factorial effect 中文意思是什麼
factorial effect
解釋
因素效應-
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演算法，但由於其模型假定各試驗點同方差，因此不能分析散度效應。 -
We constructed fences using 2 x 2 x 2 factorial design to examine the effect patterns of food availability, predation and interspecific competition on population dynamics and spatial behavior of reed voles, microtusfortis. we expected to test two hypothesises : ( 1 ) availability of high quality food, predation and interspecific competition have independent and addictive effects on population system dynamics for small mammalia herbivore ; ( 2 ) availabiliry of high quality food could reduce home range and aggressive behavior level between individuals of microtine, predation and interspecific competition have independent effects on spatial behavior of microtine
以2 2 2析因實驗設計，在野外圍欄條件下，探討食物可利用性、捕食及種間競爭對沼澤田鼠（ microtusfortis ）種群動態及空間行為的作用，旨在檢驗下述特定假設： （ 1 ）高質量的食物可利用性、捕食及種間競爭對植食性小哺乳動物種群系統動態具有獨立的和累加的效應； （ 2 ）高質量的食物可利用性可降低田鼠個體間的攻擊行為水平，並導致其巢區減小；捕食與種間競爭對田鼠的空間行為亦有獨立的作用。 -
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。 -
Based on filling / post filling simulation in injection molding and design of experiment ( doe ) technology, the fractional factorial design method was introduced to investigate the significance of interaction among process parameters, and each factor ' s effect on the quality of mold part was also studied
摘要基於注射成型充填后充填數值模擬，結合實驗設計（ doe ）技術，應用分析因實驗設計方法，研究工藝參數之間存在的兩兩交互作用，以及工藝參數對製品質量的影響度。 -
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，並對比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築石膏的凝結，同時建築石膏的抗折、抗壓強度降低幅度減小
