对称的

Diffusive fluxes are roughly symmetric around the magnetic equator during equanoxes. But they are asymmetric during solstices, the winter hemisphere has smaller fluxes than the summer hemisphere does.

在分点，南北半球的扩散通量和扩散速度大致对称；而在至点，扩散通量存在着明显的南北半球不对称现象。

The minimal supersymmetric standard model is indeed the simplest and most interesting supersymmetric model.

最小超对称标准模型是最简单的也是唯象上最感兴趣的一种超对称理论。

Based on the newsboy model and Bayesian analysis, supply chain system in demand forecast update conditions with asymmetry is described in order to analyze the asymmetry information and double marginalization.

本文在报童模型和贝叶斯分析模型的基础上对不对称信息下具有需求预测更新的供应链系统进行了描述，并分析了信息不对称和双重定价问题。

4 When evaporative cooling hydro-generator (generator/motor) is running off-centered instantaneously under accident condition, it shall be 20s if we multiply square of ratio between negative sequence current weightand rated current (pre-unit value) by allowed dissymmetric runtime t (I2/In)2t.

6.4蒸发冷却水轮发电机在故障情况下短时不对称运行时，应能承受的负序电流分量与额定电流之比的平方与允许不对称运行时间 t 之积(I2/In)2t 应为20s 。

Results show that there are components of asymmetric pressure and velocity in symmetric structure, but this portion affect normal phonation little due to its limited ratio (less than 10%).

结果表明，对称结构下存在着非对称压力和速度成分，但是由于它所占的比率有限（不超过10%），对正常发声的影响不大。

Any vertex closer to the mirror plane, than the limit we set, will be placed exactly on the mirror plane.

任何与实际对称平面距离小于我们所设置的重合范围的点都将会直接放在对称平面上。

Radially symmetrical, so that a line drawn through the middle of the structure along any plane will produce a mirror image on either side.

辐射对称 Actinomorphous 辐射状对称，通过结构中央的任一平面都能将其分成互为镜像的两部分。

The recess (13) has a bottom surface (14) transverse to the plane of symmetry and substantially parallel walls (15) along said plane.

该凹槽(13)有一个横切对称平面的底面(14)和与所述对称平面基本平行的内壁(15)。

This paper mainly discusses a kind of indefinite stochastic linear quadratic optimal control problem with incomplete data, which can be described as: Minimize subject to Here Q, F are indefinite symmetric matrices,R is a positive semidefinite symmetric matrix.

本文主要讨论的是一类部分信息下的不定随机LQ问题，其形式如下：这里Q，F为不定对称矩阵，R为非负对称矩阵。

The characteristic vector of the real symmetric matrix should be found out, which is orthogonalized and normalized to a standard orthogonal base and is used as row vector to construct the transformation matrix P, so the P~(-1)AP can be made into diagonal matrix.

实对称矩阵A经相似变换P-1AP可化为对角矩阵，在x =Py 下，不一定能化A的二次型为标准型；应寻求对称矩阵A的特征向量，将其正交化并单位化作为标准正交基，作为列向量构造变换矩阵P，可使P-1AP=Λ为对角阵，在x =Py 下，要将二次型化为标准型，且二次项系数即为对角阵Λ主对角线上元素。

As she looked at Warrington's manly face, and dark, melancholy eyes, she had settled in her mind that he must have been the victim of an unhappy attachment.

每逢看到沃林顿那刚毅的脸，那乌黑、忧郁的眼睛，她便会相信，他一定作过不幸的爱情的受害者。

Maybe they'll disappear into a pothole.

也许他们将在壶穴里消失
