2-1-1. Principle
“Developed a theoretical model to evaluate the overall heat transfer coefficient, considering both conduction through the solid and heat exchange from the solid surface to the gas.”
An accurate determination of the geometrical parameters of the foam was considering the difference in the pore size and the measured value res
fatal damage in some aspects as physical, financial, and time. We have called failure.
Let take attention about that how many causes about metal failure and suggestion about them. And we will show the several examples of bolt failures that have been involved in a certain environment. Through this article we can know how to use a bolt in appropriate situation and make a more sustainable bolt.

■ Design process of Phytoremediation
Area X Depth = Volume of soil
Volume X Density = Mass of soil
3. Soil’s mass X Heavy metal’s concentration
= Total amount of heavy metal calculate
4. ③ - concern standard = Disposal amount
5. Plant’s biomass and distribution ratio
▷ Disposal amount calculate for 3years
6. ④ ÷⑤ = Design period
Partial substitution of Ba by a smaller M2+ ion
unit cell volume decreases and the phase transition temperature decreases
An insulator at room temperature becomes semiconductive after doping
trivalent donars (e.g. La, Sb, Y) substitute for the Ba2+
pentavalent donars (e.g. Sb, Nb, Ta) substitute for Ti4+.
