Remote sensor lens design based on the matching of materials Tang Tianjin1,a, Sun Dewei1,b 1Beijing Institute of Space Mechanic & Electricity, Beijing 100094 atianjin79526@aliyun.com, bsdw508@163.com Key words: materials, thermal characters, remote sensor, athermatilization, optical and mechanical compensation Abstract: Thermal characters matching optimization of the remote sensor lens materials determinates the thermal adaptive faculty of the sensor, therefore become the most important influencing factor which will decide whether the sensor can work.
Formulas are listed to illustrate the principle of the athermatilization which is realized through the reasonable matching of different materials.
Generally, lens are designed, assembled and tested at normal atmospheric temperature, but when the remote sensor works on orbit, the characters of the optical materials and bracing structure materials will change as the change of the working temperature, the best focus position will alternate and the performance of the sensor will fall down.
Analysis of the material’s thermal difference Change of the working temperature will cause the change of the characters of the materials, mainly including several respects as follows: Change of the index Based on the principle of the engineering optics, the index of the optical materials is relative index whose unit is the index of air, in other word, the relative index of the material is the ration of the absolute index to the air index.
Many groups of solutions about the optical materials and structure materials can be achieved through solving equations.

The eroding of chloride ions has clearly debased security of laterite engineering.
Introduction Laterite, also called red clay or carbonate rock weathering crust, which is used as the main material in earth dam reinforcement for a long time for its good engineering properties, is widely distributed in Hainan, Guangdong, Guangxi and southwest regions in China.
Above all, silicon dioxide, ferric and aluminum oxides which act as the main viscous substances in laterite have high strength, which is the key for laterite to be used as good material in dam construction.

Study on the Environmental Impact Assessment Index of Traffic Engineering Based on the Low Carbon Economy Perspective Qi Guo1,a Dan Li1,b Qing Fang1,c 1School of Hydraulic & Environment Engineering, Three Gorges University, Yichang 443002, China aguoqi@ctgu.edu.cn, b664668882@qq.com, c648472306@ qq.com Key words:low carbon economy;traffic engineering;life cycle;environmental impact;index Abstract:The traffic engineering environment impact assessment generally considered the influence on environment of traffic engineering operation stage only, relatively ignored the influence on environment of traffic engineering construction stage and demolition stage.
This paper gives comprehensive analysis on the influence on environment of traffic engineering at the view of the whole life cycle of traffic engineering.
The various stages of carbon emissions are taken together, in the construction phase of traffic engineering, building materials production, processing, transportation and construction process will generate a certain amount of carbon emissions; In the operational phase, transport, transport facilities, ventilation and heating will also generate carbon emissions;, the equipment which are use to remove will produce the same carbon emissions. 2.3 Energy Consumption The energy consumption is investigated energy consumption of traffic engineering in the full life cycle.
The quantification of energy consumption of building materials production can be determined by the energy consumption of building materials production showing in Table 2 [6].
