The interactions of dsDNA and ssDNA with two osmium complexes have been studied by surface electrochemical methods based on DNA modified electrode. It is found that both osmium complexes bond DNA with electrostatic interaction. And some thermodynamics and kinetics constants, such as bindind constant , ratio of binding constants K〓/K〓, limiting ratio K〓°/K〓°at zero ionic strength (μ＝0), free energy ΔG〓, dissociation rate constant k and binding site size s have been obtained.

研究发现两种锇配合物都是通过静电作用与DNA结合，并计算得到联吡啶锇和二氯菲咯啉锇与dsDNA和ssDNA相互作用的结合常数、结合常数比K〓／K〓、μ＝0时极限结合常数比K〓°／K〓°、结合自由能ΔG〓、解离速度常数k和结合位点数s等多个热力学和动力学参数。

Firstly, several kinds of schemes were proposed according to the design demand. The best scheme was chosen after analyzing and comparing the schemes. The robot's structure was designed with Pro/Engineer and AutoCAD software. Secondly, the kinematics analysis conducted, coordinate transformation matrix using D-H method was set up, and the kinematics equation direct solution and inverse solution was deduced. The manipulative interface about the kinematics equation direct solution and inverse solution was completed with VC++ and the velocity Jacobian of displacement matrix was constructed using differential transform method. In the process of the trajectory planning based on robot's kinematics analysis, I propone a method by which we can get middle nodal point with normalizing factor in order to simplify our searching for these middle nodal points. In addition, I give these middle nodal points with actual physics signification. For eliminating contradiction between real-time and accuracy, I bring forward separately limit of error and reversal interpolation method. For decreasing calculation quantity, we resort to tri-spline interpolation in the articulation space.We analyse the work range of the robot by resorting to graphic means.
