Ei数据库中被《Ei Compendex》收录与被《Ei Pageone》收录的区别和辨识
|
|||
|
我们通常所称的工程索引(Engineering Index, Ei)数据库，目前主要有三个版本，即 “Ei Compendex”光盘数据库，“ Ei Compendex Web”数据库和 “Engineering Village 2”。 这三个版本中，其中的“Ei Compendex”光盘数据库，其内容与相应的国际联机数据库一致，即为Ei Compendex；而后二者（“ Ei Compendex Web”和 “Engineering Village 2”）的内容则为Ei Page One。Ei Page One收录5000余种工程期刊和会议录，涵盖并扩充了仅收录2600余种工程期刊和会议录的Ei Compendex数据库的内容。习惯上，我们将Ei Compendex收录数据称为“核心数据”，而将Ei Page One收录数据称为“外围数据”。在将工程索引(Engineering Index, Ei)数据库作为科学评价工具时，这两类数据的价值是有区别的。 由于不同版本的数据库其收录数据的著录和显示格式不同，给后二种数据库（“ Ei Compendex Web”和 “Engineering Village 2”）中Ei Compendex收录数据和Ei Page One收录论文数据的区别和识辨造成了困难。现将这二个数据库中Ei Compendex收录论文和Ei Page One收录论文的区别和识辨方式分别介绍说明如下： 一、“ Ei Compendex Web”中 Ei Compendex收录论文和Ei Page One收录论文的区别 在“ Ei Compendex Web”中 ，Ei Compendex收录论文的特征是：首先 其数据的著录格式中一定包含文摘（Abstract）项。而Ei Page One数据的著录格式中则可能没有文摘（Abstract）项；其次，也是最关键的一点是，前者含有Ei主题标识字段或赋有标题词。即Ei Compendex收录论文在Ei tagged格式中，含有CL、CV、FL、MH等Ei主题标识字段，而在Abstract格式中则含有标题词（subjects）项。现举例说明以下： 下述Ei tagged格式中文献1为Ei Compendex收录，文献2为非Ei Compendex即属Ei Page One收录，两者区别为：文献1 含CL、CV、FL、MH等Ei主题标识字段，文献2则无此项。 1.

Jump and bifurcation of Duffing oscillator under narrow-band excitation Zhu, Weiqiu (Inst of Computational Technology) Wu, Qitai | Lu, Minqing -------------------------------------------------------------------------------- SUBJECTS Oscillators (mechanical) Oscillations -------------------------------------------------------------------------------- Source: Acta Mechanica Sinica/Lixue Xuebao v 10 n 1 Feb 1994 p 73-81 0567-7718 Abstract: The jump and bifurcation of Duffing oscillator with hardening spring subject to narrow-band random excitation were examined. It is shown that, in a certain domain of the space of the oscillator and excitation parameters, there are two types of more probable motions in the stationary response of the Duffing oscillator and jumps may occur. The jump is a transition of the response from one more probable motion to another or vice versa. Outside the domain the stationary response is either nearly Gaussian or like a diffused limit cycle. As the parameters change across the boundary of the domain the qualitative behavior of the stationary response changes and it is a special kind of bifurcation. It is also shown that, for a set of specified parameters, the statistics are unique and they are independent of initial condition. It is pointed out that some previous results and interpretations on this problem are incorrect. In English 14 Refs.

It is pointed out that in small fault block reservoirs with poor seismic data and complexed structure, the comprehensive seismic interpretation technique is an effective tool for improving interpreting accuracy and reducing cost of exploration and development.
