The flow .structure and river bed deformation near piers when an angle exists between the trend of piers and the direction of main-flow will be different from those when the angle equal to zero, such as the flow-obstructing width will increase, the diversion function will occur, the partial scouring pits get larger and deeper, and the main-flow and thalweg within a certain distance downstream the piers will deviate to on...

对桥渡附近的河床变形进行了实验研究，认为在桥墩走向与主流方向存在一定偏角时，桥墩附近的水流结构和河床变形将会不同于没有偏角时的情况，如增大阻水宽度，起到导流作用，使局部冲刷坑增大变深，以及能使下游一定范围内主流位置和深槽位置向某一侧发生偏移。

The distortion of high-strength Aluminum alloy in the process is widespread. And thae residual stress is the key factor that caused distortion.

By use of the system of the equations, large deflection of an elastic cantilever subjected to a concentrated force at its tip is analyzed and some comparison between the system of equations of the geometric central axis and those of the neural axis is made.

结果表明，当载荷较小时，2种理论计算出的弹性大挠度悬臂梁的变形曲线差别很小；而当载荷较大时，2种理论计算出的弹性大挠度悬臂梁的变形曲线存在比较明显的差异。

IF REPLACING BY PIECE, REPLACE FACE PLATE FIRST USING BACK WELDING,THE SIDE PLATES,EDGE PLATES AND MEMBERS INSIDE SHALL BE STRAIGHTED IF DEFORMED,AND THEN STARTED FITMENT, AND THEN SECURED,WELDING. AT THE SAME TIME, THE CUTTING FLAME SHALL BE CONTROL WHEN CUTTING, AND FORBID TO CUTTING THE BASE

舱盖板整块换新的，可以先换新面板，但面板割除时要采用退割法，里面的侧板、边板和构件如变形需校正后才能装配面板，全部装配好后再定位焊接好，同时在切割的时候尽量控制切割火焰，并严禁割伤母材，从而加大变形量。

Sliding of grains boundary and interface was a main mechanism of superplastic deformation of metal matrix composite. Dislocation did major action to coordinate this two sort of slidings, in the meantime, stacking-faults and twin-crystals did asistant action.

经过对上述问题的研究，本文对金属基复合材料超塑变形的微观过程给出概括性的描述：金属基复合材料超塑变形的主要机制是晶界及界面滑动，位错对实现这两种滑动起主要的协调作用，层错与孪晶则起辅助的协调作用。
