SI Units

基本解釋

Here is the value of using SI units.
這是使用國際單位制單位的好處。
And the constant, if we redo it in modern SI units, 1 would take on the value of 1.1 1*10^7m-1 times 10 to the 7th reciprocal meters.
如果我們用現(xiàn)代國際單位制來改寫它，這個值是1,1。
At the same time, the practice shows that the accuracy of fundamental SI units could be improved further by redefinition of some fundamental physical constants.
同時，實踐證明，用固定若干基本物理常數(shù)的數(shù)值來重新定義基本單位，可以進(jìn)一步提高基本單位的準(zhǔn)確性。

And the constant, if we redo it in modern SI units, 1 would take on the value of 1.1 1*10^7m-1 times 10 to the 7th reciprocal meters.
如果我們用現(xiàn)代國際單位制來改寫它，這個值是1,1。

But in terms of SI units, which become much more useful if you're actually trying to use intensity in a problem and cancel out your units, we're just talking about joules per second is what intensity is.
但是用國際單位制，這個變得越來越有用了,如果你實際上在使用強度,來解決問題和約化單位，我們僅僅討論每秒鐘的焦耳,這就是強度。

SI units means everything goes in, in SI, everything comes out in SI.
國際單位制單位意味著所有元素進(jìn)出，都是以國際單位制單位的形式。
