They were fighting, albeit discreetly, to open the intellectual world to the new science and to liberate intellectual life from ecclesiastical phi losophy and envisioned their work as contributing to the growth, not of phil osophy, but of research in mathematics and physics.

难句类型：复杂修饰、插入语、省略、抽象词解释：本句再一次出现两个and连接三个不属于同一层面的成分的情况：第一个and 连接两个并列的不定式，第二个and的级别较高，连接前后两个并列的句子，and之后相当于省略了主语they。

The main results are as following:(1) Arabidopsis in planta transformation were made by Agrobacterium tumefaciens carrying the activation tagging vector pSKI015 with herbicide-resistant Bar gene as a selective marker. About 12 000 independent transformant lines were acquired by the above method, from which two mutants related to plant defense response and development, asr1 (auxin and .salicylic acid responsive 1.) and dai1 (brought tolerant and obscisic acid insensitive 1) were isolated.

The human cartilages are composed of chondrocyte and extracellular matrix , the form of chondrocytes are hypertrophy and the quantity are less; the ECM of cartilage are compised of type Ⅱ collagen and proteoglycan. Articular cartilages are all hyaline with little fibers. Trauma and arthritis are the main cause of cartilage injury, the ommilayer injury ofcartilage can be recovered by marrow, but because of without stimulation mechanism, the new tissues are merely fibrocartilages, they can not be coincide with hyaline cartilage in menchanics; the purely damage of articular cartilage can not stimulate chondrocyte to regenerate because of without blood circulation, thus, the plerosis of articular catilage can not depend on the proliferation of local chondrocyte. Ever since, people tried their best to find a way to reconstruct articular cartilage.

中文题名人骨髓基质干细胞成软骨诱导及多孔复合材料作为细胞载体的体外实验研究副题名外文题名 Cartilage induction of human mesenchymal stem cells and experiment on compound porous materials as cells' scaffold in vitro 论文作者刘晓岚导师周江南学科专业外科学研究领域\研究方向学位级别博士学位授予单位中南大学学位授予日期2003 论文页码总数68页关键词骨组织工程软骨细胞骨髓基质干细胞壳聚糖高分子外消旋聚乳酸馆藏号BSLW /2003 /R68 /10 造成人体关节软骨损伤的原因主要为创伤和关节炎，关节软骨全层损伤可由于骨髓中间充质干细胞的高速增殖修复，但这种修复由于缺乏相应的刺激机制，只能形成纤维软骨，而不能形成符合关节生理、力学要求的透明软骨；单纯软骨部分损伤软骨组织内无血管，软骨细胞迁移迟缓，无法使损伤区域软骨细胞再生，因此，关节炎及关节创伤后的软骨修复不能依赖于软骨细胞的增殖和迁移。

Multitasking: About 2.5% of people can use a cellphone and drive without performing worse at either task, according to a study forthcoming in the Psychonomic Bulletin and Review. The participants, 200 college students, performed a math-and-memorization test and a driving simulation first as single tasks and then simultaneously.

一心多用：《心理计量学公告与评论》（Psychonomic Bulletin and Review）上即将发表的一项研究发现，大约有2.5%的人可以边打手机边开车，而且还能做到两不耽误。200名大学生参与者先是分别接受数学识记以及模拟驾驶的测试，然后又同时进行了两项测试。

In this respect there is a classical distinction between intention obliqua and intention recta, in short, a distinction (as an "ideal type") between a descriptive attitude and a problem-related attitude, that is: either regarding a text and its message as something factual that we may "have"(as a piece of knowledge, as it were) and that we may talk about to others (be it as teachers to the students or as students during an exam), or conceiving a text and its message as a challenge that we should try to assess actively and critically, taking its various validity-claims seriously.

这里有一个对间接意图和直接意图（intention oblique and intention recta）的经典区分，简单说，是对描述性态度和取向问题的态度间的区分，即：要么1）把文本及信息看成事实，是我们可以&拥有&的，可以向他人谈论的（如教师对学生谈论或考试中学生之间谈论的），要么2）把文本及信息看成一项挑战，我们应设法对其作出批判性的积极评价，认真对待其各种有效性主张。

The topological rearrangement operators often used in heuristics are Nearest Neighbor Interchange, Subtree Prune and Regraft and Tree Bisection and Reconnection, and TBR is the most exhaustive.

To investigate the possibility of such a transition, we studied 17 cases of MGA or atypical MGA some of which had given rise to carcinoma in situ and/or invasive ductal carcinoma using the reticulin stain, immunohistochemistry (S-100, p63, Ki-67, and p53), and a molecular approach involving microdissection and high-resolution comparative genomic hybridization and MYC chromogenic in situ hybridization.

为了研究这种转变的可能性，我们分析了17例典型或非典型的MGA，其中一些已经发展成为原位癌和/或浸润性导管癌，所用的方法是网状染色、免疫组化（S-100， p63， Ki-67， and p53）和分子技术，分子技术包括显微切割和高分辨率比较基因组杂交及MYC显色的原位杂交。

Northern blot analysis of iNOS expression and iNOS stability revealed that bismuth subgallate (100 μM) significantly reduced the amount of iNOS mRNA and increased iNOS mRNA degradation. Because expression of iNOS is mediated by transcription factor, NF-κB, in the transcriptional level and immunosuppressor, TGF-β, at the post-transcriptional level, we examined the effect of bismuth subgallate on TGF-β1 production and NF-κB activity.

在本实验中，我们发现仅bismuth subgallate会减少以interferon-γ and lipopolysaccharide活化之RAW 264.7 巨噬细胞株中一氧化氮之含量，我们进一步以北方墨点分析iNOS mRNA含量及iNOS mRNA稳定性，结果显示处理bismuth subgallate的活化巨噬细胞中，iNOS mRNA含量较未处理之细胞明显地减少约60%，其iNOS mRNA半衰期较未处理之细胞明显地减少约50%。
