解釋
三級檢波-
The concept of good codes and proper codes for both error detection and correction is presented. it is shown that the binary perfect codes and the primitive double - error - correcting bch codes and their extended codes are proper for both error detection and correction. the primitive triple - error - correcting bch codes with length 2 " " - 1 and their extended codes are proper for odd m > 5, not for even m > 6
本文的主要工作是把目前關于只檢錯時線性碼不可檢錯誤概率的研究推廣到同時糾錯和檢錯的情況，獲得了同時糾檢錯時線性碼不可檢錯誤概率的解析表達式，提出了糾檢錯好碼和最佳糾檢錯碼的概念，並證明了二進制完備碼及其擴展碼是最佳糾檢錯碼；糾正兩個錯誤二進制本原bch碼及其擴展碼是最佳糾檢錯碼；碼長n = 2 ~ m - 1 、糾正三個錯誤本原bch碼，當m為大於等於5的奇數時是最佳糾檢錯碼；當m為大於等於6的偶數時，不是最佳碼。 -
Presents the simple but highly reliable on - line detection of ultrasonic transducer clamping capacitance based on the impedance circuit model constructed through the impedance characteristics of the ultrasonic transducer under triple harmonics, and concludes from experimental results that this method can be used to effectively detect the variation of clamping capacitance while the transducer is operating, and the matching inductance can be dynamically regulated according to the results of detection, and dynamic matching can therefore be achieved in the real sense at the end of the transducer to improve the overall performance of the whole system
為了解決大功率超聲應用的換能器電端匹配問題，分析了超聲波換能器在諧振頻率三次諧波下的阻抗特性，給出了超聲換能器三次諧波下的阻抗電路模型.並根據阻抗電路模型建立了對超聲換能器的夾持電容實現在線檢測簡單、可靠性高的方法，實驗證明該方法有效的.該方法可以在換能器工作過程中隨時檢測夾持電容的變化，根據檢測結果對匹配電感進行動態調整，實現真正意義上的換能器電端的動態匹配，從而大大改善匹配質量，提高系統的工作性能
