成熟胞质的活化与卵母细胞相似，在活化后MAPK被迅速灭活，只是胞质在活化处理后均发生碎裂，而卵母细胞活化后形成原核，这表明核在细胞形态维持中起重要作用。

MMPs are usually secreted as latent, inactive proenzymes, which need to be activated (Fig 1 ), and/or are bound to their native inhibitors, the tissue inhibitors of metalloproteinases.8 Activation may involve proteolysis and/or oxidation of the latent enzyme.8 Proteolytic activation of the proenzymes cleaves the propeptide sequence, which masks the active site of the latent enzyme.

金属蛋白酶常以无活性的酶原方式分泌，而后者要么需要被激活要么与附近的或组织中金属蛋白酶抑制物结合。激活作用包括了具有潜在酶的蛋白水解作用或氧化作用。酶原的蛋白水解激活作用能将掩盖活性部位的潜在酶的前肽序列破坏。

To estimate the activation energy of the decomposition, the Friedman isoconversional method was applied. The activation energy was calculated as a function of conversion. The results confirm that more than one reaction occurs in the decomposition of basic zinc carbonate.

采用Friedman法对实验数据进行分析，结果表明，反应的活化能数值随着分解率的不同而变化，由此推断该反应是由多步反应组合而成的，其平均表观活化能E。

Voice activation is perfect for placing a call; opening the flip lid on a phone is probably the most effective way of answering it (or again using voice activation for hands-free use).

语音激活来打电话就非常理想，打开翻盖手机的盖子来接电话无疑也是最有效的接电话的方式之一，或者用语音激活免提功能。

The results show that the rudder angle of torpedo, the battery activation time, and the initial velocity of torpedo all affect the trajectory of torpedo. The rudder angle ought to be set positive when torpedo is launched downwards,or set negative when torpedo is launched upwards to gain perfect trajectory. Meanwhile, shorter battery activation time and higher initial velocity of torpedo are necessary.

结果表明，以上3个参数对鱼雷弹道都有影响，由小深度向大深度发射鱼雷时，横舵管制舵角应设为正值，由大深度向小深度发射鱼雷时，横舵管制舵角应设为负值，并尽量缩短动力电池激活时间，提高鱼雷出管速度，电动力鱼雷管外激活发射可获得较好的弹道。

The P wave duration and P 2R interval were increased while pacing at right atrial appendage 1 The activation time from pacing site to His bundle and coronary sinus was the longest in pacing at right atrial appendage , while the activation time in pacing at Koch triangle , Koch triangle with high right atrium and biatria was significantly shorter especially pacing at Koch triangle and Koch triangle with high right atrium1 There were no significant differences in right atrium pressure among all pacings1 Conclusion It is suggested that Koch triangle pacing could probably replace high right atrial with coronary sinus pacing and biatrial pacing 1

从心房激动顺序分析，右心耳起搏时，激动传至希氏束区及冠状窦区的时间最长，而 Koch三角、Koch三角+高位右房及双房起搏时则较短，尤其是 Koch三角、Koch三角+高位右房起搏缩短更明显。另外，不同部位、不同方式起搏时右心房压力无差异。结论 Koch三角起搏在某种程度上可替代高位右房+冠状窦起搏及双房起搏。

The concentration of sodium tungstate impacts on the activation energies notably. The activation energies increase the concentration of sodium tungstate is improved.

The results indicated that a dependable kinetic model could be obtained by modifying the Temkin equation by considering the H2 and NH3 adsorption factors. Activation energy for the ammonia synthesis reaction was obtained as 90.2 kJmol^(-1) after linear fitting the kinetic and thermodynamic parameters k, K(subscript H2) and K(subscript NH3) with the Arrhenius and Van't Hoff equation, which was much lower than that over iron-based catalyst, which indicated that the activation energy barrier of N2 dissociative adsorption on Ru was far lower than that on either the conventional magnetite-based catalyst or wustite-based catalyst; the hydrogen adsorption heat was 76.2 kJ mol^(-1), indicating that the adsorption of hydrogen on the Ba-Ru-K/AC catalyst was so strong that it inhibitied the dissociative adsorption of nitrogen.

结果表明，在Temkin方程中加入H2和NH3的吸附项能够获得可靠的动力学模型，用Arrhenius和Van't Hoff方程对动力学和热力学参数k、K(下标 H2)和K(下标 NH3)进行线性拟合，得到氨合成反应的活化能为90.2 kJmol^(-1)，远低于铁基催化剂，说明Ru上N2的解离吸附活化能垒远低于传统磁铁矿基催化剂和维氏体基催化剂。H2的吸附热为76.2 kJmol^(-1)，证明Ba-Ru-K/AC催化剂上H2的吸附较强烈，对N2的吸附有强烈的抑制作用。
