The invention discloses a method for determining the number of stereoscopic image subjective assessment testees and experiment data, and relates to the field of stereoscopic image quality subjective assessment. The method comprises the following steps of through analyzing preprocessing data, determining the number of the subjective assessment testees by perverting a confidence interval formula to shorten an experiment cycle and reduce the cost; performing a subjective assessment experiment by utilizing the determined reasonable number of qualified testees, including the processes of establishing a stereoscopic image database, selecting reasonable testing environmental conditions, selecting the testees according to standards and training and testing the testees; lastly, according to the image quality subjective assessment standard regulation and the Grubbs' test method, eliminating abnormal testees and reasonably screening abnormal data in experiment data to avoid the influence of the testees, the experiment environment and other uncertain factors on the accuracy of an experiment result. The method is based on stereoscopic image quality subjective assessment, and the accuracy of the experiment data result is improved from the angle of statistics.

The invention relates to a method for identifying bacillus coagulans, and particularly relates to a novel molecular biology method for identifying bacillus coagulans. By adopting the method, a specific primer HFQ1 / HFQ2 is designed for a specific deoxyribonucleic acid (DNA) sequence of a bacillus coagulans gene, polymerase chain reaction (PCR) amplification detection is carried out on genome DNA of a to-be-detected sample by using the primer, and a bacillus coagulans strain can be identified to the level of seeds. A practical method which is more accurate and easier to operate is provided for identifying the bacillus coagulans, and classification and research work of the bacillus coagulans strain can be facilitated.

The invention discloses a mixed reality-based electric appliance test method and device. The device comprises an acquisition unit, a display unit and a somatosensory unit, wherein the acquisition unitis used for acquiring three-dimensional scene information of an electric appliance in a first room and somatosensory information of a plurality of sites in the first room; the display unit is used for displaying a virtual first room for a tester according to the three-dimensional scene information; and the somatosensory unit is used for enabling the tester to obtain somatosensory of correspondingsites in the first room according to the current sites of the somatosensory information and the tester in the virtual firs room. Through displaying the virtual first room, the tester can obtain visual experience same as the first room and the tester can obtain somatosensory same as the first room, so that users do not need to reach the first room to carry out electric appliance test, thereby saving the roundtrip time, saving the experiment resources, reducing the cost, enabling the tester to test electric appliances at a plurality of different places, and improving the test efficiency.

Provided is a device for analyzing and detecting reaction gas phase products, including a reaction unit, a separation unit, a detector and the like. The reaction unit is a high-pressure reactor, and there are pressure gauges, air inlets and outlets on the lid. One end of the inlet is connected to the gas source through a pipeline and a regulating valve, and the other end is connected to the high-pressure reactor; one end of the outlet is connected to the To the high-pressure reactor, the other end is connected to the separation unit through pipelines, regulating valves, and gas flow meters. Finally, the gas in the reaction unit is analyzed through a detector. There is an electric furnace on the periphery of the reactor cavity to provide the required temperature for the reactor. By changing the filling mode of the high-pressure reactor and the structure of the lid, the invention can be used not only for investigating the gas-phase catalytic reaction efficiency, but also for detecting some gas-phase products produced in the reaction process, and has simple structure, convenient operation and low cost.

The invention discloses an enrichment detection method and application of five antitumor drugs in a blood sample. The method comprises the following steps: adjusting the pH value of the blood sample by using an alkaline solution; enriching a target object by adopting a mixed mode filler with C8 (C18) and anion exchange capacity, then using liquid chromatography-tandem mass spectrometry for analysis, and establishing a standard curve by an internal standard method to calculate the concentration of the drugs in the blood sample, wherein the concentrations of anti-tumor drugs related to three structural types can be simultaneously determined. The method has the advantages of high flux, quickness, high extraction recovery rate and no matrix effect, meets the quantitative requirements of various mass spectrometric devices, and can be applied to blood concentration monitoring of the five drugs clinically.
