An additive (6) for degreasing and cleaning the surface (2) to be blasted and / or the blasting agent is provided, said additive comprising a granular material, which has a lower fracture strength than the at least one means for mechanically processing surfaces itself under the mechanical loads to which the blasting agent (4) is subjected during the blasting method.

The invention discloses a starting method and device, and meanwhile discloses a method and device for starting a kernel and a method and device for generating a kernel image. The starting method includes the following steps that kernel image fragments corresponding to the kernel image are copied to different sub regions of a kernel image loading space respectively; the kernel image fragments are re-positioned so as to start the kernel. By means of the method, codes and data in the kernel are randomly distributed in the kernel image loading space by using the fragments as units, fragmentizationof the kernel address is thus achieved, even if an attacker obtains the relative deviation of one kernel image fragment through a kernel address leakage loophole, the positions of other fragments cannot be calculated, the difficulty of reading and modifying the kernel is greatly increased for the attacker, and the safety of the kernel thus can be more effectively guaranteed.

The embodiment of the invention provides a Word document fragmentization method and device. In order to solve the problem that in the prior art, the retrieval efficiency is low when the target content is retrieved in a Word document, the Word document fragmentization method comprises the steps that firstly, all paragraphs of the Word document are obtained; secondly, according to the sequential order of the paragraphs in the Word document, the paragraph attributes of the paragraph are obtained in sequence, all the paragraph attributes which first appear in the Word document are extracted, and a paragraph attribute set of the Word document is generated; thirdly, a paragraph attribute recognition model is utilized to extract all headline paragraph attributes in the paragraph attribute set, and a headline paragraph attribute set is generated; fourthly, according to the headline paragraph attribute set, all headlines in the Word document are recognized, a headline tree of the Word document is generated, and the Word document fragmentization is achieved. Therefore, a user can directly retrieve the document paragraphs containing the target content in the fragmentized Word document or retrieve the target content in the headline tree of the Word document, and the retrieval efficiency is improved when the user retrieves the headlines of the Word document.

The invention discloses a crushing stone processing equipment for bridge engineering construction which is changed from throwing to accelerated crushing. Beneficial effects: the present invention utilizes the combination of the re-throwing structure and the gradual groove bar to change the parabolic trajectory of the crushed stones that are subjected to a single physical impact under the action of rotation, so as to avoid causing them to Concentrated wear leads to the deformation of the impact plate and affects the crushing diameter of the gravel. At the same time, it avoids the change of its parabolic trajectory under the action of the traditional impact plate rotation and buckle. The impacted gravel is jammed when it falls, so as to avoid its direct impact with the rotor, and accelerate the wear of the rotor, and use the jamming to split the gravel again, so as to realize the crushing effect on the gravel and avoid its impact on the rotor. While falling due to gravity, there is a rebound effect and it flies out.

The invention discloses a cable television program sharing and reconciliation method, terminal and system. The method comprises the following steps that a sharing system encapsulates at least one piece of cable television channel program information into a plurality of electronic gift bags according to purchase requests of users and shares to a target group; the sharing system receives a program order which is generated through activation after a member terminal in the target group receives the electronic gift bags; and the sharing system carries out reconciliation of the electronic gift bags and the program order, if the reconciliation is successful, the sharing system carries out interaction according to the program order and a cable television BOSS system in order to generate a BOSS order corresponding to group members, and the BOSS system opens corresponding programs for the group members. According to the method, the terminal and the system, the purchase and the use of ratings of television programs are innovatively modified, so that two-step separation, multi-person participation and fragmentation and circulation of the viewing right of the television programs are realized, and the brand-new Internet type television program viewing experience is brought. The conventional reconciliation mode of television services is modified, and the reconciliation method in a new mode is realized without changing the original functions of the BOSS system.
