转动

You operate the trapdoor by winding this handle.

你要转动这个手柄来操纵活动天窗。

Same can be said for Triangular and Trapezoidal Screw systems, and it would be difficult to hand-rotate without some "play".

在非滚动丝杠系统中，存在同样的现象，如果没有间隙，手动转动将变得非常困难。

While with her foot on the treadle she guided the wheel in its motion.

脚踩踏板，操纵着纺轮的转动。

This is a valuable tool. If you are struggling with a background that competes with the foreground, look at whether either has linear detail (say, a squirrel on a tree branch). You can activate one of the rectangles and turn the camera so that the rectangle is either parallel with the linear detail that you want to ignore or perpendicular to the detail you want to focus on.

这一点很重要，在对前后景完全混杂的影像聚焦遇到困难时，试着找找线状细节，你可以激活某个对焦点并转动相机，使得对焦框与你不需要的影像平行，或者与需要对焦的影像垂直就可以了。

How to avoid aberration of grid shapes in the air gap region when rotor rotates, however, is the trickiness problem for the finite element method.

但是在转子转动时如何避免气隙区域内网格形状的畸变，是有限元法遇到的棘手问题。

Through two sets of good light activated triode receives the light intensity, and through comparing the H bridge control motor and rotation.

可通过对两个设置好的光敏三极管所接收的光强进行比较，从而通过H桥控制电机正反转动。

In this system, tubular scaffold can rotate slowly around own major axis. By means of this, three-dimension tissuesor organs can be cultured in vitro. Part IIIHVEC, VSMC and fibroblast were seeded onto inner surface of tubular porous PGA and PHB scaffold precoated with collagen. Sead HVEC,VSMC and fibroblast onto three porous polyglycolic acid and Poly-?

我们还特别设计了旋转培养装置，通过微型马达驱动，减速装置作用使旋转部分绕自身中心水平轴做缓慢转动，从而使置于旋转部件上的管形支架绕其正中长轴作缓慢旋转，其原理与美国 Genzrpe公司的 RCCS（Rotary cell culture system RCCS）系统相仿。

It was not till the last shred of pale Turkish tobacco had been consumed, and the grey ashes knocked out upon the topmost bar of the grate, that this pleasant dream floated off into the great storehouse in which the visions of things that never have been and never are to be, are kept locked and guarded by some stern enchanter, who only turns the keys now and then and opens the door of his treasure-house a little way for the brief deight of mankind.

直至灰白色土耳其烟草的最后一小撮也消耗殆尽，在炉栅最高的铁条上把灰白的烟灰从烟斗里敲了出来，这令人愉悦的美梦才飘浮到那最伟大的仓库里去了；世间从来不曾有过、将来也不会有的事物的幻象，都上了锁藏在这大仓库里，由某个严格的巫师守卫着，只是不时转动钥匙，稍稍打开一点儿仓库的门，让人类享有片刻的喜悦。

The grinding trace is an approximate round curve overlapped while the swing period of swing-arm is the half or the same of period of turnplate.

当摆臂摆动周期是转盘转动周期的0.5或1倍时，磨削轨迹为重合的一条近似圆弧曲线，该传动比为合理值。

In an electric accessory of a low-voltage switch, particularly an alarm switch or auxiliary switch, the switch contact is often installed on the turnplate which is driven to rotate by an external mechanism, thereby turning the switch contact to open or close.

在低压开关，如电器附件，特别是报警开关或者辅助开关中，开关触头通常安装在转盘上，转盘受外部机构的驱动而转动，从而带动开关触头以打开或者闭合所述开关触头。

Chrysanthemum of 10 thousand birthday is lax to edaphic requirement, with the arenaceous qualitative loam with fecund, good drainage had better.

万寿菊对土壤要求不严，以肥沃。排水良好的砂质壤土为好。

He unstepped the mast and furled the sail and tied it.

他拔下桅杆，把帆卷起，系住。
