A novel public key encryption scheme with multiple private keys is presented . the security of this encryption method depends on the difficulty of the decoding problem for block codes over finite fields . based on the encryption method , a pirate tracing scheme is proposed for the copyright protection of digital data . in this tracing scheme , for each legal copy of digital data there is a codeword buried in the corresponding decryption software or box . the scheme can extract the codeword efficiently , and uncover all authorized users involved in making the illegal copy by using a proper decoding algorithm if the number of such users is not more than the error - correcting capacity of a given code . compared with known tracing schemes , this scheme is efficient in performance , and easy in implementation . potential applicable areas of the encryption method include the protection of copyrights of various forms of digital data such as computer software and audio / video products 提出了一种新的具有多个私钥的加密方法.这种加密方法的安全性有赖于有限域上分组码译码问题的困难性.根据所提的加密算法,给出了一种适用于数字数据版权盗版跟踪方案.对于每一个数字数据的合法拷贝,给出的跟踪方案都分配一个分组码的码字与该拷贝的解密软件或者相关装置相对应.所提的方案能够有效地提取与解密软件或者装置相对应的码字,并进而利用所用分组码的译码算法找到所有参与非法拷贝制作的合法授权用户,其中,假设参与数字数据非法拷贝的合法用户数不超过所用码的纠错能力.与其他已有方案相比,所提方案具有更好的性能,并且容易实现.所提加密方案的潜在应用领域包括计算机软件、视频/音频等产品的数字数据版权保护方面

My nephew is not more than 1 age , is in the mouth period typically , to bite what he finds , once eat off one third of my book kang xi emperor on my bed , i don ' t care the book if he finished it , i only care , when he was in anus period , if he will shit a book of kang xi emperor out 我的小外甥不到一岁,现在是典型的口腔期,见什么咬什么,一次将我床上的一本《康熙大帝》吃掉了三分之一,就算他把这本书全吃了也没有什么,我唯一担心的是,他到了肛门期的时候会不会屙出一本《雍正王朝》来!
The research in software radio is not more than ten years , but has made a great many fruits , but it is too little to set up an integrated theory system , and software radio includes many areas such as modern communication system ( which includes modem source / channel encoding and decoding , equalization , encrypt and decrypt and so on ) , wideband antenna theory , digital signal process , microelectronics , computer and so on . this thesis mainly does research for modem in modem communication 软件无线电经过不到10年的研究,尽管取得了很多成果,但是对于建立一套完整的理论体系来说,还远远不够,况且软件无线电涉及的领域多、面广、发展快,如现代通信理论(含调制解调、信源信道编解码、均衡、加密解密等) 、宽带天线理论、数字信号处理、微电子、计算机等。
The results of the experiments have showed that the vibration of the head and the buttock mainly take place in the frequency of 0 . 5 ~ 20hz , the vibration acceleration of the passenger ' s head on the high - level sleeper bus at highway does not exceed 1 . 20 m / s2 , the buttock ' s vibration acceleration is not more than 1 . 00m / s2 , however the acceleration of the legs " vibration is less than 0 . 50m / s2 . the vibration experiments of trains were done on the hard and soft berths in the mountain diverged line and the plain main railway , the data showed that the vibration of the passenger ' s head and pelvis mainly took place in the frequency of 0 . 5 - 15hz , under this range , the acceleration of head ' s vibration do n ' t exceed 0 . 80m / s2 , the but tock ' s vibration acceleration is not more than 0 . 40m / s , the legs " vibration acceleration is less than 0 . 30m / s 数据分析表明,头部和臀部振动主要发生在0 . 5hz 20hz ,高档公路卧铺客车在高速公路上,头部振动加速度值一般不超过1 . 20m s ~ 2 ,臀部振动加速度值一般在1 . 00m s ~ 2以下,而腿部振动加速度值一般在0 . 50m s ~ 2以下;铁路卧铺客车卧姿乘客振动试验分别在山区支线和平原干线上运行的硬卧及软卧卧铺进行,数据分析表明,头部和臀部振动也主要发生在0 . 5 15hz ;平原干线的铁路软卧,头部振动加速度不超过0 . 80m s ~ 2 ,臀部振动加速度值不超过0 . 40m s ~ 2 ,而腿部振动加速度值则在0 . 30m s ~ 2以下。
Abstract : an imidazole - catalyzed acylation method of phthalic anhydride is applied to the determination of hydroxyl values of reinforcing agent is211 . the analytical error is 5 . 0 10 - 3 . the relative standard deviation of the method is less than 0 . 04 and its coefficient of variation is not more than 5 . 0 10 - 3 . hydroxyl values determined in different batch samples meet the design requirement completely . this method is rapid and simple , it is adaptable to conventional analysis 文摘:以咪唑催化邻苯二甲酸酐酰化的方法测定增强剂is211的羟值,准确度高,分析误差为5 . 0 10 - 3 ;方法精密度好,标准偏差小于0 . 4 ,变异系数不大于5 . 0 10 - 3 ,测定不同批号试样的羟值完全符合商标值,方法快速、简便,适用于常规分析。
With the sharply competition in international market , the enterprises in china choose m & a to expand and enter the international market . in view of the cases about m & a in china and oversea , however , the successful enterprises in m & a are not more than 15 % of these . the reasons of leading to failure in m & a are no good integration , especially in culture , to lost customers , to lost key staffs , so efficient integration must be considered before to choose the target enterprises , then manager need to evaluate the target enterprises , to help to choose the target enterprises at the beginning of m & a , and not lead to hard in the integration and decrease of value for not selecting the target enterprises 随着国际市场的竞争日趋激烈,我国企业相继采用并购的方式进行扩张,进入国际市场,然而,纵观国内外的并购案例,真正成功的案例不超过15 % ,导致并购失败的原因绝大多数存在于整合不利或整合无效,其中由于文化冲突、员工流失、客户流失等最为突出,因此在进行目标企业选择时就应该考虑是否能有效整合的相关事项,并进行评估,方便并购初期对目标企业的取舍,不至于造成目标企业选择不当而导致的整合困难和价值减少。
