Economic comparison among different electrovalence levels of Ningxia Shapotou Water Control Project Co., Ltd. 沙坡头公司不同电价水平的经济比较。
Huzhou industrial implementation of the Valley of gaofeng electrovalence and electrovalence, the price difference. 湖州对工业用电实行高峰电价和低谷电价，价格相差很多。
Based on the foregoing research, established the modal and empolder the calculation system of electrovalence. 在此基础上建立模型并开发了发电厂上网电价核算系统。
In winter, we use the electric boiler with thermal storage to help the gas power boiler and utilize the preferential electrovalence adequately. 冬季使用蓄热电锅炉来辅助燃气锅炉供暖，充分利用优惠低谷电；
Heat treatment on the preparation, structure, electrovalence of silver, releasing speed of Ag ions and antibacterial property of obtained blocks were investigated. 考察热处理制度对抗菌块体的制备及结构、银价态、银离子释放速度、抗菌性能的影响。
