查询词典 algebraic cone

Because of special geometry structure of three-cone bit, the top of formation will form a tri-spine well bottom while drilling with three-cone bit the drill string. It is the tri-spine well bottom that leads to the axial harmonic of vibration when the bit revolves a round and the three concavo-convex heave of bit and formation result in one time (1×rpm),two time (2×rpm), three time (3×rpm) turning table speed.

Besides improved transient response, this cone adds stiffness to relieve stress concentrations that may accumulate at the base of the cone under high power and high-pressure applications.

除了改善瞬态响应，这锥增加了刚度，以减轻应力集中，可能在积累的基础下锥高功率和高压力的应用。

非常回到将会倾注了与环氧树脂前粘贴上的严正锥，我不得不放在首位顶端一半的船体上以供参考和然后马克在哪里锥应胶合板。

Suppose G is a finite group, then QG is a semisimple Q-algera, obviously ZG is a Z-order of QG,we denote the maximal Z-order by ?.If G is not abelian, it is not an easy thing to determine г; if G is an abelian group, then QG is isomorphic to the direct sum of a finite number of number fields, and r is the direct sum of these rings of algebraic integers of those number fields, but which elements of QG belong to r is not clear.

设G是一个有限群，那么QG是一个半单代数，ZG是QG的一个Z-序，设Γ是QG的一个极大Z-序，当G是一个非交换群时，Γ的求解是困难的问题；当G是一个交换群时，QG同构于有限多个数域的直和，Γ相应的就是各数域代数整数环的直和，但Γ具体是QG中那些元素不清楚。
