The invention discloses a quick spawning method of Atrina pectinata seed shells. The quick spawning method includes following steps: selecting Atrina pectinata seed shells, performing indoor artificial feeding, and rising temperature step by step to promote maturity breeding to enable sexual glands of the Atrina pectinata seed shells to be mature for waiting for delivery; performing low-temperature drying and exposure on the Atrina pectinata seed shells with mature sexual glands; adding filtered seawater into a container where the Atrina pectinata seed shells are placed, continuously inflating, and performing low-temperature water breeding; transferring the Atrina pectinata seed shells into a spawning pool for ovulation and spermiation. Low-temperature drying and exposure and low-temperature water breeding of a period of time are performed on the seed shells waiting for delivery, and then the seed shells are placed in the spawning pool high in temperature. Due to double stimulation of cooling and heating, spawning rate reaches higher than 60%. By using the quick spawning method, the problem that indoor artificial breeding of Atrina pectinata is difficult in parent shell spawning and low in seed shell spawning rate is solved, needs on a large amount of high-quality eggs for artificial breeding of Atrina pectinata are met, and a foundation is provided for artificial large-scale breeding of Atrina pectinata.

The invention discloses an artificial electronic cochlea, a speech processor and a method for processing a speech with double stimulation rates. The speed processor and the method are applied to the artificial electronic cochlea, and the method comprises the following steps of: firstly, performing preprocessing, band-pass filtering, half-wave rectification and low-pass filtering on speech signalsto acquire the envelope amplitude of each channel, and adjusting the current amplitude to a working amplitude range; secondly, selecting a plurality of channels of which the envelope amplitudes are more than or equal to a threshold value to form a first part (high-amplitude) channel, and performing pulse sequence modulation with a first (high) stimulation rate on the first part channel; selectinga plurality of channels of which the envelop amplitudes are smaller than the threshold value to form a second part (low-amplitude) channel, and performing pulse sequence modulation with a second (low) stimulation rate on the second part channel; and adopting electronic pulse sequences of the first and second part channels after modulation to stimulate corresponding stimulating electrodes. The artificial electronic cochlea, the speech processor and the method realize the aim of transmitting information on the envelope amplitudes of all the channels to an artificial electronic cochlea patient, and effectively improve the speech recognition effect of the artificial electronic cochlea.

The invention discloses a preparation method of a double-stimulation expanding gel particle for preventing gas channeling in the process of carbon dioxide oil displacement. The method includes: 1), dissolving an acrylamide monomer into water to form a solution, adding a crosslinking agent, a temperature response monomer methacrylic acid N, an N-dimethylaminoethyl ester monomer and carbon dioxide response monomer (2-(methacrylenyl oxide) ethyl) dimethyl-(3-sulfonic acid propyl) ammonium hydroxide to the solution with even stirring to form a mixed monomer solution polymerization system, and feeding nitrogen to the polymerization system to remove dissolved oxygen in the system; 2), mixing the mixed monomer with an initiator solution for polymerization reaction. The gel particle continuous expands under CO2 and thermal stimulation, secondary expansion of the gel particle under the acidic environment is achieved, and long-time blocking function can be played.
