植物的

Based on examinations of type specimens housed at PE, lectotypes for five names of Chinese taxa in Fagaceae, Papaveraceae, Capparidaceae and Cruciferae are here designated under Article 8.1, 9.9, 9.10 and 37.2, Recommendation 9A.2 and 9A.3 of the International Code of Botanical Nomenclature, because the types were respectively indicated by reference to a gathering that consists of more than one specimen, or more than one gathering were simultaneously designated, without indicating the type in the protologue.

摘要查阅保存于中国科学院植物研究所标本馆的壳斗科、罂粟科、山柑科和十字花科植物的模式标本时，发现有5个植物名称的模式均多于1份标本，或同时引证1号以上的标本而没指定模式，根据《国际植物命名法规》规则8.1、9.9、9.10和37.2，以及辅则9A.2和9A.3的精神，对这些名称做出后选模式指定。关键词壳斗科；罂粟科；山柑科；十字花科；后选模式

In the respect of plant geography, combining with the situation that plaeogeography, fossils of cycads, present the diversity of cycads of China and the evolutionary process of cycads, think that southwestern region of China are distribution center of plants of Cycadaceae and the originated center.

在地理分布方面，结合古地理、古苏铁植物化石的情况及现代中国苏铁科植物的多样性及苏铁科植物的演化过程等方面分析，认为中国的西南地区为苏铁科植物的分布中心，也是起源中心。

Three kinds of hydrophytes, Veliveria zizanioides Nash, Eichhornia crassipes, and Oenanthe javanica DC. were used to investigate enrichment ability of nitrogen and phosphor at the different TN levels with TP constant. It revealed the absorption ability of aquatic plants and purification ability of aquatic macrophytes-rhizosphere microorganisms system respectively in aquatic macrophytes-microorganism system for water purification.

研究了不同TN浓度下香根草、水葫芦、水芹等水生植物－微生物系统富集N、P的能力，揭示了水生植物－微生物系统中水生植物的吸收作用和根际微生物系统对净化水质的作用，对水生植物根际微生物系统相应微生物的数量做了定量的统计。

In a word, the greening of residential area should take advantage of the plants' purify, beautification and protective function, making people's daily life every detail and greening in close contact with each other,let residental area is no longer drab, but a complete green ecological system, various kinds of color is the plant, flowering plants, shade plants to create landscape, it is pleasant to create a harmonious natural inhabitants of ecological living space.

总之，居住区绿化要充分发挥植物的净化、美化及防护功能，使人们日常生活中每一细节与绿化密切接触，让居住区绿化不再是一两块单调的绿地，而是一个完整的绿地生态系统，是用各类色叶植物、开花植物、遮阴植物等营造出的怡人景观，是为居民创造的一个和谐自然的生态居住空间。

With the enhancement of CO_2, photosynthesis rate and water use efficiency tend to be increased, but transpiration, respiration rate and stomatic conductance tend to be decreased.

CO2是植物生长的源，在植物的整个生育期中充当着重要的角色，参与植物体内的一系列生化反应，对植物的生长产生直接影响。

Not only the city afforests requests the city to be green, moreover must be artistic, thus the affor

城市绿化不但要求城市绿起来，而且要美观，因而绿化植物的配置就显得十分重要，与环境在生态适应性上要统一，又要体现植物个体与群体的形态美、色彩美和意境美，充分利用植物的形体、线条、色彩进行构图，通过植物的季相及生命周期的变化达到预期的景观效果。

This is a collaborate organization which dedicated to plant biodiversity research. A major function of the Centre is to document the biological diversity of the Australian environment through establishing the taxonomic identity and relationships of native plants, their geographical distribution, and their ecological relationships. These studies primarily concentrate on significant national plant groups such as eucalypts, orchids, grasses, grevilleas, mosses, rainforest laurels and the citrus family.

这是一个开展植物生物多样性方面研究的协作组织，该组织的主要功能是通过确定本土植物的分类特性及其相互间关系，地理分布和生态联系，记录、研究澳大利亚环境范围内的生物多样性，研究对象主要集中于该国的重要植物种群，如桉树、兰花、草类、银桦属、苔藓、雨林月桂和柑橘类植物。

One such novel idea is that of inserting into the chromosomes of plants discrete genes that are not a part of the plants' natural constit ution:specifically,the idea of inserting into nonleguminous plants the genes,if they can be identified and isolated,that fit the leguminous plant s to be hosts for nitrogen-fixing bacteria.

复杂修饰+插入+省略+倒装）这其中的一个新颖思想就是，在植物的染色体内注入并非是该植物自然构造一个部分的那些不相关联的因基：具体而言，这一思想是，在非豆科植物内注入这样一些基因，倘若这些基因可被辨识出来并被分离开来，而这些基因业已使豆科植物宜于充当那些具备固氮作用的细菌的寄主。

In this study, three PAEs compounds, that is diethyl phthalate, di-n-butyl phthalate and bis(2-ethylhexyl) phthalate, were selected as objective compounds, and pot experiments of different plants (including maizes and forage plants) with different remediation measures in glasshouse were carried out and GC/MS analysis of PAEs were used to investigate the remediation effect of soils contaminated by PAEs by different plants and remediation measures.

本论文选取3种PAEs化合物（DEP、DBP和DEHP），以气相色谱/质谱联机检测技术，通过盆栽试验研究不同植物对PAEs化合物的降解差异，并在筛选对PAEs修复能力较强的植物的基础上，探讨其在不同条件下对PAEs污染土壤的植物修复效果，为PAEs污染土壤的植物修复提供理论依据和实用技术。

The students can grasp the methods and skills of using the microscope, cutting into slices bare-handed, loading slice, dying, biological drawing, know the basic knowledge and skill of observing, dissecting, describing, searching, determining of plants, etc.

通过本课程的教学使学生掌握显微镜的使用及徒手切片、装片、染色、生物绘图等方法和技术；掌握观察、解剖、描述、检索、鉴定植物的基本知识和技能，学习采集、制作植物标本的方法，了解植物生态、群落的一般知识及植物在生态系统中的地位和作用；通过实验使学生进一步理解掌握理论知识，了解国内外植物学实验的新技术、新方法。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
