Nondestructive detection method for physiological index of plant leaf

The invention discloses a nondestructive testing method used for testing the physiological indexes of plant leaves on the basis of invisible-near infrared spectrum, which can carry out the quick and multi-parameter testing on the content of compositions such as chlorophyll, nitrogen, lutein, water and the like simultaneously. The method carries out spectrum collection on calibration samples, subsequently preprocesses the spectrum data, preferably selects the waveband, establishes the calibration model between the spectrum value and the standard value of the content of plant component, and collects the spectrums of the unknown samples; after the spectrum data is pre-processed, the selected waveband data are substituted in the calibration model so as to predict the content of the component to be measured; the technical proposal of the invention adopts full-spectrum information; the measured parameters have strong extensibility and the prediction precision and the model adaptability of the calibration model are improved; the trans-reflective measurement type adopted by the method adopts the spectrum sensitiveness and has stronger adaptability on the leaf type; and the improved wavelet analysis method can simultaneously eliminate the noise of the leaf spectrum data and carries out benchmark line calibration pre-processing on the leaf spectrum and can effectively improve the prediction precision.

Sweeping robot supplementary sweeping method and chip

The invention relates to a sweeping robot supplementary sweeping method and a chip. The method comprises the steps that entrance reference points of the boundary of each entrance of a swept region and an unswept region are selected preferentially, the best entrance point is determined, one point is selected from the best entrance point according to entrance selection conditions as a sweeping starting point, and region sweeping is performed on the basis of the preset sweeping conditions. According to the supplementary sweeping method, no any marking position point needs to be made, only endpoints of the entrance boundaries of the sweeping region and the unswept region in a raster map are adopted as entrance reference points for performing preferential selection, even if the shape of the unswept region is complex, the sweeping starting point of the unswept region can be more objectively, more flexibly and more accurately determined just by analyzing and judging the boundaries and selecting the best entrance point, and therefore the most suitable unswept region is preferentially swept. Meanwhile, according to the preset sweeping conditions, the region is swept, the problem that omitted sweeping caused by the existing mode that a zigzagged shaped sweeping is performed simply from the marked position point can be avoided, and sweeping comprehensiveness and integrity are ensured.

Method and device for traffic phase adjustment based on road traffic state

The embodiment of the invention provides a method and a device for traffic phase adjustment based on a road traffic state. Vehicle passing data at upstream and downstream intersections in a road section are acquired; according to identifiers of N passing vehicles and the time for passing across the upstream and downstream intersections, the parking times of the N passing vehicles are determined; according to the parking times of the N passing vehicles, the passing state in the road section is determined; and when the passing state in the road section is determined to be a congestion state, the traffic phase of the upstream and downstream intersections in the road section is adjusted according to the parking times of the N passing vehicles. As the passing state in the road section is determined according to the vehicle passing data at the upstream and downstream intersections in the road section acquired in real time, on one hand, the test cost is reduced, and on the other hand, the passing state in the road section is determined more comprehensively and objectively. When the traffic state in the road section is poor, the problem existing in the traffic phase of the upstream and downstream intersections in the road section can be timely determined, adjustment can be carried out, and congestion in the road section can be effectively alleviated.

A Comprehensive Evaluation Method of Fault Sealing in Volcanic Area

The invention discloses a volcanic zone fault sealing comprehensive evaluation method specifically based on Karamay oilfield volcanic rock development area. A volcanic zone fault sealing forming mechanism is mainly lithologic opposition and diagenesis. A lithologic opposition characteristic can be reflected in the aspect of the difference between the density of rock stratums on both sides. The diagenesis of a fault zone is affected by cross section pressure, closeness and the like. Through the filling of argillaceous debris and the injection of late fluid, the fault zone is strongly closed. According to the invention, a concept model of fault plane density difference is established; a variety of parameters (cross section normal stress, closeness index and the like) are combined to evaluate diagenesis closeness and docking closeness; closeness influence factors are induced; a weight factor is proposed; through a weight coefficient, a mathematical model is built to acquire a comprehensive factor; and the fault sealing is comprehensively evaluated. According to the invention, a variety of geological factors are considered; accurate requirements of fault sealing quantitative evaluation can be met; and the method can be widely applied to the field of oil and gas resource geological exploration and development evaluation.
