在清末社会变革中,戏剧与公益慈善构成田际云事业的核心,其戏曲表演与公益慈善深度交织,相互成就。他一方面以自己在梨园界的声誉首开京城义务戏之先河,为北方公益慈善事业的展开奠定基础;另一方面尽国民“义务”,为自己的戏剧事业开拓新路径,树立社会教育者新形象。田际云的生活世界是复杂的,无法简单以戏剧与公益慈善等场域划分。在清末民初波诡云谲的局势下,他不断调整自己的事业发展方向,做出有利选择。他深刻参与社会变革,在一定程度上推动社会改良;在革故鼎新的时代,他主动迎合时局,既接受社会教育,也参与社会改造。

清末北京义务戏深受戏剧改良运动影响,其演进过程呈现出多种新元素,不仅促进戏剧改良,而且在一定程度上推动社会风俗改变。一方面,戏剧改良运动促进艺人与报人合作开演义务戏,推动义务戏在传统表演形式中增添许多近代元素,如戏剧内容革新、舞台元素多样化和女性群体加入。另一方面,义务戏受到近代启蒙思想影响,热心助赈的新艺人成为义演主体,成为启蒙与宣教活动的实践者。同时,义务戏也促进社会风俗改良,艺人社会形象得以重塑,其社会地位也有所提高。清末北京义务戏体现出传统与现代的交织,也是本土文化与外来文化碰撞的结果。

本文采用开放式氮氧化物(NO_(x))传感器控制单元对自研的NO_(x)传感器敏感探头进行了标定测试。通过上位机软件对NO传感器敏感探头的各项数据进行采集和分析,提出了一种利用主泵电流对NO_(x)体积分数测量过程中O_(2)干扰进行补偿的修正方法,并推导出了计算公式。实验结果表明:该方法能够建立起更好地测量泵电流与NO体积分数值的对应关系,克服了在测量过程中的O_(2)干扰,显著提高了NO传感器的测量精度。

A coastline is defined as the average spring tide line. Different types of seacoast, such as sandy, silty, and bio- logical coast, have different indicators of interpretation. It is very difficult to develop a universal method for interpreting all shorelines. Therefore, the sandy, the silty, and the biological coast are regarded as research objects, and with data mining technolog,found the rules of interpretation of those three types of coastlines. Then, an intelligent coastline interpretation method based on rules was proposed. Firstly, the rules for ex- tracting the waterline in Landsat TM/ETM＋（Thematic Mapper/Enhanced Thematic Mapper Plus） imagery were discovered. Then, through analyzing the features of sandy, silty and biological coast, the indicators of interpreting different types of shoreline were determined. According to the indicators, the waterline could be corrected to the real coastline. In order to verify the validity of the proposed algorithms, three Landsat TM/ETM＋ imageries were selected for case studies. The experimental results showed that the proposed methods could interpret the coastlines of sandy; silty, and biological coasts with high precision and without human intervention, which exceeded three pixels.
