So the process is offered using isomerization with separation. 1,2,4-trimethylbenzen is converted to 1,3,5-trimethylbenzen by isomerization. By means of precise distillation mesitylene is separated from products of isomerization as much as possible with high purity. 1,2,4-trimethylbenzen is recycled, at last , more mesitylene is produced and the productive cost is much lower .

为此，本文将催化异构化技术和精密精馏技术结合起来，通过异构化将偏三甲苯转化为均三甲苯，通过精密精馏技术将产物中均三甲苯最大限度的分离出来，得到很高的产品纯度，同时偏三甲苯循环使用，提高了均三甲苯的产量，降低了均三甲苯的生产成本。

For the characteristics of closed chain with redundant coordinates, the Routh equation was applied to developing a dynamic model of the biped robot with heterogeneous legs to which the relationship between force and moment of the two legs are evaluated, thus giving dynamically the direct and inverse solutions to the Routh equation.

针对这一闭链并含冗余坐标的完整系统的特点，采用罗司方程建立了异构双腿行走机器人动力学模型，给出了异构双腿关节运动和力矩之间的关系以及动力学正逆问题的求解方法，并利用典型步态数据对所建模型进行了仿真计算。

The DFT (B3LYP/6-31 + G) method was used to study the relative stabilities and probable proton transfer in isolated and monohydrated 2,4-dithiothymine molecules in gas phase. The effects of water on relative stabilities and the rate of the proton transfer were analysed. The results indicate that only one tautomer for 2,4-dithiothymine can exist in gas phase.
