实验室实验

In this paper, the dissents in groundwater analytical data from a ministerial professional laboratory during 1991 to 2000 were summarized. The factors resulting in the dissents, their characteristics and causes, as well as prevention measures were discussed. During the 10 years, dissents of 12 parameters including H2SiO3, Sr, NO2(superscript -), I(superscript -), SO(superscript 2- subscript 4) and etc. were found and most of the parameters are very important in research of hydrogeology, hydro-geochemistry, groundwater environment and groundwater exploration.

通过对国土资源部某专业实验测试中心10年质量异议资料的分析，总结了地下水水质检测中容易产生质量异议的检测参数，分析了这些参数的特点，探讨了质量异议产生的原因和预防措施。1991~2000年间该实验室共有H2SiO3、Sr、NO2、I、SO(上标 2-下标 4)等12项检测参数出现质量异议，大多为水文地质、水文地球化学、地下水环境质量研究和地下水开发利用所关心的关键参数。

Experiment was not known to anybody at that time, but top CIA officials evinced great interest in it.

像这样处理过的水，还在高度保密的情况下被分别送往其他实验室，而所有的实验结果都必须直接送给当时的CIA局长约翰。

This paper pointed out the meaning of opening laboratory, and expatiated the construction of the mode.

本文指出了实验室开放的意义，阐述了开放式实验教学模式的构建。

This is one of the experiments being carried on in our laboratory.

这是我们实验室里正在进行的实验之一。

The construction and development of laboratories are directly related to the quality of experimental practices and researches.

实验室的建设与发展，直接影响着实验教学和科研任务的完成。

But now imagine a medical lab technician who overestimates his ability to interpret the results of a lab test.

D：是的。但是现在想象一个医学实验室的技术员过高的评价自己分析一个实验结果的能力。

As determined by SDS-PAGE and dcnsitometry, the overproduced proteins comprised up to 18.5% of the total bacterial protein.

通过SDS聚丙烯酰胺凝胶电泳检测表明，在实验室规模的发酵实验中，NAP-1/IL-8在大肠杆菌中的表达量可占菌体可溶性蛋白的10.9％；而在摇瓶培养中则占18.5％。

The measurements and simulations are performed in real labs. Before the simulations, the size, structures and layout of labs are determined, specially, including the permittivities of materials in labs.

在实际实验室内进行仿真和测量，仿真前对实验室房间的尺寸、结构、内部布局都进行了认真的测定，特别是对每种物体在仿真频率上的介电常数进行了认真的测定。

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。

The split between the two groups can hardly be papered over.

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
