因此，开发出一套具有结构简单、控制精确、能够根据工况的实时变化自动调节油水比例等特点的柴油机油水在线混和自控系统势在必行。

Therefore, there is a need to develop a novel system of diesel online emulsifying combustion that is characterized as simple construction, accurate control, and variable water-fuel proportion.

其次，本文提出了一个具体可行的混和加密方案：用加密速度快分组密钥AES算法对控制信息加密；用安全性更高但加密速度慢的RSA算法来传递AES算法的密钥。

Then the paper puts forward a blending encryption project: using the AES algorithm to encrypt the controlling data, using the RSA algorithm to transfer the key of the AES algorithm.
