You might have expected to see the policy lookup primitive in the subflow, but actually that's currently not possible.
您可能期望在子流中找到策略查找原语，但目前来讲，这实际上是不可能的。Try to use built-in primitives instead of building your own construction out of an encryption algorithm and a hash function.
尝试使用内置原语而不是抛开加密演算法和杂凑函数去建构自己的构造。To see how these primitives might be used, consider an application with a server and a number of remote clients.
为了看清楚这些原语的可能用法，请考虑这样一个应用：它支持一个服务器和多个远程客户。This primitive is going to route the inbound message to one of two possible transformations.
此原语会将入站消息路由到两个可能的转换之一。Each XSL Transformation primitive is associated with a map file that describes the transformations to be made to the input XML.
每个XSLTransformation原语与描述要对输入XML进行转换的映射文件关联。For some run-time environments, it may be necessary to model synchronization primitives, but the system has been designed to make this easy.
对于某些运行环境，它可能需要建立同步原语模型，但系统设计非常容易。Understands kernel mode vs. user mode, multi-threading, synchronization primitives and how they're implemented, able to read assembly code.
了解内核模式vs用户模式，多线程，同步原语以及它们如何实现，能够阅读汇编代码。Now, let's explore some of the basic graphics primitives before digging into a couple of sample applications.
现在，我们来看一些基本的图形原语，然后再深入探讨几个示例应用程序。Work from left to right: first create the first primitive you intend to use and wire it up to the input node.
从左向右工作：首先创建您想要使用的第一个原语，并将其连接到输入节点。
