An integrally-formed three-dimensional (3D) bio-printing system capable of alternate feeding of multiple materials, comprising: an optical imaging unit and a light path conversion unit, wherein the optical imaging unit comprises an image processing unit and a projection unit, the image processing unit segmenting a 3D modeling graphic of a printed subject to form image information, the projection unit converting the image information into one or more optical images, and the light path conversion unit projects the imaged light paths into bio-ink that can be cured by light, so that the projected image can cure the bio-ink by means of the focus of light.

Imaging principle-based integrated color light 3D bioprinting system

A pile-side lateral static load device includes a jack system, a liftable jack cart, a loading jack fixing system, and a loading system. The jack system includes a jack body. The jack system is installed on the liftable jack cart through the loading jack fixing system. The loading system is installed on the loading jack fixing system, and the loading system includes counter-pressure loading systems and counter-tension loading systems. The pile-side lateral static load device has a simple structure, is convenient to install and operate, and can complete lateral loading and in-situ tests under different pile diameters, different tonnages and different precisions, so as to facilitate a simulation test of in-situ lateral loading of a pile.

Pile-side lateral static load device

The purpose of the present invention is to provide a light control agent and explore its application, and is expected to improve the tissue binding force and convenience of the existing biological glue material by providing a new reagent or material for biological damage or homeostasis. In one of embodiment, this invention provides an agent for repairing biological damage or homeostasis, wherein the agent comprises a natural biological macromolecule modified by the photo-responsive cross-linking group.

Agent for biological damage repair or hemostasis and the method thereof

An apparatus for testing tangential and normal resistance of an anchor chain and soil under an equivalent elastic boundary and a method therefor, and the apparatus includes a support frame, a transmission device (), an air pressure loading system, a test box (), a vertical displacement applying part (), a tangential anchor chain unit (), a normal anchor chain unit (), etc. The present disclosure can, by using a spring of equal stiffness to simulate the elastic boundary and being capable of overcoming an influence of boundary conditions, greatly reduce a size of the test box, thereby effectively saving materials and reducing difficulty of a test operation; moreover, it integrates the normal and tangential resistance tests into one, which can measure tangential and normal interactions of the anchor chain and the soil at the same time.

Apparatus for testing tangential and normal resistance of anchor chain and soil under equivalent elastic boundary

A towing anchor capable of extending wing plate and an installation method therefor are provided. The towing anchor includes a main anchor plate and two wing plates which can slide outwards relative to the main anchor plate and will not be detached from the main anchor plate. The main anchor plate is anchored with a mooring steel cable connected to a towing vessel. The main anchor plate is further provided with a limit cable-receiving groove, in which first, second and third fixed pulleys are respectively provided correspondingly to each of the two wing plates. One end of a tensioning steel cable is fixed to an inner edge of the wing plate, and the other end of the tensioning steel cable sequentially surrounds the third, second, and first fixed pulleys and then passes through an opening formed at middle position of the groove to be connected to the towing vessel.

Towing anchor capable of extending wing plate and installation method therefor

An embeddable seepage module capable of being embedded into an interface ring shear apparatus is disclosed, wherein: the seepage module includes an annular cylinder, a seepage pressure regulation system, a top plate and a bottom plate; the interface ring shear apparatus includes an upper shear box and a lower shear box; the annular cylinder, the top plate, the bottom plate, the upper shear box and the lower shear box form an internal pressure cavity and an external pressure cavity; the internal pressure cavity is able to realize the precise double control of the soil seepage pressure and water flow through the seepage pressure regulation system; the external pressure cavity is able to collect fine soil particles under pressure seepage. In the case of soil seepage-shear coupling, the seepage module is assembled firstly for seepage, and after completing the seepage, the external pressure cavity is removed for ring shear tests.
