He explained how it should be changed. Our Mr. Kloman was slow to believe this, but I urged that a small glass-model furnace and two bells be made, one as the Lucy was and the other as Mr. Whitwell advised it should be. This was done, and upon my next visit experiments were made with each, the result being just as Mr. Whitwell had foretold. Our bell distributed the large pieces to the sides of the furnace, leaving the center a dense mass through which the blast could only partially penetrate. The Whitwell bell threw the pieces to the center leaving the circumference dense. This made all the difference in the world. The Lucy's troubles were over.

白话
惠特韦尔先生解释了高炉该怎么改。他们的克洛曼先生不太相信，但卡内基主张先做一个小玻璃模型炉和两个钟罩，一个照露西原来的样子，一个照惠特韦尔的建议。做好后，他下次去就用两个模型做实验，结果和惠特韦尔预言的一模一样：原来的钟罩把大块料甩到炉壁，中间留下密实的一团，风只能部分透进去；惠特韦尔的钟罩把料甩到中心，让四周密实。差别天壤，露西的麻烦就此结束。
上下文
卡内基自传中讲高炉装料钟罩的改进，用玻璃模型做小实验解决生产难题。
今日一问
下次遇到技术分歧，你能不能先做个最小模型，让实验结果说话？
