作者： lingli zheng Deshi Dong 不详

In this study, a simple, reliable and accurate method for the simultaneous separation and determination of naringin, hesperidin, neohesperidin, baicalin, wogonoside, baicalein, wogonin, emodin and chrysophanol in ‘Da-Chai-Hu-Tang’ was developed by reverse-phase high-performance liquid chromatography (RP-HPLC). The chromatographic separation was performed on an Agilent ZORBAX C18 column (250 mm × 4.6 mm i.d., 5.0 μm), and the mobile phase composed of methanol and water containing 1% (v/v) acetic acid was used to elute the targets in a gradient elution mode. The flow rate and detection wavelength were set at 0.8 ml/min and 280 nm, respectively. All calibration curves of the nine components expressed good linearities (r2≥0.9992) within the tested ranges. The RSD values demonstrated the intra- and inter-day precisions were less than 2.89%, and the recoveries of the investigated compounds were between 96.22% and 105.28%. The proposed method is simple, precise, specific, sensitive, and successfully applied to determine the nine marker compounds in ‘Da-Chai-Hu-Tang’ for quality control.

Waterflooding experiments were conducted in micro-models(microscopic scale)and on plunger cores from low permeability,extra-low permeability and ultra-low permeability reservoirs in the Ordos Basin under different displacement pressures using the NMR techniques to find out pore-scale oil occurrence state,oil production characteristics and residual oil distribution during the process of waterflooding and analyze the effect of pore structure and displacement pressure on waterflooding *** bound water condition,crude oil mainly occurs in medium and large pores in the low-permeability sample,while small pores and medium pores are the main distribution space of crude oil in extra-low permeability and ultra-low permeability *** the waterflooding,crude oil in the medium and large pores of the three types of samples are preferentially *** the decrease of permeability of the samples,the waterflooding front sequentially shows uniform displacement,network displacement and finger displacement,and correspondingly the oil recovery factors decrease *** waterflooding,the residual oil in low-permeability samples is mainly distributed in medium pores,and appears in membranous and angular dispersed phase;but that in the extra-low and ultra-low permeability samples is mainly distributed in small pores,and appears in continuous phase formed by a bypass flow and dispersed *** low-permeability samples have higher and stable oil displacement efficiency,while the oil displacement efficiency of the extra-low permeability and ultra-low permeability samples is lower,but increases to a certain extent with the increase of displacement pressure.

由于RTAs环境条款实体法与程序法有机契合模式消除了缔约方“环境义务”和传统的“贸易义务”之间的差异,增强了环境义务在RTAs层面的法律约束力,RTAs超越MEAs及WTO成为保护环境更有效的国际条约典范。但“冲突条款”并未有效澄清MEAs与RTAs环境条款之间的条约关系,“不减损条款”及“有效执行条款”可能导致主权侵蚀风险,RTAs“环境争端解决条款”效力有待实践检验。我国应秉承可持续发展理念,正确处理MEAs与RTAs之间的条约关系,通过“一带一路”稳步推进FTAs环境条款的“中国版”,加强同发展中国家环境合作,进而构建具有中国特色的RTAs环境条款范式,从而为中国参与国际法治、推进中国式法治现代化提供坚实的理论支持。

反规避措施作为反倾销措施的补充和延伸,从其诞生起就引起了各国的激烈争议。以欧美等国为一方的支持者认为,反倾销与反规避措施均属国民待遇原则的例外,符合GATT和WTO的宗旨及原则;以日本、新加坡等国为另一方的反对者则认为,反规避措施实质上是新贸易保护主义的表现。从反规避措施本身出发,结合国际贸易发展趋势分析,反规避措施只要运用得当,是符合GATT和WTO的宗旨及原则的,具有合法性和必要性。WTO应尽早制定反规避法律制度。

全球碳交易市场的构建已经成为低碳经济时代欧美国家的共识。在碳市场的构成要素中,法律规则是最初的也是最重要的核心要素。目前国际碳交易规则基本上由发达国家发起制定,碳交易的国际游戏规则也主要是发达国家之间、发达国家与发展中国家之间利益博弈的结果。中国碳交易从立法到具体实施,有相当多的成熟经验可以借鉴,也有自己的困难需要克服。

跨境电子商务的数据本地化及隐私保护是当前国际贸易法领域新兴而未决的问题。欧盟法院和美国联邦最高法院裁决的两起数据隐私诉讼案,虽然没有直接创立数据本地化法律制度,但突出了美国和欧盟在数据隐私方面不可调和的不同做法,并排除了有效的跨境数据传输路径,使得数据本地化成为仅存的弹性解决方案。WTO电子商务谈判前景不明,而以CPTPP电子商务规则和USMCA数字贸易规则为代表的新生代区域贸易协定禁止数据本地化,禁止强制公开源代码,大有合围建构全球跨境电子商务规则的样板之势。未来示范性区域电子商务规范应基于数据类型,有效规范跨境数据流动及数据本地化措施,同时界定合法的公共政策例外,这是弥合跨境电子商务规则碎片化的举足轻重的区域法治现代化变革。
