In the existing buckling analysis of drill stem in horizontal condition,the drill stem is thought of as an even rod with equal diameter and sticked on the below wall of well on the action of deadweight,so it was simplified as simply supported beam compressed axially and supported evenly along its length by well wall.
在现有的水平状态下钻柱屈曲研究中,一般把钻柱看作均匀的等直径杆,认为钻柱在其自重的作用下,紧贴下井壁,因而通常把水平状态下的钻柱简化为在整个长度上受到井壁均匀支承的轴向受压的简支梁。

Supporting type is suggested to be developed into 3-prop to improve adaptability besides 2-prop and 4-prop. The difference of caving difficulty degree of coal seam is the base of caving coal method at high, medium and low position. Caving with small step and open caving flashboard used widely not only cause serious mixture of coal and rock but also hinder the improvement of top coal recovery. So we suggest caving with large step or closing caving door. Four-bar-mechanism of hydraulic support restricts development of new style caving powered support. Stabilization framework of expansion link and all-shield caving tail beam at high, medium and low position are introduced here.
支架支护型式,除了两柱、四柱以外,建议开发三柱支架以改善适应性;煤层冒放性的差异,是高位、中位和低位放煤方法存在和使用的依据;目前广泛采用的小步距放煤和开放式放煤插板不仅造成严重混矸漏矸,也妨碍顶煤回收率的进一步提高,建议采用大步距放煤和可关闭放煤口;液压支架四连杆稳定机构,制约了新型放顶煤液压支架的开发,介绍了液压支架伸缩杆稳定机构及全掩护拖移高位、中位和低位放煤尾梁。

The result showed that there's inconsistence existed between the extension and intension concepts before the treatment of concept change. For instance, less than 10% of the pupils thought that the oblique prism is prism in the task of property judgment. Yet, there's approx 60% pupils choosing the oblique prism as the prism in the classified task.
结果显示,概念改变活动前学童在非典型正例和非例部份,外延性和内涵性概念存在不一致的现象,例如在性质判别作业中认为斜角柱可以是角柱的学童不到10%,但在选图作业却有约60%的学童圈选斜角柱为角柱。
