The theoretical analysis shows that the wave-activity relation presented a nonconservative form in which the pseudoenergy wave-activity density is composed of disturbance kinetic energy, available potential energy and buoyant energy. The local change of pseudoenergy wave-activity density depends on the combination of shear of zonal basic flow, Coriolis force work and wave-activity source or sink as well as wave-activity flux divergence.

理论分析表明，拟能量波作用方程具有非守恒形式，其中的拟能量波作用密度主要由扰动动能、有效位能和浮力能三部分组成；拟能量波作用密度局地变化除了受拟能量波作用通量散度影响之外，纬向基本气流切变、科氏力作功以及由非绝热加热和水汽相变所构成的波作用源汇项对其也都有贡献。

That could lead to some far less obvious applications, such as a lateral line-enabled iPod that automatically pumps up the volume in response to the onrushing air of an underground train or similar big, noisy object.

比如一台装备了侧线系统的 iPod ，当它检测到地铁或类似的大型嘈杂物体附近的奔涌气流时，就会自动提高音量。

It is concluded that during the landfall of Saomai, the orographic uplifting is able to enlarge the rainfall of the typhoon, and also to enhance the centre potential vorticity, vertical velocity as well as the convergence of moisture flux obviously.

结果表明，台风登陆过程中地形抬升作用对台风降雨量有显著的增幅作用；台风中心位势涡度、气流垂直上升速度、水平水汽通量散度明显增大；地形抬升机制在台风登陆时刻达到最强。

MethodsSodium Hyaluronate was injected into the palatoglossal arch, palatopharyngeal arch and root of the tongue of eight Wistar rats. An electroencephalogram, electromyogram and oronasal airflow were recorded by PSG before and 4 weeks after injection when rats were under light anesthesia, which was expected to be similar to the sleep state.

方法将8只Wistar大鼠的双侧舌腭弓、咽腭弓及舌根处注射透明质酸钠，分别于注射前及注射后4周，以浅状态模拟睡眠状态，用多导睡眠仪监测动物的脑电、肌电及口鼻气流。

The mechanical properties of coal filled polymer composites The mechanical properties of coal/PP composites were investigated, and the effects of coal rank, particle size, surface modification of coupling and alkylation were discussed. The results show that the anthracite and bituminous coal all can be used as filler of plastic after pretreatment of part devolatilization and surface modification; The modulus of composites increase with the content of coal filler; The coupling agent is of no effect for reinforcing the coal/PP composites, except that there are new oxygenous function group forming on the surface in the process of pulverizing; The F-C alkylation reinforce coal (under 10μm)/PP composites obviously.

4煤填充高分子复合材料力学性能超细煤粉填充聚丙烯复合材料力学性能的研究结果表明，烟煤和无烟煤经过脱除部分挥发分的预处理后，都可用于与塑料共混制备复合材料；偶联剂改性对低变质程度烟煤/聚丙烯复合材料的力学性能基本不起改善作用，而对于经气流超细粉碎后的小粒径高变质程度烟煤及无烟煤则有一定的增强作用；烷基化改性在煤表面接枝了烷基，使平均粒径小于10μm的煤/聚丙烯复合材料拉伸屈服强度普遍提高，煤填充高分子复合材料可在较高含煤量情况下维持良好的力学性能。

The therapeutic mechanism of the method of nourishing qi, activating blood, dispersing phlegm and promoting the collaterals was supposed as that it intervened the airway remodeling and alleviated the progress of airflow obstruction of COPD by suppressing the chemo taxis of cytokines, regulating the proliferation of fibroblast cell and smooth muscle cell and preventing the proliferation and plerosis of extracellular matrix.
