The contemporary rap on Rosewall's backhand is that it was a slice, lacking the dipping topspin of his rival Rod Laver or the penetrating flatness of Jimmy Connors' superb drive.

那个时代对他反手的议论在于他的反手球总是又飘又薄，缺乏他对手罗德。拉沃尔那样下沉的上旋球或者吉米。康纳斯那样富有穿透力的平击球。

论文第一章我们首先简要叙述了一维反铁磁自旋系统的物理性质以及量子相变的背景和特点，回顾了一些实验、解析和数值计算结果。

The spin-1/2 dimerized antiferromagnetic system is related to spin-Peierls tran-sition.There are still some discrepancy on the behavior of the ground energy densityand energy gap,such as pure power-law,logarithmic correction to the pure power-law in the uniform,integer powers in the dimerized limit,etc.

自旋S-1/2的二聚化反铁磁链与spin-Peierls相变有关，在对其基态能和激发能隙的临界行为描述上仍存在一些不完全一致的观点：如均匀极限的纯幂级数律，纯幂级数律的对数修正；二聚化极限的整数幂级数行为等。

But because difference among the predictions of different theoritical models in low z region is small, it is hard to tell us which model is more compatible with the experimental result. Our results from high z binning show a good consistence with the predictions based on z-dependence SU (3) asymmetry, quark-Diquark and pQCD model, which indicate the ud quarks in Λ hyperons provide contributions as well as s quark and the contribution is the function of z.

高z区间分法下归一法和螺旋度平衡法的分析结果显示同z依赖的SU（3）对称模型、夸克--反夸克模型和pQCD模型预言的纵向自旋转移值S〓和z的关系较一致，从而表明Λ超子中u夸克不但对Λ的极化有贡献，而且其贡献和Λ携带的能量份额z有关系。

This is a new kind of photoinduced phenomenon and it is a one-photon process.(2)A bipolaron is split into two polarons by photoexcitation.This photoinduced splitting converts a charge carrier into two spin carriers.(3)When the hopping effect is included, the energy of a soliton-antisoliton pair can be lower than that of single polaron in conducting polymers with degenerate ground state.

这是一种新的单光子过程光致现象；（2）通过光激发，一个双极化子可以分裂成两个极化子，这种光致分裂效应将一个荷电载流子转换为两个自旋载流子；（3）对具有简并基态的导电聚合物，如果计及跃变常数的变化这一效应，孤子-反孤子对的能量可以低于单个极化子的能量。
