生长水中的

The results showed that the sludge settled properly at a influent BOD/P of 100/0.8. When the BOD/P was 100/0.6 and 100/0.3 respectively, an excessive growth of viscous Zoogloea with high moisture content was observed and non-filamentous bullring occurred. When the value of influent BOD/P was 100/0.4, more serious non-filamentous bulking occurred. Furthermore, under the condition of phosphorus deficiency the effect of microorganism on the nitrogen and phosphorus sources utilization rate were also studied in the experiments.

结果表明在进水中BOD/P为100/0.8以上的条件下，污泥的沉降性能良好；当进水中BOD/P分别为100/0.6和100/0.3时，出现高含水率的黏性菌胶团过量生长的现象，发生非丝状菌膨胀；在进水中BOD/P为100/0.4的条件下，发生更严重的非丝状菌膨胀，试验中还研究了磷缺乏条件下微生物对氮源和磷源利用率的变化。

They often resemble plants and are found mainly in marine or fresh-water habitats, although some algae are terrestrial.

藻类在自然界几乎到处都有分布，主要是生长在水中，也有陆生的。

Light and the presence of nutrients in the surface waters make phytoplankton growth possible.

光和地表水中养分的存在使浮游植物生长成为可能。

The aim of the study was to compare limiting effects of various nutrients on bacterial regrowth in drinking water.

［目的］比较各种营养元素对饮用水中细菌再生长的限制作用。

The microorganism method to solves the landscape hydrophila group entrophication has the good function,is obviously degenerate the water body COD,also can suppress the growth of the chlorophyceae plant effectively;④Chemistry method maintenance water quality may oxidize effectively, degenerate the pollutant and some organic matter in water,can effective kill the algae;⑤The clear silt can eliminate the death algae and each kind of organic and inorganic substance,thoroughly eliminate the environment which the algae grow,therefore the clear silt to algaes government is the very thorough means.

微生物法对解决景观水体的富营养化有较好的作用，对水体COD的降解作用较明显，能够有效抑制绿藻类植物的生长；④化学方法维护水质可以有效氧化、降解水中污染物和一些有机物质，能够有效的杀灭藻类；⑤清淤能够把死亡的藻类和各种有机和无机物质清除掉，彻底清除藻类生长的环境，所以清淤对藻类的治理是很彻底的办法。

Xerophytes tend to have thick cuticles, and dry conditions often induce cuticular thickening.

角质层的厚薄因植物的种类和生活环境而异，生长在干燥和阳光充足环境下的植物有较厚的角质层，而生长在水中或阴湿环境下的则较薄。

The comparative experiments of rearing Penaeus vanname larvae fed the microencapsulated diets and micro-partical diets of "OK" brand and a searies of microgranular diets of "Bonasse" brand was performed. Two brands of diets are respectively formulated with rotifera at percentage of 70%, 80%, 90% and 100%. During the nursery period, the water quality factors such as the concentrations of NH3-Nt, NH3-Nm, NO2-- N, COD and main planktons were tested to find out their change regulation and the influence on survival rates and metamorphic rates of shrimp larvae.

本文利用欧开牌微胶囊饲料、微粒饲料和博尚牌系列微型饲料作为对虾育苗饲料，分别以70％、80％、90％和100％的比例与卤虫活饵料配合来培育凡纳对虾幼体，通过对凡纳对虾幼体有关生长发育指标的对比以及对育苗期间水中总氨氮(NH_3-N_t)、非离子氨氮(NH_3-Nm)、亚硝酸盐氮(NP_2~--N)、化学耗氧量和主要浮游生物等水质因子进行检测，找出它们的变化规律并比较上述饲料对幼体生长发育、成活率、变态率和育苗效果的影响。

Large amounts of organic material may support substantial populations of nuisance organisms, such as filamentous bacteria (e.g., Sphaerotilus natans), that can clog water supply screens and that look and smell objectionable.

大量的有机物物质会促使实际存在的且令人讨厌的有机物的生长，（例如，漂浮在水中的水苔），它能阻止水的流动象静止的隔板一样，并且看起来，闻起来令人感到不快。

Just like a red, blue, or white lotus — born in the water, grown in the water, rising up above the water — stands unsmeared by the water, in the same way I — born in the world, grown in the world, having overcome the world — live unsmeared by the world.

就像一朵红色、蓝色或白色的莲花──它生於水中、长於水中、矗立於水面之上──而不被水所染污。同样地，我出生在这世间，生长在这世间，超越了这个世间──而不被这世间所染污。所以，婆罗门！

The long-term and short-term effects of different propionic/acetic acid ratio and initial pH on the anaerobic and aerobic transformations of GAOs were studied.

2在丙酸和乙酸的碳摩尔浓度相同的情况下，GAOs吸收乙酸的速率较快，且在乙酸浓度适宜的情况下，GAOs对乙酸的吸收不需要长期驯化，短期提高进水中的丙酸量可抑制GAOs的生长。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
