The relationship between I and S

I spent whole day trying to find the relationship between I and S. I discuss with Gang. What I know for sure is $I(q) = KP(q)S(q)$. So I need to find the form factor of our system. The polymer is considered as a curve cylinder. I’ve tried my best maybe.

I played games with Lee and Ya. Besides, I want to talk to Nana, but I don’t know what to say, so I didn’t call her. I’m afraid of the bad temper of her.

“The only way to be happy is to be you.” I heard the sentence yesterday.
