Ir expounds the biothermocatalytic transitional zone gas is a special gas formation stage in continuous evolutionary sequence of organic matter, whose exogenic force is temperture and catalysis of clay minerals, at the same time, having decarbxylation, deamination and so on.

论述了过渡带气不受生油成熟门限的限制，它是有机质连续演化序列中的一个特殊成气阶段，其主要的外生营力是温度和粘土矿物催化作用，同时，还有脱羧、脱氨、脱基团作用和芳环的缩聚作用等多途径多方式成烃模式。

Firstly, a quantitative relation about finite deformation and geometrical parameters which exhibit variation of laser spectral image was introduced. And then, particular emphasis was put on some important computer processing steps related to the analysis of spectral image, such as digitizing, segmentation, feature extraction and analytical algorithms. Lastly, some examples about an experiment of a ring subject to large diametral compression were given.

文中首先给出了有限应变和平均整旋角与反映频谱图像变化的几何参数之间的定量关系，然后着重介绍了与频谱图像分析有关的数字化、分割、特征提取和分析算法等重要的图像处理过程，最后给出圆环受径向荷载大变形实验的分析实例。

The synthesis of thiazole ,imiadzole,oxazole and their derivatives were stress introduced.

Using the methodology of radical cyclizations of α-acylamino radicals with acylsilanes to construct pyrrolizidine, indolizidine and quinolizidine skeletons, we were able to synthesize-Lentiginosine,-Epiquinamide,-Swainsonine and other analogous alkaloids.

本论文是延续实验室利用α-醯胺基碳自由基与矽基酮的环化反应来合成吡咯叻咭啶、吲哚叻咭啶和喹叺叻咭啶等骨架的方法，进而企图合成出-Lentiginosine、-Epiquinamide、-Swainsonine及其它类似的生物碱。

We did a lot of experiments, such as separating, cultivating and appraising pathogetic epiphyte, studying physiological character of pathogen, doing manual inoculation, filtrating indoor medicament, and cultivating confrontation in petri dish. The result of study showed the pathogen was Armillaria ostoyae..

通过对病原菌的分离培养与鉴定、病原菌生理学特性研究、人工接种试验、室内药剂筛选、平板对峙拮抗培养等试验的研究结果表明，引起该病的病原菌为奥氏蜜环菌Armillaria ostoyaeRomagn。

NO takes part in transmission of sensation message among capsule of cervical zygapophyseal joints, flave ligament, interspinalia ligament, supraspinal ligament and annulus fibrous of intervertebrale disc.

氧化氮参与人颈椎关节突关节囊、黄韧带、棘间韧带、棘上韧带和椎间盘的纤维环等结构的伤害性感觉信息的传递。

The second exotherm could be ascribed to the relatively compactconformation of individual polystyrene chains; upon heating during DSC scan, phenylring could stack to form some kind of ordered regions inside micro-PS.

而广角X射线衍射以及in situ FTIR等研究证明第二个放热峰则归因于micro-PS特殊的链构象：DSC升温过程中链的疏松构象易于通过苯环的堆积形成局部链段有序化，从而放出热量(大约6.4 J／g)。

In order to avoid misdiagnosis,with the patients who fail to get a clear diagnosis and with liver dysfunction,manifestation of central nervous system,hematuria or anemia,it is essential to check cornea Kayser-Fleischer ring,copper metabolism and require carefully the family history.

为了避免误诊，对诊断不清的具有肝功能损害，或神经系统症状，或血尿，贫血等症状的患者，检查角膜Kayser-Fleischer 环，铜代谢，细致的询问家族史十分重要。

Its synthetic strategies, structural characters, properties and applications to the self-assembly of rotaxane s and catenanes are reviewed.
