    • An inductor may include a planar ferrite core. A first group of one or more grooves is formed in a first side of the ferrite core. A second group of two or more grooves is formed in a second side of the ferrite core. The grooves in the first and second groups are oriented such that each groove in the first group overlaps with two corresponding grooves in the second group. A first plurality of vias communicates through the ferrite core between the first and second sides of the ferrite core. Each via is located where a groove in the first group overlaps with a groove in the second group. A conductive material is disposed in the first and second groups of grooves and in the vias to form an inductor coil.
    • 电感器可以包括平面铁氧体磁芯。 第一组一个或多个凹槽形成在铁氧体磁芯的第一侧。 在铁氧体磁芯的第二侧形成有第二组两个或多个凹槽。 第一组和第二组中的凹槽被定向成使得第一组中的每个凹槽与第二组中的两个相应的凹槽重叠。 第一多个通孔在铁氧体磁芯的第一和第二侧之间通过铁氧体磁芯连通。 每个通孔位于第一组中的凹槽与第二组中的凹槽重叠的位置。 导电材料设置在第一和第二组沟槽和通孔中以形成电感线圈。

    • An approach is provided for a multi-component seismic data processing that separates P-type and S-type seismic waves in an affine coordinate system. A method for separating and composing seismic waves comprises: determining base vectors of the seismic waves; transforming and separating the seismic wave in an affine coordinate system; and obtaining a signal with true amplitudes and eliminating a mode leakage phenomenon. Therefore, the method achieves the wave separation and recovers the amplitudes of separated waves simultaneously, which reduces noises to provide more precisely seismic data and to satisfy the requirement of seismic data analysis and processing.
    • 提供了一种用于在仿射坐标系中分离P型和S型地震波的多分量地震数据处理的方法。 一种用于分离和组合地震波的方法包括:确定地震波的基矢量; 在仿射坐标系中转换和分离地震波; 并获得具有真实幅度的信号并消除模式泄漏现象。 因此,该方法实现了波分离,同时恢复了分离波的振幅,减少了噪声,提供了更精确的地震数据,满足了地震数据分析与处理的要求。
