The growth and nucleation rates of〓 cleavage face of YbYAB crystal are all very fast, because so many growth steps and growth centers were formed within only 2～3 second at the temperature near the saturate point. No spiral growth steps can be found, so growth mechanism is twodimensional nucleation. When the flux temperature increases for only 0.5℃ above the saturate point, the spiral melting holes are formed. The transformation from growth morphologies to melting morphologies is very sensitive to the temperature. When the temperature increases another 1℃, the spiral melting holes transform into two-dimensional nucleation melting holes.

YbYAB的〓解理面的生长及成核速度都非常快，在比饱和点低0.5～1℃的温度下，当生长2～3秒钟时，可以看到许多生长中心与生长台阶的形成，在较宽的台阶上还可以看到二维核的形成，没有看到螺旋中心，说明生长机理是二维成核生长；当温度比饱和点高0.5℃时，在〓解理面上形成螺旋状熔坑，这表明形貌由生长到熔化的转变与温度的关系是非常敏感的；当温度比饱和点高1.5℃时，螺旋状熔坑转变为二维成核状熔坑。

Although the spiral parts is widely used, there is very few studies on the spiral buries parts and in the vicinity of the stress and strain analysis, and when studies on the force, often approximates the spiral surface to the smooth surface in computing, or obtains through experiments.

虽然螺旋状预埋件的应用广泛，但是关于螺旋状预埋件及其周边的应力应变分析的定量分析在国内外的研究却很少，在研究时往往通过试验获得数据，然后进行定性分析，或者将其螺旋状的表面近似成光滑的表面进行计算。

In chapter 2,we establish theformulation of the extended mean-field theory that can be applied to cholesteric liquidcrystals,and we apply this extended mean-field theory to study the helical structure ofcholesteric liquid crystals.

在第二章中，我们将文献[6]中丝状液晶中的广义平均场方法推广到了螺旋状液晶体系，并用这一方法讨论了螺旋状液晶中分子指向矢的螺旋结构。

Based on membrane extraction and helical tube technique, the mass transfer performance of some membrane modules with a different helically wound hollow-fibre was studied with the system of 30%TBP-water and phenol as the solute. The effects of two phase flow rates, geometry of the membranes on mass transfer coefficients were investigated.

为了使这一广义平均场方法具有更广泛的适用性，使之也可以应用于结构比较复杂的螺旋状和层状液晶，在本文的第一部分，我们将文献[6]中陶瑞宝教授等提出的广义平均场方法作了形式推广，经过推广后的广义平均场方法也可以应用于螺旋状和层状液晶。
