积分元

At present, the common numerical methods are finite difference, finite element , boundary element, integration equation and transmission line method.

目前，解决这类问题的数值方法主要有有限差分法、有限元法、边界元法、积分方程法、传输线法等。

In the course of these derivation, the orbital integrations and the summations over spin are completed and are presented3j, 6j, 9j symbols and the radial matrix elements.

在这些推导中，完成了所有角向积分和自旋求和计算，相应的结果用3j、6j、9j符号和待定的径向矩阵元来表示。

In this Thesis, we designed and implemented an oversampling multi-bit delta-sigma modulator.

在这篇论文中，我们设计并以交换电容电路实现了一个多位元的三角积分调变器。

No clear conclusions can be made about the predictie alidity of specific measures, they found, except for criteria for the underuse of drugs for cardioascular disease.

除了心血管病不合理用药标准外，对于特定评价方法的预测效度没有明确的结论。

The third and last is that almost all of them, being infinite in number, have been impostures, and by idle and crafty brains merely contrived and feigned after the event past.

第三、即最后一点是：几乎所有这些不胜枚举的预言都是欺人之谈，都是在事件过后由无聊而狡猾的脑筋推测与凭空捏造的。
