Among of these, the research of TEHV has taken positive progress,but the research of EHT just started recently ,it is still facing a series of problem.At first,it is the selection of planting cells,how to take high degree of purity about cardiomyocytes should be overcome;Second,it is the selection of scaffolds,the biomechanical properties of scaffold been used still can,t meet the requirement.

首先是种子细胞的选择，如何获取纯度较高的心肌细胞，还需从各种种子细胞中进行筛选；其次是支架材料的选择，目前应用的材料在生物力学特性上还不能满足临床使用的要求，还无法承受左心室巨大压力的冲击，因此还有待进一步的研究和改进。

You will also choose two elective models, one of which may be from the alternative to your specialism.

您还将选择两个选修模式，其中之一可能是从您的专业选择。

In this thesis, we focus on the theory for the interaction of molecular dipole moment with external electric field and use the numerical simulation to investigate the rotational state-selection of polar molecules in a hexapole electric field and the laser-field role of alignment or orientation for molecules based on semi-classical treatment, the detail is the numerical calculation for a quantum mechanical treatment of molecules and their interaction with the external field and a classical electrodynamical treatment for static electric field.

本文研究是在描述分子偶极矩（永久偶极矩或诱导偶极矩）和外电场相互作用的基础上，我们建立了对分子态选择和角动量取向、准直研究的半经典理论框架（即分子体系状态、能量及与外场相互作用使用量子理论描述，分子的运动轨迹使用经典电动力学描述），并利用数值计算方法对静电场和随时间变化电场作用下分子的转动态选择、取向和准直过程进行了研究。

It has been well established that metals present in trace amount in raw materials have great influence not only on the anode quality but also on the performance of anodes in the electrolytic cell and on the quality of aluminum liquids.

测定了抚顺铝厂所用的4种炭电极原材料中铁、钙和镍的含量，结果表明，仅从铁、钙、镍三种微量元素含量的角度来选择原材料，辽阳3号延迟焦和改质沥青在提高产出铝的质量，降低阳极消耗方面来说是较好的选择。

This article first introduces the math foundation required by ECC,including the addition rule for elliptic curve point defined over finite field.Then , the principle of ECC is discussed and its security and efficiency of ECC are analyzed.Third, a cryptosystem is designed through analyzing the security requiration, choosing the elliptic curve domain parameters,denoting field element,elliptic curve and elliptic curve point,choosing associate primitves and schemes andpartitioning functional module.Forth, how to develop a crytosystem based on elliptic curve encryption algorithm is investigated.Fifth, a cryptosystem we have developed by us and the testing result is described.

本文首先介绍了ECC的数学基础，对有限域上椭圆曲线点的运算规则进行了详细描述；其次探讨了ECC的原理，分析了ECC的安全性和有效性；第三，设计了一个基于ECC的加密系统，包括系统的安全需求分析，域参数选择，域元、椭圆曲线、点的表示，原语和方案的选择，及整个系统的模块功能划分；第四，在设计的基础上，研究如何开发一个基于椭圆曲线的加密系统；第五，描述了一个我们已经设计与开发的基于椭圆曲线的加密系统，并给出了相应的测试结果。
