"Triode valve" does not make sense. Please restate the question.
Umm... yes, it *does* make sense.
Triode "valve" is non-U.S. English for Triode tube.
OK.
Amplification factor is the amount of anode voltage change to give a chosen amount of anode current change, compared to the amount of grid voltage change for the same anode current change.
The symbol is u (it's actually the Greek character for m), and it's called "mu".
That is, using "d" for "amount of change":
dVa/dVg for equal dIa.
Typical values are as low as 2 (6AS7/6080 regulator valve) to 12 (6C4/12AU7 medium-mu triode) to around 100 (6AV6 high-mu triode).
Some special microwave triode have mu values in the 300s.

Was the first amplifying tube a triode?
If by triode, you mean "a three-electrode tube", then yes. You need a source of current into the device, a control electrode, and an "outlet" for the controlled current. Although there were radically different types of construction, all early amplifying tubes were triodes of some kind.
What does a square factor mean?
A factor that is a square number. 16 is a square factor of 32.
What is the rime factor of 37?
If you mean prime factor, it's 37.
Does GCF mean Factor or Fewer?
GCF stands for Greatest Common Factor.
What do you mean by partial safety factor?
The factor of safety for loads is known as partial safety factor. Partial safety factor=Design load/Characteristicload
What are the advantages of using transistor as an switch instead of diode?
1. A transistor *is* a triode- this is the general name for any three-electrode electronic device. 2. Most people understand "triode" to mean a tride vacuum tube/valve. 3. The transistor (i) needs no heated filament/cathode, so it uses much less power than a valve triode, (ii) because of (i), transistors do not "burn out" with age, so they have much longer lifetimes, are much more reliable, and generate much less waste heat, (iii) transistors can operate at much lower power than triode valves, and at much higher frequencies, (iv) transistors can be made much smaller than triodes, by a factor of many tens of thousands, (v) from early on, transistors were much cheaper than triode valves.
What does class D amplification mean?
Class-D amplification is where the amplifiers act as electronic switches.
What does Light Amplification of Stimulated Emission Radiation mean?

What is the abriviations laser?
If you mean what does laser abbreviate it means Light Amplification by Stimulated Emisson of Radiation.
What is the different between positive and negative decibel?
Negative decibels mean damping (loss) and positive decibels mean amplification (gain).
What does superior valve mean in a medical term?
Superior valve means the valve on top.
What does it mean if egr valve is stuck in closed performance position?
The valve has failed.The valve has failed.
Is safety valve and pressure valve mean the same?
yes
What does overhead valve mean?
It's a valve that's over your head
What is the Pressure drop in glove valve?
You mean GLOBE valve and that would depend on the size of the valve and the maker
