This invention discloses a reactor for water-gas shift reaction and its application. The reactor is suitable for water-gas shift reaction processes containing gaseous and liquid reactants. A reaction chamber is set inside a hollow, sealed cylinder formed by the reactor walls. The reaction chamber is a hollow, sealed chamber surrounded by porous material as its wall surface. A gaseous reactant inlet pipe penetrates the reactor wall and extends into the upper part of the reaction chamber, a liquid reactant inlet pipe penetrates the reactor wall and extends into the cylinder, and a reaction product outlet pipe penetrates the reactor wall and extends into the lower part of the reaction chamber. The catalyst for the water-gas shift reaction is packed in the reaction chamber. The water-gas shift reaction can be carried out under near-isothermal conditions. Water in the liquid reactant does not need to be pre-vaporized and is directly fed into the reactor in liquid form, saving the energy consumption required to transport the corresponding amount of water vapor. Simultaneously, a high molar ratio of water to carbon monoxide is maintained within the reactor, promoting complete conversion of carbon monoxide.

The invention relates to the field of electronic technology, and discloses a bitstream testing method, a device, a computer device, a storage medium and a program product. The bitstream testing method generates an excitation signal corresponding to the input variable by reading parameter information of the input variable in a test case table; parses a wiring file to obtain pin information of each input variable and a corresponding output variable; generates a simulation excitation file based on a reference model, the pin information of each input variable, the excitation signal and the pin information of the corresponding output variable, thereby ensuring the accuracy of the simulation excitation file, reducing the possibility of manual operation errors, effectively improving the efficiency of the bitstream test, making the test result more reliable, and ensuring that the generated excitation signal meets the test requirements and specifications.

The invention belongs to the technical field of electronic technologies, and particularly relates to a dynamic route generation method and device, equipment and a medium. The method comprises the steps of obtaining login information input by a user; the login information is sent to a server; acquiring an authority file determined by the server according to the login information; and generating an interaction menu and a dynamic routing instance matched with the interaction menu according to the permission file. The problem that maintenance is not easy due to the fact that permission setting is complex in the prior art is solved, and the management efficiency and the secondary development efficiency of developers are greatly improved. And meanwhile, the problem of slow page loading caused by overlarge storage capacity of a single routing configuration file is also avoided. And the front end is only provided with the routing list corresponding to the authority, so that the user cannot enter a non-authority page in a manner of directly inputting the website, and the safety of the system is improved.

The invention discloses a smart city networking monitoring type garbage can operation state evaluation method, and relates to the technical field of garbage can monitoring, and the method comprises the following steps: collecting equipment information and system information during operation of a networking monitoring type garbage can; performing comprehensive analysis on the equipment information and the system information, establishing a data analysis model, and generating an operation state evaluation index; and the operation state evaluation indexes are compared with the operation state evaluation indexes, and the operation state of the networking monitoring type dustbin is evaluated. The operation state of the networked monitoring type dustbin is obtained through the operation state evaluation index, when the operation state of the networked monitoring type dustbin becomes poor, a maintainer is prompted to maintain the networked monitoring type dustbin in advance, the timeliness of maintenance of the networked monitoring type dustbin is improved, and the maintenance efficiency of the networked monitoring type dustbin is improved. And the situation that the maintenance difficulty is increased and the maintenance time is prolonged due to the fact that the networking monitoring type garbage can breaks down is effectively prevented, and efficient use of the networking monitoring type garbage can is facilitated.
