写在前面：这个对横波纵波理解还是很有帮助的，电路也比较简单，可以用这个电路来观测一些纵波特性。
Longitudinal Waves and Transverse Waves tests

created on 10-01-98 – JLN Labs – last update on 04-09-99
The following is an electric wave experiment to demonstrate the inverse relationship between the coil, or magnetic inductor and the capacitor, or electrical inductor, and their usage in propagation of the electromagnetic field components.
下面是一个电波实验来展示线圈 或 磁电感和电容，或电感，和它们在电磁场分量在传播过程中的使用 之间相反的关系。
An analog computer is used to study the space distribution of the electromagnetic field component of transverse and longitudinal waves along a transmission line in two different configurations (LMD/TEM).
一个模拟计算机被使用来学习横波和纵波，在2个不同配置（LMD/TEM)，沿着一个传输线的电磁场分量的空间分布。
This is the electricity Tesla was propagating from his Magnifying Transmitter. In the Tesla’s Magnifying Transmitter, the energy is countinuously bounced back and forth between the earth and the reflecting capacitance at a rate timed to a natural rate of the earth…..
这是特斯拉从他的放大发射机传播的电。在特斯拉的放大发射机，能量总是持续不断地前后弹，在地球和反射电容之间，在一个和地球频率调谐的频率上。

TEST N°1) The TEM Transmission Line:
测试1：TEM传输线（横波）
The TEM (Transverse ElectroMagnetic) line is the analog simulation of transverse EM waves propagation in space coming from two parallel wires, this is the conventional flow of EM radiation.
TEM(横电磁）线是来自于2条平行线的对横电磁波在空间传输的模拟仿真，这是电磁辐射传统的流动。
You may notice that the Magnetic energy is in Space OPPOSITION with the Dielectric energy
你可能注意到了，磁能量总是和非传导性的能量，空间反相。
TEST N°2) LMD Transmission Line:
测试2：LMD传输线
The LMD (Longitudinal Magneto-Dielectric) line is the analog simulation of longitudinal EM waves propagation in space coming from two parallel wires, this is the unconventional flow of the EM radiation.
LMD(纵向磁介质）线是来自2条线的纵向电磁波在空间传播的模拟仿真，这是电磁辐射的非常规性流动。
You may notice that the Magnetic energy is in Space CONJUCTION with the Dielectric energy
你可能注意到了，磁能量总是和非传导性（介电）能量，空间相结合的，也就是同相。

Additional notes :
附加注意事项：
Each coil has been checked (with an LC oscillator circuit) so as to obtain the same inductance ( L=1.58 mH).
每个线圈已经检查过了（用LC震荡电路），因此获得了相同的电感（L = 1.58mH)
Coils specs (L1 to L8) : about 150 turns (l=85mm) of 4/10 mm on a ferrite rod ( l=120 mm, 9 mm diam)
线圈规格（L1到L8):大概150圈（长度85mm）0.4mm漆包线缠绕在一根铁氧体棒上（长=120mm，9mm直径）
All voltages measurements have been done with an oscilloscope.
用示波器测量的所有电压。
