Abstract: The sandwich structure with foldcore is a new type of structural material with light weight, high specific strength, high specific rigidity and multi-functional potential, which is connected with each other in core space, this kind of three dimensional structures can be formed by folding based on two dimensional materials. The main research achievements and characteristics of sandwich structure with foldcore in recent years are summarized and analyzed according to the lightweight and multi-functional requirements of aircraft structure in this paper. The configuration optimization scheme and fabrication process of the sandwich structure with foldcore are described. Moreover, the research status of multi-function of the sandwich structure with foldcore are summarized, including sound insulation, thermal protection, stealth performance of the structure, etc.

Abstract: Concrete filled steel tubular structure is a new type of composite structure, widely used in monolayer or multilayer industrial workshop structure column, frame column, all kinds of equipment support and super high-rise building and bridge structure, connection pipe attracted more research on its theory and experiment at home and abroad on the concrete force has carried on the preliminary summary, analysis of the advantages and disadvantages of concrete filled steel tube of various existing connection mode, and illustrates the current situation of domestic and international research on concrete filled steel tube are connected, and finally puts forward some problems in the study.

Abstract: This paper discusses the progress of lead-zinc mineral processing technology and flotation reagents of China, and proposes that optimize technological process and develop new reagents are the main directions.

Abstract: With the development of mechanics and micro-electronic technology,sensor technology has a great improvement during the 50 years.At the same time,biologic technology is on the march.Biologist put forward more strict demand for biologic sensor,which in same degree boost progress of biologic sensor.This passage try to present basic theory of sensor and some advance biologic sensor.

Abstract: Phenolic alkaloids from Menisphermum dauricum (PAMD) was a compound of multiple fat soluble alkaloid extracted from Rhizoma Menispermi. PAMD had wide pharmacological effects including of anti-arrhythmia, anti-MI, anti-thrombosis, anti-dementia, anti-cancer, anti-inflammatory, inhibiting respiratory depression, influencing on heart electrophysiology, ptotecting heart and nerve after cerebral ischemia, suppressing pain, lowering blood pressure, improving learning disorder and so on.

Abstract: This paper introduced the significance of hot stamping on developing lightweight technology and safety property enhancement in China Automotive industry, as well as the research status and progress and market prospect of hot stamping process, Materials and equipments. Key technology and focus of hot stamping are analyzed, direction of hot stamping further development were proposed. Hot stamping process, technology and equipments with completely independent intellectual property rights were developed surrounding energy saving, process stability, quality consistency, flexible distribution of components’ strength , high cost-effective production and so on, which is of important for development of hot stamping in China.

Abstract: Becoming the second largest carbon market after the EU ETS in the world, China steadily runs the pilot carbon emission trading markets for more than half year. Political and economical context with Chinese Characteristics cultivated a new market from previous EU ETS. Intensive enterprise compliance in June and July witnessed an examination on policy design and implementation. Do the answers test the real performance and satisfy with domestic policy makers, enterprises and the public Anyway, insights from existing pilot markets will be useful for future national market also for other emerging regimes.

Abstract: The international research progress of GaN-based high frequency, high power microwave electronic device is introduced. The latest developments in high efficiency and millimeter wave devices are especially described.

Abstract: Coal Water Slurry (CWS) gasification technology has a stable market due to its technical advantages. China did a lot of research and development work in coal slurry gasification technology, which has made considerable progress. Especially CWS gasification technology with Membrane Water Wall which was put into operation in recent years got a significant improvement in terms of safety, fuel flexibility, reliability and continuous operation cycles.

Abstract: In the large hydraulic concrete structure that conventional nondestructive testing technique can’t implement quantitative detection, using steady Rayleigh wave technique can acquire various characteristic parameters of concrete. The paper introduces the principle and detection system of steady Rayleigh wave technique systematically, and makes detection experiments to introduce steady Rayleigh wave e technique and application progress of it in quality of large hydraulic concrete and nondestructive detection of crack depth. The practice proves that steady Rayleigh wave detection technique has the characteristics of strong antijamming capability and higher detection precision.
