東南方言多半有入聲調，無獨立入聲調的以官話區為主。又，入聲調值又可因聲母清濁、送氣與否，以及韻母元音的長短再做分調。因為入聲韻尾的差異，而有分調現象的方言則是罕見，但我們卻可在江西客贛語裡，看到因入聲韻尾而分調的語音現象。江西南豐贛語因收 -k 尾，入聲調值讀為高調。江西南康、安遠的客語，即使 -k 尾完全丟失了，但還可以見到原先高調的痕跡。江西雩都的 -k 尾丟失，轉變為喉塞 -ʔ 韻尾，使得原先的高調變為高降調。再再的證據都顯示，漢語方言韻尾是有能力影響入聲調值的分化的，而江西客贛語的入聲 -k 尾即是顯著的一例。
　　本文分四個部分：一為漢語方言入聲調的性質，與大部分造成入聲分調的條件；其次論述因 -k 韻尾而造成調值差異的江西客贛語情形；再來討論另一個與 -k 尾所造成高調現象，相當類似的「韻攝分調」的情形；最末，討論 -k 尾造成高調的語音機制。期望藉由這些漢語方言分化的入聲調值的討論，能對入聲調的性質，以及入聲韻尾與調值分化的相關關係，有更進一步的瞭解。

　　In Chinese dialects, MC Ru Tone words (入聲) mostly does not have an independent position, some dialects have exceptions. Ru Tone can divide into different tones because the voiced or voiceless and the aspirated or unaspirated initials and the length of vowels. The split of the upper Ru Tone into two subtypes because of phonetic vowel length however is a very important trait in the Yue dialect (粵語). Ru Tone can be split by some phonetic reasons given above. It’s hard to see that Ru Tone is separated by final consonants in Chinese dialect. In the Gan (贛) dialect in Jiangxi (江西), the stop ending (-k) enables the ru tone to become the high register. In this article, we will discuss the relationship between the stop ending (-k) and the high register.
　　At last, we will also discuss another similar phonetic phenomenon of -k and the high register is the split of Ru Tone of rhyme-groups (韻攝).
