Water quantity prediction is the base and premise of water price calculating . this paper uses moving tendency forecasting modeling , gm forecasting modeling and bp neural forecasting modeling to forecast the water requirement of the future , evaluates the forecasting results , and confirms the forecasting results ; the industry water price elasticity index and the resident water price elasticity are calculated with the multi - linear regression method ; the water resources value is evaluated with the marginal opportunity cost method considering the transferring water , other parameters are evaluated and estimated by using some methods of connecting with objective laws and estimation 用水量预测是水价制定的前提和基础，本文在进行水量预测时，采用移动平均法、灰色预测法和bp神经网络进行预测，并对预测结果进行了综合评价，确定出合理的预测结果；采用多元线性回归方法确定工业用水价格弹性和居民生活用水价格弹性指数；采用跨流域调水情况下的边际机会成本方法确定当地的水资源价值；采用主观判断和客观规律相结合的方法对其它一些参数进行了确定。
So by this method , we can test the water content of the raw cement slurry through testing the velocity of the detector , it is certainly that it can test other slurry , such as paper slurry , mud slurry , mine slurry ctc . the fluid mechanics charactoristic of the slurry is complex , therefore it is difficult to establish the two - dimension or three - dimension mathematical modle to decide the relationship between the water content and the revolving speed of the detector . so the research for rotational detector in this topic is through the method of proper regressive analysis of experimental datas to establish the relation among the water content , the palse and the voltage 料浆的流体力学性能是复杂的，要想通过建立二维或三维的仿锥形旋转式检测头在料浆中旋转的流体力学数学模型，来确定料浆水分含量与检测头的转速关系是十分困难的，甚至是不可能的，因此本课题对于旋转式检测头的研究，是通过对实验数据进行多元线性回归的处理方法，建立起水分含量与红外线对管输出的脉冲数p及电源电压之间的关系。
