This invention discloses a liquid temperature-controlled system for phage preparations, belonging to the field of biological agent storage and transportation. The liquid temperature-controlled system for phage preparations includes a housing, a temperature regulation unit, an energy storage and power supply unit, a solar power generation unit, an environmental sensing unit, an intelligent control unit, and a monitoring, control, and data acquisition unit. This invention solves the problems of existing temperature-controlled storage equipment relying on mains power, insufficient energy management efficiency, and susceptibility to failure due to energy depletion in outdoor or unstable power environments. Through solar self-powering and intelligent energy prediction management, this invention enables long-term self-sustaining operation of the system in complex environments. Furthermore, by employing a multi-mode switching and adaptive temperature control strategy based on energy prediction, it can improve the system's environmental adaptability and energy utilization efficiency while ensuring the core temperature requirement for phage preparation activity.

The application discloses a sandbox-based file security isolation method and device, equipment and medium, and relates to the field of sandbox, and comprises the following steps: determining the operation type of the current operation; if it is a write operation, determining a first file encryption key, encrypting a first target file by using the first file encryption key to obtain a first encrypted file, storing the first encrypted file and the first file encryption key in the encryption space of the sandbox through the encryption path of the sandbox, and encrypting the first file encryption key by using the key encryption key built in the sandbox to obtain a first encrypted key; if it is a read operation, reading a second file encryption key and a second encrypted file from the encryption space through the encryption path, decrypting the second encrypted file by using the second file encryption key to obtain a second target file; and the second file encryption key is a key obtained by decrypting the second encrypted key in the encryption space by using the key encryption key. The file security in the sandbox environment can be improved.

This utility model relates to a fire-resistant storage device for oily waste bleaching clay, comprising a storage tank connected to the discharge pipe of at least one filter, a spraying assembly for spraying atomized water onto the oily waste bleaching clay inside the storage tank, an inflation assembly for filling the storage tank with inert gas, a detection assembly for detecting the storage environment inside the storage tank, and a controller for controlling the spraying of atomized water and the filling of inert gas. This utility model uses the detection assembly to detect the temperature, smoke, and oxygen content inside the storage tank containing the oily waste bleaching clay. Based on the detection results, nitrogen is injected into the storage tank using the inflation assembly to reduce the oxygen content. The spraying assembly sprays atomized water onto the oily waste bleaching clay inside the storage tank. These two methods work together to reduce water consumption and also reduce the risk of spontaneous combustion of the oily waste bleaching clay, thus improving storage safety.
