它生产了数千种不同的 wouldhave been little difficulty definingwhat constituted chemicalindustry since only verylimited range wereclearly chemicals,在本世纪初，要定义什么是化学工业是不太困难的，因 为那时所生产的化学品是很有限的，而且是非常清楚的化学品 thereforeapparent itsdiversity closelinks manyareas otherindustries, simpledefinition chemicalindustry.因此，很明显，由于 化学工业经营的种类很多并在很多领域与其它工业有密切的联 系，所以不能对它下一个简单的定义。 mostconcern chemicalindustry?Page16 productdevelopment (ii) process development (iii) process improvement applicationsdevelopment basiccomponents typicalchemical process?

To commercialize laboratorychemistry, chemicalengineer development,design, construction, operation, sales, research.要把实验室研究商业化，化学工程师要参与进行开发、设计、建筑、操作、销售和研 究工作。 fermentationmethods?Page39 veryselective somechemical which structurallyvery complex thereforeextremely difficult multi-stagesynthesis easilymade majorcost item industrialchemical processes spent?page45 majorcost item industrychemical process originalpurpose basicchemical industry?page51 basicchemical industry findeconomical ways turningraw materials usefulintermedieates canyou write down basicreactions brineelectrolysis Anode2Cl- －2e- Cathode2H2O 2e-?H2 III.Translate followingsentences thereforeapparent itsdiversity manyareas otherindustries, simpledefinition chemicalindustry. 因此很显然，由于其操作的多样性及与其他诸多领域的紧密联系，化学工业很难得到一个简单的定义。

物质的溶解度对于化学和化学工业都很重要化学工程与工艺专业英语考试，在固体物质的重结晶和分级结晶、化学物质的制备和分离、混合气体的分离等工艺中都要利用物质溶解度的差别。旋流除砂器是根据流体中的固体颗粒在除砂器里旋转时的筛分原理制成，集旋流与过滤为一体，在水处理领域实现除砂、降浊、固液分离等效果显著。切向流过滤是目前普遍采用的一种膜分离技术，属于分子量级别的过滤化学工程与工艺专业英语考试，一般截留分子量范围为：1～1000kd，能对溶液中的极小颗粒及可溶性分子进行分离，切向流过滤通常只能分离哪些大小相差3-5倍以上的分子，而不适合分离大小相似的分子。
