本文指出了测量光学材料折射率的最小偏向角法和V棱镜法国内外所有文献的原理公式误差，重新推导了最小偏向角法和V棱镜法测量折射率的正确公式。基于最小偏向角法用精密测角仅可以获得±3×10-6的折射率的测量精度，然而，这些文献沿用经典的测量原理公式却具有-4×10－4数量级的原理公式误差，因此导致错误的测量结果。

the conditions of acquisition of minimum deviation is proved by means of rolle's theorem and the reversibility principle of beam path for triple prism, it is that the angle of incidence is equal to the angle of emergence for monochromatic incident beam.

利用数学中的罗尔中值定理及光路的可逆性原理证明了三棱镜获得最小偏向角的条件，即单色光线的入射角等于出射角。

计算表明，用经典公式计算标准试样折射率虽然对光学系统象差影响很小，但作为折射率基准测量，这样大的原理公式误差是不允许的。

The results show, when the prism wedge angle is 4°, the transmitted laser beam changes about 1 μrad as the prism rotates 1′; when the small angle deviation on one side of the minimum deviation angle of each prism is controlled, the scanning range of laser beam in the horizontal and vertical direction is not less than 500 μrad, and the scanning precision of the device is superior to 0.2 μrad.

结果表明：取棱镜棱角α为4°时，棱镜每旋转1′，透射光束变化约1 μrad；分别控制双棱镜在其最小偏向角一侧小角度偏转，可以实现光束在水平方向和垂直方向500 μrad范围内的精确扫描，装置的扫描精度可以达到0.2 μrad。

As a result, the mass matrix, the stiffness matrix, the damping matrix and the excitation coefficient matrices of the dynamics differential equations are random parameter matrices. According to the minimum deviation rule of the mean squares between the random parameter system and the deterministic parameter system, the random mean square deviation vector function between the two systems has been set up and the deterministic parameter system has been solved.

应用Newton-Euler矢量法对挂接车辆系统建立了质量阵、刚度阵、阻尼阵和激励系数阵皆为随机参数阵的八自由度随机参数系统动力学微分方程，并按照随机参数系统与确定性参数系统之间的均方值偏差最小的原则，建立了两系统之间的随机均方偏差矢量函数，由此解出了相应的确定性参数系统

随着死亡的吉他手Schuldiner接受主唱的职务，乐队在现实中树立了重要的影响。

But he could still end up breakfasting on Swiss-government issue muesli because all six are accused of nicking around 45 million pounds they should have paid to FIFA.

不过他最后仍有可能沦为瑞士政府&议事餐桌&上的一道早餐，因为这所有六个人都被指控把本应支付给国际足联的大约4500万英镑骗了个精光。
