The in situ spraying method is widely used because of its advantages as a trenchless pipeline repair technology, including fast construction speed and close bonding between the lining layer reinforced concrete pipe. However, current research on high-performance spray materials, bearing capacity pipelines before after repair, failure modes two interfaces insufficient. Through laboratory tests de...

A sensitive flow-injection method with chemiluminescence detection (FI-CL) for the determination of dissolved cobalt in open ocean samples, suitable for shipboard use has been developed. To date, FI methods for dissolved cobalt have been used only in coastal and estuarine waters. Therefore, significant modifications to existing methods were required, including (1) the use of a commercially avai...

Abstract Lithium is of great interest as a tracer metamorphic reactions and related fluid-mineral interactions because its potential to isotopically fractionate during inter- intracrystalline diffusional processes. Study transfer through subduction zones, based on study arc volcanic rocks, can yield insight regarding ocean-to-mantle chemical cycling. We investigated major- trace-element concent...
