再发生的

This is a degeneracy in the principles of liberty...

这是从自由原则的倒退，就是再过四个世纪也不应该发生。

It is vital to reduce the variation of Dracaena fragrans cv.massangeana and Dracaena fragrans cv.lindenii by preventing the differentiation from forming callus as well as the reduction or the prevention of callus redifferentiation.

避免脱分化形成愈伤组织以及减少或阻止愈伤组织再分化是减少金心也门铁和金边也门铁这类嵌合体品种发生变异的关键之一。

Therefore, we utilize optical switch to switch over two routes P1 and P2 which are normal feeder fiber P1 and protecting fiber P2. Signal pass P1 and P2 and through 2X2 coupler, splitter, and 2X1 coupler into the drop fiber. Finally pass through WDM coupler and filter into ONU.

传输时利用光开关切换成两路路径P1和P2，分别为在正常下的P1馈线光纤和发生错误时切换成P2保护光纤，再经2X2耦合器、分歧器和2X1耦合器，进入终端光纤，最后经分波多工耦合器和滤波器后进入光网路单元。

3.3需方向供方提供汽轮机回热系统热平衡图一套，具体见技术规范书附件，如上述工况发生供方认可的变化，需方再另行提供一套汽机回热系统热平衡图。

After esterification, the ethyl-2-chloro-3-phenylpropionate reacts with diethyl malonate under the catalysis of sodium ethylate, and we obtain the corresponding triethyl ester. The-benzylsuccinic acid is formed by the triethyl ester reacting with concentrate hydrochloric acid and taking place hydrolyzation and decarboxylation reaction at the same time. In order to avoid the formation of cinnamic acid, the sodium ethylate and diethyl malonate must be react sufficiently. The course has simple operation, inexpensive materials and better yield.

具体制备工艺为：首先以L-苯丙氨酸为原料采用重氮化方法得到-2-氯-3-苯基丙酸，再经酯化得到-2-氯-3-苯基丙酸乙酯后在乙醇钠催化作用下和丙二酸二乙酯缩合，发生SN2反应，得到相应的三乙酯，然后经水解和脱羧，得到-苄基丁二酸；在实验中乙醇钠要和丙二酸二乙酯充分反应，避免生成肉桂酸乙酯；该过程操作简单，原料便宜，产率较高，总收率可达到26.8%。

Manufacturing process, quality control method, important raw material and excipient, or equipment, etc.

当影响产品质量的主要因素，如工艺、质量控制方法、主要原辅料、主要生产设备等发生改变时，以及生产一定周期后，应进行再验证。

"It was a freakish incident. If I tried it 100a million times it couldn't happen again. If I could I would have carried on playing!"

"这是一次诡异的事件，如果我再尝试100万次这也不能再次发生，如果我可以的话，我就会去参加比赛！"

That seems unlikely to happen:"I am no longer having fun playing football and if I would only play halfheartedly it would be no good to anyone",added Deisler,who was considered to be one of the most talented players ever to play in Germany.

但这似乎不太可能发生："我已经无法再从踢球中享受乐趣了，如果我只能半心半意地踢球这对任何人都没好处。"戴斯勒补充道，他曾被认为是德国历史上最天才的球员之一。

Based on the dynamic materials model theories,hyperbolic sine equation and two Liapunov stability criteria,the processing maps of T122 heat resistant steel were constructed using the data obtained from isothermal hot compress test s by means of a Gleeble 3 500 simulator.

结果表明：T122钢在1085℃以上、应变速率小于0.37s-1压缩变形时，功率耗散效率达到峰值0.2，此时发生了完全动态再结晶；对于工业热加工，建议在变形温度为1085~1150℃和应变速率大于0.13s-1的范围内选择加工参数

Sometime when something happen in the house, those outstation ppl will feel difficulties, regret can't be beside to accompany, can't help anything plus can't take leave so urgent, really feel upsad.

当家中有事情发生时，我们这些游子难免会有很多情绪出来，感憾不能在身边陪伴，其余却帮不上忙，再加上工作上的不方便，真是左右为难。
