투과전자현미경은 주로 시료의 내부구조나 단면을 관찰하는데 쓰이고 있다. 원리는 광학현미경과 비슷하다. 전자현미경에서의 광원은 높은 진공 상태(1x10-4 이상)에서 고속으로 가속되는 전자선으로 이 전자선이 표본을 투과하여 형광판이나 사진필름에 초점을 맞추어 투사된다. 이 전자의 파장은 가

균열발생 단계(Crack-Initiation Stage)
공업재료는 연성이며 제조한 상태대로는 균열이 존재하지 않지만, 일반적으로는 입자, 함유물 등을 포함하고 있다고 가정한다. 미시적 크기에서 금속은 균질하지도 않고 등방성도 아니다. 또한 기하학적으로 응력집중(노치)이 되는 부분이 있다
5.2 Drug Delivery System
5.2.1 Advantage of Nano-drug delivery system
By diagnosis, and for treatment, we need enhanced drug delivery system. Drug delivery system of these days is just eat and let it flow through the body. It is not good at efficiency. Because the digestive system sometimes digest and remove the drug before it reaches to the target.
For enhancing the efficiency of drug

<호흡의 필요성에 대한 부정적 견해>
- 호흡에 대한 특별한 치료가 필요치 않다 (Darley, Aronson, Brown, 1975).
