Apparently this phenomenon was discovered by Y. W. Chen when treating an exterior free boundary value problem for minimal surfaces. Later S. Hildebrandt and J. C. C. Nitsche proved existence and optimal regularity of solutions to a partially free boundary value problem where edge creeping occurs...
When the train is running, often produce longitudinal force on the rail, the rail for vertical movement, sometimes even drive the sleeper move together. This kind of vertical movement, called the crawl. Crawling generally occurs in the double track railway line interval, single track railway, und...
These observations indicated that the streamer deformation clearly occurs in three distinct phases, (see Supplementary Movie 1). The first - for- mation stage occurs almost earlier streamer formation eaxspsoeroinm(etnfortms)oans the flow stabilizes, which is typically in seconds and in agreement ...
Creeping corrosion occurs from the exposed Cu surface, Cu surface in the role of sulfur-containing substances will generate a large number of black Cu sulfide, and in the exposed surface of Cu and its surrounding diffusion, buildup. The oxide of Cu is insoluble in water. However, the sulfide...
Translocation of gut bacteria naturally occurs in the mesenteries. In Crohn’s disease, translocation of bacteria from inflamed ileum is increased with over-representation of the bacteria C. innocuum (1). This is associated with immune activation of the mesenteric adipose tissue and increased recruit...
The phenomenon of antibiotic resistance precedes the use of these compounds in a clinical context, which is not surprising, considering that they are ubiquitous in nature. For example, phy- logenetic studies indicate that the -lactamases, the principal ...
The driving module has a new type of arm wheel design, in which the change between wheel running and arm creeping occurs as a dynamical phenomenon, ... H Zhang,Z Gong,S Tan - 《High Technology Letters》 被引量: 18发表: 2001年
A PECULIAR creeping film that is similar to the superfilm of liquid helium II, but which occurs at room temperatures and has a much lower transfer rate, takes place in saturated potassium chloride aqueous solution. In an electrolytic experiment using saturated KCl solution as the salt bridge, ...
For X oil field, located in Iraq's southern east, a casing collapse phenomenon has been exposed in four wells, including well X-1, and the salt creeping may be the main reason because the collapsed casing section is encountered by a salt formation that may be creeping u...
