Alright, so it turns out there're two other useful types that you don't get for free out of the box.

Usually, these get charted out into the so-called overtones, thirty-two partials or overtones, and you can see them playing out here .

You can see that when you get out to the highest groups here, the highest weights, the relative risk is up at two and a half or three, so that would be a 200% increase in risk for cardiovascular death or two to three times the risk of death.
当我们看图上相对风险最高的这组,也就是体重最大的这组,这组的相对风险大约是2.5倍到3倍,即心血管疾病致死的风险增加了200%,或者说增加了2到3倍
That's a choice, and that choice turns out to be very interesting and really important, because if you connect these two points together, you get a straight line that has to intercept the x-axis at some point.

You can add something else to the answer without invalidating it, and that is anything with one power of t in it, because if you take one derivative it'll survive, but if you take two derivatives, it'll get wiped out.
你可以往答案后面加上其它东西,而且不影响结果,也就是任何t的一次项,因为你求一次导数之后它还在,但如果你求两次导数,这一项就不存在了
