The superficial microvascular networks were sparser, while the subpleural microvascular networks were denser. The superficial blood vessels and the interlobular blood vessels were mutual transitional, and the anastomosing between the superficial blood vessels with the subpleural vessels. According to the branching sequence of the subpleural arteriole, it could be divided into the arteriole, terminal arteriole, precapillary arteriole and capillary in turn. The subpleural capillary networks were mainly web-like, while small holes were also found on the cast. The honeycomb vascular networks were various in size and form at a low magnification. The outline of alveolus, alveolar sac, alveolar duct and respiratory bronchiole and terminal bronchiole, made of microvascular networks, could be found in the cut surface.

胸膜面浅层的微血管网稀疏，深层的胸膜下微血管网致密；胸膜面浅层的微血管与小叶间隔的微血管之间相互移行，与胸膜下微血管之间形成吻合连接；根据胸膜下微动脉连续分支的顺序，常可将其分为微动脉、终末微动脉、毛细血管前微动脉和毛细血管四级；胸膜下毛细血管网主要以网络状的形式存在，但在铸型上均可见数量不等的"小孔状"结构；低倍镜下肺实质内微血管网呈现大小不等、形态各异的蜂窝状结构，可以见到由微血管网构成了肺泡、肺泡囊、肺泡管和呼吸性细支气管以及终末细支气管等结构的轮廓。

The ecological functions of arbuscular mycorrhizal fungi in natural and agroecosystem was greatly concerned in recent decades.

泡囊丛枝状菌根真菌(Arbuscular Mycorrhizal Fungi，AMF)对植物营养吸收和对重金属污染的土壤的生态恢复功能是近年来人们关注的热点问题，有关AMF对植物多样性的影响及对被Pb污染土壤的修复的研究已有了较多的报道。

The results by invert embedding TEM showed that higher invasive CCL229cells had vast of ER,which distributed throughout cytosol especially largeamount of vesicle-like and flatten cisternal rER in pseudopodia or cell processesand membranous flow-like structure from perinuclear region to pseudopodia,and less Golgi complex.

倒置包埋法常规透射电镜对人大肠癌细胞的超微结构观察结果显示，高侵袭力的CCL229细胞中内质网数量较多并呈全细胞分布，尤其在细胞伸出的众多伪足中含有丰富的小泡状和扁平囊样粗面ER结构，而且观察到由小泡形成的&膜流样&结构从核周一直深入到伪足中，但细胞中高尔基器少见。

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。

The Filicales is much the largest living group of ferns, and they normally have large spirally arranged leaflike fronds derived from lateral branches of the main axis, some or all of which bear sporangia on their margins or undersurfaces.

薄囊蕨纲是现存蕨类植物中数量最多的一个类群，他们通常具有很大的、螺旋状排列的、从主轴的侧枝上形成的叶（巨型叶 MEGAPHYLIS ），其中一部分或绝大多数都是在叶边缘或背面产生孢子囊群。

A unisexual reproductive structure of gymnospermous plants such as conifers and cycads, typically consisting of a central axis around which there are scaly, overlapping, spirally arranged sporophylls that develop pollen-bearing sacs or naked ovules or seeds.

球果单性裸子植物的生殖器，例如针叶树和铁树目植物，一般由覆满鳞片和褶皱的中心轴构成，长螺旋状排列的孢子叶，孢子叶最终成为花粉囊或裸露的孢子或种子

Especially, the role of the lagena in birds'nervous systemn is of much interest.The macula lagena in birds is located at the apical end of the cochlea and contains many tiny otoliths.

瓶状囊进化地位的特殊性引起了研究者们极大的关注，而对于它在鸟类神经系统中究竟起怎样的作用更是人们所关心的问题。

The characteristic in liquid culture of the purified strains were described, and the relation between the characteristic and the taxonomic traits was researched for the first time. The two groups of Myxobacteria differentiated according to the shape character of the myxospores and vegetative cells had different characteristic in liquid culture.

对纯化菌株的液体培养特征进行了描述，并首次依据初步分类鉴定结果探索了液体特征与分类地位之间的关系，即依据营养细胞和粘孢子形态将粘细菌划分成的两大类型中，第一类型(包括粘球菌属等7个属)的菌株在液体培养基中通常形成片状或絮状，而第二类型(包括单囊菌属等5个属)的菌株则主要呈现球形。

Materials and Methods The triphasic dynamic enhanced CT findings of 52 patients with renal cell carcinoma were reviewed.
