先母

The first direct measurement with micrometer diameter piston skirt, and then dial indicator card installed and the initial installation of the amount of good cylinder rod inserted card table micrometer mounted on the anvil between the seat and the measuring bar, adjust the volume of cylinder table Interpolation of the extended length of rod, when the dial indicator has small hands around 1.5-2 cell volume preloading lock locking rod inserted mother, and a large dial indicator to zero adjust the final stretch to the volume of cylinder table into the Cylinder Sleeve, large dial indicator hands than "zero" low value (considering the small hands reading) is the piston and cylinder liner with the space.

2先直接用千分尺测量活塞裙部的外径，然后将卡装好百分表和初步安装好插杆的量缸表卡装在千分尺的砧座和测杆之间，调整量缸表插杆的伸出长度，当百分表的小表针有1.5-2格左右的预压量时锁紧插杆锁母，并将百分表的大表盘调整到零，最后将量缸表伸入气缸套内，百分表大表针比&零&低的数值即为活塞和气缸套的配合间隙。

After that there gallop from Temple Bar, old lady, I won't trust your fore-legs till I get you on the level ,' said this hoarse messenger, glancing at his mare.

&从法学会到这儿这一趟跑完，我的老太太，我对你那前腿就不大放心了。我得先让你平静下来，&这沙喉咙的信使瞥了他的母马一眼，说。

IF REPLACING BY PIECE, REPLACE FACE PLATE FIRST USING BACK WELDING,THE SIDE PLATES,EDGE PLATES AND MEMBERS INSIDE SHALL BE STRAIGHTED IF DEFORMED,AND THEN STARTED FITMENT, AND THEN SECURED,WELDING. AT THE SAME TIME, THE CUTTING FLAME SHALL BE CONTROL WHEN CUTTING, AND FORBID TO CUTTING THE BASE

舱盖板整块换新的，可以先换新面板，但面板割除时要采用退割法，里面的侧板、边板和构件如变形需校正后才能装配面板，全部装配好后再定位焊接好，同时在切割的时候尽量控制切割火焰，并严禁割伤母材，从而加大变形量。

The results show that the plasticity zone and dynamically quiescent layer become fine equiaxed recrystallisation under the thermo-mechanical effect, the grains in the heat-affected zone grow up because of the effect of friction heat. When the rotation speed is 2 500 r/min and the welding time is 12 s, good joint is achieved, and the tensile shear strength of the joint reaches 9.24 kN. The tensile shear strength of spot increases with increasing tool rotation speed, with increasing welding time, the strength increases first, while then reduces. The microhardness of plasticity zone is high, but is slightly lower than that of the base metal, the minimum value of microhardness is in the heat affected zone. When the energy input of joint is high, the fracture type of spot is mode Ⅰ, and the tensile shear strength is high; on the contrary, when the energy input of joint is less the fracture type of spot is mode Ⅱ, and the strength is low.

结果表明：塑性区和动态静止层的晶粒在热和力作用下发生动态再结晶形成细小的等轴晶，热影响区的晶粒在摩擦热作用下长大变粗；搅拌头旋转速度为2 500 r/min，焊接时间为12 s时，可以获得力学性能较好的焊点，焊点的剪切强度达到9.24 kN；焊点的剪切强度随搅拌头旋转速度的增大而增大，随焊接时间的延长先增大后减小；塑性区的显微硬度较高，但略小于母材，接头显微硬度的最小值分布在热影响区；焊点热输入量较多时，接头为Ⅰ型断裂，焊点的剪切强度较高；焊点热输入量较少时，接头为Ⅱ型断裂，焊点的强度较低。

After being treated with DTT, the germinal vesicle migrates and breaks down and the chromosomes are rearranged to the metaphase plate, followed by extrusion of the first and second polar body.

经DTT诱导后，生发泡发生移动并破裂，染色体排列到赤道板上，然后第一、二极体先后排出，诱导成熟的卵母细胞排出极体的时间与自然受精的卵子一致。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
