介绍产品筛选。一个合适的产品筛选实际上是一个过程，而不是一个测试。作为一个过程，它得到维护和不断验证，以确保它达到定义的目的。该过程应用于产品，以诱导具有已知故障机制的产品在产品部署到现场之前在受控情况下发生故障。如果这个过程应用得当，那么与屏幕故障机制相关的现场所有婴儿死亡率故障都将被消除。

Describes product screening. A proper product screen is actually a process, not a test. As a process, it is maintained and constantly validated to ensure it achieves the purpose for which it was defined. This process is applied to a product in order to induce products with a known failure mechanism, to fail in a controlled situation before the product is deployed in the field. If this process is properly applied, then all infant mortality failures in the field, associated with the failure mechanism(s) for the screen, will be eliminated.
