chemical
chemical: [16] Essentially chemical, and the related chemistry and chemist, come from alchemy with the initial al- dropped. Alchemy itself is of Arabic origin; al represents the Arabic definite article ‘the’, while the second element was borrowed from Greek khēmíā ‘alchemy’. Loss of al- seems to have taken place originally in French, so the immediate source of the English words was French chimiste and chimique (whence the now obsolete English chemic, on which chemical was based).At first this whole group of words continued to be used in the same sense as its progenitor alchemy; it is not really until the 17th century that we find it being consistently applied to what we would now recognize as the scientific discipline of chemistry.=> alchemy

10. It is possible to create a persona that represents the needs of several user roles (for example, in designing a mobile phone, a traveling salesperson might also represent the needs of a busy executive who’s always on the road), and it is also possible that there are several people in the same role who think and act differently (perhaps a procurement planner in the chemical industry thinks about her job very differently from a procurement planner in the consumer electronics industry).
创建一个代表不同用户角色需求的人物角色是可能的，比如在设计某款手机时，一个经常出差的销售人员是可以代表这一个同样经常在路上的总裁的需求。 同样，一些身居同样角色的人们，他们的思维方式和行动方式也有可能是不同的。 比如，在看待其工作的思维方式上，化工行业的采购经理和在消费电子业的采购经理可能是非常不同的。
