查询词典 extinction

Chief among the candidates for extinction is the rare white lemuroid ringtail possum, a singular species that Flannery, the paleontologist, describes as "our panda."

By the theory of difference equation and the construction of proper vector Liapunov function, we for the first time get the sufficient conditions for the permanence, extinction and balancing survival for this ndimensional system, which are all independent on the delays, hence under peroper conditions the time delays of this system are both harmless and profitless.

通过运用差分方程理论以及构造适当向量Liapunov泛函的方法，首次得到了此类系统多维自治的情形下系统持续生存、灭绝和残存的充分条件，这些充分条件均不依赖于时滞，因而在一定条件下，此系统中的滞后因素既是无害时滞也是无益时滞。

Unfortunately in the material-laden society, the glory of such a love is as feeble as lightning bug, and furthermore,"love" sometimes paves the way for the degeneration of those ignorant men and women, so that Venus can't help uttering a deep sigh:"Since the folks on the planet are on their way to extinction, love becomes a game. What a miserable thing!"

不幸物欲充塞的现世界，这种恋爱的光辉，有如萤火之微弱，而且"恋爱"有时适成为无知男女堕落之阶，使维纳斯不禁深深地叹息："自从世界人群趋向灭亡之途，恋爱变成了游戏，哀哉！"

The results show that volume concentration and magnetic field intensity have a great impact on refractive coefficients and extinction coefficionts of ferrofluids.

实验制作了光纤端面浸没在磁性液体中的传感元件，设计了测量光路系统，得到了反射率随外加磁场强度变化的情况，与理论分析结果相吻合。

An environmental imbalance on Earth brought about the extinction of the dinosaur and gave rise to the emergence of mammalia.

Nick Polunin, a marine scientist at the U.K.'s Newcastle University, said continuing damage to coral reefs due to bleaching could affect food webs and cause the localized extinction of fish species.

In order to find a powerful assistant computation tool for further analysis and design of multilayer optical coatings,an analytical model is mathematically established for accurate calculation of the first and second derivatives of the spectral coefficients of multilayer optical coatings with respect to layer parameters like thickness,real refractive index and extinction coefficient. It is based on the matrix theory of calculating the spectral coefficients of multilayer optical coatings and is achieved by perfectly using the trace operation of matrix.

为了寻找一种膜系深入分析与设计的有力辅助计算工具，从光学薄膜光谱系数的矩阵计算理论出发，基于对矩阵求迹运算的巧妙运用，从数学上建立了准确计算膜系光谱系数关于膜层几何厚度、实际折射率和消光系数等膜层参数的一阶和二阶偏导数的解析模型。

For example, the most recent mass extinction, the one 65 million years ago that included the die-off of dinosaurs, probably was caused by an asteroid collision as scientists theorize and Mayhew agrees.

其实英语单词和汉字一样，存在着很多的"偏旁部首"，知道了偏旁部首你就可以根据它们直接来猜测单词的意思，虽不说百分之百猜准，但起码可以猜测个大概，至少在别人告诉过你单词的意思后你可以恍然大悟地领会它，这样就可以大大增强你对英语单词"见字识意"的能力，做到真正认识一个单词，而把它的汉语意思仅做为一般参考。

Pounds plus 2 1/2 % interest on the same, repayable quarterly in equal annual instalments until extinction by amortisation of loan advanced for purchase within a period of 20 years, amounting to an annual rental of 64 pounds, headrent included, the titledeeds to remain in possession of the lender or lenders with a saving clause envisaging forced sale, foreclosure and mutual compensation in the event of protracted failure to pay the terms assigned, otherwise the messuage to become the absolute property of the tenant occupier upon expiry of the period of years stipulated.
