Factor analysis is a very popular multivariate statistical analysis method. It can summarize some unobservable factors from the test results which can summarize most of the observed data. The factor analysis suggest the DP, furfuran and CO_X can be divided into insulation aging factor, while the hydrocarbon gas and hydrogen were divided into another group which can be called insulation fault factor. The result of the factor analysis

因子分析作为一种常用的多元统计分析方法，可从众多可观测变量中，概括和推论出少数不可观测的潜变量，用最少的因子去概括和解释大量的观测事实；本文将试验过程中90℃下油中溶解气体、绝缘聚合度、糠醛等参量进行因子分析，结果表明：绝缘聚合度、糠醛、CO_x被分为一类，代表绝缘老化因子：烃类、氢气、被分为一类，代表绝缘故障因子；因子分析结果与现场经验一致，相互印证，具有重要意义。

Differ with answer fruit, hip and aggregate achene achene are become by a beautiful ovarian development, in this kind of floral the flower often has from unripe carpel gynoecium, every gynoecium becomes a relatively independent fructification from development each, form the aggregate achene achene that gathers on a thalamus or hip finally.

It was found that VAC can be smoothly photografted onto LDPE film with"film combination"system, e. g. conversion percent and grafting efficiency are 70％ and 76％, irrespcetively, with UV intensity of 5400μw/cm〓 and irradiation time of 3min. The reaction orders of polymerization rate to monomer concentration and photoinitiator concentration are about 1 and 0.76, irrespectively, showing that chain transfer reaction takes place with much ease in VAC/LDPE system.

发现利用本文所设计的方法可将VAC快速地接枝在LDPE膜表面，如在光强为5400μw/cm〓，光照3min时，转化率和接枝效率可分别达到70％和76％；聚合反应速率对单体的反应级数约为1，而对光引发剂的反应级数为0.76，说明VAC光接枝聚合中链转移反应占相当大的比例。

This model has the following three features:(1)to ensure that products are deliver on time, e.g. if products are deliver before dude date or behead dude date, then earliness/tardiness cost will occur.(2)to consider both jobbing and small-lot production situations;(3) capacity requirements date of products are varying with period and are calculated from the product's BOM and production process.

在前人研究的基础上，建立了适合于单件小批的主生产计划模型，这一模型有3个特点：(1)保证产品及时交货，也就是提前和滞后于交货期都要受到惩罚；(2)模型考虑了带有小批与单件并存的生产情况；(3)产品对能力的需求数据，考虑了分时段分布特点，并采用聚合算法从工艺路线和产品结构数据聚合而成。
