The study on the phylogenetic relations among these species is very useful for the study on genome and marker-assisted breeding in Brassica species. The karyotypic analysis is one of the most important methods in analysing the phylogenetic relation of species with closer relations. The protocol for inducing high frequency metaphase was established by pretreatment with low temperature and 8hydroxyquinoline, and then the preparation of chromosome and karyotypes analysis of six economical important Brassica species were carried out. According to the karyotypic analysis, it was shown that in the genomes of amphidiploid species, there are genomical components from didiploid species. Our result showed that B. campetris, B. juncea and B. napus belonged to class 2B, while B.

以二倍体B.nigra（B，n=8）基因组为探针，用B.campestris（A，n=10）或B.oleracea（C，n=9）的基因组进行封阻，分别与B.juncea（AB，n=18）和B.carinata（BC，n=17）进行GISH杂交发现，B.juncea和B.carinata基因组中仅有来自于B.nigra的8对染色体表现杂交信号，而其它染色体杂交信号较弱；以B.campestris或B.oleracea基因组为杂交探针与B.napus（AC，n=19）进行GISH杂交发现，所有19对染色体均出现杂交信号，根据杂交结果难以正确判断B.napus基因组中的哪些染色体是来自于A基因组，哪些是来自于C基因组；以rRNA基因（18S-5.8S-26S）为探针的FISH杂交结果表明，B.campestris基因组中rRNA基因位点为6对；B.oleracea为3对；B.nigra为2对；B.carinata为4对；B.juncea为6对；B.napus为6对。

This promotion of 360, must saying is brillant, the 360 one share flow that sold oneself give head of a station, stationmaster is met very of effort to 360 promotion, you see the promotion of red fox, you popularize a Google to give you how many money, the effect is to do not have however 360 a lot of better, the promotion of red fox compared with the promotion of 360 low is a class not just.

这个360的推广，不得不说是高明呀，360出卖了自己的一部分流量给站长，站长就会很努力的给360推广，你看火狐的推广，你推广一个google给你多少钱，效果却是没有360好很多，火狐的推广比起360的推广低的不仅仅是一个档次。

Now the structure has several fundamental characteristics as follows, the disparity of income within basic stratum appears remarkably widen, not only takes among different trades, but also between leaders and the be-managed; the disparity of income between white-collar and blue-collar tends to reasonable in balance; although the disparity of labors' income in different proprietorship takes on some widening, evidence in the mass is not obvious, except labors' income in collective enterprise is relatively low; owing to "non-position income" of partial labors having an increasing proportional to "position income", the disparity of real income grows more serious; peasants having moved into city locate in the lowest class of urban income structure; polarization between the have and the have-not just comes, and so on.

当前城市居民的收入分配结构体现如下几个基本特点，即计划经济时期的基本社会阶层内部的收入分配差距显著扩大，不仅表现在不同行业之间，而且更表现为管理层与被管理层之间的收入分配差距显著扩大；脑力劳动者与体力劳动者之间的收入分配差距总体上趋向正常、合理；不同所有制职工之间的收入分配差距虽有所扩大，但除集体单位职工收入水平相对较低外，总体意义上并不明显；部分职工"非岗位收入"占"岗位收入"的比重增大，城市居民之间实际的收入分配差距更大；进城农民总体而言在城市居民收入分配结构中处于最低层；整体意义上城市居民的收入差距明显，贫富分化的格局初现。

The chemical constituents of Huperzia serrata Trev. are mainly flavonoids, triterpenoids and alkaloids. In order to get further comprehension of lycopodium alkaloids, we studied the low-polar section of the alkaloids extraction of Huperzia serrata and 19 alkaloids were isolated by ways of silica gel, RP-18 and Sephadex LH-20 etc. All of their structures, including five new compounds and two known ones that were firstly found from this genus, were elucidated with the help of Mass, IR, NMR spectra and so on. The five new alkaloids (HS-07, HS-08, HS-09, HS-10 and HS-11) are belonged to lycopodine class. The other two ones that were new to this genus (HS-18 and HS-19) are belonged to miscellaneous group.

Using the concept of Boolean functions and combinatorics theory comprehensively, we investigate the construction on annihilators of Boolean functions and the algebraic immunity of symmetric Boolean functions in cryptography:Firstly, we introduce two methods of constructing the annihilators of Boolean functions, Construction I makes annihilators based on the minor term expression of Boolean function, meanwhile we get a way to judge whether a Boolean function has low degree annihilators by feature matrix. In Construction II, we use the subfunctions to construct annihilators, we also apply Construction II to LILI-128 and Toyocrypt, and the attacking complexity is reduced greatly. We study the algebraic immunitiy of (5,1,3,12) rotation symmetric staturated best functions and a type of constructed functions, then we prove that a new class of functions are invariants of algebraic attacks, and this property is generalized in the end.Secondly, we present a construction on symmetric annihilators of symmetric Boolean functions.

本文主要利用布尔函数的相关概念并结合组合论的相关知识，对密码学中布尔函数的零化子构造问题以及对称布尔函数代数免疫性进行了研究，主要包括以下两方面的内容：首先，给出两种布尔函数零化子的构造方法，构造Ⅰ利用布尔函数的小项表示构造零化子，得到求布尔函数f代数次数≤d的零化子的算法，同时得到通过布尔函数的特征矩阵判断零化子的存在性：构造Ⅱ利用布尔函数退化后的子函数构造零化子，将此构造方法应用于LILI-128，Toyocrypt等流密码体制中，使得攻击的复杂度大大降低；通过研究(5，1，3，12)旋转对称饱和最优函数的代数免疫和一类构造函数的代数免疫，证明了一类函数为代数攻击不变量，并对此性质作了进一步推广。

Individuals who have a positive history but a negative skin test tolerate penicillin-class antibiotics as well as they tolerate other antibiotics, according to AAAAI literature. Although the skin test is as safe as skin testing for other allergens, a "very low rate of resensitization" will occur after skin testing and reuse of penicillin. The skin test exposes the patient to an amount of penicillin that consists of 1/5,000th of that in a typical prescription.
