二次微分 meaning in Chinese
quadratic differential
second differentiation
Examples
- Bifurcation problem of a quadratic differential system with distribution of lc ' s
分布的二次微分系统的分支问题 - On the reflective function and the periodic solution of the second order differential quadratic systems
二次微分系统的反射函数及其周期解 - By using the method of qualitative analysis , phase portraits for a class of quadratic differential system are investigated . nine phase portraits are found and shown for this system
用定性理论方法研究了一类二次微分系统的相图,得出该类系统的相图共有9种,并且给出了这9种相图 - There are many existing algorithms that solve the maximin or minimax programming without constraint or with linear constraints . some of the algorithms need the 2nd order differential information of objective functions
人们已提出了一些求解maximin (或minimax )规划的算法，这些算法要求规划问题无约束或具有线性约束，以及要求有关函数的二次微分信息 - From absorption spectra and the second - order derivative spectra , three absorption speaks of excitons were clearly resolved . at the same time , the first exciton absorption peak got stronger with decreasing nanocrystals size . blue shifts due to quantum confinement were observed obviously
纳晶吸收谱及二次微分谱的测量结果表明，纳晶在室温出现了三个激子吸收峰，第一激子吸收峰随纳晶半径减小而增强，同时清楚地观察到纳晶受限导致的光谱蓝移。
