Effect of the elastic factor on the hydrodynamic stability of a structurally viscous medium


Elastic factor supplies at the aggregate level also imply that demand, as well as supply factors, play a role in longrun growth.


The third set of stylized facts stresses the role that elastic factor supplies for dynamic activities play in the development process.




 The paper presents a model of twolevel inventory system constituted a vendor and several retailers. In the model, the vendor and the retailers' short supply is permitted in a certain service level and their revenue satisfies Paretoaffection. Finally, it gives an illustration and analyzes the affection of the price elasticity to the system.  研究一个供应商、多个销售商组成的两级供应链库存系统,针对具有价格弹性的市场需求、含有价格折扣、允许供应商和销售商产生缺货以及满足供应商和销售商Pareto有效性的情况,建立了使供应链系统整体盈利最大的存贮模型。并结合算例分析了价格弹性因子对系统盈利水平的影响。  Objective To compare time, velocity, accelerate and decelerate indexes of common carotid artery (CCA) walls pulsate for evaluating CCA elasticity in healthy adult. Methods Blood pressure and RCCA were studied (by ultrasound with simultaneous ECG monitoring) in 105 healthy adults. The curve of CCA walls pulsate was recorded by the technology of tissue Doppler imaging. MedArchive Viewer software was used to measure time, velocity, acceleration and deceleration.

Objective To compare time, velocity, accelerate and decelerate indexes of common carotid artery (CCA) walls pulsate for evaluating CCA elasticity in healthy adult. Methods Blood pressure and RCCA were studied (by ultrasound with simultaneous ECG monitoring) in 105 healthy adults. The curve of CCA walls pulsate was recorded by the technology of tissue Doppler imaging. MedArchive Viewer software was used to measure time, velocity, acceleration and deceleration. The correlation indicators of CCA elasticity was calculated. Factor analysis can be used to combine the correlation indicators of CCA elasticity to elastic factor. Elastic factor and indexes of CCA walls pulsate were disposed by Bivarite Correlations Analyze and Linear Regression Analyze. Results The correlation coefficients between time factor (T), velocity factor (V), accelerate factor (A), decelerate factor (D) and elastic factor were 0.132, 0.680, 0.735, 0.485, respectively. The regression equation: Y=0.757V+0.401A0.459D. Conclusion Velocity index, accelerate index and decelerate index of CCA walls pulsate all can be used for evaluating CCA elasticity of healthy adult. The velocity index was the closest index related with elasticity and was the best representation in all indexes of CCA walls pulsate. The rapider velocity of CCA walls pulsate was, the better elasticity was. The relations between accelerate index, decelerate index and elasticity were in the next place. There was no relation between time index and elasticity.  目的 比较壁运动时间指标、速度指标及加、减速度指标对健康成人颈总动脉(CCA)弹性的评价作用。方法 测量105例健康成人血压,连接心电图,行右CCA超声检查。采用组织多普勒技术记录CCA壁运动曲线,应用MedAr chive Viewer软件进行CCA壁运动的加速度前时间、加速度时间、减速度时间、峰值速度、加速度及减速度的测定,计算获得弹性参数。通过因子分析将诸项弹性参数合并生成弹性因子。将弹性因子与壁运动诸项指标进行简单直线相关分析及多元线性回归分析。结果 时间因子(T)、速度因子(V)、加速度因子(A)、减速度因子(D)与弹性因子的相关系数r分别为0.132、0.680、0.735、0.485。V、A、D 的回归系数分别为0. 757、0. 401、 0. 459,回归方程为: Y= 0. 757V+ 0. 401A0.459D。结论 壁运动中速度指标、加速度指标与减速度指标均可用来评价CCA弹性。其中速度指标和弹性关系最密切,最能代表弹性,壁运动速度越快弹性越好。加速度指标与减速度指标和弹性关系其次。而时间指标与弹性无关。  The means of the main factors were explained, the relationship between main factors and woolen sweater style and the method by which the main factors were determined by calculation of square difference and its contribution were introduced in this paper.

The means of the main factors were explained, the relationship between main factors and woolen sweater style and the method by which the main factors were determined by calculation of square difference and its contribution were introduced in this paper. By analyzing and studying to the main factors, it is obtained that the basic styles of woolen sweater have five kinds. These styles can be expressed by five basic main factors, they are distortion factor, elastic factor, bulkness factor, rughtness factor and sorftness factor. They are almost no relations among these main factors, which lay the foundation for the studying of objective synthetic evaluation to woolen sweater.  介绍了主因子分析法中主因子的含义、主因子与毛针织服装风格之间的关系以及通过计算每个因子的方差和累加方差贡献率的大小确定主因子的依据和方法。通过对主因子的分析研究,得出了毛针织服装的基本风格可归纳为5种,用5个基本因子,即变形因子、弹性因子、膨松因子、粗糙因子和刚柔因子来表示。这些因子之间的相关性很小,这是主观评价所不能达到的。这些主因子的确定,为毛针织服装风格客观综合评价的研究奠定了基础。   << 更多相关文摘
