熱噪聲源
英文
thermal noise source-
Compared with traditional mechanical and optic gyros, hrg has such advantages as no high speed circumvolving or moving parts in structure, no warm - up time and short start - up time, wide signal band in frequency, low excursion noises, great endurance in over loading, nuclear radiation and short time power off, small bulk, light weight, low power cost and long life, which is suitable for space applications
與傳統的機械陀螺和光學陀螺相比，半球諧振陀螺具有如下優勢:結構上無高速轉子、無活動部件;不需預熱，啟動時間短;信號頻帶寬，漂移噪聲低;能承受大的機動過載;抗核輻射，並可經受短時間電源中斷的影響;體積小，重量輕，功耗低，壽命長，非常適合空間應用。As the range increases thermal noise tends to take over as the major source of inaccuracy.
當射程增大時，熱噪聲將成為一個主要的誤差源。That is the reason that all over the countries have never stopped researching for mask jamming technology of radar. at present, the mask jamming source mainly comes from the thermal noise and zener avalanche noise of semiconductor devices. but the noise ’ s quality isn ’ t stabile because of the differences of semiconductor devices each other and the changes of exterior conditions
目前採用的遮蓋性干擾的噪聲源主要來自半導體器件本身的熱噪聲或齊納雪崩噪聲，但各器件本身的不一致性和外界條件變化等因素使噪聲輸出質量不穩定;同時由於此類信號不能再生，不利於科學研究。This paper try to obtain various noise - control measures applied to different situations through analyzing noise transmission characteristics of heat pump units under natural conditions of ventilation and cooling, in practice, the noise pollution of the hot pump units has been reduced obviously by effective measures

但單臺或多臺熱泵機組的工作噪聲易對周圍環境產生一定影響，已成為近期城市中一類帶有普遍性的固定源噪聲污染問題。This will be dealt with in this paper. the discrimination for noise source from qn700 indicates : the fan noise ( 625hz ), the electromagnetism noise ( 962hz ) and the burning noise are the main noise sources
對汽車燃油空氣加熱器中具有典型代表結構的qn700型樣機的測試分析表明：風扇噪聲（ 625hz ） 、電機噪聲（ 962hz ）和燃燒噪聲是加熱器的主要噪聲源。Presently, in the design of the ventilation and heat dispersion of the cabin, only necessary wind quantity is considered simply, while detailed mode and efficiency of the ventilation and heat dispersion are not considered too. so maybe the resource is wasted by the equipment, while noise is increased and stealth ability is decreased
目前，在機組艙通風散熱的設計中，只是簡單地考慮了散熱所需的風量，而沒有考慮通風散熱的具體方式和效率，這不但造成了整個裝備對資源的浪費，同時還增加了機組艙的噪聲和降低了機組艙的隱身能力。A kind way of current sharing composed of the droop method and the master - slaver method based on thermal stress and the random of the master is given, in this system an extra controller is attached ; all the software and hardware on can fieldbus communication part have accomplished, which guaranteed the communication of the charger high reliability and high real - time. the source and types of the noise from switching power are analyzed and some methods are introduced to restrain noise and strengthen the system performance of interference rejection
