This thesis focuses on quantum Monte Carlo study on mixed spin chain with random bond.

本论文将应用量子蒙特卡罗模拟方法计算具有随机耦合强度的混合自旋链的能隙，序参数等物理量以及它们的热力学性质。

This article mainly discussed critical and magnetic properties in the system of mixed spin-1 and spin-1/2 BCM with bond dilution and random crystal field.

中文摘要：混合自旋BCM 的临界行为和磁学性质是本文重点讨论的内容，在本文中我们主要采用了键稀疏和随机晶场作用下混合自旋为1 和1/2 的BC模型，在有效场的框架内计算并讨论了三维简立方系统的临界行为和相关磁学性质。

In the framework of effective field theory, we have calculated the relation of Curie temperature and crystal field and discussed system's critical and related magnetic properties in the system of three-dimensional cubic lattice in the presence of bond dilution and random crystal field.

系统的居里温度随着晶场的增加而单调递减并且在相图中出现了三临界点，而键稀疏对三临界点有着明显的抑制作用，当键稀疏浓度降低到阈值pc 的时候系统将出现诱导磁有序，此时晶场浓度无论如何取值，该系统在一定的晶场范围内 0 ≤？

Degradation products were investigated by Fourier transform infrared spectroscopy and its molecular weight was measured by the viscosity method. The results show that the mechanism of photolysis and hydrolysis of PLA is the same with the breakage of ester bond at random.

结果表明：PLA在紫外光解下的降解同水解一样都是酯键断裂导致的，并且是酯键的任意断裂；紫外光降解过程中，黏均相对分子质量的下降趋势先快后慢，并且PLA起始浓度越小越有利于降解。

The Dac model is easily described:choose a graph at random according to bond percolation,and then paint randomly and independently the different clusters,each cluster being monochromatic.We generalize the Dac model in the sense that the independent condition is weakened to uncorrelate.

第二章研究了Z~d上Bernoulli边渗流开簇的随机着色模型：按照Z~d上的边渗流机制随机的选择一个子图，然后给每个开簇上的点随机的染色，要保证这种不同的开簇上的染色行为是互不相关的，而且同一开簇上的点被染的颜色是相同的。

In the third chapter, it studies the base rate\'s change on the corporate bond market.

第三章研究基准利率变动对企业债市场的影响。

Nowadays, most of research are to build a transmutative Petri Nets through adding controlling place sets, controlling arc sets and controlling policy to the basic Petri Nets, while the Controlled Petri Nets could be used to argue many controlling theory problems conveniently and to induce many logically and physically supervisory and solve the Event Feedback Controlling Problems and State Feedback Controlling Problem in DEDS supervisory theory.

目前大多数的研究表现为在变形后的受控Petri网基础上，利用各种方法求得各种逻辑型、结构型控制器，解决DEDS监控理论中的事件反馈控制问题与状态反馈控制问题。
