In order to irrigate farmland conveniently or drain water smoothly, we must clear plants in watercourse.

灌溉及排水用的渠道因为灌溉取水的需求，或是保持排水的顺畅，必须将河道中的植生去除。

From a watercourse (there are many fish in this water) in to a lake of the south...

通过一溜排水道（排水道里有不少逆水而游的大小不等的白涟鱼）流到了南边儿的湖里。。。。。。

Through analyzing many problems on outlet drainage work from Nanyi Minor Zoon of Fuxin, in the work under construction, the paper lays stress on the systematic planning of outlet drainage from this minor zoon, which is of much importance to both the work design and its operation.

通过对阜新南驿小区室外排水工程建设中若干问题的分析，强调住宅小区室外排水系统的规划，对设计和施工是非常重要的，若不认真对待，不仅影响到生产和生活，还将会对周围水环境造成污染。

It is indicated that loosely compacted soil is of strain-softening behaviour under undrained conditions, accompanied with a rapid increase in excess pore water pressure. In anisotropically consolidated constant shear stress tests, a very small axial strain was required to induce the failure and the excess pore water pressure increased quickly at failure.

研究表明：松散填土在不排水条件下具有应变软化的特性，软化过程中伴随着孔隙水压力的迅速上升，有较高的液化势；在常剪应力排水剪条件下，具有破坏前轴向应变小、破坏时间短，破坏过程中孔隙水压力迅速上升。
