Just during cutting , in the cutting line there has lubricating oil falling down by gravity and the flow can be adjusted , it also can be automatically on and off 横切机切割时，划痕处才有润滑油，润滑油靠重力自然流下，油的流量可以调节，油开关自动控制。
Push the button when the door is descending , the door can descend merely by gravity without the motor driving there of , which can keep the door from reverse - wrap and reverse turning to damage door 下降时按下开关，可不用驱动马违而以自动下降，遇障碍物时、不致产生逆摺、逆转而损坏?门。
The segment , es32 , is a set of sedimentation deposited by gravity flow of the near - shore steep slope sublacustrine fen , is formed out of granule roundstone and also features coarse lithology and crude grading Es _ 3 ~ 2段储层属近岸陡坡湖底扇重力流沉积，储层岩性以细砾岩为主，岩性粗、分选性差。
Driven by gravity and by their own momentum , these gases began to accumulate , first into small pockets and then into larger clumps that gradually grew hotter and brighter and evolved into stars 由他们自己的动量驾驶由重力和,这些气体开始积累,首先入小口袋和然后入逐渐增长热和明亮和转变成星的更大的丛。
The two buckets in a tipping - bucket rain - gauge rest on a pivot so that when one bucket has received 0 . 5 mm of rain it tips by gravity , empties the rainwater and allows the other bucket to start collection 当其中一个承雨斗载足相当于0 . 5毫米的雨量时，受重力的作用而翻侧，并倾出雨水。另外一个承雨斗立刻继续承接雨水。
In the motion , the direction of angular momentum vector changes every moment , because there is a torque caused by gravity act on the wheel , then the wheel rotate itself and rotate around the fixed point 车轮进动实验：在进动中，角动量的矢量方向不断改变，是因为受到一个由重力产生的力矩，使车轮在自转的同时又绕支点转动。

Mathematicians found that these highways always exist whenever two celestial bodies are revolving around each other . any object in these highways will always be attracted towards or driven away by gravity from l1 and l2 , without extra energy input 数学家发现，在两颗互相公转的天体，总会存在这些管状的曲面，当物体位处管上，便会被驱往或驱离l1或l2 。
5 , south region oil has the feature of " three high and one low " , the stratum water is type nahco3 , and plane distribution is affected by gravity differentiation and faults , which caused each fluid block separating into individual 5 、南区原油具有“三高一低”的特征，地层水为n司hco3型，平面分布主要受重力分异作用以及断层的影响，导致各断块流体自成体系。
The reactor can be shutdown during emergency by cutting off the power supply to the control rod driving mechanism which then causes the control rods to drop down to the reactor core by gravity quickly and thereby stopping the nuclear fission immediately 在需要紧急停堆时， ?须切断控制棒驱动机械的电源，控制棒便会因地心吸力而快速下坠至反应堆堆芯，立即停止核裂变。
