高頻預熱
英文
high frequency preheating-
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。The fifth is the observation in reality of a predicted link between increased sea - surface temperatures and the frequency of the most intense categories of hurricane, typhoon and tropical storm
第五,觀察資料顯示:海洋表面溫度的持續上升和最高級別颶風、臺風以及熱帶風暴的發生頻率之間存在著可預測關系。1. nizn ferrite was developed for using in mini high frequency dc - dc converters and inductors. we measured and analysed the parameters of the nizn ferrite, which we concern about when designing the dc - dc converter. 2. the low loss sample of nizn ferrite were chosen for design - optimization of the high frequency transformer. based on the relevant theoretical researches, the loss properties of the magnetic core material and winding were analyzed in this thesis
因此,以nizn功率鐵氧體材料為開關電源芯材為基礎,並優化各種開關電源的設計已成為國際上的熱點和技術瓶頸,本論文正是以上述背景為研究目標而開展工作的,主要進行的工作和創新有: 1 .對研製的新型高頻低功耗的功率nizn材料進行參數的測試,並針對dc - dc變換器設計關心的參數對芯材特性進行了分析,選擇在特定頻率下,功耗較小的nizn材料磁芯樣品作為變壓器優化設計的預備磁芯。The inverter apparatus controlled by pre - set voltage adjustment project has the advantages of low harmonic content, high output frequency precision, simple control circuit. therefore, this kind of project is the hot point in inverter power studying field
