杂质

The force for filtering and backwashing is from water press and pump pressure.The pressure in filtering chamber will keep same.The solution will be filtered out from inner chamber of filtering core.The solid impurity will remain on the inner surface of filtering coThe pressure difference between outer and inner chamber and.filtering resistance will be increase.

该机的过滤和反冲洗推动力均原水压头或泵杨程提供，系统滤腔的压力基本保持恒定，液体从滤芯的内腔向外流动，夹带的固体杂质被截流在过滤介质的内表面，引起内外腔压差升高，过滤阻力逐渐增大。

A group of tiny white inclusions, composed of minute hollow spaces, or very small patches of tiny crystals or other impurities that produce a cottony or clouded appearance in a n otherwise highly transparent diamond.

一群小小的白色包裹组成分钟空心位还是很小很小的结晶块或其他杂质，或出示绵云露面了氮否则高度透明的钻石。

The characteristics of cryptocrystalline magnesite ore in Bameng Magnesite Mine were discussed.

论述了巴盟菱镁矿的特点，隐晶质菱镁矿多为热液交代型超基性岩类矿石，其基质致密坚硬，微细嵌布，杂质含量高，且有广泛类质同象，难以实现矿物单体解离，实际分选困难较大。

This product selection Cynomorium Wang-class, quality of raw material, artificial shade, remove the impurities from Seiko cartoning, it retains the nutrition and ingredients previously.

本品选用王级锁阳，中上等原料，经人工阴干，除去杂质，精工装盒而成，使其保留了原由的营养和成份。

Sliding bearing not only pass working force,but also sustain high surface velocity,which require the material to have soft parts,in order to obtain fine working behavior and difficulty to damnify by extra impurity,and have hard parts to acquire fine wearability and fatigue strength.

由于滑动轴承既要传递作用力又要承受很高的表面速度，这就要求轴承材料既要具有软组分，以获得良好的运行性能，如磨合性、顺应性以及尽可能小的咬和倾向，且不宜被外来杂质所损伤；又要具有硬组分，以获得良好的耐磨性和抗疲劳强度。

The new technology of microwave-aided leaching lasts short time, consumes low energy and is convenient to controlling. The process of desiliconization will not bring any impurities because ground ore is added as neutralize agent and no precipitant is used.

微波辅助浸出工艺经历时间短，能耗低，易于控制，采用矿石作中和剂，而且不使用任何聚沉剂，所以除硅过程中不会增加杂质。

The sediments are detrital and largely of greywacke facies.

沉积岩为碎屑质，大部分属于杂质砂岩相。

It is nothing else than impurities prenatal inherent in ore that seriously affect the quality of the latter, which is formed as a result of geological vicissitudes including diastrophic movement, eruption of volcano, sedimentation, glaciations and weathering etc.

没有什么比矿石中含有的天然杂质更能影响矿石的品质了，这些矿石是由地质的变迁引起的，包括地壳运动，火山爆发，沉淀，冰河作用，风化作用等等。

It is nothing else than impurities prenatally inherent in ore that seriously affect the quality of the latter, which is formed as a result of geological vicissitudes including diastrophic movement, eruption of volcano, sedimentation, glaciation and weathering etc

矿石是随着诸如地壳运动，火山喷发，沉淀、冰河以及风化作用等地质运动而形成的。然而，对于矿石本身影响最严重的莫过于其本身所含有的杂质。

It is nothing else than impurities prenatally inherent in ore that seriously affect the quality of the latter, which is formed as a result of geological vicissitudes including diastrophic movement, eruption of volcano, sedimentation, glaciation and weathering etc., under the action of which pyrogenic rocks, volcanic complex, aqueous rocks, sedimentary rocks etc., come into being, some of which exist in a stage of symbiosis, the main cause of the absence of pure rocks in nature, wherein lies the reason for the need of separation technology and apparatus, namely, ore-dressing devices and equipment, so far impotent to meet the requirements of metallurgical industry the scientists make every endeavor to elevate to a new high by laser separation.

矿石中天然固有的杂质严重影响其后来的质量。矿石的形成是地质变迁的结果，包括地壳运动，火山爆发，沉积作用，冰河作用和风化等等，在这些作用下，生成了火成岩，火山杂岩，水成岩和沉积岩等，一些矿石是由于这些作用共同形成的，这就是自然界中没有纯净矿石的原因。由于这些原因的存在，需要用分离技术和器械，也就是矿石加工设备对矿石进行的分割，迄今为止这些矿石加工设备已经不能够满足冶金工业的需要，科学家们力图用激光把冶金工业提高到一个新的水平。

In the negative and interrogative forms, of course, this is identical to the non-emphatic forms.

。但是，在否定句或疑问句里，这种带有"do"的方法表达的效果却没有什么强调的意思。

Go down on one's knees;kneel down

屈膝跪下。。。下跪祈祷
