单选题You are the desktop administrator of your company’s network. You install a print device on a Windows XP Professional computer. This print device should be used only by the desktop administration staff and by managers. You share the printer on the network as DTA-Print and assign Allow - Print permissions to the DTA-S group, which includes staff members’ accounts, and the DTA-M group, which includes managers’ accounts. Later, the managers report that they must wait a long time for their jobs to print. You discover that the desktop administration staff generates many problematic print jobs. As a result, the managers’ print jobs must wait a long time in the print queue. You need to ensure that the managers’ print jobs print as quickly as possible while minimizing hardware costs. What should you do?（）A
Install a second printer for the same print device on the Windows XP Professional computer. Share this printer as DTA-Manager, and grant Allow - Print permission to the DTA-M group only. Configure a priority setting of 1 on DTA-Print. Configure a priority setting of 99 on DTA-Manager.B

单选题综合热分析法分析矿物时，以下分析参考的基本规律不正确的有（）A
产生吸热效应并伴有质量损失时，一般是物质脱水或分解；产生热效应伴有质量增加时，为还原过程B
产生吸热效应而无质量损失时，为晶型转变所致；有吸热效应并有体积收缩时，也可能是晶型转变C
产生放热效应并伴有体积收缩，一般为重结晶或有新物质生成D
没有明显的热效应，开始收缩或膨胀转为收缩时，表示烧结开始。收缩越大，烧结进行得越剧烈
