汉化HEC-RAS软件！！！

本人想汉化HEC-RAS这个软件，基本界面已经汉化得差不多了，，，不过英文一般，时间有限，故上来发帖之，，求各位帮忙～！
计划每日3句翻译，论坛上大家共同讨论，然后得出最恰当的翻译结果用之以汉化～！

1、Monitor this hydrograph for adjustments to computational time step

2、During subcritical analysis, with the exit loss set =1.0, the projected WSEL in culvert has a lower energy than the downstream energy. Most likely, the downstream cross section blocks part of the culvert or the ineffective area is set too far in. Instead of projecting the WSEL, the program did an energy balance to get the WSEL inside the culvert at the downstream end.

3、There is an Internal Boundary between the last and second to last cross sections in the reach. In an unsteady analysis, internal boundaries must be more than one cross section away from the end of a reach. Copy the top or bottom cross section of the reach to put another cross section between the end of the reach and the internal boundary.
