+# 工作流
+
+## 流程引擎后台变量
+
+* wfRt: IWorkflowRuntime类型
+* wf: IWorkflow类型
+* wfVars: IWorkflowVarSet类型，对应于`wf.getGlobalVars()`
+
+## 参数
+arg定义具有persist属性，如果设置为true，则会保存到wfVars集合中，存储到`nop_wf_var`表中。
+
+## 条件判断
+
+```xml
+<when>
+  <eq name="wfVars.day" value="${7}" />
+  <eq name="wfVars.day" value="@:7" />
+</when>
+```
+
+条件判断中值如果不是字符串类型，则可以用表达式语法或者前缀引导语法来标识数值类型。
