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。

To exam the validity of the Bloch-Grüneisen formula at megabar pressures, we use the electrical conductivity data point of ε-iron at relatively low pressure (～40GPa) reported by Keeler as a reference point, a formula for calculating the conductivity of the ε-iron under high-pressure and temperature was deduced via Bloch-Grüneisen,where v is specific volume , T is temperature and σ is electrical conductivity .

为了检验Bloch-Grüneisen公式在兆巴压力冲击压缩下的有效性，本文取Keeler在较低压力下ε相区的一个电导率数据作为参考点，得到了Bloch-Grüneisen公式关于ε-铁在高温高压下电导率的一个解析表达式：σ=〓，这里，比容v的单位是cm〓/g，温度T的单位是K，电导率σ的单位是Ω〓cm〓。

Regarding (6) type, when tradition Time variable t is two spatial vectors (+ psi 1i) and (- psi 2j) Crossed products v also is not 0, it (x1, x2, x3) differs 90 compared to on speed with the three-dimensional space in the space by the pure imaginary number attribute, I=e^I pi, therefore it Number space has in the physical property with the dot product constitution the difference, because Crossed products psi 1i (X psi 2j extremely small visible it is equal to zero under the conventional speed, but is very big in the object movement speed time, Crossed products psi 1i (X psi 2j in the physical quantity and for the quantum mechanics in may not to the easy quantity, its space and the conventional space is different, the performance is intrinsic or the interior space If the definition vector (+ psi 1i) and (- psi 2j) the dot product constitutes the three-dimensional space (x1, x2, x3) is exterior space, but the three-dimensional space which (+ psi 1i) and (- psi 2j) Crossed products constitutes by the vector is the internal space, contrasts its component

对于⑥式，传统时间量t为两个空间矢量(+ψ1i)与(-ψ2j)的叉积比上速度v且不为0，其与三维空间(x1，x2，x3)在空间上相差90度以纯虚数表征，I=e^Iπ，故其与点积构成的实空间有物理性质上的不同，因为在常规速率下叉积ψ1i(Xψ2j非常小可视其等于零，而在物体运动速率很大时，叉积ψ1i(Xψ2j之中物理量与则为量子力学中的不可对易量，其空间与常规空间不同，表现为一个内在或内部性空间。若定义矢量(+ψ1i)与(-ψ2j)点积所构成的三维空间(x1，x2，x3)为外部空间，而由矢量(+ψ1i)与(-ψ2j)叉积而构成的三维空间为内部空间，对比其分量

Partly it has great practical value – you can wrap it around you for warmth as you bound across the cold moons of Jaglan Beta; you can lie on it on the brilliant marble-sanded beaches of Santraginus V, inhaling the heady sea vapours; you can sleep under it beneath the stars which shine so redly on the desert world of Kakrafoon; use it to sail a mini raft down the slow heavy river Moth; wet it for use in hand-to-hand-combat; wrap it round your head to ward off noxious fumes or to avoid the gaze of the Ravenous Bugblatter Beast of Traal (a mindboggingly stupid animal, it assumes that if you can't see it, it can't see you – daft as a bush, but very ravenous); you can wave your towel in emergencies as a distress signal, and of course dry yourself off with it if it still seems to be clean enough.

一方面是由于它有着非常实际的使用价值——当你跳跃着穿越Jaglan Beta的冰冷的月亮中间时，可以把毛巾裹在身上用来取暖；在Santraginus V的灿烂的大理石沙子的海滩，你也可以躺在毛巾上，呼吸浓烈醉人的海洋蒸汽；也可以在Kakrafoon的沙漠世界里，在红色的恒星照耀下，盖着毛巾睡觉；用它做帆，在缓慢宽阔的Moth河上泛舟；在近身搏斗中打湿了做武器；包住脑袋来防止毒气侵袭或者避开Traal的贪婪虫鸣兽的喋喋不休（一种发自内心的愚蠢的动物，它总是认为如果你看不到它，它也就看不到你——蠢得像灌木，却很贪婪）；可以在紧急情况下挥动毛巾表示求救信号；当然，也可以用来擦干身体——如果它看起来还是足够干净的话。

If the roundoff is 0, the representation is exact , and V is exactly representable in the type T .

如果舍入为0，则表示是精确的， V 在类型 T 中可以精确表示。

If the roundoff is not 0, the representation is inexact , and V is inexactly representable in the type T .

如果舍入不是0，则表示是不精确的， V 在类型 T 中不能精确表示。
