在水文地质勘察工作中,参数的准确测定是极为重要的。目前,国内外虽然已普遍采用配线法、斜率法、试算法等求得,但由于影响抽水数据的因素很多,往往致使水位～时间的实测曲线与理论曲线不吻合。所以,计算结果带有一定的主观性、随机性,计算精度较低。为解决实际工作中存在的这个问题,本文拟就最小二乘法原理,利用计算机进行计算,其结果准确、唯一,且快速。 In hydrogeological survey, the accurate determination of parameters is extremely important. At present, although the wiring method, the slope method and the trial method have been widely adopted both at home and abroad, the measured curve of water level ~ time often does not coincide with the theoretical curve due to many factors that affect the pumping data. Therefore, the calculation results with a certain degree of subjectivity, randomness, low accuracy. In order to solve this problem in practical work, this paper intends to use the principle of least square method, using computer to calculate, the result is accurate, unique and fast.
