Passage 2 Every year, the American Lung Association (ALA) releases its annual report card on smog, and every year it gives an "F" to over half the nation’s counties and cities. When ALA’s "State of the Air 2002" recently came out, dozens of credulous local journalists once again took the bait, ominously reporting that their corner of the nation received a failing grade. The national coverage was no better, repeating as fact ALA’s statement that it is "gravely concerned" about air quality, and neglecting to solicit the views of even one scientist with a differing view. Too bad, because this report card says a lot less about actual air quality than it does about the tactics and motives of the ALA. The very fact that 60 percent of counties were given an ’F’ seems to be alarmist.

Two things they have in common, namely, that both belong to the order of carnivores and both serve man in their capacity of hunters.

若在一个正弦(或非正弦)信号周期内取若干个点的值,取点的多少以能恢复原信号为依据,再将每个点的值用若干位二进制数码表示,这就是用数字量表示模拟量的方法。将模拟量转换为数字信号的介质为模/数转换器(ADC)。数字影像则是将模拟影像分解成有限个小区域,每个小区域中影像密度的平均值用一个整数表示。也就是说,数字化图像是由许多不同密度的点组成的,每个点内的密度是一均值。图像矩阵是一个整数值的二维数组。图像矩阵的大小一般根据具体的应用和成像系统的容量决定,一幅图像中包含的像素数目等于图像矩阵行与列数的乘积。 512×512表示()A. 矩阵 B. 像素值 C. 图像的灰阶数 D. 图像的位数 E. 视野 [判断题]应急照明应依据《消防应急照明和疏散指示系统》(GB 17945-2010)相关规定进行设置;应急灯具应符合《特殊要求 应急照明灯具》(GB7000.2-2008)的相关要求。
