Currently, the impact of excessive phosphorus on water bodies focuses on eutrophication and algae overrun, which have been the hotspots and intractable problems for environment protection in China, essentially an outcome of the concentration of the compounds of nitrogen and phosphorus, and the heavy reproduction of aerobe.

当前过量磷对水体产生的影响集中地表现为富营养化和藻类繁生现象，其实质是耗氧有机物及氮、磷化合物的生态环境效应。它们已成为我国环境保护的热点甚至是十分棘手的控制治理问题。

In all plants and some algae there is an alternation between sexual haploid and asexual diploid stages.

在所有的高等植物和一些藻类会出现有性的单倍体阶段和无性的二倍体阶段交替的现象。

Research is being conducted on turning cellulosic waste such as corn stalks, corn cobs and algae or energy crops like switchgrass into viable sources of energy.

将例如玉米秸秆、玉米棒子和藻类这样的纤维素废物或像柳枝稷这样的能源作物转变为能源的可行来源，这样的研究正在进行中。

In previous management experience, it was found that a new desert governance is formed through microbial mucus conglutinate sand, or by algae, lichens and the moss Jiagen tied up and the formation of biological tie skin, a protective network to start, it can operate effectively constraining the flow, and thus play a dune-fixing role.

结合以前的治理经验，人们发现了一种新的沙漠治理方法，就是通过微生物形成的黏液粘连沙粒，或者被藻类、地衣和苔藓的假根捆绑起来，形成生物结皮，形成接近细沙的防护网，它能有效束缚沙粒流动，从而起到固沙作用。

The phytoplankton community was mainly composed of Cyanophyceae, Euglenophyceae, Bacillariophyceae, and Chlorophyceae, and the dominant species were Oscillatoria subtillissima, Dactylococcopsis irregularis, Euglena caudata, Melosira granulata, Cyclotella meneghiniana, Chlorella vulgaris, and Scenedesmus quadricauda. The main environmental factors affecting the distribution of phytoplankton species in July were ammonium-nitrogen, dissolved oxygen, water temperature, and total phosphorus, while those in September were pH, water temperature, dissolved oxygen, transparency, and total nitrogen. Water transparency and zooplankton were the main factors affecting the biomass of Cryptophyceae, Pyrrophyceae, and Bacillariophyceae; while nitrogen, phosphorous, and dissolved oxygen were the main factors affecting the biomass of Cyanophyceae, Euglenophyceae, and Chlorophyceae.

结果表明：调查期间共鉴定出浮游植物384种，隶属于8门，浮游植物密度范围为2.01×105～57.60×105 cells·L-1；群落组成以蓝藻、裸藻、硅藻和绿藻为主，主要优势种有细微颤藻、无常蓝纤维藻、尾裸藻、颗粒直链藻、梅尼小环藻、普通小球藻、四尾栅藻等；7月影响浮游植物分布的主要环境因子依次为铵态氮、溶解氧、水温和总磷，而9月的pH值、水温、溶解氧、透明度和总氮含量对浮游植物的分布产生影响较大；其中，透明度和浮游动物量是影响隐藻、甲藻和硅藻藻类生物量的主要环境因子，而蓝藻、裸藻、绿藻主要受水体氮磷营养盐浓度和溶解氧的影响。

The coefficient of non-algal particulates is decreasing with the increase of wavelength, which can be described by exponential law.

非藻类颗粒物的吸收系数随着波长的增大而减小，可用指数衰减规律来描述；光谱斜率S较离散，但平均值与文献报道的一类水体S的平均值很接近；光谱截距ad0(λ0)随盐度增大而减小，二者有很好的线性关系。

其他的分类特征有藻类储藏物质的特征，细胞壁的类型，波动足的类型和数量，细胞超微结构，食物储藏的类型，生殖过程等。

In nature, some green algae can produce hydrogen after incubation under anaerobic conditions, during which hydrogenase is synthesized and activated.

自然界中存在于藻类和细菌中的氢酶是高效的催化氢气氧化和质子还原的氧化还原酶，在生物产氢和能量转换过程中发挥着重要的作用。

Analysis indicates that food habit of silver carp and algae size are two causes of different removal efficiency between cyanobacteria and green algae.

分析认为鲢的滤食选择和不同的藻类规格是对蓝藻和绿藻不同去除效率的原因。

During the HAB of Skeletonema costatum in Jiaozhou Bay in the summer of 1999, modified clays and PSAS were used to remove HAB organisms in the field. The items determined included removal efficiency of HAB organisms, suspended material, DO, COD and pH.

赤潮治理的现场模拟实验及环境生态效应在1999年夏季胶州湾中肋骨条藻赤潮的发生现场进行了改性粘土及PSAS对藻类去除率、悬浮物、DO、COD、pH等指标的影响研究。

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。
