| 5. | Firstly , a new interface roughness scattering model is developed using exponential autocovariance functions . the simulation results show that the electron mobility calculated using the exponential model are in good agreement with the experiment data 先推导了一种sic反型层表面粗糙散射的指数模型,研究证明应用此模型能够更精确地研究sicmos沟道载流子的输运规律。 |
| 6. | And four constitutive models are established , which are hyperbolic model , half - logarithm model , exponential model and poisson model . combined with the analysis of the change of effective stress , the iteration formulations of settlement calculation are provided 同时建立了双曲线模型、半对数模型、指数模型及泊松曲线模型四种本构模型,并结合有效应力过程分析给出了实用的沉降过程线的反演迭代公式。 |
| 7. | Based on constructing the exponential model of social informatization , this paper measures the level of social informatization in changzhi city from 2002 to 2005 , points out some problems existing in the development of informatization in changzhi city and advances some countermeasures 在构建社会信息化指数模型的基础上,测算了2002 ? 2005年长治市的社会信息化水平,指出了长治市信息化发展中存在的问题并提出了对策。 |
| 8. | With extension of the stolon , changes of the internode length , branching intensity and ramet length were fit to exponential model . it seemed to " flexibly " adapting to the habitat because the clonal architecture of s . vulgaris had both the traits of " guerilla " and " phalanx " 分株长度、间隔物长度和分枝强度随匍匐茎延伸呈指数模型变化,其克隆构型兼有“游击”型和“密集”型的特点,能比较“灵活”的适应环境。 |
| 9. | And the relationship between the models and type of geological units is derived : gompertz model is suitable for the geological unit with a complex geological setting while exponential model is suitable for the geological unit with a single geological settings and this kind of models can be applied to areas of less complicated geological features 结果表明:两地区累计探明储量与预测探明储量的相关因数均大于0 . 75 ;龚帕兹模型较适用于油气藏类型较多、地质状况较复杂的地质单元,指数模型适用于地质状况比较简单的单元。 |
| 10. | The isotropy analyses indicated : the nitrogen density spatial distribution of 0 ~ 100cm depth displays the interest of moderate spatial correlation , its theory pattern accords with the exponential model . but the nitrogen density spatial distribution of 0 ~ 30cm depth is the very feeble correlation , its theory pattern accords with the spherical model 各向同性空间分析结果表明, 0 100cm土壤层厚度氮密度的空间分布体现为中等的空间相关性,它的理论模型符合指数模型;而0 30cm土壤层氮密度的空间分布则体现为很弱的相关性,它的理论模型符合球状模型。 |
