47. Two new quenching methods are proposed as follows:1. Interrupted quenching, whereby the work-piece is first cooled in water or a water-based solution, then cooled in the muddy quenching medium,(www.Sentencedict.com) 2.

48. Experiments for hot mold shell with isolated hot spot by local water quenching in investment casting before and after pouring were conducted.

49. The quenching effect of the colors in the biology sample may lower the counting efficiency, It can be eliminated after decolorization of the sample or corrected by some other means.

50. The application, influence factors and process control of four kinds of heat treatment methods including tempering, carburizing, nitriding and induction quenching are analyzed.

51. During the laser quenching process, the hardness layer distribution remains nearly the same, aside from the input-output area.

52. To know heat treatment of vacuum, carbonnitriding, carburizing and protected quenching etc.
