工艺上M10的螺纹（8.8级）紧固扭矩范围在（）N.mm。A、30-40 B、20-3

(一)

某新建办公大楼的招标文件写明：承包范围是土建工程、水电及设备安装工程、装饰装修工程；采用固定总价方式投标，风险范围内价格不作调整，但中央空调设备暂按120万元报价；质量标准为合格，并要求创省优质工程奖，但未写明奖罚标准；合同采用《建设工程施工合同(示范文本)》(GF—99—0201)。

某施工单位以3260万元中标后，与发包方按招标文件和中标人的投标文件签订了合同。合同中还写明：发包方在应付款中扣留合同额5%，即163万元作为质量履约保证金，若工程达不到国家质量验收标准，该质量履约保证金不再返还；逾期竣工违约金每天1万元；暂估价设备经发承包双方认质认价后，由承包人采购。

合同履行过程中发生了如下事件：

事件一：主体结构施工过程中发生了多次设计变更，承包人在编制的竣工结算书中提出设计变更实际增加费用共计70万元，但发包方不同意该设计变更增加费。

事件二：中央空调设备经比选后，承包方按照发包方确认的价格与设备供应商签订了80万元采购合同。在竣工结算时，承包方按投标报价120万元编制结算书，而发包方只同意按实际采购价80万元进行结算。双方为此发生争议。

事件三：办公楼工程经四方竣工验收质量为合格，但未获得省优质工程奖。发包方要求没收163万元质量保证金，承包人表示反对。

事件四：办公楼工程实际竣工日期比合同工期拖延了10天，发包人要求承包人承担违约金10万元。承包人认为工期拖延是设计变更造成的，工期应顺延，拒绝支付违约金。

问 题

中央空调设备在结算时应以投标价120万元，还是以实际采购价80万元为准？说明理由。

Dear Guys,

I’d like to talk to you about the shame you subjected me to last night. Let me first refresh your memory: You, a group of fit, young men, were playing soccer on the field across from my apartment building. I, a better-than-average looking young woman, was walking along the sidewalk with my groceries. That’s when your ball came flying over the fence and landed in front of me.

One of you approached and asked politely if I would throw the ball back to you. Fighting the urge to drop my bags and run screaming down the street, I reluctantly (勉强地) agreed.

Before I continue, let me explain something that I didn’t have a chance to mention last night: I hate sports. More specifically, I hate sports involving balls. This results from my lack of natural ability when it comes to throwing, catching and hitting. I’m bad at aiming too. So you can understand why I’d be nervous at what I’m sure seemed to you like a laughably simple request.

However, wanting to appear agreeable, I put my bags down, picked up the ball and, eyes half-shut, threw it as hard as I could.

It hit the middle of the fence and bounced back to me.

Trying to act casually, I said something about being out of practice, then picked up the ball again. If you’ll remember, at your command, I agreed to try throwing underhand. While outwardly I was smiling, in my head, I was praying, Oh God, oh please oh please oh please. I threw the ball upward with all my strength, terrified by what happened next.

The ball hit slightly higher up on the fence and bounced back to me.

This is the point where I start to take issue with you. Wouldn’t it have been a better use of your time, and mine, if you had just walked around the fence and took the ball then? I was clearly struggling; my smiles were more and more forced. And yet, you all just stood there, motionless.

Seeing that you weren’t going to let me out of the trouble, I became desperate. Memories of middle school softball came flooding back. I tried hard to throw the ball but it only went about eight feet, then I decided to pick it up and dash with ball in hand towards the baseline, while annoyed thirteen-year-old boys screamed at me that I was ruining their lives. Children are cruel.

Being a big girl now, I pushed those memories aside and picked up the soccer ball for the third time. I forced a good-natured laugh while crying inside as you patiently shouted words of support over the fence at me.

“Throw it granny-style!” one of you said.

“Just back up a little and give it all you’ve got!” another offered.

And, most embarrassing of all, “You can do it!”

I know you thought you were being encouraging, but it only served to deepen the shame.

Anyway, I accepted your ball-throwing advice, backed up, rocked back and forth a little, took a deep breath and let it fly.

It hit the edge of the fence and bounced back to me.

I surprised myself-and I’m sure you as well-by letting out a cry, “DAMN IT!!!” I then willed myself to have a heart attack and pass out in front of you just so I’d be put out of my misery.

Alas, the heart attack didn’t happen, and you continued to look at me expectantly, like you were content to do this all night. I had become a sort of exhibition for you. I could feel your collective thoughts drifting through the chain-link: “Can she really not do it? But I mean, really?”

Unfortunately for you, I wasn’t really game to continue your experiment. Three failed attempts at a simple task in front of a group of people in a two-minute period was just enough blow for me for one night. I picked up the ball one last time, approached the fence and grumbled, “Please just come get the damn ball.”

And you did. And thanks to you, I decided at that very moment to never throw anything ever again, except disrespectful glances at people who play sports.

Sincerely, Jen Cordery

产生冷拉强化的原理是：钢材在塑性变形中晶格的缺陷增多，而缺陷的晶格严重畸变对晶格进一步滑移将起到阻碍作用，故钢材的屈服点提高，塑性和韧性降低。由于塑性变形中产生了内应力，故钢材的弹性模量降低。( )
