RRD is the main type of retina disease .

RRD是视网膜脱离的主要类型之一。

RRD and PVR can be studied by using animal models.

借助于动物模型可以更好地进行此类疾病防治方面的研究。

Example 4 builds upon Example 3 and also demonstrates how RRD can be extended using the RRD Extension Generator and Handler frameworks.

示例4构建在示例3 基础之上，并且还演示了如何使用RRD扩展生成器和处理程序框架扩展RRD。

This is performed via the HMC and is covered in the lpar2rrd setup guide.

这通过HMC执行，lpar2rrd设置指南说明了具体步骤。

Example 1 is an RRD equivalent of the often-used Hello World application.

示例1是通常使用的“Hello World”应用程序的RRD等效项。

The extension handler chain is executed upon receiving a RRD request by calling each extension handler that matches some extension data that is attached to the RRD request.

扩展处理程序链在接收RRD请求时执行，方法是调用每个与附加到RRD请求的某些扩展数据匹配的扩展处理程序。

An RRD extension consists of an extension generator and extension handler pair.

RRD 扩展由扩展生成器 和扩展处理程序 对组成。

This chain is executed upon receiving an RRD request by calling the doHandle method on each extension handler that matches the qualified name of some extension data attached to the RRD request.

在接收到RRD请求时通过调用每个扩展处理程序（与附加到RRD请求的一些扩展数据的限定名称匹配）上的doHandle方法来执行此链。

The final example is independent of the others and demonstrates how RRD can be extended to support portlets.

最后一个示例与其他示例无关，它演示如何扩展 RRD 以便支持 Portlet。

This example builds upon the applications in Example 2, demonstrating the use of dynacache in an RRD request. To install and run the example

此示例构建在示例 2 中的应用程序之上，并演示如何使用 RRD 请求中的动态缓存。
