Because in general there is no soft zones notebook, it is necessary to use DOS software under inspection is very difficult in general, Chinese multi-DOS startup disk U emergence 1.0 solved this problem, these two software will be able to view the notebook under DOS information, but now the use of DOS software testing is very scarce, you can find basically no way for the laptop, currently only found in relatively good AIDA16 2.10 +, Fortunately, now in the testing machine under DOS situation rarely encountered, but prepared to react to them (tell the truth, should there be any problem is basically parallel distributors will not let you casually testing machine software, which directly go for a well).

因为现在笔记本一般没有软区，要使用DOS下的验机软件一般很困难，中文多功能DOS启动U盘 1.0 的出现就解决了这个问题，以上两个软件配合使用就可以在DOS下查看笔记本的信息了，不过现在在DOS下使用的验机软件十分稀少，可以找的到的基本上没法用于笔记本电脑，目前只发现了AIDA16 2.10+比较不错，好在现在在DOS下验机的情况也很少遇到，不过有备无患嘛(说实话，如果真有问题的话基本上水货经销商是不会让你随便软件验机的，这种情况直接走人换一家好了)。

The paper focuses on the tetraploidy black locust on Loess plaeatu of West Shanxi province, applys steady state promoter method and image processing technology to study the days transpiration water consumption in different weather ,different seasons and different site conditions,has primary analysis on the impact of environment on the transpiration and carries on the calculation to the tetraploidy locust tree by the single leaf water consumption to the single tree water consumption in CaiJiachuan watershed; Uses fast weighing method to measure and analyze the transpiration water consumption of five different herbs under the tetraploidy black locust forest (Capillary Wormwood,Vanilla,Agropyron Sristatum , Common Sowthistle and Medicago Sativa) in short time, in the same and different growcrop,and calculates the average transpiration water consumption per square metres ;the soil colome weighing method was used for determining diumal variation quantity of soil moisture evaporation, analyzing the dynamic variation and caculating the total quantity of soil evaporation water consumption from May to August ; then 5 kind of suppositions about the types of surface vegetation coverage are proposed in experimented site and the total evapotranspiration water consumption are calculated under 5 suppoitions ,aim at providing preliminary theoretic basis for ascertaining the transpiration water consumption of tetraploidy black locust forest,controling standing forest density and optimizing the forest grass deploy on loess plaeatu of west Shanxi province .
