Five pairs of primers were designed for PCR according to five fragments of the putative virulent genes acquired by suppression subtractive hybridization between virulent strain HA9801 and avirulent strain 12 of Streptococcus suis type 2 （ SS2 ）. The five fragments were transcriptional regulator (15# and 154# fragments), amino acid permease (210# fragments), ABC transporter (9# fragments) and surface anchored protein (187# fragments).

The earliest and reliable Castanopsis fossil records date back at least to Eocene, and subfamily Castaneoideae fossil records found from Paleocene, it is indicated that appearance of Castanopsis is not later than Paleocene . All fossil records of Fagaceae and Castanopsis report from the Northern Hemisphere and their main distribution regions are in the Northern Hemisphere . It can be concluded that the Northern Hemisphere is the center of origin of Fagaceae and Castanopsis . However, owing to the discrepancy between fossil data and results of modern botany research as well as scarcity of fossil data from key area, precise center of origin of Castanopsis cannot be inferred.

在这假定46亿年的长河中，究竟发生了什么，早已无法述说；只有从古老的地层中，发现的生命过程残存的遗迹，还可以见证一丁点儿的遥远过去，诸如：三叶虫化石、鱼化石、蕨类等早期动植物化石，以及之后的恐龙化石、鸟化石、原始时代动物及人类祖先的化石，还有古代人类历史文明中的尸体躯壳与非躯壳遗迹等等，这些遗迹几乎跨越了整个地球的生命演变史。

The fossil collections are important both scientifically and historically, with exceptionally well-preserved specimens from the Midlands and many other famous fossil localities in the UK, and throughout the world.The museum has some of the finest collections from the Wenlock Limestone of Dudley, famous for its fossils that lived 420 million years ago when the area was covered by a shallow, warm, tropical sea that enabled a highly diverse ecosystem to develop. From the rocks of the old Midlands Coalfields are important collections of fossil plants, fish, insects, arachnids, fossil footprints and animal tracks.

周口店北京人遗址位于北京市西南房山区周口店镇龙骨山北部，是世界上材料最丰富、最系统、最有价值的旧石器时代早期的人类遗址。1921年至1927年，考古学家先后三次在"北京人"洞穴遗址外发现三枚人类牙齿化石，1929年，又发现了北京人头盖骨化石，以及人工制作的工具和用火遗迹，遂成为震惊世界的重大考古发现。1930年在周口店遗址还发现距今约2万年前的山顶洞人化石和文化遗物。

The study has shown:(1) With increasing sediment depth and the woody giblets, the total organic carbon, the extraction of benzene , the total humic acids and the unhydrolyte are enhanced, while the hydrolyte is decreasing.(2) According to the GC-MS analysis, n-alkane,n-alkan-2-ones and n-alkanones are composed mainly of long-chains,such a result is thought to be characteristic of a herbaceous input from 2300a.B.P. n-alkanones exist in the samples may be considered as the evidence of microorganisms activity.(3) It is showed that the lipids is more sensitive to the climate change than the floristic. The proxy of the pollen spore of the peat stratum is different from the normal environment proxy. It is one of the main reasons that the sensitivity difference of the bog vegetation reacting to the climate isn't accordant with the log of the fat molecule fossil and biology fossil.(4) The transformation of the peat organic carbon is under the influence of temperature,acidity,organic material constituting, etc, and it showed the up-trend with the depth. In the short-term scale, the conversion of the peat organic carbon is effected by seasonal water,regional climate and vegetations; while in the long-term scale, it is controlled mainly by the climate.(5) According to the comparing the orderliness of organic compound,vegetation giblets with the depth to the characteristics of the peat molecule fossil with the section, in the development of this peatmire, 1500a B.P（210cm）is regard as the borderline of the late Holocene, the keynote of the front period is warm with several cold fluctuations, and the trend of the back period is dry and cold although there were several fluctuations.

研究表明：（1）随深度的增高及植物残体中木本残体的增多，总有机碳、苯萃取物、总腐植酸、不被水解物含量逐渐增高，而易水解物含量减少；（2）GC- MS分析显示，正构烷烃，直链烷基2-酮和正烷醇均以长链组分为主，揭示了该泥炭柱剖面2347a.B.P的母源输入以草本植物为主；甲基酮类和短链正烷醇的存在是微生物活性很大的生物证据；（3）通过有机分子标志物与孢粉、植物残体等指标的对比研究表明：脂类化合物对气候变化的反映要比植物种灵敏得多，不同沼泽植物对气候变化的敏感性的差异是脂类分子化石记录与生物大化石结果很难一致的主要原因之一；（4）泥炭有机碳的转化受到温度、酸度、有机物质组成等很多因素的影响，短时间尺度，泥炭有机碳的转化受季节性降水、地方气候和植被等因素的影响；长时间尺度，泥炭地有机碳的转化，受气候条件控制；（5）总结泥炭分子化石特征、泥炭有机质各组分含量及植物残体组成随深度的变异规律，分析结果显示该泥炭地层形成过程中，1500a B.P（210cm）可作为划分前后晚全新世的界线，前期的基调是气候偏暖，但又有几次偏干冷气候的反复，后期气候以干冷为主，其间虽有几次上升波动，但整体趋势不变。
