本研究擬對已知不同突出時間的腰椎間盤突出患者進行詢問病史、體格檢查和磁共振掃描，記錄臨床表現、突出時間、突出髓核及同層間盤的信號強度、突出髓核大小、突出間盤厚度、有無神經根受壓、有無黃韌帶肥厚、突出間盤變性程度、突出類型等指標，觀察突出時間不同的腰椎間盤的臨床表現及磁共振表現特點，尋找與腰椎間盤突出時間相關的指標，並根據臨床表現及磁共振所見初步判斷腰椎間盤突出的時間。 -
At present, signal pulses produced by directly modulated laser diodes have been used in optical fiber communication systems. the experiment reveals that the optical pulses from directly modulated laser diodes are far from gaussian and have near - rectangular temporal profiles with much sharper leading and trailing edges, and then a super - gaussian model, which assumes that an incident optical pulse has a super - gaussian profile, may be more suitable
但在實際的光通信系統中，人們常採用由直接調制半導體激光器產生的光脈沖作為信號脈沖，而實驗結果表明這種脈沖具有比高斯脈沖更為陡峭的前沿和后沿，其脈沖形狀更接近於超高斯分佈，並且通常還帶有一定量的啁啾。 -
The problem of doa ' s estimation of multiple source signals incident on a arbitrary array in the presence of both unknown spatially correlated noise and sensor errors is firstly considered. a modified ml estimation of doa ' s and sensor gain errors is presented. unlike previous work, the proposed method does not impose any structure constraints or parameterization of the signal and noise covariances. the algorithm can be carried out via the alternating projection approach. finally, the performance of the proposed method is shown with computer simulations as well as real array data

Two wedge interferometers are designed that the thickness of one is higher than the other. so when the incident coherent light through the interferometers can acquire two fringe patterns which having space shift, but the incident incoherent light only result in consistent intensity signal. through a differentiating amplifier, two signals subtract which can eliminate noise of background and result in higher contrast ratio fringe signals. this method largely improves the system and the ability of detection. the spacing of line fringes is a function of incident laser wavelength, by analyzing, we can extract the wavelength of incident laser. the optical unit analyzing and results also simulated with matlab
當背景光入射時，直接穿過干涉儀，僅發生強度的衰減，在兩個探測平面上產生幅度基本一致的灰度信號，通過差分放大器，相消為零，從而抑制了背景干擾。當激光信號入射，穿過干涉儀時受到調制，在探測平面上產生干涉條紋。通過所設計的存在平均厚度差的雙楔形干涉儀，兩路干涉條紋圖案出現相對移位：在兩個探測平面對應的位置上，一路出現亮紋，另一路出現暗紋。
