A theoretical analysis of the problem under investigation in this paper is made principally for the double—arc gears which are used in practice nowadays. It leads to the conclusion. A pair. of mating double—arc gears, when viewed from front to back, will be in meshion simultaneously at both points, of which one is before and the other is after the pitch point, in spite of errors in center—distance and cutting—depth on condition that the parameters of their basic tooth profile satisfy that △ρ(1)=△ρ(2)=△ρ...

A theoretical analysis of the problem under investigation in this paper is made principally for the double—arc gears which are used in practice nowadays. It leads to the conclusion. A pair. of mating double—arc gears, when viewed from front to back, will be in meshion simultaneously at both points, of which one is before and the other is after the pitch point, in spite of errors in center—distance and cutting—depth on condition that the parameters of their basic tooth profile satisfy that △ρ(1)=△ρ(2)=△ρ and α_(no)~((1))=α_(no)~((2))=α_(no)(See § 3) In paragraph § 4 a formula, which gives quantitative relation between errors and pressure angle,is exactly and simply derivated with the help of a diagram(Fig. 2)consisting of mating profiles in the transverse section. In paragraph § 5 the problem concerning the conservation of axile distance between neighbouring mesh—points is investigated. The last paragraph (§ 6) is a critique on the Reference [3].

本文主要针对目前在生产上实际应用的双元弧齿轮就所研究的问题作了理论分析,并得出下列结论:只要其基准齿形的参数满足条件△ρ~(1)=△ρ~(2)=△ρ、α_(no)~(1)=α_(no)~(2)=α_(no)就足以保证在节点前后同时啮合而不受中心距和切深偏差影响(见§3) 本文还利用端面齿廓啮合图(见图2)精确而简易地导出偏差和啮合角之间的定量关系式(见§4)。在§5中探讨了相邻啮合点间轴向距离的恒定性问题。最后一节(§6)是对文献[3]的评论。

On the basis of a survey of the free choice of seat by the audiance in a gymnasium together with some mathematical analysis, the author suggests that a new criterion with a single index, the visual-quality distance, may be used to characterize the visual-quality of seat in gymnasium. The use of a single index makes it possible to make a direct comparison of visual-quality between different seats in a gymnasium or between different gymnasiums.

在体育馆观众自动入席的调查研究和数学分析的基础上,作者建议采用一个单一的评价指标——视质距来表征体育馆比赛厅观众席位的视觉质量,来代替多项参数指标,这样就有可能在席位之间或体育馆之间进行视觉质量的比较。

The HT-80 drafting system is described in three parts. Part I is the program organization and the method for utilization. Part II introduces the features of software. HT-80 is formed in hierarchical block structure, written by the statement of FORTRAN and the instructions of Assembler and consists of 31 basical, functional subroutines and 72 symbols processing subroutines. HT-80 is not only able used for drafting lines, arcs, circles, curves and the graphics, but can also make the graphics change geometrically,...

The HT-80 drafting system is described in three parts. Part I is the program organization and the method for utilization. Part II introduces the features of software. HT-80 is formed in hierarchical block structure, written by the statement of FORTRAN and the instructions of Assembler and consists of 31 basical, functional subroutines and 72 symbols processing subroutines. HT-80 is not only able used for drafting lines, arcs, circles, curves and the graphics, but can also make the graphics change geometrically, such as offset, rotate, scale, translate etc. The three subroutines of HT-80 are modified, it can be fitted to other computers or plotters; Part Ⅲ introduces some of its algorithms. There is an error compensation in each step for descending the accumulated errors. An arbitrary parabole is described with equal distance parabolical parameter equation. An arbitrary curve is interpolated by piecewise weighted mixed parabolical parameter equation to guarantee the first derivative continuity of the curve at the points given. HT-80 was appraised by the National General Administration of Computer Industry and put into application recently.

本文通过三部分来介绍HT—80绘图系统,第一部分介绍HT—80的程序组织和使 用方法:第二部分介绍HT—80的一些软件特点。HT—80是以国产的已配置了RDOS 操作系统的DJS—130机和CTS—2自动绘图机为基本资源,用FORTRAN与汇编语 言的基本语句和指令混合书写而成。整个系统采用了分层模块结构,其中包括31个基 本与功能子程序和72个字符子程序,以绘制直线、圆弧、曲线以及由其组成的各种图形 为目标,并可对所绘制的图形进行平移、旋转、比例等变换。本系统只要稍加修改就可 适用于其它类型的计算机和绘图机。文中第三部分介绍了HT—80中的一些算法。HT —80在绘图的每一步进行了误差补偿.以减少累积误差,采用等距的抛物线参数方程 来描述一条任意的抛物线;对任意曲线采用了分段加权的混合抛物线参数方程来拟合, 保证了拟合曲线在已知点上的一阶导数连续,并采用外延一点参加运算来决定末端的切 线方向,从而保证了拟合曲线与其它线段(直线或曲线)光滑连接。HT—80绘图系统 已经国家计算机总局组织鉴定通过,现已投入使用。
