  2. So the pipe system sends out noise because of resonance. especially the frequency 250hz of pulsating water is in close proximity to natural frequency of pipe, so the 250hz is a dangerous frequency to the pipe system. there is another reason why the noise is reached to 110db ( a ) in pump room that the noise is magnified by the cistern because of the resonance of cistern

    特別是激勵頻率為250hz的頻率分量恰好與管道系統的固有頻率相接近，其引起的管道振動對噪聲的貢獻最突出，同時也與水泵房房腔的固有頻率相接近，從而引起房腔共鳴發聲，使噪聲進一步被放大，以至於噪聲最大處高達105db （ a ） 。
  3. The active aspects include ion traps, nuclear magnetic resonance ( nmr ) technique, quantum electrodynamics cavities, josephons junctions, and semiconductors quantum dots

  4. The conclusions are as follows : the ultrasonic intensity is proportion to the laser intensity ; the ultrasonic induced by a laser line source has much more advantages than by a laser point source, such as stronger energy, higher snr, more directivity and shape ; the intensity of cfpi ' s output signal is linear with ultrasonic vibration velocity, and is effected by incidence angle and scattered angle ; snr will increase by reducing cfpi ' s bandwidth, reducing incidence angle, increasing cavity ' s length and reflectivity

    在分析點光源激勵聲表面波機理的基礎上，求出了線光源激勵的超聲振動的位移表達式，發現線光源激勵的近場區表面波具有波形好，信噪比高，指向性好，幅度強等特點。通過理論推導，得出共焦fabry - perot干涉儀的輸出光強除了與樣品表面的振動速度成正比，並與入射角和散射角有關；適當減小cfpi的帶寬，增加腔長，增大鏡面反射率，或者減小檢測入射角都可以提高系統的信噪比。
  5. The influence of various waterpower and configuration parameters on heat transfer is analysed and the rules of convective heat transfer coefficient and the ratio of heat transfer enhancement with mass flux are obtained. at the same time, we gain important results as below : as for resonance chamber with certain configuration, self - oscillation can be generated under suitable configuration and waterpower parameters. for the same configuration resonance chamber, the intensity of the self - oscillation is changed by the waterpower parameters

    當流量及壓差降低至一定程度時，共振腔還可能削弱換熱；加熱功率的提高會增加流體（水）的溫度，流體的粘度會隨著降低，這會減少對流體脈動的阻礙，使脈動衰減得更慢，而脈動幅度的增加會增強換熱，故加熱功率對有脈動的對流換熱是有影響的；自振腔產生的流體脈動頻率是自振腔固有頻率或其整數倍，流體脈動頻率過高或過低都不利於對流換熱，存在一有利於強化換熱的頻率范圍。
  6. Laser diodes : feedback and stimulated emission. cavity design ; double heterostructure concept. quantum well, wire, dot active regions. strained layers ; pseudomorphic active regions
