Currently,construction of facilities in the Arctic is carried out on sand islands,but there are limitations for remote coastal conditions.These restrictions are associated with the lack of quarries with construction sand in the immediate vicinity of the w
板内中小滑移距走滑断裂因产状高陡、变形微弱,其地震识别与地质解析一直以来是构造领域研究的难点和重点.为加深对此类走滑断裂发育特征的认识,以塔里木克拉通盆地内部顺北4号走滑断裂为例,利用最新采集处理的高精度三维地震资料,对其空间结构及演化过程进行了精细解析,认为顺北4号断裂具有“平面分段多样性、纵向变形差异性、构造演化多期性”的特点,石油地质条件优越.研究结果表明:顺北4号断裂横跨塔北隆起、顺托果勒低隆起、塔中隆起3大构造单元,全长超过280 km,基于走向变化可将三维研究区内的顺北4号断裂划分为南段(NE
发酵蔬菜作为传统食品,是蔬菜加工行业中的一个重要组成部分,发酵蔬菜的营养价值也越来越受到消费者的重视,随着农产品加工技术的进一步研究和深入,蔬菜发酵的功能性分析也成为学者们的研究热点之一.该文主要综述了近年来发酵蔬菜的抗氧化性的国内外研究现状、影响发酵蔬菜抗氧化活性的物质、检测方法以及不同外源活性物质的加入对发酵蔬菜抗氧化性的影响研究,对影响发酵蔬菜抗氧化性的各方面的因素进行总结和概述,为发酵蔬菜的抗氧化活性研究提供一定的理论依据及参考.
