this paper, on base of analyzing and comparing the correlational measure and control product of domestic home and overseas, achieves real-timely inspecting and measuring every parameter of ergograph with more advance technology of computer measure and control and a method that software can achieve the function in substitute of complex hardware circuit 本文在分析和比较国内外相关的测控产品的基础上,采用了较为先进的计算机测控技术,以软件方法代替以往需要复杂硬件电路才能实现的功能,能够对测功机的各项参数的实时检测。
temporally, annual potential evapotranspiration is from 882 to 107 lmm, with a mean value of 974mm at qiabuqia; and it is positively correlational to precipitation and temperature, so it is beneficial for plant growth because precipitation and heat ocurs at the same growth period .; spatially, annual potential evapotranspiration is from 485mm to 1174mm, with a mean value of 1027mm, and it's spatial distribution is negatively correlational to precipitation and slope, whereas positively correlational to temperature and extra solar radiation, therefore the spatio-temporal difference of water become the key factors to plant growth and plant climate potential productivity 在青海共和盆地,历年潜在蒸散平均974mm,各月潜在蒸散与降雨和温度之间是很好的正相关,所以雨热同季有利于作物生长:年潜在蒸散的空间分布范围从485?1174mm,平均1027mm,而且年潜在蒸散空间分布与降雨和坡度是负相关,与温度和大气外层辐射正相关,因此水分和温度的是影响作物水分耗散的重要因子,决定了共和盆地植被的气候生产力。
