砷化鎵探測器This paper reviewed new progress of biosensor applying to environmental monitoring, including detection of arsenide, sulphide, insecticide and herbicide ' s remains, on - line monitoring of wastewater quality, measurement of bod and ammonia nitrogen, detection of phenol and odorous compounds, as well as monitoring of air and exhaust gas
摘要綜述生物傳感器應用於環境監測的最新進展，包括對砷化物、硫化物和殺蟲劑及除草劑殘留物的檢測，對廢水水質的在線監側，對bod和氨氮的測定，對酚類和有氣味的化合物的檢測以及對大氣和廢氣的監測等方面。After measuring dark current, photocurrent and response to x pulse of gaas detector before and after 1. 7 mev electronic radiation, the response tune, fall time of trailing edge, full width of half maximum ( fwhm ), sensitivity, carrier life, mobility are researched and contrasted. the result shows that the response speed of detector, time resolution ratio and nonlinear of back edge of output signal have been improved greatly after electronic radiation. though sensitivity of the detector reduces, its measuring range can be widened
為了使探測器的性能得到進一步的提高，我們對其進行了電子輻照改性，並測量了本徵砷化鎵探測器和經過1 . 7mev電子輻照的探測器的暗電流、光電流及對x射線的脈沖響應，並對其響應時間，后沿下降時間，半高寬（ fwhm ） ，載流子壽命，靈敏度進行對比，研究，結果顯示經電子輻照后的探測器的性能得到了改善，使響應速度，分辯率進一步提高，並消除了探測器輸出信號后沿的非線性，雖靈敏度有所降低，反而使其測量范圍得以拓寬。Arsenic determination apparatus
