顺时针方向的

Methods Six normal volunteers were examined with 1.5 T MRI scanner, and stimulated with the pattern of phase-encoded polar angle with clockwise or counterclockwise rotating wedges, and the pattern of eccentricity with concentric expanding or contracting rings.

方法采用1.5T超导MR设备，运用2种具有相位编码信息的投影刺激：离心外散和向心内聚的光环刺激，以及顺时针和逆时针方向旋转的极角刺激，对6名正常人进行血氧水平依赖的fMRI。

Angular spectral is spectral value map formed by estimating semblable coefficients of fast and slow shear wave or the variation of amplitude ratio of fast and slow shear wave with times and angles at a specified space point based on semblable theory of fast and slow shear wave, the angle value of this space point at a given time can be got by picking the maximum of angular spectral; the study reveals that fast and slow shear wave with different polarization direction should be separated using different rotation formula, eight formulas of separating fast and slow shear wave using clockwise rotation and counterclockwise rotation have been derived, and gained energy assignment rule and phase coincidence rule, in real data estimation, the rotation formula used for separating fast and slow shear wave can be uniquely determined on the two discriminating rules. On the basis of semblable theory of fast and slow shear wave, the delay time corresponding to the maximum of semblable coefficients at a specified point in a given time window is the delay time of fast and slow shear wave, delay time section of fast and slow shear wave can be got by moving space point and smoothing time window. The vertical variation values of delay time of fast and slow shear wave reflect the effect degree of vertical fractured reservoir on fast and slow shear wave which is defined as anisotropic coefficient, and section map of anisotropic coefficient can be obtained.

角度谱就是利用快慢横波的相似性原理，在某一空间点求出快慢横波的相似系数或快慢横波的振幅比值随着时间和角度的变化而形成的谱值图，拾取其极大值就得到该空间点某一时间的角度值；在研究中发现分离不同偏振方向的快慢横波应该采用不同的旋转公式，推导出了利用顺时针旋转和逆时针旋转分离快慢横波的八个公式，并给出了能量分配准则和相位一致性准则两个判别准则，在实际计算中利用这两个判别准则能唯一地确定分离快慢横波的旋转公式；根据快慢横波的相似性原理，在某一给定点和给定时窗内最大相似系数对应的延迟时间就是快慢横波的延迟时间，随着空间点的移动和时窗的滑动就可以得到快慢横波延迟时间的剖面图；快慢横波延迟时间与慢横波传播时间的比值定义为裂缝密度，并求出了裂缝密度剖面图；快慢横波延迟时间纵向上的变化值的大小反映了纵向上裂隙层对快慢横波影响的大小，定义为各向异性系数，并求出了各向异性系数的剖面图。

Using harmonic analysis of the calculated tidal level and current, the distributions of co-tidal lines for K1, O1, M2 and S2 are obtained, whose maximum amplitudes can reach 112 cm, 96 cm, 50 cm and 15 cm, respectively. The distribution of the maximum probable current velocities in Qinzhou Bay is basically the same as that of isobaths, and the maximum probable current velocity can reach 200cms^(-1) nearby the Longmen Harbor. It is concluded by the analysis of K1 and M2 tidal current ellipses that the flow is rotating at the mouth of the bay, while its retilinear flow is in the nearshore area, estuaries and channels. The distributions of the major axes are closely related to the topography, and the rotation directions of both constituents are clockwise.

根据模拟结果计算得到了较以往更为精细的钦州湾K1、O1、M2、S2分潮的同潮图，潮汐最大振幅分别为112、96、50和15cm；最大可能流速的分布基本与等深线一致，龙门港附近最大可能潮流流速可达200cms^(-1)；钦州湾的外湾口海域开阔，一般为旋转流，近岸海区及水道、河口等多为往复流，K1和M2分潮流椭圆长轴的分布与地形密切相关，旋转方向均为顺时针，流速极值出现在龙门港区。

方位角，方位：从某一参考方向测量的地平线的角距离，通常指从地平线北端到通过天体和地平线相交的垂直的圆周上的某一点，一般顺时针测量。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
