查询词典 activation energy

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。

Results The activation of NF-κB, proliferation response, and expression of IL-4 and I L-5 mRNA and protein in T lymphocytes stimulated by PMA were significantly hig her than those of their blank control (P.01), while those indexes of T l ymphocytes stimulated by PMA and PDTC simultaneously were significantly lower th an those stimulated by PMA alone (P.01). The apoptotic index of T lympho cytes stimulated with PMA were significantly lower than that of their blank cont rol (P.01), and the apoptotic index of asthmatic guinea pig T lymphocytes stimulated with PMA and PDTC simultaneously were significantly higher than that stimulated by PMA alone (P.01). The significant positive correlations w ere found between the activation of NF-κB and the proliferation (r=0.64, P.001), and the expression of IL-4 and IL-5 mRNA and protein of T lymph ocytes, respectively (r=0.55-0.68, P.001). There was also signific ant negative correlation between the activation of NF-κB and apoptosis of T l ymphocytes (r=0.62, P.001). Conclusions NF-κB may participate in the signal conduction of PKC regulated proliferation, apoptosis and expression of IL-4 and IL-5 of T lymphocytes in asthma.

结果加入PMA培养的哮喘组T淋巴细胞NF-κB的活化、细胞增殖反应、IL-4和IL-5的mRNA和蛋白质的表达均显著高于其空白对照(P.01)，而同时加入PMA和PDTC培养的哮喘组T 淋巴细胞以上指标均显著低于只加入PMA培养的哮喘组T淋巴细胞(P.01)；加入PMA 培养的哮喘组T淋巴细胞的凋亡指数显著低于其空白对照(P.01)，而同时加入PMA 和PDTC培养的哮喘组T淋巴细胞凋亡指数显著高于只加入PMA培养的哮喘组T淋巴细胞(P 。01)。T淋巴细胞NF-κB的活化与增殖反应呈显著正相关(r=0.64，P.00 1)，与IL-4和IL-5的mRNA和蛋白质的表达也均呈显著正相关(r=0.55-0.68，P 。001)，而与凋亡指数呈显著负相关(r=-0.62，P.001)。

PCF significantly abolished activation of JNKs and p38 kinase activation while enhanced ERKs activation.

PCF还能提高磷酸化ERK的活性但降低磷酸化JNK及磷酸化P38的活性。

RESULTS: Analysis of T cell activation in vitro revealed that preincubation of PBMC with 100 μmol/L gossypol could completely inhibit the expression of early activation marker CD69 on CD3+ T cells in response to 10 mg/L PHA, and block T cell activation by 10-7 mol/L PDB as well.

结果： 100 μmol/L的棉酚预先与T细胞温育，能完全抑制10 mg/L植物血凝素刺激的CD3＋T细胞活化抗原CD69的表达，又可阻断10－7 mol/L佛波醇酯对T细胞的活化作用。

Characters of various brain areas: In ADHD without Ritalin, the prefrontal lobe , basal ganglia , cerebellum, anterior cingulate gyrus , cerebellum and right inferior parietal lobulus showed lower activation than that of controls on IC. On IC in ADHD without Ritalin, activation of PFL remained lower than that in controls, GaC was similarly activated to that in controls. But on IC in ADHD without Ritalin, the activation of BG, cerebellum and right LPI was higher than that in controls.

不同脑区激活特点：ADHD患儿完成冲突任务时前额叶、基底节、小脑以及右侧顶下小叶激活程度低于对照组；完成中性任务时，前额叶激活程度较对照组弱，扣带回前部激活程度与对照组相似，而基底节、小脑、右侧顶下小叶激活程度较对照组强。

Analysis also indicate that activation energy of degradation in compound-stabilizer systems are considerably greater than others, among these POM/COPA/EVOH48 has the highest activation energy reaching220.19 KJmol-1 in nitrogen which is three times the value of blank POM (77.74 KJmol-1), and 530.37 KJmol-1 in air which also exceeds the blank POM (354.59KJmol-1) by fifty percent.

分析结果还表明复合稳定剂体系的活化能要明显高于其它体系。

The new elucidation of distributed activation energy was given in which not only an analytic expression of activation energy was obtained for the first time,but also the theoretical proof of Miura′s integration method in DAEM model was realized.

对分布活化能模型进行了新的理论阐述，不仅给出了分布活化能模型中活化能项的解析表达式，得到了Miura积分法的理论证明，还系统研究了这一新的DAEM表述对焦油馏分模拟蒸馏二级反应体系的适用性。

The results show that the recrystallization activation energy of both materials is larger than that of aluminum self-diffusion activation energy.

结果表明，两种材料的再结晶激活能均大于纯Al的自扩散激活能，并且复合材料的再结晶激活能略大于铝合金基体的再结晶激活能。

Activation energy of deformation is close to self-diffusion activation energy of α-Fe grain boundary.

与α Fe晶界自扩散激活能接近。

Yet, at the temperature range of 700～750℃, the deformation activation energy was much higher than the self-diffusion activation energy of grain boundary.

在700-750℃，变形激活能远大于晶界自扩散激活能，位错运动是激活能升高的原因。

More direct, directer ; most direct, directest
