您要查找的是不是：
- Thus, optical-wavelength light can excite an electron at an impurity atom from one discrete state to another without knocking it all the way to the conduction band. 因此，一般的光波可以将杂质原子里的电子从一个离散的能态激发到另一个，而不会把它打到更高的导带。
- Planar defects can be twins/bicrystals,stacking faults and/or interstitial stacking layer introduced by impurity atoms. 面缺陷可以是孪晶或双晶,层错和由杂质原子聚集在特定原子面所形成的间隙原子层。
- The influences of rolling process and impurity atoms on the texture developments were also analysed. 同时也分析了钢板变形过程及杂质原子对织构形成的影响。
- When the electrical characteristics are dictated by impurity atoms, the semiconductor is said to be extrinsic semiconductors. 如果半导体的电学性质归因于其中的杂质原子，那么它将被称为杂质半导体。
- The coupled twins induced by impurity atom in FCC crystal 杂质原子在面心立方晶体中诱发的成对挛晶
- Hardening and strengthening of metals that result from alloying in which a solid solution is formed.The presence of impurity atoms restricts dislocation mobility. 由于形成固溶体的合金化过程引起的金属硬化和强化,其机制是异类原子的存在限制了位错的可动性。
- Calculations have been made for the configurations of single-walled carbon nanotubes containing substitutional nitrogen impurity atoms with ab initio density functional theory. 摘要利用第一原理，通过密度泛函理论计算掺杂氮原子的单壁碳纳米管几种可能的几何结构。
- Foreign nationals were asked to leave the country. 外国侨民被要求离开该国。
- Slight displacements of atoms relative to their normal lattice positions, normally imposed by crystalline defects such as dislocations, and interstitial and impurity atoms. 原子相对于它们正常点阵位置的轻微位移,通常是由晶体的缺陷,如位错、间隙原子、杂质原子存在引起的。
- In electroplated metals, these defects are primarily dislocations, twins, and deposited foreign atoms or molecular groups. 对于电镀的金属来说，这些缺陷主要是位错，孪晶和其沉积的异类，原子或分子基因。
- The local vibration mode induced by a impurity atom in a diatomic linear chain 一维双原子链中杂质引起的局域振动模
- The local vibration mode induced by a impurity atom in a monatomic linear chain 一维单原子链中杂质引起的局域振动模
- Daily practice is the trick in learning a foreign language. 每天练习是学会一门外语的诀窍。
- A rapid quenc hing of PL is observed above 0.2 at% of Ag concentration due to lattice defects and impurity atoms,however,the optimal concentration of Ag + in the EL efficiency is about 1 at%. 当 Ag+的浓度达到 0 .;2at%25;薄膜的光致发光发生很强的淬灭;但是电致发光的淬灭浓度却达 1at%25。
- She has a foreign accent that I can't quite place. 她有外国口音，但我听不出是哪儿的口音。
- The country was bled white by her foreign rulers. 这个国家在异族的统治下民穷财尽。
- May be a little austere for foreign taste. 可能对外国口味而言过于朴素了些。
