干旱

The characteristics of major, trace and rare earth elements suggest a protolith association of iron-rich dolomitic pelite, calcareous mudstone and greywacke intercalated by pelitic limestone and marlite, calcareous-bearing arkose, which was deposited in the setting of dry, intertidal or laguna with insufficient supply of the terrigenous detrital material.

常量元素、微量元素和稀土元素的分布特征说明是一套由富铁白云质泥岩－钙质泥岩、钙质杂砂岩夹泥质灰岩、泥灰岩－含钙质长石砂岩组成的沉积建造，形成于干旱气候、潮间带或泻湖、陆源碎屑供给不足的环境中。

Small plant having pleasantly acid-tasting arrow-shaped leaves; common in dry places.

矮小植物，叶子箭形，有宜人的酸味；干旱地区常见。

In both instances, a heatwave following years of drought provided tinder for an arsonist's match.

这两次火灾都是长年干旱导致的热浪引燃了纵火犯的火柴造成的。

Perhaps it is humankind's long suffering at the mercy of flood and drought that makes the ideal of forcing the waters to do our bidding so fascinating.

可能是因为人类太长时间遭受洪水与干旱的折磨，使得控制洪水的理想变得如此有吸引力。

Thischaracteristic of Atriplex canescens is consistent with that of many local species. TheLCP of Atriplex canescens in different treatments (light, medium, no and heavy watersoil stress) are 314.8μmolm~(-2)s~(-1)、272.5μmolm~(-2)s~(-1)、176.7μmolm~(-2)s~(-1)、143.1μmolm~(-2)s~(-1), respectively, which indicates that the LCP of Atriplex canescens is reducingwith the escalation of soil water stress. This tendency is favorable for Atriplexcanescens under drought stress to maintain certain photosynthesis even in weaksunlight so as to ensure the survival of itself, and keep balance between maintainingwater content inside and its photosynthesis.

四翅滨藜在不同土壤水分胁迫下的光补偿点：轻度土壤水分胁迫、中度土壤水分胁迫、无土壤水分胁迫和重度土壤水分胁迫下的光补偿点分别为，314.8μmolm~(-2)s~(-1)、272.5μmolm~(-2)s~(-1)、176.7μmolm~(-2)s~(-1)、143.1μmolm~(-2)s~(-1)，说明四翅滨藜的LCP随着土壤水分胁迫的加重而呈现降低的趋势，这种变化有利于处在干旱胁迫中的四翅滨藜在光强较弱的条件下仍然能维持一定的光合作用，以满足植物自身生命活动所需，同时也可以使植物在保持体内水分和进行光合作用之间寻找平衡。

Atriplex canescens is an evergreen shrub introduced from the United States. Trials onits ecophysiological and drought-resistance features were conducted.

从美国引进的准常绿灌木(2年生实生苗)—四翅滨藜在民勤干旱沙区进行抗旱生理生态试验。

The trials on cultivation of Atriplex canescensconducted in Minqin Desert Control Experiment Station reveals that this speciesentails fine qualities as strong tolerance in drought, cold, salinity and low temperatureas well as high annual biomass. So it cab be extended in sandy areas with favorableirrigation condition, and on hilly in loess plateau with relatively high rainfall and lowevaporation. As a new substitute species for water/soil conservation and rangelandregeneration, it has a big potential to be extended. However, more research on withinwhich scope this species can be extended need to be done

从干旱沙区民勤治沙综合试验站的栽培来看，四翅滨藜在此地表现出了耐旱、耐寒、耐盐碱、耐低温且年生长量大的优良特性，因此可以在有灌溉条件的沙区和降雨较多且蒸发较小的黄土丘陵区进行推广，作为该地区的水土保持和草场更新的新物种，具有一定的推广潜力，但推广地域范围的划分，仍需进一步的试验研究和充分的科学论证。

Under no andheavy soil water stress, there"s a great change of Atriplex canescens"s physiologicalindexes, Tr and Cs increased while Pn, WUE and LS decreased, its growth andbiomass reduced substantially, which reveals it can hardly survive under extremelydry habitat.

在无土壤水分胁迫和重度土壤水分胁迫下各项生理指标变化显著，Tr、Cs增加和Pn、WUE、LS下降，生长量和生物量的大幅度下降，表明其在特别干旱的环境条件下难易生存。

The OsCMO contains 10 exons and 9 introns and encodes a protein with 410 amino acids,which shows 62﹪, 51﹪, 51﹪, 51﹪ and 50﹪ identities in amino acids to CMOs from Arabidopsis thaliana,Atriplex hortensis, Amaranthus tricolor, Suaeda liaotungensis and Beta vulgaris respectively. Semi-quantitative RT-PCR assay revealed OsCMO was significantly up-regulated in the rice seedlings under salt, cold and drought stresses. It suggests that OsCMO might play an important role in rice responses to abiotic stresses.

该基因含有10个外显子和9个内含子，其开放阅读框编码一条长为410个氨基酸残基的多肽，与拟南芥、山菠菜、苋、碱蓬和甜菜等植物的胆碱单加氧酶的氨基酸序列的一致性50﹪～62﹪。mRNA分析表明OsCMO基因在水稻幼苗组织中的表达受高盐、低温和干旱等胁迫的上调诱导表达，表明该基因可能在抵御非生物胁迫中发挥重要作用。

Between these extremes lie the sal -dominated moist deciduous forest of eastern India; the teak -dominated dry deciduous forest of central and southern India; and the babul -dominated thorn forest of the central Deccan and western Gangetic plain.

在印度的上述热带雨林带和针叶树林带之间，印度东部以潮湿性落叶林带的婆罗双树为主，印度南部和中部则以干旱落叶林带的柚木树林为主，印度中部的德干高原和恒河平原则以热带旱生林带的阿拉伯相思树为主。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
