Abstract: A fault processing method includes: a fault processing apparatus receives first hardware fault information generated by a first PCIe device on a first PCIe link. The first hardware fault information includes a device identifier of the first PCIe device and is used to indicate that a hardware fault occurs on the first PCIe device. Further, the fault processing apparatus performs, based on the first hardware fault information, fault recovery on the first PCIe link on which the first PCIe device is located, and interrupts a software service related to the first PCIe device.

Abstract: A power conversion system, an energy storage system and a power supply method are provided. The power conversion system includes a battery management system and an auxiliary power supply. A positive electrode of the auxiliary power supply is connected to a positive electrode of a battery rack. The auxiliary power supply is configured to obtain power from the battery rack, convert the power obtained from the battery rack, and supply the converted power to the battery management system and a load in the power conversion system. The battery management system is configured to sample a voltage of the battery rack and a current of the battery rack, and control charging and discharging of the battery rack based on the voltage and the current.

Abstract: Disclosed herein is a novel monohydrate polymorphic form of S-nitrosocaptopril (CapNO), process for preparation, pharmaceutical compositions and method of treating pulmonary hypertension, hypertension, or congestive heart failure thereof. A process for the preparation of S-nitrosocaptopril crystalline form is provided which comprises the following steps: reacting captopril, sodium nitrite and EDTA-2Na.2H2O in 15±5 wt % saline, adjusting pH to precipitate the crystal, and recrystallizing S-nitrosocaptopril monohydrate crystalline. The crystals can be stably stored at 4° C. for at least 12 months.
