Complete metrics tables for "Goal Question Metrics" modeling

The final step in GQM modeling was determining the 80 metrics in the multivocal literature to be used according to the raised questions. Each table lists the metric name, descriptions (when necessary) and the formulas or data that quantify them.

目标-问题-指标（Goal Question Metric，GQM）建模的最终步骤为：依据所提出的问题，从多源文献（multivocal literature）中确定需采用的80项指标。各表格均列出了指标名称、（必要时的）说明以及用于量化各项指标的公式或数据。
