For high stability of the system, with the realization of hardware of the system, the second part of this paper starts from the transmission line theory, and studies the signal integrity problem of high - speed circuit system in light current. the causes of these signal integrity problems, such as signal delay, reflection, crosstalk, ground bounce noises and etc. are analyzed in theory. combined with actual design, key points of design and standard design flow of general high - speed, high - precision printed circuit board are summarized, which has been applied in actual system, and good effect has been achieved
為使系統具有較高的穩定性，本文第二部分結合該處理器的硬體實現，從傳輸線理論出發，研究了弱電情況下高速電路印刷電路板中的信號完整性問題；從理論上分析了延遲、反射、串擾以及地彈噪聲等信號完整性問題產生的原因；結合實際設計，總結了一般高速、高精度印刷電路板的設計要點和標準設計流程，並在實際系統中獲得了應用，取得了很好的效果。 -
Relativity says that light always moves in a straight line through empty space, and always at the same speed in a vacuum, no matter what your observation point
它指出光在真空中走直線，且在真空中光速恆定，不論你的觀測點如何。 -
Transit and rail industries in many nations have already adopted the digital system as their regular radio communications system. in asia for example, the digital trunked radio system has already been adopted for system expansion or replacement by several organizations. these include the transit northeast line in singapore 1991, the mass transit system smrt in singapore 1998, the high speed railway in malaysia 2000, the guang - zhou subway in china 2000, the west line of guang - jiu railway in china 2000, the peking light railway in china 2001, and the new delhi transit system in india 2001
據了解現在各國新建捷運路網無線電系統規劃方式，有往數位干線式無線電系統發展之趨勢，並且已成各國捷運及鐵道工業無線電通信的主流標準，以亞洲為例：新加坡捷運東北線（ 1998年） 、新加坡高運量捷運smrt （ 1998年） 、馬來西亞快速鐵路（ 2000年） 、中國廣州地鐵（ 2000年） 、中國廣九鐵路西線（ 2000年） 、印度德里捷運（ 2001年） 、中國北京輕軌系統（ 2001年） .均已於系統擴建或新建時規劃採用數位干線式無線電系統。 -
But your friend also sees you getting heavier, in fact infinitely heavy as you approach the speed of light relative to the starting line, so you would need an infinite amount of rocket fuel to get up to light speed with respect to your friend
但你的朋友也會看到你變得越來越重，實際上當你無限接近光速時你也將變得無限重，因此你會需要無限的火箭燃油來使自己接近光速（相對於你的朋友） 。 -
Laser - scanned on - line inspection system ( lois ) involving laser, optics, electronics, fine mechanics, opto - electronic transformation and computer etc, is used to realize high speed and accuracy, non - contact and on - line inspection for rotating body types of parts, in the system, a visible laser is taken as its light source, the geometric parameter of the measured object is transformed into the electrical signals by a scanning optical system and an opto - electronic transformation system, the measured result is given and displayed by the computer real - time data processing
激光掃描在線檢測系統是一種基於激光技術、光學、電子學、精密機械、光電傳感技術及計算機等多學科技術於一體的高精度、高速度、非接觸在線檢測系統。它是用可見激光作為光源，把被測對象的幾何尺寸經過掃描光學系統和光電變換系統轉變成電信號，再由計算機進行實時數據處理。給出測量結果，並數字顯示。
