negative valence

No negative valence gold in Au - bearing sulfide

含金硫化物矿物中不可能存在负价金

An element introduced into a semiconductor with a negative valence greater than that of the pure semiconductor .

施主放进半导体中的元素，其负价大于纯半导体。

COMMENT ONNO NEGATIVE VALENCE GOLD IN Au-BEARING SULFIDE & A Discussion with Wang Yuming et al

评含金硫化物矿物中不可能存在负价金&与王玉明等同志商讨

By analyzing a variety of route optimization algorithm based on the traffic matrix , we decide to use the negative valence ring algorithm to calculate the set of route optimization , through optimize high traffic load links , we can make the balance of traffic on each link .

通过分析基于流量矩阵的各种路由优化算法，采用负价环算法将估算的流量结果用作计算路由优化集的输入，优化高负载链路的流量，优化结果能有效的均衡各链路上的流量。

The difference charge density map shows that Al atoms loose significant amount of electrons when their nearest neighbour atom is Mn , and the Mn atom gains electrons . This means that the transfer of electrons from Al to Mn occurs , and Mn has a negative valence .

所得差值电荷密度表明，当Al原子的最近邻原子为Mn时，Al原子失去较多的电子，Mn原子得到电子，说明发生了Al的外层电子向Mn原子转移，Mn显示负的化合价。
