Then the coefficients of entrance region effect and the relations between them, and the flowbehaviour index n can be obtained by solving the energy integral equation. Under the assumption of the velocity distribution within boundary layer: f = 1-(1-η)n+1/n for example, co...

以边界层内幂律流体层流速度分布假设f=(1一η)~(n+1/n为特例，所求出的结果与文献[4]中的理论值和实验值比较表明，本文的计算是既简便又可靠的。

Parties were first partitioned to form a tree, then n representations from n nodes which were children nodes of the corresponding father node in the above level agree on a group key in this round by invoking the BCP scheme.

群内成员先进行树结构的划分，每n个节点作为相应上一级节点的孩子节点，n个节点分别选定代表，n个代表通过调用协议BCP协商密钥得到本轮即相应父亲节点的子密钥，重复进行上述过程最终可以得到群组密钥。

Results The serum antibody level reached to 0.71±0.08-0.77±0.06 after genetic vaccine pCD-HCV1(100 μg/mouse) were inoculated into the mice(n=12) three or four times while blank vector pCD-SRα1 could not induce the mice(n=8) to generate antibody response in same way.After the antibody levels in mice(n=8) immunized by pCD-HCV1 had ascended to peak value(0.71), there was no trend of descending during the following 18 weeks of detection(0.68±0.06-0.75±0.07). Specific fragment of HCV cDNA identified by polymerase chain reaction from DNA extracted from the muscles of the mice after pCD-HCV1 had beed inoculated three months.

结果 基因疫苗pCD-HCV1(100 μg/只)3-4次接种小鼠后(n=12)，血清抗体水平达0.71±0.08-0.77±0.06，空载体pCD-SRα1免疫鼠血清抗体阴性；免疫鼠(n=8)抗体水平达高峰后(0.71)，持续检测18周未见下降趋势(0.68±0.06-0.75±0.07)；pCD-HCV1免疫小鼠3个月后，用聚合酶链反应仍可从肌肉组织中扩增出特异性HCV cDNA片段；免疫鼠PBMC对HCV合成肽CP9、基因重组抗原C、E1刺激后均出现增殖反应，刺激指数分别为4.07±1.58、3.88±0.70和3.69±1.30，与pCD-SRα1免疫鼠相比，差异有显著性(P.001)。

The first part is introduction in which some excellent results are given. For example, LeachandSholander mean of two variables E and its monotonicity, Some results of paper and [4] are also given. In Chapter l,mean function and mean family of n variables in one dimension are given. On the base of mean function of n variables of paper [1], weproof that is mean function and discuss its monotonicity andcontinuity.

第一部分是引言，主要介绍了一些已有的结果，如：一般的两个变元的Leach and Sholander均值B以及它的单调性，又介绍了文[1][4]中一些已有的结果，第一章主要介绍了一维n元平均函数和平均族，在已有的文[1]中给出的参差域K上的n元平均函数概念的基础上，证明一般形式的是平均函数，讨论了它的单调性和连续性，其中还将已有的二元Stolarsky平均推广到了n元平均。

If the infimum of sectional curvature R_c in M~n satisfies: then M~n must be totally geodesic in M~,T_c is the supremum of Ricci curvature and t_c is the infimum of Ricci curvature in M~

如果M~n的截面曲率下确界R_c满足：则M~n一定是全测地的其中T_c，t_c分别是M~(n+p上Ricci曲率上确界和下确界。

Equivalently, it can be raised as follows: for an A operator T, if M and N are two invariant subspaces of T satisfying N include M and dimN/M=∞, then does there exist another invariant subspace L such that N include L, and L include M ? It is rather difficult to study the invariant subspace problem of general diagonal operators.

研究表明它可以约化为对角算子的不变子空间的情形，具体地它有如下的等价提法：对于A算子算T，，如果M和N是T的两个不变子空间，满足且dimN/M=∞，那么是否存在T的另一个不变子空间L使得M包含于L，且L包含于N？

A selective and mild PS-DIB/ionic-liquid immobilized TEMPO catalytic oxidation procedure of alcohols to the corresponding aldehydes and ketones in ionic liquid BF4 at room temperature was developed. The oxidant PS-DIB was prepared via Iodation and acetylation of polystyrene resin. For the preparation of the ionic-liquid immobilized TEMPO catalyst, 4-(2,2,6,6-Tetramethyl-1-oxyl-4-piperidoxyl)butyl bromide was first synthesized from 2,2,6,6-tetramethyl-piperidin-4-ol-N-oxyl and 1,4-dibromobutane.

将聚苯乙烯树脂先碘化再乙酰基化，制得了负载型二乙酰氧碘苯(diacetoxyiodo polystyrene，PS-DIB)作为氧化剂。2，2，6，6-四甲基-N-氧自由基哌啶醇(2，2，6，6-tetramethyl-piperidin-4-ol-N-oxyl，TEMPO)与1，4-二溴丁烷反应生成4-溴丁氧基-2，2，6，6-四甲基-哌啶-1-氧化物，再与N-甲基咪唑发生季铵化反应，生成的溴化季铵盐与四氟硼酸钠进行离子交换制得氟硼酸型2，2，6，6-四甲基-N-氧自由基哌啶负载离子液体TEMPO-IL。

In group-V elements, the calculated acceptor ionization energy of N is 0.31 eV, which is much smaller than that of P (0.77 eV) and As (0.89 eV), and the acceptor formation energy of N is lowest among them.

在Ⅴ族元素当中，计算出N的受主电离能为0.31eV，远小于P(0.77eV)和As(0.89eV)，并且N的受主形成能在这三种元素当中也是最小的，因此可以说N是Ⅴ族元素中比较理想的p型掺杂元素。
