The influence of retarder on the seaing time and ultimate strength of gypsum plaster was investigated in this paper . the experimental results indicate that the effect of single retarder , such as citric acid , is inferior to that of composite retarder which was made of blending citric acid with a few portland cement ( about 0 . 5 ? , by weight ) . the effect of different water - retention agents , such as polyvinyl alcohol ( pva ) , carboxymethyl cellulose ( cmc ) , and na - bentonite , etc . , was also studied , and the results demonstrate that by means of adding organic and inorganic water - retention agent simultaneously the water - retention of plastering slurry can obviously be improved . the optimal mix proportion of gypsum plaster suitable to finish coat of walls and ceilings of buildings has been got by use of factorial experiment with orthogonal array accounting for interactions between factors each other 研究了分別以檸檬酸、檸檬酸與普通硅酸鹽水泥復合物作緩凝劑,調節粉刷石膏的凝結時間,并對比2種緩凝體系對石膏抗折、抗壓強度的影響.比較不同保水劑(聚乙烯醇、羧甲基纖維素)以及相同量的保水劑在不同工藝流程下保水效果上的區別.探索了有機保水劑和無機保水劑對粉刷石膏的保水性的影響.結果表明,檸檬酸與普通硅酸鹽水泥的復合緩凝劑比單純的檸檬酸更能有效地延緩建筑石膏的凝結,同時建筑石膏的抗折、抗壓強度降低幅度減小

This paper mainly research how to take full advantage of various quality tools , including work - site management 5s , traditional seven quality tools , process capacity analysis , poor quality cost analysis and more complicated statistics factorial experiment and variance analysis , to lower products cost and improve revenue through process deviation reduction , process cycle time reduction or process output improvement 該論文主要研究如何運用各種質量持續改進工具：現場管理5s法、傳統的七種質量工具、過程工序能力分析、質量成本分析法以及較復雜的統計學知識因素試驗和方差分析持續降低過程偏差，減少過程周期時間或增加過程產出，從而降低產品成本，增加收入。

It ' s unable to estimate the dispersion effects . in this paper , we consider a model of heterscedasticity , and present a new algorithm on the basis of hamada and wu ( 1991 ) ' s iterated algorithm on estimation of location effects , combining brenneman and nair ( 2001 ) ' s mh method on estimation of dispersion effects . this algorithm of model selection and simutanious estimation of location and dispersion effects analyze unreplicated factorial experiments with censored data 本文考慮試驗點是異方差的模型，在hamada和wu ( 1991 )位置效應分析方法的基礎上，將brenneman和nair ( 2001 )散度效應分析的mh方法融入其中，對帶有截尾數據的無重復因子試驗給出了模型選擇以及同時估計位置效應和散度效應的迭代算法，改進了hamada和wu的方法。

Its basic principle is to regard selecting or do not selecting a feature as a two - level independent factor ; the parameters of svm as continuous noise factors ; the accuracy of the svm model as the dependent variable ; to employ a fractional factorial experiment design to form the experiment which combines the two - level factors and the noise factors ; after the experiment is finished , to analyze the effect of each factor to determine the effective independent factor combination , namely the best feature combination for the svm model 其基本原?為：將一個輸入變?的選取與否視為一個二水準的實驗因子；將一個? ?視為一個?續的噪音因子；將模型的準確?視為因變? ； ?用部分因子實驗設計得到實驗因子與噪音因子的組合；實驗完畢后，進?因子的效果分析，以決定最佳的實驗因子組合，即最佳的輸入變?組合。

This article describes the development process of surrogate models and introduces some experiment design methods and approximation approaches that can be used for a mdo surrogate model , they are full factorial experiment design , orthogonal experiment design , uniform experiment design , central - composite experiment design , and polynomial response surface method , kriging method , radial basis function method and artificial neural network 為此本文中分別介紹了正交試驗，均勻試驗以及中心復合試驗等幾種試驗設計方法，以及多項式響應面， kriging ，和徑向基函數等幾種數學近似方法。并且通過構造描述機翼展向升力分布的代理模型，對上述幾種方法作了對比分析。

Thus , the analysis of dispersion effects from unreplicated factorial experiments has become an important research topic in recent years . brenneman and nair ( 2001 ) proposed a method to estimate dispersion effects ( mh ) through concluding several used methods and study the performance of the method through simulation Brenneman和nair ( 2001 )在總結了許多學者工作的基礎上，給出了一種散度效應的估計方法( mh方法) ，并用模擬試驗說明了其方法優于其他方法。

However the analysis of both location and dispersion effects in unreplicated factorial experiments with censored data has not been studied widely . hamada and wu ( 1991 ) proposed a iterated method to estimate location effect under the condition of homogeneity of variances Hamada和wu ( 1991 )給出了此條件下鑒別和估計位置效應的迭代算法，但由于其模型假定各試驗點同方差，因此不能分析散度效應。

Methods 1 ) statistic methods including factorial experiment was carried out to optimize the major conditions for sample management , and the feasible negative and positive control for fcm analysis of cd62p expression were check out 方法1采用濃度梯度法優化gprp濃度條件，采用析因設計優化凝血酶濃度和37孵育時間條件，尋找最佳陰、陽性對照。

Hamada and wu ( 1991 ) identified important location effects by imputing the censored data . and bihua has considered identification of both location and dispersion effects from unreplicated factorial experiment with right - censored data 對于這樣的截尾數據， hamada與wu ( 1991 )通過對截尾數據補值，給出了模型選擇以及鑒別和估計位置效應的方法。

In 1986 , the staff of corbana ( national association of banana growers ) summarized all the trends found in previous experiments and designed a big factorial experiment which has been in the field for more than 4 years 1986年，全國香蕉種植者協會（ corbana ）的人員總結了以往試驗發現的趨勢并設計了大型析因試驗，已在田間做了4年。
