If the supplementary cost is heavy, it follows that the marginal user cost will be low when there is surplus equipment.

如果补充成本很大， 那么当有剩余设备时， 边际用户成本会很低。

Moreover, when there is surplus equipment, the marginal factor and user costs are unlikely to be much in excess of their average value.

此外，当设备过剩时，边际因素和用户成本不太可能超过其平均价值。

If both these conditions are fulfilled, the existence of surplus equipment is likely to lead to the entrepreneur's working at a net loss, and perhaps at a heavy net loss.

如果这两个条件都满足，过剩设备的存在很可能导致企业家的工作出现净亏损，甚至可能是严重的净亏损。
