focal depth

From the epicenter of the distance to the source told focal depth.

从震中到震源的距离叫震源深度.

The worst condition for seismomagnetic observation appears when the fault is located at the magnetic equator, or orients magnetic E-W, or with a focal depth of 10 km o> r more. Under one of such circumstances the corresponding piezomagnetic anomaly can hardly be detected.

在最差观测条件时压磁异常量几乎无法测出，这时断层位于磁纬0°处，或走向为E-W，或埋深为10公里左右。

The focal depth was about 6 mi.

震源深度约6哩.

This technology has the advantages of no mask, long focal depth, and high resolution, low cost.

焦深长，分辨率高，无掩膜，成本低是该技术的优点。

Multifocal intraocular lens has a wide focal depth can acquire a better whole range vision.

多焦点人工晶状体具有较宽的焦点深度范围,从而可获得良好的全程视力.

The transmitted field characters of h-SIL are affected by the material dispersion with illuminating lights of different wavelengths, The resolution, focal depth, focused intensity of h-SIL are sensitive to the change of wavelength and have a periodic oscillation whh the wavelength's change.

对应不同波长的照明光，h-S1L的材料色散作用将对其透射场特性产生影响。h-SIL的分辨率、焦深和聚焦强度对照明光的波长变化非常敏感，都随着波长的变化成周期性的振荡。
