根据社会生产力和实践第一的检验标准来考察资本主义在２０世纪的发展类型，可以发现，在２０世纪，出现了美、日、德、英法、欧洲联盟、北美自由贸易区、东亚经济区、其他发展中国家、苏联东欧转轨国家等不同类型的资本主义发展模式。在发展和停滞的两重趋势中，２０世纪资本主义的主要趋势仍然是发展。

采用类似课堂教学的学习 -测验任务 ,通过 3.实验探讨了声旁提供的部分读音信息在儿童学习和记忆汉字中的作用。被试来自北京市两所小学 2.6 0名四年级学生。实验中要求学生学习和记忆 3.生字 :(1)声旁提供汉字读音的全部信息 ,如规则一致字 ;(2.)声旁提供汉字读音的部分信息 ,如声调不同字或声母不同字 ;(3.声旁不提供汉字读音的信息 ,如声旁不知字。要求学生学习所有的字一遍后回忆生字的读音 ,共学习 3.。实验发现 ,儿童学习和记忆汉字的正确率随声旁提供的整字读音信息不同而不同 :当声旁提供全部信息时正确率最高 ,当声旁提供部分信息时其次 ,当声旁没有提供信息时最低 ;而且声旁提供的部分信息越多 ,正确率越高。结果表明 ,儿童对声旁提供的部分读音信息敏感 ,发展声旁意识对学习和记忆汉字有积极作用。

Computed tomography plays an important role in industrial non-destructive testing, medical applications, astronomy and many other fields to look inside the scanned object and to analysis its inner structures. A non-destructive testing software have been developed to efficiently detect inner flaws of space industrial components. As the core of our software, reconstruction algorithms including preprocess of raw data, re-arrange algorithm and filtered back-projection algorithms have been described in detail in this article. With real raw data from CASC of {2., experimental results verified the applied reconstruction algorithm in our software. Furthermore, forward algorithms simulating generation of fan-beam raw data are also presented in this article.

Photodynamic action of a plasma membrane-specific photosensitizer suphonatedaluminium phthalocyanine (SALPC) has been found to regulate cellular signallingpathways. The present study aimed to investigate whether SALPC photodynamicaction modulates the structure of plasma membrane proteins, and as control, of modelproteins. To check the photodynamic effect, intrinsic fluorescence of model proteinsbovine serum albumin (BSA), phospholipase A(PLA), and calmodulin weremonitored continuously during photodynamic action (SALPC 1 μM, light 14 000 luxat> 580 nm). Significant decrease in fluorescence intensity was observed in BSA and

In the past two decades, software aging has been studied by both academic and industry communities. Many scholars focused on analytical methods or time series to model software aging process. While machine learning has been shown as a very promising technique in application to forecast software state: normal or aging. In this paper, we proposed a method which can give practice guide to forecast software aging using machine learning algorithm. Firstly, we collected data from a running commercial web server and preprocessed these data. Secondly, feature selection algorithm was applied to find a subset of model parameters set. Thirdly, time series model was used to predict values of selected parameters in advance. Fourthly, some machine learning algorithms were used to model software aging process and to predict software aging. Fifthly, we used sensitivity analysis to analyze how heavily outcomes changed following input variables change. In the last, we applied our method to an IIS web server. Through analysis of the experiment results, we find that our proposed method can predict software aging in the early stage of system development life cycle.
