本周已完成 2h 10m，离目标还差 40 分钟。
先看一眼形象记忆，再用填空把它们变成自己的词。
素材会从公开 RSS 更新；抓取失败时自动回到内置课程。
In a modern hardware team, a good test is more than a measurement. Engineers define a repeatable protocol, protect data quality, and explain what the results mean for the next design decision.
When a result looks surprising, the first question is not “who made a mistake?” It is “can we reproduce it?” A shared procedure gives the team a common starting point. It also makes handoffs between design, applications, and qualification much smoother.
That discipline does not slow innovation. It gives engineers the confidence to move quickly because every decision is backed by a clear record.
先听示范，再录一遍。支持转写时会显示文字，否则可直接回听。
你需要用 30 秒说明：测试完成到哪一步、发现了什么、下一步是什么。
“So far, we’ve completed the electrical test protocol. We found a small temperature drift during the second cycle. Next, I’ll repeat the test and share the data with the qualification team.”
不用追求长，先把事实、影响和下一步说清楚。
写完后点击“获取反馈”，我会从清晰度、工作词汇和下一步表达三个角度帮你改。
