At first, this paper surveys nonlinear control and the applications of neural networks in control respectively. Then it studies definitions, mathematical descriptions and conditions of invertibility for nonlinear systems, which are used to analyze the feasibility of inverse system control method. Conclusions about the feasibility of inverse control and the realizability of αth-order inverse systems in engineering are achieved. Furthermore, this paper discusses the feasibility, structure and identification of neural network αth-order inverse system for general single-input single-output continuous or discrete nonlinear systems and various composite control methods based on the αth-order inverse. At last, as a part work of an actual project, this paper focuses on the design of neural network αth-order inverse control method for thyristor controlled series compensation in power systems and its effect in improving the stability of power systems.

本文首先分别概述非线性系统的控制与人工神经网络在控制中的应用；然后研究非线性系统各种可逆性的定义、数学描述及可逆性条件，并用于分析逆系统控制方法的可行性，得出有关逆系统控制方法可行性的结论，阐明一般情况下α阶逆系统才工程可实现；接着本文针对一般单输入单输出连续、离散非线性系统，研究神经网络α阶逆系统的可行性、结构与辨识以及基于神经网络α阶逆系统的各种复合控制方法，并给出应用例子；最后本文结合实际项目，针对采用可控串补的电力系统，设计神经网络α阶逆系统控制方法，研究其对提高电力系统稳定性的作用。

To explore the microdissection of the cerebellopontine angle as well as to study the advantage and disadvantage of the retrosigmoid approach and the retrosigmoid suprameatal approach, the relationship among the facial nerves, inter-medium nerves, anterior inferior cerebellar artery and petrosal vein were studied, and two approaches particularly also were explored from fifteen dry skulls and ten wet skulls, along the approach of RSA and RSSMA.

本研究旨在了解桥小脑角的显微解剖；探讨枕下乙状窦后入路及乙状窦后-内耳道上入路的优缺点。本实验采用15例(30侧)干标本和10例(20侧)湿标本，按照枕下乙状窦后入路和乙状窦后-内耳道上入路的所涉及的解剖区域，解剖观测面神经、中间神经、小脑前下动脉及岩静脉等诸多结构，并对神经外科手术乙状窦后入路及乙状窦后。

Results: Base on the dissection, the rabbits' sciatic nerve was composed of the seventh lumbar nerve and first and second sacral nerves. The sciatic trunk descended in front of the sacroiliac joint and escaped between the sacral bone and ilium, then left the pelvis from the greater sciatic notch. The segment of sciatic trunk which ran between the sacrum and ilium was stable and feasible for localization according to the related bony structures in CT scanning, so it was selected as irradiation target. After high dose of stereotactic radiation, the degeneration and necrosis in nerve fibers could be observed under microscope.
