divergent series 中文意思是什麼
divergent series
解釋
【數學】發散級數。-
Definition the infinite series converges and has sum if the sequence of partial sums converges to, that is. if diverges, then the series diverges. a divergent series has no sum
定義如果級數的部分和數列有極限，即，則稱無窮級數收斂，這時極限叫做這級數的和，並寫成；如果沒有極限，則稱無窮級數發散。 -
Damage stability curves of a series of damaged one - compartment respectively and combinations of damaged multi - compartments are needed in probabilistic method. systems of equation of floatation and stability may be divergent when damaged multi - compartments are calculated that may lead to programs stop. the reason is studied and that makes the programs can distinguish this case and eventurelly the probabilistic calculation of arbitrary damaged multi - compartments is carried out
在概率方法中，需要計算一系列的破艙組合下船舶的穩性曲線，由一艙破損、相鄰兩艙破損到相鄰三艙破損再到相鄰四艙破損等，由於這種破艙組合是由程序來實現的，多艙組合破損時計算過程中浮態與穩性的計算可能異常而導致程序中斷。 -
So it is available to reconstruct moderate and large image by using either parallel or divergent projection data, as well as the data collected at series arbitrary sampled angles and sampled radii. and it does not require the storage of projection matrix, compared with the conventional art. the numerical results show that mart reconstructs image with fast speed, high resolution and sligh artifacts
利用分塊迭代的快速art方法，對x射線工業ct實采投影數據進行圖像重建，並與fbp方法、經典art方法重建的圖像進行了比較，測試結果表明：該方法重建圖像精度高，偽影輕，並有較高的密度解析度和空間解析度，較經典art方法重建速度快。 -
Theorem 1 ( abel theorem ) if the power series is convergent at, then for any that, the power series absolutely converges at point ; if the power series is divergent at, then for any that, the power series diverges at point
定理1 （阿貝爾定理）如果級數當時收斂，則適當不等式的一切使這冪級數絕對收斂；反之，如果級數當時發散，則適合不等式的一切使這冪級數發散。
