Aim at the question of measurement inaccurateness for the causes of disturbances and temperature excursion in the PLC multi-analog signals measure system,a kind of analog calibration method least square algorithm based is put forward.And then the detailed computation process of PLC analog signal's measure calibration is provided.

在由传感器、隔离器和PLC模拟量测量模块以及后端显示计算机组成的多路测量系统中，如果对测量参数不进行标定，则由于仪器本身的测量误差、多路测量通路之间的干扰等因素，后端测量计算机显示的测试数据往往是不准确的。

The paper introduces the studies and the development of an intellective soilless culture system on mixing and irrigating. The system is closed-circuited and its main controlling parameters are consistence value and acidity value of the nutrient liquid.

It adopt the light pillar/ arithmetic figure to show at the same time, making current trend in gauge instructioned, having again the number show the watch accuracy, clear keep the view ground measures the industry emulation in the process puts together with the close knot in amount of engineering, is front international last the manifestation gauge flies to the style.

它采用光柱/数字同时显示，使仪表既有趋势指示，又有数显表精度，清晰直观地把工业过程中的模拟量和工程量紧密结合起来，是当前国际上显示仪表的流行款式。

It is found that the amount of diuron adsorbed on the black carbon accounts for a large fraction of the amount sorbed on soil than organic matter does in low diuron concentration.

由模拟结果显示，黑炭吸附所占的比例在吸附质浓度低时较大，且使用一地区所分离的黑炭，不适合模拟其他地区的土壤与黑炭吸附行为，黑炭之吸附量在达有龙浓度为1 mg/L时系占土壤吸附量的64%。

RESULTS: Parturients did not differ regarding demographic data and initial pain score. Clonidine 150 microg , neostigmine 750 microg , and 75 microg clonidine plus 250 microg neostigmine produced ineffective and short-lasting effects. Clonidine 75 microg plus 500 microg neostigmine and 75 microg clonidine plus 750 microg neostigmine presented comparable durations of 90 +/- 32 and 108 +/- 38 min (mean +/- SD), respectively, and final analgesic efficacies, with 72.2% and 84%, respectively, of the parturients reporting a visual analog scale score of less than 30 out of 100 after 30 min.
