The number of autoterophic bacteria were significantly lower than the heterotrophic bacteria. Majority of 21 strains of heterotrophic bacteria that isolated from water body were Pseudomonas. Majority of 25 strains of heterotrophic bacteria isolated from sediment were bacillus, microccus and Pseudomonas.Three genus of autotrophic bacteria were sulphuret bacteria, nitrify bacteria and nitrosobacteria that were capable of oxidizing H2S, S, FeS, oxidizing NH3 to NO2 and NO2 to NO3 respectively.

试验稚鳖池水中共分离出21株异养细菌，其中优势菌为假单胞杆菌属细菌；底泥中共分离出25株异养细菌，其中优势菌为芽胞杆菌属细菌，微球菌属细菌假单胞菌属细菌，三种自养细菌分别为具有氧化硫化氢、元素硫或硫化亚铁的硫细菌；具有氧化氨为亚硝酸的亚硝化细菌和能将亚硝酸进一步转化成硝酸的硝化细菌。

Because you know they can't be that evil (you have been warned!). Because it is a carnivorous plant most people can grow like normal garden plants. This is definitely not a house plant. Ibicella and Proboscidea should be planted in a garden or a very large pot. No special soil is required.

单角胡麻与角胡麻属是少数可以像一般园艺植物那样栽培的食虫，但是它们可不适合种在屋子里，最好可以种在庭院，或者用很大的盆子种。

TF primary extracts condensate used alone or used with the general stored grain chemistry protect pharmaceutical to get the experimental treatments. Adopt filter paper medicine membrane method and grain mixed medicine method to seeking TF plant single pharmaceutical and the extender, screen out two kinds of emulsion Basuling-1, Basuling-2 and one powder Basuling powder have better prevent and cure result to target pest Sitophilus zeamais Motschusky and Rhizopertha dominica Fabricius.

TF植物性物质单用或与常用的化学防护剂混配，采用滤纸药膜法和小麦拌药法对优选TF植物单剂和混配剂的筛选，筛选出了对靶标害虫玉米象和谷蠹有较好防治效果的乳油两种巴素灵1号、巴素灵2号和粉剂巴素灵粉。

In the second case, the voter's COR output is derived from the absence of pilot tones which each remote receiver produces unitl it becomes unsquelched.

第二种方式，比选器的COR输出是来自于不存在的由每一台远端接收机产生的测试单音，直至该单音成为非静噪输出。

Seventeen resins were selected to compare their performances in adsorbing and desorbing monosubstituent in the mixture. Experimental results showed that HZ-841 resin possessed higher selectivity and desorption capacity.

比较了17种树脂对β-环糊精单甲苯磺酰化产物的吸附特性，确定了大孔弱极性吸附树脂HZ-841对单取代物具有较高的吸附选择性和良好的脱附性能。

The combined analysis with cpSSR and chloroplast non-coding gene sequences found that there were several disperse glacial refugia within species of Dipteronia,the main glacial refugia for species D.dyerana was its recent distribution southeastern-yunnan province,and with abroad distribution,the main glacial refugia of D.sinensis were Qinling mountains,Daba mountains,Funiu mountains, Wuling mountains and Shennongjia mountains.

叶绿体DNA单倍型分析表明金钱槭属内金钱槭和云南金钱槭种间无共享单倍型，叶绿体SSR标记和基因序列分析表明：金钱槭属植物存在多个分散的冰期避难所，其中云南金钱槭主要避难于其现今分布的云南省东南部地区，而金钱槭由于其分布区比较广泛，主要的避难所有秦岭山脉、大巴山山脉、伏牛山山脉、武陵山脉、神农架山脉等。

This article discusses the tone sandhi pattern of AA""and ABB in Datong dialect ,argues that there exist in the two sandhi patterns the underlying representations which adjust during the transformations to the surface representations according to the tone of the first syllable.

通过分析大同方言单音节形容词AA儿式和ABB式的连调式，提出两种连调式都在底层有一个统一的模式，在生成过程中以首字的单字调为条件进行调整，这种调整可以用强制非恒原则来解释。

But each different language has its own sound change pattern. The tone is changed in most languages.

分布最广的是ABB式的叠音后缀，15种语言有此形式；其次是AB式单音节后缀和ACD式等双音节后缀，分别在9种和10种语言中存在。

This paper makes use of PID control, Fuzzy- PID control based on single parameter these two control strategies to simulate the systems model. Compared with common vehicle, the results of simulation show that the vehicle equipped with the electromagnetic power steering system has better yaw velocity frequency response characteristic under condition with step input of steering wheel, so it has more betterhandling stability; Compared with PID control strategy, the results show that the Fuzzy-PID control strategy has the advantages, such as response fast, stabilize itself quickly and less over-altitude.

本文使用了PID、单参数自整定Fuzzy-PID两种控制策略对系统模型进行控制，仿真结果表明：相对于普通汽车，装有电磁式助力转向系统的汽车在方向盘转角阶跃输入的情况下，汽车横摆角速度频率响应特性更好，因此具有更好的操纵稳定性；而相对于采用PID控制，采用单参数自整定Fuzzy-PID控制又可以使系统响应更迅速、超调量更小、稳定更快。

The properties of the fundamental space-filling mode are analyzed in detail by the PWM, and give a criterion of SPSM PCFs.

在单模单偏振光子晶体光纤方面，提出了一种新型的结构，采用平面波展开法对基空间填充模进行了深入的分析，以此模式为基准判定单模单偏振的区域。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
