风险的成本估算完成后，可以针对风险表中的每个风险计算其风险曝光度。某软件小组计划项目中采用50个可复用的构件，每个构件平均是100LOC，本地每个LOC的成本是13元人民币。以下是该小组定义的一个项目风险。  ①风险识别：预定要复用的软件构件中只有50%将被集成到应用中，剩余功能必须定制开发。  ②风险概率：60%。  ③该项目风险的风险曝光度是(33)。

SOX is an alternative (71) for XML. It is useful for reading and creating XML content in a (72) editor. It is then easily transformed into proper XML.

SOX uses (75) to represent the structure of an XML document, which eliminates the need for closing tags and a number of quoting devices. The result is surprisingly clear.

从数据库管理系统的角度看，数据库系统通常采用如图2-10所示的三级模式结构。图中①②处应填写(52)，③处应填写(53)。

某单位内部局域网中，客户机通过基于Windows操作系统的代理服务器访问Internet的连接方式如图 2-11所示。地址为192.168.1.100的客户机配置“TCP/IP网络属性”时，其中“网关”的设置内容应是(69)。该客户机访问Internet时，经由代理服务器后数据包的源地址为(70)。
