It shows that it is possible to increase the start oscillation length by tailoring magnetic field's amplitude and its period without changing the synchronous condition of the fundamental wave; in the meantime, when there are two or more azimuthally asymmetric space harmonics in the high power broad-band helix TWTtraveling wave tu...

与此同时，对起振长度、初始非同步速度参量随皮尔斯增益参量、空间电荷参量、损耗参量等的变化，以及在超宽带行波管中当存在两个或多个角向非对称空间谐波时，起振长度、初始非同步速度参量随周期永久聚焦磁场的变化进行了研究。优化设计聚焦磁场、电子注和螺旋线慢波系统的参量可以对螺旋线行波管的稳定性分析提供必要的依据。

The synthetic gas and ash composition heat transfer and flow in vertical pipe of coal gasifier are simulated and analyzed by the theory and program presented. The temperature、velocity and concentration variations of synthetic gas and ash composition are accomplished. The influences of coal gasifier working condition and vertical pipe parameters on the gas and ash cooling process are discussed. The law of solid-gas two phase turbulent flow and heat transfer is further revealed.

本文还应用上述理论和程序，在国内首次对气化炉激冷室下降管内合成气和灰份的流动和传热过程进行了数值计算和分析，得到下降管内合成气和灰份的温度、速度和浓度等参数的变化，还讨论了气化炉运行参数和下降管结构参数如气化温度、下降管尺寸、灰份性质等参数变化对合成气降温过程的影响，进一步揭示了下降管内气固两相的流动和传热规律。

Importantly the combination of clear cap (52) and steel feed tube provides all of the advantages of both, that is, adequate strength in the feed tube and knife and the ability to see under the cap.

重要的是透明的聚合物盖52和钢进料管的组合提供两个优点，即进料管和刀片有足够强度，和能查看聚合物盖下面的情况。

Chou Ch'u-Fei , a traveler among the Ch'i Tung natives then, reported that drinking bouts in this kingdom had been perfected by means of a two-foot-long bamboo straw which automatically regulated wine consumption, giving large-throated and small-mouthed drinkers equal advantage.

周去非，一位当时正好身处溪峒土著之中的旅行家，在他的著作中报道说，在这个王国中，喝酒这种活动已经因为一种长约两英尺的竹吸管而变得完美无缺，因为这种竹吸管可以自动调节酒的消耗，让喉咙粗大和嘴巴窄小的饮者重新回到同一个起跑线上。

A seal for sealing against a cylindrical surface, for example the facing surfaces of two concentric pipes, or the facing surfaces of a pipe and a plug or cap, is actuated by a series of elongate shape-memory material actuators (40) which are arranged around the cylindrical surface.

一种用于密封在一圆柱形表面上的密封装置，所述圆柱形表面例如是两个同心管的相对面，或一个管和一个插塞或盖的相对面，所述装置由一系列细长的形状记忆材料致动件(40)致动，致动件围绕圆柱形表面设置。

Based on the integration of the results of acoustic andfluid dynamic analysis, this paper points out that synthetical acoustic and fluiddynamic performance of muffler can be obtained by using square expansion chamber,by stringing together several podgy expansion chambers, by applying noise absorbingmaterial on chamber walls, by making chambers and pipers co-axial, by adding filletson the end of intruding pipes, and by making the diameter of outlet pipe a little greaterthan the diameter of the inlet pipe.

通过综合流体力学和声学有限元两方面的分析的结果，指出了采用方形扩张腔，采用多个短粗扩张腔串联，扩张腔壁面附吸声材料，使各管道同轴，在插入管端口加上圆角，并且令出口插入管管径略微大于入口插入管管径可以使消声结构获得最佳的声学和流体力学综合性能。

Breath, muscle contraction of the buttocks; arch body, as far as possible to hold his head, right leg straight towards the ceiling (peg-leg knee in order to avoid muscle tension).
