Super-resolution image restoration technique can certainly increase the resolution of the obtained images without altering the system hardware conditions, which has become a research hotspot in the fields of remote sensing, military surveillance, public safety and medical imaging. The spatial domain algorithm has been studied widely and deeply, but it still has shortcomings and limitations. This paper studies the image degradation mechanism, establishes a precise image degradation process model, proposes an improved hybrid MAP-POCS restoration algorithm with using the Huber-Markov random field model as the priori probability model, which adds the convex sets constraints to the MAP estimation process and uses the peak signal to noise ratio (PSNR) to evaluate the recovery image quality. The simulation results show that the improved hybrid algorithm combines the only solution solving feature and noise reduction ability of the MAP method and strong prior knowledge utilized feature and flexibility of the POCS method, effectively ensures the convergence stability of the restoration and maintains the edge details of the restored image, enhances the effect of the super-resolution restoration.

With the development of modern mechanics methods and computer technology, some practical commercial finite element analysis software was introduced to the ultrasonic cleaner design. ANSYS software is a financial structure, fluid, electric field, magnetic field, the sound field analysis in one large general-purpose finite element analysis software can be used in many industrial fields. The basic operation of ANSYS was introduced. The simulation based on the ANSYS was applied in the design of ultrasonic cleaner successfully, which can improve work efficiency and shorten development period of ultrasonic cleaner.

Equipped with type AEM-RS electromagnetic current meter, the buoy provided effective technical platform for on-site rapid monitoring of the ocean current. Performance index and usage in the ocean current buoy of AEM-RS was introduced. Ultrasonic cleaning method in seawater was developed for preventing AEM-RS from biofouling. Ocean current data can serve for oceanographic research and marine resource exploitation.

The growths of AlN and AlGaN materials were carried out in a home-built metal organic chemical vapor deposition (MOCVD) system. The AlN template was characterized by X-ray diffraction (XRD) and it showed the full width at half magnitude (FWHM) of the x-ray (002) scan rocking curve was only 28 arc seconds, while the FWHM of (102) plane was 252 arc seconds. The results suggested a high quality epitaxial material was obtained. Subsequently, an AlGaN-based violet LED was designed on this template by using AlGaN material as the base. The Al composition of electronic blocking layer (EBL) was optimized. By a quick on-wafer electroluminescence (EL) test, it was demonstrated that the output light intensity of the new structure was at least 15% stronger in comparison to that of the traditional GaN-based violet LED. Finally, fully packaged LEDs were fabricated and the luminous power of the new structure was measured by Spherical integrated system. It was confirmed that a 43% increase of the output power can be obtained.

Equipped with type AAQ171 multi parameter water quality sensor, red tide buoy for on-site rapid monitoring of red tide provide effective technical platform. Seven items such as depth, temperature, conductivity, turbidity, chlorophyll, DO and pH are mounted in AAQ171. Performance index and usage in the red tide buoy of each item were introduced. Water quality data can serve for the marine environmental protection and marine resource exploitation.

Shilin tunnel is a separated bi-directional four-lane highway tunnel, and its distinctive geological conditions and fault structure result in frequent geological disaster like large deformation. Construction of tunnels were seriously hampered, and the project was delayed, and the cost increases simultaneously. During construction of Shilin tunnel, accurate forecast of geological condition of surrounding rocks and possibilities of large deformation disaster was done through long distance TSP detection and short distance geological radar detection. Then Effective forecast on large deformation disaster to ensure safety of tunnel construction was carried out through adjusting excavation methods and support parameters, and close monitoring crown settlement, convergence, pressure of surrounding rock and pressure of steel-arch. This way is effective for like large deformation under similar conditions, this successful experience will apply reference for similar projects.

PA/CPP packaging material was used for Chinese steamed bread to evaluate its ability to improve quality and increase steamed bread shelf-life. The changes on the aroma volatiles during storage were assessed using by simultaneous distillation extraction(SDE) with dichloromethane and were analysed by GC-MS. The obtained results showed that there were 17 volatile components in fresh Chinese steamed bread, however, after 3 days of storage at 4°C tempreture, the flavor compounds significant decreased in the steamed bread without packaged, only 6 volatile components could be determinted. For the PA/CPP group storged at 4°C tempreture after 3 days, there were 21 volatile components identified, and most of components were the same to the fresh steamed bread.

The effect of different barrier properties packaging materials (PE, PET, PVC) on the shelf life of the shelled fresh bamboo shoots were studied. The effection of packaging materials were assessed by the sensory evaluation and the changes of their moisture content, ash content, total sugar content and protein content during storage time. The results showed that the shelled bamboo shoots in conditions at 10 °C with the packaging of PVC and PET have the better quality and longer shelf life than which with the packaging of PE and no packaging at the room temperature.

According to electromagnetic waves theories, emissivity modeling of a layered casting surface has been developed to elucidate the different emissivity during the growth of oxide film. Through test detection a angle where p-polarized emissivity assumes a peak value is between 60°-80°. Emissivity stabilized when the growth of oxide film is enough. The conclusion provides an important theory for the design the temperature measurement equipment on the surface of casting.

This paper takes bubbles of bubble shell as research object, mainly studies two bubbles arranged in a vertical position. Applying VOF (volume of fluid) method to simulate interaction between two bubbles, analyses the effect of center distances and diameters on deformation and coalescence of bubbles. Results show that coalescence time of two bubbles with same diameters increases as the center distance increases. To two bubbles with different diameters, when the bigger bubble located beneath at the initial time, the smaller bubble moves upward first and then moves downward before two bubbles coalesce. When the smaller bubble located beneath at the initial time, bubble coalescence cannot happen. This paper is the basis of bubble group research, it is of positive significance to the bubble group research and performance improvement of bubble shell.

This study aimed to explore the influence of intention of Internet use, gender and grade on Internet use, adolescents’ mental health and the relationship between them. 323 middle school students completed the full survey. Results: (a) there was a significant negative correlation between Internet involvement and adolescents’ mental health; (b) for adolescents with different intentions of Internet use and of different genders, Internet involvement, mental health and the relationship between them were different. Conclusions: (a) Internet involvement had negative influence on adolescents’ mental health; (b) intention of Internet use and gender could influence Internet involve- ment, adolescents’ mental health and the relationship between them, while grade had no influence.
