1·Apparent velocity and polarization are important characters of seis - mic wave.

视速度和偏振是地震波的两个重要特性。

2·Thus the negative group velocity is simply an apparent velocity as we shall show from the study of energy flow.

因此，负群速度只是表观速度，能流的研究结果也证明了这一点。

3·Relationships of pressure drop across the packing zone with the apparent velocity and flooding volocity with spraying density are obtained.

找出了填料层压降和空塔气速的变化关系，泛点气速和喷淋密度的关系。

4·An inertial controlling scheme to the altitude with the signal of the axis apparent velocity and its integral by the method of conjugate equation is presented in this paper.

本文以飞行器轴向视速度及其积分为控制信号，用共扼方程法设计了一种惯性高度控制方案。

5·And the geophysical methods include TSP, Ground Penetrating Radar (GPR), seismic negative apparent velocity method, HSP and so on and these method have their own advantage each other.

用于超前地质预报的物探方法主要有，TSP法、地质雷达法、地震负视速度法、陆地声纳法、HSP声波反射法等，这些方法在应用中各有所长。

6·Therefore, moveout transform filtering method in T-X domain was adopted, which linearized the curved coherent noise in T-X domain, and remove noise by the contrast of apparent velocity.

为此，采用T-X域时差变换滤波技术，即在T-X域内将曲线型相干噪声线性化，通过视速度差异去除噪声，从而达到压噪目的。

7·It has a very good effect for muting the coherent noise with low apparent velocity. The trial computation results for synthetic and practical data show that the algorithm can simultaneously...

合成数据及实际资料的试算结果表明，该算法在去除随机噪声的同时，能很好的去除较低视速度的相干噪声。

8·The object's apparent brightness yields the distance; its redshift yields the velocity.

这些天体的视亮度可以得到距离，它们的红移可以得出速度。

9·The combination of the two is the apparent wind, which is the relative velocity of the wind relative to the boat's motion.

在两者的结合是明显的风，这是相对速度风相对船的议案。

10·With the concentration of the polymer solution increasing, acoustic velocity of the polymer solution decreases, and the polymer density decreases too, but the apparent viscosity increases.

随着聚合物溶液浓度的增加，其声传播速度减小，其密度值也逐渐减小，但其表观粘度值逐渐增大。
