Therefore, the choice of single mode in the examination and the frequency-thick band of mode has been given a particular illumination separately in the paper, following a relative numerical simulation. And a multi-cyclical sine signal modulated by Hanning window is used to simulate the excitation wave, and then an inspected ring of nodes is established to receive the echo, finally how the length of the circumferential cracks, the width of the axial cracks and the degree of the thickness-reduce effect the result is explained through the analysis of the result, further more, the reflection factor in the defect has been calculated.

因此，本文也就单一检测模态的选择以及模态频厚积段的选择分别予以了阐述，并有针对性的进行了数值计算：应用Hanning窗调制的多周期正弦波模拟单音频激励信号，并设置监测质点环接收回波，通过分析说明了管道的周向裂纹、轴向裂纹以及点蚀缺陷对缺陷回波所产生的影响，并进一步计算了缺陷处的反射系数。

Thus, the loading of the slurry and the porous structure can be effectively modulated by above processing parameters. By two-step centrifuging process, because of uniformly thicker slurry coating, the thermal stress resistance of the coating was promptly improved.

通过两次离心挂浆工艺制备的网眼多孔陶瓷，由于结构的均匀性提高，特别是孔筋上的涂覆厚度显著增加，增强了孔筋抵抗脱胶过程中热应力的能力，使得结构中的缺陷减少。

Frequency modulated continuous wave synthetic aperture radar,which combines FMCW technique with synthetic aperture imaging methods,has such advantages as small volume,light-weight,costeffective,high-resolution.

1引言合成孔径雷达具有全天候、全天时、强透射性和高分辨率等优点，已成为重要的军事侦察手段，调频连续波SAR具有体积小、重量轻、成本低和分辨率高等优点，因此，人们对FMCW SAR越来越关注[1-2]。

The surface morphologies of coal pitch spheres were characterized by scanning electron microscope and polarized light microscope. The effects of naphthalene content on the softening point of the modulated pitch, balling temperature on the spheres morphologies and the max mass ratio of pitch to the liquor were investigated.

使用扫描电子显微镜和偏光显微镜对沥青球的表面形貌进行表征，探讨了减黏剂萘含量对调制沥青软化点的影响，成球温度对球形貌的影响以及沥青／水相的最大质量比。

The results show that the coal pitch based activated carbon not only has good sphericity but also narrow particle size; with the same material pitch, the more naphthalene content, the lower the softening point of the modulated pitch. The max mass ratio of pitch to the liquor is 16 and the optimal speed is different using different stirrer.

结果表明：所制得沥青球球形度好，表面光滑，粒径分布范围窄；相同原料沥青，萘含量越高调制沥青软化点越低；沥青/水相的最佳质量比为16；不同的搅拌器最佳速度有所不同。
