In this paper, the authors, by means of the method of systematical analysis, have studied the ecological phenomenon of natural thinning of Populus tremula var davidiana. A research on its mechanism of negative feedback has been made, the negative feedback return circuit designed and a mathematical model established. This may provide a new method for studying the natural thinning phenomenon of forests and some important problems concerned have also been brought up for discussion.

本文从山杨林自疏现象这个生态学问题出发,建立了它的数学模型。用系统分析的方法,探讨了它的负反馈机制,做出了负反馈回路图,为研究森林自疏现象提供了一种新的方法,并提出了一些值得进一步探讨的问题。

This.paper,introduces the forecasting method for the count-strength product of yarn under agiven program of cotton mixing by using dynamic mathematical model established by computer.Inorder to reduce the deviation of forecasting results,a method of deviation correction is used,thusreducing the forecast relative standard deviation from 20% to 2.5%.It greatly increases the fore-cast accuracy.So the method introduced here is of practical value.The forecast of the count-strength product of yarn using computer...

本文介绍了利用计算机建立动态数学模型,对某种给定配棉方案下的成纱质量进行预测的方法。为了减小预测偏差,采用了偏差校正的方法,使预测的相对标准差由20%减小到2.5%,大大提高了预测精度,因而具有实用价值。利用计算机对成纱质量进行预测,作为计算机配棉管理系统的一个组成部分,已在北京第一棉纺织厂运行两年了。

The effects of some non-linear factors such as the non-linear stiffness of the machine tool structure, the working relief limit, the non-linear characteristics of the cutting force and the locus of edge partly deviating from the workpiece on machine chattering are investigated and mathematical models established. Experimental results as well as assessments on some previous works are given.It is pointed out that the investigators in the field of non-linear chattering research on machine tools are now confronted...

The effects of some non-linear factors such as the non-linear stiffness of the machine tool structure, the working relief limit, the non-linear characteristics of the cutting force and the locus of edge partly deviating from the workpiece on machine chattering are investigated and mathematical models established. Experimental results as well as assessments on some previous works are given.It is pointed out that the investigators in the field of non-linear chattering research on machine tools are now confronted with the difficulty that the electromagnetic excitation technique successfully used in the linear chattering theory cannot be applied to the non-linear feature of the machine tool structure at all. A possible way out is suggested.

本文研究了机床结构中的非线性刚度、切削过程中的后角限制、刀刃轨迹部分地越出工件材料和非线性切削力等几种非线性因素对于机床颤振过程的影响,及其相应的数学模型;同时评述了某些研究者过去所进行的工作及其结论.本文还分析了机床的非线性颤振理论的研究中所面临的一个重大困难——现今在线性理论的研究中用得十分成熟的一套电磁激振技术,根本无法揭示机床结构的非线性特征,并指出了解决这一困难的可能途径.
