This paper introduces a ease of designing experiment in the course of “College Physics Experiment”, which happens in a non-key university. A new method of sound velocity measurement is obtained by analyzing the anomalous phenomena in the designing experiment “Determination of Intrinsic Frequency of Water Beakers”. The students proved that high-end instruments and genius experimenters are not necessarily required in designing experiments. The ordinary instruments under limited conditions and constantly improving experiment schemes could lead to perform well, and general universities, ordinary equipment, non-key institutions, ordinary students can also do well. General institutions can develop designing experiments considering actual conditions to stimulate students’ interest in science research and innovation, and to enhance their sense of self-confidence and accomplishment so as to improve the comprehensive quality.

In this paper, a method was established to measure the oxygen content in titanium metal containing high hydrogen content based on the inert gas fusion and infrared absorption method. Most of the hydrogen could be released in advance at a low temperature in a step-by-step heating mode, and the generation of methane at high temperatures could be avoided. The analytical parameters were optimized, the optimally analytical power is 4. 8 kW in high temperature step, sample weight is 0. 04 - 0. 08 g, fluxes are the combination of capsule nickel and nibbled nickel, minimum analysis time for oxygen is 140 s, and a comparator level is 1 % . A calibration curve was built by using certified titanium standard sample (502-879 ) with a regression equation of y = 0.712 385x. To verify the feasibility of the proposed method, a parallel test was carried out on a Ti64 sample with high hydrogen, and the oxygen recovery of standard addition was also determined on a titanium sample with high hydrogen. The relative standard deviation ( RSD ) was 2.57% , and the recovery of standard addition of the method was between 95% and 107%. These show that the proposed method could accurately determine the oxygen content in titanium containing high hydrogen. [ABSTRACT FROM AUTHOR]

In this paper, we theoretically obtain the relationship between the signal-to-noise ratio of correlated imaging and the number of frames, the target object size, the speckle size by using randomly modulated light. The probability density function of modulated light herein is Rayleigh distribution. Then we experimentally achieve the correlated image of a reflective object (object size is 0.14 m x0.07 m) through intensity fluctuation correlation measurement by a digital light projector which is controlled by a computer to generate randomly modulated light. According to experimental data, the signal-to-noise of correlated image is calculated to be about 1.84, which is in good agreement with the theoretical analysis. This result could be useful to analyze the factor influencing the quality of correlated imaging and promote the corresponding application in long-distance imaging such remote sensing.

This paper firstly analyzes the importance and urgency of establishing open experiment platform to culture qualified people, who have independent thinking ability, practical ability, innovation ability and entrepreneurial ability. This paper discussed the effective ways, such as the club activities, research topics, social needs, interests ami conventional rolling project, etc. , and by these ways, to promote college students to take part in experimental practice. There are some proposals to help open laboratory play a role in practical teaching. The results of the study, not only can fully exert the resource advantage of the open laboratory, but also can provide theoretical support for college students participating in various experimental practice in the new period.

CDIO is a brand-new education idea and implementation system of focusing on students’ practical ability in engineering, and is very efficient engineering education mode in promoting engineer ability. Based on the CDIO engineering education model and combined with the practical teaching of mechanical innovation design and practice course, integrating innovation education and professional education, building practice teaching system combining inside and outside classes were explored. The practice teaching system of combining theory teaching with innovation practices, combining in-class experiments with out-class practices is made in the paper. Theory teaching mainly includes the principle and technique of innovation, scheme innovative design, organization and structure innovative design, innovation design simulation and innovation instance, which focuses on the training of thinking ability, design ability and learning ability. Innovation practice module is comprised of in-class experiments and out-class practices, which focuses on the training of practical ability and engineering ability. Practice teaching contents, teaching methods and examination system are also made in the paper, which provides reference for teaching reformation of relevant subjects. [ABSTRACT FROM AUTHOR]

The traditional experimental teaching methods have not kept pace with the rapid development of the network technology, so experimental mode innovation is very important for training of innovating talents in computer specialty. The paper designed and realized an open 020 experimental teaching system. The integration of reality with virtual in experimental teaching circumstances enables students to fully implement the learning and teaching activities both online and offline. Then, this paper suggests a new V-learning mode based on the study on students’ learning and cognitive stage. Test results at the course of computer network show that the combination of open 020 experimental teaching system and V-learning mode provide a new pattern for developing skills of our students, including professional ability, innovation ability and comprehensive quality. The new mode significantly improves students’ innovation ability and it may be useful possibly for colleges and universities to cultivate more and more excellent innovation talents.

Combined with the construction of provincial experimental teaching demonstration center in Boda College of Jilin Normal University, the paper expounds the experimental teaching reform in the new normal experimental centers of private colleges and universities, highlights the characteristics of local colleges and universities. Based on regional economic and social demands of employment oriented construction and zero docking between students'future jobs and teaching mode the paper deals with the full realization of college talent “culture” and “social business development”. To further strengthen the cultivation of students'practical ability, strengthen the application of skills training, the importance of “artisan spirit” in the practice of enterprise management teaching is fully affirmed to promote its heritage. The development path of the center is put forward and the principle of “one main line, two goals, three-dimensional examination and four combination construction characteristics” is summed up. These achievements may be useful for the relevant universities and provincial experimental teaching demonstration centers. [ABSTRACT FROM AUTHOR]

In order to achieve the goal of the full function of educating people, the modern engineering training has the characteristics of comprehension and innovation. We set the ladder type interdisciplinary integration of modern engineering training, and note to promote gradual innovation ability of students. This paper takes course of (Light Mechanical and Electrical Integration Technology Training" as an example to use divergent thinking k limit thinking training method to train the cognitive innovation of students % to adopt scientific research project to train their comprehensive innovation ; to introduce education thought of (great wisdom" to train the scientific and technological innovation. These methods promote the value of engineering system, students can understand the integration of science and technology and art. This paper can provide a useful reference for otlier universities in teaching reform of engineering training and the cultivation of innovative talents with social responsibility.
