沉浮

As the origin of tea, the development ofChina's tea industry has been proved as the most thriving advantageous industry afteryears' experience of up and down.

而作为茶叶的故乡，中国茶叶产业的发展也经历了几千年的兴衰沉浮，被历史证明是具有旺盛生命力的优势产业。

My own ups and downs attest to that .

我自己的人生沉浮能证明这一点。

Beattie and around the child's life, there are many other figures determined there.

围绕着这个孩子和贝蒂的生活，还有许多其他人物的沉浮出现。

Every night before I go to bed, I check on my two sons. I stand over them and watch their little bodies, the rising and falling of life within.

And the strong identity shows the decriminalization of the elite\'s authority.

宗教精英能动性的强弱，导致了清真寺的沉浮，寺的沉浮连带地又牵动着教众的向心力，而教众对寺认同度的增强又是对宗教精英权力的认可，从而合法化了后者的权威。

The ebb and flow of your life mirrors the ebb and flow of all life.

你的生命沉浮能反映出所有生命的沉浮。

In view of the key problem of subminiature underwater robots, structural improving,control algorithm and underwater experiment is studied. They can be described as follow: Firstly, the subminiature underwater robot should be compact in size and low cost, for which, it is difficult for us to control its balance. So that, a new kind of piston--style ups and downs system was invented, which can keep the underwater robot horizontally suspended in the water without driving force.

中文摘要本文针对超小型水下机器人在运动中存在的问题，设计了一种新的超小型水下机器人的沉浮结构形式，着重研究了其运动学动力学性能、探讨了相应控制算法、进行了水下试验，具体研究内容如下：首先，超小型水下机器人由于体积小重量轻，在水中沉浮时悬停平衡控制困难，为此进行了一种新的活塞式沉浮系统设计，该系统使水下机器人能够在无动力驱动的情况下，使其呈水平状态稳定悬浮在水中。

To rise and fall in or as if in waves; undulate.

沉浮在或似在波浪中沉浮；波浪起伏

In this design, according to the principle of crank-rocker, a special four-bar linkage swaying mechanism combined with the flexible tail fin is adopted to guarantee the stable swimming of robofish. The skillful application of hall position sensors achieves the detection of critical position of the swing link, which makes it possible to detect the position of the tail fin and control the turning of robofish. For effective raising and lowering, a mechanism using a cylinder as a pump to imitate the swimming bladder is developed.

在该方案中，应用曲柄摇杆原理，采用了特殊的四连杆摆动机构，结合柔性尾部实现了机器鱼的摆动式推进；巧妙应用了霍尔位置传感器，检测摆杆临界位置，实现了鱼尾位置判断，进而控制鱼尾来转向；研制了以气缸为压缩泵的气路沉浮机构作为&鱼鳔&，能使机器鱼进行沉浮动作。

As she looked at Warrington's manly face, and dark, melancholy eyes, she had settled in her mind that he must have been the victim of an unhappy attachment.

每逢看到沃林顿那刚毅的脸，那乌黑、忧郁的眼睛，她便会相信，他一定作过不幸的爱情的受害者。

Maybe they'll disappear into a pothole.
