活化

Activation energy: The difference in energy between that of the activated complex and that of reactants, the energy that must be supplied to the reactants before they can undergo transformation to product.

活化能：使低能分子达到活化状态所需要的能量。

This model was finely fitted by theexperimental results and was used to calculate the activation area,which was 0.127 〓/mol with little dependence of subphasetemperature. The positive activation area indicate that there is anincrease in area when the activated complex is formed, increasingthe surface pressure should decrease the rate constant and that theactivated complex is unimolecular in nature.

在一系列实验曲线的基础上，我们提出测量的面积变化应该由聚合中分子结构变化引起的急剧的瞬时面积变化与随后的与此面积变化相反的弛豫过程两部分组成，并据此提出一种反应动力学模型，此模型与实验结果相当吻合，此模型用于处理聚合速率的紫外光强依赖性，得到聚合速率常数近似与光强成二次幂指数关系；此模型也被用于计算活化面积，发现活化面积为〓，几乎与温度无关。

The activation energy of pyrolysis reaction decreases with the increase of catalyst polypropylene ratio from 0 to 30%.

当剂塑比从0增加到30％时，聚丙烯裂解的活化能呈现降低的趋势，特别当剂塑比为30％时，其活化能降低约50％。

The activation energy of chemical reacton and diffusion is obtained by fitting the experimental data.

通过对实验结果的拟和，得到了化学反应活化能和产物层扩散活化能。

Results and ConclusionThe study of time-efficacy relation expresses that after infusing the solution of Phyuanthus emblica Phyllanthus emblica, medicated serum in different time activates the spleen lymphocyte of small mice differently after the 30min but before 180min. During this period, on 2h the activation of the medicated serum is the most obvious. The quantity-efficacy relation research expresses that megadose promotes the propagate of the spleen lymphocyte of small mouse and activates the macrophage in the abdominal cavity more obviously. On the other hand, the small dosage influents the survival rate of the mouse S180 ascites tumor cell more obviously.

结果与结论时效关系研究表明，用余甘子冻干粉溶液灌胃后30～180 min内不同时相含药血清对小鼠脾淋巴细胞具有活化作用，并在给药2 h时实验血清活化作用明显；量效关系研究表明，余甘子大剂量组实验血清对促进小鼠脾淋巴细胞增殖，促进小鼠腹腔巨噬细胞细胞活化作用以及小剂量组实验血清对小鼠S180腹水肿瘤细胞存活率的影响均具显著差异性。

Baicalin could inhibit the initial-period and mid-period activation of mouse T lymphocytes stimulated by Con A or PDB,which suggests that baicalin have the inhibitory effect on signaling pathway of T lymphocytes activation and be a potential effective immunoinhibitory agent.

结论黄芩苷能够明显抑制多克隆刺激剂Con A或PDB诱导的T细胞早期和中期活化，且呈明显的量效关系。提示黄芩苷在T细胞活化过程的信号转导中有抑制作用，从而可以通过抑制T淋巴细胞的活化，发挥免疫抑制作用，是一种潜在的免疫抑制剂。

In response to TCDD exposure, AhR nuclear translocator forms a heterodimer with the aryl hydrocarbon receptor after the ligand-dependent translocation of AhR to the nucleus, and eventually the complex binds to the xenobiotic response elements, which promote transcription of several specific genes, such as CYP1A1.However, the diverse effects of TCDD could not be simply explained by the AhR pathway.

对於戴奥辛的毒性机制，以往的研究认为与芳香基碳氢化合物受体（arylhydrocarbon receptor－AhR）的活化有关；TCDD 活化了AhR，被活化的AhR 从细胞质转移到细胞核内，在细胞核与另一个蛋白质AhR nuclear translocator形成二聚体，并与DNA 上的xenobiotic regulatory element结合，诱发某些基因（如：CYP1A1）的转译与表现；不过，单从AhR的代谢途径并不能解释所有生物上的毒性现象。

For the purpose of studying the effect of different activation and pyrogenation conditions on the porosity of carbon produced from waste tyre rubber pyrolysed in the pilot-scale rotary kiln pyrolyzer, a activation furnace was designed in which the tyre carbons was activated.

为了研究不同热解工况和活化工况对废轮胎活化炭品质的影响，运用自行设计的活化炉对废轮胎热解炭进行了活化实验。

In electroplating aluminum on NdFeB magnet with use of AlCl3-MEIC room temperature melt salt bath,said magnet is activated to improve deposit adhesion by carrying out.before plating,electrolysis on said magnet.and plating process was described as below:Toasting and degreasing ?Sand blasting Drying Electricity activating?ElectroplatingSolvent washing Water washing Drying

5利用室温熔盐电解质作活化液对钕铁硼磁体进行电活化处理，可以提高基体和镀层的结合力，并提出如F电镀工艺流程：烘烤除油→喷砂除锈→干燥→电活化→电镀→溶剂洗→水洗→干燥

The enhancement was thus explained by the formation of continuous improved epi-like Si microstructures with reduced grain defects and with a barely increased number of interface defects over the entire channel/junction. The hole-mobility in such laser-activated devices was as high as 403 cm2/V.s – doubles that of thermally activated devices.

电特性效能的提升在於侧向活化可以连续修补汲/源极与通道之介面，雷射活化能量亦可以降低通道缺陷密度且几乎不增加表面缺陷密度，因此本研究也获得超高之P型电晶体迁移率达403cm2/Vs，为传统快速热退火活化之两倍大。

With Death guitarist Schuldiner adopting vocal duties, the band made a major impact on the scene.

随着死亡的吉他手Schuldiner接受主唱的职务，乐队在现实中树立了重要的影响。

But he could still end up breakfasting on Swiss-government issue muesli because all six are accused of nicking around 45 million pounds they should have paid to FIFA.

不过他最后仍有可能沦为瑞士政府&议事餐桌&上的一道早餐，因为这所有六个人都被指控把本应支付给国际足联的大约4500万英镑骗了个精光。
