The result indicates that in the designed center of the wavelength, the retarder is not only confined within the low dispersive medium, but high-index material with higher dispersion can also obtain good achromatism, and at the same time the bigger angle of total reflection can improve achromatism of the phase retarder.
从全内反射相变方程出发,以菲涅尔菱体为例,分析了消色差相位延迟器的相位延迟量随折射率变化的光谱特性,结果表明:在所设计的中心波长处,延迟器件不仅仅局限于选择低色散的材料,色散较大的高折射率材料制作的延迟器件也可以具有良好的消色差性,且较大的全内反射角有利于改善延迟器件的消色差性。

Based on the laminate theory, a laminate weakened by damage is treated as an anisotropic thin plate. Using the complex potential method in the plane theory of elasticity of an anisotropic body, the series solution of finite anisotropic thin plate containing an elliptical inclusion is proposed with the help of Faber series. A hybrid element with an elliptical inclusion for anisotropic materials is obtained by using the hybrid variable principle, and the element efficiency is verified by numerical examples. The state of the damage is modeled by an elliptical soft inclusion, and using the point stress criterion based on characteristic curve and Yamada-Sun etc. criteria, the prediction of the strength of a composite laminate with damage is set up. The effects of various parameters on the stress distribution and the residual strength of a composite laminate weakened by damage are detailedly studied.

Results as bellows: AtSIRT1 was located in Mitochondrial as hSIRT4 of human, and maybe take part in respiration and electron transformation chain, AtSIRT2 was located in nucleolus as hSIRT6 of human, maybe play important role in extend lifespan;mutation in AtSIRT1 leaded to cotyledon of plant turn to yellow and caused short life span. Mutation in AtSIRT2 could make the color of leaf turn to purple and accumulate a lot of anthocyanin;Sirtinol, a inhibitor of SIRT which did not cause the same model of the mutation of AtSIRT1 and AtSIRT2 indicated that the mechanism of Sirtinol was different from other organism;the structure of AtSIRT1 and AtSIRT2 were similar to other known Sir2, which indicated that they maybe have the same function;AtSIRT2 was overexpressed and its activity was detected.

Surface relief caused by the formation of lower bainite in an Fe-C-Si-Mn alloy has been investigated by STM. It was discovered that the subunit which is the lowest structural unit observed by TEM is actually made up of sub-subunits. The surface relief due to the formation of sub-subunit is tent-shaped, and of a non-IPS type, which indicates that the sub-subunit cannot be formed by shear. The height of relief is 60-140nm, and the maximum shape deformation is ca.

The results show that with the increase of deformation strains and thinning of Fe-Cr fibers, the saturation magnetization are about 140 A·m2/kg constantly, and the remanent magnetism and coercivity increase gradually.The magnetic properties of Fe-Cr fibers are invariant when the Fe-Cr fibers were preserved in absolute alcohol or air for more than 1 a. After Fe-Cr fibers heated in air at temperature higher than 300 ℃ for 1 h, the Fe-Cr fibers transform from ferromagnetic α-solution to paramagnetic2O3, and the saturation magnetization of samples decreases remarkably. With the increase of deformation strains, the thermal stability of thinner Fe-Cr fibers decreases.

The results show that the growth rate of tetrapod ZnO is controlled by spiral growth and its crystallization is via VLS model. The condensation of tiny zinc droplets in zinc vapor is the key factor of the formation of tetrapod ZnO. The growth steps are formed on the terminated faces as zinc diffuses outwards and the elongation of whiskers continues until zinc inside the droplets is depleted. VS crystallization, which has little effect on the elongation growth, takes place on side faces of the whiskers and consequently makes the whiskers radius increase.
结果表明: T-ZnO晶须的结晶作用是气-液-固方式,晶须生长受螺旋生长机理控制;锌蒸气中产生凝聚生长的锌液滴是制备T-ZnO晶须的关键,锌从液滴内向外扩散在晶须的端面产生生长台阶,随着液滴内的原子向外不断扩散,针体部分就不断地伸长生长,当液滴内的原子全部消耗尽时,晶须便不再发生轴向生长;气-固方式的作用主要是促进晶须棱面生长而使晶须变粗,对轴向生长几乎没有影响。
