激活

Activates or deactivates contextual help relating to objects .

激活或取消激活物品相关的上下文帮助。

Under current-clamp mode,'depolarizing sag'was observed in all neurons with Ih current.

激活时间常数τ与神经元的大小负相关，也就是说大细胞上的Ih电流的激活速率要比小细胞上的快。

I〓 was activated when the depolarizing command was positive to -50mv and it's activation and inactivation time constant were 28ms and 60-90ms respectively.

I〓在去极化大于-50mv被激活，激活时间常数是2.0-8.0ms，有电压依赖性。

Epigenetic regulation is the mechanism by which gene function is selectively activated or inactivated in the cells.

表观调控是细胞中基因功能被选择激活或非激活的机制。

The results showed as:(1)Gegen decreases fasting insulin and insulin resistance index and increases insulin sensitive index of rats of insulin resistance induced by dexamethasone significantly;(2)Gegen can improve glucose tolerance of rats of insulin resistance but not to alloxan indued diabetes mice;(3)Gegen increases glucose intake of 3T3-L1 adipocytes and improves the insulin resistance of 3T3-L1 adipocytes induced by dexamethasone significantly;(4)Gegen can activate peroxisome proliferator- activated receptor gamma, make it bind to PPAR response elements;(5)Gegen can up-regulate mRNA expression of PPAR v ,aP2 and adiponectin.

结果表明：①葛根显著降低地塞米松诱导的胰岛素抵抗大鼠血清胰岛素水平和胰岛素抵抗指数，升高胰岛素敏感指数，改善大鼠的胰岛素抵抗；②葛根显著改善胰岛素抵抗大鼠的糖耐量，但对四氧嘧啶糖尿病小鼠的糖耐量没有明显的作用；③葛根显著增加胰岛素抵抗3T3-L1脂肪细胞对葡萄糖的摄取，改善地塞米松诱导的3T3-L1脂肪细胞的胰岛素抵抗；④葛根能促进HepG2肝癌细胞过氧化物酶体增殖物激活受体γ与靶基因的特异DNA序列结合，对PPARγ及其下游基因的转录具有激活作用；⑤葛根能够促进PPARγ及其下游基因脂肪酸结合蛋白(aP2)、脂联素mRNA的表达。

Based on the relation betweenthe current density and the activation energy, the glass-phase exponent 〓the relaxation of current density in 〓times window, the criticalcurrent in a certain criterion of electric field as a function oftemparature infixed field or field in fixed temprature were calculated.

利用交流磁化率测量，得到了Hg-1201和Hg-1223样品的不可逆线，同时系统地研究了交变磁场频率和振幅对交流磁化率损耗峰的影响，并用非线性磁通扩散的模型解释了这些实验结果，从中推得与温度、直流场和电流密度有关的磁通跳跃激活能，由与电流密度有关的激活能推出描述玻璃相的指数μ，在10-5秒～10-2秒时间内的电流密度弛豫，E-j曲线，一定电场判据下的临界电流密度与磁场和温度的关系，从E-j曲线可以看出确实存在&零电阻电流&的玻璃相。

Following chemical activation, blastocysts rate of the treated oocytes was similar to untreated oocytes.8 Following fertilization, however, few oocytes inhibited with CHX developed into morulae/blastocysts, due to a high incidence of polyspermy.9 Cortical granule migration occurred during inhibition, but CHX inhibition impaired CG migration, significantly no oocytes inhibited by CHX completed CG migration after maturation.10 CHX inhibition had no effects onα-microtubles and microfilaments of goat oocytes.

抑制24h转为正常培养24h，不影响卵母细胞的成熟和孤雌激活能力，并且CHX抑制后再成熟的卵母细胞经孤雌激活发育到囊胚的比例与对照组卵母细胞相似。8、体外受精后，CHX抑制后再成熟卵母细胞的多精受精现象显著增加，发育到桑椹胚/囊胚的比例显著低于对照组。9、CHX抑制过程中皮质颗粒仍能发生迁移，但是CHX抑制会对皮质颗粒的迁移造成不可恢复的损伤，使再成熟的卵母细胞内皮质颗粒不能完全迁移。10、CHX抑制对山羊卵母细胞α-微管和微丝都没有影响，无论是抑制后处于生发泡期的卵母细胞，还是抑制后再成熟的卵母细胞，微管和微丝的分布都与对照卵母细胞相似。

Ethanol, ionophore A23187 and a single electrical stimulation could hardly activate the recently ovulated oocytes (12—13h after hCG) which could be activated by 6 pulses separated by 5—6 min.

用乙醇、钙离载体A23187及1次电刺激很难使刚排出不久的卵hCG后12—13h）激活。6次电刺激可使这部分卵激活。

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。

I moved it from the incubator and animated it before plunking it into the aquarium (the animation procedure can take minutes or hours depending on the computer).

我把它从孵化器里迁移出来，在把它扔进水族馆之前激活它的生命（激活程序可能需要几分钟或几小时，取决于电脑）。

In the negative and interrogative forms, of course, this is identical to the non-emphatic forms.

。但是，在否定句或疑问句里，这种带有"do"的方法表达的效果却没有什么强调的意思。

Go down on one's knees;kneel down

屈膝跪下。。。下跪祈祷
