In Smashing technology teaching, because of short time, lower level of students movement and smashing move s complex technical reasons, it makes smashing technology teaching more difficult .
在扣球技术教学中,由于教学时间短,学生运动水平较低。
补充资料:自紧圆筒
分子式:
CAS号:
性质:在单层厚壁圆筒内施以较设计压力为高的压力,使简体内壁产生局部塑性变形,外壁仅产生弹性变形;压力卸去后,外壁有残余拉应力,内壁有残余压应力。这种由外层筒壁自紧效果而使简体强化的简体称自紧圆筒。经过这样处理的简体,承受内压时,筒壁内沿径向方向的应力分布较为均匀,故承载能力增强。这种使筒体承载能力增强的方法称为自增强法。
