     The attention paid to acknowledgement in the academic papers in sci-tech periodicals at home is very different from that abroad. Through analyzing 16 437 academic papers in 40 Chinese and foreign sci-tech periodicals,it comes to a conclusion: the number of papers with acknowledgement in foreign sci-tech periodicals can be above 50%,and that in Chinese periodicals is only 2%-3%.
     国内外科技期刊对文后“致谢”的重视程度差异很大,统计表明,国内外40种科技期刊中的16 437篇论文,其文后有致谢内容的比例,国外超过50%,而国内仅为2%~3%。

     It was also found out that this relationship between structural variables and system functions was still placed in the blank. Based on this,the paper has applied three structural covariances and discussed the impact of structural variables on the network risk.
     基于此,本文引用了复杂网络理论中刻画网络结构的三大统计结构变量:度分布、聚集系数以及平均最短路径长度作为刻画集群网络结构的变量,在此基础上初步探讨了这些结构变量对集群网络风险的影响。

     This difference can be utilized for the detection of edges of angiographic images. We propose a maximum statistical relativity (MSR) algorithm that is a kind of matching filter. As a result, the edge detection algorithm is not sensitive to noise and low level textures of images.
     由于图象边缘区域与非边缘区域的局部直方图明显不同 ,因而可以利用这种差别来检测图象的边缘 ,同时还基于局部直方图构造了一种匹配滤波器算法——最大统计相关算法 ,该方法不敏感于图象的噪声和低电平纹理 ,而且能够有效地从噪声和纹理中分离提取造影图象的微弱边缘 .

本文继续文献[1],总共积累了493个非弹性作用事例。在ω=1.5GeV附近的峯仍然明显地突出于单π交换近似理论曲线以外,物理解释同文献[1]。镜象系质子非弹性系数Kz值的实验分布也在丰度较大的统计基础上与上述单π交换理论作了比较。利用鉴定了的π介子在实验室系的动量谱对未鉴定的粒子中应有的质子数作了估计。

In this paper, 5R-C mechanism is taken as an example to carry out the error analysis and synthesis of spatial six-link mechanisms and to use multi-criteria optimum synthesis for considering mechanical errors and manufacturing costs. In order to save computation time, various identity conditions of geometrical closure are used to derive a certain number of necessary-equations which contain less unwanted motion variables. As a result, sets of linear equations are obtained to solve for partial derivatives necessary...

In this paper, 5R-C mechanism is taken as an example to carry out the error analysis and synthesis of spatial six-link mechanisms and to use multi-criteria optimum synthesis for considering mechanical errors and manufacturing costs. In order to save computation time, various identity conditions of geometrical closure are used to derive a certain number of necessary-equations which contain less unwanted motion variables. As a result, sets of linear equations are obtained to solve for partial derivatives necessary to the error analysis of spatial multi-link mechanisms. Clearance vectors at real kinematic pairs may be simply converted into extra errors of structural parameters with satisfactory approximation. Further more, by the stochastic model set up in the paper, clearance vectors are also analysed satisfactorily to obtain statistical amounts having practical effects. On the basis of error analysis, the general applicable multi-criteria optimum programs for cousidering manufacturing tolerances and clearances of spatial mechanisms have been developed.

本文主要以5R—C机构(R表示转动副,C表示圆柱副)为例,进行了空间六杆机构的误差分析与多目标优化综合。为便于上机计算,对于多杆空间机构误差分析中所用的偏导数,文中利用机构封闭性的各种等同条件,通过含有较少中间运动变量的线性方程组求得。对于各种常见运动副中的间隙误差矢量采取了折算为有关结构参数的附加量的方法,通过所建立的随机模型进行了统计分析以得到实际影响大的统计量。在误差分析的基础上,本文进一步对空间连杆机构提出了通用性较强并且考虑公差和间隙的多目标优化程序。

In this paper, starting from transport theory, estimated functions of Monte carlo direct analogue and statistical estimation have been obtained by means of term wise integration. We deal with variations of transmissivity and reflectivity in optical thickness T, albedo of a single partical a, and anisotropy g when plane wave passes through a layer discrete random media. The results of statistical estimation method are in good agreement with those given in reference [2]. As a result of considerable statistical...

In this paper, starting from transport theory, estimated functions of Monte carlo direct analogue and statistical estimation have been obtained by means of term wise integration. We deal with variations of transmissivity and reflectivity in optical thickness T, albedo of a single partical a, and anisotropy g when plane wave passes through a layer discrete random media. The results of statistical estimation method are in good agreement with those given in reference [2]. As a result of considerable statistical fluctuation of scattering point samples in direct analogue method, the deviation of calculation would be larger as the optical thickness increases or anisotropic scattering or absorption becomes stronger.

本文从输运理论出发,利用逐项积分法获得直接模拟法和统计估计法的估计函数。研究了平面波通过平面离散随机介质的透射光强和反射光强随光学厚度、反照率、不对称因子的变化。统计估计法获得与文献[2]给出数据完全一致的结果。在直接模拟法中由于粒子空间位置抽样产生较大的统计涨落,当光学厚度增大,散射的各向异性增强及强吸收时其结果的偏差增大。
