| 1. | The surface has been heated sufficiently to initiate vertical motion .
地表加热到足以引起垂直运动。 |
| 2. | The atmosphere, therefore, is heated by contact with the surface and vertical motion thereby ensues .
因此，大气由于与地面接触而被加热，并因此引起垂直运动。 |
| 3. | The process of readjustment to the statically stable reference state involves imposing vertical motions .
大气回到静力稳定参考状态的过程包含明显的垂直运动。 |
| 4. | The rotary carriage provides rotary and vertical motion to the drill string and bit
转动滑架为钻柱和钻头提供转动和垂直移动。 |
| 5. | Vertical motion of the carriage is provided by a pulldown gear case coupled by two pinions to racks on the mast
滑架的垂直移动是由一个下拉齿轮箱提供的，该下拉齿轮箱则通过两个小齿轮连接到支架上的齿条上。 |
| 6. | Considering the effect of the crustal vertical motion , the absolute variation cannot be drawn only using the tide gauge data
由于验潮站所在陆地垂直运动的影响，仅利用验潮站结果，无法获得海平面的绝对变化信息。 |
| 7. | The coupling of low - level ( convergence area lay ahead of jet on the left ) and upper - level ( divergence area lies rear of jet on the right ) jets played an important role in the course of vertical motion developing
高空急流入口区(右后方)的辐散，与低空急流左前方的辐合区互相耦合，对垂直运动的发展起到很大作用。 |
| 8. | The quasi - geostrophic process was diagnosed for a case of severe cold air breakout under the blocking situation during 16 - 18 march of 1998 . the attention was focused on the relationship between the surface anticyclone and 500hpa blocking high . the results indicate that the cold outbreak is associated with the adjustment of blocking situation in the ural area , i . e . the collapsing and rebuilding of the ural mountain blocking high . the temperature advections in the lower troposphere shown that the polar cold air invading from the northwest caused the ural blocking high collapsed , and a new ridge developed rapidly was due to the warm advection on the southwestern side which led to the ural blocking high rebuilt . in addition , the distribution of the vertical motion on 700hpa shown that the surface high splitting was related to the considerable upward motion located on the southeastern part of surface high
对1998年3月中旬一次高空阻塞形势下强冷空气过程进行了诊断分析，着重讨论强冷空气爆发前后地面反气旋活动与高空阻塞形势调整的关系。研究结果表明，强冷空气的爆发与乌拉尔地区阻塞形势的调整阻塞高压的崩溃和重建紧密相关。对流层下部的温度平流分析表明，阻塞形势的调整是由于阻塞高压上游西北方有冷空气侵入导致了阻塞高压的崩溃，而上游来自西南方向的强暖流则导致高压脊迅速发展，使阻塞高压重新建立。 |
| 9. | The results of studying show that time dilation effect in horizontal motion of compound pendulum is a result of the change in mechanism of dynamics such as acceleration of gravity , such in vertical motion of compound pendulum is due to both the change in mechanism of dynamics and the change in mechanism of kinematics
结果表明，复摆钟整体沿水平方向运动的钟慢效应是因为动力学机制发生了变化；而沿垂直方向运动的钟慢效应，既与动力学机制的变化有关，也与运动学机制的变化有关。 |
