Half the people with this condition die within ten to fourteen days.

Now, the reason this condition always holds in ordinary mechanics is because you're never, in that case, concerned with a huge statistical population of particles where the disorder among them is an issue.
这个条件在力学中总是成立,这是因为在力学中,我们从来没有关注过大量粒子的统计行为,而对这些系统来说,无序是很重要的。
We have a couple of passages, one in the book of Numbers, one in the book of Job, which describe this condition in a way that identifies it with death. An aborted fetus is often not often, it happens once in the book of Job.
有两篇文章,一篇在《民数记》,一篇在《约伯记》里,描述了这种,意味着死亡的状况,比如说,一个被流产掉的胎儿就,但这些例子不多,只在《约伯记》里出现了一次。
I differentiate a second time and check the sign, so the second order condition, I differentiate this expression again with respect to q1.
我们对它进行二次求导然后看符号,这个式子的二阶导数,就是一阶导数再对q1进行求导
So in other words, if you terminate these lines early, if you terminate the four loop early, if you terminate an if condition early with that semicolon, the code may very well work; and this is a common source -- of frustration and conundrum because you don't -- because your code looks right and yet it's misbehaving, but that semicolon means stop looking for subsequent lines of related code.
换句话说,如果你用分号过早的终止了这些代码行,如果你过早地终止了那个for循环,如果如此,一个if条件,代码可能可以运行,这就是,挫折和问题产生的源头,因为你没有-,因为你的代码看起来是正确的,但是运行是错误的,那个分号的意思是,停止寻找后面相关的代码。
