The invention relates to an on-site counting method for phytoplankton in seawater, which belongs to the field of marine survey methods. The target water sample is taken and passed through a 200 μm sieve to make seawater sample P1; Shake and mix well to make a mixed sample H2, and inject the mixed sample H2 into 8 long-necked glass funnels on the chemical and biological process online monitoring system at the same time, and the solution flows into the lower container through the funnel under the action of gravity; The process online monitoring system automatically collects / records the capacitively coupled non-contact conductance σ data of the flowing mixed sample H2; when all the mixed sample H2 completely flows out of the long-necked funnel, the chemical and biological process online monitoring system automatically counts the inverted peaks that appear in each detection channel Number of type signals n 1 ,n 2 …n 8 The method of the invention can measure the quantity of phytoplankton in the seawater sample on site, which is simple and quick.

The invention discloses a measuring device of the inner wall size of a large rotary workpiece. The device comprises a pedestal, a mounting frame, a rotary mechanism, a longitudinal moving mechanism, a transverse moving mechanism, a leveling mechanism and a laser displacement sensor, wherein the pedestal is used for supporting other parts of the device; the mounting frame is used for mounting the device on a workpiece to be measured; the rotary mechanism is arranged between the pedestal and the mounting frame and used for driving the laser displacement sensor to rotate on the horizontal plane; the longitudinal moving mechanism is used for adjusting the position of the laser displacement sensor in the vertical direction; the transverse moving mechanism is used for adjusting the distance of the laser displacement sensor relative to a workpiece measuring point in the horizontal direction; the leveling mechanism is used for adjusting the posture of the laser displacement sensor to enable laser beams emitted by the laser displacement sensor to horizontally illuminate the workpiece measuring point; and the laser displacement sensor is used for measuring the distance from the workpiece measuring point to the sensor. The invention also provides a measuring system and a measuring method based on the measuring device. The space coordinates of the measuring point are determined through laser triangulation theory, so that the measuring precision is high; and the measuring position can be automatically adjusted. The device, the system and the method are suitable for field measurement of various large rotary shell parts.

The invention discloses an onsite simulated tester for the migration distance of a boulder under the trend effect. The tester comprises a pedestal, a simulated bed, a conductive film, electrodes, indicators and an elastic separator; the simulated bed is arranged on the pedestal, and a sealed accommodating space is formed between the pedestal and the simulated bed; the simulated bed includes an elastic fluctuating part; the conductive film is arranged in the inner wall of the fluctuating part; the electrodes are arranged on the pedestal, and correspond to relative recess positions of the fluctuating part respectively; the indicators are connected with the electrodes respectively; the elastic separator is arranged between the simulated bed and the pedestal; and the boulder presses down the simulated bed, so that the simulated bed is recessed and deformed, and the conductive film in the recessed position is connected with the electrode, the indicator indicates the location of the boulder, and migration distance data of the boulder is obtained. The onsite simulated tester realizes onsite actual measurement for the boulder migration process under the trend effect, has great significance in researching an evolution process from rubbles to the boulder, a transport process of rock and soil bodies in the bench, interaction between waves and the rock and soil bodies and the like, and is simple in structure, convenient to operate and helpful for large-scale popularization.
