从作者性别批评视角看简·爱和吕蓓卡的人物形象差异

简·爱与《名利场》中的女主角吕蓓卡是英国维多利亚时期文学中两个具有同样独立反叛意识但被作者赋予不同命运结局的女人。从作者的性别视角去解读这两个传统女性形象的本质差异,能看出男女作者对女性反抗压迫行为的不同理解和价值判断,并能更好地发掘出被别的批评视角忽略或误读的文本内涵。     

中西方对青少年异性交往的态度及教育效果比较

对青少年异性交往的态度，中国自古以来比较保守、消极，西方比较开放、积极，我们应该把二者的优点结合起来．把青少年的异性交往引入健康的轨道。

The detection of structural deformation errors in attitude determination

In the determination of the attitude parameters from a multi-antenna GPS array, one of the major assumptions is that the body frame is rigid at all times. If this assumption is not true then the derived attitude parameters will be in error. It is well known that in airborne platforms the wings often experience some displacement during flight, especially during periods of initializing maneouvres, such as taking off, landing,and banking. Often it is at these points in time that it is most critical to have the most precise attitude parameters.There are a number of techniques available for the detection of modeling errors.The CUSUM algorithm has successfully been implemented in the past to detect small persistent changes. In this paper the authors investigate different methods of generating the residuals, to be tested by the CUSUM algorithm, in an effort to determine which technique is best suited for the detection of structural deformation of an airborne platform. The methods investigated include monitoring the mean of the residuals generated from the difference between the known body frame coordinates, and those calculated from the derived attitude parameters. The generated residuals are then passed to a CUSUM algorithm to detect any small persistent changes. An alternative method involves transforming the generated residuals into the frequency domain through the use of the Fast Fourier Transform. The CUSUM algorithm is then used to detect any frequency changes. The final technique investigated involves transforming the generated residuals using the Haar wavelet. The wavelet coefficients are then monitored by the CUSUM algorithm in order to detect any significant change to the rigidity of the body frame.Detecting structural deformation, and quantifying the degree of deformation, during flight will ensure that these effects can be removed from the system, thus ensuring the most precise and reliable attitude parameter solutions. This paper, through a series ofsimulations, will assess the effectiveness of the above mentioned techniques for detecting structural deformation effects on a GPS multi-antenna array. These principles are then tested with experimental data.     

论艺术概括的基本方式和三个层次

艺术概括是塑造优秀文学形象的重要手段 ,它的基本方式是必须融会在个性书写过程中 ,以个性书写为形态。艺术概括包涵三个由浅入深的层次 ,即 ( 1)通过个性概括同类现象的共同特征 ;( 2 )通过个性深入揭示内在本质 ;( 3 )通过个性显示深广的社会意义。达到这三个层次 ,文学形象便可获得深厚的内在意蕴

如何避免英文中的歧视性语言

歧视性语言是指一个社会中的强势群体把自己视为社会的规范和中心,在语言交际过程中,毫无必要地或不恰当地指出对方的性别、年龄、种族或民族等,将对方划入某一弱势群体,表示出对其的轻视、冒犯或侮辱.笔者在本文中就如何避免在英文交际的过程中使用歧视性语言作了论述.
