工艺流程题的内容往往与生产、生活实际联系密切,因此从题干部分看一般都是采取流程图的模式.(1)流程图的形式各异,有的以操作名称作为框图形成流程的主线,有的以物质作框,有的以设备作框,但每一题都固定某一种形式作框,从近几年的试题看常见的是以操作名称为主线,物质随着操作流程发生变化.(2)这类题目中通常还包含简单的实验设计,实验一般为制备或对样品的定性、定量分析实验.解题方法:关注流程“三线”(去线、进线和可逆线)和“核 The content of the process flow is often closely linked with the production and the actual life, so from the dry part of the general view are to take the flow chart mode (1) flow chart in different forms, and some with the name of the operation as a block diagram form the main line of the process , Some of the box for the material, and some equipment for the box, but each question is fixed in a certain form of box, from the questions in recent years to see the usual name is the main line of operation, the material occurs with the operation flow Change. (2) Such topics usually include simple experimental design, the experiment is generally for the preparation or sample qualitative and quantitative analysis of the experiment. Problem-solving methods: attention to the process ”three-line “ (to the line, into the line and reversible Line) and ”nuclear
