The conditional symmetry instability is the intermediate process between the stable and instable states of the atmosphere. The evolution of the atmosphere from the stable to unstable state or from unstable to stable state comes through two stages. The convective-symmetric instability circulation is related with the state and type of the instability. When the conditional instability lies in the lower level and conditional symmetric instability in the upper level, the circulation will have vertical updrafts in the lower level and slantwise updrafts in the upper level. The release of conditional symmetric instability gives rise to a mesoscale rain belt.

结果表明：条件对称不稳定是大气稳定状态和条件不稳定状态之间的中间纽带，大气由稳定向不稳定或者由不稳定向稳定的演变均通过条件对称不稳定来实现；对流对称不稳定环流的形成与不稳定层的配置有关，当低层为条件不稳定而高层叠加深厚的条件对称不稳定时，对流对称不稳定环流低层出现垂直上升气流，高层出现范围较广的倾斜上升气流，对称不稳定能量释放产生中尺度云带。

The mechanism was similar to the equivalent barotropic warm core structure. The Conditional Instability of the Second Kind was the primary mechanism of development and maintenance for MCSs in case 2005. As the MCSs intensified and persisted, the latent heating was highly efficient in producing significant enhancement of Mei-Yu front systems. The LLJ intensified by Coriolis acceleration of ageostrophic wind was induced by the effect of latent heat release. The LLJ and the effect of latent heat released reinforce each other in convection system through a positive feedback process.

综合而言，2005年个案中梅雨锋面结构为垂直近乎不倾斜的浅系统，槽线系统不明显，锋面水平温度梯度微弱，低层具有强水平气旋式风切，较似正压系统，个案中MCS发展及维持机制，主要是透过CISK 过程来维持；其过程是由於低层锋面带上之辐合激发对流发展，对流潜热释放造成局部气压梯度增强，因而增强地转风；而潜热释放亦有利低层辐合之增强，产生非地转风，再透过科氏加速增强西南风，使LLJ增强，形成一正向的回馈作用。

The results show that the brush-plating coating is even and compact from section plane with good toughness and adhesion. The microhardness of the coating is 230.6HV0.5 which is 3 times of cast aluminium substrate. The wear resistance of the coating is 3 times of cast aluminium substrate. But the friction coefficient of the coating is 0.70 which is more high than that of the substrate, which is favorable for the fixed conjugate between the axis sheath and the axis seat of the gear-box.

结果表明，镀层厚度分布均匀、致密，镀层与基体界面清晰，未出现氧化物夹层，镀层的韧性和结合强度均较好；测得碱性铜及铸铝基体的显微硬度分别为230.6、74.2HV0.5；碱性铜的镀制使基体表面显微硬度及耐磨性均提高了2倍多，磨损状况明显改善。
