    • A chemical vapor deposition method comprises steps of: a) injecting a source gas into a chamber so that the source gas is adsorbed on a substrate; b) injecting a purge gas into the chamber for a predetermined period of time so that the source gas remaining in the chamber is purged; c) injecting a reactant gas into a plasma generating portion, and generating plasma at the plasma generating portion by applying a first-level RF power source to a RF electrode plate so that radical of the reactant gas is adsorbed on the substrate; d) injecting a purge gas into the chamber for a predetermined period of time so that the reactant gas remaining in the chamber is purged; and e) applying a second-level RF power source to the plasma generating portion at the step a), b) and d) while the steps a) to d) are being repeated.

    • Disclosed herein is a method for improving the formability of an aluminum alloy sheet by locally modifying the surface of the aluminum alloy sheet. The method comprises: a sheet fixing step of fixing a sheet to be locally surface-modified; and a local surface modification step comprising adhering a probe closely to a region of the fixed sheet, which is in need of surface modification, by the application of pressure, and then rotationally moving the probe on the region at high speed. According to the method, the region of the sheet in which a fracture can occur due to the concentration of strains and stresses during the formation of the aluminum alloy sheet into a product is subjected to local surface modification so as to improve the formability of the aluminum alloy sheet compared to the parent metal, so that the aluminum alloy sheet can be easily formed into a product. If necessary, the friction coefficient of the probe can be changed by forming various shapes of fine embossments or fine protrusions on the lower surface of the probe, which comes into contact with the sheet, so that plastic flow can be changed to adjust the depth of the plastic region of the sheet, thus further improving the formability of the sheet.
    • 本文公开了通过局部改变铝合金板的表面来提高铝合金板的成形性的方法。 该方法包括:固定待局部表面改性的片材的片材固定步骤; 以及局部表面改性步骤,包括通过施加压力将探头紧密地粘附到需要表面改性的固定片材的区域上,然后高速旋转地移动该区域上的探针。 根据该方法,由于在将铝合金板形成产品期间的应变和应力集中而发生断裂的片材的区域进行局部表面改性,以提高铝的成形性 合金板与母体金属相比,使得铝合金板可以容易地形成为产品。 如果需要,可以通过在与片材接触的探针的下表面上形成各种形状的精细浮雕或细微突起来改变探针的摩擦系数,从而可以改变塑性流动以调节深度 片材的塑料区域,从而进一步提高片材的成形性。

    • A method and apparatus for recording image data, which minimizes data losses due to exceptional situations. The method includes storing image data in at least one fragmented file, each file having a predetermined size and creating one image data by gathering the fragmented files. Before creating the one image data, meta information on the at least one fragmented file may be updated, and the one image data may be created by gathering the at least one fragmented file based on the updated meta information. Accordingly, even if recording abnormally ends due to an exceptional situation, image data can be restored using the metadata, and the image data can be stably recorded by minimizing data losses.
    • 一种用于记录图像数据的方法和装置,其最小化由于异常情况导致的数据丢失。 该方法包括将图像数据存储在至少一个分段文件中,每个文件具有预定大小,并通过收集分割的文件来创建一个图像数据。 在创建一个图像数据之前,可以更新关于至少一个分段文件的元信息,并且可以通过基于更新的元信息收集至少一个分段文件来创建一个图像数据。 因此,即使由于异常情况而异记录记录,也可以使用元数据恢复图像数据,并且可以通过最小化数据丢失来稳定地记录图像数据。
