Maintaining a caesium beam clock as the hong kong time standard and providing time signals for radio broadcasts, automatic telephone answering service and synchronisation of clocks via internet
操控銫原子鐘作為香港的時間標準,以及透過各電臺自動答覆電話查詢服務及網際網路校對時鐘服務提供報時訊號Maintaining a caesium beam clock as the hong kong time standard and providing time signals for radio broadcasts, automatic telephone answering service and synchronization of clocks via internet
操控銫原子鐘作為香港的時間標準,以及透過各電臺、自動答覆電話查詢服務及網際網路校對時鐘服務提供報時訊號;The hong kong time standard is maintained with a caesium beam atomic clock kept in the observatory
:天文臺的銫原子鐘是用來訂定本港的時間標準。This is the basis for the well-known cesium clock, presently the standard of frequency and time.
這就是眾所周知的銫原子鐘的基礎,它是目前的頻率和時間基準。The bureau international des poids mesures ( bipm ) in france determines utc based on the time information from more than 200 atomic clocks located in more than 50 time service centres worldwide. the hko is now one of these centres
位於法國的國際度量衡局根據全球五十多個授時中心的二百多個原子鐘的時間數據,訂定協調世界時,香港天文臺現在是其中之一。Early this year, the hko installed a high accuracy time transfer system which employed the global positioning system common - view method to provide time information of hko s atomic clock to bipm for utc determination
香港天文臺於今年初安裝了一套高準確度授時系統,並利用全球定位系統共視方法( globalpositioningsystemcommon - viewmethod ) ,向國際度量衡局提供天文臺的原子鐘時間數據,參與訂定協調世界時。The hong kong observatory ( hko ) uses a caesium beam atomic clock to maintain the hong kong standard time, which is the official time of hong kong
香港天文臺銫原子鐘提供的香港標準時間,是香港的法定時間標準。市民可以透過網際網路使用天文臺網路時間服務,把電腦時鐘對準香港標準時間(The hko has been providing a time service since its establishment in 1883
一九八年開始以銫原子鐘提供香港標準時間。The concept of " timing " in the article is not the clock in our ordinary living, but syntheses which is made up of some frequency source in the signal generator ( such as cs atom frequency standard, rb clock & high accuracy quartz crystal oscillator ) which produces the primary frequency, the matching input interface and the matching output interface and controlling circuit etc. for example, bits is a kind of timing equipment, which is used to control the timing of some functions
本文論及的「時鐘」概念不是指日常生活中使用的鐘表,而是由產生基準頻率的信號發生器(如銫原子頻率標準、銣鐘及高精度石英晶體振蕩器等)中的某種頻率源以及相配套的輸入、輸出介面和控制電路等組成的一整套具有特定同步定時功能的綜合體。如bits就是一種時鐘設備,它提供用在通信系統中控制某些功能的定時的時間基準設備,時鐘提供的信號稱為基準信號、定時信號或同步信號。Based on the basic principle of wavelet analysis, multi - resolution analysis of signal in atomic clock is made. the coefficients of wavelet transform for synthesis atomic time, which are weighed and averaged at different wavelet scales, are obtained. then according to reconstruction theorem, multi - resolution synthesis time scale can be reconstructed. since the signal of atomic clock has been analysed by multi - resolution, we can use wavelet variance at different scales to weight and average the coefficients. thus either the difference in stability of different clock or the varying characteristic of the same clock at the different scale are all considered. finaly, this method is checked by the measured data from national timing serve center of shaanxi astronomy observatory. it confirmed that this technique, which is simple and practicable, is a new method of multi - resolution. from this method, the common characteristic of different clocks can be extracted. the stability of multi - resolution synthesis atomic time scale is obviously superior to that of other methods
本文根據小波分析的基本原理,對原子鐘信號進行多解析度分解,將分解后的小波變換系數進行加權平均,得到不同小波尺度綜合原子時的加權平均小波變換系數,然後由小波變換的重構條件,反演綜合時間尺度.由於對原子鐘信號進行了小波分解,利用不同尺度的小波變換系數的小波方差進行加權平均,這樣既考慮不同原子鐘在穩定性方面的差異,又顧及同一臺原子鐘在不同小波尺度的變化特性.最後根據陜西天文臺國家授時中心的實測數據對這種方法進行了檢驗.表明這是一種全新的多解析度綜合方法,這種方法比較簡單而切實可行,它能提取各個原子鐘的共同特性,多解析度綜合時間尺度的平穩性明顯優于其他方法Nevertheless, atomic clocks are accurate enough to record the shift and confirm that time really is stretched by motion
然而,原子鐘的精準度確實能記錄這個時間差,並驗證時間真的會因運動而拉長。Hko s network time service allows people especially those engaged in e - business to calibrate their computer clocks. the e - certification system of the hong kong post is also synchronized to the atomic clock of the hko. in 2002, on average 5 computers were connected to the hko s network time service every second
其他服務方面,天文臺利用網際網路提供香港標準時間,讓市民尤其是電子商貿參與者校正電腦時鐘,郵政署的電子認證系統也是以天文臺的原子鐘定時的,在2002年平均每秒有五部電腦到天文臺校對時鐘。Utc is a stable and even time scale based on the frequency of atomic oscillations in atomic clocks. this is the current international time scale for civil use
協調世界時是以原子鐘內的原子振動頻率為依據的時間標準,是十分穩定而且均勻的時標,亦是現時國際所採用的民用時間標準。Description of some of the expected future developments in time and frequency standards and distribution, including such topics as chip - scale atomic clocks ( size of a rice grain, powered by aa battery, potentially capable of low cost mass production )
介紹一些未來可預期的時間頻率標準和發布技術的進展,包括諸如「晶元級的原子鐘」 (大米粒尺寸,由aa電池供電,具有低成本大批量生產潛力) 。A utility to synchronize your system time with a reference clock is also provided. and you can uninstall your software
還具有讓系統時間和世界上的原子時鐘同步,軟體的反安裝等功能。分享友人
