查询词典 activation radioactivation

As to the difficulty of simultaneous estimation for frequency factors (k_0) and activation energies as well as the difficulty of many parameters to be estimated at the same time, the activation energies of the same kind catalyst and empirical activation energies are adopted, hence the number of parameters is reduced to half.

所采用的简化处理方法大大降低了参数估计难度，但引入了误差并将累积到频率因子上。

Results In all 12 normal children, the blood oxygen level-dependent signal was negative, and the maximum response appeared to be located in the anterior and superior part of the calcarine fissure, which may correspond to the anterior region of the primary visual cortex. However, in 24 cases of PVL, no activated pixels in PVC in 4; weak and tiny activation in 6; deviated activation in 8; and both tiny and deviated activation in 3 cases.

结果：正常对照组的激活区位于原始视觉区，BOLD信号变化均为负值，在24名PVL患儿中，枕叶平均激活像素数目减少，4例在PVC区没有激活，6例激活区体积明显减小，7例激活区易位，另有3例激活区明显减小并易位。

4On the condition of unilateral holding load and enough high load levels, the activation pattern of the two lumbar muscles existed contralateral enhanced effect;(5)The back weigh loading had symmetrical effect for lumbar multifidus and erector spinae.(6)The left and right hand weight loading had the same effect in activation level; The lumbar muscles activation of went upstairs were higher than the plain and downstairs

在行走过程中，随着负荷等级的增加，竖脊肌收缩力增大，其AEMG值也相应增大；左手提与右手提对腰部两观察肌肉的激活程度具有同等效果；上楼时腰部竖脊肌、多裂肌的激活强度显著大于平地和下楼时的激活强度，而平地与下楼之间不存在差异。

In the experiment section, there"re three experiments investigating implicit attitude and dual-attitude model. In the first experiment, the author studies the effects of attitude strengthen on attitude"s automatic activation effect. In the second experiment , the author studies the effect of delay condition on the attitude"s automatic activation effect. Delay condition make experiment approach to mere exposure of attitude object, and two experiment demonstrate attitude"s automatic activation effect is the result of noncognitive processing.

第一个实验，探讨了态度强度对态度自动激活效应范式的影响，结果发现态度强度不是影响态度自动激活效应的因素；在第二个实验中，探讨了时距对态度自动激活效应的影响，时距控制使得实验更接近于态度物的单纯呈现，结果发现时距没有对自动态度激活效应产生影响，从而论证自动态度激活效应可能是非认知系统作用的结果，具有普遍性。

This experiment aimed to systematically investigate and analyze the ethanol activated rates of mouse oocytes, affected factors of oocytes activation, types and development of parthenotes, and the organization and roles of the cytoskeleton during pronuclear formation and migration and early embryo cleavage by ethanol activation of oocytes, embryo culture in vitro and immunofluorescence cyto-chemistry. The results:(1) The ethanol activation of mouse oocytes showed that the activated and developmental rates of oocytes increased significantly with the increase of ethanol concentration and extension of exposure time, but over concentration and exposure time would result in increased fragment rates significantly. 7% ethanol treated oocytes for 7min was the optimum activated condition.

本实验主要利用卵母细胞的乙醇激活、胚胎体外培养和免疫荧光细胞化学方法对小鼠卵母细胞乙醇激活效率、影响因素、孤雌胚类型、发育、原核形成、迁移及早期胚胎卵裂过程中细胞骨架的组装、作用等进行了系统的研究和分析，结果显示：(1)小鼠卵母细胞的乙醇激活结果表明，随着乙醇浓度的升高和作用时间的延长，卵母细胞激活率和发育率都显著提高，但乙醇浓度过高和作用时间过长会导致卵母细胞碎裂率的显著增加，7%乙醇作用卵母细胞7min 为最佳激活条件。

Our results indicate that 1 NSC606985, at nanomolar level, can effectively induce apoptosis in AML cells NB4 and U937 and significantly inhibit the proliferation without cell death in breakpoint cluster region–Abelson murine leukemia kinase-carrying leukemic K562 cells; 2 At such low concentrations, this agent also significantly inhibits the clonogenic activity of hematopoietic progenitors from patients with AML; 3 For apoptosis induction, NSC606985 rapidly induces the proteolytic activation of protein kinase Cδ with loss of mitochondrial transmembrane potential and caspase-3 activation; 4 Co-treatment with rottlerin, a PKCδ-specific inhibitor, completely blocks NSC606985-induced mitochondrial m loss and caspase-3 activation, while the

结果显示：(1)纳摩尔浓度的NSC606985即可有效诱导AML细胞系NB4和U937细胞凋亡并显著抑制含有bcr-abl融合蛋白激酶的K562细胞的增殖；(2)低浓度的NSC606985也显著抑制来自AML病人骨髓的新鲜白血病细胞的克隆形成能力；(3)除了迅速诱导线粒体跨膜电位的崩塌及Caspase-3的活化外，NSC60698也导致蛋白激酶Cδ的水解激活；(4)PKCδ特异的抑制剂rottlerin能够完全抑制NSC606985诱导的线粒体跨膜电位的崩塌和Caspase-3的活化，而Caspase-3特异的抑制剂z-DEVD-fmk仅能部分削弱PKCδ的活化及细胞的凋亡；(5)以移植PML-RARα转基因小鼠产生的白血病细胞建立的模型研究了该化合物对白血病可能的治疗作用。

Taken together, our data showed that both the CSF-box and the octamer are important for the LPS-induced G-CSF promoter activity, moreover, the activation of MEK/ERK signaling pathway is indispensible for LPS-induced G-CSF expression in RAW264.7 macrophage.. It seems that LPS-induced activation of MEK/ERK pathway does not directly regulates NF-κB transactivity, but is essential for LPS-induced Oct-2 binding to the octmaer within G-CSF promoter and transcription activation of the G-CSF expression.

透过这些结果，我们认为MEK/ERK pathway的确参与LPS活化G-CSF表现的过程，虽然MEK/ERK pathway都影响了CSF-box以及octamer对G-CSF启动子所贡献的活性，但似乎MEK/ERK pathway的下游并非直接影响NF-κB调控基因转录的活性，而主要是影响了Oct-2对G-CSF启动子的调控。

Among the three kinds of activation methods, electrical activation was the best with (67.75±1.03)% oocytes cleavage rate and (13.52±2.05)% morulae rate. The best parameters for electrical activation was 130 V/mm and 80 μs.

电激活比乙醇激活、A23187激活有更高的卵裂率(67.75±1.03)%和桑椹胚率(13.52±2.05)%，且差异显著(P.05)，最佳激活参数为130V/mm、80μs、一次脉冲激活。

Artificially induced a single 〓elevation could effectively drive the activation, in recently ovulated oocytes (12—13 h after hCG) however, a single Ca〓 increase was futile in initiation of activation and only repetitive 〓 rises were avalable, suggesting that the activation of recently ovulated oocytes requires oscillatory Ca〓 signals as occuring at fertilization.

只有诱导卵内Ca〓多次升高才能使之激活。提示：刚排出不久的卵激活象受精一样需要胞质Ca〓波动信号。

The research show that from anthracite, lean coal to bituminous, reaction rate become more and more large and ignition activation energy become more and more small; ignition activation energy falls and reaction rate increases as the volatile content increases;With the carbon content of dry ash-free basis increasing, ignition activation energy increases and reaction rate falls.

结果表明：从无烟煤，贫煤到烟煤，其反应速率越来越大，频率因子越来越小，着火活化能越来越低；挥发分增加，活化能减小，反应速率变大；干燥无灰基固定碳含量增加，着火活化能增加，反应速率减小。
