Themain contents of this dissertation are as follows:(1) The quality analytiedal results of chitosan are as follows: water for 15.205%;degree of deacetylation 92.671%; the weight average relative molecular weight ofchitosan 195900; the viscosity average relative molecular weight of chitosan 194100;and the decomposing temperature 298℃. The infrared ray IR spectra of chitosanshows that the feature-absorbing band of chitosan amido was 1601cm~(-1), that ofβ-indican bond was 986cm~(-1). The results of the X-ray diffraction of chitosan indicatesthat its degree of deacetylation and degree of crystal are both big.

本文的主要内容如下：(1)对壳聚糖的质量进行分析，其水份为15.205％，脱乙酰度为92.671％，重均分子量为195900，黏均分子量为194100，分解温度为298℃，壳聚糖的红外光谱表明，壳聚糖—NH_2的特征吸收峰为1601cm~(-1)，β-糖苷键的特征吸收峰为986cm~(-1)，壳聚糖的X-衍射图表明壳聚糖原料的脱乙酰度和结晶度均较大。

According to the X-ray dose intensity, the parameters of the current detect circuit can be flexibly changed, so it can detect different energy levels X-ray.

这种采集方法可根据X射线的剂量强度，灵活的改变电流检测电路的参数，因此适用于不同能量级的X射线的采集。

Inthis paper, we collect 119 γ-ray-loud Blazar 97 flat spectrum radioquasars (FSRQs and 22 BL Lacertae objects,and investigaterespectively the correlation between the γ-ray emission (maximum,minimum, and average data) at 1GeV and the radio emission at 8.4GHz bydiscrete correlation function method.

收集了119颗有γ射线噪的Blazar天体样品(97个平谱射电类星体和22个BL Lac天体)，用离散相关函数方法分析了1GeVγ射线辐射流量(最大值、最小值和平均值)与8.4GHz射电辐射流量之间的相关性。

Furthermore, a strong linear correlation exists between radio-luminosity and γ-ray lurninosity〓 The possible upper limit relation suggests that the contribution to γ-ray background of AGNs may be less than other authors' prediction.

另外，光度——光度之间存在显著的线性相关〓可能的上限关系表明AGNs对γ-ray背景的整体贡献比以前认为的要少。

Abstract］ objective to study the knowledge of the imaging manifestation of x-ray and ct in peripheral small lung cancer.methods to collect twenty cases with no symptom in early time diagnosed by clinic and to retrospectively analyze their imaging features.results x-ray appeared patch,small node.ct appeared patch,small node,light lobulation,peripheral vessel convergence,pleural indentation sign.most of the diameter was 1.5 to 2 cm,with no mediastinum and pulmonary hilar lymph nodes diversion.furthermore the clinical symptom was not obviously.conclusion to be familiar and handling the sign mentioned above is the key to boost the diagnosis of small peripheral lung cancer.

目的 探讨周围型小肺癌的x线、ct影像学表现。方法收集临床和病理证实的早期无症状肺癌20例，对其影像学进行回顾分析。结果本组早期肺癌x线为斑片状、小结节状。ct表现为斑片状、小结节状、轻度分叶状肿块，小毛刺、血管集束征、胸膜凹陷征，大多直径在1.5～2 cm。无纵隔淋巴及肺门转移，且临床症状不明显。结论熟悉并掌握上述征象是提高小肺癌早期诊断率的关键。
