In this thesis, working condition that influence the two evaluating indicators has been analyzed on basis of experiment study. Statistics has been used to deal with the experiment data, and work out a expressions that can count the real time efficiency of total heat exchanger from temperature difference and absolute humidity difference of inside and outside air and working air volume.

The additive noise factor has relation with SOA"s linewidth enhancement factor and it is always larger than one, which means that interferometer"s output signal-to-noise is different under different working mode. Adopting feedback working mode we can obtain higher signal-to-noise ratio. The experimental results prove the correctness of theory analysis.

Introduction:Electroforming is such a process that working plate is got from copying master plate by galvanization in tank liquor; die pressing is another process that working plate is firstly wrapped onto the plate roller of die press, then the hologram effect of the working plate will be copied to base material of PET film or paper by heating and pressure.

概 况：电铸是以母版为载体在槽液中通过电镀工艺复制成工作版，模压是将工作版包在模压机版辊上，再以聚脂膜或纸张为基材通过加温加压方式，使工作版上的镭射激光效果复制到基材上的一种工艺。

The lift course of hanging device on wheat no-tillage planter was simulated by using the software of ADAMS. Some important parameters were obtained such as height of the working part relative to ground, the distance between the working part and the rear wheel of tractor, the angle of road pass and the force of hanging point, etc. The key parameters of the hanging device and its best working parameter of hanging device were found out through optimization simulation. Simulation results showed that suspension point had minimum force when variable DV_1 and DV_2 gained corresponding maximum and minimum at scope of structure limit.

应用ADAMS软件对小麦免耕播种机悬挂机构提升过程进行了动态仿真，得到了工作部件的位置高度、工作部件与拖拉机后轮之间的间距、路面通过角以及悬挂点的受力等参数，找到了悬挂机构的关键参数，通过优化仿真，得到了悬挂机构的最佳工作参数，仿真结果表明，设计变量DV_2、DV_3在结构受限范围内分别取其最大值和最小值，悬挂机构悬挂点受力最小。

It was shown that coal seam floor failure depth of working face 2121 was 32.5 to 5 m, approximately three times as deep as that of shallow working face(in genera l,9.15 to 12.0 m). Coal seam floor failure depth increased with mining depth. Potential risk of water inrush through coal seam floor of working face 2121 is much higher for deep mining than for shallow mining.

试验结果表明：该工作面底板破坏深度为32.5~35 m，比300 m采深以内的工作面实测深度(9.15~ 12.0 m)增加2倍以上，说明随着开采深度的增加，煤层底板采动破坏深度呈明显增大的趋势，因此，在水压和破坏深度二者同时增加的条件下，2121工作面深部煤层开采的突水危险性远远大于浅部煤层。
