Its principle is use feed pump to put the premixed material into the host milling barrel in which proper mill medium is addedand reasonable designed arc line style blades are installed on the main axis symmetrically.Explosion proof machine transits the energy used for separating and milling to main axis through static electricity proof V tape belt to drive blade rotate in high speed, thus it will offer mill medium with high intensity function which can drive beads do random motion and bump with separated grain to create strong cutting force and then cut the material into ion or dissociation,thereby the material will keep in permanent ultramicron separation state.

其原理是利用送料泵浦将预先已搅拌好的物料送入主机研磨桶内，研磨桶内加入适量的研磨介质，合理设计的弧线型葉片对称地安装在主轴上，防爆電机通过防静電V型皮带把分散和研磨所需的能量传送到主轴上带动分散葉片高速转动，给予研磨介质以高强度的动能，带动珠子无规则运动与被分散物料之颗粒撞击产生强大的剪切力，使物料变为离子或游离子从而达到永久的超细微粒分离状态。

In this paper, we have proposed a flexible encryption blocks selection buyer-seller watermarking protocol integrated the RSA asymmetric encryption system and homomorphism mechanism to protect the ownership of digital contents and fit real life. And consider the secondhand transaction in the real life. We also propose a buyer-reseller watermarking protocol based on the flexible encrypt blocks selection buyer-seller watermarking protocol to offer a solution of secondhand transaction. In our scheme, it's more light data transport requirement than other schemes. All roles in protocol will benefit by their participation. Our scheme can overcome various of the known attacks and security problems in the buyer-seller watermark protocol, such as buyer's right problem, unbinding problem, piracy tracing problem, conspiracy problem, buyer's participation in the dispute resolution problem, man-in-the-middle attack problem and anonymous problem. Furthermore, the seller and arbiter can verify the buyer's watermark without decrypting it in our scheme.

本文除应用RSA非对称式加密与秘密同态机制，提出了一个符合现实生活中买卖交易行为、可弹性调整加密范围数位内容买卖浮水印协定，强化了目前研究中对於数位内容买-卖浮水印协定的安全性，并进一步的考量二手商品交易行为，在可弹性调整加密范围数位内容买卖浮水印协定基础上，提出一个结合数位内容二手买卖与盗版追踪的二手数位内容买卖浮水印协定，达到让参予买卖的角色可以在安全的情形下完成二手数位内容所有权的移转并从中获取相对应利益的目标的数位内容转卖浮水印协定来增强了目前数位内容买卖浮水印协定研究中对於二手交易欠缺之处，解决了数位内容买卖浮水印协定中所可能遭遇的重要安全性议题，如：买方权益、盗版追踪、资讯不连结、共谋、买方需要参与仲裁、中间者攻击及匿名性问题。
