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.
