Question

请帮忙翻译一下。。谢谢啦

Even in China, the sustainability of railway debt arising from the program as it proceeds will need to be closely monitored and payback periods will not be short, as they cannot be for such “lumpy” and long-lived assets.

Answer 1

the sustainability of railway debt arising from the program as it proceeds

随着高铁建设项目的进行，由此产生的债务可持续性

will need to be closely monitored

需要被严格监控

and payback periods will not be short

而投资回报期会很长

as they cannot be for such “lumpy” and long-lived assets.
= because the payback periods cannot be for such lumpy and long lived assets.
因为短期投资回报不适用于这么一个整体资产、长期资产。（指的是高铁项目）

lumpy assets整体资产，必须整体一起出售或购买的固定资产

Answer 2

即使在中国,铁路产生的债务的可持续性计划推进过程需要密切的监控,投资回收期不会短,等他们不能“奢侈”的和长期资产。

追问

lumpy可以翻译成奢侈？我没有明白。。。
