以Quirk问题为基础，证明了碳现象依赖于质量通量的计算及其与压差的依赖关系，这一点最近由Liou(1997)提出并由Xu(1998)讨论。本文描述了一种两步法，其目的是在不降低给定迎风方法的接触捕波能力的情况下消除碳化现象。所得到的程序是一种准保守方法，其中修改了质量通量以消除压力相关性。
Quirk’s problem is used as a basis to show that the carbuncle phenomenon depends on the mass flux computation and its dependency on pressure differences as recently suggested by Liou (1997) and discussed by Xu (1998). The present paper describes a two-step procedure which aims at removing the carbuncle phenomenon without degrading the contact wave-capturing capability of a given upwind method. The resulting procedure is a quasi-conservative method in which the mass flux is modified in order to remove pressure dependency.
