多计数管流向探头;;单孔;;总流向;;局部流向;;滤水管 掌握地下水的流动方向,有助于研究地下水的运动规律。利用放射性单孔法可以测定地下水流某一点流动方向。 应用放射性指示剂在单孔中测定地下水流向的方法由奥地利的梅尔霍费于1963年首先提出,1964年波兰的鲍劳斯齐克等把这种方法用于现场测量。放射性单孔流向测量方法有若干种,其原理基本相同,仅测量装置结构有区别,早期有单管旋转式探头。我们从1983年7月 Multi-counter flow to the probe ;; single hole ;; total flow ;; local flow ;; drainage pipe to grasp the flow direction of groundwater, help to study the law of movement of groundwater. The use of radioactive single-hole method can be measured groundwater flow at a certain point in the direction. The method of determining the flow of groundwater in a single well using radioactive indicators was first proposed by Meerhoff in Austria in 1963 and was used by Balluschik in Poland in 1964 for field measurements. Radioactive single-hole flow measurement methods have several kinds, the principle is basically the same, only the structure of the measuring device is different, early single-tube rotary probe. We are from July 1983
