Although a great deal work have been done to theoretical research of beams with two cantilevers structure, we paid attention to test systems used in beams with two cantilevers mechanics test less. And school, incorporated teaching and researching, needed this small or medium octavo test system to develop teaching and researching. So joining in this development item of test system established by school, the thesis aimed to develop a set of simple, economical and applicable test system of reinforced concrete beams with two cantilevers to serve for teaching and researching, and make it a powerful supplement in structural experiment field.

我们尽管已经对双悬臂结构的理论研究做了大量的工作，但是对双悬臂结构进行力学试验的试验体系相对较少，而作为教学与研究为一体的学校迫切需要这样的中小型试验测试体系开展教学与科研，故本课题结合学校已经立项的试验系统开发项目力图研制开发一套简单、经济、适用的钢筋混凝土双悬臂梁试验系统为教学与科研服务，同时作为对双悬臂梁结构试验领域的补充。

Form April to July, 1975, and 1977, a series of artificial stimulating precipitation experiments by seeding clouds with, metaldehyde and silver-iodine from the ground by the small rockets were carried out in Gutian reservoir region of Fujian province.

1975年和1977年4—7月，在福建古田水库地区进行了由小火箭携带介乙酸和碘化银播云的人工降水试验，采用区域回归随机试验方案，利用统计方法检验效果。试验对象主要是系统天气影响下的降水性层状云和积状云，以三小时时段为试验单元，总共进行了62次随机试验，其中实际作业31次，对比试验31次。

Firstly, achieving a new low and high cycle noninterfering loading, the high frequency induction local heating, the control of high cycle vibration frequency and amplitude, and the crack propagation real-time detection, an experimental system of L-HCCF at elevated temperature is established. Secondly, under two vibration frequency (50Hz and 100Hz), the contrast experiment of light and serious corrosion disc slots is done. It is found that the experimental L-HCCF life of serious corrosion disc is less than that of light's, but its dispersion is larger, and the experimental failure is identical with the service's.

首先，进行大量试验工作，提出了高低周疲劳载荷的新型加载方案，并解决了高频感应局部加温、振动调频及裂纹实时监测等多个技术难点，建立了涡轮盘全尺寸高温复合疲劳试验系统；验证试验做到了故障再现；接着进行了两种频比（振频50HZ与100HZ）的轻、重腐蚀盘的对比试验；由对榫槽第一齿进行裂纹实时跟踪，得出了枞树型榫槽的复合疲劳裂纹扩展特点规律；对榫齿断口进行的金相分析表明：裂纹首先由第一齿开始，断口系复合疲劳；试验结果显示：重腐蚀盘试验寿命较轻腐蚀盘有显著的下降，而且分散性较大。

After studying analysis of variance on single factor and double factor,this paper reveals that if the difference between levels of the primes exist noteworthily is mainly depended on the sum of its experiment effects or variance of experiment effects and stochastic difference.

0引言 在试验设计时设置重复试验，能够估计试验误差；重复试验次数越多试验误差越低，试验精确度越高。一般认为，适宜重复次数应保证使误差项自由度至少为12，否则F检验或t检验的临界值上升很快，难以呈现显著性川。

The two kinds of polysaccharose had been compared their immune pharmacolog -ical effect by a series of tests to the mice which were immunological organ weight test, celiac mononuclear cacrophage test, erythrocyte rosette formation test, EAC rosette formation test, metatarsal swelling thickness test, and lymphocyte transformation test.

In order to simply the method, we further propose using magnetic stirring with weighted ring in stead of argon sparging; using air-circulated incubator in stead of water bath for better observation and sample collection; using centrifuging in stead of filtration for extract pretreatment; using one phase of simplified bioaccessibility extraction method instead of the two-phase method for a better estimate to the in-vivo method.

爲进一步简化试验方法，建议将开放式反应槽改为密闭式；使用可调速磁力搅拌及具载重环磁石，取代昂贵之氩气搅拌；将水浴温控改为气控式，以利试验观察与采样。此外，小肠相萃取不使用吸附剂，萃取液前处理利用高速离心取代压阻较高之过滤方式。本研究二阶段试验之生物有效性皆低估动物试验RBF，建议可将二阶段胃肠体外试验方法改为单相一阶段生物有效性萃取(simplified bioaccessibility extraction， SBET)试验方法。
