Methods: According to the mechanism of cough reflex, the c-fibres's role in the respiratory system, and the principle of isosterism. Here, a peripheral antitussive LD was regarded as a lead compound. Amino functional groups, as substituents at the 1-hydroxy group of the racemate of LD, were introduced into the structure of the molecule. These novel compounds were confirmed by 1H-NMR, MS spectrum. Their antitussive activities were studied on mice in sequential method. The EDT50, the stimulating time that caused cough by NH3 on half of mice, were measured. Then could caculated the ratio R between the EDT50 of the treated groups and control group.

In degraded PSM matching classification, errors modification method of degraded PSM is presented and the matching tensor of every canonical scattering centers is given. In Chapter 4, the theory of wideband millimeter-wave radar target identification is introduced. It is indicated that, for HR radar target identification, description of temoral relations among features and pattern recogntion adaptive to variation of target angles are of key importance. A rule-based pattern recogniton method of sequential reasoning is proposed, which uses a series of rules to describe relations of features variation caused by target angles variation and has the advantages of adaption to unrandom variation and false probability control in classification over traditional statistical pattern recognitiop method. Feature extraction is crucial step in target identification. In range profiles identification application, features are extracted by means of range domain pre-processing algorithm, spacial and amplitude visual computation directly from range profiles and transform algorithm based on range profiles. Visual or transformed features are either sufficiently convinced or necessarily convinced and both of them are effective and robust to range profiles identification.

在第四章，首先对宽带毫米波体制背景下目标识别方法的一些特点进行了阐述并指出，在毫米波雷达目标识别中，特征之间动态关系的描述以及能适应目标姿态角变化的模式识别方法的研究乃是要解决的关键问题；进而提出了一种基于规则库的序贯推理模式识别新方法，在这种方法的研究中，主要包括序贯推理规则库的规则排列与特征选用顺序以及规则库的收敛等问题；这种方法克服了传统的统计模式识别方法特征利用效率不高、难以适应特征值的非随机性变化的缺点，把姿态角变化所引起的特征的变化用一系列规则加以表示，其优点是能适应特征值的非随机性动态变化，并能控制分类过程中的差错概率α；特征抽取是目标识别中的关键步骤，在基于目标距离像的特征抽取方法研究中，提出了距离空间域的预处理算法、距离空间域与幅度域的直观特征抽取方法以及基于目标距离像变换分析的特征抽取方法。

Methods One hundred and twentythree patients with severe pneumonia were divied into two groups,the second level antibiotics were used in control group untill children cured;sequential antibiotic therapy was adopted in observation group:the second level antibiotics were used first of all,after the complications were controled for 1～3 days,the first level antibiotics were used until children cured.

123例重症肺炎患儿分为2组，对照组在第2级选用抗菌谱宽、耐酶的抗生素，应用到患儿痊愈；观察组采用抗生素序贯疗法，首先在第2级选择抗生素，在重症肺炎的并发症控制后1～3 d，再在第1级中选择抗菌谱窄或不耐酶抗生素，直至痊愈。

With the rapid development of our country's photochemistry industry, the liquified petroleum gas is widely used. However, because of its unique flammable, explosive, virulent physic-chemical properties, it causes a series of burning, detonating accident which has occurred in domestic and foreign, which has caused the giant personnel casualty and property damage. Thus, it has been bad influence to the society. Therefore, it is necessary for the liquified petroleum gas store place to carry on the safety assessment and go on the grave accident sequential analysis research, regarding the effective science forecast, prevention and control significant accident occurrence, so it can reduce or avoid this kind of disaster accidents as far as possible, which has the important theory value and the practice significance for guarantee the liquified petroleum gas store place's safe operation.

随着我国石油化学工业的迅速发展，以及液化石油气的广泛使用，其特有的易燃、易爆、有毒的物理化学性质以及在国内外发生的一系列燃烧、爆炸等事故造成巨大的人员伤亡和财产损失，造成了不良的社会影响，因此，有必要对液化石油气储存场所进行安全评价和重大事故后果的分析研究，对于有效科学预测、预防、控制重大事故的发生，减少或尽量避免此类灾难事故的发生，确保液化石油气储存场所的安全运行，具有重要的理论价值和实践意义。
