| 摘 要： | 目前,绘图软件所绘制的岩性剖面图中,将所有岩性框架均用矩形来表示。对于陆源碎屑岩来说,这样既不能表示出其粒度变化情况,又不能反映出它形成时的沉积动力学特征。为了弥补绘图软件的这些不足,提出用曲边矩形代替矩形来绘制陆源碎屑岩岩性框架,并以表示正粒序陆源碎屑岩岩性框架的曲边矩形为例,详细推导了其曲边的函数表达式,为绘图软件的二次开发提供了陆源碎屑岩岩性框架绘制的一种数学模型。

| Abstract: | At present,the shortage of lithologic section drawn by the graphic software lies in expressing all rocks as rectangles frame,which failed to express not only the granularmetric change of the terrigenous clastic rocks but also its characters of sediment dynamics.In order to remedy this shortage,it was put forward that the frame of terrigenous clastic rocks should be expressed as the collaring rectangle instead of rectangle.Take the normal graded granularity for example,the curve function of the collaring rectangle was derived,which can provide a kind of mathematic model for drawing the lithologic frame of terrigenous clastic rocks in the second development of graphic software. |
