Can undertake nutrition of light energy inorganic is divided inside the cell of general alga contain and the light with advanced same plant adds up to green outside pigment, some kinds group still have in all special pigment and also do not show green more, so their plastid calls chromatophore especially or hold lubricious put oneself in another's position.

能进行光能无机营养一般藻类的细胞内除含有和绿色高等植物相同的光合色素外，有些类群还具有共非凡的色素而且也多不呈绿色，所以它们的质体特称为色素体或载色体。藻类的营养方式也是多种多样的。例如有些低等的单细胞藻类，在一定的条件下也能进行有机光能营养。

It"s considered that the algae blooms control function in the algae"s growth dynamics model is influenced mostly by the water temperature, sun illumination, water flow speed and the concentration of the nutriment in water. A function including the four elements was built. By using cell mapping algorithm and contacting with the practical water condition of the Wujiang river and the Hanjiang river we analyzed and computed the algae blooms in the two areas and found the result was very near to the practical result. And we found that the ascend of water temperature and the descend of the water flow speed will contribute to the growth of algae and the nutriment is the substance basis of the algae blooms but not the only element. It must be under the condition of condign water temperature, enough sun illumination, slow water flow and abundant nutriment that algae blooms may break out unexpectedly.

本文认为藻类生长营养动力学模型中的水华爆发控制函数主要受水温、光照强度、水流速和营养盐浓度的影响，构建了包含水温、光照强度、水流速和营养盐浓度的水华爆发控制函数，通过对乌江、汉江的水华爆发进行胞映射分析，得到的计算结果与实际监测非常吻合，并认为水温升高和水流速下降将有利于藻类生长，营养盐是水华爆发的物质基础，但不是唯一因素，必须在适宜的水温、光照、缓慢的水流和充足的营养盐条件下，藻类才可能出现突发式的"疯长"，即水华爆发。

Volvocales An order of the Chlorophyta containing motile unicellular algae (e.g. Chlamydomonas), colonial forms (e.g. Gonium), and coenobial forms (e.g. Volvox).

Base on content of chlorophyll a and feeding type of fish and shellfish a food web methods was designed to control eutrophilication. The native freshwater bivalve,Anodonta woodiana, was selected as a filter to remove the algae in the water. The result is quite satisfied and promising.

本研究以水中叶绿素a浓度为基础，鱼类食性为辅，发现使用本土种且具有经济价值之淡水圆蚌，来作为滤除水中藻类的生态方法颇具可行性，利用藻类吸收营养盐、圆蚌食用藻类、再将圆蚌移除之方式而达到降低水库营养盐能量的目的。

The biomarkers such as the n-Alkanes, the isoprenoids, the terpane, and cholestane were detected through GC-MS analysis. Based on the study of the biomarkers, the biological evolution during Permian and Triassic can be divided as three stages, namely, the mixing source stage of low biota such as thallose and advanced plant in late Permian (below bed 63), the stage of low biota such as thallose in the boundary transitional layer (bed 63-69) and the mixing source stage of advanced plant and low biota such as thallose in early Triassic (above bed 69). What's more, the second stage near the boundary transitional layer can be subdivided into 4 stages. The stages of biota evolution is close related with sedimentary environment changing and the boundary transitional layer.

Were used; for filter-eeding experiment, the alga used was Nitzschia closterium, and the experimental temperatures were 20, 23, 26, 29℃.Results show that the feeding selectivity of small-ized bay scallop and the oyster increase with algae size:when the algae increased from 4.35m to 11.6m, the feeding rate of bay scallop increased from 4.21%to 11.0%and that of the Pacific oyster from 0.81%to 3.15%.
