低降

It has good water-loss controlling ability, especially PAC is highly effective drop filter-loss agent. Even added at Iow quantity, it can control water loss at very high level, but does not affect slurry' s other characteristics.

具有较高的失水控制能力，特别是PAC是高效的降滤失剂，在较低的加量下，就可以把失水控制在较高的水平，而不影响泥浆的其他性能。

For example, production costs for PV cells have come down steadily over the last decade to between 50 cents to 30 cents per kilowatt-hour, and lower for some applications.

举例来说，在过去十年中，光伏电池的生产成本一直呈下滑趋势，由每千瓦小时的50美分降到30美分，而且对于一些用途，成本更低。

Its absolutely out of the question for us to reduce our price to your lev el.

我们不可能将价格降到你方所要求的那样低。

The results indicate that finishing temperature and coiling temperature have more affects on yield ratio of HP345 steel.Yield ratio will increase when finishing temperature and coiling temperatrue reduced;It is obviously decreased when coiling temperature is equal to 650℃;it is obviously increased while coiling temperature is reduced to 580℃;it is lower and has less variation while coiling temperature is between 610℃ an...

结果表明，终轧温度和卷取温度对HP345钢的屈强比都有较大的影响，降低终轧温度和卷取温度，均使HP345的屈强比升高；卷取温度为650℃时，屈强比明显降低；而卷取温度降至580℃时，屈强比明显升高；卷取温度在610℃~630℃区间变化时，屈强比较低而且变化不大，同时钢具有较高强度。

If the pressure drop across diffuser restricted, have to choose a lower Mach number.

如果扩散器两端压降受限制，只好选择较低的马赫数。

Introduced the structure arrangent,refitting vehicle,decreasing noise and ventilation,heat emittion,etc of 90kW microbus for low-noise mobile electric power station and supplied some technical basis for this type electric power station s research and production in future.

介绍了90kW面包车型低噪声移动电站的结构布置、车辆改装、降噪及通风散热等，为今后该类型电站的研制和生产提供了一定的技术依据。

The Lower/Upper Cretaceous boundary in Songliao Basin is,therefore,between the Quantou and Denglouku formations,instead of between the Quantou and Qingshankou formations.2.The dark mudstones and shales in the Member 1 of Qingshankou Formation are of high organic carbon and low diasteranes contents.Organic geochemical characters are illustrated by biomarkers of 28,30-bisnorhopane and gammacerane,and positive excursion of kerogen isotopes.It is suggested that the dark mudstones and shales in the Member 1 of Qingshankou Formation are the products of lake anoxic period.It corresponds to the oceanic anoxic event at Cenomanian-Turonian boundary in Cretaceous.3.Based on the study of biostratigraphy,chronostratigraphy,magnetostratigraphy and event stratigraphy,a correlation of the lacustrine sequence to marine standard has been proposed,i.e.,the Quantou Formation corresponds to Cenomanian stage,Qingshankou Formation correlates to Later Cenomanian-Early Turonian,Yaojia Formation to Later Turonian-Coniacian,Nenjiang Formation to Santonian-Campanian.Sifangtai and Minshui Formations to Maastrichtian. 4.Analysis of lithology,lithofacies and microfossils of Cretaceous in Songliao Basin, shows that shore and shallow lake facies yield the most abundant microfossil groups,and the predelta and deltaic distributary plain facies rich in fossils as well.In the shore and shallow lake areas during the high level periods(such as Qingshankou and Nenjiang sedimentary periods),the lacustrine biota are of high diversity and high abundance.

因此，松辽盆地上、下白垩统的界线应在泉头组的底界，即泉头组与登娄库组之间，而不是泉头组的顶界。2、青山口组一段黑色泥岩、页岩具有有机碳含量高、重排甾烷含量低，生物标志物出现28，30—双降藿烷和伽马蜡烷，干酷根碳同位素具有正向偏移等有机地球化学特征，表征为青山口组一段黑色页岩、油页岩是古湖泊缺氧事件的产物，它对应于白垩纪古海洋Cenomanian—Turonian期界线附近缺氧事件，二者具同步性。3、通过生物地层学、年代地层学、磁性地层学和事件地层学研究，认为泉头阶大体相当于Cenomanian阶，青山口阶相当于晚Cenomanian—早Turonian阶，姚家阶对应于晚Turonian—Coniacian阶，嫩江阶对应于Santonian—Campanian阶，四方台阶和明水阶相当于Maastrichtian阶。4、通过对松辽盆地上白垩统的岩性、岩相及微体化石分析，认为滨浅湖相是微体生物群最为发育的相带，其次为三角洲前缘相和三角洲分流平原相。

Because of the low test current level used, a very sensitive voltmeter is required to measure the voltage drop, which is usually in the microvolt range.

由于所使用的测试电流很低，所以就需要非常灵敏的电压表来测量这种通常在微伏范围的电压降。

Guarantee accommodation in the midseason, at the same time we economize cost in the supply chain.

在运输的旺季保证舱位的同时，从供应链条重寻找节点努力把客户的物流成本降到更低。

Platelet counts were dropped dramatically in animals that received antibody injection within 4 h, maintained at the mini-mum level for a period of 44 h, started to rebound after 48 h, and reached to the maximum at 144 h (6 days). Final homeostasis reached at approximately 408 h (17 days), following a minor cycle of platelet number fluctuation.

模型小鼠在抗体注射4h血小板数量大幅降低，维持在低水平达44h，48h后开始恢复，至144h（6天）数量达到最高点，其后又经过一个小的降升循环，在408h（14天）后恢复到初始水平。

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。
