Abstract : the effect of correction of self - consistent potential on electronic structure in simple cubic nanocrystal particles is calculated by means of the green ' s function method in the tight - binding approximation , taking only the nearest neighbor matrix elements into account . the numerical results show that the electronic energy spectrum is shifted , the chemical potential is not equal to the atomic energy level , the electronic density at each lattice point is changed , and the variation of electronic density at surface lattice point is the largest 文摘:在紧束缚近似下，只计及最近邻的矩阵元，采用格林函数计算了自洽势修正对简立方纳米晶体颗粒的电子结构的影响，发现电子能谱发生了移动，化学势不等于格点原子能级，各格点的电子密度也发生了变化，其中以表面格点的电子密度变化最大。

Game players need to control the divers were swimming in the sea , the collection of gold coins and treasure . key corresponding to the four directions of movement , as long as the contact coin or entertainment can be added to , while others , such as fish , players drifted pet bottles carefully avoided , was not getting a good , the event will be reduced by one hit the lattice points of life , 3 : 00 total 游戏中玩家需要控制潜水员在海水中游动，收集金币和宝藏，方向键分别对应四个方向的移动，只要接触到金币或者宝箱就可以加分，而其他诸如鱼类漂流瓶等玩家需要小心避开，它们可不是好惹的，万一撞上则会扣去一格生命点数，总共3点生命值，好好把握啊。

A coding scheme is proposed to eliminate the redundancy of output vectors in pyramidal lattice vector quantization ( plvq ) . a fast algorithm of labeling lattice points and a fast algorithm of finding lattice points are presented . and the transmission priority in case of asynchronous transfer mode is suggested 提出了一种与图象本身无关的熵编码方法去消除金字塔格型矢量量化( plvq )的输出冗余：同时也提出了由格点输出索引和由索引输出格点的快速算法；而且还根据异步传输模式( atm )的特点，选择了传输的优先级。
