A combined fragment is used to group sets of messages together to show conditional flow in a sequence diagram.
一个组合碎片用来把一套消息组合在一起，在一个序列图中显示条件分支。
Once I had decided what the underlying conditional flow would be, the only remaining task was to construct objects that would fit into this sequence of actions.
在确定底层的条件流程之后，剩下的惟一任务就是构建适合以后使用的对象。
This flow may either be conditional or unconditional; that is, there may be rules that specify conditions that must be met in order for the next activity in the process to be executed.
这个流向可能是有条件的也可能是无条件的；也即，可能有一些指定条件的规则，要执行流程中的下一个活动必须满足这些规则。
It greatly enhances the build process by letting you control program flow with looping constructs and conditional logic.
它让您用循环构造和条件逻辑控制程序流，极大地增强了构建过程。
A conditional connection executes the control flow only if this operation is successful.
这个有条件连接只在这个操作成功的情况下执行控制流。
For example, if you require more complex conditional logic, cyclic flow, compensatory capabilities, persistence of state, or in-process human interaction.
比如，如果需要较复杂的条件逻辑、循环流程、补偿功能、状态的一致或是过程中的人机交互。
Generic sequence diagrams make use of conditional logic, which can be useful for describing the alternative flow of events over the course of an interaction.
常规序列图利用了条件逻辑，这对于描述交互过程中事件的可选流程来说很有用处。
The palette also includes basic programming constructs that allow for controlling the flow, such as decision points for conditional execution, and loops for process cycles.
选项板也包括了控制流所需要的基本编程结构，例如有条件执行的决策点和流程周期的循环。
Much of the expressiveness comes from there being tags for conditional logic, dynamically changing the input model, and controlling the flow of execution.
表现力大多源于存在条件逻辑、动态更改输入模型和控制执行流的标签。
Structured activities: for managing the overall process flow for sequencing of activities, parallel processing of activities, and adding conditional logic in controlling the process flow.
结构化活动(Structured activity)：用于管理活动序列的整个流程流、活动的并行处理以及在控制流程流时添加条件逻辑。
In the previous picture, you can recognize some logical constructs that help with structuring the flow with conditional execution (the Switch activity) and with cycles (the Loop).
在前面的图中，您可以辨认出一些逻辑结构，这些结构可以使用有条件执行(Switch活动)和周期(Loop)帮助构建此流。
If, Else if, and Else refinements are conditional transforms used to control the flow of mappings within a map.
Elseif和Else细分是一些条件转换，用于控制映射内的映射流。
Connect the first data flow operator to the second using the green check mark in the upper right corner to make a conditional connection.
使用右上角的绿色对勾把第一个数据流操作符连接到第二个，这会建立有条件连接。
