1 ) the harsh natural environment, the scattered residents, the inconvenient transportation and inaccessible information, 2 ) the low level of production ability and insufficient educational investment ; 3 ) the negative influence of traditional ideas and the high illiteracy rate of female number ; 4 ) the aim of education can not connected with local demands, the educational contents is complicated, difficult, narrow and out - of - date, the educational ideas and educational means is often outdated, and all the teachers " quality is not in high, especially the great short of hui nationality teachers, and the great different distribution of educational resource between urban and rural
本研究認為，固原地區回族女童教育落後的原因是多方面的：自然環境惡劣，居住分散，交通不便，信息閉塞；生產力水平低，教育投入少；傳統思想影響嚴重，女性文盲人口多；教育目標不切當地方實際，內容「繁、難、窄、舊」 ，教育觀念和手段落後，教師隊伍整體素質不高，回族女教師奇缺，城鄉教育資源配置差別大；家長文化素質不高、家教能力欠缺，家庭子女多，教育支付能力低。女童自信心不足，容易受外界因素影響。By successful solution of non - linear magnetic fields and revision of the program, we can reach following conclusions : in the computation of nonlinear magnetic fields, if iteration method is used, under - relaxation is necessary when amending the permeability distribution in soft magnetic materials ; and when < wp = 5 > calculating the equivalent current density in permanent magnets, under - relaxation is not a necessity ; when searching for permeability values by interpolation method on the demagnetization curve of soft magnetic materials, if a fixed saturation point is set, around this point an abrupt change of permeability values will be obtained ; this sudden change may cause a little problem in the smoothness of magnetic field distribution ; because the magnetic circuits of microwave tubes are too complicated, in the author ' s view, to describe the working state of a magnet system, the working points of magnets can not do it properly but average energy production of magnets will serve ; as to indicate the quality of a magnet system design for microwave tubes, the efficiency of magnetic energy utilization will be a very good criterion
由此得出結論，在非線性磁場計算中：採用迭代法的情況下，在各迭代循環之間進行磁導率修正時，一個欠鬆弛迭代過程是必需的；對永磁體中的等效電流修正時可以不作欠鬆弛迭代；在純鐵的磁化曲線上指定某一個固定的磁感應強度為磁飽和值，會使得插值求出的磁導率在該磁飽和值附近有一突變，這一突變對計算結果中磁場分佈變化的光滑性稍有影響。在微波管磁系統設計中，由於微波管磁路比較復雜，作者認為磁體的工作點並不能很好地反映磁體的工作狀態，而採用平均磁能積為衡量磁體工作狀態的標準更加符合微波管磁系統的實際情況；要表示磁系統設計好壞的程度，則用磁能利用的效率為標準更好。The influence of catalyst on the copolymerization of epoxy and cyanate was investigated, and the mechanism of their copolymerization was discussed. the catalyst can obviously accelerate the curing of the resin to decrease the curing temperature. the three kinds of reactions ( cyclotrimerization, co - reaction and polyetherification ) in their copolymerization are not simultneous and independent to each other. in the lack of cyanate functional group, the main structures are oxazoine and polyether structure in the cured resin, and the triazine ring structure is of miner importance
研究了催化劑對環氧樹脂與氰酸酯樹脂的共聚固化反應行為的影響，並初步探索氰酸酯/環氧固化的反應歷程.研究表明，催化劑能明顯地促進其固化反應，降低固化溫度，縮短固化時間；氰酸酯與環氧共聚反應歷程是首先氰酸酯三聚反應生成三嗪環結構，然後三嗪環開環與環氧共聚反應，最後是未能參與共聚反應的環氧官能團在唑啉結構和三嗪環的催化下發生聚醚化反應；在氰酸酯官能團欠量的條件下，固化樹脂中主要是唑啉和聚醚結構，而三嗪環結構的含量很少The bridges are pivotal stronghold of the whole road. it becomes more and more popluar that some existing bridges betray multifarious structure damage and the limitations below the anticipative functions inevitably by reason of structure aging or vehicle load increasing or adverse environment or maintenance deficiency. lt results in not only the local bottleneck of the line and hidden trouble to the passing vehicle if the defective bridges are not duly maintained and reinforced. as a result, the bridge evaluation is specially important to the maintenance and strengthening. futhermore, we can not demolish and rebuild only but adop corresponding measures according ad temporal condition when the bridges are deemed to have defectiveness. so it accords with the situation of a country that the reinforcement and other upgrade measures aim at the bridge attention
由於結構自然老化、車輛荷載增加、不利環境影響以及養護維修欠缺，一部分橋梁不可避免地要暴露出各種結構損傷和既有橋梁不滿足規定功能要求的問題越來越普遍。如果這些技術狀況不佳的橋梁得不到及時的維修和加固，不僅會造成整條線路的局部瓶頸，而且還會對通行的車輛造成極大的隱患。因此，橋梁評估作為橋梁維修和加固的依據就顯得尤為重要；此外出現了技術狀況不佳的橋梁應根據實際情況採取相應的措施，而不能僅僅採取拆除重建的方法，因此加固和其他升級方法是目前比較符合中國國情的橋梁改造措施。The results shows that the concentration of acetylcholinesterase in earthworms was low, it was not steady and its loss during purification process was great
且純化過程中損失較大，結果欠佳；活化載體共價結合法固定得到的乙酰膽堿酯酶酶膜活性高，酶不易損失，重現性好。This thesis mainly researches on pattern of telecommunication management analysis and decision support in our fix - line telecommunication operation. first the construction of data warehouse is discussed, analyses the data of the base information, billing information and calling detail record of the customer, and then discuss the methods of data mining including defining the operation scope, sampling, data analysis, modeling and implementation we put focal point on the choice and design that the model of data mining, on the basis of the already studies of abroad and the actual needs of fix - line telecommunication company. three data mining models of our fix - line telecommunication operation are putted forward : customer value model, customer retention model, and customer segment model
