该研究建立了芦蒿废弃茎叶的UPLC指纹图谱及5个酚酸类成分的一测多评法(quantitative analysis of multi-components by single marker,QAMS)。采用Waters Acquity UPLC BEH C_(18)色谱柱(2.1 mm×100 mm,1.7μm),流动相为0.1%磷酸水-乙腈,梯度洗脱,流速0.3 mL·min^(-1),检测波长330 nm,柱温30℃,进样量2μL。对指纹图谱的数据进行相似度评价及聚类分析,确定13批次芦蒿废弃茎叶中的15个共有成分。以绿原酸为内参物,分别计算阿魏酸、异绿原酸A、异绿原酸B、异绿原酸C的相对校正因子,实现了芦蒿废弃茎叶中5个成分含量测定的一测多评法的建立。同时采用外标法测定此5个成分的含量,结果显示一测多评法与外标法测定结果无显著性差异。结果表明,不同品种和不同产地的芦蒿废弃茎叶中的酚酸类成分含量存在明显差异,且木质化后的芦蒿废弃物中的酚酸类含量较未木质化显著提升。综上所述,该研究建立的芦蒿废弃茎叶一测多评法能够快速准确、简便经济地用于芦蒿废弃茎叶中5个酚酸成分的含量测定,为芦蒿废弃茎叶的资源化开发利用奠定了基础。

The high prevalence of diabetes has become a major public health issue worldwide[1], particularly in middle-and low-income countries[2]. The prevalence of diabetes in China, the largest developing country,has more than quadrupled in recent decades, and many cases of diabetes are undiagnosed[3]. The problem with missed diabetes diagnoses is a challenge faced both by China and the rest of the world[4].

鳞翅目(Lepidoptera)尺蛾科(Geometridae)成虫多为中型蛾类,其幼虫称为“尺蠖”,是荔枝和龙眼梢期的重点防控对象之一。目前,我国已报道的危害荔枝和龙眼的尺蛾科害虫共有10种,广东省内常见的有8种,分别为:粗胫翠尺蛾Thalassodes immissaria、大造桥虫Ascotis selenaria、大钩翅尺蛾Hyposidra talaca、油桐尺蛾Biston(Buzura)suppressaria、波纹黄尺蛾Perixera illepidaria、樟翠尺蛾Thalassodes quadraria、荔枝青尺蛾Berta chrysolineata hainanensis和间三叶尺蛾Sauris interruptaria。至今,国内外围绕荔枝和龙眼尺蛾科害虫开展的研究报道仅为15篇,其中粗胫翠尺蛾最多(7篇),而为害较普遍的荔枝青尺蛾和间三叶尺蛾尚未见研究报道。本文基于文献检索结果,着重综述了粗胫翠尺蛾、大造桥虫、大钩翅尺蛾、绿额翠尺蛾Pelagodes proquadraria和油桐尺蛾5个尺蛾科优势种的研究现状,并且从农业防治、物理防治、生物防治和化学防治4个方面概述了国内外荔枝和龙眼尺蛾科害虫综合治理技术研究进展。目前,尺蛾科害虫的生物防治技术研究集中于天敌的保护利用、生物源农药和昆虫性信息素的开发与应用。至今,已有粗胫翠尺蛾、大造桥虫、槐尺蛾Chiasmia cinerearia和油桐尺蛾4种尺蛾的性信息素有效组分被成功鉴定。但当前针对尺蛾科害虫仍以化学防治为主,而且我国用于荔枝和龙眼尺蛾科害虫防治的杀虫剂尚无登记,对农技推广人员指导用药提出了巨大挑战。本综述旨在帮助广大科研工作者全面了解此类害虫的研究现状,以期为尺蛾科害虫的深入研究及综合防控新技术的研发提供参考。

The tafoni that develop in sandstone cliffs have attracted the interest of both scientists and the general public. A necklace-like tafone system, referred to here as beaded tafoni, has developed in the prominent cliffs of the Danxia landscapes within the Longhushan Global Geopark in the subtropical zone of South China. This paper presents a new model of the formation of this system of extraordinary beaded tafoni. The cliffs of the Danxia landscapes of the study area are composed of an alluvial conglomerate(i.e.,red beds). These Danxia landscapes have subrounded summits that are covered by vegetation and experience a nearly vertical water flow induced by gravity. Erosion and collapse of the outsized gravels and concentrated pebbles in the red beds give rise to the initial development of the beaded tafoni. The tafoni then become rounded and beaded as a result of reworking and decay by fluvial outwash. During storms, intense water flows run vertically down the cliffs and generate a whirling motion in the ***, the inside walls of the tafoni gradually become wider and smoother. During the late development stage, the beaded tafoni tend to become indistinct or disappear because of the interconnection of the tafoni and subsequent merging with the bedding-controlled cavities.

以某四冲程内燃机为研究对象展开研究,根据其油环和活塞结构特性、缸套表面润滑油分布建立油环流量平衡和力平衡方程。通过分析运行时润滑油的输送过程,以及油环上方环岸区域润滑油量的变化及其沿缸套自下而上的输送过程,得出如下结果:油环控制油环-缸套间润滑油的流动,使环岸区域在活塞向下行程时储存润滑油,并在活塞向上行程时将润滑油输送至活塞上止点,实现润滑油的输送,满足活塞在上止点的润滑要求。

为研究不同热杀菌条件对蒸排骨预制菜品质的影响,以猪肋排为原料,对比分析相同杀菌强度下不同杀菌条件(115℃/36 min、121℃/14 min、127℃/7 min)处理的蒸排骨预制菜的食用品质和营养品质。结果表明,杀菌强度为5 min时,随着杀菌温度的提高,烹饪值(cook value,C)不断降低,排骨肉色泽略有劣变,但嫩度和质地有所提升;营养损失率降低,其中127℃组的必需氨基酸总含量显著高于115℃组和121℃组(P<0.05),为9.73 g/100 g;总挥发性盐基氮(total volatile basic nitrogen,TVB-N)含量从115℃时的8.66 mg/100 g显著下降到127℃时的7.36 mg/100 g(P<0.05)。电子鼻主成分分析可以反映不同杀菌条件下挥发性气味上的差异,随着杀菌时间的延长,排骨中甲基类、硫化物、醇类和醛酮类等风味物质的响应值不断增大。总体而言,适当提高杀菌温度、缩短杀菌时间,更有利于蒸排骨预制菜质地、营养品质的保留。
