使相似

In this way a new research model:frequent structure vector model derived the expression of document structure vector and weight function and constructed the calculate formula to measure similarity of the two documents. In order to improve the efficiency of mining frequency subtrees in a forest reformed the algorithm TreeMiner from data structure and miner procedure to fit to minning structure in large documents.

该方法架构了一个新的检索模型—频繁结构向量模型，给出了文档的结构向量表示和权重函数，构造了XML文档结构相似度量计算公式；同时从数据结构和挖掘程序上对TreeMiner 算法进行了改进，使其更适合大文档数据集的结构挖掘。

Items of pH, soil solution K, exchangeable k, nonexchangeable K and potassium fixation index were all determined after incubation. The results indicated similar extent and trends of transformation among three K forms, that is, decreasing content of soil solution K and exchangeable K but increasing nonexchangeable K level were observed in both CaCO3 and SrCO3 treatments of two soils. As to CaCl2.2H2O addition, pH increase was not found and the change of three K forms was not significant when application rate raised.

结果显示CaCO3的添加，除能提升土壤pH值外，亦能使土壤中三种型态钾(溶液性钾，交换性钾，非交换性钾)有显著的改变，且改变程度及趋势均甚为相似，而CaCl2.2H2O的添加不会造成土壤pH的改变，且三种型态钾并不随CaCl2.2H2O用量的增加而有显著改变的现象。

For text structure analysis,an algorithm is proposed for multi-topic text partitioning based on sequential paragraphic similarity,which can makes the abstract of the multi-topic article have more general content and more balanced structure.

在篇章结构分析里，我们提出了基于连续段落相似度的主题划分算法，使生成的文摘更具内容全面性与结构平衡性。

Artisans feared a similar decline in their position; the influx of British manufactures might destroy their small businesses, reducing them to the status of propertyless wage laborers.

工匠们因为相似的处境变差而担心，从英国流入的产品可能摧毁他们的小生意，使他们成为无产的薪资劳动力。

The enhancement of the reaction activity is attributed to the phasetransfer capability of the built-in quaternary ammonium and pyridinium salts of theMn catalyst.

分子内季铵盐和吡啶盐具有相转移能力，对于取代色烯不对称环氧化的作用与外加的吡啶盐和卤化铵的作用相似，使Mn催化剂催化取代色烯环氧化反应的活性明显提高。

The enhancement of the reaction activity is attributed to the phasetransfer capability of the built-in quaternary ammonium and pyridinium salts of theMn catalyst. The effect of the internal quaternary ammonium and/or pyridiniumsalt on the epoxidation of substituted chromenes is similar to that of the externalpyridinium salts and ammonium halides.

分子内季铵盐和吡啶盐具有相转移能力，对于取代色烯不对称环氧化的作用与外加的吡啶盐和卤化铵的作用相似，使Mn催化剂催化取代色烯环氧化反应的活性明显提高。

How this wonderful system started and what kept it working with such wonderful accuracy is largely a mystery but astronomers tell us that it is only one of millions of similar systems in spece ,and one of the smallest.

这个奇妙的星系是怎样开始的，什么使它保持精确地运行，这是一个很大的迷。但是天文学家告诉我们太阳系只是太空里几百万个相似的星系中的一个而且是最小的一个。

Similar experiences and common pursuit of development have bonded us close together. Sharing weal and woe, we have tided over difficulties side by side and forged profound friendship.

相似的经历和追求发展的共同目标使中国同阿拉伯各国风雨同舟、休戚与共、结下了深厚情谊。

Calcium has the effects of decreasing the concentration of soluble sugar and titratable acid and enhancing the firmness of fruits,has the effects of which was to some degree determined by the ca...

喷氨基酸钙的效果与此相似。在柠檬酸钙分别和Zn、B、IAA配合使用试验中，柠檬酸钙和IAA配合使用效果最好，使果实中钙含量提高了 10 4 89%。

Result At 5 and 25 mgkg^(-1), the total respiratory rate had a similar trend with tricarboxylic acid cycle and pentose phosphate pathway, T1, and T2 were higher than the control on the 1st day and then declined three days late but they had a recover on the last day. Embden-Meyer-hot-Parnas pathway had a declined trend forever. The respiratory rate of the total and three pathways were decreased under 125 mgkg^(-1). The enzyme activity of pyrophosphate-dependent phosphofructokinase, glucose-6-phosphate dehydrogenase (G-6-PDH) and malate dehydrogenase were similar to relative respiratory pathway.

测定期内，5mgkg^(-1)土、25mgkg^(-1)土浓度处理使基础呼吸速率和三羧酸循环、磷酸戊糖途径的呼吸速率均表现初期上升随后（第3天）下降但末期有所恢复的趋势，而糖酵解途径的呼吸速率则持续下降在末期小幅回升；125mgkg^(-1)土浓度处理后基础呼吸速率及3条途径呼吸速率均呈下降趋势；磷酸果糖激酶、苹果酸脱氢酶和葡萄糖－6-磷酸脱氢酶(G-6-PDH)活性变化趋势分别与其对应途径呼吸速率变化相似。
