The only difference between these two cells was that in Lenard's cell the electrons were taken from the cathode by light, whereas on the "3-electrode lamp" the cathode is a white-hot filament capable of sending into the vacuum currents of much higher intensity.

在研究过程中，莱纳德还发明了一种光电管，以加速电子和测量它们的能量，这种光电管是三极管最初的雏形，不同之处在于，在莱纳德的光电管中，电子是由阴极光发射的，而三极管中的阴极是白炽丝，可以向真空发射更高强度的电流。

The results show that the chlorite jade is in dark green, semi-translucent to opaque, and lepidoblastic texture, with hardness of 2.5, refractive index 1.58 and density 2.60 g/cm^3.
