简介:介绍配对的Haar变换被显示出的最近的不同性质。不完全地指定的布尔功能的NonpolynomialHaarPxpansion被介绍了。把配对的Haar光谱的一些应用基于上述性质和扩大被建议了。为Haar对光谱从的计算的算法拆散为不完全地指定的布尔功能的系统的立方体也被开发了。

简介:戏曲演员在舞台的最终任务,是扮演剧中角色,通过"唱、念、做、打、(舞)"等各种技艺手段,去型造舞台人物形象。"唱、念、做、打",按照《粤剧大辞典》的权威诠释:"唱,是指演员的唱功,对演唱的技巧和唱腔的处理。念,指念白的功夫,戏谚有‘千斤白四两
简介:摘 要:侏罗纪时期气候发生过剧烈变化,能划分为早侏罗世早中期、晚期,中侏罗世早、晚期以及晚侏罗世等5个演化阶段。早侏罗世我国北方为温暖潮湿气候;中侏罗世早期,气候属于潮湿类型;中侏罗世晚期,转变为半潮湿-半干旱气候;晚侏罗世时期,东北北部地区显示为潮湿气候,华北和西北地区处于半干旱-干旱气候。东南地区早侏罗世以温湿气候为主;中侏罗世早期为半温湿气候,并存在短暂干热气候,中期开始逐渐向半干热气候过渡;晚侏罗世时期,南部气候为干燥炎热。西南地区早侏罗世早期为半潮湿温凉或湿热型气候;早侏罗世晚期为半干旱炎热气候环境;中侏罗世时期为以半干旱-干旱为主伴有湿润的气候特征;晚侏罗世时期,属半干旱半湿润气候。西藏—滇西地区早侏罗世为偏潮湿的热带和亚热带气候;中侏罗世时期,为炎热气候;在晚侏罗世羌塘盆地的气候演变为热-干型。
简介:×××同学问:《雄伟的人民大会堂》一文,作者运用了哪些说明方法来突出其特征?答:本文的标题是“雄伟的人民大会堂”。为了突出“雄伟”这一特征,让人们对其雄伟、壮丽能有一个鲜明具体的印象,作者较多地运用了数字说明的方法。有时是单独使用列数字的方法。如开始的总述部分,就用了两个精确的数字(建筑面积达171800平方米,体积有1596900立方米),说明大会堂规模之大,是“首都最宏伟的建筑之一”。对万人大礼堂的具体说明,用了更多的数字说明。如“宽76米,深60米,中部高33米,体积达86000立方米”,“70条瑰丽的光芒线和40瓣镏金的向日葵花瓣”,“天花板上钻了几百万个孔”,等等。对宴会厅的说明也用了不少数字说明,这里就不再一一列举了。
