This means that not only were they at different altitudes but also their orbits intersected at about a 10-degree Angle. There was no danger of collision.

这意味着他们不但处于不同的高度，轨道也有约10度的交角，没有碰撞的危险。

Throughcalculation of temperature rising callused by them, melt criterion is given, the thickness of melted layer near explosive welding interface with small collision Angle is estimated.

通过计算绝热压缩温升和畸变形能沉积产生的温升，给出熔化判据，定量估计出了在小碰撞角下爆炸焊接界面熔化层厚度。

The increase of the angle between centerline of nozzle orifice and axis of secondary combustor can promote collision number, but the effect is small.

喷口中心线与补燃室轴线的角度增加对碰撞有催进作用，但影响效果相对较小；

The severity of the laboratory test was equivalent to an oblique collision with the rocky surface of the Earth - a comet coming in at an angle of less than 25 degrees from the horizon, rather than head on (perpendicular to the Earth's surface).
