1-3. 최적 압축비 이상으로 증가할 때 오히려 크랭크 축으로 전달되는 torque가 감소하는 이유 ?
압축비를 증가시킴으로써 엔진의 효율을 상승시킬 수 있다. 그러나 압축비를 무한정 높이지 못하는 원인들이 있는데 가솔린 엔진에서 압축비 제한의 가장 주요한 요인은 knocking이다.

indicates the potential barrier in the semiconductor.
Electric field to pass only because the atomic distance, metal within the energy - band is not observed any change in the diagram. In conclusion, the energy barrier for electrons in metals, respectively, is independent of the semiconductor doping and applied bias.
Reverse Bias
Now we can consider the effects forward bias s
indicate that 81.5% of the population is Russian. Tatars constitute 3.8%; Ukrainians make up 3%; Chuvash form 1.2%; Bashkir account for 0.9%; Belarusian for 0.8%; Moldavian for 0.7%; and a wide variety of other peoples are represented in the remaining 8.1%.
5) Ethnic Group
The modern Russian is formed from two groups, Northern and Southern, which were made up of Kriviches, Ilmen Slavs, Radimic
In catalyst, oxygen produced from H202
With sodium hydroxide, luminol Dianion is formed
The oxygen reacts with luminol dianion
This product is very unstable, so decomposes to 5-aminophathalic acid
As the exited state, 5-aminophathalic acid relaxes to ground state
Excess energy is emitted as blue light
Alkaline luminol, H2O2 solution is used on detecting NO2
The presence o
The luminol is activated with an oxidant. Hydrogen peroxide solution and sodium hydroxide is
used as the activator. In the presence of an catalyst, the hydrogen peroxide is decomposed to form
oxygen and water. The iron in potassium ferricyanide is a catalyst for the reaction.
When luminol reacts with the sodium hydroxide, a dianion is formed. The oxygen produced from
the hydrogen peroxi
