捏不碎的鸡蛋作文

“ why should a lot of buildings build egg carapace record? ” is having 100 thousand why the little brother is pestering mom to ask again.

“为什么很多建筑要建成鸡蛋壳状?”有着十万个为什么的弟弟又在缠着妈妈问。

Because “ is globose solidder than any appearance! Do not believe, you hold an egg to try with the hand, how to also hold not pure? ”

“因为球形比任何形状都坚固呀!不信,你们用手捏鸡蛋试试,怎么也捏不粹?”

Have this kind of view unexpectedly, to mom's word I show intense suspicion: Small egg, touch good thing with respect to pure, hold how possibly not bad?

居然有这种说法,对妈妈的话我表现出强烈的怀疑:小小的鸡蛋,一碰硬的东西就粹,怎么可能捏不坏?

I and little brother take out an egg severally from freezer immediately, the decision wants personally test and verify. I hold the egg closely in control, can use up me all effort are holding it, but egg actually absolutely still, lie in my hand silently, seem to saying: What “ knows me is fierce, my case is powerful, you are held forever not pure. ”

我和弟弟立刻从冰箱里各自拿出一个鸡蛋,决定要亲自验证。我紧紧地把鸡蛋攥在手心里,可尽我所有的力气捏着它,可鸡蛋竟然纹丝不动,静静地躺在我手里,好像在说:“知道我的厉害了吧,我的壳强大的很,你永远捏不粹。”

“ our effort is too little, the hand is too little also, look for father to try. ” we give father from room lira, ground of too impatient to wait fills in the egg into father's hand. See father only one face is solemn, facial Dou Zhanggong, but egg all the same safe and sound ……

“我们力气太小了,手也太小了,找爸爸试试。”我们从房间里拉出爸爸,迫不及待地把鸡蛋塞进爸爸的手里里。只见爸爸一脸严肃,脸都涨红了,可鸡蛋照样安然无恙……

I 100 think of do not get its to solve, how can be the egg held not pure, be too mysterious really!

我百思不得其解,怎么鸡蛋会捏不粹了,真是太不可思议了!

In the side of father mother the composition is aided below, I opened small chicken egg abstruse close: Because the egg is round, hold the egg when control, the pressure that its surface place gets is equal, this pressure makes not quite chorion burst. Egg carapace is like this to bear greatly force, as peculiar as it egg form curve and scientific structural branch do not leave. The structure of the egg has three-layer, outer the cortex that it is a watch, middle-level is sponge layer, lining is tit layer, can bear so great pressure, because it can disperse the pressure that get equably to each parts of chorion,be. Have curvilinear appearance, ply very thin, basically bear the structure of pressure calls layer the structure on the building, the egg is typical shell structure. See in our life globose with vaulted building it is the shell structure with the egg cent does not leave, such building already beautiful solid and firm.

在爸爸妈妈的帮作文助下,我揭开了小小鸡蛋的奥密:因为鸡蛋是圆的,把鸡蛋捏在手心时,它表面所受的压力都是相等的,这个压力不够使蛋壳破裂。鸡蛋壳之所以有如此大的承受力,是与它特有的蛋形曲线和科学的结构分不开的。蛋的结构有三层,外层为表皮层,中层为海绵层,内层为乳头层,之所以能够承受这么大的压力,是因为它能够把受到的压力均匀地分散到蛋壳的各个部分。具有曲线的外形,厚度又很薄,主要承受压力的结构在建筑上叫薄层结构,鸡蛋就是典型的薄壳结构。我们生活中看到球形和拱形的建筑都是和鸡蛋的薄壳结构分不开,这样的建造既美观又坚实牢固。

Scientific force is really mystical, it is “ is taken care everywhere really all knowledge ” , small a chorion is like this unexpectedly big a large number of! Say like Einstein: “ science is never-ending, it is a lasting mystery. I decide ” hard to learn, go exploring, go opening the veil of scientific mystery!

科学的力量真是神奇呀,真是“处处留心皆学问”,小小一个蛋壳竟有如此大的大量!就像爱因斯坦说的:“科学是永无止境的,它是一个永恒之谜。”我决定努力学习,去探索,去揭开科学神秘的面纱!(文/龚智磊)
