| 2. | ( 2 ) a new method of overcoming the ill - condition - two - step method is proposed ( 2 )提出了一种克服病态性的新方法-两步解法。 |
| 3. | A nonmonotonic criterion is used to speed up the convergence progress in some ill - conditioned cases 既约hesse算法是目前较流行的解决非线性等式约束优化问题的有效方法之一。 |
| 4. | In this thesis , the origin , definition , and dependence of the solution - uniqueness of the inverse problem and ill - conditioning are discussed first 因此,本文首先从反问题的起源和定义入手,然后着重分析研究了反问题解答的适定性问题。 |
| 5. | The classic difference scheme of euler is employed to solve the forward problem , and the truncated singular value decomposition is used to solve the ill - conditioned system of algebraic equation 用古典欧拉差分格式求解正问题,用截断奇异值分解法求解病态方程组。 |
| 6. | For electrically large problems , the condition number of impendence matrix is very large , and furthermore , the ununiformity of the modeling leads to an ill - conditioned matrix 对大型电磁散射问题,不仅矩阵的条件数大,而且由于表面网格剖分的不均匀有可能产生病态的矩阵。 |
| 7. | Bath vibroflotation process and high - pressure sprinkling grouting are new construction technologies , which are good in techniques and cheap in economies , in dealing with ill - conditioned reservoirs 振冲法及高压喷射灌浆是土石坝加固中的两种新技术,具有良好的技术和经济性能。 |
| 8. | If the ill - conditioning is really existence in adjustment model , we must take measures to remove or weaken its influence in order to gain good precisions of parameters estimator and adjustment production 当确知测量平差模型存在病态性时,必须设法消除或减弱病态性的影响,以提高参数估计和平差成果的精度。 |
| 9. | Then , in the light of the characteristic , based on the tikhonov regularization theorem , two new regularizers are designed to mitigate the ill - condition of the normal matrix in gps rapid positioning 基于tikhonov正则化原理,针对这种特性,设计了两种正则化矩阵r的构造方法。通过新的正则化矩阵的作用,减弱了法矩阵的病态性。 |
