. 결정화의 기본 개념
결정화(Crystallization)란 분리기술의 일종으로 액체 혹은 기체의 균일상으로부터 조작을 통하여 고체입자, 즉 결정(Crystal)을 얻는 것을 말한다. 우리주의의 실생활에서 자연발생적으로 결정화 현상을 볼 수 있는 데 이것이 바로 눈(snow)의 경우이며 또한 바닷물을 증발시켜 소금을

□ Composition Analysis
Al, Si is almost insoluble to each other at rsoom temperature.
All solid phase will have either 100% Al phase or 100% Si phase.
The atmosphere shields us from the sun's cancer-causing ultraviolet (UV) radiation and also moderates the earth's climate.
The atmosphere is obviously vital for human existence, but we have nevertheless been polluting it for years.

결론) 1. Sampling Bottle의 Size에 따른 Particle 수준 확인 → Bottle Size에 대한 유의차 없음, 동일한 Size의 Bottle의 경우 (동일 조건)에도 변동 발생함
(추정 : Bottle Size가 작을 수록 Sampling 時 Bottle 벽에 부딪혀 생긴 Micro Bubble로 인하여 Particle 개수가 높을 것이다. But, 결론은 유의차 無)
2. Valve Open 정도에 따른 Part
distribution channel is increasing as well as market share of retail phase. Market share of big marts expects to be expanded due to continuous increasing quantity of imported rice, and it will be affected in not only rice producers and rice processing comples (RPC), but also competing distributors, such as wholesale market and small-sized retailers.
