问题 单项选择题

直接影响幕墙节能效果的指标是()。

A.风压变形性能  

B.水密性能  

C.防火性能  

D.气密性能 

答案

参考答案:D

解析:

这是一道质量管理的题,主要考核建筑幕墙节能性能质量控制的知识点。对于具备一定现场实践经验的考生,此题不难。

幕墙的三项主要物理性能(抗风压、气密、水密)是互相关联、互相影响的指标,其中气密性是直接影响幕墙节能效果的指标。

建筑幕墙设计都必须规定工程的气密性能的等级。与一般幕墙工程“三性试验”要求不同的是,幕墙节能工程的气密性试验,除了需提供常规的试验报告外,对幕墙面积大于3000m2或建筑外墙面积50%的工程,还要求在现场抽取材料和配件,在检测试验室安装试件进行气密性能检测。检测结果应符合设计规定等级的要求。

故本题的正确选项应为“D.气密性能”。

考点:

Some children are born bosses. They have a need to make decisions, manage their environment and lead rather than follow. Too much rule in the hands of the young isn’t healthy for children or the family. Family expert John Taylor says, “Children have secret feelings of weakness. They are always trying to feel safe. ”It’s the parents’ duty-not the child’s-to provide safety.

When a “boss child’’ doesn’t learn limits(限制)at home, troubles will appear outside the family. The child may have trouble obeying(遵守)teachers, for example, or keeping friends. It can be pretty lonely as the top dog if no one likes your ruling ways.

Bossy kids are often unusually bright. Their parents need to be especially careful to manage them. Bossy kids usually work more on the mother. It’s important for both parents to know their child’s weakness, to agree on key rules and to back each up.

Even as you try to be kind—to a point—don’t give up your parental ruling post. Instead, stand your ground by using body language that tells your child who the boss is.

Good manners are important to family. Show a child by example how to ask for something rather than shout orders. Try asking your child to do things that are not too difficult. Then reward(奖励)him with a hug(拥抱)and words such as “Thank you. I like it when you listen to me.” Over time good manners will become associated(联结)with pleasure.
