An on - line minimum - variance estimator was developed for thrust acceleration applied to orbit transfer using discrete - time radar measurements. the mass - flow - rate of propellant was selected as a state variant, which was estimated by employing an integral state model and ekf filter. the variation equations for measurement vector to mass - flow - rate have been established to linearize the discrete - time measurement equations. the algorithm has applied successfully to maneuver process in commanding satellite into geo - stationary orbit. the results show that the algorithm developed here can monitor and determine whether engine works well or failure precisely and quickly during orbit transfer process
飛行器軌道機動過程中，為跟蹤、定位機動目標和干預機動控制過程，需要統計處理離散的雷達觀測量實時估計推進發動機的推力，進而確定飛行器的瞬時軌道參數.本文所述演算法是該工程問題的探討和解決方案.文章建立了軌道機動過程中連續變質量運動模型和離散雷達量測模型，推進發動機的質量秒耗量作為表徵推力加速度的一個近似常量，應用擴展卡爾曼濾波對離散的雷達測量數據進行順序統計處理給出秒耗量的最小方差估計;文章詳細地推導了線性化量測模型的變分方程和觀測矩陣;模擬結果表明該演算法能快速、準確地估計推進發動機的質量秒耗量和向機動目標施加的實際推力 -
Methods by defining defaulting as a failure event and time from treatment starting to defaulting as survival time, we applied survival analysis technique with a real data to estimate a so called adherent rate and a median adherent time for evaluation of treatment adherence for patients with tuberculosis
方法將退出療程作為所關心的結局事件，將從登記治療開始到退出療程的時間作為堅持治療時間，利用生存分析統計技術估計堅持治療率和中位堅持治療時間以評價結核病患者的治療依從性。 -
Liver diseases, for example, hepatitis and cirrhosis, which finally lead to liver function failure ( lff ), have a high incidence rate in china. now we still face with great challenge to how to treat them. although liver transplantation is generally accepted as the first selection for the treatment of lff, it is not extensively applied because of deficiency of donor and immunological rejection after transplantation
肝臟疾病（如肝炎、肝硬化）在我國具有很高的發病率，這些疾病最終導致肝功能衰竭，如何治療肝功能衰竭目前仍然是肝病臨床的一大難題，雖然現在公認的最好的治療方式是肝移植，但是由於受到供體來源缺少的限制和移植后的免疫排斥反應，而不能廣泛應用。
