This paper discusses whether the horizontal projection and profile projection will be a circle when a plane cuts off a circular cone at an oblique angle with an ellipse section line. It is determined that the direction of both the major and minor axis of ellipse’s horizontal projection will keep constant. In addition the paper provides with the conditions which the section plane meets when its profile projection is a circle.

In this paper,are first analyzed the fibre-size and the related evenness parameter along with the involved errors in describing raw silk fineness of silk industry. Then among many apparatus used to detect the two above-mentioned parameters,are discussed the Uster evenness tester,the model SD-1 size tester,and the model Y1051 electrostatic excitation type fibre fineness meter. It is found that the traditional size parameter is,not exactly to scale, the raw silk fineness and has relative error up to 43.80% in...

In this paper,are first analyzed the fibre-size and the related evenness parameter along with the involved errors in describing raw silk fineness of silk industry. Then among many apparatus used to detect the two above-mentioned parameters,are discussed the Uster evenness tester,the model SD-1 size tester,and the model Y1051 electrostatic excitation type fibre fineness meter. It is found that the traditional size parameter is,not exactly to scale, the raw silk fineness and has relative error up to 43.80% in reflecting to the section area. Investigating the sections of raw silk reveals most of them to be elliptical,so that the area of raw silk ellipse section detected in bi-directions is put forward as the parameter to describe raw silk fineness. Moreover, the corresponding error is analyzed through mathematics operation with the ellipse model.
