查询词典 variation of a function

Within this framework we develop a theoretical approach to interpret photoelectron angular distributions in terms of a generalized phase Bessel function which can determine the principal features of the distribution and its variation with laser frequency and intensity.

It includes an optimized curve fitting algorithm based on the least-squares method and a surface lofting algorithm in which a interpolation function is employed to provide a continuous variation of the parameter in one direction over the entire lofted surface.

基于最小二乘法，对截面数据进行均方误差下的精确优化拟合；在曲面蒙面算法中，采用插值函数确定蒙面曲面一个方向的参数。

The variation of flow stress as a function of deformation temperature and strain rate can be described as an exponential expression.A processing map is developed on the basis of hot compressing data and by using the principles of dynamic materia...

实验结果表明在试验参数范围内存在三个特征区域：一个加工安全区：动态再结晶区；一个加工失稳区和一个不适合热加工的低耗散效率区，并根据热加工图对 GH4648合金的热变形工艺进行了初步设计。

The anti-integrable limit theory is much simpler than the KAM theory since it is just obtained as a variation of the standard implicit function theorem.

近年来提出的反可积极限理论是研究完全混沌系统的扰动。

We consider it to be a variation of the sexual function produced by a certain arrest of sexual development.

而那位曾经向佛洛伊德求教的母亲终可替这封不平常的信找到归宿。

This variation is primarily a function of the cutoff leakage current of the CA3080A (a maxi- mum limit of 5nA), the leakage of the storage element, and other extraneous paths.

这种变化主要是截止泄漏的CA3080A（一5nA马克西，妈妈限制电流功能），存储单元的泄漏，以及其他无关的路径。

A group of amorphous CHN films were fabricated successfully by hollow cathode plasma chemical vapor deposition with ammonia, hydrogen and methane as reacting gas. The variation of deposition rate as a function of DC voltage and reactive gas flows were studied, respectively.

Two construction methods for fewer views from limited range—ART and SART are studied, and simulated a physical fields views whose variation of deflection is equal to double-Gauss function, and then reconstructed it, and still analyzed the accuracy of the reconstruction methods.After study and analysis on the theory of ART and SART, and after analysis the properties resulted from their theory root cause, A modified simultaneous algebraic reconstruction method is presented, which is based on ART, this method takes into account both the pixel itself and the pixels close by it which are crossed by the same ray.

论文研究了两种有限投影方向的非轴对称场的CT重建算法——代数重建法和联合代数重建法，并用VC++程序模拟实现了折射率分布为双高斯函数的场的正向投影及重建过程，并对所用算法的重建精度进行了分析。

To overcome the quadratic variation terms of stochastic control and the uncontrollability in chained system, a novel control design procedure is constructively proposed, which involves the introduction of a time-varying technique and the application of quartic Lyapunov function.
