Although there have been some suggestions on how to ensure the positive definiteness of the iterative matrices , they are restrictive and is not easy to be implemented 尽管已有一些关于怎样保证迭代矩阵正定的讨论,然而还没有切实可行的方案。
I would never be so bold as to say i know the truth , said the mason , the definiteness and decision of whose manner of speaking impressed pierre more and more “我决不敢说,我洞悉真理, ”共济会员说,他以那明确而坚定的言词越来越使皮埃尔感到惊讶。
So analyzing chaos from the angle of linear theory and definiteness theory can not meet the increasing requirement to control performance of dc / dc converters 因此,仅仅从线性论和确定论的角度去分析混沌已不能满足对dc dc变换器控制性能日益提高的要求。
Chaos is a kind of seemingly random , chance or irregular movement , which appears in a definiteness system . it is a property token of non - linear system 混沌是发生在确定性系统中貌似随机的无规则或不规则运动,它是非线性系统的一种性能表征,在工程中有着广阔的应用前景。
Point , burning duskily through a veil of cloud ; but with no such shape as his guilty imagination gave it ; or , at least , with so little definiteness , that another s guilt might have seen another symbol in 这并非是说,当时根本没有流星出现并在云霭中隐隐燃烧而是说并没有他那负罪的想象力所赋予的那种形状或者,至少不是那么确定无疑别的罪人也可能从中看到另一种象征呢。
With that peculiar exactitude and definiteness , which is always employed in the examination of prisoners and is supposed to preclude all human weaknesses , they put questions to pierre and the others , asking who he was , where he had been , with what object , and so on 这些法国人对皮埃尔等人,用自以为可以超脱人类弱点的精确和肯定语气通常对待被告就是如此,问了:他是谁?到过哪里?有什么目的?
It gives a number of sufficient conditions on the subpositive definiteness of the matrix product of two subpositive definite matrices , and also provides some necessary and sufficient conditions on the subpositive definiteness of the matrix product of two special subpositive definite matrices 摘要主要给出了两个亚正定矩阵的乘积仍是亚正定矩阵的几个充分条件以及两个特殊的亚正定矩阵的乘积仍是亚正定矩阵的充要条件。
It comes nearer and nearer , and grows in clarity and definiteness of outline , until the form of the buddha can be seen , seated in the cross - legged buddha position , clad in his saffron - colored robe , bathed in light and color , and with his hand extended in blessing 它变得越来越近,很明显地增大,形成了轮廓,直到可以看见佛陀的形态,固定在一个位置上,盘腿而坐,穿着藏红花颜色的长袍,沐浴在光和颜色里面,他伸出手来在祝福。
Chaos is a kind of seemingly random , chance or irregular movement , which appears in a definiteness system . based on buck converters , this paper has studied and simulated deeply in the aspect of operation procession , discrete - time modeling , and bifurcation discussion of converters 本文以基本dc / dc变换器( buck变换器)为对象,从变换器工作过程,离散建模,混沌分析等几个方面,进行了深入的理论研究和模拟仿真,并对混沌的应用和混沌控制方面做了一定研究。
It would be foolish to suppose that having developed your definiteness of purpose and pma , you will immediately find that you have the resources you need . the speed at which you acquire these will depend on the size of your needs and on the control you exercise to keep your mind free of fear , doubt , and self - imposed limitations 但是设定明确目标和建立积极心态,并不表示你马上就能得到你所需要的资源,你得到这些资源的速度,须视需要范围的大小,以及你控制心境使其免于恐惧、怀疑和自我设限的情形而定。
