What are the characteristics of the triode?

The characteristics of the triode can be divided into input characteristics and input characteristics. 1. The input characteristic curve of the input characteristic triode, which indicates the relationship between Ib and Ube, and its characteristics are:
(1) When Ube<UbeR, Ib≈O says that the section of (0~UbeR) is “dead zone”. When Ube>UbeR, Ib increases with the increase of Ube. When zoomed in, the triode works in a relatively straight section. .
(2) When Uce is in the range of 0-2 volts, the position and shape of the curve are related to Uce, but when Uce is higher than 2 volts, the curve Uce is basically irrelevant. The normal input characteristics are represented by two curves.
2, output characteristics Output characteristics represent the relationship between Ic and Uce, it is divided into three areas: cut-off area, saturation area and amplification area.
When the Ube<0 in the cut-off area, Ib≈0, that is, Ic=Iceo, is called the penetration current. At normal temperature, the Iceo is about several microamperes, and the fistula is about several tens of microamperes to several hundred microamperes.
At normal temperature, the Icbo of the silicon tube is less than 1 microamperes, and the Icbo of the fistula is about 10 microamperes. For every 12 °C increase in temperature, the Icbo value is doubled, and the temperature of the silicon tube is increased by 8 °C, Icbo value. Doubled.
In the saturation region, when both the emitter junction and the collector junction are in a forward bias state, Ic does not substantially change with Ib, and the amplification function is lost.
In the amplification region, when the crystal triode emitter junction is in a positive bias and the collector junction is in the reverse bias operation, Ic changes linearly with Ib, and the amplification region is a region in which the triode operates in an amplified state.

Root Barrier

HDPE is the main component of root-blocking board, which has excellent resistance to root puncture and can resist most plant roots. Mainly used in planting roof greening, garage roof greening on the ordinary water-blocking layer, to prevent plant roots puncture damage water-blocking layer caused roof leakage.

It has good physical and mechanical properties, high tear resistance, strong deformation adaptability, puncture resistance, oil and salt resistance, acid and alkali resistance, corrosion resistance, high and low temperature resistance, and long service time. Water blocking, drainage and water leakage prevention have good effect, complete thickness specifications, low cost and simple construction.
