查询词典 B

The immune level tested in different time after injection with ginkgolic acids in sensitization mode showed that the expression of CD3〓 and CD4〓T lymphocytes increased, but CD8〓 was restrained, while the B lymphocytes was also increased. The results suggested that sensitivity was approved and T lymphocytes proliferation was induced, which strength cell immunity responsion, at the same time B lymphocytes was differentiated to IgE antibody-producing cells when contacted with ginkgolic acids as allergen.

大鼠经致敏方式接触银杏酸后，在不同时间的细胞免疫水平与体液免疫水平的研究结果表明，大鼠CD3〓及CD4〓T淋巴细胞的表达增加，而CD8〓T淋巴细胞的表达受到明显抑制，同时参与体液免疫的B淋巴细胞百分率呈增高趋势，提示银杏酸可能作为变应原使机体敏感性增强，诱导T细胞分裂增殖，增强细胞免疫应答，同时促进B细胞增殖分化成IgE抗体产生细胞。

In order to study function and molecular polymorphism of classⅡB gene in fish, we have isolated cDNAs encoding classⅡB from spleen cDNA library of red sea bream by using EST sequencing, and examined genomic organization, molecular polymorphism and expression of red sea bream classⅡB gene.

在所测序的11个不同的阳性克隆中，有4个不同的cDNA序列被鉴定出。另外，利用rsbMHC2b3'UTRN和rsbMHC2b3'UTRC为引物，扩增同一真鲷个体的3'UTR，有12个阳性克隆被测序，测序结果中有2个不同的序列被鉴定出，表明MHCⅡB基因至少存在两种不同的位点。

B-ISDN supports switched, semipermanent and permanent point-to-point and point-tomultipoint connections and provides on demand, reserved and permanent services. Connections in B-ISDN support both circuit mode and packet mode services of a monoand/or multi-media type and of connectionless or connection-oriented nature and in a bidirectional or unidirectional configuration.

B-ISDN支持可交换的、非永久性的以及永久性的点对点和一点对多点连接，同时提供按需的、预留的和永久的服务。B-ISDN内的连接支持单个和/或多个媒体类型电路模式和分组模式服务，以及无连接或面向连接性的电路模式和分组模式服务，并且采用双向或单向结构。

If b is the total area of the shaded parts, find the value of b .

b 是阴影部份之面积，求 b 的值。

Calcium carbonate and soluble glass and so on were confected as alkaline antifouling agent. The Infrared Spectrometry results showed that 2275-2250 cm~(-1) diagnostic absorb wave crest in part A and 3390-3200 cm~(-1) in part B and 1730 cm~(-1) in coating film strongly proved polymers reacted just as the reacting mechanism, that means polysiloxane which offer low-surface-energy property linked Polyurethane system by —OH groups reacting with —NCO groups. Relative molar mass of part A and part B was determined by Gel Permeation Chromatography and the results were appropriate. Surface-energy was determined and results were between 33.6-47.17 mN/m and it increased when alkaline antifouling agent was put into the coating. Alkaline antifouling agent was releasing steadily when the coating film was dipped in seawater. As time gone, the pH value of seawater was increasing. Solubility parameter and results showed that there was no corrasive phenomenon between the polyethylene strand and the coating.

红外光谱分析结果表明，出现在A组分中的2275～2250cm~(-1)处的异氰酸酯特征吸收峰、B组分中的3390～3200cm~(-1)处硅羟基的特征吸收峰及出现在固化后涂膜中的1730cm~(-1)处氨基甲酸酯基团的特征吸收峰证明了涂料成膜物质交联固化符合本文的设计要求，即赋予涂膜低表面能特性的有机硅组分通过—OH基团与—NCO基团的反应已经链接到聚氨酯体系中；凝胶渗透色谱结果表明，成膜物质的A、B组分均为低分子量，符合预聚物的要求；涂膜表面能的测算结果表明，涂膜的表面能在33.6～47.17mN／m之间；加入碱式防污剂后涂膜的表面能略有升高；碱式防污剂的释放平稳，随着涂膜在海水中浸泡时间的增长，pH值有增加的趋势；用溶解度参数原则来评价涂料与网绳的涂装，结果表明，本试验研制的防污涂料对聚乙烯网绳无溶蚀作用。

If you're going to argue that A causes B, and if you're going to play by the rules of sound reasoning, you have to show first that A comes before B.

如果你同意是A导致了B，并且你也想让这件事听上去很有道理，那么请先拿出A在B之前发生的证据。
