查询词典 instability constant

Axis of maximum moment of inertia = the axis of figure: because the Earth is not a perfect sphere, but is physically an oblate spheroid, the position of the axis of figure is not a precise constant, but is affected by the constant change in the earth's distribution of total mass:(ie, by ocean tides, atmospheric cond- itions, plate tectonic movements, etc.).

轴最大转动惯量=形状轴：因为地球不是完全的球形，而是一个扁球体，形状轴的位置不是精确的常量，而是受地球总质量的分配持续变化作用：（也就是，受海洋潮汐、大气环流、地质板快运动等等）。

And by applying the linear dispersion relation of wave, all the properties of wave refraction including wave rays, constant phase lines, phase function and crest lines etc., can be expressed in explicit functions. By introducing an orthogonal curvilinear coordinate along the wave ray and the constant phase line, and with an estimated scale factor, the refraction coefficients along any wave ray can then be determined. The present results are verified by ordinary wave ray theory and some previous numerical results.

就此特例情况在波浪的线性分散关係的应用下，前进波浪折射现象的整体特性，包括波向线、等位相线、位相函数与波峰线皆被导述出明確显然的函数表示；同时引入由沿著波向线与等位相线所构成的完全符合波浪折射几何通性的正交曲线座標，求出其尺度因子后，由能通量守衡原则定出沿著任一条波向线上的折射係数；並由之对往昔纯依两相邻的波向线间的几何类比所给定的折射係数给予导証之。

The number of desired signals is detected by using singular value decomposition. And the array input is transformed into the signal subspace. Orthogonality is derived for the weight vectors in multiple beamforming on this subspace. According to which, an orthogonal constant modulus algorithm is proposed by introducing the orthonormalization procedure into the static least square constant modulus algorithm.

利用奇异值分解确定了用户信号的个数，并把天线阵接收的数据矩阵映射到信号子空间上，进而在该空间中讨论波束形成问题并导出了多用户波束形成的必要条件，依据此条件将正交化过程引入最小二乘恒模算法并提出了正交化恒模算法。

Since a pentode presents a fairly constant current sink, trying to power it from a constant current source will be fairly unsuccessful, sort of like the unstoppable object hitting the immovable object.

因为五级管本身就表现得类似恒流陷阱，试图用恒流源驱动五级管只会是个失败，就好像试图用一个停不下来的物体去打击一个不可移动的物体。

She still remained one of my earliest recollections,not only as a person,but as a fountain of authority over my conduct and of security for my physical welfare ,and of active and constant affection and love .she was an active and constant percept for decent behaviour .

2至今她仍是我最早记忆的一部分，我记得的不仅是这个人，她还是我行为规范和物质福利可靠的来源，也是积极、持久的情感与爱的源泉。她也是正直行为积极与持久的准则。

The short period mode is an oscillation of the pitch of the aircraft at mainly constant speed while the phugoid mode is an oscillation of the pitch at mainly constant angle of attack.

短周期是在等速运动下飞机俯仰的振荡，长周期是在攻角保持定值下飞机俯仰的振荡。

In constant-bank phase, a large constant bank angle is used.

在常数倾斜角飞行段，采用一大的常数倾斜角控制。

As a windfall of such analysis , It points out that physical constant of permittivity in vacuum actually is an constant without physical dimension .

给出了常见的50余个物理单位和物理量的时空组态和时空结构。作为一个分析结果发现，真空介电常数实际上是一个无量纲的物理常数。

The constant, h, is known as Planck's constant.

常量h就是普朗克系数。

The Planck constant is just determined by the Wave constant.

由波常数决定普朗克常数h

These rules reflect some inherent feature of self and nonself, and they are the basic detection criterion of GECISM.

这些规则反映了"自我"和"非我"的内在特征，是GECISM进行"非我"检测的判据。

Until today, the media from China and the outside world still uses the term "Post 89". Regardless to whether it is for commercial gimmick or convenience, everybody still remember "Post 89", a term which carries a strong Cantonese accent.

时至今日，国内外艺术媒体还是在沿用&后八九&这个称谓，不管当初是为了商业噱头还是容易上口好记，反正大家现在是记住了&后八九&这个广东口音很重的词。
