过高

Low pH caused the amidogen of microorganism in the activated sludge protonized and high pH caused make the hydroxyl salinized, and increased the hydrolyzation of microorganism which would have side effect on the denatured effect.

过低的pH值会导致活性污泥中微生物氨基质子化；过高pH值会使之羟基盐化，而且过高或者过低的pH值还会增强微生物的水解作用，这样影响活性污泥的改性效果。

When the sodium lauryl sulfate and p-octyl polyethylene glycol phenyl ether is used and its level in 3% and 6: 4 ratio, the polymerization process has the lowest coagulum and the highest monomer conversion. Higher reaction temperature and more level hydroxyl value lead to more coagulum, the latter also lead to larger particle size. The acid value has larger influence on viscosity and coagulum, there exist a best range. The emulsion particle size is larger for its hydrophilicity, most of its particles are connected together.

在含较高亲水单体的乳液聚合体系中，难以制得稳定的预乳化液，不能采用工业生产中常用的预乳化工艺，而只能采用混合单体直接滴加的方法；由于单体混合物的亲水亲油值较高，用阴离子型乳化剂十二烷基硫酸钠和非离子型乳化剂聚乙二醇辛基苯基醚混合，用量为单体总量的3％，且比例在6：4时，乳液聚合时具有最低的凝聚物含量和最高的单体转化率；乳液聚合反应温度升高，可以提高单体转化率，增加反应速度，但凝聚率相应提高；随着羟基单体含量的增加，聚合过程中凝聚率增加，聚合物乳胶粒平均直径增加；羧基单体有一个最佳的用量（2.6％），过高或过低凝聚率均提高；羧基含量对乳液的粘度有较大的影响，当羧基含量较低时，羧基含量增加，乳液粘度增加明显；含羟基乳液粒子由于含亲水基团较多，使得乳胶粒径增大，乳胶粒子大多数互相凝聚在一起，处于凝聚态。

妊高症的发病原因，至今还未阐明，根据流行病因学调查发现，妊高症的发病原因可能于以下因素有关：(1)精神过分紧张或受刺激致使中枢神经系统功能紊乱；(2)寒冷季节或气温变化过大特别是气压高时；(3)年轻孕妇或高龄初产妇；(4)有慢性高血压、肾炎、糖尿病等病史的孕妇；(5)营养不良；(6)体型矮胖；(7)子宫张力过高，如羊水过多、双胎、糖尿病巨大胎儿及葡萄胎等；(8)家族中有高血压史，尤其是孕妇之母有妊高症史者。

In the proposed device to remedy the defect that overhigh withstand voltage of thyristors used in converter are needed due to the overhigh DC link voltage, a method to control DC link voltage is put forward, that is, a special control logic for full-controllable switching elements is designed to make them equivalent to half-controllable switching elements which are naturally turned on and turned off by triggering, then connecting such a half-controllable switching element in series with DC link the defect of overhigh DC link voltage is effectively solved.

为了克服该装置直流母线电压过高，因而对逆变器开关管耐压要求过高的缺点，提出一种对直流母线电压进行控制的方法。对全控型开关器件设计一种特殊的控制逻辑，使其等效为一个自然导通、触发关断的半控型开关器件，将该半控型开关串联在直流母线上，有效解决了直流母线电压过高的问题。

To compensate the descent of pH for the heat-up, exalting the Tris-HCl buffer's pH can avoid the abscission of the purine and make the long sequence PCR go on smoothly. The GC-rich template's secondary structure is complex and stable. The organic reagent methylamine contributes to uncoil the secondary structure.The pfu DNA polymerase has more fidelity and thermostability than Taq DNA polymerase.

高GC含量使模板二级结构复杂而稳定，一般热启动难于解开，而变性温度过高、时间过长又不利于DNA聚合酶的活性作用发挥，于是借助能缓释模板二级结构的有机试剂甲胺扩增高GC含量模板。pfu DNA聚合酶比Taq酶有更高的保真复制性能和热稳定性，更有利于高GC含量模板的扩增。

First,the content of surfactant should be more than 18 percent and the content of anion surfactant should be kept in proper proportion to the content of nonionic surfactant. Second,the content of zinc naphthenate should be kept in directly proportional to the content of other surfactant. Third,the content of rosin shouldnt too higher and the content of oleic acid should be kept in directly proportional to the content of rosin. Fourth,the content of water should be kept in a low level (less than 8%);otherwise emulsifier oil will delaminate. In addition,the requisite content of sodium heavy alkyl benzene sulfonate is higher than petroleum sulfonate.

试验表明在以松香、重烷磺酸钠、石油磺酸钠为主要乳化剂时，要获得优良的乳化液，需满足以下几个条件：(1)需在乳化油配方中加入适量的乳化剂，且其中阴离子乳化剂总量与非离子乳化剂总量的应保持适当的比例；(2)乳化油中环烷酸锌的量与其它乳化剂总量要保持正比关系；(3)乳化油中松香的量不易过大，且油酸的加入量应与松香量成正比；(4)乳化油中水分含量不易过高(一般不能大于8％)，过高时稳定性不好，易分层。
