This article studies the Microsoft Game-Freecell. It applies the Pigeonhole Principle, Ramsey Principle, Bipartite Graphs Principle to approve the maximum available space to complete the game successfully under random sorting. It introduces the specific algorithms that can archive the goal successfully under the game rules. It also presents the calculation of permutation under this algorithm by adopting the Mobius Inversion and Inclusion-Exclusion principle.

In this paper,a series of parameters as aperture、surface-area ratio to particle mass、hole-volume of pyrite (FeS2) particle,and the release characteristic of sulfur before reaction and under different temperature of drop-tube furnace were measured using ASAP2000 instrument from Micromeritics Co. USA with isothermal-absorption method. The configuration of FeS2 and its reaction products were summarized from the experiments.

采用美国Micromeritics公司的ASAP2000型比表面孔容测定仪,用等温吸附法,对硫铁矿(FeS2)在反应前及一维沉降管炉不同炉温条件下的孔径、比表面积和孔容积等参数的变化特性及硫的释出规律进行了测定,得到了对FeS2及其反应产物形态的一定认识。

To King Zhou of China's history of well-known tyrant, pet beauty Da oneself and others, will allow operators, dry, micro-son箕子such as the abolition of denigrating each贤臣will be completely handed over to the Chief and other charges Mr Rigoletto .~~~~~~

商纣王是中国历史上有名的暴君,宠爱美女妲己,将商容、比干、微子、箕子等贤臣逐一废除贬斥,将政务完全交给费仲等弄臣。~~~~~~

Pseudo-boehmite was prepared with nitric acid and sodium aluminate under the same precipitation conditions but different ageing and washing conditions. The influences of ageing temperature, ageing time and ageing media were studied. It was shown that pronging the ageing time and increasing temperature lead to improve crystallinity of PB., the pore diameter of PB can be increased after NH4HCO3 is added in the ageing medium.

在相同成胶条件下利用铝酸钠溶液和硝酸制备拟薄水铝石,而在不同条件下进行老化,研究了老化温度、老化时间及老化介质的影响,结果表明延长老化时间、提高老化温度和老化pH值有助于结晶度的提高,使用NH4HCO3等具有扩孔作用的溶液作为老化介质会降低产品的堆密度和增加孔径、孔容、比表面积。

This model optimizes the 110 kV-substation number, its capacity and unit number, using the minimum cost of network construction and grid energyloss as object function, the capacity-load ratio of transformer and the radius of power supply as constraint condition. DIPSO is used to find out the best result of this model.
