Four classes of partition models , empirical models , functional equilibrium models , optimal control models , and source-sink models were reviewed in this paper. The empirical models were widely used with minimal mechanistic assumptions. The function equilibrium models were successful in the simulation of the rootPcanopy ratio at the periods of the vegetative growth , but were poor to simulate portioning among other organs. The optimal control models were suitable for the modeling under the equilibrium state. The source2sink models were the most powerful and mechanistically based models capable of simulating dynamic photoassimilates partitioning between any organs of the plants.

对于同化物分配模型按照经验模型，目的性模型，源汇关系模型进行了总结归纳，分析指出：经验性模型应用最多但机理性差；功能平衡模型在模拟营养生长阶段同化物在条与根之间的分配很成功，但应用于其它器官之间很困难；最优化模型适于模拟平衡态下同化物的分配；源汇关系模型机理性最强，可模拟任何器官间的同化物分配，应用范围最广泛。

Recent advances in the study of institutional innovation and progress of agricultural technology at home and abroad were retrospected.

论文回顾了国内外关于制度创新与农业技术进步的研究动态，阐述了制度及制度创新的一般理论，提出了制度创新与农业技术进步都是促进农业经济增长的独立变量的观点，从制度创新的基础作用、农业技术进步的诱导功能、制度创新与农业技术的发展阶段性特征方面探讨了制度创新与农业技术进步的辨证关系，并建立了一个模型分析论证它们的互动关系。

It fails to grasp the complex ties among these global agents (especially the technology-based oligopolists) and the territorialized relations and conventions upon which they draw and which they often help to construct, and without which they cannot function.

它未能把握这些全球代理商之间复杂关系和领土化关系和它们赖以公约和借鉴他们常常帮助兴建、他们不能无的功能

Halliday ( 2000: 441/516 ) defines "projection" as "the logical-semantic relationship whereby a clause comes to function not as a direct representation of (non-linguistic) experience but as a representation of a representation", and this relationship "is always, in fact, a relationship between processes—between a mental or verbal process on the one hand, and another process of that is mentalized or verbalized by it."

Halliday(2000：441／516)将投射定义为小句复合体中两个小句之间的这样一种逻辑语义关系，其中&一个小句的功能不是对经验的直接表述，而是对表述的表述&，这种关系&总是存在于过程之间——其中一个为思维或言语过程，而另一个过程则被它思维化或言语化了。&

The development of Tianjin Port represents the originality of military function, the derivation of economic function, and the influence of social function. Secondly, it analyses the interaction between Tianjin seaport and the city of Tianjin, from the river port to Zizhulin dock's prosperity and from the eastern movement of center of the city to reform of Tianjin seaport. On this base, it makes a further explanation to the driving effects on the development of Tianjin city, which is caused by development of Tianjin seaport.

其次，分析天津港口与天津城市发展的互动关系，从早期的河港城市到紫竹林码头的繁盛与城市重心东移再到改革开放后的天津港与天津市的互动关系，在此基础上通过港口功能对城市发展拉动作用的理论分析，进一步阐述天津港口历史发展对天津城市发展的拉动作用。

However, whether the degree of tooth wear has something to do with tooth microstructure, how specific occlusal factors affect the development of tooth wear, and what kind of relationship exists between tooth wear and bruxism or TMD, all these are not clear yet.

作为磨损发生的主体，牙齿的内部结构与磨损程度之间是否存在一定的关系，牙齿所构成的特定的个体咬合因素及其生物学力学特征会对磨损产生何种影响，口颌系统两大功能紊乱性疾病——磨牙症、TMD与磨损之间存在何种关系，均尚不清楚。

According to the domain organization, the GGDEF-EAL containing proteins (pfam database, version 17.0) were classified into A and B types. Six hundreds and five of the 621 proteins were in A type, which was also found in the ancient bacteria Aquifex aeolicus VF5 suggesting that this is the ancestor of the GGDEF-EAL proteins. Phylogenetic analysis of GGDEF- and EAL- containing proteins in the genome of V. vulnificus YJ016 revealed that GGDEF-EAL proteins were clustered. Comparative analysis of domain organization of the clads in the EAL tree allowed identification of several duplication events. The results indicated that most of the GGDEF- and EAL- containing proteins arised by gene duplication.

根据pfam资料库(Version 17.0)，我们整理同时拥有GGDEF和EAL功能性区域的蛋白质，这些蛋白质可以被区分成两种型态，在总数621个GGDEF-EAL中有高达606个是A型态，而且它在古老的细菌Aquifex aeolicus VF5的基因体中也能找到，因此我们推测它可能是GGDEF-EAL的袓先，藉由分析创伤弧菌中所包含之GGDEF和EAL的演化关系，大部份的GGDEF-EAL会群聚在树型相近的位置，进一步比较在EAL树型上有邻近关系的蛋白质序列，根据他们的长度、与所包含的功能区域，我们找到了一些重制的演化痕迹，这样的结果指出，目前看到大多数的GGDEF 和EAL可能都是经过重制产生。

I believe that we're programmed at birth to produce endorphins when we're in close relationships.

我认为，我们的肌体在出生的时候就有这样的功能，即一旦发生任何亲密的关系就会产生内啡肽，使人与人之间保持亲密的关系纯属自然法则。

Four typical grassland communities, Stipa klemenzii, Stipa grandis, Leymus chinensis and Leymus chinensis + forbs, had been chosen along precipitation gradients from 200, 290, 350 to 450 mm respectively in Inner Mongolia Steppe. The objectives of this study were to determine the effects of grazing on plant community composition, aboveground and belowground biomass, species and functional group diversities and the relationship between diversity and productivity, the effects of grazing on soil seed bank species composition, seed density and diversity along the transect.

选取内蒙古草原三种主要草原类型(草甸草原、典型草原和荒漠草原)代表性群落羊草杂类草群落、羊草群落和大针茅群落、小针茅群落，应用样线法沿水分梯度研究放牧对内蒙古草原不同植物群落功能群组成、多样性、生产力以及多样性与生产力关系的影响和放牧对土壤种子库组成、大小以及多样性的影响，在此基础上，研究土壤种子库与地上植被间的关系。

Axonal degeneration similar to that observed in KIF 1A mutants has also been reported for several neurodegenerative diseases such as senile dementia and most recently Charcot-Marie-Tooth disease type 2A by another synaptic vesicle precursors transporter KIF1B knockout mice. In some neurodegenerative diseases, neuronal cell death caused by defects in the transport of synaptic vesicle precursors by KIF1A may be involved.

和KIF1A基因剔除鼠相似的轴突变性在一些神经退行性疾病如老年性痴呆的研究中也有发现，特别是最近，与KIF1A一样运输突触小泡前体的KIF1B基因剔除鼠与Charcot-Marie-Tooth二型疾病的关系，更提示了KIF1A基因的功能缺失，与神经退行性病变及神经元死亡的发生有不可分割的关系。
