实验结果表明：随着距轴肩和搅拌针距离的增大，速度场开始减弱，焊缝金属由顶面向底面、由搅拌区向旋转区的流动也随之减弱。

The result shows that the velocity field changes with the increase of space from shoulder and stir tool and the flow of weld metal from top to bottom and stir zone to rotation zone also weakens.

1990年，中国女性工资平均占比男性工资水平的77.5%，但是据2010年针对中国女性地位的一场全国性调查发现，这一数字下降到了65.8%。

In 1990, women made on average 77.5 percent of men's salaries, but the rate dropped to 65.8 percent in 2010, as shown by a national survey on the status of women.

为分析搅拌针的形状对点焊稳态过程流场的影响，建立了圆柱形、三角形和方形三种不同形状的搅拌针模型。

The models of cylindrical, triangular and square pins are created to predict the effect of the pin shapes on the material flow in the steady-state welding.
