“抗女计划”

我在心里暗暗发誓:男生将不再被女生欺负了,那些恶狼似的女生压迫男生的时代一定会成为过去的。虽然班上的女生各有千秋, 比如,杨妍婧会“九阴白骨爪”,     

堵车记

“吱嘎”一声,车停了。“八成又堵车了。”“好不容易通畅一会儿,怎么又堵了。”车里的人怨声载道,和着车外“叽叽”、“叭叭”的喇叭声,我的耳膜都要被震破了!我都要被烦死了!我默默念叨着:佛祖、观音菩萨、孙悟空、猪八戒、沙和尚……帮帮忙,快开车,我不能迟到啊!“我得下去看看。”前思后想,左思右想后,我大步走下车。哇!好壮观啊!真是前不见头后不见尾,是一条比长龙还长的“长长龙”。现在,这条“长长龙”正无精打采地趴着,只有“叽嘎”乱叫的力气,没有走的力气,甚至连爬的力气也没有。“这要堵到什么时候呀?照这样下去,我非迟到不可!”…     

Dynamic balancing of dual-rotor system with very little rotating speed difference

Unbalanced vibration in dual-rotor rotating machinery was studied with numerical simulations and experiments. A new method is proposed to separate vibration signals of inner and outer rotors for a system with very little difference in rotating speeds. Magnitudes and phase values of unbalance defects can be obtained directly by sampling the vibration signal synchronized with reference signal. The balancing process is completed by the reciprocity influence coefficients of inner and outer rotors method. Results showed the advantage of such method for a dual-rotor system as compared with conventional balancing.

我的节日

又一个早晨来临了,咕咚娃缩在被子里睡懒觉,妈妈在屋外叫他:“小懒虫,快起床,你知道今天是什么日子吗?"“什么日子?"棉被下打着哈欠的咕咚娃跟睛还睁不开呢。今天是……六月一日!一、—1‘ 弋～、 ～、} “呀啊!要迟到了!”随着一声 惨叫,咕咚娃一边穿衣服一边往外跑,在路上卷起了一阵戳愚可f /—、广\/ I ● ■J_-。、 砰!咕咚娃和迎面跑来的小猪撞在了一起。两个人被撞得晕头转向,眼冒金星,但还是很快地爬起来,一边嚷着:“没时间了!"一边赶紧往前冲。。V t∥’黧!—骶蒸毒一 _ √ 。j。j、 咕咚娃喘着气跑进了一删\学,回过神后,咕咚娃傻…
