动量

Based on these da- ta,an optimization model to distinguish skin drag coefficient and form drag coefficient was es- tablished.

根据这些试验数据，利用动量法原理和数学优化方法构造了摩拖曳系数和形拖曳系数的辨识模型，将摩拖曳系数和形拖曳系数两项分开。

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。

We have pass the certification of the ISO9001 and ISO9002,at present we e are applying for the quality certification of the international TS16949 3 We improve the dynamo with the science, and have serial high accuracy inspection instruments which can exam the process whenever, as Germany spectra direct read spectroscopes, line measurement instruments ,gold analysis instruments, air movement instruments, ultrasonic testing equipment, all-around microscope .

大川活塞以科技提升动力，拥有系列高精度检验设备，可在各个环节对产品进行实时检验，如德国 spectro 直读式光谱仪，型线测量仪、金相分析仪、气动量仪，超声波探伤设备，万能工具显微镜。

Wet stack emission will reduce the lifting height of the flue gas, and it's not beneficial to gas diffusion; the momentum of the flue gas should be guaranteed to decrease the plume downwash and to promote gas diffusion; each of the emission index of the wet flue gas can meet the requirements for the environmental protection.

数值计算与分析表明，湿烟囱排放会增强对烟囱的腐蚀性，需采用特殊的防腐处理；湿烟囱直接排放会降低烟气抬升高度，不利于扩散；为减少烟流下洗，增强扩散，应保证烟气的出口动量；湿烟气各项排放指标能满足环保要求。

In which, for the statistic that use the phase-space formed by position 1-linear vectors and momentum 1-linear vectors in 4D time-space and the mutual reactions among these particles can be dealt as elasticity collision, they are the usual de Broglie waves.

其中，对于4维时空位置1-线矢和动量1-线矢组成的&相宇&进行统计，当粒子间的相互作用可当作弹性碰撞时，它就是&德布洛意波&。

The Simulation results indicate:(1) Exchanging of sea-air and force of dynamical and thermodynamic processes is very important to bring and maintain sea surface wind .SHF is mostly energy sources and LHF is negative effect in some area.

模拟结果充分表明：(1)感热和潜热的海气交换和动量交换对于海面风的发展和维持起着重要作用，潜热加热是海面风中最主要的能源，感热通量在一武汉理工大学硕士学位论文定区域对海面风风场有负面影响。

It is also known as one of the most poisonous naturally occurring substances.
