When the speed of piton changes from several positive meters per second to negative during short time , a huge transient impacting force acts on the piston. The force spreads in the piston with stress wave. Converging force will become at some sections, which can destroy the piston.

从风动冲击器的工作原理可以得知，风动冲击器的活塞在高压气流的推动下，反复冲击钻头，冲击时活塞的速度由向下的几米每秒在极短时间内反弹为向上的速度，因而对活塞产生一个极大的瞬时冲击力，该力以应力波的形式在活塞内传播，就会在活塞的某些断面产生应力集中，造成活塞的破坏。

To confirm the hypothesis that the pathogenic mechanism of air infusion in the circulatory system is not bubble blockade of blood vessels but the consequence of anoxia of the vital organs,different amounts of air were injected into the great sapenous vein of 22 dogs,and then heart rate,cardiac rhythm and bubble sound were monitored with a Doppler probe at the precordial region.

为探讨循环系统内注入空气致病机理，向22只狗大隐静脉内注入不等量空气并在心前区用Doppler监测心率、心律和气泡音。结果发现，维持心前区Ⅳ级气泡音的17只狗，依次出现呼吸和心率加快、心律紊乱、心率缓慢、腹式呼吸加强，其中12只狗继续缓慢注入空气至呼吸停止，任选10只狗胸外按压，8只狗复苏后行为无异常，2只狗未能复活。另2只狗呼吸停止后立即尸检，可见右心房、室、腔静脉和肺血管中有大量气泡。

As a first step to industrialize this focusing coal liquefaction technology, it is essential to study the multiphase transport characteristics of this new type reactor. In this paper, mass transfer and mixing characteristics of a three-phase continuous loop reactor with a concentric draft tube were measured by the dynamic dissolved oxygen and saturated KCl solution pulse trace methods,with glass beads as solid phase, air as gas phase and tap water as liquid phase, respectively.

本文在同心内置Φ 0.14×1.5m导流筒的Φ 0.2×2.5m有机玻璃环流反应器中，以空气和水为气、液相，玻璃珠为固相，分别利用动态溶氧法与饱和KCl脉冲示踪法测量了液相体积传质系数和轴向分散系数，考察了表观气速、进料浆速、固含率、固相颗粒直径、液相表面张力以及操作方式对上述两个传递参数的影响规律，并将实验结果关联为量纲为1关联式；同时，根据环流反应器的结构特点，建立了传质系数分区模型和轴向分散系数分区模型且分别获得了解析解，对床层传质和混合的不均匀性做了理论分析。

To calculate the pressure drop of cyclone must consider the tangential velocity. Researchers regarded inner vortex as quasi-forced vortex and outer vortex as quasi-free one before.

旋风分离器阻力损失的理论计算离不开切向速度分布，以往在切向速度的研究中，认为内涡旋是准强制涡、外涡旋是准自由涡。

The invention relates to an electric machine (10) which can be operated as a motor or a generator. Said machine comprises a rotor (26a, 26b) rotatably mounted in a housing (12), a rotor shaft (24) which extends beyond the housing (12) and a plurality of electromagnet components (28) that are statically arranged in the housing at a distance from the axis of rotation of the rotor in evenly distributed angular distances. Said electromagnet components have each a wire-wound coil (30) consisting of a coil core (32) which carries one or more conductors.

本发明涉及一种可作为电动机或发电机工作的电机(10)，它包括一个可旋转地安装在外壳(12)内带一根伸出外壳(12)的转子轴(24)的转子(26a、26b)，以及包括多个离转子旋转轴线一定距离处按均匀的角向间距位置固定地布置在外壳内并各有一个支承着由一根或多根导线组成的线圈绕组(30)的线圈芯(32)的电磁构件(28)。

Larch Forest occurs on the west-faced slope behind of Yangyuchang between3400-3600 m in the Lashihai region, which consist of the Larch-Rhododendron Communities with R.

大果红杉林在拉市海流域内见于洋芋场村寨后海拔3400-3600米范围内的西向坡面，面积较少。

Under the plastic-mulched ridge and furrow cultivation, the average soil water content of furrow (12.7%) was significantly higher than that of ridge (9.1%) at the soil depths of 20-100 cm. The locally compacted ridge served as a water flow barrier and a rainfall collection area under locally compacted ridge and furrow cultivation, and the water content of furrow was significantly higher than that of ridge in the same soil depths, which was similar to the characteristic of soil water distribution under plastic-mulched ridge and furrow cultivation. No significant differences were found in soil water content of furrow between locally compacted ridge and furrow cultivation and plastic-mulched ridge and furrow cultivation, with the same efficiency of water collection.

相对于自然垄沟，膜垄的集雨效果明显，沟中土壤平均含水量显著高于垄中，20～100cm土层范围内平均土壤含水量分别为12.7％和9.1％；成垄压实土壤水分在剖面分布状况与盖膜垄沟的水分分布相似，水分向沟内集中，沟中土壤水分含量显著高于同一土层深度处垄中土壤含水量，且与盖膜垄沟处理下沟中土壤水分含量无显著差异，在集水和聚水方面表现出和膜垄的相似性。

First of all, horizontal swing to solve big problems, re-allocation of a motor sleeve (with the bronze with stent hole so), so that the electrical sleeve just in bronze wall bracket can rotate, reducing the gap; further axial movement to solve the problem with the motor shaft with Hexagon Hexagon washer so thick 0.6mm.
