傾斜極化 的英文怎麼說
中文拼音 [qīngxiéjíhuà]
傾斜極化
英文
inclined polarization-
However, when extremely high oblique impacts occurred ( 55 degrees or more ), as on turret roofs and decks, face - hardened armor, due to its brittleness, was a very poor choice since it could break and throw pieces into the region behind it even if the shell glanced off
然而當炮彈以極大的彈著傾斜角（ 55度或以上）擊中炮塔頂部和甲板時，由於裝甲的脆性，即便炮彈只是擦過，裝甲的背面也會破碎飛散，這時表面硬化裝甲便是個拙劣的選擇了。By computing the between two resolution units, we can estimate terrain azimuthal slopes and derive estimate of terrain elevation. the terrain contour is determined uniquely by ay / from azimuth slop on range gates. american began to study p - sar three - dimensional images technology in 1990s
Schuler已經證明，對於一個均勻分佈場景， sar圖像上兩個相鄰分辨單元的極化橢圓方向角偏移量，與地形方位向坡度的對應關系是線性唯一的，地形方位向的傾斜度可以通過解唯一地被測定。The government shall conduct innovation of system and mechanism, and urge our enterprises to go to the world : ( 1 ) to change the traditional concepts and strengthen the understanding of multinational operation ; ( 2 ) to improve the managing system of enterprises " overseas investing ; ( 3 ) to constitute and better the laws and regulations concerning external investing, ( 4 ) to strengthen information development and guide the multinational operation ; ( 5 ) to make policies in favor of giant enterprises, and help them go worldwide

文中先介紹了海雜波幅度的有關模型，通過對ipix雷達海雜波數據的i 、 q分量的直方圖以及傾斜度和峰度進行了分析和計算，證明了海雜波幅度不服從瑞利分佈;使用幅度直方圖和相同參數下的各種分佈模型進行比較，得出hh極化符合對數正態分佈，而vv極化服從k -分佈的結論;同時對海雜波的相關函數和功率譜進行了分析，最後使用sirp演算法產生了給定協方差矩陣的相關復合k -分佈隨機序列。Author thinks that the direction of the maximum plastic distortion along a constant radius around the crack tip may be considered as the direction of shear - mode fracture ( named pmax - criterion ) and the load when located shear band prongs the ligament in the front of crack tip is regarded as the limited load of shear - mode fracture. ( 3 ) the fad ( fracture assessment diagram ) of titled crack is proposed based on achievements of mesomechanics about i - ii complex ductile fracture of metal, and the titled crack is classified two kinds : void - mode fracture is assessed by fracture assessment curve, and shear - mode fracture by limited load. ( 4 ) using a fe program based on plantle - ressue theory to calculate some mesomechanical parameters, a flange joint structure of a high pressure vessel ( design pressure 31. 4mpa and the thickness of the hemispherical head is half of that of shell. ) is analyzed to determine whether the structure under operation pressure is safe or not, forecast the mode of potential invalidation and argue for the rationality of design of the structure
試件的整體斷裂為剪切型，但在試件芯部裂尖鈍化區中部出現了韌窩型啟裂並有一定的擴展，說明局部較高的應力三軸度也會使韌窩型機制得以發展，但是不改變試件整體的剪切型斷裂模式；對韌性斷裂的剪切模式的細觀機理做了一定的探討，並且提出了含裂紋構件剪切型斷裂的宏觀判據：認為裂紋前方的集中剪切帶中與裂紋尖端等半徑處最大有效塑性應變出現的方向可以作為裂紋剪切斷裂的方向（可簡稱為_ （ pmax ）準則） ，集中剪切滑移帶貫穿裂紋前方承載韌帶時的載荷可以作為極限載荷；本文運用金屬韌性斷裂細觀力學在一復合型韌性斷裂方面的研究成果，採用失效評定圖的形式，提出了傾斜裂紋的安全性評定方法的基本框架。The article relates that the tool ' s measurement precision has been improved by applying cycling acquisition method, self calibration function and phase - sensitive detector. the image coverage rate is improved and reached to 60 percent by increasing the number of pad ' s buttons. the tool carried out two logging functions : fast - scanner mode and dip mode
本文敘述了採用循環採集法、自刻度功能、相敏檢波等方法提高了儀器的測量精度；通過增加極板電扣的數量將圖像覆蓋率提高到60 ；實現了快掃描、傾角兩種測井模式；將測斜短節與預處理短節合二為一，縮短了儀器長度；去除了零伺服控制系統，簡化了電路；用fpga晶元對採集控制器重新設計。This was much less likely with soft homogeneous armor that could dent and tear slowly, easing the shell away and staying more intact, with few pieces torn off
然而當炮彈以極大的彈著傾斜角（ 55度或以上）擊中炮塔頂部和甲板時，由於裝甲的脆性，即便炮彈只是擦過，裝甲的背面也會破碎飛散，這時表面硬化裝甲便是個拙劣的選擇了。The main contributions of the dissertation are as following : ( 1 ) according to the theories of co - polarization and cross - polarization scattered characteristics, co - polarization and cross - polarization scattering characteristics of typical targets have been analyzed detailedly in this paper. a mechanism is described that rough surface tilted ( symmetrical distribution scene ) conduces to estimate terrain slope. so, we can estimate an elevation outline of symmetrical distribution scene without any experiential knowledge
