Using this model three competence-deficient pneumococci, which was identified by PCR and transformation experiment, were constructed. It is found different strain has different bacterial optimal density for being induced into competence. The optimal density for strains 1, 2 and 22 was 0.1, 0.08and 0.07 respectively. The optimal condition for transformation is c plus y culture at pH8.0. In c plus y culture at pH6.8, which restrained pneumococci forming transformation naturally, pneumococci could be induced to form transformation by CSP.It is concluded that we could induce different S.pneumoniae by CSP into competence in their optimal density in laboratory. 2. It was discussed the relationship between pneumococcal transformation formation and its opportunistic pathogenesis. Comparing their virulence with that of parental strains by challenging mice intraperitoneally and adhering to ECV-304 cell respectively.

结果表明不同肺炎链球菌株的转化最适菌密度不同，1、2和22号菌株的最适转化密度分别为0.1、0.08和0.07；用于转化的CTM培养基最适为pH 8.0的C+Y培养基；在自然转化下不能诱导转化发生的pH 6.8的C+Y培养基中，使用CSP诱导，也能促使细菌发生转化，只是转化效率较低；结论：实验室条件下，不同细菌在一定菌密度时可利用CSP诱导肺炎链球菌成为感受态发生转化。2、为探讨肺炎链球菌转化对毒力表达的影响，本研究分别通过体外粘附人脐静脉血管内皮细胞ECV-304和体内小鼠毒力实验观察1、2和22号肺炎链球菌和其转化缺陷菌株1t、2t和22t毒力的差异。

When two axes make the synchronized reverse rotation, on each instantaneous two axis eccentric qualities produce the centrifugal force of inertia, always mutually counterbalances along x-x force component, but always mutually superimposes along Y-Y force component, this has formed the sole this direction simple harmonics strength.

两轴作同步反向回转时，每一瞬时两轴上偏心质量所产生的离心惯性力，沿x-x方向的分力总是互相抵消，而沿Y-Y方向的分力总是相互叠加，这就形成了单一的该方向的简谐力。该力作用在筛箱上，驱动筛箱作轨迹为直线的往复振动。

An earlier idea of a skinned or fully faired Y-wing appeared in the Star Wars: Incredible Cross-Sections book from DK, but that design differs from the final look of the Y-wing bombers seen in this episode, which more effectively bridges the design aesthetic of the prequel and original trilogies.

DK出版社出版的《星球大战：机械图典》一书中，有个更早的想法是，Y翼呈现出一种蒙皮的或全流线型的外观，不过那种设计与本集中所见到的Y翼轰炸机的最终外观不同，后者更有效地将前传与原三部曲的设计美学连接起来。

The y and z-axes of ribbon correspond to the x and y-axes of plot.

该Y和Z轴的丝带对应的X和Y轴的阴谋。

The term z-map might be a little misleading to those who are not familiar to working in 3D space. In high school geometry class the concept of two-dimensional space: the x-axis represents horizontal space and the y-axis represents vertical space. Whenever you work in packages such as Painter, Photoshop, Commotion, Combustion or After Effects you are working solely in 2-dimensional space. When you work in 3D you have, in addition to the x- and y-axes, a z-axis, representing depth.

z-map这个称呼或许对那些不从事三维空间工作的人来说有一点误导的嫌疑，在高校的几何课里面，关于二维空间的概念，X轴代表着横向空间，而Y轴代表着纵向空间，无论何时你使用例如Painter， Photoshop， Commotion， Combustion 或After Effects这样的软件，你正工作在一个二维的空间，但是在三维空间工作时，除了X轴和Y周，你还要加上Z轴，它代表了深度的概念。

The Broms method, m method and p-y curve method are respectively used to calculate the horizontal resistance coefficient of the filled earth behind the abutment back wall, the m method and p-y curve method are used to calculate the resistance coefficients of the earth around the abutment column and at the sides of the abutment and pier piles. The TDV software is used to simulate the restraint of the earth to the piles ends.

The experiment results indicated that the comprehensive interaction mode of Y with DNA might be that the dibenzofuran ring of Y intercalated into DNA base pairs and the benzene ring in side chain bind to DNA in the groove.

以曙红Y为模型化合物，实验表明可能Y中的二苯并吡喃环嵌入了DNA的碱基对之间，其侧链的苯环键合在DNA的沟槽中。
