查询词典 critical point

In contrast to the situation for a homogeneous isotropic neo-Hookean sphere, it is shown that not only there exists a secondary turning bifurcation point on the cavitated bifurcation solution which bifurcates locally to the left from trivial solution, and also the critical load is smaller than that for the material with no perturbations, as the parameters belong to some regions.

In this paper, we firstly make some qualitative analysis to Lorenz critical chaotic system, and then lead it to the corresponding unstable equilibrium point and periodic orbits in terms of the linear state feedback approach. Then we make a lot of simulations which indicate this method to be feasible. Fractional-order system, as well as Lyapunov exponent, has been used as a powerful tool for the quantitative study of chaotic systems.

以对二甲氨基苯甲腈为探针，测定它在表面活性剂(C12TABr、SDS、C12E23、C12-3-12·2Br)水溶液中的第二重荧光强度和对应的特征波长对表面活性剂浓度曲线，由Ia-c 曲线的转折点或λa-c曲线对应的一阶导数极小点可以获得临界胶团浓度。

The results were found as following:(1) The damage value increases more significantly with the increase in PVF before 30% PVF, beyond which the increasing trend becomes gradually gentle.(2)Keeping the interphase strength and PVF unchanged, the damage increase with increasing moisture concentration in a nearly linear relation.(3)The results generated from the FCC model with consideration of the interphase debonding are in good agreement with the experimental data, meanwhile, the FCC model is also capable of predicting the critical load for the damaged and the undamaged dental composite subject too the 3-point flexural test.4 A 3D-fmite element analysis has been successfully exploited to examine the mechanical behavior of the restoration-tooth structure under the polymerization shrinkage and water sorption. It was found:(1) The low stiffness of the composite has the effect to limit the displacement occurring in the remaining tooth tissue. For lower interphase, the cuspal flexures are litter higher. The high interphase modulus acts as a \'shielding effect\' for stress transfer.

得到如下结论：(1)相同的吸湿性，在30％PVF(颗粒体积分数：Particle volume fraction，PVF)前增加PVF，层间脱胶损伤值显著增加；此后损伤值的增加趋于平缓；(2)保持层间强度和PVF不变，层间脱胶损伤随吸湿率的增加而接近线性增加；(3)FCC(面心立方：Face-centred cubic，FCC)模型层间脱胶损伤的预测结果和实验数据基本吻合；同时此模型可以用于预测牙齿填充材料三点弯曲实验的临界载荷。4、建立理想牙齿修复结构，利用有限元方法研究了同时考虑聚合收缩和吸湿膨胀耦合作用下的填充修复材料和粘结界面层材料性能对牙齿修复结构的力学行为的影响，得到如下结论：(1)低弹性模量的牙齿填充修复材料能限制天然牙组织的位移，但天然牙组织的位移与粘结界面层的弹性模量无关。

The whole field of ethical science was thus left at the exclusive command of the writers who followed Grotius; and it still exhibits in an extraordinary degree the traces of that entanglement with Roman law which is sometimes imputed as a fault, and sometimes the highest of its recommendations, to the Grotian theory Many inquirers since Grotius''s day have modified his principles, and many, of course, since the rise of the Critical Philosophy, have quite deserted them; but even those who have departed most widely from his fundamental assumptions have inherited much of his method of statement, of his train of thought, and of his mode of illustration; and these have little meaning and no point to the person ignorant of Roman jurisprudence.

这样一来，全部伦理学的领域便完全留归追随格罗修斯的著者们控制了；它在很大程度上仍表现出和罗马法纠缠在一起的迹象，这有时被认为是对格罗修斯理论的一种过失，但有时则被认为是对它的最高贡献。

So the steps to decrease the level of aflatoxin and to prevent the peanut from being re-contaminated by aflatoxin should be taken as the critical control point. The measures to control the moisture content and remove unsound kernel including moulded kernels, damaged kernels, sprouted kernels and immatured kernels should be taken as the measures to prevent and control aflatoxins in peanut.

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。
