中文摘要	Under the guidance of noise theory, an innovative portable metal particle monitor is designed and implemented successfully, with the sensitivity of 10/sup -6/ for metal particle in oil. Little amount sample oil is needed to determine the metal particle content. The result is displayed immediately by LCD after the sample oil's input. Compared with the current oil analysis instrument in market, this instrument has the advantages of high sensitivity, fast speed, operational convenience and low cost. The instrument principle, design and implementation are discussed, especially the low noise design of the amplifier for detection of the weak signal.
