向下

The floor of the vessel has a cavity (3) therein extending downwardly from the surface of the floor, and the lower end of the liquid reagent level sensor (2) and temperature sensor (1 and 11) are positioned in the cavity.

该器皿的底板具有设在其中并从底板的表面向下延伸的凹穴(3)，并且液体反应物液位传感器(2)和温度传感器(1，11)的下端位于该凹穴内。

Second, as you might have seen the exhaust is positioned under an angle of 30 degrees downwards .

第二，正如你可能已经看到废气是定位下一个角度30度，向下。

Please note that in this case the stack grows downwards.

请注意，向下生长在这种情况下栈。

Proceed to the next area and report to the next drill instructor.

去下一个区域，向下一个教官报告。

The principal of buffer is described as follows.At impulsing down,the piston moves down and vacates the annular space.The pressure in respiratory cavity decreases to a certain level and the traveling valve opens.At that time,the liquids enter into traveling valve and cavity and the plunger is impulsed upward to carry out the gentle transient at the sudden change.When the upward impulsing begins,the respiratory cavity is subjected to pressure and the traveling valve closes.During the gradual pressure rising,the liquids in respiratory cavity effuse from the upper ventage and the sudden change of force-summing direction of plunger is relieved relying on the resistance of ventage.

其原理大致是：下冲程时，活塞向下运动，让出环形空间的体积，呼吸腔内压力下降，下降到一定水平后，游动阀打开，此时，游动阀和小孔同时进液，使柱塞在从上死点处突然改变方向向上运动时得到缓冲，实现了柔和过渡；当上冲程开始时，呼吸腔受压，游动阀关闭，在压力逐渐上升的过程中，呼吸腔内的液体从上部的小孔流出，并依靠小孔的阻力使柱塞受力突然换向得到缓冲。

The lift then began to fall faster and faster until someone hit the emergency stop button.

随后电梯开始向下坠，越来越快，直到有人压下紧急制动按纽。

However, the quantity of supply, under the influence of the ever-increasing rent will be subject to downward pressure.

然而，供应量的影响下不断增加的租金将受到向下的压力。

The next advance in evolutionism is to be able to begin with a human-designed pattern and then arbitrarily breed from there.

进化论的下一个优势是能够从人为设计的样式开始，然后从这里任意向下繁衍。

This paper presents the general methods and process of panel die design in PRO/E environment. The design can be top- down and bottomup. The emphasis is on the design and analysis of die surfaces under the PRO/DIEFACE including extensions, extension ratio, spring back ,etc.

本文探讨在PRO／E环境下采用自顶向下和自底向上的方法进行覆盖件模具设计的技术、方法和过程，着重叙述利用PRO／DIEFACE进行模具接触面设计、分析和空间曲面处理的步骤，包括模具型面、工艺余料、法兰、拉深筋、弹复角的生成和成形度分析等。

Its working principles for the saws mounted on a frame on the saw blade, driven by the connecting rod with the saw frame for resumption of exercise often, at the same time through the movements transmission Continuous feed down for sport in order to achieve the sawing of stone processing.

其工作原理为装在锯框上的锯条在连杆的带动下随着锯框作往往复运动，同时通过升降传动机构连续向下作进给运动，从而实现对石材的锯切加工。

In the negative and interrogative forms, of course, this is identical to the non-emphatic forms.

。但是，在否定句或疑问句里，这种带有"do"的方法表达的效果却没有什么强调的意思。

Go down on one's knees;kneel down

屈膝跪下。。。下跪祈祷
