The leaf epidermis structures of 6 species of Rhododendron had been observed under LM and SEM. The results show that all share together common features as follows: the leaf blades are typical back-abdomen bifacial types, the upper epidermis are formed by two or three layer bigger cells which inside layer cell is bigger than outside one, and the upper epidermis are covered with thicker cuticle.

General characteristics of cells, its chemical constituents ( protein, nucleic acid, carbohydrate, lipid), cell structure , cell cycle, cell division, four kinds of tissues (epithelial, connective, muscular, and nervous), organ, ten organ systems (dermal, skeletal, muscular, digestive, respiratory, circulatory, excretory, endosecretory, nervous, and reproductive).

细胞的一般特征，细胞的化学组成(蛋白质，核酸，糖类，脂类)，细胞的结构，细胞周期，细胞分裂(无丝分裂，有丝分裂，减数分裂)，四大组织(上皮组织，结缔组织，肌肉组织，神经组织)，器官，十大系统(皮肤系统、骨骼系统、肌肉系统、消化系统、呼吸系统、循环系统、排泄系统、内分泌系统、神经系统和生殖系统)。

It is to think network advertisement at or surpass traditional advertisement, cheap Mo place does not go to charge; 2 it is Shu of one-sided pursuit impression, impressional Shu is one of levels that measure network advertisement effect, but sometimes one Ge visits Ke Zai a website can produce ten Ge even Shu of two Ge impression; San is to feel integrated big website is straighter than hanging down effect of advertisement of site of is good, but accept the product ad with apparent feature of numerous target group to great majority, this kind of choice is unwise.

一是以为网络广告等于或胜过传统广告，费用低廉无所不到；二是片面追求印象数，印象数是衡量网络广告效果的标准之一，但有时一个访客在一家网站就可以产生十几个甚至二十几个印象数；三是以为综合大网站比垂直站点广告效果好，但对于大多数受众目标群体特征明显的产品广告，这种选择是不明智的。

Objective To determine the normal and variation of the acetabular labra in asymptomatic hips by means of a radial-sequence MR imaging technique with FLASH-2D sequence, and to study the relationship between the shape and signal of the labrum with patient's age in corresponding the segment of the labrum.

目的 采用放射状扫描方法及FLASH-2D序列显示各部位髋臼唇的形态信号，观察不同年龄组及不同解剖部位无症状髋臼唇的MRI特征，研究其形态及信号与年龄及解剖部位的相关性。

Being fluent in a mother tongue allows one to develop metalinguistic skills (i.e., unconscious knowledge of language properties and fundamental rules) that can be transferred onto subsequent languages.

流利地使用母语能够使人发展元语言学的技能（如关于语言特征和基本规则的无意识知识），而这些技能有助于其他语言的学习和掌握。

The results showed that bulb height and flower size of 'Large Copper' were least, with longest white short soft hair on stem. Obvious characteristics of 'Toronto' were nacarat and lackluster membranous bulb scales, leaves with rufous stripe and base of perianth shape and colour. Obvious characteristic of 'Pink Impression' were taller plantlet, bigger flower, taller and wider leaves and edge of leaves with short hair.

结果表明：品种Large Copper的种球高度和花径均最小，茎上白色柔毛最长；品种Toronto的显著特征是种球的膜质鳞片为桔红色，无光泽，叶片上有红褐色条纹，花被片基部为黑色舌形；品种Pink Impression植株高，花大，叶片长而宽，叶缘有短毛。

objective to explore some ct characteristics and risk factors for traumatic chronic bilateral subdural hematoma.methods a total of 52 patients with chronic subdural hematoma were reviewed.some ct characteristics of bcsdh were studied first.then,the risk factors for bcsdh were determined by logistic regression model from the following variates: age,gender,prediagnostic duration,site for injury force,coma experience and ct showing after injury.results bcsdh was observed in 44.2% of 52 patients with csdh.

作者单位：第三军医大学大坪医院野战外科研究所神经外科，重庆 400042 目的探讨创伤性双侧慢性硬膜下血肿的ct特征及危险因素。方法回顾有随访资料的创伤性慢性硬膜下血肿52例。先研究其ct表现，然后采用多因素logistic回归分析从以下变量中，如年龄、性别、伤后&潜伏&时间、受伤着力部位、受伤时有无昏迷经过、伤时ct表现等确定bcsdh发生的影响因素。

Secondly, interpret the water-bearing status of drainage-base substance fromTM,according to the water-bearing spectral features,using GIS and RS technologies,based on thesurveying hydrologic data,and build up the projectional mathematical model of the Karstdrainage low-flow resource, in order to solve the calculation of the amount of low-flow resourcesin no documents and data regions.

二是以实测的水文数据为基础，利用 GIS 和 RS 技术，根据赋水光谱特征，从 TM 影像判读枯季流域下垫面物质赋水状况，建立喀斯特流域枯水资源预测的数学模型，用于解决无资料、无数据地区枯水资源量的计算。

SO3 is fixed in ashes at 850~900℃, and it exists in Ⅱ-CaSO4 and has different solubility with the natural anhydrite and the plaster calcined at 400℃. It is the first time to prove that the particles of f-CaO is coated withⅡ-CaSO4 by investigating the process of forming f-CaO, the microstructure, spathic type and optic parameter and the hydrating process.

首次从f-CaO的形成过程、颗粒微观结构、晶型和光学参数以及水化历程等方面证明了f-CaO颗粒被固硫产物无水硫酸钙包裹的颗粒特征，f-CaO颗粒被Ⅱ-CaSO4包裹使其水化速度减慢和活性较低；SO3以Ⅱ-CaSO4形态存在和f-CaO颗粒被Ⅱ-CaSO4包裹均对流化床燃煤固硫渣的活性和体积稳定性产生不利影响。

This one mode pays close attention to network credence foundation of the businessman very much.

这一模式非常关注商人的网络信用基础。
