The Carboniferous is a key period of the Phanerozoic reef evolution. There are mainly six common types of the Carboniferous organic reefs:(1) phylloid algal mounds,(2) stromatolic mounds,(3) coral reefs,(4) Waulsortian mud-mounds,(5) Chaetetes mounds,(6) microbial-algal mounds.

石炭纪是生物礁地史演化过程中一个非常关键的时期，发育的生物礁类型有：叶状藻礁丘；(2)叠层石礁丘；(3)珊瑚礁；(4)Waulsortian灰泥丘；(5)Chaetetes礁丘；(6)钙质微生物－藻礁丘。

It was shown that the algal species composition and cell densities in the reservoir varied markedly among the three periods. At present, the algal community in mainstream was dominated by Bacillariophyta, and then Chlorophyceae.

数据显示，蓄水前（2003年1月~2003年6月）、蓄水1周年（2003年6月~2004年5月）和蓄水1.5年（2004年6月~2004年12月）3个时间段之间，被调查水域的浮游藻类群落结构、细胞密度和水质状况均存在一定的差异。

Closed-system algal toxicity test was applied to evaluate the toxicity of secondary and tertiary propargylic alcohols to Pseudokirchneriella subcapitata. The effects of propargylic alcohols were evaluated by three kinds of response endpoints, i.e., dissolved oxygen production, cell density, algal growth rate.

bstract：本研究以藻类（Pseudokirchneriella subcapitata）利用BOD瓶进行一密闭式系统之毒性试验，使用溶氧变化量，藻细胞的数量变化，以及以藻类细胞密度变化量计算所得的生长率三个终点，评估二级以及三级炔丙基醇类之毒性，藉由Probit模式求出半致死浓度（50% Effect concentration，EC50）。

It was found that the bioaccumulation of Ct on Spirulina platensis involved two steps:rapid adsorption and slow absorption. Chromic compounds with weaker chemical bond had higher bioaccumulation efficiency. Under the same algal cell concentration, Crbioaceumulation rosed up with Crconcentration. On the other hand, with Cr concentration not changed, the total bioaccumulation of Cr on Spirulina platensis increased with algal cell concentration, but the Cr bioaceumu lation on unit algae reduced.

发现螺旋藻对Cr的生物富集主要经历了快速的吸附和缓慢的吸收两个步骤；化学键较弱的Cr化合物具有较高的富集效率；藻细胞浓度一定时，随着Cr浓度的增加，单位重量螺旋藻对Cr的富集量不断增加，最后趋于饱和；当Cr浓度一定时，随着藻细胞浓度的增加，螺旋藻对Cr的总富集量逐渐增加而单位重量藻体的富集量减少。

Toxic effects of HgCl2 on Scenedesmus obliquus were studied in this paper. Algal growth, photosynthetic pigments content, super oxide dismutase activity, malondialdehyde content in the algal cells were measured in the exponential phase.

为探讨汞对藻类的毒性效应，以斜生栅藻为实验材料，检测了HgCl2对藻细胞数目、光合色素含量、超氧化物歧化酶活性、丙二醛含量等生化指标的影响。

Reproduction in lichens may be asexual by soredia (algal cells enclosed by fungal hyphae) or by sexual fungal spores, which can survive only if some algal cells are also present.

地衣可以利用粉芽进行无性生殖或利用真菌孢子进行有性生殖。

The major organic source for algal-farming Stegastes damselfishes was likely to be the polychaetes hidden in the algal lawn. The algae farmed by the fish were possibly to secure polychaetes rather than to use as food source. Moreover, the widespread territory overlap between Pacific gregory and blennies was possibly a sign of mutualism.

另外，草食性的领域性真雀鲷可能是以栖身在领域内藻床上的多毛类动物为食，其藻耕行为则是为了培养多毛类食物，而太平洋真雀鲷与鳚科鱼类之间领域的重叠则可能是一种互利的现象。

Uni-algal cultures were made first on media enriched with nitrogenous compounds to encourage vigorous growth.The uni-algal cultures were then subcul- tured onto nitrogen-free media,which effected a preliminary separation of those algae which could thrive in the absence of pre-f...

在100毫升无菌无氮培养基中生长四天的结果测定，水生686固氮蓝藻、水生678固氮蓝藻(A.azotica forma a)、水生670固氮蓝藻和水生508固氮蓝藻的固氮量分别为1.0146、0.938、0.8614和0.759毫克。

The study area covers 4 mines producing sclerotia algal type coal in Hunyuan,Shanxi Province.the study combined both coal petrologic and geochemical methods indicated that the sclerotia algal coal is physically and chemically different from humic coal apparently,the forming environment is mainly controlled by pH,Eh and organic content,in which Pila Alginite and Reinschia Alginite are highly dominated.

运用煤岩学和地球化学方法，对中国山西浑源等 4个典型的菌藻类煤进行了综合研究，结果表明，菌藻类煤在物理、化学组成和特性上与腐植煤有明显的区别；其形成环境主要受 p H、Eh值和有机质含量的制约，其中皮拉藻和轮奇藻具有含量高、生存时间长的特征；并在此基础上对菌藻类煤作了成因分类

Finally, the Knight strung a line between two of the monoliths and tied the horses up there.

最后，骑士们在两颗巨石之间拉了一条绳子，将他们的座骑绑在上面。
