根據國際天文學聯會international astronomical union於2006年8月24日通過的行星定義,冥王星的行星資格被取消,並被界定為一類稱為矮行星的新天體。In agriculture, the " da yue jin " movement includes the great upsurge in production construction, the form implements innovation, the deep ploughing and intensive cultivation, the boast of high yield and the origin of the people ' s commun. in industry, the " da yue jin " movement emphasizes the importance of steal and iron, which requires all the people participate in the stealmaking activity enthusiastically and the collection of disposed steal and iron. in education, the " da yue jin " movement consists of the illiteracy elimination, the combination of study and work, the promotion of the sparetime education and the education reform
本文首先論述了「大躍進」運動前夕國際國內以及西安市的形勢,接著主要從群眾性的生產建設熱潮、農具改革、深耕密植、大放高產衛星以及人民公社的誕生等方面詳述了西安市農業「大躍進」的情況;在工業「大躍進」中,則論述了鋼鐵元帥開帳、全民大煉鋼鐵運動、大力收集廢鋼鐵、勞動力的流動等問題;教育「大躍進」 ,則從大力開展掃盲、學習和生產勞動相結合、 「兩條腿走路」大辦業余教育、教學改革四方面展開論述;商業「大躍進」 ,是分別從學習天橋經驗、支授工農業「大躍進」 、技術革命等方面進行了闡述。Magma rose from the mantle forms new crust and slowly squeezes old one aside. since the earth s magnetic field alternates from north to south about every 10, 000 years, the iron - bearing minerals in the crust magnetize and " memorize " the direction of the prevailing magnetic field, just like a magnetic tape recording the geological evidence of aeon
國際天文學聯會international astronomical union由2001年起曾多次就行星的定義作出討論,最終聯會各與會者於2006年8月24日作出共識,定義行星planet為是一顆星體,需附合下面的三個條件:Now, a group of astronomers are petitioned against the new definition, so the story is not yet end
現在,一群天文學家正向國際天文聯會請願並要求重新定義行星,冥王星的故事和最終命運可說是仍未完結。Under proposed international astronomical union definitions, two planets that orbit each other around a barycenter between them are a binary planet
根據國際天文學會的定義提出兩個行星軌道周圍的重心在彼此之間是雙行星系統。According to iau, a " dwarf planet " should have an orbit around the sun
譯:國際天文學聯合會的意見認為, 「矮行星」應該繞太陽沿軌道運轉。The algorithm of strapdown inertial navigation system is also discussed and then use the flight - track generator to give a simulation, since a closed loop feedback integrated navigation system is designed in this paper, and the output of the filter must feed back to the strapdown inertial navigation system, the analysis of the algorithm in strapdown inertial navigation system is important. the scheme to design the trajectory of gps and the simulation of gps constellation are then studied, the simulation of gps constellation is given from the calculation of vernal equinox base on the principle of celestial mechanics, this method of different from other methods given by other paper and is useful to the research of satellite navigation system. a new method to abstract noise modal in integrated navigation system is proved to be useful in practice, this method, which is given by use the principles of stochastic processes, statistics, time series analysis, and system identification, is suitable for the kalman filter in integrated navigation system
如航跡產生器的設計,該航跡產生器是研究組合導航問題的前提,從國外一些研究組合導航系統的文獻中可以看出,設計這樣一個航跡產生器是非常必要的,所以本文自行設計了這樣一個系統;還討論了捷聯慣性導航系統中捷聯解算的方法,並進行了模擬研究,由於在本文設計的閉環反饋式組合導航系統中,對捷聯慣導系統的平臺誤差進行閉環控制,需要將濾波器輸出的校正量反饋到捷聯解算內部,所以必須對捷聯解算進行深入的研究和分析,更何況捷聯解算問題本身也是導航界的一個熱門研究課題;另外,本文還介紹了gps軌道及其星座模擬的設計思想和方案,與以往gps軌道和星座模擬不同的是本文從天體力學中計算春分點開始,逐步進行gps軌道及其星座模擬,這樣的設計方法對從事衛星導航的研究工作是有價值的;還對組合導航中誤差建模方法進行了研究,綜合運用隨機過程、概率統計、時序分析及系統辯識等方面的理論提出了一套適合組合導航卡爾曼濾波的誤差建模方法,並運用實際研究工作中的測量數據對該方法進行了驗證。Much - maligned pluto would remain a planet and its largest moon plus two other heavenly bodies would join earth ' s neighborhood under a draft resolution to be formally presented wednesday to the international astronomical union the arbiter of what is and is not a planet
