藻类的

In this thesis, the mathematics model was used to simulatc the alage growth in Lake Taihu; An enzyme-linked immunosorbent assay was used to monitor the spatial and temporal distribution in 2001; The microcystis spp was culturede with scendesmus obliqaus to study the toxin secrete mechanism of the MC from the population competition; The degradation of the MC by the sediment collected from Lake Taihu and one of the submerged mcrophyte Elodea nuttalli were discussed.

本文采用数学模型的方法模拟了太湖藻类的生长情况；应用酶联免疫吸附法监测了2001年MC的时空分布情况；在实验室内进行藻类培养，从种群竞争的角度初步探讨了MC的产毒机理以及太湖底泥和沉水植物对MC的自然降解作用等。

The concentration of carbon dioxide in natural seawater is sufficient for microalgal growth, but insufficient for high algal-density culture due to limitation of photosynthesis in the artificial medium. This study was adjusted the initial pH to 5.5, 6.5 and 7.5 by adding CO2 or HCl in 1L flask cultured stagnantly with continuous illumination.

对大多数藻类而言，在天然的水域中，二氧化碳的浓度是充足的，但在人工培养的情况下，藻类的密度很高，二氧化碳的供应往往不足，成为光合作用的限制因子，进而影响藻细胞的生长繁殖。

Precipitation. More precipitation more species quatities of subaerial algae are.

降水量。降水量少的地区，其亚气生藻类的数量多于降水量多的地区的亚气生藻类种类数量。

The distributions of subaerial algae in Jilin's terrestrial ecosystem are different with the difference of zonal vegetations. The distinction is embodied in the species quatity and subaerial algae's thallus shape.

由于各种因素的综合影响，东北森林-草原样带中的各地带性植被内的亚气生藻类在分布上有较大差别，这种差别主要体现在种类数量和藻类的原植体形态上。

Majuscula. Our researches were significant for the chemical taxanomy of Laurencia, and the exploition of the natural products from this seaweed in our country.

本文关于凹顶藻次生代谢产物的研究结果，进一步丰富了凹顶藻化学研究成果，特别是丰富了我国对于该属藻类的研究资料，同时提供了该属藻类的化学分类以及天然产物资源开发利用的参考。

In order to reveal the effects of tilapia on phytoplankton and periphyton, an experiment with two treatments, one with tilapia and one without tilapia (non-fish group) was carried out, and the biomass of both phytoplankton and periphyton was analyzed.

为了解罗非鱼对浮游植物和附着藻类的影响，实验在室外模拟条件下，分别设置罗非鱼组和无鱼对照组的两组处理，分析了罗非鱼对附着藻类及浮游植物生物量等的影响。

This essay chooses the study aim from biology teachers in middle school in Shi Jiazhuang which tells us that most of the middle school biology teachers in Shi Jiazhuang have the"burnout", lower successfulness, individualize.

本文选取石家庄市初中生物教师作为研究对象，运用问卷调查的方法对石家庄市初中生物教师职业倦怠的现状进行调查，调查结果发现，石家庄市初中生物教师这一群体普遍存在职业倦怠，情感枯竭程度偏高，成就感偏低，去个性化程度最为严重。
