生实验室制取氢气时，使用制取氢气简单装置好，还是用后普发生器好？师制取氢气装置的选用是由所需氢气的量决定的。实验室制取氢气时，一般用制取氢气简易装置，只有制取大量氢气时才用启普发生器。制取氢气简易装置与启普发生器的原理相同。因为启普发生器容量大，耗酸多，
When producing hydrogen gas in a biochemical laboratory, is it easy to use hydrogen to make hydrogen, or is it good to use a post-generator? The selection of hydrogen for the division system is determined by the amount of hydrogen required. When hydrogen is produced in the laboratory, a simple device for hydrogen production is generally used, and the Kepler generator is used only when a large amount of hydrogen is produced. The simple device for hydrogen production is the same as the Kaipu generator. Because the Kaipu generator has a large capacity and consumes more acid,
