生活中有什么科学小常识？ （英汉双语翻译意思及用法例句-英汉词典）

生活中有什么科学小常识？

有很多科学小常识可以帮助我们更好地生活。1.例如我们经常使用的冰箱，把它放置在室内的一个角落，靠近墙壁，可以帮助降低电费，因为这种放置方式可以让室内温度更低，让冰箱的制冷效率更高。2.除此之外，我们在洗碗的时候，不要用过热过冷的水，因为过热或过冷的水会对碗盘有损害，同时也容易烫伤我们自己。适宜温度的水可以减少对碗盘的损伤，同时更加健康可靠。3.我们的衣服经常让它们晾在室外，因为阳光会在一定程度上消毒晾晒的衣服，让我们的衣服更干净、健康。另外也可以降低使用烘干机的频率，减少电费开销。

生活中的科学小常识？

1.

维生素C含量丰富的食物不能和海鲜一起吃。因为维生素C有还原性，海鲜类具有砷含量较高,因为这些海鲜中的砷会同维生素C反应,维C具有还原性,之后生成的五氧化二砷有剧毒。

2.

向日葵的茎部含有一种奇妙的植物生长素。这种生长素非常怕光。一遇光线照射，它就会到背光的一面去，同时它还刺激背光一面的细胞迅速繁殖，所以，背光的一面就比向光的一面生长的快，使向日葵产生了向光性弯曲。因此向日葵总是向着太阳。

生活中的科学小常识谢谢？

 当然可以！生活中有很多科学小常识，以下是一些常见的例子：

1. 为什么肥皂泡总先上升后下降？

肥皂泡上升的原因是内部气体的密度小于外部空气的密度，根据阿基米德原理，肥皂泡受到的浮力大于重力。随着上升过程的进行，肥皂泡内气体温度下降，体积逐步减小，受到的外界空气浮力也会逐步变小，最终导致肥皂泡下降。

2. 为什么热水泡腾片剂更容易溶解？

热水中的热量能加速分子运动，提高溶解度，使泡腾片剂中的药物成分更快地溶解在水中。

3. 为什么鸡蛋煮熟后蛋白变硬，蛋黄变软？

鸡蛋煮熟后，蛋白中的蛋白质凝固，形成了紧密的结构，从而变得坚硬。而蛋黄中的蛋白质含量较低，加热后不易凝固，因此蛋黄相对较软。

4. 为什么镜子里的反射图像左右颠倒？

镜子里的反射图像左右颠倒是因为光线在经过反射时，传播方向发生了改变。当我们观察镜子里的图像时，实际上是在观察光线反射后的方向，因此呈现左右颠倒的现象。

5. 为什么咖啡伴侣能漂浮在咖啡上？

咖啡伴侣中的成分（如植物油、糖等）的密度小于咖啡，因此能漂浮在咖啡表面。此外，咖啡伴侣颗粒之间的空隙能容纳气体，使它们具有较好的浮力。

6. 为什么湿衣服在阳光下干得更快？

湿衣服在阳光下干燥的速度更快，是因为阳光能提高衣服的温度，加速水分的蒸发。同时，阳光中的紫外线还能杀死细菌，使衣物更干净。

7. 为什么音乐能缓解压力？

音乐能缓解压力是因为音乐中的旋律和节奏能刺激大脑释放内啡肽等“快乐激素”，从而达到舒缓心情、减轻压力的作用。

这些生活中的科学小常识帮助我们更好地理解周围的现象，也使我们的生活更加丰富多彩。希望这些信息能对你有所帮助！

What science little common sense is there in the life?

Very much scientific little common sense can help us live better. 1. For example the refrigerator that we often use, place it indoors a corner, stand by wall, can help reduce charge of electricity, because this kind places means to be able to make indoor temperature lower, the refrigeration efficiency that lets freezer is taller. 2. Besides, when we are washing a bowl, do not use the water of overheat super-cooling, can be opposite because of the water of overheat or super-cooling bowl dish have damage, at the same time ourselves of easy also scald. The water of appropriate temperature can reduce pair of bowls dish injury, at the same time more healthy and reliable. 3. Our dress often lets their air be outdoor, because sunshine is met,the clothes that air dries is disinfected on certain level, the dress that lets us is cleaner, healthy. Also can reduce the frequency of use dryer additionally, reduce expense of charge of electricity.

Does science give birth to vivid small doohickey?

Good, sure, I will to you share a few economic science to give birth to vivid small doohickey.

Encounter radial illuminate, it can go to the one side that be in a poor light, at the same time it returns stimulation to be in a poor light the cell of one side breeds quickly, so, what grow what compare Xiang Guang at the same time what be in a poor light at the same time is fast, make helianthus produced phototropism to bend. Because this helianthus always sides with the sun.

Does the scientific Xiaochang in the life know a thank?

 OK of course! There is very much scientific little common sense in the life, it is a few common example below:

1.Why lathery after always rising first, drop?

Lathery the density that ascendant reason is in-house gas is less than exterior airy density, according to the Archimedes's principle, lathery the flotage that get is more than gravity. As ascendant process undertake, lathery inside aeriform temperature drops, bulk is reduced stage by stage, the outside air flotage that get also is met progressively decrescent, bring about finally lathery drop.

3.Why the albumen after the egg is thoroughlied cook hardens, yoke molten?

After the egg is thoroughlied cook, the protein in albumen is caky, formed close together structure, become hard thereby. And the protein content in yoke is inferior, after heating not easy and caky, because this yoke is opposite softer.

4.Why does the reflection image in the mirror control reverse?

Because the light is when course reflex,the reflection image left and right sides in the mirror is topsy-turvy, transmission way produced a change. When we observe the image in the mirror, it is the direction after observing the light is reflexed actually, because this presents the appearance of or so reverse.

5.Why can coffee spouse float on coffee?

The composition in coffee spouse (wait like vegetable oil, candy) density is less than coffee, because this can float in coffee surface. In addition, the space between coffee spouse grain can contain gas, make they have better flotage.

6.Why does wet dress work more quickly below sunshine?

The rate with wet dry below sunshine dress is rapidder, because in relief light energy raises the temperature of the dress,be, quicken what water divides to evaporate. In the meantime, the ultraviolet ray in sunshine still can kill a bacterium, make clothings cleaner.

7.Why can music alleviate pressure?

Music can alleviate because the air in music and rhythm can stimulate cerebrum to release,pressure is inside Fei peptide " happy hormone " , achieve thereby slow the mood, action that eases pressure.

What does science exercise little common sense to have?

Science exercises little common sense to include: Reasonable arrangement exercises time and intensity, avoid excessive exhaustion and get hurt; Choose those who suit oneself to exercise means and place, if training of oxygen motion, force, gem gal waits; Notice dietary nutrition, make sure the body can bear exercise bear; Increase carry momentum and strength gradually, avoid to increase negative charge suddenly; Maintain good posture and breathing pattern, exercise effectively each part muscle.
