  1. The test samples injected into injection valve are brought into the column by mobile phase ; all ingredients are separated in the column and entered into the tester by order, chromatographic signals of which will be recorded by recorder, integrator or data processing system

    注入進樣閥的供試品，由流動相帶入柱內，各成分在柱內被分離，並依次進入檢測器，由記錄儀、積分儀或數據處理系統記錄色譜信號。
  2. This paper gives a time - synchronization technique bases on gps time service signal which is used in broad band seismic recorder 。 by world coordination time offered by gps - - utc ( usno ), adjust local clock base on gps signal, gain high nicety clock signal, clock precision reachs 10 - 6 。 this clock is the time source of broad band seismic recorder, bring the whole seismic recorder works in same time base. 1pps time base with high stability can be used as in - phase, spring, time and start - stop of every collection mode, while the scale under second make a precise time mark to receive data of broad band seismic recorder

    針對接收機中gps信號的噪聲進行kalman濾波軟體處理， kalman濾波可以對gps信號與本地晶振時鐘的時差數據在大噪聲中進行平滑，在較短時間內估計出高精度的時差數據。系統消除了gps秒脈沖信號的ms級隨機誤差，把晶振秒脈沖的長期穩定度鎖定到gps信號的穩定度上;在gps信號失效時給出了可行措施，能夠保證在任何情況下產生一個穩定、高精度秒脈沖信號，誤差在1 s內。
