1. We analyze the generation of external cavity frequency - doubling with knbo3 crystal theoretically . in order to get the second - order nonlinear conversion from 858nm to 429nm with knbo3 , we use non - critical type - i phase - matching to avoid the walk - off effect the corresponding optimum focusing condition is as followings : double refraction parameter b = 0 , focus parameter = 2 . 84 , optimum phase mismatch parameter = 0 . 574 . based on the theoretical analysis and numerical calculations , we obtain the ideal nonlinear conversion coefficient about 1 . 45 % / w with crystal length of 7mm and 2 . 07 % / w with crystal length of 10mm at the phase - matching temperature around 23 . 50c
   根据对其倍频原理及性能的分析讨论，在用该晶体完成波长从858nm到429nm的二阶非线性转换时，采用非临界相位匹配条件(此时无离散效应，对应的双折射参数b = 0 ，共焦长度为= 2 . 84 ，最佳相位失配因子为= 0 . 574 ) ，在相位匹配温度约为23 . 5时，理论上通过计算得到理想情况下非线性转换系数约为1 . 45 / w (长度为7mm ) ， 2 . 07 / w (长度为10mm ) 。
2. Not a hint , however , did she drop about sending me to school : still i felt an instinctive certainty that she would not long endure me under the same roof w with my doll on my knee till the fire got low , glancing round occasionally to make sure that nothing worse than myself haunted the shadowy room ; and when the embers sank to a dull red , i undressed hastily , tugging at knots and strings as i best might , and sought shelter from cold and darkness in my crib
   自我生病以来，她已把我同她的孩子截然分开，指定我独自睡一个小房间，罚我单独用餐，整天呆在保育室里，而我的表兄妹们却经常在客厅玩耍。她没有丝毫暗示要送我上学，但我有一种很有把握的直觉，她不会长期容忍我与她同在一个屋檐下生活。因为她把目光投向我时，眼神里越来越表露出一种无法摆脱根深蒂固的厌恶。
