style area width-
The conclusions are as follows : the ultrasonic intensity is proportion to the laser intensity ; the ultrasonic induced by a laser line source has much more advantages than by a laser point source, such as stronger energy, higher snr, more directivity and shape ; the intensity of cfpi ' s output signal is linear with ultrasonic vibration velocity, and is effected by incidence angle and scattered angle ; snr will increase by reducing cfpi ' s bandwidth, reducing incidence angle, increasing cavity ' s length and reflectivity
在分析點光源激勵聲表面波機理的基礎上，求出了線光源激勵的超聲振動的位移表達式，發現線光源激勵的近場區表面波具有波形好，信噪比高，指向性好，幅度強等特點。通過理論推導，得出共焦fabry - perot干涉儀的輸出光強除了與樣品表面的振動速度成正比，並與入射角和散射角有關；適當減小cfpi的帶寬，增加腔長，增大鏡面反射率，或者減小檢測入射角都可以提高系統的信噪比。Mode, the preferred width of a column is determined by resizing all columns in that mode so that all visible columns in the control exactly fill the horizontal width of the available display area
模式時，通過調整該模式中所有列的大小來確定一個列的首選寬度，這樣控制項中的所有可見列將準確填充可用顯示區域的水平寬度。68 quadrats were divided into 8 types of communities by twinspan, which can be treated as one - dimension resource states. the niche breadths and overlaps of main dominant species were measured using a series of indices proposed by levins, shannon - wiener and petraitis
在該地區植被的優勢種生態位的研究方面，仍然運用twinspan把樣方分為8個群落類型，用levins 、 shannon - wiener生態位寬度公式和petraitis生態位特定重疊指數公式測定群落中主要種群生態位寬度和生態位重疊，並分析各種群生態位的生態學意義。
