The invention provides a Dangshan pear genetic transformation method. The Dangshan pear genetic transformation method comprises the following steps: (1) constructing a genetic transformation receptor; (2) culturing agrobacterium tumefaciens and preparing infection solution; (3) carrying out infection and coculture; (4) carrying out sterilization culture and screening culture; and (5) carrying out resistant callus GUS (glucuronidase) staining identification. The Dangshan pear genetic transformation method has the advantages that Dangshan pear callus is taken as the receptor, NptII is taken as a marker gene, GUS gene is taken as a reporter gene, Dangshan pear genetic transformation is carried out by adopting an agrobacterium EHA105 mediated process for obtaining positive resistant callus, and then redifferentiation is carried out by virtue of the positive resistant callus for obtaining test-tube plantlets; meanwhile, a method for carrying out genetic transformation by firstly inducing resistant callus by virtue of fresh treetop, taken as an explant, grown the same year of Dangshan pear is firstly established, content of phenolic substances in fresh treetops of the Dangshan pear in spring is low, less germs are carried, both inoculation browning rate and contamination rate are low, materials are available, callus induction ratio is high, and demand of genetic transformation can be met.

The invention relates to a geological mapping technology, discloses a three-dimensional laser scanning-based engineering geological mapping method, and solves the defects of low efficiency, low precision and large later workload in a measurement scheme of a geological spatial location in the traditional geological mapping process. The method comprises the following steps: a, obtaining point cloud data and geological object image information in a three-dimensional laser scanning manner; b, inputting the point cloud data and the geological object image information into a computer, building a three-dimensional geological model containing the image information; c, describing the geological feature points, geological feature lines and geological feature surfaces according to the geological characteristics on the three-dimensional geological model, and calculating geological attributes; d, inputting the obtained geological feature points, geological feature lines, geological feature surfaces and geological attributes into a management database; e, finishing geological information inputting and inquiring and geological map generation functions according to the data in the management database. The three-dimensional laser scanning-based engineering geological mapping method is applicable to mapping of an engineering geological body.

The invention discloses a swing bolster load testing method. The method comprises the following steps of: 1) machining a centre plate force-measuring seat at a centre plate of a swing bolster, machining a side bearing force-measuring seat at each side bearing of the swing bolster, installing a centre plate force-measuring sensor component and a side bearing force-measuring sensor in the centre plate force-measuring seat and the side bearing force-measuring seat respectively, and installing the swing bolster on a bogie; 2) actually measuring during vehicle operation and acquiring signals measured by the centre plate force-measuring sensor component and the side bearing force-measuring sensor through a signal acquisition device; and 3) calculating a load-time history at the centre plate andthe side bearing on the basis of the signals acquired by the signal acquisition device. Because centre plate force, the offset of the centre plate force and side bearing force are obtained in a way of direct measurement, the test precision of the centre plate force can be obviously improved; the steps for calibrating the load in a lab can be reduced; the period of test work is shortened; and human power and material resources are saved.

The invention discloses a lathe for processing castings, which includes a fifth motor, an auxiliary support mechanism and a chip removal mechanism. The invention sets the auxiliary support mechanism on the left and right sides of the sliding frame, and drives the rack to the right by pushing the rotating rod. At the same time, the rack drives the sector gear and the curved plate to rotate, so that the curved plate pushes the transmission rod and the support plate to move upward and fit on the bottom of the iron rod, which achieves the auxiliary support of the copper rod and makes the copper rod processing process more stable. Beneficial effect is that by setting the chip removal mechanism inside the base, the eccentric wheel is driven to rotate by controlling the energized output shaft of the drive motor, and the eccentric wheel drives the piston to slide left and right through the rotating plate, and the chips generated by processing are driven by the pressure difference It enters the top surface of the sloping chip removal plate through the chip removal hole, and enters into the collection frame for collection, so as to achieve the beneficial effect of quickly collecting the generated chips and reducing the workload in the later stage.

The patent of the present invention relates to the technical field of non-destructive testing of construction engineering, in particular to a method for detecting the repair quality of concrete cracks. Combining with the amplitude-frequency characteristics after crack repair, a new method for quantitatively judging the degree of crack repair is proposed. Quantitative The results of the repair degree and the test error range of this method are obtained. The research of this invention belongs to the research field of non-destructive testing technology in construction engineering. This method can be used in the process of repairing cracks in concrete beams such as buildings and bridges. Repair quality inspection has a good reference.

The invention relates to the technical field of painting tools, and specifically discloses a paint bucket, which includes a bucket body and a bucket cover. The bucket body is concavely provided with an accommodation chamber for accommodating paint, and the bucket lid is arranged on the bucket mouth of the accommodation chamber and is used to cover the bucket mouth. A protruding structure protrudes from the bottom of the accommodating chamber. The protruding structure includes a first end away from the barrel mouth and a second end connected to the side wall of the accommodating chamber. The cross-sectional area of ​​the first end is smaller than that of the second end. One end is provided with an opening device, and the opening device can communicate with the inner wall and the outer wall of the first end, so that the paint can flow out from the first end. The paint bucket of the present invention reduces the cost of cleaning or cleaning residual paint, and also improves the utilization efficiency of remaining paint, facilitates the recycling and reuse of paint buckets, helps users respond to the policy guidance of garbage classification, and also reduces the later period of paint users Workload and waste disposal costs.

The invention provides a gas pre-processing and sampling collector of an underground mine containing a large amount of dust, and relates to the field of mines. The gas pre-processing and sampling collector comprises a support bottom plate and a spherical shell, wherein a air-blowing control mechanism is arranged in the spherical shell, a side-surface support plate is welded onto a surface of the support bottom plate, a handle is welded onto a surface of the side-surface support plate, a liquid-gas collection mechanism is arranged on the surface of the side-surface support plate, and a storagebattery is arranged on the surface of the side-surface support plate. In the gas pre-processing and sampling collector of the underground mine containing a large amount of dust, an arc baffle body isarranged, on one hand, a second suction pipe can be matched with an arc sealing plate to guide an air direction, so that the air direction is in chaos; and on the other hand, a surface of the arc baffle body can be used for diverting water, so that the water can flow to an inner wall of the spherical shell and flows along the inner wall of the spherical shell, and the problems that a conventionalgas sampling device is not convenient to pre-process and subsequent sample detection is easily affected are effectively solved.
