The lifetime of free carriers in a silicon-on-insulator (SOI) rib waveguide, which is used for Raman amplification, is studied in connection with the nonlinear optical loss.
研究了用于喇曼放大的绝缘硅(SOI)脊形波导中自由载流子寿命与非线性光学损耗的关系。
The results show that the magnetic field can effectively change the relative ratio between the singlet and the triplet polaron pairs, resulting in an increase in the density of the free carriers.
从聚合物光电池中光电流和暗电流的产生机制出发，对该现象进行了解释，认为外加磁场可以有效改变单重态极化子对和三重态极化子对之间的相对比例，进而使自由载流子浓度增加。
The design incorporates a channel thin enough to become entirely devoid of carriers (ie, free electrons or holes) when switched off, thus acting as a valve, yet full of them when switched on.
这一设计包含了一条足够细的隧道，当它关闭时，里面完全没有载流子(电子或空穴)，当它打开时，里面便充满了载流子，起到了阀门的作用。
Meanwhile, two thirds of travellers (64 percent) do not know what their free-baggage allowance is across the major carriers, whilst 77 percent are unaware of what the differing card-payment fees are.
同时，三分之二（64%）的旅客不知道他们的免费行李额。 另外，77%的旅客不知道不同的信用卡支付的额外费用。
A smart phone running Skype or something similar would be essentially free of usage charges and unfettered by all the restrictions that carriers impose.
使用运行SKYPE或类似软件的智能手机不单可以免费打电话，还不用受运营商的条条款款限制。
If tied to a two-year data contract, a seven-inch Android tablet could even be given away by mobile carriers for free.
如果绑上两年的数据合同，一部7英寸安卓平板电脑甚至能免费送给手机使用者。
Analogous to a snow avalanche on a steep mountain slope, an incoming light pulse initially frees just a few charge carriers which in turn free others until the original signal is amplified many times.
像陡峭山坡上的雪崩一样，一束入射光的脉冲最初仅仅释放少数的电荷载子(charge carrier)，这些电荷载子再轮流释放其他的载子，直到原始信号被放大很多次。
Fixed-line carriers like AT&T and Verizon, as well as cable companies such as Comcast and Time Warner, are now free to throttle download speeds in the name of "network management".
固定电话运营商如美国电报电话公司和弗莱森通讯（Verizon），还有你像康卡斯特和时代华纳（Time Warner）之类的有线电视公司，他们现在都可以以“网络管理”为名义来任意限制下载速度。
However, through computer simulation, it can obtain not only the decay curve of free photoelectrons, but also the behavior curve of carriers in all kinds of trapping centers.
而这种计算机模拟方法不仅可以得到自由光电子的衰减曲线，还可同时获得各种俘获中心中载流子的行为曲线。
This review deals with the diffusion properties of a species in the cell-free and cell-occupied carriers.
本文综述了对于组分在固定化细胞及其载体中的扩散性质的研究现状。
This is designed to "reduce" cup noodles volume, cutting packaging and transportation costs down, to free up more space for carriers.
我们发现杯面内部有空余空间，可以采用折叠压缩的方式减小杯面的体积。
