渐变

You go from an ecocline to ecotone.

你会一下从生态渐变群[3]转到生态交错群[4]

Considering that generation and maintain of small radius, high power beam is restricted by the compression ratio of electron gun, the effect of magnetic field on electron trajectories in transition region was analyzed.

分析了过渡区中电子注调节的基本原理，设计了一种渐变式的过渡区结构，其注腰半径为0.8mm，周期均匀磁场峰值为0.29T，周期为4.5mm，压缩比为22。

Results The axial length of eyeball was gradually decreased during the adult years of life accompanying with the increases of corneal and lens refractive powers and a decrease of anterior chamber depth fur maintaining a emmetropia status, and the steepness and thickness of lens, shallowness of anterior chamber contributed to emmetropia by decreasing the refractive index of lens.

结果 随着年龄增大，眼轴逐渐变短，但同时伴有角膜、晶状体屈光力的增大及前房深度的变浅以维持正视状态，晶状体的增厚、曲率的变大及前房的变浅可能通过屈光指数的减小同样维持了正视状态。

But in SD rats, cardiac muscle fibers were fractured seriouly , contracted to wavilness obviously, then muscle fibers fracture were contracted like entasia by the hypoxia time increased , injury intensify , all the changes refered SD rats compensatory mechanism can not be transferred in this hypoxia degree. 3. Exposed to 4% oxygen concentration, the cardiac muscle ultrastructure of Gansu zokors had serious injury after hypoxia 2h.

在4%氧浓度的低氧耐受实验中，甘肃鼢鼠在低氧2，4h后，心肌纤维收缩明显呈波浪状，低氧时间延长至6，8和10h后，心肌显微波浪状收缩由强逐渐变弱，并逐渐恢复至正常状态，说明鼢鼠心肌在6h以后对严重缺氧环境开始代偿性适应；SD大鼠2h组心肌纤维断裂严重，收缩加强成明显的波浪状，随着低氧时间得增加，4h组呈严重成挛状收缩，损伤加剧，提示SD大鼠在这一氧浓度下已经无法正常调动其代偿机制。3。

The epidemiology investigation showed that the morbidity and mortality of it is remaining increasing in recent years.

癌的渐变过程，使肺癌的早期诊断和早期治疗成为可能。

Just as a general egg cell differentiates through epigenesis to become a legion of specialized cells, so in evolution animals and plants split up into varieties more dependent on narrower niches.

正像一个普通的卵细胞经过后来的渐变分化成众多不同的专门细胞，在进化中，动植物也分化成更多不同的种类，各自适应一个更窄的生态龛。

The main works are as follows: 1 The developingt history of the traffic load on bridges is represented. Typical bridge codes in some countries are discussed and these traffic load models are comparative analyzed. Analysis shows that the influence of layout axle for the total traffic load effect on bridge gradually becomes smaller with the increase of bridge span. So most national norms use the distributed load as the equipollent load of traffic load.

主要内容包括下面几个方面： 1阐述了桥梁汽车荷载发展的简史，讨论了部分国家典型的桥梁汽车荷载设计规范，并对这些荷载模型进行了对比分析，分析表明随着桥跨的增大，车轴布置对桥梁整体荷载效应的影响逐渐变小，因而大部分国家的规范都把均布荷载作为车辆的等代荷载。

The simulating results showed that the multi-triangle structure is more effective, compared with simple erective noise barrier.

根据模拟结果设计了渐变腔T形顶部结构加多重楔形组合的声屏障并在京秦高速公路进行了工程实践。

Jing is a fundamental structure of Qihua which can't express any defference of future life at stage of Jing; Yin Yang expresses the evolution regularity of life which has defferent nature; five elements expresses a team of natural number which under five elements and it contral life to evolute at five stages.

生殖之精，是生命基本的化演单位，气化之宇。阴阳，表达生殖之精依靠气化，演化出的具有某些相对的可比较属性。五行，是反映生命体在气化作用下，同源演化区域里生命结构或功能渐变的五大变化序态。

Evolution rather than revolution is the chosen course because, as the Fabian Society noted, the wolf in sheep's clothing stands a better chance of getting lunch than his colleague openly salivating amongst the flock.

渐变而非革命是选定的课程，因为正如费边社所指出的那样，狼对羊的衣服有一个更好的机会越来越午餐比他的同事公开垂涎三尺当中羊群。

However, as the name（read－only memory）implies, CD disks cannot be written onorchanged in any way.

然而，正如其名字所指出的那样，CD盘不能写，也不能用任何方式改变其内容。

Galvanizes steel pallet is mainly export which suits standard packing of European Union, the North America. galvanizes steel pallet is suitable to heavy rack. Pallet surface can design plate type, corrugated and the gap form, satisfies the different requirements.

镀锌钢托盘多用于出口，替代木托盘，免薰蒸，符合欧盟、北美各国对出口货物包装材料的法令要求；喷涂钢托盘适用于重载上货架之用，托盘表面根据需要制作成平板状、波纹状及间隔形式，满足不同的使用要求。
