As for a given automata,there exists three cases:for some state which did not being visited, for some state itself indeed being not reachable although it has been visited,for some state it is equivalent to other states though it can be reached to, in these three cases it is obviously redundant to construct these automata, and the only way for us is to delete,integrate and reduct these useless states in order to minimize the number of states.

对于一个给定的自动机，它的状态中有一些根本没有被访问过，有一些尽管被访问过，但是本身是不可达的，有一些状态尽管是可达的，但是在功能上却与另一些状态等价，这样的自动机在设计和应用中显然很累赘，可以将一些无用的状态删掉，将另外一些等价状态进行整合和约简，使之状态数达到极小。

Based on it, another sufficient condition on asymptotic stability undering the meaning of Lyapunov's is obtained via the method of equivalent transformation and equivalent system.

At length 50, we got 3 inequivalent extremal self-dual [50,25,10] codes.

将这个性质用在寻找长度为66的自对偶码，我们得到至少五十个对应於w2互不等价的极端自对偶[66，33，12]码与一个对应於w1，β=32的极端自对偶[66，33，12]码；用在寻找长度为50的自对偶码上，我们得到三个互不等价的极端自对偶[50，25，10]码。

Unlike the F test and t test for one exclusion, the LM test and F test will not be identical

只有一个约束时，F检验和t检验是等价的，然而LM检验和F检验并不等价。

Because the hardware and software may be implemented quickly if wechoose proper normal bases to represent finite fields. In this paper, we first introducesome basic definitions and facts on normal bases over finite fields, then extend theseresults to any Galois extension fields.

在这篇文章中，我们先介绍了有限域上的一些基本定义及关于正规基的相关结论，进而将域扩张到一般的伽罗瓦扩域中，得到了伽罗瓦扩域中正规基与其对偶基等价的充分必要条件，从而将有限域上正规基的等价条件推广到任意伽罗瓦扩域上。

Cynanchum Lingtai apricot production in the average weight 65 grams, the brightly-colored fruit, juicy rich, sweet-sour taste, sweet from the nucleolus, when the late Qing Dynasty famous Shaanxi, Gansu provinces, the Qing imperial court Tongzhi tribute for years.

灵台生产的牛心杏平均单果重65克，果实色泽鲜艳，汁多味浓，甜酸适口，离核仁甜，清末时就驰名陕、甘两省，清同治年间曾为朝廷贡品。

Chenopodium album,Solanum nigrum, and Amaranthus retroflexus were very susceptible to the herbicides. Polygonum persicaria and Abutilon theophrasti were relatively less susceptible to the herbicides, and Lycopersicon esculentum was not susceptible to it. The relationship between reduction rates of weed biomass and PPM values of weed leaves 2,4, and 6 days after treatment was established.
