Embodiments of the present application disclose an information generation method and apparatus applied to a terminal device. One embodiment of the method comprises the following steps: acquiring a video frame image captured by a target camera in real time; storing the acquired video frame image as an image to be processed; inputting the image to be processed into a pre-trained user attribute recognition model to obtain user attribute information corresponding to the user image included in the image to be processed. This embodiment enables local analysis of the viewer in front of the target screen in real time, obtains user attribute information of the viewer, can provide the reference for customizing the playing content of the target screen, and then can realize customizing the playing content for the current viewer of the target screen, improve the playing effect of the target screen, and reduce the uncontrollability of the remote network environment.

The embodiment of the invention provides a method for information recommendation. The method comprises the steps of predicting the probability that a first user clicks first information through a first model, and obtaining a click probability according to the first information recommended by the first user, predicting the probability that the first user does not click the first information througha second model to obtain a non-click probability, and taking the first information as alternative information recommended to the first user when the click probability is greater than the non-click probability, wherein the first model is different from the second model. According to the method, the alternative information obtained through screening and used for information recommendation is more targeted, the uncontrollability of the recommendation result determined according to experience can be reduced, and the conversion rate of the recommendation result is effectively increased. In addition, the embodiment of the invention provides a device for information recommendation, a medium and a computing device.

Provided is a semiconductor device manufacturing method for improving a side wall mask. In the semiconductor device manufacturing method, a barrier layer (2) and a sacrificial layer (3) are formed; by adopting a chemical mechanical polishing (CMP) process, parts of quite different left and right sides on the top portion of a side wall (4) are ground off, and the approximately rectangular part of the bottom portion of the side wall (4) is left and is used as a mask to carry out a subsequent side wall mask technology; in this manner, an undesired result occurring on the subsequent etching due to morphologic asymmetry of the side wall (4) may be reduced as far as possible.

The invention discloses a refining method of pitavastatin tert-butyl ester, which comprises the following steps: cooling and crystallizing a mixed solvent in which pitavastatin tert-butyl ester raw materials are dissolved, filtering, and drying; wherein, the mixed solvent It is a mixture of methyl tert-butyl ether and non-polar organic solvent; the non-polar organic solvent is n-hexane, n-heptane, cyclohexane, n-pentane, cyclopentane, octane or isooctane. According to the refining method of the present invention, the isomer content in the obtained pitavastatin tert-butyl ester is low, and the refining effect is good. Epimer impurity 1, epimer impurity 2 and enantiomer impurity The contents are all below 0.05%. Moreover, the refining method of the present invention has high yield, low uncontrollability, simple operation, is suitable for large-scale industrial production, and can prepare high-purity pitavastatin calcium.

The invention provides a genetic algorithm-based residual static correction calculating method. According to the method, the size of a population, the generation of the population and the variation rates of individuals are calculated with allowed maximum time shift quantity, and therefore, residual static correction quantity can be calculated automatically, quickly and efficiently, and the improvement of the section quality of subsequent processing can be benefitted.

The invention discloses a non-slitting construction structure of a concrete super-flat terrace. The construction structure comprises a concrete terrace and a terrace foundation poured in the concreteterrace, wherein the terrace foundation comprises a partition plate network, a terrace steel bar layer, and a supporting mechanism for supporting the partition plate network and the terrace steel barlayer; the supporting mechanism comprises a plurality of supporting rings arranged in an array mode; and an auxiliary supporting frame is arranged between every two adjacent supporting rings arrangedin the same row and between every two adjacent supporting rings arranged in the same column in the supporting mechanism. According to the construction structure, the super-flat terrace is subjected tonon-slitting construction by arranging the partition plate network, the terrace steel bar layer and the supporting mechanism for supporting the partition plate network and the terrace steel bar layer; the height of main supporting frames, transition supporting frames and the auxiliary supporting frames can all be adjusted through adjustment bases so as control the elevation of the partition platenetwork; and the surface finishing operability is controlled by using the partition plate network, the uncontrollable property of concrete surface finishing is effectively reduced, and the smoothnessof the concrete surface is improved.
