杂质

Gold and silver are refined by fire. Furnaces and crucibles withstand extremely high temperatures as impurities are eliminated.

金子和银子都是用火来熬炼的，炉和鼎要受得起极高的温度，才能除去杂质。

However, flow cytometers suffer from their intrinsic inability to tolerate large particles that associate with the isolated nuclei. A plant nuclei suspension can often contain a high level of crystalline calcium oxalate that blocks the fluidics system of the flow cytometer.

但是植物的细胞核悬浮液中常含有草酸钙结晶，样品中过大的杂质颗粒常会堵塞流式细胞仪吸取样品的管子。

Therefore procaine hydrochloride, ampicillin sodium and dapsone can be determined in the range of visible light.

该反应将药物的最大吸收波长由紫外区红移至可见区，避免了紫外区杂质的严重干扰。

MethodsDross were purged from Luohanguo extract with water by ZTC1+1 clarifier, mogroside were isolated by D101 macroporous resin, decoloured on a D301R weak alkaline ion exchange resin.

方法用ZTC1+1澄清剂除去罗汉果水提液中的杂质，以D101大孔吸附树脂分离罗汉果甜苷，D301R弱碱性离子交换树脂脱色。

Strong adsorbents such as zeolites and activated alumina may not work well as it will be harder to desorb impurities from them.

沸石和活性氧化铝之类的强吸附剂可能效果不好，因为杂质难以从这些强吸附剂中解吸附。

If a crystal is grown very rapidly so that impurities, such as microorganisms, do not have time to be desorbed, they may be entrapped within the growing crystal. Recovery would be impossible with

如果晶体生成非常迅速，使得诸如微生物之类的杂质没有时间得到充分解吸附，微生物可能在生长的晶体中被捕获。

The method has the advantage of automatic desorbing and analyz...

结论该方法具解吸和分析检测过程自动化，操作简便快捷，检测灵敏度高，杂质干扰少等特点，可用于实际火场中汽油、煤油和柴油残留物的检测。

It imply various complicated composition in the fuel, at burnable after produce various harmful material, even not the fuel with miscellaneous quality attains the complete combustion, also wanting to produce the water and carbon dioxides, positive because the fuel combustion makes the carbon dioxide in the atmosphere density increased continuously, breaking the balance of the nature carbon dioxide, to go to and may cause" green house effect", cause the Earth air temperature rise.

燃料中含有各种复杂的成分，在燃烧后产生各种有害物质，即使不含杂质的燃料达到完全燃烧，也要产生水和二氧化碳，正因为燃料燃烧使大气中的二氧化碳浓度不断增加，破坏了自然界二氧化碳的平衡，以至可能引发&温室效应&，致使地球气温上升。

A:The content increment of the carbon dioxide in the atmosphere: It imply various complicated composition in the fuel, at burnable after produce various harmful material, even not the fuel with miscellaneous quality attains the complete combustion, also wanting to produce the water and carbon dioxides, positive because the fuel combustion makes the carbon dioxide in the atmosphere density increased continuously, breaking the balance of the nature carbon dioxide, to go to and may cause" green house effect", cause the Earth air temperature rise.

一：大气中二氧化碳的含量增加：燃料中含有各种复杂的成分，在燃烧后产生各种有害物质，即使不含杂质的燃料达到完全燃烧，也要产生水和二氧化碳，正因为燃料燃烧使大气中的二氧化碳浓度不断增加，破坏了自然界二氧化碳的平衡，以至可能引发&温室效应&，致使地球气温上升。

The paper introduces briefly to adjust and control some parameters,such as surface dopant concertration to attain necessary...

简单介绍通过调整和控制表面杂质浓度等参数，得到所需的灵敏度温度漂移曲线。

Breath, muscle contraction of the buttocks; arch body, as far as possible to hold his head, right leg straight towards the ceiling (peg-leg knee in order to avoid muscle tension).

呼气，收缩臀部肌肉；拱起身体，尽量抬起头来，右腿伸直朝向天花板（膝微屈，以避免肌肉紧张）。

The cost of moving grain food products was unchanged from May, but year over year are up 8%.

粮食产品的运输费用与5月份相比没有变化，但却比去年同期高8％。
