An anatomization on the relative analyzed results is also provided. It is found that the modeling results fit the water monitoring results well with efficiency value greater than 90% and multi-year average relative error value of 3.6%. The case study indicates that the runoff-evaporation hydrological model w...

在阿克苏河流域平原区1980-1995年逐月水量平衡研究中，模拟结果比较符合研究区水盐监测的结果，模型效率系数超过90%，多年平均相对误差仅为3 6%，证明模型在干旱区具备很好的模拟精度，在我国西北内陆干旱区绿洲有进一步应用的前景。

The wind measure of the wind farm is very important. This thesis can offer relevant theory analysis and technical support for this. And on the follow-up study of this subject , there are the following suggestions:(1) In the multi-layer wind tower , an anemometer at 50 meters'must be install, in order to improve the precision of assessment of the new method further.

In this paper we have point out the error of principle formula quoted by all literatures at home and abroad to measure the refractive angle and the method of V-prism, derive from beginning the right formula of measuring refractive index by the method of minimum deviation angle and the method of V-prism.

本文指出了测量光学材料折射率的最小偏向角法和V棱镜法国内外所有文献的原理公式误差，重新推导了最小偏向角法和V棱镜法测量折射率的正确公式。基于最小偏向角法用精密测角仅可以获得±3×10-6的折射率的测量精度，然而，这些文献沿用经典的测量原理公式却具有-4×10－4数量级的原理公式误差，因此导致错误的测量结果。
