My baby is also a good cold-flow nose for several days, there is no effect of medication, she was not justified, and a few days after their own good, and I think that is a process of sick children, so also there is a process, Unlike adults and high immunity to resume faster, in fact, medicine can only alleviate the symptoms can not be completely cured, the following will be a good time.
我家宝宝感冒好了也是流了好几天鼻涕,吃药也没有效果,后来就没有理她了,过几天后自己就好了,我觉得小孩子生病是一段过程,好也要有一段过程,不像大人免疫力高恢复得快,其实吃药只能缓解症状,并不能彻底治好,隔段时间自然会好的。

I think that English is to speak out but is not horizontal depending on judging one people's coming examination all the time.But, our system now do not identify mark right away.In current examination psychology right away looking like our Olympic Games slogan ,"I participate ,I enjoy ".
我始终认为英语是说出来的而不是靠考试来衡量一个人的水平,但是,没有办法,我们现在的制度就认分,本人的语法相当的烂,管他这法那法,成绩考试后见分晓,这次的考试心态就像我们的奥运口号一样&我参与,我快乐&。

C That popular fable of the sot who was picked up dead-drunk in the street, carried to the duke's house, washed and dressed and laid in the duke's bed, and, on his waking, treated with all obsequious ceremony like the duke, and assured atht he had been insane, owes its popularity to the fact that it symbolizes so well the state of man, who is in the world a sort of sot, but now and then wakes up, exercises his reason and finds himself a true prince.
流传着这样一则寓言:有一名醉倒街头的酒鬼被带到公爵的宫殿,下人为其洗漱更衣后安置到公爵的床上,当他醒来时,发现自己像公爵一般被一切谄媚的礼节款待,然后认定自己定是疯了。寓言之所以闻名遐迩,因为其恰如其分地影射了世人的生活状态:在世为人如同酒醉一般,但时或会清醒,恢复理性时他便成了真正的王孙公爵。

This problem is also important and valuable in Nonlinear Optics. It will be very helpful to understand how the aberrations affect the course of three- wave mixing, such as the change of conversion efficiency, the distribution of intensity and phase.Small signal solution of aberrated second harmonic generation is deduced from three-dimension three wave coupling functions. The numerical work gives out lot of results of different aberrations. The effects of the fundamental waves aberrations, which will change the conversion efficiency, distribution of intensity and phase in the frequency conversion, is analyzed. It shows that when walk-off and diffraction effects could be ignored approximately estimation of the phase distribution of second-harmonic wave could be done. The far field divergent angle and second moment radius of harmonic wave will vary with the aberration of fundamental wave, but the far field divergent angle will be obviously smaller than that of fundamental wave. The phase distribution of both fundamental and harmonic wave is measured using Hartmann-Shack wave front sensor in the experiment with 1064nm and 790nm lasers, respectively. Results are given.
