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

發現： （ 1 ）在考慮doppler展寬的情況下，通過選取合適的實驗室條件（比如合適的原子環境溫度等）可得到合適doppler展寬值，從而使系統獲得最佳增益； （ 2 ）要想實現系統的頻率上轉換，同時又要獲得足夠強的無反轉激光增益，則系統頻率轉換比不能選取的太大； （ 3 ）對于開放系統，比較小的粒子注入速率比與退出速率對產生無反轉激光是有利碩士學位論文摘要的： （ 4 ）由於dopp1oy展寬的存在，當探測場與驅動場的傳播方向相反時，增益在探測場失諧的某一段區域產生振蕩，且振蕩的振幅、頻率失諧范圍的大小與dopper展寬的取值有關。The writer passes the fixed amount and qualitative analysis, the actuality investigates and theories study combines together, thinking that the main key stiching point of the high school grammar teaching consists in : the target of the high school grammar teaching escapes from the education of the large teachers and students with learning the real fact ; the high school grammar content system originates the result in studying the grammar, but many abuses exsisr hi the grammar research, thus affect the high school grammar teaching directly or indirectly ; in the cognition of the high school grammar teaching, people also need a process for continuously inclining to science ; the limitations of the contents and arrangement also exist in the grammar teaching materials - high school grammar teaching materials that arrange according to the grammar system oneself have the limitations, the contents of the language grammar in the teaching material and arrangement also have certain limitations, such as do n ' t follow the students " regulation of cognition, there is no the contents of the grammar teaching in senior high school and the request, the grammar in junior high school does n ' t pass, in the senior high school then returns to living, gradually, etc ; furthermore, teacher ' s character and the teaching methods are n ' t well suited, do n ' t join the static grammar teaching with the dynamic grammar teaching, neglect the practical characteristics of the teaching grammar ; for a long time, the position of the meaning in the grammar teaching of the high school is n ' t fixed correctly, either higher or lower etc. from here, the writer gets a conclusion : because of the existence of the above problems, cause " grammar useless " then request " desalinate grammar " even " cancel the grammar " creation, but not grammar knowledge oneselt is useless, therefore, from now on the direction of the grammar reform in education is to resolve these problems, not desa linate and cancel
在1898年馬建忠撰寫的第一部漢語語法專著《馬氏文通》問世到現在的一百多年裡，語法教學在中學語文學科中的地位始終沒有確定下來， 「淡化」甚至「取消」語法教學的觀點時而浮現于語文教學的理論與實踐中。問題的癥結何在?筆者通過定量與定性分析，現實調查與理論探討相結合，認為中學語法教學的主要癥結在於：中學語法教學確立的目標脫離廣大師生的教情與學情實際；中學語法內容體系來源於語法研究成果，而語法研究中存在著諸多弊端，從而直接或間接地影響著中學語法教學；人們對中學語法教學目的的認識也有一個不斷趨向科學的過程：語法教材也存在著內容及編排的局限性? ?中學語法教材的依據語法體系本身具有局限性，語文教材中的語法的內容與編排也具有一定的局限性，諸如沒有遵循學生的認識規律，高中沒有語法教學的內容和要求，語法初中沒有過關，高中則更趨回生等；再者，教師素質及教學方法不適應，沒有把靜態的語法教學與動態的語法教學結合起來，忽視了教學語法的實用性的特點；長期以來，中學語法教學的意義定位不準，不是偏高就是偏低等等，由此，筆者得出結論：由於上述問題的存在，導致了「語法無用」進而要求「淡化語法」甚至「取消語法」論調的產生，而並非語法知識本身無用，因此，今後語法教學改革的方向是解決這些問題，而不是淡化和取消。The main work of the thesis is as follows : we design a novel omni - mirror more applicable in robocup, which is made up of an isomeric horizontal mirror and an isomeric vertical mirror and can make the resolution of the imaging of the objects near the robot on the field constant and make the distortion of the imaging of the objects far from the robot small in vertical direction ; we select a 1394 digital color camera and complete the development of its software program for data acquisition ; we design a image processing algorithm for the panoramic image, which can segment the image by color, extract the features of image fast and effectively and complete the recognization of target ; according the character of the imaging, we design a new fast hough transform algorithm for line detection, which can detect the white mark lines of the field realtimely, and then design a robot ’ s self - localization method based the mark lines, which only uses the information of omni - vision system ; finally we design a monte carlo localization method based on the information of omni - vision system and odometry, and present the localization results of two localization methods and analyze the experiment results and get the conclusions
