Rude classification shannan foothill yingshan area , shui peilin dense , mountain range often green jade , in yingshan entire boundary more than200 , 000 chinese acres cultivated land , some 1 / 4 is the mulberryorchard , the yingshan common people generation plants the mulberry toraise silkworms , silk reeling 织 纺 , thus the silkworm raising isprosperous , the cocoon fiber praises jingchu 大别山南麓的英山地区，水沛林密、山峦常翠，英山全境20多万亩耕地中，有四分之一是桑园，英山百姓世代种桑养蚕，缫丝织纺，因而蚕桑兴盛、茧丝扬名荆楚。
The major achievements obtained in this paper are as follows : 1 . it analyses the essential features of sericulture in detail and points out that it has many unique characters that are different from general agriculture , such as the irreplaceability of silkworm eggs , mulberry trees and cocoons , high special - purpose of reeling industry ' s assets , complete commercial characters of cocoons and so on 本文主要研究成果如下：一、详细分析了蚕业的基本特性，指出蚕业具有不同于一般农业的诸多特点，如蚕种、桑树、蚕茧的不可替代性，缫丝企业的高度资产专用性，蚕茧的完全商品特性等。
This thesis adopts vfp database manage system ( dbms ) , oo ( object oriented ) programming and sas statistic analysis software . starting with the impacting factors on cocoon - cooking technique of filature production , the system analyzes diversified data information , along with the relativity of various parameters used in technical designing . based on those , we scheme out the structure composing and system flow chart of cocoon - cooking problem - consulting , also develop maintainable and practical technological designing subsystem with friendly interface , simple operation and fine security 本课题采用vfp数据库管理系统开发技术和面向对象的编程技术及sasrelease6 . 12统计分析软件，采用关系数据模型，从缫丝生产中煮茧工艺过程的相关影响因素入手，充分分析影响煮茧的各种数据信息，以及在工艺设计中用到的各类参数的相关性，在此基础上设计出煮茧问题咨询子系统的结构组成和系统流程图，进而研制具有良好界面，操作简便，安全性好，实用且可维护的工艺设计子系统，以建立一个完善的煮茧工艺设计专家系统（ cctdes ） 。
