The stateless execution of a task is to ensure that input to the task is the initial state and all final state related information is present in the output.
任务的无状态执行是为了保证任务的输入是初始状态,而所有与最终状态相关的信息都会存储在输出中。
The rest of the code is elementary. If no results are returned, set the status code to 0; otherwise, set it to 1. Output the initial XML, the XML for each message, and the final XML.
剩下的代码就相当基础,如果没有结果,就设置状态代码为0,否则,设置为1,输出最初的xml,每个消息的xml以及最终的xml.就是这些了,代码如下
One thing we should point out: looking back at Figure 1, the complete process consists of a sequence of activities between the initial and final nodes.
需要指出的一点是:请回头看一下图1,完整的流程由初始节点和结束节点之间的一系列活动组成。
So there's going to be a line that's going to connect the initial point to the final point, and that line mathematically is not going to be the same as this one here.
连接绝热过程,初末态的曲线的方程,和等温线的方程,也不会相同。
OK, so, the thing about a state function is that the function has a value for initial conditions and at final conditions.
态函数的特点是,在初始状态有一个值,在末状态也有一个值。
It's very interesting because velocity seems to require two different times to define it -- the initial time and the final time.
这非常有趣,因为速度似乎需要两个时间才能算出来,初时刻和末时刻
