Waters has a long-term point of view and considers long-term growth, recently running a risk of a series of deficit rather than a short-term achievement.

(1) 열량계의 물당량 측정
전기 열량계에서 발생하는 열은 물뿐만 아니라 열량계에도 흡수된다. 열량 보존 법칙을 이용하여 열량계의 물당량을 먼저 구하자.

II. How is CBM formed
Coalbed methane (CH4) forms in one of two ways. During the earliest stage of coalification (the process that turns plant detritus into coal), biogenic methane is generated as a by-product of bacterial respiration. Aerobic bacteria (those that use oxygen in respiration) first metabolize any free oxygen left in the plant remains and the surrounding sediments. In fresh water
2.3 C-V graph
The measured MOS capacitance (called gate capacitance) varies with the applied gate voltage.
① Measurement of C-V characteristics
-Apply any DC bias, and superimpose a small (15 mV) ac signal
-Generally measured at 1 MHz (high frequency) or at variable frequencies between 1KHz to 1 MHz
-The dc bias VG is slowly varied to get quasi-continuous C-V characteristics

1. 실험 목표
이번 실험은 Airfoil 주위의 유동을 발생시켜 그로 인해 발생하는 항력(Drag), 양력(Lift) 등을 측정해 보는 실험이다. 여기서 실제 Airfoil의 크기를 축소하여, 모형 Airfoil을 사용, 동적상사(Flow similarity)를 이용하여 풍동실험을 한다. 각각의 받음각에 따라,
