粒子注入 meaning in English
particle injection
Examples
- A single - ion microbeam facility is a set of system that can limit the diameter of the ion beam to the micron level and can deliver defined numbers of ions into an defined area of a cell
单粒子束装置( single - ionmicrobeamfacility )是一种可以将粒子束的束径限制在微米量级的范围内，并将预定个数的粒子注入到细胞中的某一指定位置的辐射装置。 - In the lhc the destabilizing effects of magnetic imperfections is more pronounced at injection energy , because the imperfections are larger and a because the beams occupy a larger fraction of the coil cross section
在lhc中，粒子注入能量中，不完美的电磁场产生的不稳定效应更为明显，因为缺陷的程度更大，粒子束占据环绕横截面的一个更大的部分。 - A single - ion microbeam facility is a set of radiation system that can limit the diameter of the ion beam to the micron level and can deliver predefined numbers of ions into a predefined area of a cell
单粒子束装置( single - ionmicrobeamfacility )是一种可以将粒子束的束径限制在微米量级的范围内，并将预定个数的粒子注入到细胞中的某一指定位置的辐射装置。 - In section one , we analyze the mechanism of lwi gain , and study the effects of the rabi frequency q of the driving field , the injection rates ratio rb / r ~ , the exit rate r0 , the decay rates ~ and rab between atomic levels , as well as 3 incoherent pump rate r on the gain without inversion , dispersion and population difference of the system . in section two , we discuss the effects of the detuning of the driving field and the probe field on the gain
在第一节中分析了无粒子数反转激光增益产生的机制、研究了驱动场的rabi频率、粒子注入速率比值r _ b / r _ c 、粒子退出速率r _ o 、能级间的自发衰减速率r _ ( c - b ) 、 r _ ( a - b )和非相干泵浦速率r对增益、色散和粒子数差的影响；第二节讨论了驱动场和探测场的失谐对无粒子数反转激光增益的影响。 - In chapter 3 , we studied the effect of gaussian transverse profile for the driving and laser fields on lasing without population inversion ( lwi ) in a closed v - type system and an open v - type system . moreover , we discussed also the effect of the unsaturated gain coefficient , the cavity - damping rate , the ratio of the atomic injection rates and atomic exit rate on the corresponding systems . in chapter 4 , we mainly discussed the effect of doppler broadening on the gain , dispersion and the frequency up - conversion of the open v - type lwi system and compared the differences and the same between the open system and the corresponding closed system
发现： ( 1 )在考虑doppler展宽的情况下，通过选取合适的实验室条件(比如合适的原子环境温度等)可得到合适doppler展宽值，从而使系统获得最佳增益； ( 2 )要想实现系统的频率上转换，同时又要获得足够强的无反转激光增益，则系统频率转换比不能选取的太大； ( 3 )对于开放系统，比较小的粒子注入速率比与退出速率对产生无反转激光是有利硕士学位论文摘要的： （ 4 ）由于dopp1oy展宽的存在，当探测场与驱动场的传播方向相反时，增益在探测场失谐的某一段区域产生振荡，且振荡的振幅、频率失谐范围的大小与dopper展宽的取值有关。
