The probability based matching(PBM) search on mass spectral data not only provides pure samples results (with forward PBM search), but also separates compounds in a mixture (with reversed PBM search).
质谱匹配概率方法不仅能提供纯样品的分析结果，而且也能区分混合物中的成分。

Objective To find out the peak bone mass(PBM) in people of Bose and provide useful reference data for diagnosis and preventing osteoporosis(OP).
目的了解百色地区骨峰值（PBM）的基本情况，为骨质疏松（OP）的诊断及防治效果评估提供依据。

Relapse rate within 10 months in 74.4 % expanded PBM patients was significant higher than that in 13.6 % non-expanded PBM patients (P< 0.01 ).
