Although the measuring technique of rotational error of spindles attracts more and more attention recently there are still some problems in the basic theory and concepts which need to be studied and unified. In this paper some views are presented on the definitions which deal with the rotating axis of spindles, the average rotating axis of spindles, the generalized or limited rotational error motion of spindles and on the fundamental component of signals. To keep the consistancy of the theory with the measuring technigue, the author doubts if "the instantaneous centers theory" of rotating axes is correct and agrees with the opinion that rotating axes are represented by using "the theory of revolution around the point which moves translationally." We are in the opinion that the ide(?)tifying and processing of fundamental in signals must be related to the definition of rotating axes. In addition, the paper presents the conditions under which the Least Square Center and Radius may be obtained by mean value calculation and also gives the mathematical proof of validity of this method. The paper also studies several approximate Algorithm that may be applied under general conditions.

近年来,虽然主轴回转误差运动在测试技术方面得到了日益广泛的重视,但是在基本概念、基本理论的研究方面仍然有着一些尚待探讨和统一的问题。本文仅就其中关于主轴的回转轴线、主轴的平均回转轴线、广义或狭义的主轴回转误差运动及一次谐波的研究中存在的问题,提出几点看法。本文从描述主轴回转误差运动的理论与工程中的测试技术的一致性出发,对回转轴线的“瞬心说”提出质疑,赞成以“绕平动定点转动说”来描述回转轴线,还进一步说明了对信号中一次谐波的认识和处理原则,是与回转轴线的定义相联系的.本文给出了以均值计算求最小二乘圆心和半径的条件和证明,并研究了在一般条件下的几种近似算法.

This test determined the fibre length and width/width of fibre cell walls/cell diameters of popular wood of nine introduced species of populus X euramericana(Dode)Ginier cv.“Eugenei”etc.in great qu- antities.As a result,ratio between fibre length and width/that betw- een cell walls and cell diameters/distribution and frequency of fibre length and width were calculated from the above four mean values. In addition,the quantities of tissue ratio of wood moleculars of indi- vidual tree species were determined. Based on the results of actual determination and statistical calcul- ation,the comparison and analysis were made of making paper-pulp for paper-making from wood fibres of nine kinds of popular trees.The results from analysis indicated that the fibre length of nine kinds of popular trees,except the shortest fibre length of Populus nigra Var. thevestina X P.hopeiensis +P.Simonii,are allthe medium length with- out obvious differences in fibre width,being 20.68 Micron witch the maxi- mum difference being 5.03 Micron.The distribution and frequency of fibrelength and width showed that the maximum distribution coincided with the maximum frequency. Based on the ratio between length and width calculated from wood fibre,the paper indicated that the ratio between length and width of nine kinds of popular trees was 40.29-52.70,which was greaser that the ratio of 35-45 required in making paper pulp process for paper- making,but the ratio of 35-45 was required to ensure better weaving of fibres.The ratio between thickness of fibre cell walls and cell diameters (2w/l)is smaller that 1,belonging to the first class of R.O.H.Ruaker. The fibre contents of wood of various popular tree species were between 68.6 percent to 73.7 percent,being far greater than 50 percent. In a comprehensive survey of wood fibre morphological values of nine kinds of popular tree species,although they meet the needs of making paper pulp for paper-making,the autors hold that the six kinds of popular trees such as Populus X euramericana(Dode)Guin- ier cv.“Eugenei”/Populus X euramericana(Dode)Guinier cv.“Robusta”/ Populus X euramericana(Dode)Guinier ev.“Graupaer-Selktion No.158.” /Populus X euramericana(Docle)Guinier/Populu“sepera”/Populus X eur- americana(Dode)Guinier cv.“Sarce Rouge”are more suitable popular tree species to be used in making paper pulp for paper-making in tak- ing into comprehensive consideration of their fast growth and wood qualities in combination.

本项试验对尤金杨等九种引种杨树木材的纤维长度、宽度、纤维细胞壁厚度及胞腔直径进行了足够数量的测定,并由此四项均值计算出纤维的长宽比、壁厚腔径比,以及纤维长度、宽度的分布和频率。此外还测量了各树种木材分子的组织比量。根据实测结果和统计计算,就九种杨树木材纤维对制浆造纸的适宜性作了对比和分析。分析结果认为九种杨树的纤维长度,除箭河小杨属短级外,其余皆为中级长度。而纤维宽度差异并不显著,平均在20.68~25.71微米之间,最大差异仅为5.03微米。纤维长度、宽度的分布和频率,显示其最大分布和最大频率基本一致。文章根据各树种木材纤维的长度和宽度计算出的长宽比表明,九种杨树的长宽比为40.29~52.70,皆大于制浆造纸生产过程中为保证纤维能良好地交织在一起所要求的35~45比值。纤维细胞壁厚腔径比(2w/1)亦皆小于1,属朗克尔第一级。各树种木材的纤维含量在68.6%~73.7%之间,远远大于50%。纵观九种杨树木材纤维形态值,虽均合乎制浆造纸要求,然结合其生长速度、木材性质综合考虑,作者认为尤金杨、健杨、德国158号杨、欧美杨、合作杨及撒尔红杨等六种杨树,更适宜于作为制浆造纸原料的树种。

This paper presents a summary of the simulated and On- the -spot experiments in inserting forces of a rectangular shovel working into granular or lumpy materials, from which a conclusion was statistically reached of the mechanism of the operation.

论文是几年来模型实验与实物实验结果的总结。提出了楔形体插入块状散体的统计机理,它不同于大家所熟知的楔形体插入细粒物料的机理。论文还以离散介质为出发点,用统计方法,获得了插入阻力的统计分布规律和分布参数的变化规律,并建议用具有可信度的插入阻力计算公式取代传统的均值计算公式。最后还提供了我们的实验结果和通用的国外公式的比较结果,说明我们的结果较符合实际。
