The result shows that multiple inlet is better than single inlet , and that inlet with buffer is better than that without buffer . other optimal design structures are also adopted . the gas manifold with optimal structure make oxygen much evener for each cell 结果表明多进口比单进口，有)比无隔板、扩压型进口比非扩压型进口、椭圆台进口比圆台进口的进气箱结构更易实现电池堆中每个单电池进气量的均匀化。

In general , the content which is studied in this paper can be briefly summarized as follows : 1 the conic shape of nutrition plug which suit the growing condition of the corn seedling is made certain through contrast study on the root grow character between the corn and vegetable seedling ; then the plug size which bulk is smaller and meets the growing condition of com seedling through cultivating the corn seedling 全文内容概括起来主要有以下几点： 1通过对玉米秧苗根系生长特性与蔬菜根系生长特性的对比性试验研究，确定了适合玉米秧苗生长的圆台形钵体；进一步通过玉米育苗试验，确定了能够满足玉米育苗生长需要的、体积相对比较小的钵体尺寸。

3 based on the shape of conic plug , the profile modeling - annulus equipment which can make plug in a line is designed . this equipment can not only solve the plug lining - up problem in mechanizing way when plug seedlings are transplanted , but also can raise the working speed of no - tillage transplanter , and reduce the working intensity of operator 3利用圆台形钵体的外形特点，采用仿形导向轮式排队装置，解决了栽植过程的钵苗机械化排队问题，提高了免耕栽植机的作业速度，减轻了操作人员的劳动强度。

Disk chuck has been adopted in 74 series vertical shaft rotary die grinders , which can grind to the internal hole , excircle of large workpieces and workpieces with shoulders . die can work and grind to r - arc without removing guede - pole , and grinder head can rotate in the range from + 45o to - 45o . accordingly , the life of die is longer than before and accuracy of the die is stable 74系列立轴圆台模具磨床采用花盘式工作台，可对较大工件内孔、外圆和带有台肩的工件进行磨削，冲模模具可以不拆导向柱进行磨削及r弧磨削，提高模具使用寿命，保证模具使用精度，磨头可旋转45 。
