An integrated module frame and racking system for a solar panel is disclosed. The solar panel comprises a plurality of solar modules and a plurality of splices for coupling the plurality of solar modules together. The plurality of splices provide a way to make the connected modules mechanically rigid both during transport to the roof and after mounting for the lifetime of the system, provide wiring connections between modules, provide an electrical grounding path for the modules, provide a way to add modules to the panel, and provide a way to remove or change a defective module. Connector mount assemblies are provided on the sides of the modules to simplify the electrical assembly of modules when the modules are connected together with splices and to simplify the final connection of external wiring to the module.

A cable connector assembly for a connection with an electronic equipment, includes a contact shaft for an electrical connection with the electronic equipment, a cable for an electrical connection with the contact shaft, a tubular sleeve covering on the contact shaft, and a metal tube with a bevel inner surface according with a bell-mouthed external surface of the tubular sleeve to be covered on the tubular sleeve.

The invention relates to a method for sewing and braiding hank yarns to be dyed. A machine head of a sewing and braiding machine is provided with a threading needle rod, a threading needle, a suspended bearded needle rod and a suspended bearded needle, wherein the threading needle rod makes vertical motion and horizontal movement; the suspended bearded needle rod makes horizontal movement; and the suspended bearded needle rotates on upper and lower surfaces of filaments. Due to a series of motion and repetition, the hank yarns to be dyed are formed. The sewing and braiding method is a bobbin thread-free sewing and braiding method, the defect that a bobbin thread or a lower thread hooking mechanism is needed in the sewing process in the conventional sewing technology is overcome, sewing conditions are reduced, the cost is saved, sewed items which have narrow inner surfaces or of which the inside is unavailable are freely sewn from the surface, the technical defect of the conventional braiding equipment is overcome, mechanical automatic continuous braiding can be realized, and the efficiency is high.

The invention provides a slope reinforcement device used for municipal construction engineering. The slope reinforcement device used for municipal construction engineering comprises a concrete frame protective plate and a protective layer, wherein the concrete frame protective plate is arranged on a slope. A plurality of hollowed-out areas are formed in the protective plate and used for planting green plants. The protective layer is a non-woven fabric protective layer and is arranged on the surface of the protective plate. The protective plate is fixed to the slope through an anchor rod. The anchor rod comprises an anchor ribbed rod body, a reinforcement rod head and a plurality of force hook heads, wherein the top end of the anchor ribbed rod body is fixedly connected with the reinforcement rod head, and the force hook heads are welded to the two sides of the reinforcement rod head correspondingly; and the anchor ribbed rod body is made of a steel stranded wire. According to the slope reinforcement device used for municipal construction engineering, the structure of the anchor rod is optimized, and thus the anchor rod is more suitable for shallow fixing. The force hook heads are obliquely welded to the reinforcement rod head, welded to the two sides of the reinforcement rod head in opposite directions correspondingly and obliquely arranged at the inclination angle of 30-45 degrees so that the prestress force applied to the anchor ribbed rod body can be increased easily, the force hook heads can be hooked in the slope more powerfully, and excellent pulling resistance is achieved.

The invention discloses a method for measuring a human tissue quasi-elastic coefficient. The method adopts a simplex optimizing method to determine the quasi-elastic coefficient of a human tissue, andreduces nine three-dimensional elastic coefficients to three quasi-elastic coefficients (for example, in a two-dimensional ultrasonic patient treatment plane or detection, four elastic coefficients are reduced to two quasi-elastic coefficients), and can save the calculation time. The invention also provides a human tissue quasi-elastic coefficient measurement method on the basis of the quasi-elastic coefficient measurement method, which adopts a secondary imaging method to measure relative change of the human tissue quasi-elastic coefficient, can thoroughly change the defects of ultrasonic images depending on the precision of elastic image instruments; change of the human tissue structure can be accurately determined according to the measured change; in addition, the invention also provides an ultrasonic detector or detection device matching the human tissue quasi-elastic coefficient, expensive imaging devices can be avoided, and the ultrasonic detector or detection device is low in price; and the detector can be accepted by public, and can be promoted and applied.

Thus, according to one aspect, the invention provides a system for mounting an abrasive tool to a drive plate of a polisher or grinding tool, the system comprising: an intermediate element mounted to a surface of the drive plate via a first securing means; and a second securing means for securing the abrasive tool to the intermediate element. The intermediate element may be a tool mounting plate and the second securing means is at least one pin and spring assembly. The intermediate element may be a ring and the second securing element comprises magnets and pins. The intermediate element may be a circular bracket and the second securing element comprises rotary slot attachment.

The invention relates to a multi-phase coating of a metal pole plate of a fuel cell for inhibiting columnar crystal and a preparation method of the multi-phase coating. The multi-phase coating coats the metal pole plate and comprises at least one group of coating units which are sequentially arranged outwards from the upper surface of the metal pole plate; each coating unit comprises a metal two-phase layer, a metal compound three-phase layer and an anti-corrosion compact single-phase layer; and the multi-phase coating is prepared by the steps of substrate surface pretreatment of the metal pole plate, metal two-phase layer deposition, metal compound three-phase layer deposition, single-phase layer deposition and the like. Interfacial tension can be changed by a second element in an interface phase according to a Gibbs adsorption equation; the wettability on a substrate during thin film nucleation is improved; and the roughness of the thin film surface is significantly reduced. Compared with the prior art, the multi-phase coating has the advantages that two-phase metals affect each other in growth and deposition processes, in summary, avoidance of a columnar crystal structure which is easily generated by a single-phase coating is facilitated, formation of an equiaxial crystal structure with more excellent properties of the compactness and the like is facilitated, and the lifetime of the metal pole plate of the fuel cell under the working condition of the fuel cell is finally prolonged.
