  1. Secondly, ground on the duct noise control, the delayed - lms algorithm, which is actulized easily, is brought forward, then the simulation on pc is achieved. it is shown from the computer simulation that for the single frequency noise, there will be a good effect when choosing the suitable parameters ; but for the narrowband noise, the effect will become worse with increasement of the bandwidth. this result is helpful to analyze the parameters influencing anc

    結果表明： （ 1 ）隨著濾波器長度的增大，系統收斂速度變快； （ 2 ）隨著值的增大，系統的收斂速度增大，但是當值超過某一范圍時會引起系統的發散； （ 3 ）次級通路的延遲數與初級噪聲頻率有關； （ 4 ）對于窄帶信號， dlms演算法可以取得一定的降噪量，但是隨著窄帶信號帶寬的增大，降噪效果明顯變差。
  2. Adsl is a new modem technology ( the bandwidth is from 25. 875k to l. lmhz ) that converts existing copper telephone lines into access paths for multimedia and high speed data communications, and maintains the regular telephone voice services. adsl provides data rates that expand the best existing access capacity ( isdn ) by a factor of 60 or more, and the best existing common analog access capacity ( v. 34 modems ) by a factor of 300, without requiring any new cabling

    它具有傳統模擬modem和isdn無可比擬的速率優越性，其接入速率是isdn的60倍，是現有模擬modem （ v . 34 ）速率的300倍，最大8mbps的下行傳輸速率和最大1mbps的上行傳輸速率，其原因是因為它使用了超過了傳統modem的頻帶范圍（ 25 . 875k到1 . 1mhz的頻帶） ，採用了先進的編碼和調制解調技術。
  3. In general, the upward amplitude curve " curvature is larger, and it changes quicker. on the contrary, the downward is smaller and slower ; because the flare force contains the square of the wave elevation velocity, it results in an difference between the flare force frequence and the associated moving frequence ; the flare force decreases the downward amplitude of heaving oscillations ; the speed of ship has an ignorant effect on the peak values of three calculated values, but there is an obvious effect on the oscillating frequence ; the wave amplitude has an effect on the ship motion, and there is an linear relation between the oscillating amplitude and the wave amplitude on the whole. by the way, there are some experiences and lessons according to the progress calculation : before the calculation of the ship motion, we should checkout the balance in a calm water firstly, namely, the whole displace of ship and the longitudinal position of the center of gravity must be consistent with the draft in calm water, or else, the calculation may show the " floating " phenomenon ; the mixed language programming has a lot of virtues, but it exists a fatal limitation - the debug of dll

    研究表明：在某些頻率范圍內相關水動力系數基本不隨吃水變化，只有超過某一頻率后水動力系數的值才會出現差異；在橫搖方向，水動力系數並沒有隨著吃水的變化發生規則變化，而是出現了波動現象；近船首剖面的水動力系數計算表明，水動力系數的波動非常大，並遠遠偏離了平均位置的水動力系數值，值的變化速率也不盡相同，總的看來，上振幅曲線曲率較大，變化較快，下振幅曲線曲率較小，變化較慢；外飄力和波面運動的速度的平方項有關，導致其振動頻率和相應運動方向的頻率不同；外飄力使升沉向下運動的幅值減小；船速對三個計算量的峰值影響甚微，但對振動頻率有明顯影響；波幅對船舶運動的影響是明顯的，船舶運動的幅值基本上和波幅成線性關系。
  4. Spectrum analyzer tracking generator which extends operation over 1 ghz frequency range 0. 15 to 1050 mhz

    基礎上發展而來的，它的頻率范圍超過1ghz 0 . 15mhz 1050mhz
  5. What is an active protection, elementary : mike or receiver of the signal - an amplifier, 1 transistor - a capacitor with changeable resistor - an output on speaker or emitter

    頻率范圍超過100千兆赫，採用材料反射體屏蔽，具有高介電常數，導磁性，水或鎂7分水作為遮蓋金字塔，填充物- - -一個吸收器- - -石墨，碳。也可以建造積極保護方式電容器。
