Objective The origin and the nature of the Hodgkin and Reed-Sternberg cell of Hodgkins lymphoma has been attracting a lot of medical researchers engaged in studying it,for its character by scattered large atypical cells residing in a complex admixture of inflammatory cells.Great improvement has been made since a new method of isolation of single H/RS cells from a frozen section had been set up by KUppers in 1994,and many studies have approved of the B-cell derivation of H/RS cell.lt has been reported that H/R-S cells might partly be originated from B-cell in our research before,but at the same time,we also found that only 18.8% of H/RS cells express CD20,31.3% of immunoglobulin heavy chain rearrangement have been revealed.

目的 霍奇金淋巴瘤(Hodgkins lymphoma，HL)由于它的恶性肿瘤细胞—H／RS细胞一般只占肿瘤组织的极少部分(不到1％)，且散在分布在背景细胞间，因此对于H／RS细胞的来源和性质研究一直是人们探索的目标。1994年德国科隆大学Kūppers等发展了一种从冰冻组织切片上用显微操作仪挑取单个H／RS细胞的显微切割方法进行H／RS细胞基因分析后，人们对H／RS细胞来源的研究有了突破性的进展，多数支持B细胞来源。

In Chapter 2, the D-symmetric solutions of matrix equation A~TXA = B on the linear manifold S ={X ∈ D~(-2)SR~|XZ = Y, Y = Y{D~2Z+D~2Z, Z~TD~2Y = Y~TD~2Z, Y,Z∈ R~}, by applying the generalized singular value decomposition of a matrix pair, the necessary and sufficient conditions for the existence and the expressions for the D-symmetric solutions of matrix equation A~TXA — B on the linear manifold are established.

运用矩阵对的广义奇异值分解，给出了这类线性流形上矩阵方程A~TXA=B存在D对称解的充要条件及其通解的表达式。另外给出了它的D对称最小二乘解的表达式。

The theoretical plasma concentration versus time was calculated for all patients on the basis of the pharmacokinetic models described by Sheiner et al. Predicted effect versus time was calculated by following the pharmacokinetic-pharmacodynamic link model. The Ke0 was estimated by fitting a sigmoid cure. Group B was given the drug in a bolus of 2 mg.kg-1 and the Ke0 was calculated according to the method reported by Minto et al.

22例ASA ⅠⅡ级择期手术患者，A组(n=11)持续输注罗库溴铵0.03 mg·kg-1·min-1直至4个成串刺激降至20% 30%，B组(n=11)单次注射罗库溴铵2 mg·kg-1.A组血浆药物浓度用Sheiner等报道的药代动力学参数模拟计算，预测效应根据药代动力学-药效学关系公式换算，Ke0通过S型曲线拟合计算。B组采用Minto等提出的方法计算。

Producing PHAs,and then were orientationally inserted into a prokaryotic expression vector pBV220. By analyzing the bioactibity and function of their products, the biological function of phaA, phaB and phaC was confirmed. These have been done in our laboratory. To make better use of the three genes by plant bioreactor, two groups of different plant expression vectors that can be used to produce PHAs in different plants were constructed, and the transformation of PHA in Oxalis triangnlaris has been preliminarily reseached.The following is the main results:Three plant expression vectors pBI121-A,pBI121-B and ubquiting-C, which can be used to be transformed into Oxalis triangularis were respectively constructed by using the phaA, phaB and phaC.

菌株的亚克隆基因组片段中，分离出phaA、phaB和phaC三个基因片段，定向克隆至原核表达载体pBV220，通过对其生物活性与功能分析，确证了基因phaA、phaB和phaC的生物学功能；为了通过植物生物反应器对这三个基因进一步研究利用，本实验利用这三个基因构建了两组可用于不同植物生产PHA的真核表达载体，并对紫叶酢浆草进行PHA基因遗传转化的初步研究，获得主要结果如下：利用克隆的phaA、phaB、phaC三个基因分别构建了可用于转化紫叶酢浆草表达载体pBI121-A、pBI121-B、uBquiting-C；可用于玉米转化的种子特异性表达载体p7S-A、pBI121-S-B、uBquiting-C。

B: It's the best seller everone's been talking about for the last six months.A: How in the world did you get a copy? I've had a hold in at the public library for weeks, and I'm still waiting my turn.B: I checked it out of the rental library.

我在公共图书馆已经预约几个星期了，现在还在等着轮到我。B：我是在出租图书馆借到的，每天只要五分钱。A：它真是值得花钱去租来看吗？

On the basis of fully mastering the unity and utilize the contradictory movement of A and B, so that we can create a better mode and introduce striper impetus for social improvement /development.

总之，我们应理性地认识A与B的关系，在充分掌握A与B对立统一规律的基础上，科学地引导和利用AB的矛盾运动，以便为社会的进步创造更优的模式、倾注更强的动力。

On the basis of fully mastering the unity and the contradictory we can lead and utilize movement of A and B scientifically, so that we can create a better mode and introduce striper impetus for social improvement /development.

总之，我们应理性地认识A与B的关系，在充分掌握A与B对立统一规律的基础上，科学地引导和利用AB的矛盾运动，以便为社会的进步创造更优的模式、倾注更强的动力。

B。 分析：思路特点：注意空格后句中的词语使用特点：空格后面连续两句都涉及到了"suspension bridge/吊桥"因此判断空格处出现对"吊桥"进行讲述的句子的可能性最大，但被选项中没有该词出现，注意到空格后的句子中出现了代词They，该词的出现表明前面有复数的名词与之相呼应，而且They内容是指"桥"，因此排除A，C和E， F（没有与They呼应的内容），所以答案是B。
