Single age variable stock volume growth model had low coefficientofdetermination, but it was improved a lot by introducing site index and stand density index in reparameterization.
The precondition of the acceleration testing method is the determinationof the train resistance, rotary mass coefficient and train mass. The crucial test is measurement of train acceleration.
