Activities and their flows are the main abstractions and the data manipulated by the processes is essentially hidden in process variables.

Normally, variables are best named by their use (like firstName or title), but as this variable is essentially a loop counter, using single letters is also fine.
变量一般最好根据用途命名（如 firstName或rtitle），不过由于这个变量基本上是一个循环计数器，也可使用单个字母。
Essentially, optimal reactive power dispatch is the multi-restraint overall optimization problem with plentiful local minima and discrete variables.
从本质上讲，无功优化调度问题是具有大量的局部极小值的多约束全局优化问题，且含有大量的离散变量。
Assignment of variables in-template is essentially placing application logic into the presentation that may be better handled in PHP. Use at your own discretion.
在模板里为变量赋值本质上来说是为外观描述放置应用程序，一般来说变量赋值行为在php代码中操作比较好。不过，一切由你定夺。
The information is essentially"captured" by the closure allowing it to be referred to anywhere and anytime, even prior to the actual creation of the variables.
这些信息本质上被闭包所捕捉以使其在任一时刻任意地点都可以被引用。甚至在变量被实际创建之前。
