4.1. Wing structure
Wing structure
The wing on the plane is a part that the highest load take. The large bending moments especially act on the point near the root of wing. Also, we should consider the number of spar, rib, position, skin thickness and taper ratio.
I Beam shape

Beam theory shows that the I-shaped section is a very efficient form f
● Definition of plasma
Plasma is one of the four fundamental states of matter, along with solid, liquid, and gas. It is an ionized gas consisting of a collection of charged particles, including ions, electrons, and neutral atoms or molecules. Plasma can be found naturally in the universe in the form of stars, lightning, and auroras, but it can also be artificially created and controlled for

질소가스가 생체의 구성분으로 들어가기 위해서는 미생물의 작용이 필요하며, 동식물체로 들어온 질소가 다시 대기 중으로 돌아가기 위해서는 탈질이라는 과정을 거쳐야만 하고 이 과정의 대부분은 미생물의 작용에 의해서 일어난다.
최근 도시화와 산업의 발달, 자동차 공해 등은 자
