Orogenic peridotites in the crystalline basement of the northwestern Bohemian Massif contain multiphase solid inclusions (MSI), which are interpreted to be crystallisation products of trapped former carbonate–silicate melts metasomatizing their host rocks. We applied conventional thermobarometry and forward ...
The grain boundary internal friction peak (GBP) of Al Mg polycrystals has been measured in an inverted torsion pendulum. The height of the GBP is greatly suppressed GBP recovers after annealing at an Al-2.4wt.%Mg and Al-6.0wt.%Mg specimens. This suppressed GBP recovers after annealing at an...

Water activity also controls the barium partitioning with a marked decrease in D Ba af/liq for addition of less than 0.8 wt% H 2 O, but with no apparent additional effect for higher water contents in the bulk composition (e.g., from 0.8–4.2 wt% H 2 O). The composition of alkali ...
The present invention relates to an average particle size of less than 0.5μm comprising Solution agglomerated barium sulfate epoxy resin, and is characterized by improved impact strength and flexural elongation at break. 本发明的环氧树脂适于在船舶制造,风力涡轮机,管道,容器或飞行器构件中用作复合材料...
The barium was supplied episodically to shallow oceans through the upwelling of deep Ba2+-rich water. This conclusion is echoed by the sequence of events occurring at the aftermath of Marinoan meltdown in the entire South China Block2. In many shallow platform, shelf, and basinal facies of...
Observation of bright spatial photorefractive solitons in a planar strontium barium niobate waveguide We have obtained stationary bright spatial solitons in a planar photorefractive strontium barium niobate waveguide for visible light ranging from 514.5 to ...

The response of a strong bainitic-steel to tempering at high temperatures is investigated, because a softened state is sometimes necessary during the manufacture of engineering components, prior to the final heat-treatment which hardens the material. The
