1.终极密码推荐指数:★★★规则:猜数字每猜一次范围缩小,最后猜中的人倒霉挨罚。
先由一个人给出一个数字的范围(比如1~100),在此范围内写一个数字,保证不让其他人看到。
然后大家在范围内猜测他写的数字是多少,尽量避免猜中此数。
每猜一次范围缩小,最后猜中的人进行抽签接受这份大奖。
下一轮由受罚者再写数字,依此循环。
2、“我爱你,你爱我吗”推荐指数:★★★★游戏规则:大家围成一个圈,一个人站圈内,随机对队伍中的一个人说“我爱你,你爱我吗”,如果对方回答“我也爱你”,则回答者左右两个人与圈子中间的人要抢占回答者左右的两个位置,三人中没有抢到的出局;如果回答者说“我不爱你”并且随手指出爱的对象说“我爱他”,被指者左右两个人与圈子中间的人要抢占回答者左右的位置,三人中没有抢到的出局。
如果回答者说“我不爱你”还有一种选择,可以说“我爱今天穿白衣服的人”之类的问题,那么所有穿白衣服的人要和圈内的那人一起抢位子。
没抢到位子的人出局。
出局的人成为下一轮的圈内人。
3、逛三园推荐指数:★★★游戏规则:1)大家围一圈。
从一人开始边拍手边说:“星期天,逛三园——水果园。
”(拍手速度要快)例:大家说的顺序:A星期天逛三园水果园(也可以说蔬菜园或动物园)B苹果(对应A所说的园)C梨。
2)直到由某个人拍两次手后还未反应过来,没有说出相应的东西,或者说出的东西与前面人重复,则就应受惩罚。
要素:集中注意力反应能力4、比划猜成语推荐指数:★★★游戏者排成一列,由主持人把要猜的成语拿给最后一个人看,然后他再让前面一个人转过身来看他比划,不许出声。
这样一直到最后一个人。
答案正确且最快的一队获胜。
每组派出两名队员到其他组作裁判。
5、谁是卧底推荐指数:★★★★游戏规则:以8人游戏(不包括出题法官)为例,其他人数配置请参见下文。
1、在场八人中6人拿到同一词语,剩下2人拿到与之相关的另一词语。
这时平民与卧底都不知道互相的身份,卧底也不知道自己是卧底。

计算6.纯Cu 的空位形成能是1.5aJ/atom(1aJ=10-18J),将纯Cu 加热到850℃后激冷到室温(20℃),如果高温下的空位全部保留,试求过饱和空位浓度与室温平衡空位浓度的比值。
(玻尔兹曼常数K=1.38×10^-23J /K )简述7.铸件组织有何特点?答案:在铸锭组织中,一般有三层晶区:(1)最外层细晶区。
其形成是由于模壁的温度较低,液体的过冷度交大,因此形核率较高。
(2)中间为柱状晶区。
其形成是由于模壁的温度升高,晶核的成长速率大于晶核的形核率,且沿垂直于模壁风向的散热较为有利。
