查询词典 peat

In this paper we choose74sediment samples which are from different types of sediment (Loess-paleosol sequence sediment samples, lake sediment samples, Aeolian sand samples, peat and bog samples, Archaeological samples and surface samples). Through our investigations in the laboratory, we have some conclusion about the extraction methods of Quaternary pollen and spores from different type of sediments.

本文选取了中国北方不同沉积相的沉积物样品（黄土与古土壤样品17个、湖泊样品沉积物20个、风成砂样品11个、泥炭沼泽样品10、考古点文化层6个、表土样品10个）共74个，通过对同一种样品不同处理方法的对比研究，就中国北方不同沉积物的孢粉提取方法进行了探讨。

There are two types of coal formation: a local land accumulation in which the original substance of rotten plant material congregates in a peat bog where plants are growing; b distant land accumulation in which the original substance, which is from nearby areas or somewhere distant, of rotten plant coal congregates in a fresh water basin, lagoon, delta or lake through movements.

成煤原始物质的堆积方式分为2大类型：原地堆积——腐植煤的原始物质聚集在泥炭沼泽中植物自身繁殖的地方；异地堆积——腐植煤的原始物质是从相邻地区或大陆更远的一些地段，经过搬运，聚集在淡水盆地、泻湖、三角洲、湖泊之中。

It is suggested that quite a lot of the Be, Co, Cu and Pb could be originated from the syngenetic stage during which the coal-forming plants grew. The strongly seawater-effected peat bog with the reductive and alkaline water could be in favor of the relative enrichment of the Be, Co and Cu, and the faintly seawater-effected bog with the slightly reductive and alkaline water could be in much favor of the enrichment of the Mn, Mo, Ni, P, Pb, Th, Tl and U.

认为凯里煤中相当一部分Be、Co、Cu和Pb起源于成煤植物生长期间的同生阶段；受海水影响强烈的还原偏碱性沼泽环境有利于Be、Co和Cu的相对富集，受海水影响微弱的弱还原性和弱碱性环境条件更有利于Mn、Mo、Ni、P、Pb、Th、Tl和U的富集。

And 2 700 a B.P., respectively, based on data in 3 profiles of high moor peat deposits.

Results indicate that most of the Chinese peat belong to the low moor type, with high humic acid content around 40 to 50%.

表明泥煤多属低地泥煤，有较高的腐植酸含量(约40—50%)。

The place of Catherine's interment, to the surprise of the villagers, was neither in the chapel under the carved monument of the Lintons, nor yet by the tombs of her own relations, outside. It was dug on a green slope in a corner of the kirkyard, where the wall is so low that heath and bilberry plants have climbed over it from the moor; and peat mould almost buries it.

村里人很奇怪，凯瑟琳的安葬地点不在礼拜堂里林惇家族的已刻了字的石碑下面，也不在外面她自己家人的坟墓旁边，却是埋在墓园一角的青草坡上，在那儿，墙是这么矮，以致那些带花的长青灌木丛和覆盆子之类都从旷野那边爬过来，泥煤土丘几乎要把它埋没了。

Peat moss is well known for high porosity and perlite has a similar property.

泥炭是众所周知的高孔隙度和珍珠岩也有类似的财产。

By the time of its fall, most of the prisoners were writers who had written against the corruptions of the government.

The most obvious variation to ovum morphological character was that the color was changed from light green to sepiaceous in embryonic development, and all the ovums were almost hatched after 96h.

在胚胎发育过程中卵的形态特征最明显的变化是颜色从淡绿到深褐色，卵在发育96h后卵基本全部孵化。
