The low voltage breaker is composed of electric conducted system,extinguish-arc room, heat tripper and electric magnetism wink-moved mechanism.The functions of move mechanism directly impact the reliability of breaker's move. This topic is imported by using the exchange module of multibody dynamics simulation software automatic dynamic analysis of mechanical system,and then its movement was simulated by applying ADAMS,with the design and the optimization of DW16 Low-voltage breaker's ususal mechanical movement.

Canadian ice wine is made from the hundreds of years old German grapes through a very delicate method whose intricacy vindicates its high value. When it comes to harvest season, the viniculture farmers would leave the grapes exposed to snow and frost rather than picking them down the baskets till the next year when the temperature is below 15℃ and all the grape juice is solidified to clot, then they pick the grapes manually in a paced manner. The grapes picked in this way are very sweet. The percentage of sugar is increased to 45% in the 600 liters grape juice extracted from the 1000 liters grapes. With the 600 liters juice, only about 150 liters ice wine can be made.

Using the one-atom theory, the electronic structures of Pt-electrocatalyst with fcc structure was determined as follows:(5dn)6.48 (5dc)2.02 (6sc)1.48(6sf)0.02. Compared to the result obtained by the first-principle method such as FP-LMTO, CASTEP, their results are in good agreement with each other. Comparing the calculations of physical properties such as lattice constants, cohesive energy and bulk modulus by OA method and first-principle method, the result obtained by OA method is in excellent agreement with experimental value, but the result obtained by first-principle method is not accordable. The relationship between the electronic structures and catalytic performance was explained qualitatively by OA method and first principle method according to its electronic structures. Because the d-orbital vacancies increases and static density is high around Fermi energy band, Pt has good catalytic performance.
