查询词典 variations

Supposed stochastic variations are perturbed in a small range, we can get a nonlinear equation of these stochastic variations by using a Taylor series or a Neumann series expansion of the system matrix. The application of perturbation techniques translates this nonlinear equation into a pair of constant linear recursive equations. Then we have written a paper "Stochastic Finite Element Method for Interconnect Including Variational Analysis" which has been contributed to 11th Asia and South Pacific Design Automation Conference.

Cluster analysis and two-way contingency table analysis were used to study the ontogenetic variations in the feeding habits of plaice, and the results showed that the feeding activity of plaice did not vary significantly among 7 size classes within the size between 51 mm and 370 mm, but ontogenetic variations were found in the diet composition. In the size class 200 mm, plaice mainly fed on Decapoda and fishes.

A Source, inhibitors, and determinants of change. The system of biological replication does not work with ideal precision; random variations occur which , over the long run, would have a totally self-cancelling and , therefore, leveling and difference-eroding effect unless some factors of bias were operating selectively upon this bounty of variations. This is true of life, in general, and of all aspects of organisms.

a 改变的来源、限制、决定因素：生物的复制系统并不是百分之百精确的，随机发生的变异，最后都会全部自我销毁，除非这些混乱的因素能被选择性的运作与接受，这些击毁和磨损语言的变异才具有影响力，普遍来说，这就是真实的生命，就是生物体的所有面貌。

The theory of accretion disks are important for many astrophysical phenomena, including Quasars, active galatic nucleic, X-ray binary stars, and young stellar objects. The most important branch of accretion djsk theory is the stability properties of djsks. It is widely considered that the luminosity variations of various astronomical objects are associated with the instability of accretion disk. The viscosity plays an important role in the accretion disk theory, and magnetic field exists commonly in astronomical phenomena. A more realistic analysis of the stabihty of the accretion disk should include both the radjal and azimuthal perturbations because of the strong shear of viscous flow.In this paper, according to the luminosity Variations of Various astronomical objects, we study the radial-azimuthal instability of an isothermal with magnetic field. We find that the radial and azimuthal fields B〓,B〓 are mainly responsible for enhancing the instability of the magneto-acoustic modes and non-axisymmetric modes,and that pulsational oscillations are larger in the radial than in the Z direction. The model may be useful in explaining the periodic light variation of FU orionis and. T Tauri stars.

在许多天体物理现象中，例如活动星系核，X-射线双星和年青的恒星理论中，吸积盘理论起着重要的作用，而吸积盘理论中的一个重要分支是吸积盘的不稳定性理论，普遍认为活动天体的周期，准周期光变现象与吸积盘的不稳定性有关，在吸积盘理论中，粘滞起着重要的作用，而磁场是天体物理中普遍存在的现象，对于几何薄吸积盘不稳定性分析，由于强剪切流的缘故，应该包括径向和环向扰动两个方面，本文结合天体物理中的各种周期，准周期光变现象，研究了含磁场的等温薄吸积盘的径向-环向振荡不稳定性，结果表明：磁场的径向和环向分量对磁声模和非轴对称模的不稳定性的增加起着主要的作用，且径向振荡大于轴向振荡，所得结果有利于解释FU Orionis和T Tauri Stars的周期光变现象。

Through concretely analyzing the magnitude and error of deflection of the vertical, we can get the results that the long-period, smaller-range non-tidal variations are commonly less than the tidal ones, but the short-period, larger-range non-tidal variations are comparable to the tidal ones, especially in some areas they are even bigger than the tidal ones, this state can be measured by repeated gravimetry completely.

通过对垂线偏差量级和误差大小的具体分析，得出结论：一般长周期的、幅度较小的非潮汐变化要小于潮汐变化，但短周期的、幅度较大的非潮汐变化则可能与潮汐变化相当，个别地区甚至还会超过潮汐变化，这种情况完全可以用重复重力测量的方法检测到，这也说明重复测量的方法是可行的。
