| 4. | The curves of the highest water level in t years in the three survey stations of huangpu river , which may be useful to the government , are given out at the end of this paper 本文最后给出了黄浦江三个水文观测站处的t年一遇的最高水位曲线,供市政设计部门参考。 |
| 5. | The result show that degree of mineralization and total hardness have both increased to different extent in majority survey station , hydrochemistry type has transformed in individual station and reflecting the deteriorated water quality 对比结果表明:大多数测站的矿化度和总硬度均有一定程度的增大,水化学类型个别站点有所改变,显示水质变差。 |
| 6. | The survey result made by hengshui environment survey station shows that the air pollution in hengshui in recent years is mainly due to coal fume and second - time dust and the water pollution is very serious and noise pollution is far beyond the standard 摘要据衡水市环境监测站监测结果表明:近几年衡水市空气污染主要属于煤烟和二次扬尘混合型污染;水质污染严重,噪声污染严重超标。 |
| 7. | This paper gives a review on the five analysis approaches of fluctuation pressure on the hydraulic structures and hydromachines : the method of probability and random process , the method of time - space correlation , the method of fitting data , the method of distribution hypotheses on the data of test survey stations , and the hydromechanics method 摘要综述了水工建筑物及水利机械上脉动压力的五种分析方法:概率和随机过程法;时空相关法;数据拟合法;根据实验测点数据分布假设法;流体力学方法。 |
| 8. | Fortunately , the modern geodetic measurements such as the global positioning system ( gps ) technique can overcome the shortage of the geological and seismographic methods in the time dimension ; and yet , the coverage of the geodetic survey stations is not sufficient . as a result , it is necessary to employ numerical simulation to investigate the continuous deformation of the crust 而以全球定位系统( gps )等技术为主的大地测量方法弥补了地质和地震学方法在时间维上的不足,但大地测量方法存在测点覆盖不足及测点地理分布不均匀的缺点,因此,要得到连续的地壳形变场有必要借助数值模拟方法。 |
| 9. | There are five survey stations in the south and north main trench of xiaoxiang reservoir . the system watches real time the change of water level and the quantity of flow in the five survey stations . so the water resource can be managed systematically and scientifically , some unrational and unscientific management for human subjectivity as before will be avoided 潇湘水库的南干渠上布置了潇湘水库站点、层板厂站点、南干渠管理所站点、汤家山村站点和大观音山村站点五个测点,系统实时监测这五个测点的水位和流量的变化,使灌区对水资源的管理达到系统化、科学化的高度水平,避免灌区的人为主观管理的不合理性和不科学性。 |
| 10. | Based on the data recorded of the highest water level in the three survey stations of huangpu river , we give out the parameters estimates by using the eight estimate procedures mentioned above respectively , then we calculated corresponding values of likelihood and goodness - of - fit . we reach the conclusion that maximum - likelihood method performs better and more stable than the others 本文基于黄浦江三个水文观测站的历年最高水位资料,分别利用这八种估计方法,求出了参数估计值,然后分别计算似然函数值和拟合优度度量值w ~ 2 ,对这八种方法进行了比较分析。 |
