地面高度

The effects of ground on trimming and maneuvering control were studied.Taking a typical helicopter as an example,the trims for steady flight with different velocities and altitudes were first solved.Then control laws for lateral jink maneuver were obtained for helicopter NOE flight.The calculation results conform to the ground effect theory,and load factor and control variation of the maneuver can be used for reference.

以某直升机为算例，在近地飞行和考虑不同速度与高度时，分别进行了直升机稳定飞行时的配平计算，然后以侧向紧急转弯机动为例，对机动操纵规律的问题进行了计算分析，计算结果与地面效应的理论相符合，机动过载和操纵变化规律可以为飞行试验提供借鉴。

Several years of measure on space shuttle makes telemetering technology from aerospace to ground better.

几年来对航天飞机的测量经验，使得航天遥测地面技术高度完善了。

Using the seale separation method, the meso-scale structure of Mcc occ- ured near the Delta Area of the Pearl River is studied. It is shown that there is a meso-scale cyclonic circulation at 1000 hpa level and a meso-scale anticyclon at 200 hpa level associated with the Mcc. The axis of the Meso-scale cyclone center tilts northwestward with height, stretching up to 400 hpa level.

用滤波方法分析了一例发生在珠江口附近地区的Mcc的中尺度结构，结果表明，在对流层下部有中尺度的气旋性涡旋与Mcc相应，涡旋的中心轴线随高度向西北方向倾斜，在地面涡旋的上方200hPa层上，是一中尺度的反气旋性涡旋，中尺度的辐合中心和上升运动中心偏于Mcc的西部，扰动温度场也是非对称的，在对流层上部没有中尺度的暖高压。

Height to Length rati approximately 11:12 when measured from withers to ground and from prosternum to pinbone.

高度与长度的比率：基本上近似11：12（从马肩隆至地面和前胸至髋骨

Thus if we hold a PingPong ball in our hand some distance above the floor,it has potential energy but no kinetic energy.

例如我们手握一个乒乓球保持离地面一定的高度，它具有势能而没有动能。

Steep, subvertical limestone cliffs rising abruptly and majestically above the ground surface and highly variable and pinnacled subterranean limestone bedrock.

陡峭， 上升突然和庄严地在地面表面和高度可变物之上的subvertical石灰石峭壁和pinnacled地下石灰石根底。

In addition, a few of scientific questionson planation surfaces and uplifting of Tibet Plateau are also discussed in this paper, such as the function of freezing planation in the plateau formation and evolution, the magnitudes of plateau surface elevation increase and of tectonic uplifting in the plateau, ragional differences of plateau surfaces , and the giant ice caps

此外，还延伸联想到青藏高原夷平面和高原隆升的一些科学问题，如冻融侵蚀在高原地貌形成和演化中的作用，地面隆升幅度与地壳构造上升幅度，高原面高度的区域差异和大冰盖问题等。

Plunder melds and run with this jewel!
