需要时

In contrast to healthy indiiduals, neuromuscular patients showed piecemeal deglutition with seeral swallows oer seeral breathing cycles for each bolus.

与健康人相比，患有神经肌肉疾病患者吞咽1个水丸时需要几个呼吸周期进行多次一点一点的吞咽。

CMA, as an alternate deicer, tends to inhibit corrosion and appears to be relatively harmless to the environment. But CMA is expensive because of the high price of its material, and it has less ability in melting ice than sodium chloride. Besides these, CMA sticks to wet surfaces and can congeal to form hard chunks, difficult to store for a long time, dusty and a strong vinegar smell when spread.

而CMA是对氯化物盐除冰剂的重大改进，CMA具有无污染，环保的特点，对金属几乎无腐蚀，但由于原料价格昂贵，使得CMA的价格不菲，CMA对冰的融化能力不如氯化钠，CMA易结块，不宜长期储藏，在撒布时形成的粉尘及刺鼻的酸味亦是需要改进的地方。

When you get the "I don't want to work" feeling, you need to delve deeper into your emotions.

It is sometimes so treated prior to processing into edible product by bleaching and deodorization.

用它加工食品时，有时需要预先进行漂白和脱味处理。

"I would have to consider it as an option," Thomas said of whether he would consider depigmentation if the discolored spots spread.

"我需要考虑这个选择"，thomas在谈到移除皮肤色素时说到那时候，我会做出决定，现在，还不必要。

The main research contents and results are given as follows:(1) Principles and characteristics of different types of polarization controllers are analyzed, the compare of the difference of these polarization controllers are discussed based on them, drawn a conclusion that the polarization controller which based on squeezing fiber and has variable delay quantity are suitable for high speed optical communication system.(2) The reset principle of the typical four channel polarization controller which is based on squeezing fiber is analyzed, and the design of its concrete reset scheme is given based on them. The reset process and the corresponding operation list are given in detail.(3) The systematical experiment is made when the typical four channel polarization controller is put into the PMD compensator. The experiment result showed that the channel which needs reset can efficiently return to the mean place, and the effect of reset was good, it didn't cause any badness infection on PMD compensation.(4) A new type optical signal time-domain depolarizer is given, and a new PMD compensate method is given based on it.

由此得出延迟量可变型光纤挤压型偏振控制器适用于高速光通信系统的结论；(2)具体分析了典型的四通道光纤挤压型偏振控制器的复位原理，并在此基础上对其进行了具体复位方案的设计，给出了各种情况下的详细复位流程和相应的复位操作列表；(3)将四通道光纤挤压型偏振控制器应用于偏振模色散补偿器中进行系统实验，实验结果表明，需要复位的通道能有效地回到中间值，复位效果良好，且复位未对PMD补偿产生不良影响；(4)设计了一种新型的光信号时域退偏器，并基于该退偏器提出了一种新型的偏振模色散补偿方法。

When inflation, the depreciation reserve funds are often unable to meet the needs of asset replacement.

当发生通货膨胀时，折旧储备的资金往往不能满足重置资产的需要。

The cycling life of Ni 〓 was measured with powder microelectrode by cyclic voltammetry for the first time. Results show that the depth of charge is up to 75%, and the depth of discharge almost reached to 100% when the scanning range is controlled within 0～ 0.6V vs.

对Ni〓粉末微电极的测试表明，当控制三角波扫描范围0～0.6V、扫描速度20mV/s时，每次循环电极的充电率可达到75%，而放电率接近100%，完成一个周期仅需要1分钟，因此极大地缩短了测试时间。

Thx for being dere when i need sum1 to be rely on...

谢谢你在我需要依靠的肩膀时出现。。。

In the negative and interrogative forms, of course, this is identical to the non-emphatic forms.

。但是，在否定句或疑问句里，这种带有"do"的方法表达的效果却没有什么强调的意思。
