| 释义 | lubricant noun[ C or U ] uk /ˈluː.brɪ.kənt/ us /ˈluː.brə.kənt/(informallube) a liquid such as oil that is used to make the parts of an engine move easily together, or a substance put on any surface to help it move more easily against another one润滑油;润滑剂 Right now, most industrial lubricants are made with oil, but because using oil in this way is not good for the environment,inventors are developing water-based lubricants. Water is also used in industry as a lubricant – something that can help prevent machines from wearing out when their parts move against each other. lubricant | American Dictionarylubricant noun[ C/U ] us/ˈlu·brɪ·kənt/(infmllube, us/lub/) a substance that is used to make parts move easily Examples of lubricantlubricant While manipulating the spermatophore, the male also secretes saliva, which is believed to serve as a lubricant. Thus, velocity profiles show that the lubricant does not support the shear effects at all. To minimize contamination problems for geochemical and isotopic analyses, we avoided the use of drilling lubricants containing organic materials. The task is not simple, as the production of the lubricant requires collective action of the dense bacterial population that the food-depleted substrate cannot sustain. Of course, weak consensus is the lubricant of choice. I do not deny that emotions also play a part in negotiations, but their role is only that of a lubricant. However, in some applications, the lubricant cannot be considered as a single fluid and a multifluid approach has to be introduced. Figure 7 shows that the flow is stable when the lubricant is heavier than the core fluid and unstable when lighter. Thin films are also used as lubricant layers for the flow of crude oil in pipes and channels. First, the envelope of the lubricant is marked on the imaginary hexagonal mesh. Capillary instability is rapidly stabilized by using heavy lubricant. The fuels and lubricants required for the growing national machine park were mostly imported as well, as was the bulk of fertilisers and irrigation equipment. Frequent use of topical lubricants together with antibiotic drops or ointment for any associated bacterial contamination will relieve most symptoms. This suggests mainly undegraded light aviation fuel mixed with heavier fuels and lubricants. Against this, however, greater skill, ingenuity and manpower was necessary to maintain and operate an ageing machine park short on parts, lubricants and other essentials.
