查询词典 algebraic fraction

By taking the effects of Ge fraction and strain on the energy band structure and effective masses into account, the analytical model of the effective densities of states of the conduction and valence bands are proposed, and the temperature and Ge fraction dependence of the effective densities of states are also studied. Following this, the temperature and Ge fraction dependence of intrinsic carrier concentration in strained SiGe layers are analytically calculated. Furthermore, carder freezeout effect and the minority carrier trapping effect of the shallow-level compensated imputities in strained SiGe layers at low temperatures are investigated.

Aiming at OQL, we treated type as monoid (collection monoid and primitive monoid), and used monoid comprehension as OQL's intermediate representation. Therefore we can merge the rewrite rules for a number of collection types, then employ monoid comprehension in defining algebraic operators, as cut out the limit that in relational algebra/calculus algebraic operators are only for set.
