TREE DECAY AN EXPANDED CONCEPT

To Understand the Decay Process it is Necessary to Understand Size Relationships.要了解樹木腐朽過程，必需要先了解樹木和微生物的大小關係。

For example, if a large wood- inhabiting bacterium-almost 3 microns long:-were enlarged to the size of a 6-foot man, (fig. 7), the man enlarged proportionally would be over 700 miles tall! (fig. 8)

例如，在大樹中棲息的細菌大約 3微米，放大至6英尺高的男人尺寸(圖7)，人同比例放大身高超過 700 英里(圖8)

And a giant redwood enlarged to the same proportions would be over 40,000 miles tall, (fig 9) five times the diameter of the earth!  We must keep these size relationships in mind when we consider ways to deal with the wood-inhabiting microorganisms.


如果巨型紅杉樹也同比例放大，高度將超過 40000英里(圖9)，是地球植直徑的5倍! 當我們想到木棲微生物，必需記住它們大小的關係。
