  1. ( 5 ) when hydrocarbon compound is coved by thick shale, hundreds meters low velocity gas incursion diffuse band is seen clearly above sandstone in huanhua sag. sometimes bulk and range of incursion diffuse band is large than hydrocarbon compound accumulate body. its seismic response must be recorded

    （ 5 ）研究發現，當烴類聚集體被厚層泥巖覆蓋，在其上方出現百米以上的低速氣浸擴散暈的現象，它對地震波場的附加影響必會被記錄下來，使對2500 4500米埋深含油氣砂巖的地震檢測成為可能。
  2. There are three power transistor which have been widely used in s band now : bipolar junction transistor ( bjt ), gaas metal - oxide semiconductor field effect transistor ( gaas mosfet ) and lateral diffuse metal - oxide semiconductor field effect transistor ( ldmos fet ). thanks to the advantages, such as, wide frequency, easy power supply, good stability, the ldmos fet has used in the motion telecommunication

    目前在s波段人們常用的放大器有雙極性晶體管（ bjt ） 、砷化鎵場效應晶體管（ gaasmosfet ） 、邊緣擴散場效應晶體管（ ldmosfet ）等，由於ldmosfet具有頻帶寬、供電方便、穩定可靠等優勢，目前已經廣泛用於移動通信3g的研究。
