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。

In our country, the development of road transportation is mainly simple scalar expansion of low level, The growth of factor productivity contribute small to the economy increase, and the mainly character is: The development of road passenger transport and road freight is mainly the expansion of quantitatively and scalely;the development of road transportation depends on the infrastructure's high devote and market demand increase; technical is draggle and energy consumption is high, the Structural upgrade of industry is slow.

在我国，道路运输业的增长以低水平的简单数量扩张为主，要素生产率提高对增长的贡献度较小，具体表现为：道路客货运输服务的发展以数量和规模的扩大为主；道路运输业的发展仍然依赖于基础设施建设的高投入和市场需求的扩大；技术水平较低，能耗高，产业结构升级步伐缓慢。

It is undeniable that in the past have experienced property management low technological level and low level of management, the development of low-life treatment process; It is undeniable that today's property management in some areas remains "three low" position; However, with the property management companies to increase the intensity of support, property management and the sound system, raising the level of real estate development, It was an improved economic situation and changes in consumer values, property management and low technology content, the low level of management, the treatment of low-life into high-tech and high-level management, high-life treatment, is an irreversible trend of social development; property management become enviable career, will also be close at hand.

不可否认，过去物业管理曾经经历过低技术含量、低管理水平、低生活待遇的发展过程；也不可否认，今天物业管理在一些地区仍然处于"三低"的境地；然而，随着政府对物业管理企业扶持力度的加大，物业管理法规制度的健全，房地产开发水平的提高，人们经济状况的改善和消费观念的改变，物业管理的低技术含量、低管理水平、低生活待遇变为高技术含量、高管理水平、高生活待遇，将是不可逆转的社会发展趋势；物业管理成为令人羡慕的职业，也将为期不远。
