运用概念隐喻理论对英语"时间"谚语进行分析,将英语"时间"谚语划分为四组隐喻概念:Time is money(时间是金钱)、Time is human/life(时间是有生命的人)、Time is a concrete object(时间是具体的实物)、Time is a moving object(时间是运动的物体),论述了这些隐喻概念表达都呈系统性,指出转喻是时间概念化的一种方式和过程,它是通过时间与事物甚至有生命的人之间的转喻联系实现的。
This is an analysis of English time proverbs from a theoretical perspective of Conceptual Metaphor . The results show that English time proverbs can be categorized into four groups of concepts: Time is money;Time is human/life;Time is a concreteobject;Time is a moving object .They are systematic .The conceptualiza-tion in English time proverbs is also a metonymic process ,which is realized by the metonymy between time and object , time and human or life .

目的观察real time PCR在血流感染病原体检测中的敏感性和特异性,并与常规血培养对比,探讨其临床应用价值。方法以该院各临床科室收集的108份脓毒血症患者血液标本进行real time PCR检测,同时进行常规血培养,比较两种方法的特异性和敏感性。结果 108份标本当中,两种方法检测出12种病原微生物。Real time PCR共检测出阳性标本25份,阴性标本83份。其中与血培养共同阳性标本9份,共同阴性标本78份。两方法的一致性为80.6%。Real time PCR的阴性预测值是0.94,敏感性64%,特异性83%。16例标本real time PCR阳性而血培养阴性,5例标本血培养阳性而real time PCR阴性。同时,有2病标超出real time PCR的检测范围,而血培养阳性。此外,real time PCR无法检测光滑念珠菌。结论 real time PCR虽然能快速检测血液感染中病原微生物,但依然不能完全替代血培养。

In this paper, the northward jump time of the western Pacific subtropical high(WPSH) is defined and analyzed on the interdecadal timescale. The results show that under global warming, significant interdecadal changes have occurred in the time of the WPSH northward jumps. From 1951 to 2012, the time of the first northward jump of WPSH has changed from "continuously early" to "continuously late", with the transition occurring in 1980. The time of the second northward jump of WPSH shows a similar change, with the transition occurring in 1978. In this study, we offer a new perspective by using the time of the northward jump of WPSH to explain the eastern China summer rainfall pattern change from "north-abundant-southbelow-average" to "south-abundant-north-below-average" at the end of the 1970 s. The interdecadal change in the time of the northward jump of WPSH corresponds not only with the summer rainfall pattern, but also with the Pacific decadal oscillation(PDO). The WPSH north

In this article, we concern the motion of relativistic membranes and null membranes in the Reissner-Nordstrm space-time. The equation of relativistic membranes moving in the Reissner-Nordstrm space-time is derived and some properties are discussed. Spherical symmetric solutions for the motion are illustrated and some interesting physical phenomena are discovered. The equations of the null membranes are derived and the exact solutions are also given. Spherical symmetric solutions for null membranes are just the two horizons of Reissner-Nordstrm space-time.
