  1. When measuring the magneto performance parameter ， we find that the instrument which use to measure voltage and current is still the simple voltmeter and amperemeter in the national standard ， and the form of wave that we observed is anomaly. based on the measure principles, it obviously ca n ' t be used to do quantitative analysis ； because the discharge process of ignition system is quite complex, accompanies with very strong electromagnetism interference, and the ignition current and voltage are variable ， it make the measure of ignition energy become a difficult thing of ignition system performance detection

    在磁電機常規測量時，發現在國家標準中用於測量電壓、電流的儀器仍然是普通的電壓、電流表，而觀測到的波形多為不規則的形狀，根據測量原理，顯然不能用其來做定量的分析；由於點火系統的放電過程比較復雜，伴隨著很強的電磁干擾，點火電流、點火電壓都是變量，使得點火能量的測量成為點火系統性能測試的一個難點。
  2. And understanding and studying the spectral features and variation rules of geo - targets in the experimental area, raising that it is the basis of geo - targets information collection with imaging spectrometer data to understand spectral features and variation rules of geo - targets, realizing that in a great extent spectral - integrated - form - based classification method can remove the phenomenon of " different spectrum with same objects " resulted from reflection ratio curve translation because of the angle change among sensor, targets and observation direction, and the average and variance images can be introduced to solve the problem of two kinds of geo - target with similar spectral forms and much different values of whole reflection ratio. it is suggested that " red edge " range bands of vegetation, which has close relationship with vegetation cover and biomass, is the main characteristic bands and important basis for careful vegetation classification and quantitative retrieval, and pixel - based derivative spectral analysis is very useful for removing the effects of soil background values and quantitatively retrieving vegetation biomass and cover. the remote sense quantitative retrieval model is developed for main appraisable factors of desertification monitoring assessment with imaging spectrometer data and then the applicability of model is analyzed

    研究結果如下：首先針對荒漠化地區的地物特徵，對高光譜數據不同波段的數據質量、波段組合進行了評價，提出了適用於荒漠化監測的基本波段選擇集；初步了解和掌握了研究地區的地物光譜特性及變異規律，進一步明確了掌握地物光譜特徵和變異規律是用成像光譜儀數據提取地物信息的基礎；發現了基於光譜整體形狀的分類方法在很大程度上能夠消除由於傳感器、地物目標觀測方向之間的角度變化引起的反射率曲線整體平移的「同物異譜」現象，對于譜形相似而整體反射率的值相差較大的兩類地物，通過引入均值和方差圖像參與分類得到解決；研究還表明在植被「紅邊」范圍內的波段是進行荒漠化監測的主要特徵波段，這些波段與植被生物量和蓋度都有密切的關系，是開展精細植被分類研究和植被定量反演的重要基礎；像元的導數光譜分析可以消除土壤背景的影響，是進行植被生物量和蓋度定量反演的有力工具；建立了荒漠化監測主要評價因子的定量反演模型，並分析了模型的適用性。
  3. At present time, the infrasound method stays the stage of using recorders to record the infrasound wave continuously for 24 hours. automatically data acquisition and computerized analysis is not available

    目前次聲波採用記錄儀連續24小時觀測記錄其波形，還未實現數據的自動採集，所以無法利用計算機對信號進行分析處理。
  4. In the present dissertation, friction - induced noises emitted by a flat specimen rubbing against another flat specimen or a ball specimen under reciprocating sliding are studied. the detailed observation of the scars is conducted by means of a scanning electrical microscope ( sem ), laser scanning microscope ( lsm ), optical microscope and profilometer. the dynamic state variables are analyzed in detail using the discrete wavelet transform

    使用電子掃描顯微鏡（ sem ） 、激光掃描顯微鏡（ lsm ） 、光學顯微鏡和表面輪廓測量儀等設備對摩擦噪聲發生的區域進行了詳細的觀察和分析，運用小波變換技術對摩擦噪聲狀態下的動力學變量進行了深層次的研究，應用matlab simulink語言對摩擦系統進行了振動動力學模擬，系統地研究了摩擦噪聲的形成機理。
  5. In the first part, the basic knowledge of particle scattering in meteorology and physics was introduced. the particles to be discussed include aerosol particles, fog droplets and raindrops and the em wave band in the discussion is near - infrared. in the second part, the mie theory was briefly reviewed and was applied to investigate the scattering characteristics of spherical atmospheric particles, the result shows that in the visibility measurement meter using forward - scattering method, when the working wavelegth is between 0. 8 m ~ 2 m, the scattering angle is between 25 ~ 40, the distinguishability and the relative scattering intensity would be better than those under other conditions. in the third part, the superellipsoid was used to describe a wide range of shapes such as spheres. ellipsoids and cylinders. an improved t - matrix method which can be used to calculate arbitry shaped particle ' s scattering field was introduced, and the scattering characteristics of non - spherical atmospheric particles was investigated with this method

    計算結果表明，從相對散射強度、同一方向上不同粒子散射的可區分程度來看，在散射式能見度探測儀器中，工作波長介於0 . 86 m 2 m ，探測角度選取前向25度40度時，探測的結果將會是比較理想的。第三部分中，使用超橢球方程來統一描述各種非球形粒子的形狀，然後使用t矩陣方法計算了一些形狀的非球形粒子的近紅外散射特性。另外，在本文中還針對球形粒子的散射場提供了一種三維可視化方法，使對散射場強度的空間分佈的理解更加簡單，直觀。
