摘要： An offshore rocket transport and launch method includes S1: assembling a rocket horizontally; S2: loading the assembled rocket as a whole into a transport cage; S3: transporting, by a transport vehicle, the transport cage loaded with the rocket to a wharf by land horizontal transport; S4: transferring the transport cage loaded with the rocket to a transport ship, and transporting the transport cage loaded with the rocket to an offshore rocket launch pad by sea transport; S5: hoisting, by a hoisting device, the transport cage loaded with the rocket to the rocket launch pad; S6: opening the transport cage, transferring the rocket to a launching position, and hoisting the transport cage away from the rocket launch pad; and S7: launching the rocket. The method effectively facilitates the offshore rocket transport and launch process, and prevents the rocket from being affected by the external environment during the launch process.

摘要： A method for identifying an individual of an oplegnathus punctatus based on a convolutional neural network is provided. Target initial positioning involves three continuous convolutional layers and an average pooling layer. A region of feature interest point is obtained, a hyperparameter candidate box is set to obtain a region, thereby obtaining an approximate position of a target object. II_Net backbone convolutional neural network includes six convolutional layers and four pooling layers, which includes a LeakyReLU activation function used as an activation function of the first convolutional layer, convolutional network layers of Alexnet and parameter data, and a maximum pooling layer of an overlapped pooling structure. Fully connected layers use a genetic algorithm to improve data transmission between layers. With the established model, identification of the individual of the oplegnathus punctatus is performed by using test data.

摘要： A barrage with a function of collecting floating garbage on a water surface is provided. It includes a first dam body as a main body of the barrage provided with multiple built-in low water level drainage channels and high water level drainage channels, a second dam body provided with multiple notches for converging floating garbage on the water surface, a garbage collecting and storing equipment arranged between the first dam body and the second dam body and a solar power generating equipment. The garbage collecting and storing equipment maintains running of the garbage conveyor belt by utilizing electric energy provided by the solar power generating equipment, thereby collecting garbage in a garbage pool beside the barrage. It not only has conventional functions of the barrage, but also greatly saves cost of manually salvaging garbage and avoids water pollution caused by accumulation of garbage on the river surface.
