Abstract: The present disclosure provides a system and method for verifying alternating current (AC)/direct current (DC) conversion of an ultralow-frequency voltage. The system includes a quantum voltage generation system, a low-frequency signal source, a follower, three switches, a double-heater-strip thermoelectric converter, a nanovoltmeter, a clock source, a high-precision digital sampling system, and an upper computer. Based on DC and AC quantum voltage technologies and with reference to the double-heater-strip thermoelectric converter, an ultralow-frequency voltage is traced to a DC quantum voltage through AC/DC conversion, and a conversion result is compared with an AC quantum voltage to verify rationality of precision and an uncertainty evaluation result of AC/DC conversion of the ultralow-frequency voltage, so as to ensure reliability of AC/DC conversion of the ultralow-frequency voltage. This resolves a problem that the AC/DC conversion result of the ultralow-frequency voltage cannot be verified.

Abstract: The invention discloses a charging state analysis method of a electric vehicle based on electrical characteristic sequence analysis. The method includes following steps: step S1, obtaining voltage sampling data and current sampling data of the electric vehicle during charging; step S2, setting a time interval, so as to divide the voltage sample data and the current sampling data obtained in step S1 into multiple data sets; step S3, calculating an electrical characteristic vector of each time interval; step S4. adding the calculation results of Step S3 to a temperature sensing value T, and generate an electrical characteristic sequence of whole charging cycle; step S5, inputting the electrical characteristic sequence of the electric vehicle into a trained Time Recurrent Neural Network (TRNN) in sequence to obtain corresponding results; if the result is 1, it means normal; if the result is 0, it means abnormal.

Abstract: The present invention relates to a fault-tolerant modular permanent magnet assisted synchronous reluctance motor (PMaSynRM) and provides a modular winding connection method. The modular winding connection is to change the positions of inlet and outlet coils based on the slot electrical potential star vectogram. Then, each module has a separate set of winding and the left and right relative distribution will be adopted on the winding connection. The invention has the advantages of modularization in structure, high independence between the modules, effectively avoiding overlapping of magnetic lines between the modules, and improving fault tolerance and reliability of the motor. The invention has the advantages of modularization in structure, high independence between the modules, magnetic decoupling between the modules, and improvement of fault tolerance and reliability of the motor.

Abstract: A valve for switching waterways and adjusting flow has a fixed seat, a control piece and an operation mechanism. The fixed seat is provided with a fixed face, an inlet waterway and two outlet waterways, the inlet port of the inlet waterway and the outlet ports of the outlet waterway are arranged on the fixed face. The control piece is provided with a control face that is relied on the fixed face hermetically and a communicating groove that is concavely arranged on the control face. The operation mechanism is connected with the fixed seat and the control piece, and can drive the control piece to move, and then the control face can be driven to rotate and slide relative to the fixed face.

Abstract: The present invention relates to the isolation, purification, sequencing, and functional characterization of the class I diterpene synthase sequence OsKSL11. Transcriptional control of OsKSL11 provides a means of regulating production of stemodene. Further, since OsKSL11 is highly homologous to OsKSL8, identification of the sequence of OsKSL11 will facilitate identification of underlying enzymatic determinants that affect product outcomes with these enzymes.

Abstract: The present invention relates to the isolation, purification, sequencing, and functional characterization of the class I and II terpene sequences OsCPS1ent, OsCPS2ent, OsCPS4syn, and OsDTS2. Transcriptional control of OsCPS1ent provides a means of regulating production of gibberellin phytohormone, while transcriptional control of OsCPS2ent, OsDTS2, and OsCPS4syn provides a means of regulating defensive phytochemical biosynthesis. Further, these enzymatic genes offers a means by which terpenoid production may be more generally modulated, specifically including genetic engineering, as well as ex vivo uses.
