集中

There were the same load characteristics of 1MW, 1.5MW and 2MW blade model, which the tensile stress, shear stress and torque of section were linearly increased with increasing of wind speed; and tensile stress of all test sections of the blade was changed greatly, but shear stress was basically the same in the same wind speed. The shear stress and tensile stress were increased obviously in the place of 388mm to centre of gyration of wind rotor comparing with other section where the phenomenon of stress concentration had for 1.5MW blade model.

对1MW、1.5MW、2MW叶片模型有相同载荷特性，各截面处的拉应力、剪应力、扭矩随风速增大而增大，呈线性增加规律；在相同风速下，叶片各测试截面的拉应力值变化较大，而剪应力值基本相同，但对1.5MW叶片模型，在距风轮回转中心388mm处与其它截面处的剪应力、拉应力比较明显增大，有应力集中现象。

The centre of mass is more or less in the middle and the contact forces with the ground around the outside, so the structure won't topple over.

Breath, muscle contraction of the buttocks; arch body, as far as possible to hold his head, right leg straight towards the ceiling (peg-leg knee in order to avoid muscle tension).

呼气，收缩臀部肌肉；拱起身体，尽量抬起头来，右腿伸直朝向天花板（膝微屈，以避免肌肉紧张）。
