1. 인장시험의 정의
재료시험에는 정적시험, 충격시험, 크립프 시험, 피로시험, 공업적 시험 등 여러 가지 시험이 있다. 그 중에서 정적시험에 속하는 인장시험(Tensile test)은 재료의 강도를 측정하는 가장 기본적인 시험으로 재료의 인장력에 대한 탄성적 성질, 소성변형 저항 및 파단강도를 측정하는
D.J.’s and bands. And for an indie scene more concerned with listening to the music than moving to it, Six D.O.G.S. is one of the few downtown places where people take to the dance floor en masse.
The artistic director, Konstantinos Dagritzikos, who plays drums in the ’60s-influenced band Love Beverly, says he tries to maintain a balance between booking local independent bands and acts from

Michael Grätzel Professor at the Swiss Federal Institute of Technology in Lausanne, Switzerland. Michael Grätzel directs there the laboratory of photonics and interfaces. His laboratory initiated studies in the domain of nanocrystalline semiconductor particles and mesoporous oxide semiconductor films. These systems are applied in a variety of fields, e.g. biosensors,electrochromic
