From the first experimental week, nine geese per groupwere weighed on an empty stomach ,and collected samples for further assess on 7th in every week;From the third experimental week, excepting for weight, three geese per group were randomly selectedand collected blood in jugular vein, then separated serum and assessed blood, endocrine andimmunological index; after collecting, geese were killed and autopsied, Spleen, bursa of Fabricius andThymus were collected for relative weight of immune organs of goose, calculated immune organs index.

从试验第一周开始，每周的第7日每组随机选取9只鹅空腹称重；统计耗料量；从试验第三周开始除称重外，每组再随机选取3只，颈静脉采血5ml，制备血清并测定血液、内分泌和免疫指标；采血后宰杀取脾脏、腔上囊和胸腺，称重，计算免疫器官指数。

For about 20 years,lots of boffins have do their best in the field,the system reliability theory has made a prominently progress,and produced many theories and methods one after another.

There were 141 CCTs from 1995 to 2000, the total number of RCT increased from 95 to 1 416 and most of studies were on digestives diseases. Most of these studies had no detailed randomization method description, only 38 (2.68%) studies provided a methodology description.

结果 该11种期刊6年间共发表了22 739篇临床研究，其中随机对照试验 1 416篇（双盲24篇，占RCT 总数1.69%），占论文总数6.23%；非随机的对照试验 141篇，占论文总数0.62%；RCT数量呈逐年上升趋势，并以消化系统疾病研究最多。

The possibility of researching gene mutation with the technique of gene chip was discussed. A new imagination to randomly determine DNA sequence in different living beings with the technique of gene chip was advanced. In this way, whether the encoding sequence gene in DNA of eukaryon organism has some regularity was studied.

进而提出新设想——采用基因芯片技术对不同生物群体随机抽样进行DNA测序，从而探讨在真核生物DNA分子链上编码序列遗传基因的变化是否有规则而非随机的，非编码序列遗传基因是否为生物进化过程中曾经有表达能力的结构基因，并分析可能获得的结果。
