The Vietnamese material is dearly distinguished from the examined holotype (AMNH 8365)and paratypes (AMNH 10316, 10307) of Schistura fasciolata by the pelvic-fin origin situated below unbranched or first branched dorsal-fin ray (vs. pelvic-fin origin dearly in front of dorsal-fin origin in S.fasciolata).

越南采集的标本和横纹南鳅的模式标本（AMNH 8365）和副模式标本（AMNH 10316， 10307）有明显的差别，腹鳍起点位于不分支鳍条或第一分背鳍枝鳍的下方（vs S.fasciolata的腹鳍起点明显在背鳍起点的前方）。

The SARS virus origin which obviously differs from the theory of out space origin and the theory of wildlife origin was theoretically discussed based on principles of pollution evolution ecology,pathogenesis and infectant characteristics of SARS,and some relevant experimental evidence. It emphasizes on the fact that increasingly combined pollution in China provides a substantial basis for virus evolution.

针对当前广为流传的SARS病毒"太空起源说"和"野生动物来源说"两种理论，本文根据污染进化生态学原理和SARS病毒发病传染特征，以有关实验结果为科学依据，阐述了SARS病毒的起源问题，指出：我国当前环境日益严重的复合污染为SARS致病病毒的产生提供了适宜的外部生态条件和物质基础，SARS致病病毒可能起源于多个病毒的基因重组或融合，更可能是一种来自于感冒病毒进化而形成的超级感冒病毒。

Conversely, a point P to the right of the origin, whose distance from the origin is d units, shall have as its corresponding real number the positive real number d and, similarly, if Q is a point d units to the left of the origin , then Q shall have as its corresponding real number the negative real number –d.

Conversely，在起源右边的点P，从起源的距离是d单位，将有作为它对应的实数正面实数d和，同样地，如果Q是点d单位在起源左边，然后Q将有作为它对应的实数消极实数–d。

The central issue of this paper is the study of DNA-binding proteins interacted with DNA replication origin. The paper presented here includes there parts which are related as well as independent of each other:(1). Identification and partially purification of DNA-binding proteins interacted with eukaryotic DNA replication origin;(2) Specific binding of Hela cell proteins to Samian Virus 40 replication origin with the cruciform structure (Stem-Loop structure);(3) The study of DNA-binding protein as a tumor marker.

Take for example the certification of origin protection of Xiaoshan green plum, the paper expounds that the construction of a place-of-origin geological model of farm crops based on agrogeological environmental survey may provide a scientific basis for the definition of the region of origin and also basic data for enlarging the planting area of high quality crops and adjusting the agricultural structure.

结合萧山大青梅原产地保护认证的实践，阐明了通过农业地质环境调查建立农作物的原产地地质模型，可为原产地的地域划定提供科学依据，也可为扩大优质农作物的种植面积和调整农业产业结构提供基础资料。

The available operation range in clivus and anterior cranial base by transsphenoidal opproach was also observed during the operation under the help of neuronavigational pointer. Forty-one patients underwent sublabial, transseptal, transsphenoidal approach to the pituitary region guided by Surgical Microscope Navigation was studied. The piriform aperture was 27. 2mm±3. 1 , the origin of inferior nasal concha 30mm±4. 1, the origin of middle nasal concha 27. 9mm±4. 3. These data are important for transsphenoidal approach, because the piriform aperture and the origin of both inferior and middle nasal conchas restricted the opening width of the Hardy specula. If any distance of these bony structures was much less than the mean one, may cause inadequate opening of the specula blade and resulting dissatisfied operative field. Microadenomas or cystic tumors perhaps can be operated even in a narrow exposure, but large or giant solid adenomas may need a proper evaluation including changing the operative approach or performing a bilateral submucous inferior conchotomy or posterior ethmoidectomy firstly.

手术中还利用CT导航系统观察棒研究了经口—鼻蝶窦入路在斜坡区和前颅底能够达到的实际有效操作范围，为扩大经蝶窦入路手术在斜坡区和前颅底的应用奠定基础，在国内外尚未见同类报道。41例垂体瘤患者梨状孔平均宽度27.2mm±3.1，下鼻甲根部附着处间距30mm±4.1，中鼻甲根部附着处间距27.9mm±4.3，这是经口—鼻蝶窦入路手术中，对Hardy双瓣鼻窥器张开限制的主要骨性结构，若患者这些径线值明显小于平均值，则可能因为鼻窥器打开不充分而影响手术暴露，当然对于垂体微腺瘤和以囊变为主的垂体瘤可能影响不大，但对于大和巨大垂体瘤必须要有充分的准备，包括评估是否改用其他入路，或先行鼻甲切除再行经蝶手术。

Four chapters in the first volume, including "The Origin of Movement","Thinking of Effort","Movement Space" and "To Find Body", develop the theoretical structures of body language in western modern dance, analyze elements of movements and their semantic characters, reveal the conceptual transformation in the science of modern human movements and science of body language, and discover the re-interpretation through modern dance about the essence of movement and space and time of movement Another four chapters in the second volume including "Feminized Body""Masculine Body""Sex-confused Body" and "Body's Origin", study respectively features of body language in the field of ballet, modern dance and post-modern dance, provide a chronicle embodying the form variation of body language through lineal comparison, and exposit spiritual pursuit and value preference of modern choreographers and their relationship with history and culture. Therefore, effective body strategy of "Back to Body's Origin" in today's human existence is offered and teaches us how to keep our own national culture in the times of cultural globalization and integration.
