But time will not allow me come back to the past time. It let me miss my direction on the coordinate axis of life. The original love ask me go ahead in the direction of straight .In that case.I will not meet the 0degree ice .And straight forward this road .I can see the raising sun.And will find out the beautiful view which others will never meet .If I turn my direction into the opposite one .I will just see the mirage, I trusted her. From childish time to grow up. I accepted many regards from different region and different persons.I shows a big smile all the time . I learnt thanks. Thanks for god let me live in such beautiful world. Thanks for the person who care of me; I leant sympathy .

但是时间不允许我再回到原点，它让我在人生的坐标上失去的方向，原本的爱一直指导我向正坐标走，它告诉我那样我不会遇到零度坚冰，一直走下去会看到初升的太阳，会看到很多别人的看不到的美景，它告诉我如果真得往恨的方向走，我看到的只是海市蜃楼，所以我听它的，从小到大，我接收到了来自同或者不同的地域的人的爱护，我一直咧开一张嘴笑着，我开始学会了感谢，感谢上仓让我生在这样一个世界，感谢我身边每一个人对我的关怀；我开始学会同情，同情一些孤儿老人和备受战争残害的人…。。

Coordinates of the top-left corner (or bottom-left in case of images with bottom-left origin) of the destination image rectangle where the source image is copied.

The system we selected is the positive donor ion located in the centers of GaAslGaAsAl quantum well (doped density of Al is 0.33) in the process of calculation. We take the center of well as the origin of coordinates. We noticed that the electron"s effective mass is different in the well and in the barrier, but didn"t pay attention to the mismatch of the dielectric constant.

在计算过程中，我们选取的体系是0中心的正施主离子处于 GaAS／GaAsAI（其中以的搀杂浓度为 0.3 3）量于阶中心，把量子阶中心选作坐标原点，考虑了在阶中和垒中电子的有效质量的不同，但没有考虑在阶中和垒中介电常数的失配性。
