查询词典 theta

While the standard Airy function, used frequently in the uniform asymptotic formulas for classical orthogonal polynomials, behaves like the exponential function on one side and the trigonometric functions on the other side of an extreme zero,the q-Airy polynomial behaves like the q-Airy function on one side and the q-Theta function on the other side.

在经典正交多项式的一致渐近公式中我们通常要用到Airy函数，这个Airy函数在一个极端零点的一边表现为指数函数，另一边又表现为三角函数。同样地，q-Airy多项式在一边表现为q-Airy函数，另一边又表现为q-Theta函数。

We are concerned with this problem. By combining with the methods of Theta functions and Lambert series, we compute some reciprocal series related to generalized Fibonacci and Lucas numbers.

在本章第二节中，我们将Lambert级数法与Theta函数法结合起来，计算出一些与广义Fibonacci，Lucas数的倒数有关的级数的近似值。

By means of classical analytic method and combinatorial computational technique, such as functional equations, Liouville theorem, series rearrangements, this dissertation investigates the product identities on theta functions.

Liouville"s Theorem on entire functions is proposed as a proving method for theta function identities. Several identities are exemplified, such as the quintuple and septuple product identities; four symmetric difference identities related to the Ramanujan"s congruence modulo 11 on the partition function; as well as two theta function identities on the Rogers-Ramanujan functions G and H.

作者提出利用Liouville定理作为证明theta函数恒等式的基本方法，并以Watson五重积，Hirschhorn七重积恒等式，四个与分拆函数中Ramanujan的模11同余有关的对称差恒等式，以及两个与Rogers-Ramanujan函数G，H有关的theta函数恒等式为范例，论证这种方法的有效性。

In addition, by utilizing Jacobi two square numbers theorem and Lagrange four square numbers theorem and some theta function identities, we also prove the known results of number theory: two triangular number theorem, four triangular number theorem, and the number of representations of a positive integer by various quadratic forms in terms of divisor functions

包括Jacobi二平方数定理，Lagrange四平方数定理等，然后利用这些结果结合几个theta函数恒等式，我们获得了把任意一个正整数表示成两个三角数或四个三角数的和以及其他的二次形式的方法数，这些方法数都是用因子函数来表示的。

In every theta cycle this type of interneuron fired in burst with 3-10 spikes. Their firings incline to the positive peak of theta oscillation.

在每个theta循环周期，这类神经元均呈簇状放电，每一簇大约有3-10个电冲动，且放电的最大概率趋向于在theta节律的波峰放电。

This type of interneuron showed similar firing rates with theta oscillation (10.947±0.658 Hz ) when they were active. In every theta cycle there was only one spike and their firings were not phase-locked to theta oscillation.

在活动时，这类神经元基本维持一与theta节律相近的放电频率(10.947±0.658 Hz)，在每一个theta循环周期里一般只有一个放电，但放电与theta节律间却没有相位锁定关系。
