- Top of the list is steel baron lakshmi mittal who owns the world s second largest steel company lnm
位居排行榜首位的是钢铁大王lakshmi mittal ，他拥有世界上第二大的钢铁公司lnm 。 - Abstract : numerically solving equations governing the variations of the beam size and the curvature of wave front in the logarithmically nonlinear media ( lnm ) , the propagating characteristics of gaussian beams have been described in detail
文摘:根据对数型非线性介质中高斯光束的束宽和波阵面曲率变化所满足的耦合方程，采用数值计算对高斯光束的传输特性进行了详细的分析。 - When the sensing head equipped with rubber 4 # with diameter of 8mm and length of 12mm is pressed and its incipient wavelength shifts 0 . 5 - lnm , its alarming level can be set as 1nm , and its response tune for petrol is 5 minutes
用直径为8mm 、长为12mm的4 # (上述配方)橡胶棒装备该传感头，传感头的初始波长预漂0 . 5nm ? 1nm时，传感器的漏油报警限可设定1nm ，对汽油的溶胀响应时间为5分钟。 - To illustrate the superiority of this type of transition , the author adapted the local normal mode ( lnm ) based on couple - mode theory to explain the coupling between two lowest order modes along the transition . for the two important parameters , propagation constants difference between the two modes apy and mode coupling coefficient cy , which denoting power coupling between lnms , the approximation expressions using structure parameters were worked out . then the author compared three typical different transitions according to the demanding of power coupling , at last concluded that the parabolic - type transition can transport the light in shortest length with lowest loss
对于表征局部标准模之间功率耦合的两个重要的参数_ ( ij ) (模式传播常数差)和c _ ( ij ) (模式耦合系数) ，推导了用器件结构参数表达的近似公式，然后根据功率耦合的需求，在常见的三种不同轮廓的过渡区之间进行了比较，得出了抛物形轮廓过渡区能够使光束在最短尺寸内以最低损耗通过波导的结论。
