In addition, high-resolution time-of-flight secondary ion mass spectrometry was used to study the chemical composition of various pyrite forms in the No.9 coal seam (St,d = 3.46%) from the Wuda Coalfield. These include bacteriogenic, framboidal, massive, cell-filling, fracture-filling, and nodular pyrites.

The carbon foam were prepared by self-bubbling at high pressure from AR pitch added sodium dodecyl benzene sulfonate and Span-40, respectively. The bulk density, pore rate, compressive strength, thermal conductivity at room temperature and crystallitic parameters of carbon foam were measured. The rheological properties of AR pitch and pore structure of carbon foam were investigated.

The coarse grain in cast strip is produced on the condition that cool speed is not fast enough to overcool aluminum melt in whole cast area, and only provide proper temprature gradiant to keep cellular grain growing up.

铸轧区内铝液与铸轧辊接触瞬间，当铸轧辊冷却强度不足以使整个断面铝液同时产生较大的过冷，而仅能保持胞状晶生长所需的液体温度梯度时，铸轧板就会出现粗大晶粒；根据传热学原理，分析了具体生产条件，提出增大铸轧辊冷却强度、降低前箱温度以及添加铝钛硼丝等防止铸轧板产生粗大晶粒的措施。

The study showed that the biosorption process could be described well by pseudo-second-order kinetic model and Freundlich isotherm model.Higher cell concentration was favorable to the biosorption.Temperature's effect on the biosorption was not obvious.The oxygenous and nitrogenous functional groups on the cell wall played a very important role in the process of biosorption.Microdeposits were formed by int...

结果表明，菌体对银的吸附量可达91.75 mg/g，吸附过程符合Pseudo-second Order吸附动力学模型，相关系数高达0.999 9；吸附热力学很好地符合Freundlich吸附等温模型，相关系数为0.99；考察菌体浓度和温度对吸附的影响发现，菌体浓度增加有利于对银离子的吸附，温度对吸附影响较小；FTIR、SEM及EDAX实验结果表明吸附存在2种吸附机理，一为菌体表面一些含氮氧的基团对Ag+的络合作用，二为菌体分泌的胞外多糖等物质对Ag+的微沉淀成晶作用。

The coatings, which had gradient structure of porously outer layer and densely inner layer, were mainly composed of rutile and anatase, and the elements of calcium and phosphorus existed in the form of perovskite, calcium phosphate and amorphous phosphates.

It means AIMD is a reliable method to simulate liquid and amorphous systems. All the supercells employed in our paper contain more than 100 particles and the simulation time is about several picoseconds.

结果显示，我们的模拟虽然仅仅选取64（和100）个原子的立方超元胞和20皮秒的模拟时间，但是得到的数据与实验结果极为吻合，说明从头算分子动力学方法模拟非晶态合金是可靠的。

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

另一方面，更重要的是由于城市住房是一种异质性产品。

Climate histogram is the fall that collects place measure calm value, cent serves as cross axle for a few equal interval, the area that the frequency that the value appears according to place is accumulated and becomes will be determined inside each interval, discharge the graph that rise with post, also be called histogram.
