＜正＞ Using a tethered balloon observing system, vertical distributions of number concentration of aerosols in segregated sizes in the near surface atmosphere （from ground to about 1,200m altitude） were observed at the Atmospheric Observing Experimental Base （39°48’N, 116°28’E） in the outskirts of Beijing before and during a smoke screen weather on mar. 15 and 16, 2005 with an Optical Particle Counter （OPC）. meteorological data as the ambient temperature, relative humidity and air pressure, etc. were simultaneously got with some loaded radio-sondes. Aerosol samples were collected directly from different altitudes with a remote-controlled low-volume impactor （LVI） and individual particles were analyzed with electron microscopes and an energy dispersive spectrometer （SEm-EDX）.

不创新，就灭亡”，这已经成为很多公司的座右铭。但企业究竟该如何创新？毫无疑问，已经有太多关于这一课题的著述，然而很多高管在面对一系列根本问题时仍不确定该如何操作。例如，当公司倾力发展核心业务时，他们如何让一个前景看好的方案得到必要的资源？为什么那么多绝妙的发明失败了，而另一些似乎平平无奇的创意却获得了成功？这些基本问题正是最近两本新书--杰勒德·泰利斯（Gerard J. Tel is）的《不懈的创新：如何打造一种称雄市场的文化》（Unrelenting Innovation：How to Build a Culture for market Dominance）和罗恩·阿德纳（Ron Adner）的《广角镜头：一项创新新战略》（The Wide Lens：A New Strategy for Innovation）--的主题。这两本书相映成趣：前一本着眼于公司的内部工作，而后一本聚焦于公司的外部环境。
