The death rate grew by 37%. Chinese previously did not need security door. But by now, to some place, security window has been set at seventh floor. For there are too many gangster every where, no company in China would arrange with their workwomen to go home at night. No body knows what really are the food every one have everyday. Neoteny has take place on children. Then we can imagine the situation of our health in the future. There are about 20 million girls in China are pursuing sexual work. That creates 6% of GDP aggregate, which is as much as 1000 billion RMB. This kind of activity had never appeared in the history of human being except Japan. The height of Chinese people is 2.5cm lower than that of Japanese. We can no longer see them by looking down. The small Japan became big Japan. We create 0.1 billions GDP with the payment of 1 person's life, reported by reference news. The number of death in 2003 is 136 thousands. So the number of industrial injury will be 200 thousands. It is true that our GDP is bloody. Actually, this number is a small part of the true number. The numbers which can be accounted are in nationalized business or in a big accident. In personalized business or overseas-funded enterprise, the owner do not pay attention on the death of workers. So the data can not pass to the statistical department. However, the number of death there is much more than that of the first ones. If we add this in account, the number,annually can be compared with the massacre in Nanjing.

中国人从原来不知道防盗门窗为何物，到现在防盗窗已安装到了楼房的七层以上；由于流氓遍地防不胜防，全国企业早已不再安排女工上下夜班；有毒食品已经100%的覆盖了全部行业，每天人们咽进肚子里的食物究竟是什么，只有天知晓；性早熟现象已经蔓延到了学龄前儿童，未来的身体和寿命可想而知；约2000万少女被迫卖淫，创造的收入占GDP总量的6%，相当于一万多亿人民币，这种肉体积累是世界历史上除日本之外绝无仅有的现象；中国人的平均身高比日本人低了2.5公分，由以前低头看日本人到现在抬头看日本人，小日本真的成了"大日本"；《参考消息》报道，中国每亿元GDP工伤死亡1人，2003年死亡达13.6万人，以此推算，今年工伤死亡人数将达到20万，"是名副其实的带血GDP"，其实这个死亡数字不过是冰山一角，能够统计到的死亡数字，要么是国有企业，要么是死人较多的特大事故，私企和外企平常死个把人根本到不了统计部门，而私企和外企用工数量远远超过国有企业，如果考虑到这个因素，每年死亡人数至少相当于一场南京大屠杀。

First, based on the mathematics model of comprehensive decision at present, the concept of evaluation function is introduced. Based on the thinking stability of decision-maker, the essential meaning of comprehensive decision model is discussed, therefore, and a new improved approach on the comprehensive decision model is put forward. Second, the mathematics model of interval number comprehensive decision is systematically discussed, and the ranking method of interval number based on the decision-maker's attitude is provided. Finally, the concept of valuation order relation is introduced, the valuation order relation of interval number and fuzzy number are systematically discussed in detail, it provides a new method to research the order relations of interval number and fuzzy number, therefore, these achievements can be applied in the intelligent system.

首先，针对常用的综合决策模型，给出了评判函数的概念，讨论了综合决策模型的本质意义，指出决策者的思维应具有稳定性，从而给出了综合决策模型的一种改进方法；第二，在此基础上，给出了区间数的综合决策模型，并详细讨论了基于决策者的决策心态的区间数的排序方法；第三，引入了赋值序关系的概念，详细讨论了区间数和模糊数的赋值序关系，为区间数和模糊数的序关系研究提供了新的思路与方法，这些均有望在智能系统中得到广泛的应用。

Currently we are interested in:- number 200 (133dtex)- number 100 (133dtex x 2)- number 60 (275dtex x 2)- number 40 (275dtex x 3)- number 20 (466dtex x 3)- number 15 (466dtex x 4) Could you please inform me whether you are able to produce such assortment and what will be your best price on CIF Gdynia basis.
