  1. To ensure the security of gi inspection, no approving method has been developed by far to drive the capsule endoscope but utilizing the natural peristalsis of gi tract. the uncontrollability of the capsule endoscope brings on some limitations in its functional extension in inspection, medication and surgery, such as temperature and ph measuring, medicament spraying, sampling, on - line sample analyzing, laser incising and rf cauterizing

    膠囊內窺鏡目前還沒有實用的主動驅動方法,只能利用消化道自然蠕動作為膠囊內窺鏡前進的動力。由於膠囊內窺鏡不可控,限制了它的功能擴展,比如壓縮空氣噴藥、吸取組織樣品、在線樣品分析、激光切割、射頻燒灼等。完善的膠囊內窺鏡系統需要在現有基礎上加入安全有效的驅動控制,可調整姿態、行進及定位,從而擴大膠囊內鏡檢查的適應癥、安全性與多功能性。

    本文先介紹了當代無線電導航的狀況以及發展趨勢和無線電的傳播,然後對接收機射頻前端的關鍵技術指標進行了深入分析,還介紹了系統在大動態范圍,高線性實現的一些設計方法,之後詳述了本項目採用的方案、具體功能指標的實現以及在設計與實現中應該注意的問題,最後給出系統的測試結果。
  3. Plasma characteristics of a rf ion source are investigated by emission spectroscopy. the spatiotemporal spectral line intensities of the first three atomic lines in hydrogen bahner series ( = 656. 28, 486. 13, 434. 05nm ) of rf ion source plasma, are measured with calibrated optical multichannel analyzer ( oma ). some plasma parameters, including electron temperature, hydrogen atom density and hydrogen ion density, are calculated and analyzed using partial local thermodynamic equilibrium ( plte ) theory and abel transform

    實驗採用絕對定標后的光學多道分析系統( oma )測定了離子源等離子體不同時間和空間位置的氫原子巴耳末譜線系中前三條譜線( = 656 . 28 , 486 . 13 , 434 . 05nm )的強度,並採用plte的理論和abel變換方法,計算出了高頻離子源等離子體的電子溫度、氫原子濃度、氫離子濃度等參數在放電的不同階段和徑向分佈情況,並進行了簡要分析。
  4. For recent years, adsl has world widely employed and widely used in many aspects such as vod, remote medical treatment and e - shopping etc. but we noticed that the traditional telephone networks are designed for the transmission of low frequency signals, and the adsl ' s frequency rang is from 0 to 1. 104mhz, so we must confront the signal attenuation, the loop line noise impairments, the crosstalk interferences, the bridge tap reflections and the rf disturbances problems and many other problems when transmitting the adsl signals one the telephone networks

    近幾年來, adsl在世界范圍內得到充分的使用,廣泛應用於視頻點播、遠程醫療、網上購物等各個方面。但是由於電話線網路是專門為傳輸低頻信號而設計,而adsl的頻譜范圍在0 1 . 104mhz內,因此在傳輸adsl信號時,面臨著信號衰減、線路噪聲、串音干擾、橋接抽頭反射和射頻干擾等等多方面的問題,這就要求在adsl開通之前對線路進行一系列的測試。
  5.
