向后的

A lateral pass from the back receiving the snap from the center to another back behind the line of scrimmage.

横传一记横传，在对阵争球线后由一个接到从中间向后传的球的后卫自中心向另一后卫传出

Our eyes are placed in front because it's more important to look ahead than to look back.

我们的眼睛长在前面是因为向前比向后看更重要，如果你向后看你的旅程已经结束。

The undercarriage was a tricycle arrangement, with the wide-track main units retracting inwards into the wing and the nosewheel retracting backwards (following a 90 degree rotation) into the area beneath the cockpit.

飞机起落架是一个类似三轮车布局，配制宽轨的主起落架部分可以向后缩进机翼内，前轮向后回缩（自转90度）进座舱下部的区域。

The method comprises the following: a step of calibrating a camera, which is to utilize a Taylor series model to calibrate an omni-directional vision sensor so as to obtain internal parameters of the camera; a step of obtaining epipolar geometric relation, which comprises the steps of calculating an essential matrix between binocular omni-directional cameras and extracting the rotation and translation component of the cameras; a step of correcting an outer polar line, which is to correct the outer polar line of a shot omni-directional stereo image so as to allow a corrected polar quadratic curve to coincide with an image scan line; and a step of three-dimensional reconstruction, which is to carry out feature point matching to the corrected stereo image and calculate the three-dimensional coordinates of points according to matching results.

该方法的步骤包括：相机标定：利用泰勒级数模型对全向视觉传感器进行标定，得到相机内参；对极几何关系求取：包括计算双目全向相机之间的本质矩阵，并从中提取相机的旋转和平移分量；外极线校正：对所拍摄的全向立体图像对进行外极线校正，使校正后的极二次曲线与图像扫描线重合；三维重建：对校正后的立体图像对进行特征点匹配，根据匹配结果计算点的三维坐标。

Two polar nuclei move to the micropylar end before sperm is released in a gap between the egg cell and central cell and subsequently taking off cytoplasm one after another. The sperm nucleus moving to the egg nucleus runs faster than the one to the polar nuclei. It fuses with the polar nuclei that are moving towards the antipodal cells at the chalazal end.

精子释放前，两极核移向卵细胞的合点端；两精子释放于卵细胞与中央细胞的间隙后，先后脱去细胞质，然后分别移向卵核和极核，移向卵核的精核快于移向极核的精核；精核与两极核在向反足细胞团方向移动的过程中完成雌雄核融合。

If a user operates an operation panel to input an instruction for normal playback, then a control circuit of a digital television monitor determines a frame to be played back at present as a noticed frame and requests the hard disk recorder for image data of successive 15 frames forwardly and backwardly adjacent the noticed frame and image data at positions of time intervals of 0.5 seconds within a range of 2 minutes forwardly and backwardly of the noticed frame through an IEEE 1394 cable.

如果用户操作操作面板输入正常播放指令，那么数字电视监视器的控制电路确定当前播放的一帧作为标记帧，并且通过IEEE1394电缆向硬盘记录器请求标记帧的向前和向后连续的15帧的图像数据以及标记帧向前和向后2分钟范围内在0.5秒时隙内的位置的图像数据。

After being loaded with horizontal retraction force at various height, displacement and stress distribution of anterior teeth was not well-distributed. Labiolingual displacement of incisors varied from crown lingual tipping to lingual translation and lingual controlling root movement, while canine mainly showed crown lingual tipping. The displacements of teeth increased with the length of hook but their moving tendency remained unchanged. Stress distribution in PDL was in accordance with teeth displacement.

2水平向后牵引力的作用点升高时，上前牙的位移和应力分布趋势各不相同：切牙的唇舌向位移由冠舌向倾斜逐渐变为舌向整体移动和舌向控根移动，尖牙则以冠舌向倾斜位移为主；前牙位移量随牵引力高度增加而增大，但位移趋势较为稳定；牙周膜应力分布与其位移趋势相一致。

Jazz, Blues, Tap, Waltz,Polka etc, these all haved moves from the vernacular into the rarified realm of the Elite.

但是让我们向后看，再向后看，看看那些从民间和街上诞生的舞蹈，你就会明白我的想法。

Experiments show that it is realizable to use the two-component OEHF-LDA in backward scattering mode.

本文对二维OEHF—LDA用于后向接收的可行性进行了探讨和试验并获得成功，这是采用小功率激光器实现后向散射接收二维LDA测量的首次尝试。

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。
