In recent years, much attention has been attracted to the 1D strong correlated system with two mechanisms of opening gaps. The models include:(1) the frustrated spin-Peieds system,(2) the 1D Hubbard model with a staggered potential,(3) the antiferromagnetic Heisenberg chain with Dzyaloshinskii—Moriya interaction,(4) the spontaneously dimerized s=1/2 antiferromagnetic chain in a staggered magnetic field.

特别是近年来，具有双能隙机制的一维强关联系统引起人们的关注，这些系统具体包括：（1）具有阻挫作用的Spin—Peierls系统；（2）电荷转移型Hubbard模型；（3）具有Dzyaloshinskii—Moriya作用的反铁磁海森堡链；（4）在交错势场中具有自发二聚化的S=1/2的反铁磁海森堡链。

By employing the Jordan-Wigner transformation and a modified mean field method, we are able to determine its ground-state quantum phase diagram approximately. The chapter IV is the main part of this Thesis. It contains the main innovations in our work. We propose and study in detail a S=1 Ising chain with the interplay of single-ion anisotropy and dimerization. The main results and innovations are the following: We show that the total number of the zero-component of spins at each site is a conserved quantity. This quantity, which may intuitively called as hole's quantum number, is hidden in the system. We show further that the hole's number in the ground-state is zero; By using the Jordan-Wigner transformation, we map this model onto a series of subsystems described by the spin 1/2 dimerized transverse Ising model. We solve the subsystems exactly, by presenting the exact wave functions and spectra;We show that this system exhibits a series of quantum phase transitions by varying the dimerization strength. We determine the quantum critical points exactly. We also show that the criticality is the same as that of the uniform S = 1/2 transverse Ising chain.

第四章是本文的重点及主要创新内容，我们具体研究了自旋为1的在横向单离子晶格场中的一维二聚化Ising链，我们得到的主要结果和创新之处是：(1)证明了这一模型具有一种隐藏的对称性，即自旋第三分量为零的格点数目是一个守恒量，并证明基态出现在空穴数目为零的子空间中；(2)利用Jordan-Wigner 变换将此模型变换到一系列自旋为1/2的横磁场中的二聚化Ising 模型，并给出了相应严格的波函数及能谱；(3)我们发现系统的基态随着二聚化强度的变化将呈现出一系列量子相变，我们得到了量子临界点的精确位置，并证明其临界性质与自旋为1/2的横磁场中的均匀Ising 链中的临界行为属于同一普适类。

The force is dominated by entropy force when the chain isdeformed less than 0.9 of the full-extended chain, while by enthalpy force. Theenthalpy force is contributed by the intro-molecular interaction. Bond stretchcontributes to the force more than bond angle bend. Torsion and VDW contributelittle to the force.3. The internal energy contribution to the elastic force It is in dispute that whether 〓 is dependent on the strain, and it is hard toresolve the problem using present elastic theories because they are athermal.

我们模拟了聚乙烯模型聚合物的SMFS，研究了链长、势能有效距离和温度对力谱的影响，探讨了力谱的本质问题，得到以下结果：改进的分子动力学方法可以很好的模拟聚合物的SMFS；SMFS是链段的性质而不是整个高分子链的性质，对于聚乙烯，该链段碳原子数目大于40；SMFS的本质是熵弹性，形变小于全伸直链的0.9时，力为熵弹力；形变超过全伸直链的0.9时，能弹力占主导地位，这种能弹力完全是分子内相互作用引起的，是由键伸缩和键角弯曲贡献的。3。
