Quasi homogeneous charge compression ignition (QHCCI) combustion may be with low emissions, especially for soot and NO_X, according as the most fuel which is pre-mixed is lean burnt.
准均质充量压缩点火燃烧(QHCCI)方式占总燃料多数的预混合燃料以稀薄燃烧完成，故可能有很低的排放，尤其是碳烟和氮氧化物。
Under the condition of quasi-equal level condition, density distribution of homogeneous layers are conflict with the real Earth density distribution.
在参数椭球的“准等位条件”下，匀质分层的密度分布并不符合地球的实际密度分布。
