  2. The classification standard of 1 - year - old transplant and non transplant seedlings of zanthxyhum planisnum var. dingtanenesis was preliminarily studied by the principal component analysis, the sampling stratification and the clustering gradually analysis

    摘要運用主成分分析法、分層抽樣、逐步聚類分析法，對頂壇花椒1年生移植苗和留床苗的分級標準進行初步研究。
  3. Peg and superfluous aa reaction by complete concatenation method, the esterify production " esterify water " and acid number were mensurated, it shows that the esterify reaction would be processed under 100 esterify temperature and with amine accelerantthe tide of esterify reaction was substantiated by ir. in the ir spectrum, the characteristic peak of hydroxy of peg and carboxyl of aa were weakened. and the ester link of peg was reinforce. the " esterify water " was increased gradually and the acid number of esterify production was debased gradually along with the extent of esterify time and the augmentation of molecular weight of peg

    通過聚乙二醇與過量的丙烯酸採用全連續法進行反應，測定酯化產物「酯化水」和酸值等宏觀手段反映出在胺類促進劑、 100的酯化溫度等條件下的酯化進程，而利用紅外光譜（ ir ）分析所反映的聚乙二醇的羥基和丙烯酸的羧基特徵峰減弱，而pea的酯基特徵峰加強等特徵進一步證實了宏觀手段所表現出來的酯化趨勢：隨著酯化時間的延長和聚乙二醇分子量的增大，產生的「酯化水」逐漸增加，酯化產物的酸值逐漸降低；從酯化時間看，當反應時間達到300min時，酯化物的酸值達到最小，而從ir分析來看，酯化物pea4的羥基峰在300min時減弱到最小， pea23在120min時羥基峰的表現出酯化基本完全。
  4. Because of the difficulty to obtain the traffic flow information of lanes at non - detector intersections in most metropolises of the world, based on the relationships between the lanes of signal - controlled intersections, cluster analysis and stepwise regression are integrated to predict the traffic volume of lanes at non - detector isolated controlled intersections. first cluster analysis is used to cluster the lanes of non - detector isolated signal - controlled intersections and the lanes of all signal - controlled intersections with detectors. then, by the results of cluster analysis, the traffic volume samples are selected randomly and stepwise regression is used to predict the traffic volume of lanes at non - detector isolated signal - controlled intersections. the method is tested by the traffic volume data of lanes of the road network of nanjing city. the problem of predicting the traffic volume of lanes at non - detector isolated signal - controlled intersections was resolved and can be widely used in urban traffic flow guidance and urban traffic control in cities without enough intersections equipped with detectors

    針對目前國內外大中城市中普遍存在的無檢測器信號交叉口車道交通流信息難于獲取的情況，基於信號控制交叉口車道之間的相關性，綜合應用聚類分析和逐步回歸法預測單點無檢測器信號控制交叉口車道流量.首先應用聚類分析將單點無檢測器信號控制交叉口的車道與有檢測器信號控制交叉口的車道交通流量進行聚類，然後在聚類分析結果的基礎上隨機選取車道交通流量樣本運用逐步回歸法預測單點無檢測器信號控制交叉口的車道流量，此方法經過南京市的具體車道流量數據驗證.此類問題的解決，可廣泛應用於城市交通流誘導系統以及交通控制系統
  5. Then in methodology, sample, measurements of variables and methods are defined in order to examine hypothesis above. pror example, several indicators are used to measure a variable, and stepwise regression, cluster analysis and correlation analysis compose empirical methods
