Tsunami waves are long waves of gravity, the wavelength of up to 100 kilometers above; its velocity equal to the acceleration due to gravity (9.8 m / s) and the product of the square root of water depth, so the deeper the water, the faster the tsunami wave, the more shallow water , the slower the speed of tsunami waves.

海啸波是重力长波，波长可达100公里以上；它的传播速度等于重力加速度（9.8米／秒）与海水深度乘积的平方根，所以，海水越深，海啸波速度越快，海水越浅，海啸波速度越慢。

A new accurate exterior trajectory model was studied based on the formertrajectory model considering eccentricity of acceleration of gravity etc.

Zhang Jianfu [40] , fixed gimmick is held in the palm to rectify after using plaster stone answer when fracture, antebrachium is outer layer squash bone of the side outside making is coriaceous embed insert, factitious ground makes far fold end to spend evaginate gently in order to prevent the happening of ancon varus, antebrachium a bit outward turning the to fracture inside extrusion when overcoming antebrachium gravity to be down surely together, yike puts an end to the happening of the ancon varus because of gravitational element be caused by.

张建福等[40]，采用石膏后托固定手法整复骨折时，前臂在外层位的挤压使外侧骨皮质嵌插，人为地使远折端轻度外翻以预防肘内翻的发生，前臂稍外旋位的同定克服了前臂重力向下时对骨折内侧的压挤，亦可杜绝因重力因素所致的肘内翻的发生。

The linear theory of antisymmetric ducted gravity waves supported by mesospheric thermal duct is presented, propagation and evolution of gravity wave packets in thermal duct is also simulated by using a nonlinear two-dimensional model. Numerical results show that lower atmospheric wave disturbance can penetrate into the duct area and be trapped.

Having little or no weight or apparent gravitational pull; light.

具有很小的重力、没有或者没有明显的重力；轻。

The result shows that gravity wave excited by the tropopause forcing can propagate stably to the mesosphere through the stratosphere so that the energy and momentum can be transferred from a region to another. In the propagation, gravity wave undergoes growth, overturning, convection and breaking. The breaking of gravity wave is the important source of convection and smallscale waves, and convective instability and overturn are the character of nonlinear phenomenon.

分析结果表明，从对流层顶激发的重力波能稳定地经平流层传到中层顶，从而将能量和动量从一个区域带到另一个区域；在向上传播过程中，重力波经历了发展、位温翻转、对流直至最终破碎的演变；重力波的破碎是对流和小尺度波动的重要的源，对流不稳定和翻转是非线性现象的一个基本特征。

Gravity wave and ozone are two interesting topics in the middle and upper atmosphere. In this dissertation, they are studied by numerical simulation and instrument development respectively.In section one, by using FICE scheme and TIME-GCM, a model of trace gases and OH airglow affected by gravity wave is set up, then the propagation of nonlinear gravity wave and the effect on trace gases and OH airglow are analyzed. The result shows gravity wave excited by tropospause forcing can propagate stably to the mesosphere through the stratosphere so that energy and momentum can be transferred from one region to another. In this process, gravity wave undergoes growth, overturning, convection and breaking. And the no-isothermal structure can accelerate the breaking of gravity wave in mesospause, and the breaking of gravity wave is an important source of convection and small-scale waves.
