反射计

This paper introduced algorithmic method of light distribution design with the help of light distribution calculation and illumination of test points. It gave the detail about Ray Tracing and point by point arithmetic, presented a design tactic of multi-surface reflector.

从计算光形分布和测试点的照度值两方面介绍了配光设计的计算方法，具体运用了光线追迹法和逐点计算法，并给出了用于近光灯的多曲面反射体的一种设计策略

Peanut or rice wereplanted in the large-scale weighing Lysimeter,pit plots,and standard runoff plots,wherehigh,moderate,and low soil moisture levels were designed as 3 treatments,assemblingwith some instruments such as time domain reflectometry,portable photosynthesis system,dew point microvoltmeter,and porometer.

季节性干旱缺水严重制约着我国红壤区农业的持续发展。1999～2000年在中国科学院红壤生态实验站，利用大型称重式蒸渗仪、测坑小区和径流小区，配合时域反射仪、光合蒸腾仪、水势仪及动态气孔阻力计等仪器，设计高、中、低3种土壤水分处理，进行了花生和早晚稻试验。

A simple and inexpensive optical fiber vibrometer with reflectivity and illuminating power compensation was presented.

介绍了一种结构简单、价格低、带有反射率和亮度补偿的光纤振动计。
