Affording the demand for the output of industry are the vast populations of the globe; hence mass production and marketing are inevitable concomitants of the machine routine.

满足工业产出需求的是全球广大人口；因此，大规模生产和营销是机器程序不可避免的伴随物。

In the same way the ordinary supply curve for a particular commodity is drawn on some assumption as to the output of industry as a whole and is liable to change if the aggregate output of industry is changed.

以同样的方式，特定商品的普通供给曲线是根据对整个工业产出的某种假设绘制的，并且如果工业总产出发生变化，则该曲线可能会发生变化。
