Starting from the classical adsorption theories, the state of research on supercritical adsorption was reviewed in detail.

本文在回顾经典吸附理论的基础上，详细地介绍了超临界吸附的研究现状。

The main content of this dissertation includes: 1. Research on the theory of ultrasonic power supply, introduce its development process. On the basis of these, fix on the scheme of medical ultrasonic low-power supply. 2. According to the principle of modularized design, divide medical ultrasonic low-power supply into four parts. They are power amplify circuit, power control circuit, frequency automatic tracking circuit and matching circuit. Separately research on their theories and design their circuits and necessary programs, especially, effectively resolve the problem tracking the supersonic vibration system with a narrow syntony frequency bandwidth and a high swing. 3. The matching experiments gain good result, and prove that medical ultrasonic low-power supply is entirely up to the mustard on intellectualization, wide band of working frequency, steady output and high efficiency.

本文工作的主要内容包括： 1、研究了超声功率电源的原理，并回顾了它的发展过程，在此基础之上确定本文医用小功率超声电源的设计方案； 2、按照模块化的设计原则，将医用小功率超声电源的设计分解为功率放大电路、功率控制电路、频率自动跟踪电路和匹配电路等四个部分，分别研究了各部分的原理，在此基础之上进行了具体的电路设计和程序设计，尤其是有效地解决了对谐振频率带宽窄振幅高的超声振动系统的频率跟踪问题； 3、通过与超声振动系统的各项配合实验，取得了很好的实验结果，验证了医用小功率超声电源完全满足智能化、工作频带宽、输出功率稳定、输出效率高的设计要求。

The properties and expression of knowledge are discussed in brief and binary and multiple truth expression and inference of knowledge are studied focally. The neural networks which can realized the three valued logic are overviewed. The new idea of uncertain inference based on three valued logic is proposed for the first time The models of neural logic, which can realize three valued logic and uncertain three valued logic inference are proposed, too. The learning algorithm of coefficient of MVL's function based on the canonical realization of MVL network is investigated for the first time and the appropriate algorithm is proposed.

4简要地论述了知识的特征及其表现形式，重点研究了知识的真值二值和多值表示法以及基于知识真值表示法的逻辑推理；通过对目前可实现三值逻辑推理的逻辑神经元及其网络的简要回顾，指出了各自的局限性，首次提出了基于三值逻辑的不定性推理的新概念以及可实现三值逻辑和三值逻辑不定性推理的逻辑神经元模型，同时对基于这种逻辑神经元模型的推理系统的应用领域进行了探索性尝试；另外，首次对基于多值逻辑网络正规实现的多值逻辑函数的系数参数的学习算法进行了研究，并提出了相应的学习算法。

At 47 Twiggy trim and luminous as ever, looks back in amazement at her youth and fame: At sixteen, I was funny, skinny little thing, all eyelashes and legs.

An old comrade in the office, so unhonored as to work for nearly 40 years on the battle line of tax, review he tax career for over these 40 years, expect, leave he work tax all one's life at the post hard soon, he sighs with all sorts of feeling, brimful of tears, the life's joys and sorrows are welled up in mind together," blue love that wrote affectionately on I on workday of his, my heart is forever ",What a deep and eternal loving this is!

局里一位老同志，在税务战线上默默无闻工作了近四十年，回顾他这四十年来的税务生涯，想到即将离开他辛苦工作了一辈子的税务岗位时，他感慨万千，热泪盈眶，酸甜苦辣齐涌心头，在他的工作日誌上深情地写道"蓝色之爱，我心永系"，这是一种多么刻骨铭心的爱恋啊！

For this uncommon disorder, there have been a few reported series with small numbers of patients, and the prognosis and treatment remain uninvestigated. The authors reviewed all nerve biopsies performed over 20 years to identify cases with definite, probable, or possible vasculitis, and they selected 48 patients (30 women and 18 men) meeting clinical criteria for NSVN at presentation. Median follow-up was 63 months.

对这种少见的疾病来说，过去曾有几篇根据少数患者所做的研究报告，但有关其预后与治疗却仍未接受审慎地调查研究，因此这次作者回顾20多年前所做的所有神经切片，并区分为确定病例、极可能病例或血管炎可能病例，然后他们选取符合NSVN临床症状标准的48位患者（30位女性与18位男性），平均追踪63个月。
