中文拼音 [xīngxìbàng]
星系棒
英文
galactic bar-
Ringed barred spiral galaxy
有環棒旋星系Barred spiral galaxy
棒旋星系Bars are hard to recognize in distant galaxies
遙遠星系中，比較難辨識出棒狀結構。Ringed barred galaxy
有環棒旋星系An adaptive robust control system of mobile satellite antennas is presented
首先針對移動衛星天線數學模型，設計自適應魯棒控制器和控制系統。Most people think of our own galaxy, the milky way, as a pure spiral, but astronomers now know it is actually a barred spiral
大多數的人認為我們自身的銀河系是個單純的螺旋星系，但天文學家現在知道它其實是個棒旋星系。Robust control of a class of switched systems
衛星姿態跟蹤系統的魯棒控制器設計During this time, the bar prevents fresh gas from entering the central part of the galaxy
在這段時間里，星棒阻止了新鮮氣體進入星系的中心地帶。To simultaneously solve the problems of the robustness, decoupling control and high accuracy tracking control at the high tracking rate in antenna control system, a new nonlinear antenna tracking - pointing control system for user - satellite was proposed based on a unique nonlinear active disturbance rejection control method
摘要為同時解決用戶衛星天線控制系統的魯棒性、解耦控制和高跟蹤速率下的高精度跟蹤控制等問題，採用非線性自抗擾控制方法，提出了一種新型的用戶衛星天線跟蹤指向控制系統。And in the most detailed analysis yet, astronomers say a long bar of stars cuts on an angle through the center of the milky way galaxy
根據至今為止最詳盡的分析資料，天文學家們認為存在著一個恆星棒，它與銀河系中心連線形成一個夾角Ironically, by pulling matter into the core of a galaxy, a bar can destroy itself
諷刺的是，把物質拉進星系核會造成星棒自我毀滅。The results given by the improved software are not both statistically and biologically different from manually specified results, and thus can be used as an effective alternative for the latter. it has a very high sensitivity in determining cells with a tail, meeting the needs of screening tests. it has both a high sensitivity and a high specificity in determining cells with 2 damage grade, indicating a potentially good laboratory index
結論彗星試驗圖像分析軟體經改進后，分析準確性得到提高，程序魯棒性增強，而且易用性改善，並增加了由操作者進行必要校正的功能;所得分析結果與人為指定的分析結果相比，並不同時存在統計學顯著差異和生物學顯著差異，可作為真實可靠的彗星數據分析系統應用;改進后的系統在拖尾細胞判定上具有很高靈敏度，可用於篩查試驗項目;在2級及2級以上損傷細胞的判定上同時具有較高的靈敏度和特異度，是實驗室研究中的優良指標。The accumulated mass scatters stars and prevents them from orbiting regularly, as a bar requires
累積的質量造成恆星分散，不讓它們規律地繞轉，而這是維系棒狀結構的必要條件。Spirals are sub - divided into two classes : the normal spiral and the barred spiral
旋渦星系可細分為兩種：普通的旋渦星系和棒旋星系。But if so, what accounts for the large number of barred galaxies that astronomers see
若果真如此，該如何解釋天文學家觀測到的大量棒旋星系呢？The bulge of the barred spiral is elongated like a bar, thus given the name. the galaxy above is m31, a normal spiral only 2, 000, 000 ly away. photo below shows a barred spiral
上圖為m31仙女座大星系，它是一個普通的旋渦星系，距離地球只有二百萬光年，下圖的是一個棒旋星系。In visible images, two thirds of galaxies have bars, and near - infrared surveys in 2002 raised the estimate to three quarters
在可見光的影像里， 2 / 3的星系帶有棒子，這個數量在2002年所做的近紅外光巡天中達到3 / 4 。Theorists could not find a way to avoid bar formation ? and thereby explain the galaxies that lack such a structure ? without contradicting other observations
在不?觸其他觀測的結論下，理論學家無法找到避免形成棒子的方式，因此不能解釋缺乏棒狀結構的星系。分享友人
