The image you sent is a labeled diagram of an oscilloscope displaying a waveform. The oscilloscope is set to measure voltage in volts per division (V/div) and time in milliseconds per division (ms/div). The waveform appears to be a sine wave with a period of about 8 milliseconds.
The text on the image says "Laboratory work No. 8" and "Study of pulses and pulse-current in linear electric circuits." The tables below the oscilloscope diagram show the characteristics of the pulse and pulse current. The first table is for Oscillogram 1 and the second table is for Oscillogram 2.
The tables include the following columns:
* K: This is the scale factor for the voltage measurement.
* Umax: This is the maximum voltage of the pulse.
* T: This is the period of the pulse.
* tp: This is the pulse width.
* v: This is the pulse area.
* Q: This is the pulse charge.
* k: This is a dimensionless coefficient.
