直线的

Up to a certain sum of the interior angles on one side of the transversal the two lines might indeed meet.

截线一侧两内角到达一定的和数，两直线可能一定相交。

It is clear that light travels in straight lines.

很明显，光是沿直线传播的。

A particle will stay at rest or continue at a constant velocity, unless acted upon by an external unbalanced force.

一切物体在任何情况下，在不受外力的作用时，总保持静止或匀速直线运动状态。

A physical body will remain at rest, or continue to move at a constant velocity, unless an unbalanced net force acts upon it.

一切物体在没有受到外力所用的时候，总保持匀速直线运动状态或静止状态。

From the variety of complex motions in the world around us we choose as our first example uniform motion.

从我们周围各式各样的复杂运动中，我们选匀速直线运动作为第一个例子。

Objects made from the edge of the uniform linear motion is also called inertial movement.

物体不受力时所作的匀速直线运动也叫惯性运动。

We cannot talk about absolute uniform motion because of the Galilean relativity principle.

因为在伽利略相对性原理中，我们不能谈绝对的匀速直线运动。

If something is moving,with nothing touching it,it will go on forever,coasting at a uniform speed in a straight line.

正在运动的某一物体，如果没有受到任何外力触动，它将永远继续作匀速直线运动。

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。
