This paper, with the analysis of the propagation characteristics in a lossy cylindrical waveguide and using small-signal theoretical dispersion relation, presents study on the device stability with influence of the absolute instability and the backward wave oscillation in TE01-mode lossy dielectric-load gyrotron traveling wave amplifier.

摘要该文从分析损耗介质加载金属圆波导中电磁波传输特性出发，应用回旋行波管放大器小信号色散方程，研究损耗介质加载结构TE01模回旋行波管放大器绝对不稳定性振荡和回旋返波振荡对器件稳定性的影响。

This thesis discusses the following. First, we use the condition of inference and the concept of wildhabor cone to design the addendum circle. Second, we use TCA technique to obtain the relationship between the slip track and the angle of action, which then leads to the calculation of contact ratios. We can then design the tooth face width and the numbers of teeth based on contact ratios.

本文一开始先对空间渐开线齿轮之齿冠圆范围使用齿轮干涉条件与Phillips提出的Wildhabor Cone进行设定，再利用Litvin提出的齿面接触分析方法，得到空间渐开线齿轮对在啮合过程中作用角与滑动轨迹之间的关系，藉由此关系可以建立一套设计流程来调整齿面宽以及齿数等参数，使其能符合设计需求。

The machine is completely mounted with tractor, during operation, the discs by its rotating to turn the soil, particularly, it is suitable for operation on the field with grasses, straw and stems of crops or plants, big soil resistance and with many stones and brickbat, etc.

圆盘犁是与拖拉机三点悬挂连接配套，作业时犁片旋转运动，对土壤进行耕翻作业，特别适用于杂草丛生，茎杆直立，土壤比阻较大，土壤中有砖石碎块等复杂农田的耕翻作业。

The main body of a book adopt the MRS culture medium flat to sift a lactobacillus , separate a purification by that 4 time of the above biography replaces it with reaching in a row,shape and rhabditiform the mirror is observed to hammer when checking up two kinds, the hammer shape is that the circle steeps a shape , become a pair or link up , assume strong point muchly catenoid existence; Long in being slender rhabditiform rhabditiform , strong arrangement of chain, large amount o'clock presents to send out the filiform congeries.

摘要本文采用MRS培养基平板筛选乳酸菌，经过连续4次以上的传代，以达到分离提纯，镜检时观察到链球状和杆状两种，链球状为圆泡状，多成对或串连，呈长链状存在；杆状为中长细杆状，链壮排列，大量时呈发丝状堆积。

As long as the root of the characteristic equation is within the unit circle of z-plane and the corresponding PID parameter is got, the closed loop control system is sure to be stable. Although the root of the characteristic equation can vary within the unit circle of z-plane,different value may affect the control property differently.

本文所采用的这种确定PID参数的方法，虽然可以使特征方程的根在z平面的单位圆内任意取值，但各种取值情况对变风量空调系统的控制品质的影响却不同，因此，要对各种特征方程的根的取值情况进行寻优，本文采用遗传算法对特征方程的根进行寻优，从而使控制器的参数得以优化。

Based on classical Hausdorff distance and the new definition of distance, a new similarity measure, i.e., minimum maximum circular measure was defined.

在此基础上，对经典Hausdorff距离进行改进，提出了一种新的度量，即最小最大圆度量。

Before conducting the study, students believed that Heat could not influence gas and liquid volume.Matter didn't have thermal expansion. Metal ring's diameter will shrink after heating. The melting quantity of salt is much quicker and faster than sugar in the same temperature or water. Only metals can conduct heat, but not wood, glass, plastics. The quantity of heat is by steam way disappearing.

一、学童对「物质与热」的迷思概念有：(1)「热对气体、液体体积不会有影响」的概念，(2)听过热胀冷缩的语词，但是对原因不明了，(3)金属双圆环加热后，内环孔的口径会变小，(4)同温度且等量水，盐的溶解量比糖多、也比糖快；(5)木材、塑胶、玻璃不会传热，金属才会传热；(6)以为热量是以水蒸气方式散失，(7)冷气机应安装在高处，冷房效果较佳；(8)误认为金属是良好的保温材质。
