This article starts with the following aspects to study and solve the following practical problems, 1 the foundation for vessels to keep away from and withstand typhoon the article briefly introduces typhoon ' s weather characteristics, weather structure, number, naming, forming, development and its law of movement. it also discusses the ways and significance for merchant ships to collect in all - round way the information of typhoon and to make spot forecast, doubts the applicability of " barometric daily change correction table ", and puts forward the author ' s view on the judging ways on the ship ' s location in gale circle. this chapter mainly discusses the process of decision - making and the application of technology, brings forward the concepts of the objective, the policy and the ship disaster plan and disaster supply kit. this chapter also approaches the juristical relationship between master and anti - typhoon team leaders, explains the concrete meassures and the keypoit on technological application, and points out the points to be discussed in sector means of typhoon avoidence
船舶避抗臺風基礎本文根據最新資料扼要地介紹了臺風的天氣特徵、天氣結構、編號、命名、形成、發展及其活動規律；討論了民用商船全面收集臺風信息和資料作出船舶現場預報的途徑及其重要意義，對「氣壓日變化訂正表」的適用性提出了質疑，並對船舶在臺風大風圈內所處部位的判定方法提出了自己的見解；本文重點論述了船舶避抗臺風的決策過程和技術應用，提出了船舶避抗臺風的目標、方針和船舶「防抗臺應急包」船舶避臺算機標繪的概念門x討了船k勺公司防抗臺領導小組在船舶防抗臺過甜中的法叫』大系， m述了避抗臺風汀仰拙施和技術的應用要點，井指出了「扇形避離法」的位徘商郴之處。For those biological signals like echo of bat or whale, as well as man - made system signals like radar or sonar signal, the instantaneous frequency of signal component contains important information and could be used for signal model parameters extraction. so that the proper choose of transformed domain and signal characteristic extraction method is of crucial important. the ridge extraction method used for signal characterization was first proposed in the 1990s, it ' s based on the study of the phase of the wavelet ( or other linear ) transform
對于許多實際的信號，如蝙蝠發出的超聲波、鯨魚的叫聲等生物信號，以及雷達、聲吶等人造系統產生的信號而言，信號瞬時頻率的變化規律反映了信號重要的特徵，並且也是信號模型中關鍵的參數，因此選擇合適的變換域提取信號的瞬時頻率信息，並選擇合適的方法對信號進行重建是很重要的問題。According to these background, we have proposed 3 auto acoustic feedback suppressor schems : scheme i. two major algorithms - the wavelets or filter banks theories and the frequency sample filter theory have been implemented to make up the scheme a adaptive acoustic feedback suppressor
分別是:第一，基於濾波器組和頻域采樣法設計濾波器的方案。利用小波分析和重構演算法對信號進行分解並最後重構，同時在頻域直接採用頻域采樣法設計濾波器對嘯叫的頻點進行陷波處理。Air china 929, i read you 3, loud background whistle, check again
