Abstract:Presented in this paper are the research results on dry Factionation of fat or oil with the addition of seed crystals. To fractionate fat or oil to remove the (factions with high melting points, this paper describes a method, in which, a portion of the cr

Abstract:Five flavonoids were isolated from the dried leaves of lonicera japonica thunb in Ling-Yi Shang-Tong province. They were loniceraflavone, lonceraflavone-6-rhamnoglucoside, luteolin, lonicerin (luteolin-7-rhamnoglucoside), and luteolin-3'-galactoside. Thei

Abstract:Headspace vapours above the silk worm chrysalid oil were collected, using porapak-Q as absorbents to trap the off flavour. Desorption was carried out in an specially designed electrical heating apparatus. Liquid nitrogen was used as freezing agent. Off fl

Abstract:The interracial film thickness of after wax emulsion 82-123 emulsified by mixed non-ionic surfactant was studied by using electronmicroscope method, Viscosity method, shell method and surface tension method. The results obtaincd from the four different me

Abstract:This article analyzes the motion regularity of sieve shaker, calculates its displacement, velocity and acceleration, and makes analysis of the force bearing of the grain on the surface of sieve, which can be available for reference of designers, manufactu

Abstract:本文介绍普通无心磨床提高磨削精度的方法。对改进结构设计、改善静、动态成圆机理的条件进行了分析、试验,取得了较好的效果。一般情况下圆度可小于1微米,最高速0.3微米

Abstract:According to the equality or inequality of the permissible angles for rise and return, object function and constraints of optimum design of disk cam mechanism with swinging roller follower are proposed respectively in this paper. Such mathematical models

Abstract:In this paper, the mapping formulas and address table as well as graphic block design and display for APPLE computer are presented. The bit mapping technique is the foundation for fast graphics display with the Assembly language. Compared with high level

Abstract:The structure and performance of model WKZX microprocessor automatic control system are described in this paper. The new design concept and principles for the microprocessor based on digital automatic control system are also given. Also presented(in this

Abstract:According to the deformation and beading of weft and warp in the process of forming fabric, this article introduces the concept of the change of internal force which exists in the prccess. And we can explain the theory of geometric structure and a lot of
