innovative ability in practice varies in different universities and disciplines. This paper takes the computer science of Fuyang Normal University as an example to study how the subject competition promotes students’ innovative ability in practice and their comprehensive quality as well.

Objective: To objectively evaluate the clinical efficacy of Longchai Formula Granule (LCFG) on chronic hepatitis B (CHB). Methods: According to GCP, 100 CHB patients who meet enter criterion were encoded and divided randomly into the test group (50 cases) and the control group (50 cases). The patients in test group were treated with LCFG and matrine capsule simulation agent, the patients in control group was treated with matrine capsule and LCFG simulation agent. Both groups have 12-week treatment period. The changes of Chinese medicine symptoms, ALT, AST, graduation of liver function, HBeAg, HBsAg, HBVDNA in CHB patients were observed and compared. Results: After unblinding, statistical data showed that there were 82 effective actual CHB cases composed of 40 CHB patients in test group (10 cases dropout) and 42 CHB patients in control group (8 cases dropout). The total efficient of Chinese symptoms improvement and ALT in test group is better than the control group (P0.05). As a whole, it shows a tendency that the change of these values in test group induced by LCFG is better than these values in control group induced by matrine capsule. Conclusions: In summary, LCFG is effective for CHB patients and has no significant difference with matrine cpasules. However, LCFG is better than matrine capsule in the improvement of symptomatology and liver function.

Steel is a kind of ferromagnetic material, which is extensively applied in such fields as buildings, bridges, railways, machines and lifeline engineering etc. Those engineering structures built of constructional steel will unavoidably experience some damages during their service lifetime, thus which will influence the distribution regularity of internal forces in structures, result in over-stresses, cause the local failure of structures, and even lead to collapse of the whole structure. Therefore, it is a pressing topic to study how to directly evaluate the real-time stressed states of structural members, damages and steel characteristics in present structural health monitoring and diagnosing fields. And the achievements of this research will be of theoretical significance and of application value of engineering.
