查询词典 hyperbolic

Firstly, some basic properties of the limit shadowing are given; Secondly, we give the characterization of both lin-ear automorphisms and linear flows on R~ with the limit shadowing property; Thirdly, as applications we prove that the hyperbolic endomorphisms on T~ have the limit shadowing properties, Smale "horseshoes" have the same prop-...

首先，给出了极限跟踪性的一些基本性质；其次，得到了n维欧氏空间上线性自同构及线性流具有极限跟踪性的特征；最后，作为应用证明了双曲环面自同态以及Smale&马蹄&在其不变集上具有极限跟踪性。

In this paper, we consider the Expanded Mixed Finite Element Method for the 2nd quasilinear parabolic problem and the 2nd quasilinear hyperbolic problem.

本文中我们采用扩展混合有限元方法数值模拟了二阶拟线性抛物问题和二阶拟线性双曲问题。

In Chapter 4, by means of the result obtained in Chapter 2 and as in the autonomous case, the author adopts a direct constructive method and obtains the local exact controllability for general nonautonomous first order quasilinear hyperbolic systems.

在第四章，作者以第三章建立起来的半整体C~1解理论为基础，采用一个与自治系统情况相似的直接构造方法得到了非自治一阶拟线性双曲组的局部精确能控性。

To call Levitt a "rogue economist" may be a tad hyperbolic. Certainly this epitome of antistyle ("his appearance is High Nerd: a plaid button-down shirt, nondescript khakis and a braided belt, brown sensible shoes") views the workaday world with different eyes; the young economist teases out meaning from juxtapositions that simply would not occur to other researchers.

如果称列维特为'流氓经济学家'也许有点夸张，当然这个反流行的典范（&他的外表相当讨厌：一件领尖订有钮扣的衬衫，极普通的卡其裤，一条麻花状的腰带，褐色的鞋子&）以不同的眼光看这个世界；这位年轻的经济学家轻易便能从并列的事物中发现其他研究者所不能发现的意义。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
