生活中的冷知识你知道多少？
1、黄金的K是什么意思？
商业上是用K来代表含金合金的金含量，含有黄金的合金就被称为K金，在英文中是Karat Goal，简称K。这种含量就是表示将单位的纯金分成24等份，用数字来表示金的比例。
24K就是24.24，即含金量100%，为足金；18K就是含金18.24，即75%，14K为58.33%，12K为50%。除了金以外，K金另外的金属是铜和银，这些金属的比例适当，K金显示出漂亮的光泽。
2、方便面是哪国人发明的？
众所周知，方便面是日本人安腾百福发明的。其实安腾百福是华裔，原名吴百福，祖籍台湾。
安腾百福自幼父母双亡，1932年用继承的遗产做纺织生意；1948年加入日本国籍，并建立中交总社做制盐生意，这就是日清食品的前身。安腾很早就有研制方便面的想法。在1957年生意破产之后，他在自己家的庭园中建了小房以研究方便面条。1958年8月25日，世界上第一个方便面——鸡肉拉面诞生了。
后来，安腾又发明了杯面。2005年，95岁高龄的安腾百福退休。2007年，他因心脏病去世。他的发明被称为20世纪最伟大的发明之一。
3、为什么彩条牙膏不会被挤乱呢？
彩条牙膏为什么总是保持很整齐的颜色分隔呢？乱挤牙膏为什么也不会把它搞得颜色混乱？
原来，彩条牙膏在生产时，膏体的颜色就已经固定好比例被灌进去，它的截面就是一个圆，被等分挤出来时，牙膏口在中间，所以膏体一起往上运动，在很细的出口处被拉伸，几种不同颜色的膏体绞扭在一起。虽然整体上来看牙膏颜色是混乱的，但刷牙的时候一般只截取很短的一段，也就看不出乱来。所以，彩条总是以十分整齐地样子躺在我们的牙刷上。
4、为什么下午摘的玫瑰更能持久？
如果你希望亲手摘下一朵满带晶莹晨露的玫瑰送人，建议你最好放弃，不如选择在下午再去摘下它，因为这样可以更长时间地看到这朵花。
一般来说，下午摘下的玫瑰比清晨摘下的玫瑰更能持久，不易枯萎。这是因为，经过大半天阳光照射的玫瑰，其体内在下午时含有的二氧化碳浓度低得多，使之呈中性或者弱碱性，更不容易腐败，花瓣内的色素也更稳定、持久。
English translation:
1. What does the K in gold mean?
Commercially, K is used to represent the gold content of gold-containing alloys. Alloys containing gold are called K gold, which is Karat Goal in English, or K for short. This content means that the unit of pure gold is divided into 24 equal parts, and the proportion of gold is represented by numbers. 24K is 24.24, that is 100% gold, which is pure gold; 18K is gold containing 18.24, which is 75%, and 14K is 58.33% , 12K is 50%. In addition to gold, the other metals of K gold are copper and silver. The proportion of these metals is appropriate, and K gold shows a beautiful luster.
2. Who invented instant noodles?
As we all know, instant noodles were invented by the Japanese Itanium Momofuku. In fact, Itanium Pak Fook is of Chinese descent, formerly named Wu Pak Fook, and his ancestral home is Taiwan.
Itanium Pakfook's parents died since childhood. In 1932, he used his inherited inheritance to do textile business; he became a Japanese citizen in 1948 and established the China Communications Headquarters to do salt business. This is the predecessor of Nissin Foods. Itanium had the idea of developing instant noodles early on. After the business went bankrupt in 1957, he built a small house in his garden to study instant noodles. On August 25, 1958, the world's first instant noodle-Chicken Ramen was born. Later, Itanium invented cup noodles. In 2005, 95-year-old Itanium Pakfook retired. In 2007, he died of a heart attack. His invention is called one of the greatest inventions of the 20th century.
3. Why won't the color bar toothpaste be squeezed?
Why does color strip toothpaste always maintain a neat color separation? Why doesn't squeezing toothpaste make it messy?
It turns out that when the color bar toothpaste is produced, the color of the paste has been poured in at a fixed proportion. Its cross section is a circle. When it is squeezed out equally, the toothpaste mouth is in the middle, so the paste moves upward together. The very thin exit is stretched, and several different colored pastes are twisted together. Although the color of toothpaste is chaotic on the whole, when brushing teeth, only a short section is usually cut, and the chaos is not seen. Therefore, the color bars always lie neatly on our toothbrushes.
4. Why do the roses picked in the afternoon last longer?
If you want to pick a rose full of crystal morning dew and give it away, I suggest you give it up. It is better to pick it off in the afternoon, because you can see the flower for a longer time. Generally speaking, roses picked in the afternoon will last longer than those picked in the morning and will not wilt easily. This is because roses that have been exposed to sunlight for most of the day have a much lower concentration of carbon dioxide in their bodies in the afternoon, making them neutral or weakly alkaline, less prone to corruption, and the pigments in the petals are more stable and lasting. ——谷歌翻译
