最高的峰是base peak 但是base peak可能是分子的一部分  base peak是最高的量 作为基准 所以相对量是100%  其他量都以base peak作为基准</p>

Base peak: The most intense (tallest) peak in a mass spectrum, due to the ion with the greatest relative abundance (relative intensity; height of peak along the spectrum's y-axis). Not to be confused with molecular ion: base peaks are not always molecular ions, and molecular ions are not always base peaks.</p>

Molecular ion: In mass spectrometry a molecule of the analyte that has been ionized by electron loss, but not fragmented.<br />
