In this research a new mathematical model - cubic polynom with two given derivatives at end points - was proposed which can good match the S-shpae curve.This model has a number of analytical features:describing the geographic phinomena prosesses in three hierarchies (textural fractal,structural fractal and state fractal); the boundary values of the structural fractal can be considered as the boundary values of interval of scaleless.

在研究中提出了扩展分维表达函数：带导数三次多项式，它能很好地表达反S形分布曲线，具有一系列解析特征：可从三个层次（纹理分形、结构分形和态势分形）上描述地理现象或过程；其中结构分形的边界可近似地看作是非扩展分维无标度区的上下界。

The molecular weight dependence of the distribfition of polymer molecules between the coacervate and the dilute phases on the phase separation of polymethylmethacrylate-acetone-methanol system has been proved to follow the relation first derived by Flory for binary systems: f"_j/f′_j = Qe~_j where f"_j and f′_j are the weight fractions of the polymer molecules of molecular weight M_j in the coacervate and in the dilute phases respectively, while Q and σ are parameters.

1。聚甲基丙烯酸甲酯-丙酮-甲醇体系的两次分相实验用θ-溶剂中的沉降速度法测定分相前试样和浓相的分子量分布曲线，得到高分子在浓稀相重量分配的分子量依赖关系 f_j=Qe~证实Flory的溶度函数形式与实际相符，并适用于三元体系的相分离，但Q值与两相体积比R值并不相同。 2。再分级使级分的分子量分布宽度随再分级次数的增加而减小，通常认为到第三次再分级其效果已不显著并不确实。

In thisstudy, we sought to determine the number of injections neededto provide a reasonably complete anesthesia of the upper limbwith this approach. Seventy-five patients were randomly assignedto receive a coracoid block guided by nerve stimulator with42 mL of 1.5% mepivacaine with a single-injection (Group 1),dual-injection (Group 2), or triple-injection (Group 3) technique.

在本研究中，我们拟探讨为提供完善的上肢麻醉效果所需要的锁骨下臂丛神经阻滞的注射次数。75例病人用神经刺激器指导喙突旁臂丛神经阻滞，随机用1.5%的甲哌卡因42ml 行单次注射（组1）、分两次注射（组2）或分三次注射（组3）。

The first and secondary Hopf bifurcation and the chaos motion of the Langford system are controlled and the relationships between bifurcation parameter and control gains are obtained.

本文分别对Langford系统的一次Hopf分岔、二次Hopf分岔及其混沌运动的控制进行了研究，分别得到控制增益与分岔参数之间的解析关系。

I to you 1 see fall in love, in no way 2 heart, want to look after you 3 living 3 a life times, because I secretly top you of website 4 times, you be that 5 officers who is charmings, total let I 6 absolute beings be ownerless, a heart 7 top 8 times, 99 can't quell, if my full marks is 10 cent, you be certain and not only 11 cent, at least should also have 12 cent, can only cherish me to dislike 13 this numeral, otherwise you certain have 14 cent, if again plus you of cleverness that again not only 15 cent, 16 cent you certain still suspicion little, so I give you 17 cent.

我对你1见钟情，绝无2心，想照顾你3生3世，因为我偷偷上你的网站4次，你那迷人的5官，总让我6神无主，一颗心7上8下，99不能平息，如果我的满分是10分，你一定不止11分，起码也该有12分，只可惜我讨厌13这个数字，不然你一定有14分，如果再加上你的聪明那又不止15分，16分你一定还嫌少，所以我给了你17分。

Core of research this change one each into two each of bunch planting device, this is innovation in mentality of designing, and the sheave divides the opportunity question planted.

本研究的核心将穴播器的二次分种改变为一次分种，这是在设计思路方面的创新，以及槽轮分种的时机问题。

Methods From January 1988 to March 1999, 24 cases of congenital syndactyly were treated and classified by fusion tissue combined with the degree of fusion as follows:①simple complete syndactyly (4 cases).

结合并连的组织和程度分为：(1)单纯性完全性并指 4例，2指并指一次手术，3指并指分二次手术。(2 )单纯性不完全并指 9例，一次手术。(3 )复杂性完全并指 4例，分期手术。(4 )复杂性不完全并指 0例。(5 )复合性并指 7例，单纯行并指分指术。

Robinson Cano slugged a two-run homer and Johnny Damon worked a bases-loaded walk to open scoring in the second inning, and the Yankees added six more runs in the fourth with the benefit of two passed balls and a wild pitch.

洋基在2局下靠著 Robinson Cano 的2分全垒打和大门在满垒时选球眼的启动下打下3分。洋基之后又在第4局靠著2次捕役和1次暴投打下6分。

In Chapter 3, problems of cavitated bifurcation for a solid sphere composed of imperfect incompressible hyper-elastic materials, subjected to a surface tensile dead load, are examined.

证明了空穴分岔方程的平凡解支上存在唯一的分岔点；给出了左分岔和右分岔的判别条件，并指出了向左分岔的空穴分岔解还会发生二次转向点分岔。
