查询词典 calculus of finite difference

We haveour own intelligent property rights. Among them our spotlight is one of our typical products. It's the first time that the image illumination technology is used on the spotlight in the world. The reachable distance is raised 2-3 times, its beam of light angle is raised 5-6 times, and much power and energyis saved and illumination well-distributed. There is little color difference, comet difference and color difference for a point. Our spotlight can represent the latest technology of the same products in contemporary age and is granted national invention patent and national new practical patent.

objective to study the relationships between smoking,atherosclerosis and c-reactive protein.methods to detect the serum crp and serum lipid while in quiring the smoking status for278patients with cardio-vascular disease.then analyed the crp level among different groups.results crp level had significant difference between smoking and non-smoking groups,atherosclerosis and non-atherosclerosis groups;but it seems no relationˉship with high lipid.in differentsmoking amount groups,crp level had significant difference in atherosclerosis paˉtients,but no significant difference in non-atherosclerosis patients.conclusion smoking,high lipid and crp were all very good prognostic mark in atherogenesis.crp was a significant prognostic mark in atherosclerosis influenced by smoking.

目的 初步探讨c反应蛋白crp与吸烟和动脉粥样硬化三者之间的关系。方法通过对临床278例动脉粥样硬化和非动脉粥样硬化病人血清crp和血脂的检测及吸烟情况的调查，应用spss统计软件进行差异分析，比较不同组间crp水平。结果 crp在吸烟与不吸烟组、动脉粥样硬化和非动脉粥样硬化组差异有显著性。而在血脂正常组和高血脂组差异无显著性。在不同吸烟量组间：非动脉粥样硬化组间crp水平差异无显著性，而动脉粥样硬化组差异有极显著性。结论吸烟、血脂升高、crp升高是动脉粥样硬化较好的预示指标；在吸烟人群中crp升高者更易患动脉粥样硬化。

The results were as follows. In the insert mutation genotypes, there was significant difference between body weights of 2 weeks aged BB and AB genotype (P.05), while there was no significant difference between AA and other genotypes.

Suppose G is a finite group, then QG is a semisimple Q-algera, obviously ZG is a Z-order of QG,we denote the maximal Z-order by ?.If G is not abelian, it is not an easy thing to determine г; if G is an abelian group, then QG is isomorphic to the direct sum of a finite number of number fields, and r is the direct sum of these rings of algebraic integers of those number fields, but which elements of QG belong to r is not clear.

设G是一个有限群，那么QG是一个半单代数，ZG是QG的一个Z-序，设Γ是QG的一个极大Z-序，当G是一个非交换群时，Γ的求解是困难的问题；当G是一个交换群时，QG同构于有限多个数域的直和，Γ相应的就是各数域代数整数环的直和，但Γ具体是QG中那些元素不清楚。

Aiming at the currently shortage of XML streams quality detecting, this paper proposes a new forecasting method of XML streams quality by least squares support vector machines, which is used the method of XML keys' vector matrix as windows, and vector product wavelet transform to multilevel decompose and refactor the XML streams series, that can fulfill real-time checking demand of XML quality, and ensure constraint, consist- ency and integrality. For even more adapting net load, it proposes a control strategy by weight and adaptive adjustment to ensure XML streams quality.
