此困难直至1955年才为瓦尔西（Walsh A）提出的采 用锐线光源测量谱线峰值吸收（peak absorption）的 办法来加以解决。 锐线光源（narrow-line source ）:就是能发射出 谱线半宽度很窄的发射线的光源。

在大多数用例中，这是理想的行为，并被视为一个调优问题：增加maxdepth值，直到队列能吸收最高峰值负载。
In most cases, this is the desired behavior and is treated as a tuning problem: increase MAXDEPTH until the queue can absorb the highest peak loads.
以硅来说，并非穿过宽广的光谱吸收波长相同，他们的原电池反而明显地表现吸收峰值。
So rather than absorbing wavelengths more or less equally across a broad spectrum, as is the case in silicon, their prototype cell instead displays distinct absorption peaks.
X射线吸收光谱的峰值能显示出目标物质的化学键的确切性质，从而显示其组织结构。
The peaks in the X-ray absorptionspectrum can shed light on the precise nature of the target substance'schemical bonds, and hence on its structure.
