查询词典 adaptation

Adaptation to seawater in Lactuca indica was mainly caused by strong K+ selective absorption and transport. Furthermore, accumulating soluble sugar and protein were important osmotica in Lactuca indica seedlings and it could be characterized as an indicator of salt tolerance.

海水胁迫下，苦荬菜幼苗维持一定的K+离子选择性吸收是其一定程度上盐适应的重要原因；同时，可溶性糖、可溶性蛋白的积累作用是苦荬菜幼苗盐胁迫下的重要渗透调节物质，可以作为其抗盐性的生理参数。

The differences in 3D morphology of osteocytes and their lacunae in long bones of different pathologies with different BMD might reflect an adaptation to matrix strain due to different external loading conditions.

不同BMD条件下不同病理的长骨骨细胞和其陷窝3D形态上的不同反映了其对不同外负荷条件下所受矩阵应力的适应情况。

These fossils represent different major groups and show high diversity in body size, locomotory adaptation, and dietary.

这些化石代表了不同的哺乳动物大类，同时显示了在个体大小、运动姿态以及食性方面的较高的分异。

Perhaps it is due to its role in adaptation that A. longa and other bleached species of euglenoids retained their proplastid structure.

或许正由于原质体结构在竞争适应中的效应，长变胞藻和自然界某些裸藻褪色种仍保留有这一结构。

The aim of this study was to longitudinally investigate their status of adaptation in terms of changes in their quality of life.

本研究共徵召63位11-18岁肢体障碍组的儿童和青少年以及282位来自相同地区一般正常组学生，他们都是来自於高雄市教育局所管辖国小五年级以上到高中学校的学生。

In addition, we had obtained evidence of harboring the lysogenic phages in Stroptococcus suis type 2, but the relationship of this phage with the bacterial virulence and adaptation was uncertain.

尤其是猪链球菌2型，不仅对猪致死性强，而且可引起人的感染和死亡1998—1999年夏季曾在我国江苏省部分地区猪群中暴发流行2型猪链球菌病并导致相关从业人员感染。。。。。。

Studies of the mechanism of meiotic recombination indicate that meiosis is an adaptation for repairing DNA.

减数分裂重组机制的研究表明，减数分裂是一个为了修复DNA的适应。

In this thesis, we chose two wild rodents inhibiting in the north of China Mongolian gerbil (Meriones unguiculatus and Brandt's vole . The effects of short photoperiod and cold exposure to thermogenesis, and the mechanism of thermogenic regulation were studied. The new genes participating in cold adaptation were also screened by DDRT-PCR.

本文选择了华北地区的两种野生啮齿类（生活在内蒙古荒漠和半荒漠地区的优势鼠种长爪沙鼠和生活在内蒙古干旱草原的优势鼠种布氏田鼠）为研究对象，探讨光照对长爪沙鼠产热的影响，以及在低温因子作用下两种鼠适应性产热变化的机理，并利用差异显示技术试图寻找与冷适应性产热相关的基因。

Methods: The rapid oscillatory and slow components (a- and b-waves) of single ERGs were simultaneously recorded in nine healthy, young subjects in response to first flash after both DA of 45 mins and light adaptation to a steady background light of low mesopic intensity.

选取9位健康青年受试者，记录其在45分钟的暗适应后及在中间照明亮度背景下的明适应两种不同情形后闪光刺激的ERG，描记a波和b波情况。

We conclude that early, scotopically related OPs may indeed be activated in the single response to the first flash in DA (i.e. without using conditioning flashes). Secondly, on its own, adaptation to mesopic BGL does not seem to trigger enhancement of the overall oscillatory response. The altered single oscillatory response to the first flash apparent in the mesopic BGL comprises a third cone-associated OP and seems to reflect a reorganization of the retinal microcircuitry from a predominantly rod-activated system to one of mixed rod cone neuronal activity in the inner part of the retina at the level at which individual OPs have their respective origins.

暗适应相关振荡电位可由暗适应后的闪光刺激激发形成，中间亮度照明背景的适应没有增加总振荡电位波幅，新增加的和视锥细胞活动相关的第三波峰可能反映了视觉系统适应活动的重新整合，即从之前的以视杆细胞活动为主导，转为视杆/视锥细胞的共同作用。

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。
