查询词典 be present

The present invention relates to a process for rapid solution synthesis of a peptide, the process comprising repetitive cycles of steps-: a coupling step, using an excess of an activated carboxylic component to acylate an amino component, a quenching step in which a scavenger is used to remove residual activated carboxylic functions, wherein the scavenger may also be used for deprotection of the growing peptide, one or more aqueous extractions and optionally, a separate deprotection step, followed by one or more aqueous extractions, characterised in that the process comprises at least one step, referred to as step, in which an amine or a thiol comprising a free anion or a latent anion is used as a scavenger of residual activated carboxylic functions.

At present the mechanism of endangered species mostly confined to the morphology point of view, few physiological point of view of ecology, the lotus leaf fern Adiantum growth conditions of the study also stay in more qualitative analysis, there are few quantitative analysis of its optimum growth environment , The experimental use of morphological and physiological ecology of the idea and will use the components of the research methods, to be a long time to further explore their own independent development of plant taxonomy, morphology, physiology, ecology and other subjects the intrinsic link between , With a view to a new high on the survival of endangered species, adaptation and evolutionary mechanism.

目前对物种濒危机理的研究大都局限在形态学角度，很少有生理生态学角度的研究，对于荷叶铁线蕨生长条件的研究也多停留在定性分析上，很少有定量分析其最适生长环境，本实验采用形态学与生理生态学结合的思想，并将采用构件理论的研究方法，拟进一步探讨长期以来各自独立发展的植物分类学、形态学、生理学、生态学等学科之间的内在联系，以期能在一个新的高度上探讨濒危物种的生存、适应对策和进化机制。

If any person B, in any imaginable situation at any time t', were warranted in believing that at an earlier time t some specified person A sincerely made the statement "My present afterimage is red," and also that A did not immediately revoke or otherwise discredit it, then B would not be warranted at t' in believing that at t A had an afterimage that was not red.

这里排除A所可能发生的"使用和表达错误"，A确实有红色的余象（ afterimage ：视觉刺激结束后持续的图像）；而且这里不仅要表明B没有证据表明A的陈述是错的，而且之所以如此是因为A的陈述意味着被描述为红的是余象而非其他，不是一个反思，不是一个玻璃杯上的红点，不是墙上的红斑。B不能矫正的不是A的陈述，而是A的余象。
