At last,We carry out stability asssessment about the vegetation in virtue of the model builded in this plot.We calculate the vegetation's ecological water requirement on May 2004: canopy of Robinia pseudoacacia L require 5.2mm, Top of Melilotus albus Desr require 32.2mm, Bottome of Melilotus albus Desr require 8.6mm, Layer of soil require 17.6mm, totalize 63.6mm,Which more 22.33 mm than the contemporaneous rainfull 41.27mm.

最后通过本次研究构建的模型对项目区植被进行了稳定性评价，计算出2004年5月份复合植被的生态需水量，分别为刺槐冠层5.2mm，草木樨上层32.2mm，草木樨下层8.6mm，土壤蒸发17.6mm，总计63.6mm，这个结果比当月的多年平均(1980-2002年)降雨量41.27mm多出了22.33mm.6月初白花草木樨收割以后，次生茬生长缓慢，我们假设草木樨没有被收割，分别计算了6月和7月的生态需水量，6月份生态需水为85.64mm，7月份为78.41mm，发现6月份水分亏缺依然严重，7月份降雨完全可以满足复合植被的蒸散需求。

Terrain correction is needed when we do research on the internal structure of the Earth, the Lunar, and Mars by use of satellite gravity measurements, then calculate global Bouguer gravity anomalies. It is effective to carry out terrain correction in spherical coordinates.

利用卫星重力测量资料研究地球、月球与火星等星体的内部构造时，需要进行重力地形校正，计算全球布格重力异常，而在球坐标中实现地形校正计算是一种有效的途径。

I am hard at it, painting with the enthusiasm of a Marseillais eating bouillabaisse, which won't surprise you when you know that what I'm at is the painting of some sunflowers. If I carry out this idea there will be a dozen panels. So the whole thing will be a symphony in blue and yellow.

我拼命地干活，以马赛人喝鱼汤的热情作画，当你得知我在画一些向日葵时，那就不会使你吃惊，如果我实现了这个念头，就会有十二幅画板，这样所有的作品将是一首蓝色和黄色的交响曲。

This paper precisely conducts the special topic research in view of some important technologies of the digitized control module.(1) AC motor control circuit of PAN/TILT is designed ,which speed is controlled by AT89C51 MCU. DC motor control circuit of LENS is designed too.(2) The hardware and software of automatic temperature control is designed, which used in camera protect box without A/D IC. A kind of single wire communication IC is used in the circuit. So, the program is given.(3) A method of video switch without picture shock is discussed in this paper, and 16x8 video switch circuit is designed. AT89C51 can carry out time sequence logical control with the sync signals by request..(4) The module of real-time clock is designed, in which, LCM is used, a kind of three-wire communication IC is used too.
