     we performed a detailed study of the high-mass clump interacting with bubble n10 based on the spectral lines 12co(3–2), hco+(4–3), n2h+(4–3) and ch3oh(7(0,7)–6(0,6)) and continuum emission data at 450 μm and 850 μm released by cadc and spitzer. a blue-shifted optically thick line12co(3–2) seems to indicate that the outer envelope of the high-mass clump is still falling toward the center. detection of ch3oh(7(0,7)–6(0,6)) suggests that a hot core has formed around yso n10-7. the position–velocity diagram of n2h+(4–3) indicates that the cold dense core of the clump has not been destroyed by the star formation activities. the mass of n10-7 is about 27.44 m . the ratio hco+(4–3)/n2h+(4–3) in the outer part of the clump is larger than that in the inner part of it. the reason may be that the co abundance relative to n2h+(4–3) is increased in the outer part of the high-mass clump, and more n2h+(4–3) were converted into hco+(4–3).
