Structural and technological aspects of obtaining and processing functional composite materials based on PTFE(polytetrafluoroethylene)are considered.It is shown that,due to the features of the molecular structure of the matrix polymer,within the framework of the traditional technological paradigm,prerequisites are created for the implementation of a structural paradox,which manifests itself in a decrease in the parameters of the stress-strain and tribological characteristics of composites with an increase in the degree of filling.Within the framework of the concept of multilevel modification,methodological approaches to the implementation of the energy and technological compliance of components,which reduce the negative impact of the structural paradox,are considered. 展开更多

Straw is a general term for the stem and leaf parts of mature crops,and is a multi-purpose renewable biomass energy resource in the agricultural ecosystem.The prospect of comprehensive utilization of straw has become broad with the development of agricultural production,the advancement of science and technology,and the improvement of the level of agricultural mechanization.The comprehensive utilization of straw plays an important role in enhancing the sustainable development ability of agricultural economy and improving the current situation of comprehensive utilization of agricultural resources in my country.This paper briefly combs the development history of straw and the prospect and current situation of comprehensive utilization,and expounds the separation technology of straw components,straw man-made panels,straw concrete,straw returning technology and oyster mushroom cultivation.It focuses on the description of the component separation technology of straw and the manufacturing process of straw-based panels.The different separation methods and separation effects of cellulose,hemicellulose and lignin were introduced in detail,and the static yield strength(MOR),internal bonding strength(IB)and water absorption thickness of several common straw-based panels were compared and studied(TS).Finally,it summarizes the benefit analysis of the comprehensive utilization of straw by scholars from the perspective of economics,and summarizes the corresponding measures based on their own views. 展开更多

Yangtze Estuary Tidal Wetlands Geographic Information System (YETWGIS) is a comprehensive software system for environmental management and decision of Yangtze estuary tidal wetlands. Based on MapObjects components technology, Data Mining technology, mathematical modeling method and Visual Basic language, this software system has many functions such as displaying, editing, querying and searching, spatial statistics and analysis, thematic map compiling, and environmental quality evaluation. This paper firstly outlined the system structure, key techniques, and achieving methods of YETWGIS, and then, described the core modules (the thematic map compiling module and environmental quality evaluation model module) in detail. In addition, based on information entropy model, it thoroughly discussed the methods of environmental quality evaluation and indicators' weight calculation. Finally, by using YETWGIS, this paper analyzed the spatial distribution characteristics of Heavy Metal and Persistent Organic Pollutants (POPs) of the Yangtze estuary tidal wetlands in 2002, and evaluated the environmental quality of the Yangtze estuary tidal wetlands in 2003. 展开更多

We present integrated-optic building blocks and functional photonic devices based on amorphous siliconon-insulator technology. Efficient deep-etched fiber-to-chip grating couplers, low-loss single-mode photonic wire waveguides, and compact power splitters are presented. Based on the sub-μm photonic wires, 2 × 2 Mach–Zehnder interferometers and add/drop microring resonators(MRRs) with low device footprints and high finesse up to 200 were realized and studied. Compact polarization rotators and splitters with ≥10 d B polarization extinction ratio were fabricated for the polarization management on-chip. The tuning and trimming capabilities of the material platform are demonstrated with efficient microheaters and a permanent device trimming method, which enabled the realization of energy-efficient photonic circuits. Wavelength multiplexers in the form of cascaded filter banks and 4 × 4 routers based on MRR switches are presented. Fabrication imperfections were analyzed and permanently corrected by an accurate laser-trimming method, thus enabling eight-channel multiplexers with record low metrics of sub-m W static power consumption and ≤1°C temperature overhead. The high quality of the functional devices, the high tuning efficiency, and the excellent trimming capabilities demonstrate the potential to realize low-cost, densely integrated, and ultralow-power 3D-stacked photonic circuits on top of CMOS microelectronics. 展开更多
