隔离

Mayr emphasized the importance of allopatric speciation, where geographically isolated sub-populations diverge so far that reproductive isolation occurs.

迈尔强调异域成种的重要性；在地理上孤立的亚群产生的分歧偏离太远，以致出现生殖隔离。

There are four geographic modes of speciation in nature, based on the extent to which speciating populations are geographically isolated from one another: allopatric, peripatric, parapatric, and sympatric.

自然界有四种物种形成的地理学模式，基于形成物种的各群体之间地理隔离的程度分为：异域的、边域性的、领域性的和同域的物种形成。

Allopatric speciation occurs when the new species evolves in geographic isolation from the parent species.

异域性物种形成与原来种由于地理隔离而进化形成新种，为异域性物种形成。

During allopatric speciation, a population splits into two geographically isolated allopatric populations (for example, by habitat fragmentation due to geographical change such as mountain building or social change such as emigration).

在异域的物种形成中，群体分成两个地理上隔离的异域群体（如因山脉形成等地理变化导致的生境破碎化、移民等造成的社会变化）。

Allopatric speciation occurs when the new species evolves in geographic isolation from the parent species.

形成与原来种由于地理隔离而进化形成新种，为异域性物种形成。

The invention provides an antennal separator which can be configured by less size and lower height than previously without damaging property of attenuation outside a channel and separating property between an emission terminal and a receiving terminal.

本发明提供了一种天线分离器，其能够以比以前更小的尺寸和更低的高度来构造而不会损害带外衰减特性及发射端子与接收端子之间的隔离特性。

UDZ Series liquid level indicator of flap disassembly fast and convenient, the installation position can be arbitrary choice, free to change the direction of observation, thus instrumented great visibility; UDZ series of cost-effective liquid level was significantly higher than that used multiple sets of glass plate liquid level of cost performance; UDZ series of liquid level indicator, the sender's device, as well as the liquid level with the main transmission medium within the complete separation of the measured structural design, so that level gauge in the job has pressure (up to 320KG), toxic and inflammable conditions, with absolute safety and reliability; UDZ-3 type uses innovative design, improve the sensitivity of the sensor, and its near-zero drift FarEasTone signals and long-term stability so that it has always been at the scene consistent level instructions; sensors and the main body has a certain interval, which can be solved effectively under high-temperature liquids (up to 480 ) remote detection and control; antifrost type UDZ Series Level Gauge, are I plant the patented product (Patent No.: ZL00221022 3), guarantees that the use of cryogenic liquid level gauge is not freezing (such as liquid CO2), the effective guarantee of the level of a normal job.

UDZ系列液位计的翻板指示器拆装快捷方便，安装方位可任意选择，观察方向可随意改动，因而仪表指示的可视度很大；UDZ系列液位计的性能价格比明显高于采用多组玻璃板式液位计的性能价格比；UDZ系列液位计的指示器，发讯器、以及液位变送均与主体内被测介质完全隔离的结构设计，使液位计工作在有压（可达320KG）、有毒和易燃的工况下，具有绝对的安全性和可靠性；UDZ-3型采用了新颖设计，提高了传感器的灵敏度，其远传信号近乎零温漂和长期稳定性使其始终于现场液位指示保持一致；传感器和主体有一定的间隔，因而能有效地解决高温液体（可达480℃）远距离检测和控制；防霜型UDZ系列液位计，是我厂的专利产品（专利号：ZL00221022·3），保证了在低温液体上使用液位计不结冰（如液体CO2），有效的保证了液位计的正常工作。

Mr Mandela spent 27 years in prison for opposing the apar the id administration.

曼德拉因为反对种族隔离制度而在监狱里度过了27年。

We will separate the manufacturing place to ensure the hygiene and cleanning of product, to catch the cure requirement. It will be had good aerator and serious hygiene system. We will surveil all proccess on product from raw matterial to finish goods; Equipments are almost special, e.g. measure, mixing and so on. There is relevant functionaries for every equipment, they will inspect equipment aperiodically to avoid any pollution. We did body checking for every operator, they can only work with good healthy and stated work clothes. 2. Working equipment: A:Plastic injection machine.

为保证产品的卫生清洁，满足医用要求，我们将对生产现场进行隔离，形成了一个相对封闭的环境，并配备有良好的透风设施，制定了严密的卫生制度，从原料进厂到成品入库的全过程，都有专人对卫生状况进行监控，确保了现场环境的整洁；在设备管理方面，大部分设备都是专用的，如计量设备、掺混设备等，而且每个设备有相应的负责人对设备进行不定期巡查，以防因设备不干净而对产品造成污染；对每一个操作人员，在上岗前都进行了体检，只有达到健康要求的才准许上岗，并且在工作期间，必须穿戴好定做的工作服。

Because divergence timing of the West Clade from the East Clade of S. japonica complex was estimated to be Aquitanian of Miocene (23 Ma), during which the mountains and plateau of Southwest China were formatted, the divergence of the West Clade from the East Clade of s. japonica complex was presumably correlated closely with the uplifting of mountains and plateau of Southwest China. The multiple variations of the West Clade of S.

西部集群居群间具有更大的遗传分化值和更大的遗传分化值变动范围，提示西部物理环境的复杂性导致更多的小区域隔离，小的基因流和更大的绝对成种速率，这与西部的物理环境的复杂性是相协调的，并且可能是造成西部山地高原地区生物多样性异常丰富的微观过程和机制。
