不断变化

The change of plant functional types'importance value reflects the community members'alteration and orientation of community succession, that is: perennial grasses gradually take the place of annual or biennial forbs and perennial forbs, finally occupy dominant position in climax community.

植物功能群重要值的变化反映了群落成员型的更迭、群落演替方向，即：多年生禾草类不断取代1、2年生杂草和多年生杂草的地位，在演替顶极中最终占主导地位。

The Bay of Fundy sees some of the world's greatest tidal variability, and the constant flow continues to shape these rocks.

范迪湾看起来有着世界上最大的海潮变化，不断的水流持续让这些岩石成形。

The Bay of Fundy sees some of the world抯 greatest tidal variability, and the constant flow continues to shape these rocks.

Fundy湾具有是世界上最大的潮汐变化性，不断的水流，一直塑造着这些石头。

The radial density profile displays that positions of gas shell varies with axial position,and the gas densities on axis increases as the distance from nozzle increases.

气流的径向密度剖面显示，气体壳层的位置随轴向位置的变化而存在差异，并且随着到喷嘴距离的增加，轴心处的气流密度不断增加。

Along with enterprise paying more attention to the importance of quality detection and detection instruments using popularly,a lot of information is stored, so it is urgent to build dealing with detective data information system. This system could get timely product quality data, and grasp the quality change trend in order to support effectively maintenance of old products and decision-making for new product development, as well as help the quality detection personnel extricating of repeated , burdensome statistic and handworked work,This paper firstly bring forward storing tabacco-quality-detection data by using database technology,aiming at data storing of product detection and further analyzing demand.

随着企业对质量检测重要性认识的不断加大，检测仪器的大量使用，许多企业已经积累了大量的检测数据，迫切需要一套储存、加工处理分析检测数据的信息系统，把质量检测人员从重复繁杂的统计计算和手工作业中解脱出来，获取及时的产品质量数据，实时把握产品质量变化趋势，以求更有效地支持老产品的维护和新产品开发的战略决策。

And all this change is because the numbers of people have increased dramatically-mainly due to the explosive population growth, but also due to repeated influxes of refugees from troubled Burundi in the north, and more recently from eastern Congo.

这些变化的原因就是人口急剧增长--主要是因为人口爆炸性的增长，但是，另一个原因是从北面动荡不安的布隆迪不断有难民涌入，最近还有来自刚果东部的难民。

In control, however,the weak expression ofCY3 mRNA can be found after 48 hours of chilling and showed little increase at the third day instress.

非逆境条件下，IPT对秧苗根系中mRNA的表达差异与对照相比没有很大的变化；低温胁迫3天后，IPT对根系中mRNA的表达影响很大，既能增强某些基因的表达，又能抑制另一些基因的表达；用DDRT-PCR技术，寻找到5个低温胁迫下在对照和IPT处理中差异表达的基因，其中CY3片段与水稻CDPK1和CDPK2的mRNA有很高的同源性，初步断定CY3在植株的抗逆反应中可能具有与CDPKs相似的功能；在Genbank中没有检索到与其它4个片段同源性比较高的已知序列；IPT处理中CY3表达量在低温处理24hr就有明显升高，以后随胁迫时间的延长其表达量不断加强；恢复常温后，CY3表达继续增加，在恢复第14天开始下降，下降速度缓慢，IPT对CY3的影响一直延续到苗末期，对照中CY3在低温胁迫48hr才有微弱表达，72hr后表达量并未增加许多；恢复常温后第4天就开始下降，很快降到最低。

With continuous expansion of China's iron and steel scale in recent two years, the internal and external management environment of the Oxygen Co.

随着近两年来中国钢铁规模不断扩大，该公司的内、外经营环境都将随之发生显著变化。

The points above are just several knacks, and I hope they are helpful.

另外还有一点想要补充，那就是——语言是在不断发展变化的，所以知道最近刚出现的新词也很必要。

The results showed that, after induced for 4~5 d by dexamethasone, beta-glycerophosphate and ascorbate-2 phosphate, the volume of some cells of the goat MSCs gradually largened and changed their form from spindle/polygon to cuboid/ovoid; With the induce time continuing, the numbers of the cuboid/ovoid cells continuous increased; At 15th day, there were many cuboid cells, and the modality of the cells changed from cuboid to ovoid; At 25th day, the oval and cuboid cells accumulation were observed.

结果表明，山羊MSCs在地塞米松、β-磷酸甘油和抗坏血酸的作用下，从诱导的第4~5天开始，即可见有些MSCs体积逐渐增大，由梭形或多角形转变为立方形或卵圆形；随着诱导时间延长，立方形或卵圆形细胞不断增多，到第15天时，有较多的立方形细胞，且这种变化经历了从立方形向卵圆形转变的过程；第25天，可见卵圆形和方形细胞堆积，诱导分化率为90.2%± 2.97%。

As she looked at Warrington's manly face, and dark, melancholy eyes, she had settled in her mind that he must have been the victim of an unhappy attachment.

每逢看到沃林顿那刚毅的脸，那乌黑、忧郁的眼睛，她便会相信，他一定作过不幸的爱情的受害者。

Maybe they'll disappear into a pothole.

也许他们将在壶穴里消失
