Unlike previous models in which overexpression of the amyloid precursor protein results in amyloid plaque formation, have produced mice that overexpress only Aβ40 or Aβ42 and prove that Aβ42 is critical for the formation of amyloid deposits in vivo.

不同于早先调控淀粉样蛋白前体蛋白的动物模型，McGowan 等(Neuron， Vol 47， 191-199， 21 July 2005)培养了专一表达Aβ40或者 Aβ42的老鼠，结果直接证明了Aβ42 确实是引起淀粉样蛋白沉淀的主要因素，而不是Aβ40。

What Jesus gathered into His life from His prayers we can never know; but this we do know, that the prayerless life is a powerless life.

主耶稣藉着祷告而充实了属灵的生命，我们不太明了，但是我们确实知道不祷告的生命，是没有力量的生命。

But in practical operating, overvoltage caused by reignition of the vacuum switching device frequently appears, and it result in damage of the capacitor bank or the switchgear itself. Ensuring the switchgear against reignition and installing a protective device are two main approaches to avoid the phenomenon. In this paper, a study on overvoltage caused by reignition due to capacitor bank switching with the vacuum switching device and its preventive measures are carried out. The main work which has been done and researches are as follows: 1. The producing mechanism of overvoltage and its influence factor are analyzed. It is pointed out that single-phase reignition is the main reason for damage of the switchgear and two-phase reignition is the main reason for damage of the capacitor bank,so overvoltage of single-phase reignition and two-phase reignition are the emphases of prevention. 2. Analysis of the special working condition of the operating switch for capacitor bank is carried out. It indicates that the vacuum switching device is difficult to realize no-reignition under this operation condition, so it is more practical to adopt protection devices. 3. Analyses of protection effect of RC and MOA and their shortages are carried out. It shows that the two methods can only restrain effectively overvoltage caused by single-phase reignition, and they cannot protect the capacitor bank when reignition of two-phase occurs. 4. The operation principle of G-R damping device is analyzed and discussed emphatically.

本文针对真空开关投切电容器组时因重燃而产生的过电压及其防治措施进行了研究，所开展的主要工作和研究结果如下： 1、对过电压的产生机理及其影响因素进行了分析，指出单相重燃是导致开关设备损坏的主要原因，而两相重燃则是导致电容器组损坏的主要原因，因此单相重燃和两相重燃过电压是防护的重点； 2、对电容器组操作开关的特殊运行条件进行了分析，指出在这种运行条件真空开关难于实现不重燃，因此采用保护装置更具有现实意义； 3、对RC与MOA的保护效果和存在的不足进行了分析，指出这两种方法均只能有效抑制单相重燃过电压，而不能在发生两相重燃时保护电容器组； 4、重点对G-R阻尼装置的工作原理进行了分析和讨论，指出该装置接入后线路中将会出现两种频率的高频振荡，而电容器组上的过电压是由这两种振荡共同决定的； 5、根据对上述两种振荡的分析指出存在一个最佳电阻值使得过电压最低，并提出了电容器组电压和最佳电阻值的近似求解方法； 6、使用电气暂态分析软件MATLAB对G-R装置的保护效果进行了仿真计算，证实该装置确实可以有效抑制重燃时的电容器组过电压； 7、根据仿真与近似计算结果的偏差提出了近似计算的修正方法，经过修正后的过电压计算结果与仿真结果吻合较好； 8、对G-R装置中放电装置G与阻尼电阻R的要求进行了分析，指出采用编织电阻和真空间隙可能是最佳选择。

Indeed one of Cascarellian's spies,who had been a guard at the pal ace the night of the slaughter,had seen the creature everyone called The Scyt he-Meister washing his weapons in one of the Palace's many fountains.The info rmant had escaped the massacre without harm coming to him,and reported that u nlikely as it seemed the semi-mythical figure of The Scythe-Meister bore a sub tle but undeniable resemblance to Zarles Kreiger.

而他的一个在皇宫做守卫的探子报告说他曾经在王室大屠杀当夜亲眼见过那个被叫做镰刀手-梅司特的怪物，当时它正在皇宫的喷泉上濯洗它的武器，那个探子说虽然自己也不确定是不是看错了，那个半人半鬼的镰刀手-梅司特虽然机敏过人，但看上去长得确实有点象杀手扎尔兹·克里奇。

However, my recent interviews with children living in the group of islands that includes Tertia show that these children spend much more time talking about their biological parents than about other adults in the village.

即使是Tertia的children确实和他们的父母谈话多也不能说明他们就不是由an entire village带大的，很可能其他的adults在这些小孩的成长过程中也起了很大的作用。

Finally, WangZuXian became the boiling point before news of rumours now exact news confirmed, WangZuXian had ordained, when they heard the news of the WangZuXian like friends in the ear, many people are not acceptable, they feel like WangZuXian such a woman will not choose to live so wonderful, she's future is bright, why would choose tonsured? Because of economic reasons or family reasons.

王祖贤终于还是出家了，之前在沸点上传言的消息现在已经被确切的新闻所证实了，王祖贤确实已经出家了，当这个消息传到喜欢王祖贤的朋友们的耳朵中的时候，很多人是不能接受的，他们觉得像王祖贤这样一个女子怎么也不会选择出家，生活如此精彩，她的前途应该是一片光明的，为什么会选择出家呢，是因为经济原因还是家庭原因。
