为了了解坡地牧场上径流流动的复杂情况,我们采用了最简便的方法,可以叫做测针法。在许多准备测定的地点,如在草丛内及草丛的两侧,以不同的间距从坡地上方到下方都插上测针。测针是硬的铁丝,粗一至二毫米,我们使用的铁丝的长度为八厘米,但 To understand the complexities of runoff on a sloping pasture, we used the easiest way to call it a stylus. In many locations to be measured, such as in the grass and on both sides of the grass, stylus is inserted from above to below at different pitches. The stylus is hard wire, roughly one to two millimeters thick, and the wire we use is eight centimeters long but
