我系为环境监测专业四年级学生讲授环境化学课过程中,分三个阶段渗入了一些计算机应用的内容。第一阶段,讲到水体中酸性物质的时候,布置了这样两道题: 1.已知二元弱酸H_2B的两级电离常数K_1,K_2,求算H_2B、HB~-、B~(2-)三种型体的分布系数α随pH值变化的通用计算机程序。 I am a fourth-year environmental monitoring major in environmental chemistry teaching course, in three phases into a number of computer applications. In the first stage, when it comes to the acidic substances in water, the following two questions are arranged: 1. The two-level ionization constants K_1 and K_2 of the binary weak acid H_2B are known, and H_2B, HB ~ -, B ~ ) The distribution of three types of body factor α with the pH value of the general computer program.
