In general, it was shown that the combinatorial vaccine with HBsAg and HBcAg can induce strong and homogenous humoral and cellular responses, and conduce to eliminate the endocellular HBV virus and break immunologic tolerance which existed durative in chronic hepatitis B patients. So it can offer the new thought and theory foundation for the further study to exploit the Hepatitis therapeutic vaccine.

It is considered that combinatorial technique will revolutionarily improve the development of material science.

材料的组合技术发展始于1995年发表在Science上的工作，引起了广泛的关注，随即引发了组合材料研究的热潮。

In this dissertation, we mainly dicuss the applications of semidefinite programming in combinatorial optimization.

本论文主要讨论半定规划在组合优化问题里的应用。

Using semidefinite programming relaxation and randomized rounding, we give the corresponding polyniomal approximation algorithms for some NP-hard combinatorial optimization problems.

我们对于一些NP-难的组合优化问题，采用半定规划松弛和随机舍入的方法设计了多项式时间的近似算法，这些算法的性能比都是目前为止最好的结果。

The distribution property of combinatorial sequences is a basic problem in combinatorics. One of the most important properties is unimodality which includes unimodal, log-concave, log-convex and PF properties.

组合序列分布性质的研究是是组合数学中最原始最基本的问题之一，其中一类重要的分布性质是单峰型性质，包括单峰性、对数凹性、对数凸性和PF性质等。

Among them, one of the most promising seems to be Simulation Annealing that aims to reach the optimization of an objective function by physically analogizing to an annealing process of malerial at high temperature. This involves in a transformation of optimization of a function in continuous domain into a combinatorial optimization in discrete domain, as well as the proper choice of various control parameters such as temperature, iterative number etc.
