selectivity factor造句

In contrast, in order to get good ee's and yield of the product, very high selectivity factors are necessary.
A rational elliptic function of degree " n " in " x " with selectivity factor ? is generally defined as:
For example, with a selectivity factor of 10, ee3 above approximately 80 % is unattainable, and significantly lower ee3 values are obtained for more realistic conversions.
For example, with a selectivity factor of just 10, 99 % ee is possible with approximately 70 % conversion, resulting in a yield of about 30 %.
Rational elliptic functions are identified by a positive integer order " n " and include a parameter & xi; & ge; 1 called the "'selectivity factor " '.
It's difficult to find selectivity factor in a sentence. 用selectivity factor造句挺难的

For an elliptic filter, it happens that, for a given order, there exists a relationship between the ripple factor and selectivity factor which simultaneously minimizes the Q-factor of all poles in the transfer function:
