Optik structure 1, film drive precision stepmotor handtailor by a worm will drive to the drive roller, with the co-operation of the film from the supply cassette box sent to take-up.

板滞平学布局 1、胶片传动粗劣步不退电机堵住一特制蜗轮蜗杆不兵传动传到驱动辊，在不张力辊的打扰下不兵胶片从不求片盒送到播片盒。

Also, when the waist, play skating knee, ankle need to support the body, for a long time, these parts easy local burden, strain, even affect the normal development of the bone, the bending deformation under the radical, etc.

同样，在轮滑过程中，腰、膝盖和脚踝会长时间支撑你的身体，这些部位容易接受压力和张力，甚至影响到骨骼的正常发育，甚至彻底弯曲变形等。

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。
