The conclusions show that with γP0 increasing the nonlinear dispersion curves shift to the negative region of δ,the upper branch of the curve will form a ring when γP0 exceeds a critical value,while the anomalous dispersion region of group velocity dispersion induced by fiber Bragg grating vanishes,group velocity dispersion becomes only one normal dispersion region.

And such a luxury to him was this petting of his sorrows, that he could not bear to have any worldly cheeriness or any grating delight intrude upon it; it was too sacred for such contact; and so, presently, when his cousin Mary danced in, all alive with the joy of seeing home again after an age-long visit of one week to the country, he got up and moved in clouds and darkness out at one door as she brought song and sunshine in at the other.

进来的时候，他马上就避开了她。她到乡下去作客，只住了一星期，仿佛时隔三秋似的，她现在又看到自己的家，真是高兴极了。但是，当她唱着歌欢快地从一扇门走进来的时候，汤姆却站起身来乘着阴云暗影从另一扇门溜出去了。他避开平常孩子们经常玩耍出没的地方，专找适合他此时心情的僻静地方。河里的一条
