Inspection of this equation reveals that detector sensitivity for a given configuration is primarily determined by two terms 對這個表達式的研究表明,對一給定值的裝置,檢測器的靈敏度主要由兩項決定。
But since then , detector sensitivity has improved 1 , 000 - fold , and instrument builders expect soon to wring out another factor of 1 , 000 即使是當(dāng)時最佳儀器的靈敏度,與測得假定的暗粒子所需的靈敏度相比,僅及1 / 1000 。
