The features of this dissertation are lie in: a The concept of"Influence Distance"was presented to quantitatively express"corner effect", systematicly studied on the influence of all factors on"influence distance". It could provide reference to angle designing from the view of heat treatment; b Deeply studied on the influence of shape factor to carbon concentration field. It could provide reference to gear designing from the view of heat treatment; c New model was set up to describe the two-dimensional concentration field of carbide dispersion carburizing. The shortcomings of"effective diffusion constant method"and"equilibrium constant method"were overcome in this model.

本文的特色在于：①提出了用"尖角影响距离"定量描述"尖角效应"的方法，并系统研究了各种因素对"尖角影响距离"的影响规律，从热处理角度为工件尖角部位的设计提供依据；②首次深入研究了齿轮的各种形状因素对浓度场的影响，从热处理角度为齿轮设计提供依据；③建立了能够更有效地模拟过饱和渗碳浓度场的数学模型，该模型克服了"有效扩散系数法"及"平衡常数法"的不足，与"最小自由能法"可互为补充。

Methane adsorbed on the Mn〓O〓-Na〓WO〓/SiO〓 catalyst can not be found, but it can be adsorbed on outgassed silica at 173K. Such adsorption is formed by interaction of the adsorbed methane with O〓〓 sites and hydroxyls on the surface. The appearance of the band at 2904cm〓 of the V〓 mode (sym. stretch.), which is an infrared forbidden vibration, implies that the Td symmetry of the methane molecule may be distorted somewhat on the surface of silica. The small frequency shift (30cm〓) of OH stretching indicates that only a weak hydrogen-bonding interaction between adsorbed methane and hydroxyls exists in the methane adsorption.

甲烷不能在Mn2O3-Na2WO4/SiO2催化剂上吸附但在l73K的温度条件下可吸附于SiO〓表面上，这种吸附是通过吸附甲烷与表面配位不饱和氧和表面羟基作用而形成的，红外禁阻的V〓振动模式显示出红外活性说明甲烷分子的Td对称性发生畸变，甲烷吸附后羟基位移只有30cm〓，吸附甲烷同表面羟基间的氢键作用很弱。

Over the next five years the wine was matured on yeast lees continuing to build character, complexity and depth.

在接下来的5年内继续成熟，剩余的酵母继续使酒体发展的更饱和更深邃。1997年的气泡设拉子柔和丰满，还可经3年的进一步发展。

Delineation result based on the improved ant clustering indicated that the study area could be partitioned into two irrigation management zones. Soil field capacity, saturation moisture content and permanent wilting point in Zone I were greater than those in Zone II, which indicated that soil in Zone I had stronger drought resistance than that in Zone II under the same climate conditions. Delineation of irrigation management zones could provide references and data support for site-specified irrigation management.

改进的蚁群聚类分区结果表明，研究区可划分成2个灌溉管理分区，I区土壤的田间持水率、饱和含水率和凋萎含水率均较II区大，表明在相同的气候条件下，I区的土壤耐旱能力较II区强，分区结果可以为精准灌溉的分区管理提供参考依据和数据支持。

Results:Osteoblasts has the ability of transmembrane transport of metformin. The transport of metformin could be saturable with time and drug concentration adding;a certain range of temperature and pH can promote the transport of metformin;The transport of metformin was inhibited by cimetidine and phenformin,but promoted by verapamil;Oct1 but no Oct2 was expressed extensively in cell membrane and cytoplasm of osteoblasts;The protein level of Oct1 can be up-regulated by metformin with different drug concentrations and times,but no obvious differentces from each group.

结果：二甲双胍能够在成骨细胞上进行跨膜转运，且随着转运时间和药物浓度的增加而增加，并可达到饱和；一定范围内提高温度和pH值可以促进二甲双胍的转运；西米替丁和苯乙双胍对二甲双胍转运有明显抑制作用，而维拉帕米则对转运有明显的促进作用；Oct1广泛表达在成骨细胞的胞膜及胞浆中，而Oct2无表达；二甲双胍在不同浓度及不同给药时间均能够上调Oct1的表达，但各组间无明显差别。
