By electromagnetic theory, for the case that the magnetic dipole source and the receiver are set in seawater, the general expressions of frequency_domain electromagnetic responses for a layered benthal model are deduced. From those, the transient response expressions of three common configurations—vertical magnetic dipole_dipole, central loop, and coincident loop, located on the surface of uniform half_space seafloor, are derived respectively, supposing that seawater is uniform half space, or its depth is finite.

根据电磁场理论，推导了磁偶源和接收点均位于海水中时层状海底模型的频域电磁场响应一般表达式，并通过此式，得到了海水为均匀半空间和有限海水深度两种情况下，垂直磁偶极装置、中心回线和重叠回线分别置于均匀半空间海底表面时的瞬变电磁响应表达式。

Moreover, the perpendicular distances from the temples and the highest point, where the nerve enters the frontal muscle, of the frontal branch of the facial nerve to the FP line were recorded as well. Results On the AE line, the facial nerve went across the anterior portion inside the hairline (39.3 mm anterior to the otobasion superius).

以蝶骨嵴根部的体表投影为中心，作起于鬓角，沿发际前缘弧形向下，止于耳上基点前39 mm，位于发际内的长约5 cm的翼点锁孔入路切口，是不损伤面神经的理想切口。

along the hairline, one arc-shaped incision about 5 cm in length with a center at the surface projecting point of the sphenoid ridge root, extending from the temples to the point 39 mm anterior to the otobasion superius, is an ideal skin incision via the pterional keyhole approach with intact frontal facial nerve.

以蝶骨嵴根部的体表投影为中心，作起于鬓角，沿发际前缘弧形向下，止于耳上基点前39 mm，位于发际内的长约5 cm的翼点锁孔入路切口，是不损伤面神经的理想切口。

In the United States, chronic alcoholism and hepatitis C are the most common ones.

在美国，慢性酒精中毒，肝炎是最常见的。
