Thus, objective of this project is to improve the functionality and efficiency, and mitigate the drawbacks of a variable speed generation system or asg ( adjustable speed generator ) in conjunction with a dfig ( double fed induction generator ), which is frequently named as variable - speed / constant frequency ( vscf ) generation system
本文的研究目的是改進雙饋電機變速發電系統或變速驅動系統的的功能和效率，減輕系統缺陷所帶來的危害。雙饋電機變速發電系統通常又稱為變速恆頻發電系統（ vscf - variablespeedconstantfrequency ） 。 -
I ' ve assumed here that elsewhere in your driver is a manifest constant named mydevice _ alignment that equals a power of 2 and represents the required alignment of your device ' s data buffers
在這里我假設：在你的驅動的別的地方是一個明顯的叫做mydevice _ alignment的常量，它等價於2並且象徵你的設備的數據緩沖器請求的隊列。 -
Lao tzu said : " the way that can be spoken of is not the constant way ; the name that can be named is not the constant name
在道德經也是講同樣的道理。老子說：道可道，非常道名可名，非常名。 -
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。 -
A hybrid migration method, named " fourier finite - difference migration ", is a post - stack depth migration scheme. the downward extrapolation operator is split into three operators : one operator is a phase - shift operator for a chosen constant background velocity, another operator is the well - known first - order correction term, and the third operator is a finite - difference operator for the varying of the velocity function. phase - shift downward extrapolation and finite - difference downward extrapolation preserves the advantage of phase - shift method and finite - difference method
傅立葉有限差分（簡稱ffd ）偏移演算法是一種疊后深度偏移演算法，其向下延拓運算元是一種混合運算元，包括三項：一項是處理常速的相移運算元，一項是一階相移修正運算元，最後一項是類似45度方程的有限差分運算元，用來處理劇烈橫向變速。 -
The distribution and structure of the allelic polymorphism data are analyzed and it is pointed out that the distribution of allelic polymorphism data reveals the characteristic of closed data ( also named as compositional data or data of constant sum ) it is interpreted that the correlation structure of the allelic polymorphism data contains null correlations introduced by " closure " and the statistical distribution of the data is not normal because of its constant row sum, which resulted in great difficulties in analyzing the data with traditional multiple linear statistical methods such as principal component analysis, factor analysis, cluster analysis and canonical correlation analysis
摘要長期以來，對于多維基因多態性數據的多元統計分析，如計算遺傳距離時所用的聚類分析、分析群體遺傳結構時所用的主成分分析、因子分析和典型相關分析等，一直應用為無約束條件數據而設計的經典多元線性分析方法，並沒有注意基因多態性數據的「閉合效應」所帶來的問題。 -
But, in most of general risk model, the premium income is a constant rate, scholar have generalized the aggregated premium income from a constant rate process to a poisson process. in this article, the author defines the model that premium income is a compound poisson process, not a constant rate process, it is named compound poisson process premium income risk model
作者建立了保費收入為復合泊松過程的風險模型，在新的風險模型中包含兩個復合泊松過程，首先考察了復合泊松過程可加性的性質，據此性質，把這兩個復合泊松過程化簡為一個復合泊松過程，使模型得到化簡。 -
