The invention relate to a method applicable to pipeline, in particular to a method of repairing reinforcing and / or strengthening a metallic pipe and a pipe crack arrest method, which is characterized in that: a part of a pipe needing repairing reinforcing and / or strengthening or needing crack arrest is firstly coated with insulating material, and then high strength fiber composite material is applied. As the materials used in the invention and the material used in the metallic pipe body portion a similar elastic modulus, the materials used in the invention can be integrated with the pipe body to bear pressure in the pipe together and finally form a bearing capacity required by the composite pipe, such as the original maximum working pressure of the pipe restored; furthermore, the materials used in the invention have good crack arrest function in case of a pipe burst accident. In addition, the insulating material used in the bottom layer completely removes the possibility of galvanic corrosion between the pipe and the reinforcing material. The method provided by the invention which has simple construction without fire work not only facilitates the close attaching between the reinforcing material and the pipe body and between reinforcing layers, but also enables repairing reinforcing and strengthening operations on pipelines in active service.

A remote control device remotely controls a communication terminal including a first communication portion performing radio communication by a first communication system and a second communication portion performing radio communication by a second communication system. The remote control device includes a determination portion and a terminal power supply control portion. The determination portion determines whether or not to allow radio communication by the communication terminal via the second communication portion. The terminal power supply control portion controls the communication terminal in order to establish a state that the second communication portion of the communication terminal consumes less power when the determination portion determines not to allow radio communication via the second communication portion.

Embodiments of the invention provide an uplink non-orthogonal scheduling-free method and device. The method comprises the following steps that a base station groups multiple access resources and configures to obtain at least two groups of multiple-access resource pools, wherein at least some multiple access resources in the at least two groups of multiple access resource pools are different; and the base station informs the at least two groups of the multiple access resource pools obtained by configuration to the terminal, and the terminal selects a used multiple access resource pool from theat least two groups of multiple access resource pools. Through adoption of multiple access resource grouping and multiplexing, the interference of adjacent cells is reduced, so that the available multiple access resources cannot be reduced, and a large amount of signaling loads cannot be generated.

The invention provides a cobaltosic oxide quantum dot and a preparation method thereof. The preparation method includes: using short-chain alcohol as surfactant to wrap hexahydrate cobalt nitrate so as to form settled solution A, using long-chain alcohol as solvent to be well mixed with settled solution A so as to form cobalt nitrate reverse micelle solution, subjecting cobalt nitrate reverse micelle solution to microwave reaction to promote hydrolysis and purification of cobalt nitrate, and separating materials after microwave reaction to obtain the cobaltosic oxide quantum dot. The cobaltosic oxide quantum dot prepared by the method is 3-4 nanometers in particle size, has evident quantum confinement effect, can be well dispersed in water to form colloid, and is capable of generating hydrogen and oxygen by resolving pure water according to standard mole ratio 2:1 under visible light without load and mixing. The cobaltosic oxide quantum dot is also applicable to fields of fluorescopy, electrocatalysis, chemical catalysis, super capacitors and novel batteries.

Introducing a sorption filter with at least one layer of activated carbon granules, the purpose of which is to improve a sorption filter of the type mentioned at the outset in such a way that it has an The breakdown characteristics are much better than that of the device, which is characterized by: at least 20% by weight of the activated carbon particles have a particle size smaller than 0.180mm, and the total area weight of the activated carbon is between 100 and 500g / m2. The adsorption filter of the invention is characterized by a high immediate adsorption efficiency.
