The muzzle is large and bulky in proportion to the size of the skull, diminishing slightly in width and depth from junction with the skull to the nose.

炮口是大型和笨重的大小比例的头骨，略有下降，在广度和深度从路口与头骨牵着鼻子走。

The results showed that the effective barrier width and area of the junction with the rough interfaces were smaller than those of the junction with the smooth interfaces.

结果表明，与界面光滑的结比较，界面粗糙的结的有效势垒宽度较窄，有效势垒面积较小。

All of them are controlled by following factors: discharge ratio, junction Angle, difference in bed height, width to depth ratio and Froude number downstream the confluences.

影响汇流口的主要控制因素有：汇流比、汇流角、河床高差、宽深比、汇流口下游干流弗劳德数等。
