本论文主要进行了如下工作：运用绝热定理的方法研究耦合系统混沌态的半经典量子化，发现对于合适选择的零级哈密顿量，经典混沌态和规则态的量子化结果，在绝热近似下有相同的精度。

Under the optimum conditions, the linear range of the method was 0-80 μg/L. The detection limit was 4.58×10^(-7) g /L.The catalytic reaction was the zeroth order one. The apparent activation energy and the reaction rate constant was found to be 96.04 kJ/mol and 3.61×10^(-3)/s, respectively. The sensitivity was increased by 3 times in the presence of surfactant.

In this thesis, we analyze the zeroth order term of eigenpolynomial of linearized matrix, and a necessary condition for diffusion-driven instability of n-species of a reaction-diffusion system is attained by using the Routh-Hurwitz criterion.

本文我们讨论含有n(。23)个物种的反应系统，对系统在无扩散时稳定的平衡态解附近线性化，通过分析线性化矩阵特征多项式的零次项，根据Routh一Hurwitz准则，得到了零次项使系统产生扩散驱动不稳定性的必要条件。

Zeroth Order Ignorance (0OI), the application of already-known information, requires a stable, detailed, and highly repeatable process - basically a streamlined version of the same process that was used when the knowledge was first successfully implemented after being obtained.

零级无知，已经知道信息的应用，需要稳定，详细，和高度可重复的过程－基本上是同样过程的串行，当知识获得了之后就马上实现。

Especially for kw_0≥30, the results coincide with each other verywell. By expanding the exact solution, it can be seen clearly that the zeroth order term is just the paraxial one, so the paraxial approximation field is good enough to replace the exact field when the beam width is large to some extent.

结果表明对于腰宽仅有几倍波长的强聚焦高斯光束，低相速度区仍然存在，并且低相速度区分布的规律与近轴近似场结果在本质上是一致的。

Zeroth Order Ignorance (0OI): Lack of ignorance.
