Fourthly, Broyden iterative method is studied to solve nonlinear equation with parameters and the existence and convergence theorem is also given.

第四章的主要结果：研究用Broyden迭代求解带参数非线性方程，在弱条件下给出Broyden迭代格式的存在性和收敛性定理。

A series of novel dendrons with 1,3,5-triazine structure were synthesized by convergent strategy using cyanuric chloride, p-hydroxyazobenzene,β-naphthol, 1-hydroxyanthraquinone, 3,5-dihydroxybenzyl. They were the first generation p-phenyl-azo-phenyloxy-terminated dendron G1.0, the first generation naphthyloxy-terminated dendron G1.0, the first generation naphthyloxy-terminated and 1-anthraquinonoxy-cored dendron G, and the second generation naphthyloxy-terminated dendron G2.0.

以对羟基偶氮苯、β-萘酚为端基，三聚氯氰、3，5-二羟基苄醇为支化单体，1-羟基蒽醌为核心，用收敛法合成了一系列新型结构的含均三嗪环的树枝块：第一代端基为偶氮苯的树枝块G1.0、端基为萘氧基的树枝块G1.0、端基为萘氧基、中心为蒽醌的树枝块G、第二代端基为萘氧基的树枝块G2.0。

Looking back the pioneering path of generations of GNERI staffs at the tough conditions, many of them are as vivid as if they were just occurred at yesterday, and are so amiable, respectable and memorable. After vicissitudes and hardship in the past 30 years, GNERI has been developing from a small to a big institute, from a domestic to an international institute, which accumulated the condensed devotement, passion and wisdom with the painstaking care, unremitting effort, continuous progress, industrious work attitude of generations of GNERI staffs. It is GNERI staffs depicted ups and downs of GNERI on their way to the sunny road with youth, determination and righteous ardour.

回首过去几代能源所人在十分艰苦条件下的创业历程，许多故事好像就发生在昨天一样历历在目，令人可亲、可敬而又难忘。30年沧桑砥砺，30年风雨兼程，能源所从无到有、从小到大、从国内到国际，渗透着几代能源所人殚精竭虑、自强不息、艰苦奋斗的心血、热情与智慧，用自己的青春、意志和热血谱写了能源所人阳光路上的风风雨雨。

But the firstling of an ass thou shalt redeem with a lamb: and if thou redeem him not, then shalt thou break his neck.

34：20 头生的驴、要用羊羔代赎、若不代赎、就要打折他的颈项。

And every firstling of an ass thou shalt redeem with a lamb; and if thou wilt not redeem it, then thou shalt break his neck: and all the firstborn of man among thy children shalt thou redeem.

13：13 凡头生的驴、你要用羊羔代赎、若不代赎、就要打折他的颈项。凡你儿子中头生的都要赎出来。

It is substituting the name of one thing for that of another with which it is closely associated .

借代，是用一种事物的名字代指与之密切关联的另一种事物或另一个词。

The sample can be admitted to the ion source only after it is completely vaporized, otherwise,the result of masurement will be severly distorted by fractional distillation.

用接近于待测样品中所含的卤代烃的杂质样品与纯净六氟化铀可配置出已知卤代烃含量的"杂质标样"。

About the existence of duadic codes, Ward and Zhu(1994) obtained necessary and sufficient conditions for existence of duadic abelian codes, Zhang(1997) gave the existent conditions for such codes by some parameters and obtained necessary and sufficient conditions for existence of central duadic group algebra codes.

对duadic群代数码的存在性问题，Ward和朱烈(1994)解决了域上duadic阿贝尔码存在性；张胜元(1997)年用参数形式给出更具体的判定条件和中心duadic群代数码存在的充分必要条件。

In this method,without depending upon small parameter,a trial function with possible unknowns is used as initial approximation,then a correction functional is constructed by means of a general Lagrange multiplier ,which can be identified via variational theory.

本文提出了一种求解非线性方程的迭代算法，它不依赖于小参数，是先给方程一个带待定函数的试函数作为初始近似解，然后用拉氏乘子法构造一个迭代公式。

To study numerical solution of the linear equations,the article presents direct method ,Jacobi iterate method and Gauss-seidel iterate method to approximately calculate,and has given its process in MATLAB.

为研究线性方程组的数值解，文章用直接解法、雅可比迭代法、高斯-赛德尔迭代法进行了近似计算，并给出在MATLAB中计算的程序。

With Death guitarist Schuldiner adopting vocal duties, the band made a major impact on the scene.

随着死亡的吉他手Schuldiner接受主唱的职务，乐队在现实中树立了重要的影响。

But he could still end up breakfasting on Swiss-government issue muesli because all six are accused of nicking around 45 million pounds they should have paid to FIFA.

不过他最后仍有可能沦为瑞士政府&议事餐桌&上的一道早餐，因为这所有六个人都被指控把本应支付给国际足联的大约4500万英镑骗了个精光。
