水中的溶解性固体,其组分主要为溶解性的盐类。当水中含有大量的溶解性固体时,可能使水污染带有苦咸味。因此它是水质评价的一项重要指标。但测定时需经过滤,并且烘干至恒重,操作比较麻烦。电导率是用数字来表示水溶液传导电流的能力,用于监测水中溶解性矿物质浓度的变化,是估算水体被无机盐污染的指标之一。其大小与水体中的阴阳离子的浓度呈正比,与水中的溶解性固体有密切关系。为了了解电导率与溶解性固体的相关程度,我们从1986年起,对西江高要河段水体的电导率及溶解性固体的含量进行了动态监测, Soluble solid in water, its components are mainly soluble salts. When the water contains a lot of dissolved solids, it may cause water pollution with bitter and salty taste. Therefore, it is an important indicator of water quality evaluation. However, the determination of the need to be filtered, and dried to constant weight, the operation is too much trouble. Conductivity is the ability to numerically represent the conductivity of an aqueous solution and is used to monitor changes in the concentration of dissolved minerals in water. It is one of the indicators for estimating water pollution by inorganic salts. Its size is proportional to the concentration of anion and cation in water, and is closely related to the dissolved solids in water. In order to understand the correlation between conductivity and dissolved solids, we started to monitor the conductivity and dissolved solids of the water body in the Gaoyao reach of the Xijiang River since 1986,

改革开放以来我国地方政府的制度创新空间不断拓展,由此形成的制度伦理问题也开始凸显,涵盖公正、平等、民主等价值元素的制度伦理的在场已经成为制度创新中不可回避的时代诉求。针对制度伦理建设中存在的诸如重经济轻其他、重效率轻公平、以强者为本等缺陷,我们必须在未来的制度创新中突出人民性、现代性、民族和区域性、合道德性等制度伦理元素,更好地促进制度伦理建设。
