A comprehensive risk assessment to evaluate the vulnerability of the nearshore cetaceans to increasing marine traffic is *** this study,the risk to Indo-Pacific humpback dolphins(Sousa chinensis)in the main habitats in China was assessed based on a semiquantitative spatial vulnerability analysis.85%of the(sub)population which overlapped with the lanes of ferries and/or cargo vessels,with exposure scores of 1.23±0.31(calculated based on the proportion of sea routes that overlap the dolphin’s range).A combination of high exposure to the sea routes and sensitivity to marine traffic would render the(sub)populations to be highly vulnerable(EPRE:5.21 and XM:4.47).A low frequency of vessels and an awareness of the ecology assures a low vulnerability(SH:2.43,EZ:2.73).Uncertainty scores were commonly lower for the higher vulnerable populations,and higher for the lower vulnerable populations,suggesting additional field data and more monitoring are *** years of field data have been used to analyze the influences of various types of marine traffic on humpback dolphin *** and non-fishing vessels were significantly different(χ^(2)=65.19,p<0.01).The humpback dolphins were attracted by fishing vessels(83.1%)but avoided non-fishing vessels(95.2%).We recommend a management with seasonal and geographical constraints,to balance economic development and environmental conservation.

The practice of shale oil exploration and development all over the world has shown that reservoir quality is a key factor restricting oil and gas production， the study of ultra-deep (4 500 m) reservoirs in petroliferous basins is a hot spot for oil and gas exploration in the world today. In this paper， taking the Fengcheng Formation (P1f) in Mahu Sag of Junggar Basin as an example， through experiments such as geochemistry， whole rock analysis， FE-SEM， N2 adsorption， and CO2 adsorption， the lithofacies are separated， and the pore structure properties of the various lithofacies are compared. Discuss the primary influencing elements that lead to pore structure differences. The results reveal that the shale of the P1f can be separated into four lithofacies (namely felsic shale， mixed shale， lime shale and dolomitic shale)， according to the mineral composition. The shale pores of P1f develop intergranular pores， intragranular pores， organic pores and micro-fractures. Among them， intergranular pores， intragranular pores and micro-fractures are the most developed， and the pore size is larger， which is a favorable storage space. Different lithofacies have different pore development characteristics. With the change of lithofacies (mixed shale - dolomitic shale - lime shale - felsic shale)， the size of the developed pores changes from small to large， and the pore structure changes from "Mainly microporous" to "mainly macropores". The felsic shale has developed laminae， mainly mesopores and macropores， with the largest pore diameter and the highest content of brittle minerals， which is the dominant lithofacies in the shale oil reservoir of the P1f. TOC， felsic and clay minerals all affect the pore development of shale in the P1f， but the influence of organic matter and inorganic minerals on pore volume varies with pore size. The purpose of this article is to characterize the pore structures and regulators of various lithofacies in lacustrine shale and to provide new ideas for

以超临界CO 2萃取贵州小黄姜所得的姜精油为原料,采用溶剂法脱萜制备水溶性姜精油。运用顶空固相微萃取-气相色谱-质谱联用(headspace-solid phase microextraction-gas chromatography-mass spectrometry,HS-SPME-GC-MS)技术对姜精油挥发性成分进行定性和定量,结合气味活性值分析姜精油中挥发性成分对香气的贡献,确定分离目标脱萜物和保留目标香气物,以这两类物质组分的相对含量为考察指标,通过单因素试验得到最优工艺技术参数:70%(体积分数)丙二醇水溶液、离心转速6000 r/min及离心时间15 min、搅拌温度30℃及搅拌时间60 min、料液比(g∶mL)3∶20。在该工艺参数条件下制备的水溶性姜精油相比于原料姜精油的目标脱萜物相对含量从49.20%降低到36.75%,保留香气物从18.59%增加到25.70%。该研究为水溶性姜精油的制备提供了新的技术可行性,有助于拓展姜精油的市场应用空间和范围,并为天然植物精油脱萜制备水溶性精油提供了新的研究思路方法。

为探究在低浓度乙醇下魔芋葡甘聚糖(konjac glucomannan,KGM)的性能和结构变化,拓宽其在食品领域的应用,以粗制魔芋葡甘聚糖为对象,研究其在低浓度乙醇纯化下的凝胶强度、黏度和结构的变化。结果表明,随着乙醇浓度增加和洗脱时间的延长,凝胶强度和黏度都呈现先上升后降低的趋势;随着洗脱次数的增加,凝胶强度和黏度呈现上升趋势。乙醇浓度33%(体积分数)纯化粗制魔芋葡甘聚糖30 min,洗脱2次后,与未经纯化处理KGM相比,凝胶强度和黏度分别显著提升了28.6%和34.7%。根据结构表征可知,粗制魔芋葡甘聚糖经过低浓度乙醇处理后,分子间氢键作用力增强,相对结晶度增高,局部形成有序的短程结构;同时平均粒径变化幅度不大,大小约为270.4μm;且KGM表面所含杂质减少,呈现规则的层状和褶皱分布。因此,通过调控低浓度乙醇纯化条件,可制得适应不同加工需求的KGM。
