查询词典 low level

The samples'concentration level is ng/L, meanwhile, which doesn't go beyond the national standard "Environmental quantity standards for surface water-GB 3838—2002"and "Drinking water quality criteria standard GB5746-85". The study shows that the water purification palnts in The Three Gorges Reservoir Area especially those raw water from Yangtze River and Jialingjia River is safe enough for drinking and its level is low. After having tested and analyzed the raw water samples of 6 water purification plants in Three Gorges Reservoir Area, I have found several variety of PAHs and PAEs. Of which, naphthalene, fluoranthene and DEHP are priority pollutants firstly listed by SEPA..

按照《地面水环境质量标准GB 3838—2002》和《生活饮用水水质标准GB5746-85》对有机氯农药的规定，上述6 个水厂均未超标，表明三峡库区城市给水厂特别是以长江、嘉陵江为水源的水厂，其有机氯农药污染较轻，饮用水水质安全。6 个给水厂的原水均检出含有多种PAHs 和PAEs，其中包括有我国国家环境保护总局首批公布的水中优先检测污染物萘、荧蒽、DEHP。

If limitative pay is very low, good outside member look down on CBA at all, restricted the level of league matches on certain level.

假如限制的薪水很低，好的外员根本看不起 CBA，就在一定程度上制约了联赛的水平。

In this research, we consider that the predominant bacteria in low temperature wastewater treatment in winter were cold-adapted microorganisms, the number of which increased as the temperature dropped more and more, but rarely high up to the number of mesophilic bacteria in normal temperature due to its low growth rate and the restriction of ecological factors, so that the total number and activity level of microorganism in activated sludge decreased.

随着污水温度的降低，污泥中冷适应微生物的数量逐渐增加，但由于冷适应微生物的生长速率相对较低，且容易受到各种生态因子的抑制作用，其数量无法达到常温下中温微生物的水平，使得污泥中微生物的总体数量和活性降低。

The analyses of the meterological and oceanographical data from seriel observations aboard R/V Xiangyanghong 5 during the voyage of joint AMEX experiment by Australia,China and the United States show that (1) there is high level of humidity within middle and low layers of troposphere at the initial stage of a typhoon's formation,and once a typhoon has fully developed,the highest level of humidity remains within middle layer of tropisphere;(2) although small vertical wind shear is a requisition for a t...

对中、美、澳三国AMEX试验期间&向阳红5号&定点观测到的气象和海洋资料分析得出：①台风形成前，大气整个中、低层空气湿度较大，台风一旦形成，大气湿度最大层主要集中在中空；②风速垂直切变小，对形成台风是一个必要条件，但并非整个对流层风速切变都小，而且不同地区形成的台风，风速切变状况是不同的；③厄尔尼诺年南半球与北半球对应位置同期的θ_G、θ_8、Q_b相差不大，但是南半球的θ_c较北半球的大。

Third, this dissertation attempted to set up the statistical indicator of urban low-rent housing security relative level, and using of this indicator, priorly exert empirical research on the low-rent housing security implement conditions of all regions of the country.

第三，论文尝试性地设置了廉租住房保障相对水平的统计指标，运用这一指标，较早地对全国各地区的廉租住房保障实施状况进行了实证研究。

There are a few defects in existing processes of biomass gasification, for example using air as gasifying medium, N2 and tar content of the gas is high, and the calorific value is as low as 5000kJ/N in3. The technology of a circulating fluidized bed is still tentative at laboratory level. Through direct pyrolyze biomass, we can get product gas with high heating value (l4000kJINm3), but gas yield ratio is low (O.35m3/kg).

目前的生物质热解气化技术的现状是：以空气为气化剂的气化方式，得到的气体N_2和焦油含量高，热值一般在5000kJ/Nm~3左右；流化床气化工艺操作复杂，推广应用存在较多困难；直接干馏热解，虽气体的热值高（14000kJ/Nm~3），但产气率低（0.35m~3/kg）。
