許多同志要求我們刊登介紹水利知識的講話,考虑到在大跃进形势下,各項水利工作都有了新的內容,結合这一情况对水利知識作一通俗的介紹,对大家也許是有些益处的。因此我們从本期开始試办这一講話。講話从水文开始,水文分兩部分,下期为水文水利計算。对这一工作,我們没有經驗,不知道我們拟的內容、深淺是否合适,希望同志們看了后多提意見。 Many comrades asked us to publish the speech on water conservancy, considering that under the situation of the Great Leap Forward, all water conservancy works have new contents. Combining with this situation, making a general introduction to water conservancy knowledge may be of some benefit to all . Therefore, we have tried this speech from the beginning of this issue. The speech begins with hydrology, hydrology is divided into two parts, the next is hydrological and hydrological calculations. We have no experience with this work. We do not know whether the content we are drafting is appropriate or not. We hope that comrades will make more comments after reading it.
