Influence of dyeing process on single transmittance and degree of polarization was discussed.

探讨了染色工艺对偏振片单片透过率和偏振度的影响，并通过正交试验确定了最佳染色工艺。

Their electrochemical behaviors are similar to that of TTF, so they should be good donors for conducting materials. They are novel monosubstituted asymmetric TTF-π-A donor molecules with TTF cores, which should be good donors for molecular conductors or OFET potential application.2. The tuning of the charge-transfer of TTF-PEO by solvent was realized forming the mono- and dication complexes_2CuBr_4 (5) and_2(CuBr_4)_2·CH_2Cl_2·CH_3CN (6) in the triclinic Pīand the orthorhombic Pbca space group, respectively.

同时每种化合物均为单取代的非对称分子，因此该类化合物在非线性光学材料领域可能有潜在的应用。2、通过改变溶剂的方法方便地实现了调节TTF-PEO的电荷转移量为+1和+2，分别合成出化合物_2CuBr_4 (5)和_2(CuBr_4)_2·CH_2Cl_2·CH_3CN (6)，晶体结构分析表明它们分别属于三斜的Pī和正交的Pbca空间群。

The distribution of gear's contact stress, root stress, and contact engagement line in the engagement situation of gear pairs, were obtained on the base of explicit integration method. 3. Adopting the method of system matrix, the torsional vibration differential equation of general shafting was gained. The simple harmonic forms of excitation torque under the normal combustion or piston flameout of in-line engine and v-type engine were analysed. The decoupled algorithm of free vibration and forced vibration and the solution to the vibration damper's energy of resistance and the off-resonance calculation were studied. The sensitivity formulations of the natural frequency and vibration mode to physical parameters of system were derived by solving the eigenvalue problem. These sensitivity formulations provided the theoretical base for the dynamic modification of structure.

运用系统矩阵法建立了轴系的扭振微分方程，并对直列和V型发动机在正常发火和气缸熄火工况下的激振力矩进行了详细的简谐分析；基于精确方法推导了自由振动和强迫振动的解耦算法，给出了能量法计算中的减振器阻尼功求解和非共振计算方法；并研究了曲轴系扭振非线性分析中的变惯量问题，得到了单缸转动惯量的精确求解公式以及变惯量和固有频率的关系式；最后，从特征方程和振型正交性出发，推导了固有频率和振型对轴系转动惯量和刚度等物理参数的灵敏度，为扭振系统的结构动力学修改提供了理论基础。

Combined with the moisture in the air in the room temperature, it will produce interconnection and vulcanize into high performance elastomer.
