A method form identifying sensitive video based on light stream direction histogram and skin color stream deformation score includes downloading original video and decompressing video, calculating motion character of each frame, calculating said histogram and classifying said histogram by histogram sorter, calculating image character and dividing skin color by sorter for judging whether skin colorratio is over threshold or not and judging that this frame is sensitive image if motion character and image character are both sensitive.

The invention discloses a guiding and draining device for leachate in an incineration plant rubbish pool. The guiding and draining device comprises a rubbish incineration pool (10) and a leachate collecting pool (20) adjacent to the rubbish incineration pool (10); and a vertical pool wall (11) is arranged at the adjoining position of the rubbish incineration pool (10) and the leachate collecting pool (20). A rubbish discharging platform (50) is arranged above the leachate collecting pool (20); and a leachate collecting opening (30) with gratings (40) is formed between the lower section of the vertical pool wall (11) and the pool bottom of the rubbish incineration pool (10). An operation platform (60) extending to the vertical pool wall (11) is arranged at the position, below the rubbish discharging platform (50), of the top of the leachate collecting pool (20), and a gap (70) used for allowing a user to observe whether the gratings (40) are blocked or not is still reserved between the operation platform (60) and the vertical pool wall (11). The guiding and draining device is simple in structure, safe, reliable and convenient to use.

The invention relates to a method for improving the control effect of herbicides on wheat field weeds. The method comprises: treating wheat seeds with pyraclofen-ethyl, and then applying herbicides for control; wherein, the treatment is coating, seed dressing or soaking. Compared with the prior art, the invention can reduce the dosage of the herbicide, improve the control effect of the herbicide on weeds, and improve the safety of the herbicide on wheat.

The invention "a Paecilillium pekinense strain LYZ7 and its application" belongs to the field of microorganisms. The preservation number of the strain LYZ7 is CGMCC No.16487. The present invention unexpectedly finds that the bacterial strain belongs to a new strain, and names the strain as Paecilomyces Simplicillium pekinense. Based on the bacterial strain, the present invention also provides a tetracycline-degradable bacterial agent, a tetracycline biodegradation agent and a tetracycline biodegradation method. The bacterial strain LYZ7 of the present invention has a very significant degradation effect on tetracycline, and after 14 days of treatment, the degradation rate is as high as 89.21%.

The invention relates to a non-toxic famille rose pigment and a preparation method thereof. The pigment adopts natural raw mineral materials and industrial chemical raw materials, and comprises the following components in percentage by weight: 25 to 40 percent of quartz, 10 to 20 percent of feldspar, 20 to 30 percent of boric acid, 5 to 15 percent of alumina, 2 to 6 percent of lithium carbonate, 5 to 15 percent of light calcium carbonate, 0 to 3 percent of talc, 2 to 8 percent of zirconite, 3 to 6 percent of tin oxide, 0 to 3 percent of titanium oxide, 0 to 2 percent of cerium oxide, 0 to 5 percent of barium carbonate, 0 to 3 percent of magnesium carbonate, 0 to 5 percent of potassium nitrate, and 0 to 5 percent of sodium fluoride; and 0.5 to 2 percent of coloring metal oxide or 10 to 20 percent of nontoxic ceramic pigment are additionally or directly added into the components to prepare the product. The method well solves the problems that the famille rose is not white, famille or tender, has high expansion coefficient and the like after lead and arsenic are not added by adopting composite opacifier and controlling the proportion of flux components so as to prepare the non-toxic famille rose pigment with traditional famille rose decorating effect of Jingdezhen.
