为了进一步探讨CPZ白内障的发生机制，本文采用体外大鼠晶体器官培养和兔晶体上皮细胞培养进行了以下四方面研究

The macrofossil records indicate that, in company with the notable climate and environmental changes, the multicellu-lar metazoans and metaphytes experienced a series of important biological evolutionary incidents in this period, such as the organ and form differentiations, the growth innovations and the further diversification of biological structures and functions.

宏体化石的记录表明在这一时期伴随着显著的气候和环境变化，发生了一系列重要的生物演化事件，多细胞的宏观后生动、植物普遍出现了组织分化，器官形成和发育创新，以及生物结构和功能的进一步复杂多样化。

It was thought that these variations took place at the stage of forming flower organ subregions, and could not be interpreted by "ABC model" for flower organ development, nor by the advanced "ABCD model" and "ABCDE model".

分析认为：韭兰的花形变异发生在花亚区的形成期，不能用花器官发育的&ABC模型&以及由&ABC模型&为基础发展而来的&ABCD模型&和&ABCDE模型&解释。

The two can cause ultrastructural pathogenesis widely in many organs and tissues such as hepar, pancreas, lien, ren, pulmo, cerebral, cerebellum, cor, muscular and so on, of them ,caused by i~olates YG97 and Y98 more obvious in epithelial cells of digestive tract and unobvious in epithelial cells of respiratory tract ,but ultrastructural pathogenesis caused by NDV strain F48E8 ,more obvious and more serious in glandularis and muscularis ventriaculi and in epithelial cells of respiratory tract .

将鹅源分离株YG_(97)、鸡源分离株Y_(98)和NDV强毒株F_(48)E_8感染SPF鸡，运用扫描电镜和透射电镜观察该二株病毒对机体细胞的影响，结果显示三株禽副粘病毒均引起机体肝、胰、脾、肾、肺、小脑、大脑、心和肌肉等实质器官组织细胞的超微病变，其中YG_(97)和Y_(98)引起消化道粘膜上皮细胞发生微绒毛脱落、纤毛脱落、分泌颗粒增多、细胞游离面破溃等显著的超微病变，引起气管粘膜上皮细胞的不显著超微病变；F_(48)E_8强毒株引起胃粘膜显著而严重的超微病变；还引起气管粘膜上皮严重的超微病变。

Thefeatures of floral and leaf morphogenesis , the variation of perforation plate of vessels ,the contact types between vessels and xylem parenchyma cells , the organic anatomy ofC .

本文从连香树花和叶的形态发生与发育，导管分子穿孔板韵变异，导管分子间以及导管分子与木质部薄壁组织细胞的接触方式，器官的解剖结构等方面进行了研究。

Bioinformatics is conceptualising biology in terms of molecules(in the sense of Physical chemistry) and applying "informatics techniques"(derived from disciplines such as applied maths, computer science and statistics) to understand and organise the information associated with these molecules, on a large scale.

对序列，结构数据进行定性和定量分析，从中获取基因编码，基因调控，序列-结构-功能关系等理性知识阐明细胞，器官和个体的发生，发育，病变，衰亡的基本规律和时空联系探索生命起源，生物进化，生命本质等重大理论问题，最终建立&生物学周期表&

Fungi are playing a more and more important role in infective diseaes with the increasing of using immunocompromised drugs, organ transplantation and AIDS.

随着免疫抑制剂的大量运用、器官移植的增多、艾滋病等在全球的肆虐，当今世界疾病谱和致病菌正在发生深刻的变化。

Global warming a direct impact on respiratory diseases, allergy and infectious diseases, particularly malaria, lymph nodes filariasis, schistosomiasis and hookworm disease, cholera, meningitis, kala-azar, dengue fever and other infectious diseases will endanger the tropical regions and countries, some At present mainly in tropical areas with the disease may be warming to the spread of mid-latitude regions.

全球增暖直接影响呼吸器官疾病、过敏和传染病，尤其是疟疾、淋巴腺丝虫病、血吸虫病、钩虫病、霍乱、脑膜炎、黑热病、登革热等传染病将危及热带地区和国家，某些目前主要发生在热带地区的疾病可能随着气候变暖向中纬度地区传播。

The absorption and distribution of chromium were studied in ryeusing nutrient culture technique and pot experiment.

采用不同浓度K2CrO4(0，0.4，0.8和1.2 mmol/L)的Hoagland营养液处理黑麦幼苗，测定铬在黑麦体内的亚细胞分布、铬化学形态及不同部位的积累。

By analyzing theory foundation of mathematical morphology in the digital image processing, researching morphology arithmetic of the binary Image, discussing two basic forms for the least structure element: dilation and erosion.

通过分析数学形态学在图像中的理论基础，研究二值图像的形态分析算法，探讨最小结构元素的两种基本形态：膨胀和腐蚀；分析了数学形态学复杂算法的基本原理，把数学形态学的部分并行处理理念引入到家实际应用中。
