The resul ts indicated:(1) When micrococcus existed,carbon steel corrosion was accelerated by a loose and heterogeneous biofilm formed on its surfaces;(2)Rpo an d Cc values were close after two days and four days immersion respectively in solutions with micrococcus,which indicated that the metabolization of bacteria became sta ble,and the biofilms under two conditions were tend to be ripe and accordant;(3) The equivalent circuits for situations without or with bacteria were proposed respectively,and the parameters in circuits were also calculated;and (4) Corrosi on reaction impedance with micrococcus showed dispersion effect.

结果表明：（1）小球菌存在时试样表面上所形成的疏松、不均匀的生物膜加速了碳钢的腐蚀过程；（2）有菌存在时暴露2 d、4 d的Rpo值和C c值较为接近，表明细菌的生长代谢过程渐趋于稳定，两种暴露条件下所形成的生物膜趋向于成熟一致；（3）分别提出了有菌和无菌条件下EIS的等效电路，并计算了相应的等效元件参数；（4）小球菌影响下腐蚀反应的阻抗行为存在弥散效应。

Since operation variables of activated sludge process have distinct effects on the microfauna communities (here defined as protozoan and metazoan), their community structure can be used to indicate and assess the WWTP operation performance.

活性污泥工艺运行状态对微型生物的种群结构具有显著影响，可利用微型生物种群结构来指示和评价污水处理厂运行，且有利于建立面向种群优化的控制系统。

Cloudina was known as the first animal acquired mineralized skeleton at the terminal Neoproterozoic,but it was not the only exception that could secret minerals. More evidence of diverse skeletal animals came from deposits before the Cambrian"big bang". A relatively diverse tubular microfossil assemblage is described from the Terminal Neoproterozoic Dengying Formation of South Shaanxi, China.

末元古纪以Cloudina为代表的管状动物化石是目前世界上公认最早的具矿化骨骼的生物类群，在世界许多地区都有发现，但它并不是当时唯一的矿化生物类型，更多的动物骨骼化化石证据在寒武纪大爆发之前的沉积物中时有发现。

The Lower/Upper Cretaceous boundary in Songliao Basin is,therefore,between the Quantou and Denglouku formations,instead of between the Quantou and Qingshankou formations.2.The dark mudstones and shales in the Member 1 of Qingshankou Formation are of high organic carbon and low diasteranes contents.Organic geochemical characters are illustrated by biomarkers of 28,30-bisnorhopane and gammacerane,and positive excursion of kerogen isotopes.It is suggested that the dark mudstones and shales in the Member 1 of Qingshankou Formation are the products of lake anoxic period.It corresponds to the oceanic anoxic event at Cenomanian-Turonian boundary in Cretaceous.3.Based on the study of biostratigraphy,chronostratigraphy,magnetostratigraphy and event stratigraphy,a correlation of the lacustrine sequence to marine standard has been proposed,i.e.,the Quantou Formation corresponds to Cenomanian stage,Qingshankou Formation correlates to Later Cenomanian-Early Turonian,Yaojia Formation to Later Turonian-Coniacian,Nenjiang Formation to Santonian-Campanian.Sifangtai and Minshui Formations to Maastrichtian. 4.Analysis of lithology,lithofacies and microfossils of Cretaceous in Songliao Basin, shows that shore and shallow lake facies yield the most abundant microfossil groups,and the predelta and deltaic distributary plain facies rich in fossils as well.In the shore and shallow lake areas during the high level periods(such as Qingshankou and Nenjiang sedimentary periods),the lacustrine biota are of high diversity and high abundance.

因此，松辽盆地上、下白垩统的界线应在泉头组的底界，即泉头组与登娄库组之间，而不是泉头组的顶界。2、青山口组一段黑色泥岩、页岩具有有机碳含量高、重排甾烷含量低，生物标志物出现28，30—双降藿烷和伽马蜡烷，干酷根碳同位素具有正向偏移等有机地球化学特征，表征为青山口组一段黑色页岩、油页岩是古湖泊缺氧事件的产物，它对应于白垩纪古海洋Cenomanian—Turonian期界线附近缺氧事件，二者具同步性。3、通过生物地层学、年代地层学、磁性地层学和事件地层学研究，认为泉头阶大体相当于Cenomanian阶，青山口阶相当于晚Cenomanian—早Turonian阶，姚家阶对应于晚Turonian—Coniacian阶，嫩江阶对应于Santonian—Campanian阶，四方台阶和明水阶相当于Maastrichtian阶。4、通过对松辽盆地上白垩统的岩性、岩相及微体化石分析，认为滨浅湖相是微体生物群最为发育的相带，其次为三角洲前缘相和三角洲分流平原相。

Biogenic silica content was very low in continental shelf shallows and could not reflect the productivity of siliceous micropaleontology in surface waters , which may be affected by sedimentary types and terrigenous matter dilution .

陆架浅水区表层沉积物中生物硅含量非常低，不能反映表层水体中硅质生物生产力情况，这可能与沉积类型和陆源物质输入影响有关。

Marine Micropaleontology is an international journal publishing results of research in all fields of marine micropaleontology of the ocean basins and continents, including paleoceanography, evolution, ecology and paleoecology, biology and paleobiology, biochronology, paleoclimatology, taphonomy, and the systematic relationships of higher taxa.

这是《海洋微体古生物学》国际性期刊的网站，该期刊内容是有关海洋盆地和大陆的微体古生物学研究成果。包括古海洋地理，进化，生态，微体古生物学，海洋古生物学，生物学，古生物学，生物年代学，古气候学，生物埋葬学，系统发生关系。

A model of microparasite disease The reproductive rate of a microparasite can be expressed as the number of mew cases that will arise from an infected host : Rp =βSd.

微寄生物传染病模型微寄生物的繁殖率可表示为由一个感染寄主所传染的新个体数：Rp =βSd。

Biological agents or virus of rare mid-Europe diseases used in some biological terrorism can be great menace to the security of crisis intervention soldiers deployed worldwide.

某些生物恐怖活动使用生物战剂或中欧罕见的疾病病原体，这可能会对部署在世界各地的危机干预行动士兵的安全构成威胁。

The Monster of Minden'' is a badly-documented late-Jurassic specimen from the Wiehengebirge, Germany. The German edition of National Geographic for November 1999 contains an article in which this animal's ribs are described as 1.5 times as large as those of Allosaurus, and its teeth are claimed to be a foot long including the root.

从明登来的达斯怪兽""明登怪兽是一种后侏罗纪的生物，来自德国的威亨格布裏尔格的化石标本支离破碎。1999年11月份的德文版国家地理杂志刊登了一篇文章，文章中描述了这种生物的肋骨长度是与它类似的侏罗纪恐龙的肋骨的1.5倍，它的牙齿据称有一英尺长。

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

另一方面，更重要的是由于城市住房是一种异质性产品。

Climate histogram is the fall that collects place measure calm value, cent serves as cross axle for a few equal interval, the area that the frequency that the value appears according to place is accumulated and becomes will be determined inside each interval, discharge the graph that rise with post, also be called histogram.

气候直方图是将所收集的降水量测定值，分为几个相等的区间作为横轴，并将各区间内所测定值依所出现的次数累积而成的面积，用柱子排起来的图形，也叫做柱状图。
