B. when precision testing equipment, the adjustment process: in the assembly process and equipment are completely assembled to precision testing and adjustment, such as boring bed in the installation process after grinding levelness and straightness calibration, an adjustment and measurement and cannot fully reflect the true error, and requires at least three times and measurement, can eliminate stress, and each must adjust time intervals, it takes about three days.

B。设备精度检测时的调整过程：设备在组装过程中及完全组装后均需进行精度检测及调整，如对镗床床身导轨磨削后在安装过程中的水平度和直线度的校验，一次调整与测量并不能完全反映出其真实误差，而至少需要三次调整和测量，才能消除应力的影响，且每次调整都需有时间间隔，故需时约3天。

The invention discloses a vehicle speed matching method based on linear array CCD image, including the following steps that: two linear array CCD video cameras are respectively arranged on two sections positioned on a road at intervals; both linear array CCD video cameras face downwards and are provided with infrared ray laser source; the frame rate of each CCD video camera is more than 1,000 frames per second, and the resolution is more than 1,024 lines; correlation matching computation of the image sequences obtained by both linear array CCD video cameras is carried out to obtain the time difference of the same object in two image sequences; finally, by means of the time difference and the distance between both cameras, the driving speed of an object vehicle can be obtained according to the velocity formula V=s/t.

本发明公开了一种基于线阵CCD图像的车辆速度匹配方法，该方法在道路相距一定距离的两个断面上分别安装两个线阵CCD摄像机，两个线阵CCD摄像机指向垂直向下，线阵CCD摄像机上配有红外线激光源，线阵CCD摄像机的帧速率大于1000帧/秒，分辨率大于1024线；对两个线阵CCD摄像机得到的图像序列进行相关匹配计算，从而获得同一个目标在两个图像序列中的时间差，利用该时间差和两个摄像机的距离，根据速度公式V＝s/t即可以得到目标车辆的行进速度。

As observed in the Pleistocene, thick intervals of negative δ13C values occur in the Neoproterozoic but are considered to record profound perturbations to the global marine carbon cycle unique to the Neoproterozoic rather than being considered in terms of normal mixed meteoric/marine lithification or decarboxylation.

更新世的观察表明，新元古代存在着一个较长时期的δ13C负值，这些负值记录了全球海洋碳同位素的波动循环是新元古代独有的，而并非通常意义下的大气海洋水混合产生的岩化作用和脱羧基作用。
