The control of pores is an important way to improve the performances of CBN abrasive tools.

根据需要控制气孔状态是提高陶瓷CBN磨具使用性能的一个重要途径。

The influence of different heat treatment systems on the abrasiveness of the composite was investigated by comparing the cutting time.

通过将玻璃与BMTBa(Mg1/3Ta2/3O3复合，烧结后进行热处理，合成陶瓷/微晶玻璃复合材料，通过比较材料切削时间的长短，研究不同热处理制度对材料耐磨性的影响。

The formation mechanism of the absolute instability and gyrotron backward wave oscillations is analyzed, and the methods to suppress the parasitical modes are discussed.The nonlinear theory model of gyro-TWT is consummated by considering the influence of tapered magnetic field and waveguide radius, electron velocity spread, and waveguide loss on electron beam-wave interaction. The large-signal characteristic of gyro-TWT, such as launching loss and absolute instability, are also analyzed in detail. This work establishes the foundation for the development of a gyro-TWT amplifier.

重点研究了两段损耗波导结构和损耗陶瓷结构回旋行波管中的电子注-波互作用，分析了绝对不稳定性和回旋返波振荡的形成机制和抑制寄生模式的方法；完善了回旋行波管的非线性理论模型，并考虑了磁场和波导半径渐变、速度零散、波导损耗等因素对注-波互作用的影响；详细分析了发射损耗、相位稳定性等回旋行波管的大信号特征，为回旋行波管放大器的研制奠定了基础。

The donor impurity and grain boundary combustion-supporting agent containing acceptor impurity were added successively in the ceramic powder during ceramic powder preparation, both of them can also promote grain growing and semiconductive, and the combustion-supporting agent can be good to form insulation layer in oxidizing process.

采用一次性烧成技术研制了晶界层半导体陶瓷电容器，在瓷料配制过程中先后加入施主杂质和含有受主杂质的晶界助烧剂，两者在还原烧成时促使晶粒生长并半导化，助烧剂在氧化时有利于晶界绝缘层形成。

Many experiments were carried out to investigate the relationship between the content of donor or acceptor with room temperature resistivity.

本文在综述低电阻率BaTiO〓PTCR陶瓷材料的制备和理论研究现状的基础上，提出研究中存在的问题。
