依据硬盘驱动系统中读写头与盘面的构造,结合现有的楔型和阶跃型气体滑动轴承的特点,提出了一种气体滑动轴承结构,并采用直接模拟Monte Carlo(DSMC)法数值研究了滑动轴承的最小间距、移动速度和系统温度对轴承承载能力的影响.计算结果表明,所设计轴承的承载能力随移动速度的增大而增加,随最小间距的增加和系统温度的升高而减小;轴承的承载能力对轴承最小间距的变化更敏感.

Objective: To observe the concentration of se-rum homocysteine in intellectuals and the re-lated influential factors. Methods: The concen-trations serum homocysteine and saliva cortisol were measured in 138 intellectuals from three cities, Tianjin, Guangzhou and Chengdu in China. All the subjects had senior titles of tech-nical post, aged 40-69 years. Results: The mean value of serum homocysteine concentration in intellectuals was 20.6±0.8μmol/L, higher than the reference value. With the increase of cortisol levels the homocysteine concentrations rise (P <0.05). The mean value of homocysteine con-centration was highest in 40-49 years old group. Men had higher homocysteine level than women in this investigation. According to the mean value of homocysteine concentration among different cities, Tianjin was highest, Chengdu medium, Guangzhou lowest. Conclusion: The serum homocysteine concentration of intellec-tuals is higher than the reference value. The stress level, gender and resident cities might contribute to the differences in serum homo-cysteine concentration in Chinese intellectuals.

Climate change resulted in changes in crop growth duration and planting structure, northward movement of planting region, and more severe plant diseases and insect pests in Northwest China. It caused earlier seeding for spring crop, later seeding for autumn crop, accelerated crop growth, and reduced mortality for winter crop. To adapt to climate change, measures such as optimization of agricultural arrangement, adjustment of planting structure, expansion of thermophilic crops, and development of water-saving grassland and livestock were enhanced. agriculture have been taken. Damaging The deterioration trend of grassland was consequences of imbalance between intensified; both grass quantity and quality declined. With overgrazing, proportions of inferior grass, weeds and poisonous weeds increased in plateau pastoral areas. Returning farmland to grazing, returning grazing to grassland, fence enclosure and artificial grassland construction have been implemented to restore the grassland vegetation, to increase the grassland coverage, to reasonably control the livestock carrying capacity, to prevent overgrazing, to keep balance between grassland and livestock, and to develop the ecological animal husbandry. In Northwest China, because the amount of regional water resources had an overall decreasing trend, there was a continuous expansion in the regional land desertification, and soil erosion was very serious. A series of measures, such as development of artificial precipitation （snow）, water resources control, regional water diversion, water storage project and so on, were used effectively to respond to water deficit. It had played a certain role in controlling soil erosion by natural forest protection and returning farmland to forest and grassland. In the early 21st century, noticeable achievements had been made in prevention and control of desertification in Northwest China. The regional ecological environment has been improved obviously, and the desertification trend h

采用密度泛函(DFT)B3P86方法,结合Dunning的相关一致三重基cc-pVTZ,优化计算硼氢化物(B2Hn)(n=1～6)可能的几何构型,得出最稳定结构的几何参数、电子结构和振动频率等参数,给出了最稳定结构的总能量(ET)、结合能(EBT)、平均结合能(Eav)、电离势(EIP)、能隙(Eg)、费米能级(EF)和氢原子差分吸附能(Ediff)等。结果表明,硼氢化物基态稳定结构的电子态分别为:n为奇数时为双重态2 A,n为偶数时为单重态1 A。由于B原子属于缺电子原子,能与等电子原子H化合,通过桥键形成多中心键的氢化物,优化计算发现,硼氢化物最稳定结构都存在桥键,且n为奇数的桥键作用比相邻偶数的强。通过分析最稳定结构的电子特性发现,B2Hn(n=1～6)中B2H6的电离势和能隙最大,桥键比端键长,红外光谱强度最大,说明该硼氢化物最稳定,且其氢原子差分吸附能最大,储氢性能相对最好。
