The invention relates to a self-adaptive optical image high resolution restoration method combined with frame selection and blind deconvolution, comprising the following steps: firstly, a short exposure image sequence gn (x, y) is recorded when a self-adaptive optical closed loop is corrected; shannnon entropy of each frame of image in the sequence is calculated; a degraded image gm (x, y) with lower entropy is selected for blind deconvolution image restoration; secondly, an initial value hm (x, y) of a point spread function is generated by utilization of random phase; thirdly, a target f(x, y) is estimated by using the gm(x, y) and the obtained hm (x, y), and an estimated value f(x, y) is obtained after addition of positivity limitation on the target; fourthly, an estimated value hm (x, y) of the point spread function is obtained by using the gm (x, y) and the f(x, y), and an estimated value h(x, y) is obtained after addition of positivity limitation in the same way; fifthly, inspection is made whether an iterated value h(x, y) and an iterated value f(x, y) meet iteration stopping requirements or not; if the iterated values do not meet the iteration stopping requirements, the third step is returned; if the iterated values meet the iteration stopping requirements, circulation is stopped and the f(x, y) and the h(x, y) are outputted. The invention has the advantages of effective improvement of restoration quality, acceleration of convergence rate, capability of well compensating correction capability under hardware limitation of a self-adaptive optical system, and improvement of imaging quality.

The invention relates to the field of soil restoration, especially relates to the field of restoration of soil polluted by heavy metals, and particularly relates to a passivation agent for cadmium polluted alkalescent soil and a restoration method. The passivation agent is prepared from montmorillonoid and cow dung. The dosage of the passivation agent is 16%. The passivation agent formed through combination of montmorillonoid and cow dung can remarkably reduce the concentration of effective state Cd in the polluted farmland soil. Meanwhile, a test proves that the passivation agent formed through combination of montmorillonoid and cow dung has a better passivation restoration effect compared with independent application of cow dung or montmorillonoid, and the passivation rate is obviously higher than the sum of the passivation rates of montmorillonoid and cow dung. When the application rate of the passivation agent is 16%, the passivation rate can be as high as 81.48%. Therefore, the passivation agent provides a more effective new route for restoration of the alkalescent farmland soil polluted by the heavy metals.

The invention discloses an in-situ vibration wash restoration method for a polluted soil body. The method comprises the following steps: 1) determining pollution character and range of the soil body, and selecting and determining the type of washing fluid; 2) dividing the polluted soil body into a plurality of blocky soil bodies, and arranging seepage-proofing baffles on the bottom surface and four sides of each blocky soil body respectively for separation; 3) digging a liquid collecting trough in a clean soil body at one edge of the polluted soil body; 4) enabling the most marginal blocky soil body to be adjacent to the liquid collecting trough, and forming a plurality of through holes in the seepage-proofing baffle facing to the liquid collecting trough; 5) conducting vibration wash restoration on blocky soil body adjacent to the liquid collecting trough; 6) draining the liquid collecting trough, ploughing restored blocky soil body into the liquid collecting trough, forming a new liquid collecting trough in the original position of the restored blocky soil body, and repeating the step 4) and 5); 7) repeating the step 6) until the whole polluted soil body is completely restored. The in-situ restoration of the soil body is realized, the cost of soil body restoration is reduced, and the restoration efficiency of the polluted soil body is improved.

An embodiment of the invention provides a short message restoration method and device; the method comprises: acquiring from a mobile terminal, a short message backup file to be restored; writing in a memory, short messages in the short message backup file via at least two divisions, and writing from the memory in a short message database via at least two divisions. Since interval of time for the two divisions of writing the short message backup file into the memory and writing from the memory to the short message database is generally short, normal execution of the whole restoring operation is guaranteed; in the case of the short message backup file having high data quantity, part of data are written in the memory each time and then written into the database; the memory is reused, less data can be written into the memory each time, usage of the memory is reduced, it is guaranteed that writing is within the bearing range of the memory, memory exceeding is avoided, and normal running is guaranteed.

The invention discloses an environment-friendly type ecology reconstruction restoration method used for eutrophic water body. The environment-friendly type ecology reconstruction restoration method used for eutrophic water body comprises following steps: a first agent is uniformly sprayed into a water body for restoration so as to obtain a first treated water body; a second agent is uniformly sprayed into the first treated water body so as to obtain a second treated water body; gorgon Euryale is planted in the second treated water body in rows at a plantation coverage rate of 70%, and one month later, a third treated water body is obtained; the gorgon Euryale plantation coverage rate is controlled to be 50%, Hydrilla verticillata is planted between each paint of adjacent rows of gorgon Euryale at a plantation coverage rate of 20%, and one month later, a fourth treated water body is obtained; the gorgon Euryale plantation coverage rate is controlled to be 15%, more Hydrilla verticillatais planted between each paint of adjacent rows of gorgon Euryale to control the plantation coverage rate of Hydrilla verticillata to be 25%, and one month later, ecology reconstruction restoration isrealized. The environment-friendly type ecology reconstruction restoration method is capable of improving water quality effectively, realizing water body ecology reconstruction restoration, and is high in market value and social value.
