PIC系列单片机片内定时器实时时钟的实现

针对直接用单片机片内定时器作实时计时不准问题，本文提出了一种可以获取与秒成整数倍关系的定时器溢出信号的方法，同时克服定量溢出中信号被其它中断暂停所受的计时影响，实验表明，在4MHz晶振下，计时误差可控制在每天14s以下，本方法也适用于一般的单片机，在PIC87系列上的实验结果表明效果很好。

Earthquake Resistant Engineering and Application of Seismic Zonation Map of China

China is a country with high seismieity. It is very important for industry and structure to fortify against earthquakes. In this paper the outline of seismicity in China, the criteria for fortification against earthquakes and the contents of seismic zonation map of China are described. The contents of seismic safety evaluation for major construction projects, such as large dams, large bridges, long distance pipe lines for transporting oil and natural gas, nuclear plants, petrochemical enterprises and so on, are presented. Some geological disasters caused by destructive earthquake, such as earthquake-caused collapse and landslide, liquefaction of saturated soll and earthquake fault and so on, are also presented. Preventive countermeasures for these disasters are discussed.
