At present, a cheap, efficient and feasible hot-line sales system is in critical need. Against to the problem of old system in security, real time and upgrading, some new technics , such as System Develop Model, GPRS, Terminal OS, System Security and Data Backup, are applies to build a strong and smart system.

鉴于彩票销售系统的现状，急需推出一套廉价、高效并且可行的全热线销售系统，针对原有准热线系统的安全性、实时性以及维护升级等存在的弊端，提出了改进及改造的方案，同时探讨了其中用到的几点关键技术：前端、通信、后台、系统安全性以及数据备份手段等，最终实现全热线彩票系统的实施及应用。

Therefore, it is serious to evaluating the biosafety of transgenic rice, especially for eco-safety to common wild rice.

因此，转基因水稻的安全性评估显得十分重要，尤其是对普通野生稻影响的生态安全性评估。

QL have the same height as the chain after it connected, so the surface will be smooth. Beside, the heights of chutes are the same, the interval become smaller. The safety is higher than before. Moreover, we add the special tenons on the up and down each side, which can make the QL safer. Those special skills ensure the safety and won't be slipped under the normality.

QL 安全扣在组装后与链条为同等高度，故其小轴不会有凸出的问题，且因全部滑移面高度相同，故其间隙会变小，增加其安全性；另在 QL 安全扣的小径部两侧增设多重的卡掣块，形成多重保护，在正常使用的状态下无脱落的可能性，确保其使用上的安全性。

Quantum cryptology is a new method for secret communications. Compared to the classical cryptography, the greatest advantages of quantum cryptography are provable security and detectives; this is because the security of quantum cryptography is ensured by quantum no-cloning and Heisenberg's uncertainty principle that instead of relying on some complex mathematical problems.

量子密码技术是一种实现保密通信的新方法，它比较于经典密码的最大优势是具有可证明安全性和可检测性，这是因为量子密码的安全性是由量子物理学中量子不可克隆性和Heisenburg测不准原理来保证的，而不是依靠某些难解的数学问题。
