土工试验中的几个问题探讨

通过多组宁波和温州软土不同剪切速率的直剪固结快剪、不同预压时间下软土直剪固结快剪和三轴固结快剪试验中多样剪和多级剪的试验研究,表明①剪切速率对软土的抗剪强度影响较大,现有国家标准确定的0.8 mm/min剪切速率对软土并不合适;②预压时间超过6 h后软土强度增加不大;③对多样剪和多级剪而言,高灵敏度的软粘土两者差别较大,而对低灵敏度软粘土在掌握一定试验方法和试验技巧下,可用多级剪代替。这些结论对生产实践是有用的。     

英汉视译理解策略与英语快速阅读技巧的认知相关性

英汉视译理解策略（顺句驱动、类意群断句）与英语快速阅读技巧（扫描、跳读）均服务于文本的快速理解,从认知心理层面讲,都是用于高效激活认知主体已有的非言语心理空间或动态整合已有的非言语心理空间而创生新的非言语心理空间。文本由线性句子构成,句子结构的心理实质是非言语心理空间在语言层面的在线空间部署模式。言语理解时,加工句子的过程是“线性、立体”的过程,其效率取决于结构清晰度和回视率。

Enabling Mg metal anodes rechargeable in conventional electrolytes by fast ionic transport interphase

Rechargeable magnesium batteries have received extensive attention as the Mg anodes possess twice the volumetric capacity of their lithium counterparts and are dendrite-free. However, Mg anodes suffer from surface passivation film in most glyme-based conventional electrolytes, leading to irreversible plating/stripping behavior of Mg. Here we report a facile and safe method to obtain a modified Mg metal anode with a Sn-based artificial layer via ion-exchange and alloying reactions. In the artificial coating layer, Mg₂Sn alloy composites offer a channel for fast ion transport and insulating MgCl₂/SnCl₂ bestows the necessary potential gradient to prevent deposition on the surface. Significant improved ion conductivity of the solid electrolyte interfaces and decreased overpotential of Mg symmetric cells in Mg(TFSI)₂/DME electrolyte are obtained. The coated Mg anodes can sustain a stable plating/stripping process over 4000 cycles at a high current density of 6 mA cm⁻². This finding provides an avenue to facilitate fast ion diffusion kinetics of Mg metal anodes in conventional electrolytes.

Copper(II) hydroxide on artefacts: Corrosion,conservation, colourants

Copper(II) hydroxide (as the rarely occurring mineral spertiniite) is formed under alkaline, oxidising conditions. It has been observed as a naturally occurring corrosion product of brass in sea water. But most occurrences on copper alloys are due to conservation treatments using basic solutions (sodium hydroxide or ammonia) or to intentional patination. Classical brass centrepieces (c. 1800), ‘cleaned’ with ammonia solution, developed a blue spertiniite patina in gaps, where evaporation was hindered. Additional to the danger of stress corrosion cracking this is another reason now outlawing this treatment. Copper pigment layers will transform to copper hydroxide when exposed to bases. The treatment of basic copper salts with bases has been used intentionally in the production of Bremen blue and similar pigments which can be composed of copper hydroxide as well.
