In the matter of redaction, it allows that "for liturgical or musical or other unknown reasons, psalms may have been split up or joined together" in course of time; and that "there are other psalms, like the Miserere mei, Deus , which, in order that they might be better fitted to the historical circumstances and the solemnities of the Jewish people, were slightly re-edited and changed by the omission or addition of a verse or two, so long as the inspiration of the entire text remains intact".

在这件事的节录，它可以让"为礼仪或音乐或其他不明原因，诗篇可能已经分裂或一起"在过程中的时间，以及"有其他的诗篇一样， miserere梅， deus ，其中，为了使他们可能会更好装到历史情况和solemnities的犹太人民，略有重新编辑和改变所遗漏或增设一个诗或二，只要灵感整个案文保持不变"。

Ultimately, vulnerable groups of neurons atrophy and die in a process that may involve excitotoxicity (overstimulation of neurotransmitter receptors on neuronal surface membranes), collapse of calcium homeostasis, inflammation, and depletion of energy and growth factors. A form of apolipoprotein E, apoE4, contributes to the abnormal accumulation of A and tau, but probably also damages mitochondria and the cellular cytoskeleton. A , tau, apoE and -synuclein interact with many other molecules and modulate diverse signalling cascades that regulate neuronal activity and survival.

最后，易感神经元会萎缩直至死亡，原因可能有兴奋性中毒（神经递质对神经元表面受体的过度刺激引起），钙稳态失衡，炎症反应，能量和生长因子的耗尽。apoE4的产生可导致A肽和tau蛋白的异常聚合，可能也损害线粒体和细胞骨架。A肽、tau蛋白、apoE和突触核蛋白可与很多分子反应，也可调节不同信号级联反应，这些级联反应对于维持神经元活动性和生存性意义重大。

However, too often some of the reasons may be related to the following: the one, local stimulus, such as perineal cleaning baby care too much, genital eczema, pinworm, wet diapers or pants too tight and so on stimulation. 2, psychological factors, if the children were the family atmosphere of tension, lack of motherly love, suffer discrimination and so emotionally can not be met through its own stimulus to seek vent, resulting in leg movements folder. 3, larger children may be related to puberty by sex-related stimuli.

但过于频繁可能与以下一些原因有关：1、局部刺激，如对孩子会阴部清洁护理过多、外阴湿疹、蛲虫、尿布潮湿或裤子太紧等等的刺激。2、心理因素，如有的儿童因家庭气氛紧张、缺乏母爱、遭受歧视等，在感情上得不到满足，通过自身刺激来寻求宣泄，从而产生夹腿动作。3、大一点的的孩子可能与进入青春期、受到与性有关的刺激有关。

Simultaneously, the total extractible myoglobin decreased and the proportion of metmyoglobin increased significantly when the pressure above 400MPa. Beef discoloration after pressure processing may result from oxidation of ferrous myoglobin to ferric metmyoglobin, globin denaturation and structural changes. At 40℃, the changes of beef color was similar to that of room temperature's. When the temperature rise to 60℃, most of muscle proteins denatured, a small quantity of native myoglobin could not affect the color of beef significantly. Therefore, protein denaturation was attributed to the main cause of discoloration in beef muscle after pressurization at 60℃.

压力处理导致色泽变化的直接原因可能是由于二价铁的肌红蛋白氧化成三价铁的高铁肌红蛋白、球蛋白的变性及结构的变化所致。40℃时的压力处理，色泽的变化规律与室温下相似，只是色泽变化的程度更为剧烈，蛋白质变性在色泽变化中起到的作用逐渐加强。60℃下的压力处理，绝大部分蛋白质发生变性，少量未变性的肌红蛋白对色泽不会产生明显的影响，此温度的压力处理，蛋白质变性是造成肌肉失去红色的主要原因。

The transforming growth factor-β superfamily, a large group of highly conserved growth factors including TGF-βs, activins and BMPs, regulate a wide variety of cellular functions such as proliferation, differentiation, apoptosis and migration. Signals from these growth factors are transduced by a group of Smad proteins. To date, there are nine vertebrate Smads, including the receptor-activated Smads , Smadsl-3, 5 and 8, the common mediator Smad4 and Smad4β, and the inhibitory Smads, Smad6 and 7. Signaling is initiated when the ligand induces assembly of a heteromeric complex of type Ⅱ and type Ⅰ TGFβ receptors. Then R-Smads are directly phosphorylated by activated type I TGF-β receptors.

在多种SMADS中，SMAD5令我们产生兴趣，基于三个原因：1、Smad5基因敲除胚胎中发现卵黄囊的异位造血以及CFU-GM祖细胞数目增加，表明SMAD5可能是早期造血发育的负向调控基因。；2、应用反义核酸封闭Smad5可以逆转TGF-β对祖细胞增殖的抑制效应，表明它可能介导TGF-β信号转导，后者的异常，包括某些SMADS的功能异常，和白血病紧密相关；3、Smad5基因定位在人染色体5q21，此区域的缺失和急性髓系白血病和骨髓增生异常综合症相关，因此，Smad5被怀疑为白血病抑制基因。

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。
