Meanwhile, the nutrient material in the deep-seated seawater that the typhoon furls makes the plankton in the sea gets enough nutrition, be helpful for marine surface layer the breed of pelagian alga, and provided indirect food source for marine fish, promoted ecological balance thereby.

和此同时，台风卷起的深层海水中的营养物质使海中的浮游生物得到充足营养，有利于海洋表层浮游藻类的繁殖，并且为海洋鱼类提供了间接的食物来源，从而促进了生态平衡。

Using BG11 as base media,the toxic effects of heavy metal Cu2+on alga Microcystis aeruginosa were studied according to the change in growth,chlorophyll-a,photosynthesis release oxygen and respire exhaust oxygen of the M.aeruginosa under different Cu2+ concentrations in the experiment conditions.

以BG11为基础培养基研究了实验室条件下重金属Cu2+在不同质量浓度下对铜绿微囊藻的急性毒性效应。试验结果表明，Cu2+对藻类的抑制效应随Cu2+质量浓度的增加而增加：质量浓度为0.3~1.2 mg/L的Cu2+对铜绿微囊藻生长的抑制作用不显著，且48 h后出现藻细胞密度反弹现象，杀藻效果不理想。

Is found to have a close relationship with the living Delesseria according to detailed morphological study between the fossil and modern Delesseria. These new findings show that the Chengjiang Biota is high in species diversity of fossil algae and might offer new evidence for a better understanding of the Cambrian explosive biological evolution and its paleoenvironment.

Nov。。通过比较形态学研究，探讨了该宏观化石藻类的分类归属与亲缘关系，进一步丰富了澄江生物群生物物种多样性的认识，并为研究早寒武世生物演化及其古环境提供了新的化石证据。

The depositional environment is the main factor for high-sulfur coal formation, and so is the participation of bacteria and algae.

聚煤环境是高硫煤形成的主要控制因素，在成煤作用过程中，细菌和藻类的参与是高硫煤形成的关键所在。

In this paper, the area in focus is Sungo Bay, one of the most large-scale aquaculture areas in North China. From the view of physical, chemical and biologic, mechanism of sediment resuspension and its ecological effect is studied; Moreover, the wave-current coupling model and prediction model of suspended sediment concentration is built.

本研究以我国北方重要养殖海湾——桑沟湾为研究对象，从物理、化学、生物三个角度出发，研究了沉积物再悬浮的发生过程以及再悬浮介质-沉积物的源汇转换角色及其与养殖藻类的关系，构建了波流耦合模型和再悬浮颗粒物浓度预测数学模型。

In organisms showing sexuality, the gametes are of two types: male and female. They may be produced in special organs (e.g. carpel and anther in angiosperms, archegonia and antheridia in lower plants and some algae). The gametes may be derived from the same parent AUTOGAMY0 or from two different parents

在显示性别差异的器官中，配子体分两种：雄配子与雌配子，二者可能在特殊器官中产生（例如：被子植物的心皮或其它结构、低等植物及某些藻类的颈卵器和精子器）配子可以来自同一亲本或由两个不同亲本分别产生。

Small order of macroscopic fresh and brackish water algae with a distinct axis: stoneworts.
