In every period, do the following operations:# For each 8*8 block, do the discrete cosine transform, then take out direct current coefficient in each block, using the transformation above for each DC coefficient, the gold stands for the code of the spread-spectrum we use when embedding the different watermark bit in different frames, after all of the watermark information which we want to embed is embedded, then do the inverse discrete cosine transformation, and store the current frame in a new file.

于是利用DCT变换域的这点重要的几何不变性，我们可以推导出一种能够抵抗几何攻击的视频水印算法，即将所需要嵌入的水印信息以127位扩频序列作为辅助，以求和值形式嵌入到DCT变换后的每个宏块的每个DC系数当中，具体嵌入和提取算法如下：根据使用的扩频序列的长度N，基于相关的嵌入器需要选取包含N帧的视频子序列，令这N帧视频子序列作为一个嵌入周期，对于每N帧视频子序列做如下的操作，#即对于每个8×8的像素块进行DCT变换，然后取出每个DCT变换后的直流分量，对于每个DC系数，做如上所述的变换，其中gold为在第k帧中嵌入第i位水印信息时使用的扩频码字值，待将所有需要嵌入的水印信息全部嵌入后，再做反DCT变换，保存当前帧。

这个电流分从触摸屏的四角上的电极中流出，并且流经这四个电极的电流与手指到四角的距离成正比，控制器通过对这四个电流比例的精确计算，得出触摸点的位置。

Along with budget accountancy the variety of the environment, current accountancy of the government check foundation to exist the demand that can't adapt a public finance system reform, didn't reflect governmental funds sport completely, and current public finance budget the management and reform don't went with in response to;Can't reflect governmental financial standing completely from the angle of finance, in the aspects of guarding against a public finance liabilities risk the existence serious blemish, can't body now governmental"recessiveness obligation";Can't provide more government accountancy's informations toward the public and the direct section;Disadvantage in research with international usual practice comparison, indirectly cause government's efficiency lowly wait many problems.

随着预算会计环境的变化，现行政府会计的核算基础存在着不能适应财政体制改革的需要，没有全面反映政府的资金运动，与当前的财政预算管理和改革不相适应；不能从财务的角度全面反映政府的财务状况，在防范财政负债风险方面存在严重的缺陷，无法体现政府的"隐性债务"；不能向公众和监督部门提供更多的政府会计信息；不利于与国际惯例比较研究，间接导致政府效率低下等诸多问题。

China's interest rate from the current system, the market interest rates (such as money market, bond market interest rates) is clearly not in the list of interest rates; in direct control of the central bank's interest rate system, the re-lending and rediscount rate has not been very effective, because it few years the flow of adequate financial institutions makes little to rely on central bank loans and discount, and improve the reserve interest rate system with the reform of the general direction of inconsistency; Therefore, interest rates can only increase deposit rates or lending rates, both interest rates are in the current control and semi-control of interest rates.

中国的利率从目前的制度，市场利率（如货币市场，债券市场利率）显然不在列表中，利息直接控制的中央银行的利率制度，再贷款和再贴现率并不十分有效，因为这几年充足的流动金融机构几乎没有什么依靠中央银行贷款和贴现，提高准备金利率制度改革的总体方向不一致，因此，利率可只有增加存款利率或贷款利率，无论利率在目前的管制和半管制的利率。

A coil of low resistance and high inductance used in electrical circuits to pass direct current and attenuate alternating current.
