a) The probability density curves are Gaussian, confirming porosity to be structure-insensitive.
This formula applies only in the case where the inverse power of the spectral density curve is 2.
These were the other cases where, if the spectral density curve were of a certain inverse power, the analysis in the appendix indicated a possible formula relating these two variables.
After the data have been plotted this way, the fitting constant C along with the dimension of the inverse power of the spectral density curve can be used to characterize the elevation profile for vehicle test purposes.
Factors such as injection speed, injection temperature and mold temperature produced predictable changes in the crosslink density curves generated by the system.
