By adjusting the reducing agent, the method not only can thoroughly reduce but also can not bring insoluble solidimpurity, and leads the test result to be exact.
本发明通过调整了还原剂，即还原彻底又不会带入不溶固体杂质，使测定结果准确。

And diaphragm compared to single-screw pump can transport all kinds of mixed impurity containing gas and solid particles or fibers of the media, but also transport all kinds of corrosive substances.
和隔膜泵相比，单螺杆泵可输送各种混合杂质，含有气体及固体颗粒或纤维的介质，也可输送各种腐蚀性物质。
