Abstract:
A method, an apparatus, and a system for online migrating from a physical machine to a virtual machine are provided. The method including: after a target virtual machine is created, started, and suspended by a virtualization platform VMM Host, initially synchronizing data of a memory page from a source physical machine to the target virtual machine at a second time point; monitoring the operation of updating the memory page since the second time point; incrementally synchronizing data of the updated memory page in the source physical machine to the target virtual machine, and stopping monitoring when an increment value of the updated memory page in the source physical machine is less than a first threshold; and calling the virtualization platform VMM Host to resume the target virtual machine to a running state. The effect of smoothly switching services from the source physical machine to the target virtual machine is achieved.
Abstract:
The present invention relates to valve metal particles uniformly containing nitrogen and a method for preparing the same, and a valve metal green pellet and a sintered pellet made from the particles, and an electrolytic capacitor anode. The present invention provides valve metal particles uniformly containing nitrogen, wherein the difference ratio of nitrogen contents of particles is 20% or less. The present invention provides a process for preparing said valve metal particles uniformly containing nitrogen, wherein the raw material particles of the valve metal were heated in a nitrogen-containing gas at a temperature of 200° C. or less for 2 hours or more. The present invention also provides a valve metal green pellet made from said valve metal particles. The present invention also provides a valve metal sintered pellet.
Abstract:
A method for synthesizing nature-identical raspberry ketone is provided, belonging to the technical field of pharmaceutical synthesis. The nature-identical raspberry ketone is obtained by using natural p-anisaldehyde and natural acetone as initial raw materials to allow three-step continuous reactions of basic resin-catalyzed Claisen-Schmidt condensation, enzyme-catalyzed reduction, and demethylation of sodium ethanethiolate. The synthesis method is safe and clean, and has a stable yield reaching approximately 85%, providing a basis for industrial continuous production. The synthesis method not only meets the requirements for clean production, but also saves labor costs by virtue of the continuous process, and is suitable for large-scale industrial production.
Abstract:
A production method for producing an oxygen sensor, includes spinning a precursor consisting of a salt of at least one metal chosen from Sc, Y, La, Ce, Pr, Nd, Sm, Gd, Dy, Ho, Yb, Sr, Ba, Mn, Co, Mg, and Ga, a solvent, and a macromolecular polymer to produce nanofibers of the precursor containing the salt of the metal. The method further includes calcining the nanofibers of the precursor at a temperature ranging from 550° C. to 650° C. for 2 to 4 hours, and making a solid electrolyte material composed of the nanofibers obtained from the calcining. The resulting solid electrolyte material constitutes a part of the oxygen sensor.

Abstract:
The invention related to the recycling field of waste printed circuit boards (WPCB), and especially involved a complete non-cyanogens wet process for green recycling of WPCB, which belonged to the field of recycle economy. In the invention, the process included that WPCB were broken by the jaw crusher, and then mixed copper powders and nonmetallic powders were separated by the method of air classification, the mixed copper powders were smelted and casted to get copper anode plates, the copper was purified by electrolytion, the valuable metals (such as copper, gold, silver, platinum and palladium, lead and tin) were recycled from the copper anode slime, and the waste water was recycled. The recovery ratio of all-metal was above 98%. The purity of the cathode copper was up to 4N level. The ratio of de-coppering was above 96%. The recovery ratio of gold was above 98.
Abstract:
Disclosed are an alignment film printing method of LCD panel and device thereof. The method comprises: acquiring position information of one or more defect substrate units of a substrate; delivering the position information to a process management system; delivering the position information to a first alignment film printing apparatus by the process management system; and excluding the alignment film printing operation to the defect substrate units performed by the first alignment film printing apparatus. The benefits of the present invention is to control the back-end processes for excluding steps of the printing operations, the detection and etc to the defect substrate units, accordingly, material cost of alignment film printing can be saved.
Abstract:
