In this paper, the adjointness of the product of two differential operators generated by a third order normal and singular symmetric differential expression in the limit-circle case is discussed. The necessary and sufficient conditions which make the product operators being the adjoint operators obtained by the matrix analysis and calculation. At the same time, the adjointness of the product of the power and adjointness operator obtained.

本文首先讨论了正则和奇异两种情况下两个极限圆型三阶对称微分算式生成的微分算子的乘积的自共轭性，运用矩阵分析和计算，得到了乘积算子为自共轭算子时边界应满足的充分必要条件，同时得到了幂算子的自共轭性、自共轭算子乘积的自共轭性等乘积算子的其它若干性质。

So it is very important that the interaction of urban new region and public transportation. The strategies contain planning of urban new region and transportation, developing of new region and building of transportation infrastructure, and policies of land use and transportation. The key measures include collocating for land source, alloting for road right of way, traffic engineering, transportation demand management, new transit mode, planning of settlements and site, architectural design, etc.
