Hosts evolve defensive strategies to minimize the reproductive costs of brood parasitism,in turn,the hosts'defense promote the optimization of cuckoo parasitism strategies(Soler 2017).Recognizing foreign eggs and selectively removing them from the nest can minimize the fitness costs associated with rearing parasitic fledglings(Soler 2017).Since Rothstein(1971)first experimented with the addition of a model egg to a host nest in the early incubation period to study host egg recognition,the use of model eggs has become one of the most important methods for testing the egg recognition abilities of hosts(Hauber et al.2019).Some studies have looked at various egg colors and their effect on host egg rejection and found differential responses to egg colors(for more details,see Supplementary Materials),highlighting that more work needs to examine the effect of model egg color on host egg rejection behavior.

采用粉末冶金法制备铜/金刚石复合材料,研究不同含量活性元素Nb对铜界面改性的影响机制以及对铜/金刚石复合材料的热导率的影响,利用XRD、SEM、EDS和导热系数测定仪分析复合材料的界面和热导率。结果表明,随着Nb含量的添加,能够在烧结过程中形成碳化物界面层,铜和金刚石界面缺陷逐渐减少,界面结合逐渐转好。在1%的含量时,复合材料的热导率达到370.3 W/(m·K),相比纯铜/金刚石复合材料提高1.34倍,但当含量超过1 vol.%,碳化铌中间层变厚,由于碳化铌自身热导率较低,导致复合材料的热导率降低。

Many studies have been performed on diesel engine particulate matter emissions, but the influence of lubricants on emissions has only been considered a few times, and the effects of lubricant additives have yet to be investigated. We studied the influence of a pour point depressant additive （PPD） on particle emissions and particle size distributions from a four-cylinder turbocharged, inter-cooled engine with CF-4 15W-40 lubricant, using diesel or diesel containing the PPD, Changing the working conditions changed the number of particles emitted and the location of the peak particle size（s） emitted, The number of particles first increased and then decreased as the engine speed increased, Particle emissions were optimal at low engine speeds and high load, increasing with increasing engine speed,
