The abscissa of the concentration convergence equals to the changes in the desorbed free energy of 1mol pure organic solvent, while that of carbon number convergence equals to the negative free energy change of its end group of the homologue, when the concentration of organic solvent is one tenth in the mobile phase.

浓度收敛点的横坐标是1mol纯溶剂的解吸附自由能；而碳数收敛点的横坐标为当流动相中有机溶剂的浓度为纯有机溶剂浓度的十分之一时的同系物端基的保留自由能的负值。

Based on the sliding response theory of the free-standing equipment, the differential equation of motion of the free-standing equipment under seismic excitations is presented. The equation is solved by Runge-Kutta algorithm, therefore the absolute acceleration, relative velocity and relative displacement of the equipment can be obtained. The sequential coulomb friction model is applied to the analysis.

以前人研究建立的浮放设备滑移反应分析理论为基础，给出了浮放设备在水平和竖向地震输入下滑移反应运动微分方程，选取连续型的库仑摩擦力模型，采用Runge-Kutta法求解浮放设备地震滑移反应运动微分方程，可以得到浮放设备在地震作用下的绝对加速度、相对速度和相对位移反应时程。

The preparation method comprises monomer synthesis and polymer synthesis. The polymer synthesis is that cyclopentadienyl sodium monomer is added into metallic cobalt complex-triphenyl phosphorus cobalt chloride under strict oxygen-free and water-free conditions, and then double inner alkyne or outer alkyne conjugate monomer is added in, and after reaction, the precipitation, filtering, abstersion and vacuum-drying are carried out, the large molecules polymer containing cyclopentadienyl cobaltocenium organometallic cobalt is obtained.
