While a snippet of video costs several hundred yuan, a customized chatbot costs anywhere between 50,000 and 100,000 yuan ($6,860-$13,710), said Zhang, though he believes developing costs will decrease in the future.

张先生说，一个视频片段的成本为几百元人民币，而一个定制聊天机器人的成本则在5万到10万元人民币（6860-13710美元）之间，不过他相信未来开发成本会降低。

It will be the most important investment not hyperbole, the most important investment that we've ever made in our energy security and developing cost savings and job creating clean energy solutions for the future.

这将是不夸张的最重要的投资，是我们在能源安全方面所做的最重要的投资，以及开发成本节约和就业机会，为未来创造清洁能源解决方案。

In some ways this worked well for NASA; one internal study found that developing the space-station resupply capability in-house would have cost NASA $4bn, rather than the $300m SpaceX has charged.

从某种程度上来说， 这对 NASA 来说是件好事；一项内部研究发现， 如果 NASA 内部开发空间站补给能力， 其成本将达到 40 亿美元，而不是 SpaceX 收取的 3 亿美元。
