Abstract: A diesel engine includes a cylinder head, a cylinder sleeve, a piston, an injector, and a combustion chamber. The top side of the piston includes an annular top surface, an annular collision belt and an annular cavity. The collision belt includes a collision surface, an upper guide surface, and a lower guide surface. An annular throat is formed between the upper guide surface and the cylinder head. The collision belt divides the combustion chamber into a headspace and a central portion. The volume of the headspace is more than three times of the volume of the central portion. A major portion of the fuel jet injected by the injector is directed into the headspace. The results are faster mixing of fuel and air and complete combustion in the combustion chamber, and a reduction of fuel consumption rate by 2%. A method for fuel distribution and combustion is also disclosed.

Abstract: The invention, belonging to the field of membrane technology, presents a method for the direct growth of ultrathin porous graphene separation membranes. Etching agent, organic solvent and polymer are coated on metal foil, and then they are calcined at high temperature in absence of oxygen; after removal of metal substrate and reaction products, single-layered or multi-layered porous graphene membranes are obtained. Alternatively, the dispersion or solution of etching agent is coated on metal foil, on which a polymer film is then overlaid. The obtained sample is subsequently calcined at high temperature in absence of oxygen; after removal of metal substrate and reaction products, single-layered or multi-layered porous graphene membranes are obtained. The method involved in this invention is simple and highly efficient, and allows direct growth of ultrathin porous graphene separation membranes, without needing expensive apparatuses, chemicals and graphene raw material. Additionally, the graphene membranes prepared with this method have controlled pore size, ultrahigh water flux and strong resistance to irreversible fouling.

Abstract: The invention provides a device and method for measuring the temperature of end face turning, which belong to the technical field of cutting and are applicable for measuring the temperature of cutting area during end surface turning. The device comprises a thermocouple sensor, a slip ring and a specially designed experiment workpiece. The circular ribs designed on the experiment workpiece transform the end surface turning into cylindrical turning. The design of a through hole and a blind hole makes the thermocouple sensor reasonably buried in the workpiece, which improves the safety of the turning process and the stability of signals. At the same time, the interference between devices is eliminated by using the slip ring structure. A temperature signal is collected by a data collection card via the slip ring and transmitted to a computer, and finally, a relatively accurate end surface turning temperature is obtained. The present invention has simple structure and easy operation, and provides a good device and method for realizing accurate measurement of end surface turning temperature.

Abstract: The present invention belongs to the technical field of health monitoring for civil structures, and an anomaly identification method considering spatial-temporal correlation is proposed for structural monitoring data. First, define current and past observation vectors for the monitoring data and pre-whiten them; second, establish a statistical correlation model for the pre-whitened current and past observation vectors to simultaneously consider the spatial-temporal correlation in the monitoring data; then, divide the model into two parts, i.e., the system-related and system-unrelated parts, and define two corresponding statistics; finally, determine the corresponding control limits of the statistics, and it can be decided that there is anomaly in the monitoring data when each of the statistics exceeds its corresponding control limit.

Abstract: The disclosure relates to a method for fermentation integrated with separation and purification of acetone, butanol, and ethanol (ABE) or butanol alone, comprising the following steps: 1) obtaining ABE by fermentation using an acetone-butanol-producing bacterium or obtaining butanol using a butanol-producing bacterium; 2) using a “vapor-stripping-vapor-permeation” method (briefly VSVP) for online separation and purification of ABE or purifying butanol from the fermentation broth; wherein the VSVP method comprises the following steps: introducing a gas bubble into the fermentation broth comprising active cells for fermentation to vaporize ABE or Butanol; subjecting the gas along with the vaporized ABE or Butanol to a membrane separation unit to pass through the membrane; recovering ABE or Butanol, or subjecting ABE or Butanol to a next separation device. By using the disclosed method, production, separation, and purification efficiency of ABE or butanol are improved with saved energy consumption and without increasing equipment investment.
