- The measure result of the system noise show that the optical fiber hydrophone TDM system would not bring obvious noise under the current level of the detector"s noise. 系統雜訊的測試結果表明在當前探測器雜訊水平下，利用光開關實現的水聽器時分復用系統不會帶來明顯的雜訊。
- In SART（Simultaneous Algebraic Reconstruction Technique），there is no restrict to image space，so the image space』s noise will increase after the definite number of iteration. 摘要 聯合代數迭代方法（SART）對重建圖像空間是無約束的，其迭代到一定次數后，圖像空間的雜訊會不斷增加。
