The type and the size of epidermis cell, epidermis hair, stomata apparatus and inside blade tissue;Ascertaining by measuring the epidermis cell thickness of the stem, the type and density of the epidermis hair,the density of lenticel; the thickness of cortex, phellogen, vascular tissue and pith;And calculate the ratio of cortex and radius, the ratio of vascular tissue and radius, the ratio of pith and radius…….

测定出叶片表皮细胞、角质层和厚角组织厚度，表皮毛、气孔器和叶内组织的类型、大小等；测定出茎的表皮细胞厚度，表皮毛的类型和密度，皮孔密度，皮层、栓皮层、维管组织和髓的厚度，计算皮层与半径之比，维管组织与半径之比，髓与半径之比等。

And there is an approximate linear relationship between the momentum of the automatic mechanism and the length of the gas tube.

如β=〓与β=〓相比较（β角单位为弧度，其定义详见正文），前者与后者对应的气室最大压力之比可达65%，而对应的自动机动能之比可达60%；导气管内径对气室内气体压力冲量和自动机动能的影响存在极值点，且该极值点随导气孔的增大而有规律的增大；导气管长度对气室最大压力、压力冲量和自动机动能的影响呈单调递减规律，且自动机动量与管道长度之间近似符合一直线关系。
