The invention provides a suppression method for stimulated Brillouin scattering of an optical fiber laser amplifier system. The optical fiber laser amplifier system includes a seed source and an optical fiber amplifier; and inclined optical fiber grating is accessed into the optical fiber amplifier, and filtering is performed on a laser input in the inclined optical fiber grating by utilizing thehigh loss of the inclined optical fiber grating in a Brillouin wave band to suppress the stimulated Brillouin scattering. The inclined optical fiber grating has the high loss in Brillouin wave band and has better suppression effects on backward Stokes signal light generated by the optical fiber laser amplifier system, and so, an overall SBS threshold of the optical fiber laser amplifier system canbe improved, the risk of high power backward light on the optical fiber laser amplifier system is greatly reduced, and the performance of the optical fiber laser amplifier system is improved.

The invention provides a terminal device and a shell applied to the terminal device. The terminal device comprises a first body and a second body. The first body comprises a first display unit. The second body is arranged on the back face of the first body and can slide towards at least one edge of the first body along the back face of the first body. The second body comprises a connection part and a supporting part. By means of the connection part, the second body is connected with the first body in a slidable mode. The supporting part comprises a first supporting unit and a second supporting unit. When the second body slides towards at least one edge of the first body to a preset position, the first supporting unit and the second supporting unit can be unfolded to a preset angle for supporting. The connection part, the first supporting unit and the second supporting unit are connected through a pivoting shaft. According to the terminal device and the shell, the inclination angle can be flexibly regulated in the supporting process.

Each box comprises a box cover and a box body, a groove is formed in each box cover, and a first spring is arranged in each groove. Each first spring is connected with a movable block, and each movable block is fixedly connected with a U-shaped fixed rod. An electric push rod is fixed to the inner wall of each box body, an L-shaped fixed rod is fixed to each electric push rod, a connecting block is fixed to each L-shaped fixed rod, an alarm switch is arranged on each connecting block, and an electromagnetic suction cup switch is arranged on each supporting block. A second spring and an adsorption block are arranged at the bottom of each box body, each second spring is movably connected with a protection cover, and electromagnetic suction cups are arranged at the bottom ends of the protection covers. The anti-theft unmanned vegetable and fruit vending stand effectivelyachieves theft prevention, dual safety protection is achieved, a customer can buy vegetables and fruits autonomously, meanwhile, the placing inclination angle of the vegetable and fruit vending standcan be adjusted according to different vegetables and fruits, and the vegetable and fruit vending stand is wider in application range.

The invention discloses a modularization photovoltaic device. The modularization photovoltaic device comprises a base; a first photovoltaic component, a second photovoltaic component, and a third photovoltaic component, which are sequentially disposed on the base in a tiled manner. The base comprises four supporting leg components, and each two supporting leg components are respectively provided with a main cross beam, and the two main crossbeams are parallely arranged. The second photovoltaic component is disposed right on the upper part of the base by the two crossbeams, and the bottom end of the first photovoltaic component and the bottom end of the third photovoltaic component are provided with two secondary crossbeams, which are parallel to each other. During installation, the four secondary crossbeams are respectively cooperated with the end parts of the two main crossbeams in a sleeved manner, and then the first photovoltaic component and the third photovoltaic component are respectively disposed on the left side and the right side of the second photovoltaic component in a tiled manner. After dismounting, the four secondary crossbeams are fixedly cooperated with the supporting leg components by more than one fixing members, and then the first photovoltaic component and the third photovoltaic component are respectively vertically and fixedly disposed on the left side and the right side of the base. The modularization photovoltaic device has advantages of simple and compact structure, high modularization degree, and ability of facilitating fast capacity expansion and capacity reduction, fast disassembly and conveying.

The invention discloses experimental vessel carrying and transferring equipment for biological scientific research and a using method thereof. The experimental vessel carrying and transferring equipment comprises a carrying plate, a carrying table and a carrying disc, first hydraulic cylinders are vertically arranged at the four corners of the upper portion of the carrying plate, and inner supporting plates are movably connected to the upper portions of the first hydraulic cylinders through first hydraulic columns. The equipment has the beneficial effects that a third motor on the inner supporting plates drives the carrying table to rotate and adjust through a rotating shaft, the positions of experiment utensils can be rapidly changed, the first hydraulic cylinders push the carrying tableup through the first hydraulic columns to adjust the height, on one hand, it is guaranteed that the equipment can carry and move more experiment utensils at the same time, thus an operator can more conveniently take and place experiment utensils on the equipment; on the other hand, it is guaranteed that the carrying and moving range of the equipment for the experiment utensils is larger, and the equipment drives the experiment utensils to move more quickly; a plurality of rubber strips arranged on one side of each clamping arm at equal intervals are used for clamping the experiment utensils, so that an operating frame can operate and move the experiment utensils more stably.
