通过比较四种均三氮苯类除草剂的红外光谱特征吸收的实验值和计算值，并运用规范不变原子轨道法GIAO法在RHF/6-31G水平上计算出西玛津的δ~1H-NMR和δ~(13)C-NMR，与实验值的对比统计分析，结果表明：用RHF/6-31G优化的分子构型最佳，AM1法次之，考虑到优化时间和研究的需要，我们在研究均三氮苯类除草剂分子的结构与活性关系时，为了进行深入、精确的理论研究，采用从头算RHF/6-31G进行优化；而对于此类化合物的结构与毒性的关系研究时，更注重分子的量子化学参数的相对值而非绝对值，因而采用AM1的方法。

Two GFRF system model identify algorithms based respectively on Signal Flow Graph/Driving Point Impedance and EDA simulation are proposed. In order to solve the problem of fault diagnosis that the inner structure and parameters of the Object under Test cannot be able to determine, a new fault diagnosis method based on the phase space reconstruction and GFRF general formula is investigated. This method builds up a bridge between the chaos theory and Volterra series analysis, which does not strongly depend on the topological structure and the testing data length, is sensitive to the fault property, traces monotonously the change of system fault, and possesses some significant predominance compared with conventional fault diagnosis methods of analog circuits.

In addition, the blank holding force that is required to avoid wrinkle and rupture during conical part deep drawing is researched. The necessity of reasonable blank holding force in pressing is expounded. From the view of mechanical analysis, the wrinkle critical condition of side-wall is derived for the first time by the stress state of side-wall, the main deformation region on blank. According to the critical condition of plastic instability for flange, side--wall, corner of punch on blank, The blank holding force in conical part deep drawing is divided into four different regions within its forming figure. The basic principle of reasonable blank holding force during stamping is summarized and provided. The mathematical model of reasonable blank holding force that avoids the wrinkle and rupture is established and verified by the finite element numerical simulation and the grid experiment method. The result shows that it is accurate and reliable.
