问题 多项选择题

设备安装前,应按照规范对设备基础的()进行复检验收。

A.混凝土强度

B.位置

C.平整度

D.几何尺寸

E.混凝土配比

答案

参考答案:B, D

解析:首先搞清题意,是安装前的复检,而不是第一次的基础验收,更不是对土建混凝土内在质量的审核,而是对与安装直接有关系的土建质量复检,以便使安装过程中不因土建的质量问题而影响正常安装。其次,分析与安装有直接关系和无直接关系的选项。选出有直接关系的,剔除无直接关系的。本题中基础标高位置及几何尺寸与安装直接有关,而混凝土的内在质量已在基础验收时确认,基础平整度对安装质量影响不大,因此即可确定此题答案。

It is important for your teen to eat a healthy, balanced diet during exam times to focus and do her best.   73    If this happens, encourage your teen to eat light meals or sandwiches. A healthy diet, rather than junk food, is best for reducing stress.

  74   Persuade your teenager to get some sleep and /or do something active when she needs a real break from studying. Making time for relaxation, fun, and exercise are all important in reducing stress. Help your teen balance her time so that she will feel comfortable taking time out from studying to spend time with friends or rest.

Show a positive attitude.   75  Your panic, anxiety and blame contribute to your teen’s pressure. Make your teen feel accepted and valued for her efforts. Most importantly, reassure your teen that things will be all right , no matter what the results are.
