Multiple comparison method and similarity coefficient method were developed to estimate population size of the giant panda. the chi - square testing was used to determine the relationship between the occurrence of pandas and the type and intensity of human disturbance. habitat selection of the giant panda and impacts of human disturbance, such as logging, livestock grazing, herb collecting, poaching, road building, were quantitatively analysed by habitat selection index of manly
同時還利用manly （ 1993 ）的選擇指數（ selectionindex ） ，定量分析王朗大熊貓對生物和非生物生境因子的選擇，特別是分析如採伐、放牧、采藥、偷獵、修路等人類干擾對大熊貓及其生境的影響，從而為保護區大熊貓的管理提供依據，將造成大熊貓瀕危的人類干擾降至最低。 -
The method that increases the attitude accuracy of strapdown inertial attitude and heading reference system ( siahrs ) with the infromation from inertial measurement unit ( imu ) its own is studied. according to the design idea of damping network in platform type, damping kalman filter in siahrs is designed to enhance the attitude accuracy via integrating attitude calculated by common siahrs and that estimated by accelerometers. in order to evaluate the effectiveness of damping attitude, the vehicle ' s movement should be detected in real - time. for this reason, the state chi - square test is employed in the damping kalman filter, and the failure detection vector are tested, which improves the sensitivity and reliability of failure detection. finally, static and dynamic experiments of actual system demonstrate the effectiveness of the proposed method
本文探討了如何利用慣性測量組合本身的信息來提高捷聯航姿系統的姿態精度.根據平臺式阻尼網路的思想，設計了捷聯式內阻尼卡爾曼濾波器，將慣導系統捷聯解算獲得的姿態與加速度計估計的姿態進行組合，在系統非加速度狀態下，提高了姿態輸出的精度.為了實時監測系統的運動狀態從而判斷內阻尼姿態的有效性，本文成功將狀態2檢驗法應用在內阻尼卡爾曼濾波器中，設計了基於2個狀態傳播器的故障監測器，並通過對故障檢測向量元素的檢驗代替對整個向量的檢驗，提高了故障監測的靈敏度和可靠性.最後，實際系統的動靜態實驗驗證了本文所提出的方法的有效性 -

Based on the theory and knowledge, the paper proposes and discusses several robust detectors in detail, such as optimal periodical signal detectors which exploits the prior knowledge that the chi _ square distribution hypothesis test has certain robustness, detectors based on over _ sampled gabor representation for transient signals detection which takes the numerical computational advantage of robustness brought by over _ sampling, and the detector using computer _ intensive method " bootstrap "
在此基礎上，詳細討論幾種具有一定robustness的檢測器，即，基於具有robustness的卡平方假設檢驗的周期信號檢測方法、利用過采樣的gabor表示的暫態信號檢測方法以及基於計算機強大計算功能的統計學方法bootstrap技術。
