The invention discloses a data transmission method and device, and the method and device are used for solving a problem that the system spectrum utilization rate of a conventional distribution algorithm based on time slot reservation is low because the conventional distribution algorithm employs a mode of time division multiplexing. The method comprises the steps that a first node selects a first time frequency resource occupied by the first node from time frequency resources, corresponding to a condition that the first node is a spare sub-band, from a time slot which can achieve frequency division multiplexing, and carries out the data transmission on the first time frequency resource, wherein at least one time frequency resource, except the time frequency resource occupied by the first node, on the time slot which can achieve frequency division multiplexing serves as a second time frequency resource occupied by the second node, and the spatial isolation degree between the first node and the second node is less than the minimum spatial isolation degree that the nodes capable of reusing the same time frequency resource need to meet, and is greater than the maximum distance that nodes with the communication demands need to meet, thereby achieving the frequency division multiplexing of the time slot between at least two nodes without communication demands.

The optical fiber and optical electronic device vertical coupling method is particularly applicable to optical fiber coupling output of optical electronic devices like single-photo sources which are small in light area and in need of spatial isolation, and has the advantages of being high in spatial resolution ratio and simple and reliable in technology.

The invention provides a nonpolar solar cell utilizing a spontaneous polarization electric field. The nonpolar solar cell sequentially comprises a substrate, a GaN nucleating layer, a non-doped GaN buffer layer, an n-type GaN layer, an InGaN absorption layer and a p-type GaN layer from bottom to top, wherein all nitride epitaxial layers except the substrate are made of a nonpolar material, a p-type ohmic electrode is led out on the p-type GaN layer, and an n-type ohmic electrode is led out on the n-type GaN layer. As the single-direction spontaneous polarization electric field parallel with the epitaxial layer exists in the nonpolar epitaxial layer, and the p-type ohmic electrode and the n-type ohmic electrode are respectively located at the positive end and the negative end of the spontaneous polarization electric field, the existence of the spontaneous polarization electric field is favorable for improving the horizontal (namely the direction parallel with the surface of the cell) spatial isolation efficiency of a photon-generated carrier electron hole pair in the solar cell, the spontaneous polarization electric field further speeds up the transmission of the separated hole and electron to the positive electrode and the negative electrode, so that the production efficiency of an photoelectric current is greatly improved.

The present invention relates to methods for correction of psychological conditions in individuals, as well as to passenger ships for carrying out such methods and may be used in psychological practice and in the fields of medicine and shipbuilding. The technical effect attained by the floating centre according to the present invention is restoration of mental equilibrium, self-reliance, improvement of social adaptation and reaching feelings of self-affirmation. According to the invention, an individual is placed in a spatially isolated passenger cabin at a floating centre for continuous stay during an individually chosen number of days ensuring his / her visual and spatial isolation. Under these conditions an individual is subject to strict daily regime and tests. His / her diet is modified and controlled. At the same time, an environment for physiological improvement and intellectual development is created. A psycho-physiological condition of an individual is monitored remotely with the use of physiological sensors and locally by visual inspection, and the conditions are gradually changed thus increasing the degree of individual's acclimation. The structure of the ship serves its purpose. The hull and erection are made as a single structure having the closed space isolated from the boards by longitudinal partitions, this space being divided into four isolated zones where the rows of cabins are situated. Above the overall top surface of the closed space, a glass-enclosed promenade deck is situated. Cabins are situated in each isolated zone on truncated decks. Between the cabins there is a corridor having the height equal to the sum of heights of all truncated decks with the cabins.
