Method for breeding double white shell Japanese scallop

Method for breeding double white shell Japanese scallop

The invention discloses a double white shells patinopecten yessoensis cultivation method. The patinopecten yessoensis individual, in which the upper shell whitening region area is more than 30% and the gonad development is plump, is firstly selected as a parent scallop. In the particular conditions such as density, temperature and so on, the accelerated ripening, the induced spawning, the artificial insemination, the hatching, the cultivation, the attachment seedling collection, the ex-storage, the intermediate seedling protection and growth, as well as the mariculture are implemented, so that the patinopecten yessoensis in which the whitening area is increased further is cultivated. Moreover the patinopecten yessoensis obtained is taken as a parent scallop to repeat the above steps. The steps are repeated for several times until a scallop seedling in which the upper and lower shells colours are entire pure white is obtained. The double white shells patinopecten yessoensis not only has ...

Power line communication method and related equipment

The embodiment of the invention discloses a power line communication method and related equipment. The method comprises the following steps: acquiring information to be sent and a target power line; generating characteristic current based on the to-be-sent information and a Manchester encoding mode, and injecting the characteristic current into the target power line; acquiring a load current of a target power line carrying the characteristic current to obtain a current signal; and calculating an energy signal of the current signal to obtain a data frame corresponding to the to-be-sent information so as to complete a power line communication process. The mode of injecting the non-same-frequency modulation current into the power line is adopted, so that the communication process of the power line is not limited by the state of a circuit breaker, and the influence of same-frequency interference and large-current load is avoided. No matter what state the circuit breaker is in, effective communication ...
