大地

At least he had remembered "broad meander valley," while looking at his map and the scenery.

不过他总算记住了一个曲流宽谷，而且是对着地图和大地记住了它。

Therefore, it can greatly improve the working conditions of workers, accelerating industrial production mechanization and automation pace.

Towards the outside looking Mengmenglonglong rain in the day, Hill has also appeared mysterious, the Mende of tea have been able to Yang Yang of the Yaoban, as if the rain in the enjoyment of the moisture in the bloom of the rain alarming Read It washed off their land, but also nourishes the people's heart, so that everything can clean it.

向着屋外看去，雨下得天蒙蒙胧胧的，山也显得神秘起来，被闷得病怏怏的茶树都挺起了腰板，好象在享受着雨水的滋润，在雨中绽放着惊人的神采，它洗刷了大地，也滋润了人们的心田，使一切都干干净净的了。

Felix Mendelssohn traveled extensively from age 20 to 23, finding inspiration for his music in places visited.

身为银行家之子的孟德尔颂，曾在年轻时游历英、义、瑞、法等国，深印脑海中的山川美景以及各地的奇风异俗大大地开拓了他的音乐视野。

As mentioned Live/Google maps use a Mercator projection, but although their datum is based on WGS84, they use a sphere instead of an ellipsoid.

上文所说Live Map / Google Map 使用墨卡托投影，但虽然他们的大地基准应该是基于WGS84的，他们用球体模型替换了椭球体模型。

As we controlled this system of void spaces or landscape spaces, we systematically and enthusiastically abandoned any claim of control over the residual lands and thought that they would probably turn into what the French call "merde."

因为我们控制了由空地和大地景观组成的系统，我们就能够主动地有步骤地放弃控制剩余的土地，并设想它们能够发展成法国人所说的"merde"。

The security of PKI system itself is especially emphasized during the system design and implementation process, which is in accordance with the pervasive characteristic of PKI. Second, the concept of a Trusted Key Management Center is introduced for the first time. This technology greatly strengthens key management practices and allows for smooth transition from PKI to Key Management Infrastructure. Third, certificate status mechanisms are investigated in depth, and a certificate revocation performance simulation system is devised. All these work will provide guides to practice and employment of PKI applications. Based on time constraints, a new taxonomy for authenticated dictionaries is proposed. Fourth, formal analysis ofOCSP protocol is carried out; then an efficient and scalable OCSP system is developed. Fifth, the special requirements caused by the working environments of Wireless PKI are analyzed. Based on communicative hashing and dynamic Merkle hash tree, an efficient certificate status validation method suitable for WPKI is presented. Sixth, one important kind of fair exchange protocols is studied, and a new CEMBS based on RSA cryptosystem is proposed. Afterwards, a novel fair exchange protocol totally based on RSA signature scheme is devised.

在系统设计和实现的过程中，考虑到PKI作为普适性安全基础平台的特点，特别强调PKI系统自身的安全性；第二，首次在PKI系统的设计中提出了"可信密钥管理中心"的概念，这一独特设计大大地强化了密钥管理功能的实施，为PKI向密钥管理基础设施的平滑过渡提供了良好的技术准备；第三，对证书状态验证机制进行了深入研究，设计了证书状态模拟系统，以指导PKI系统和应用的部署和实施；在此基础上，基于时间约束首次给出了认证字典的一种新的分类方法；第四，对OCSP协议进行了形式化分析，设计和实现了一种高效、可扩展的OCSP系统；第五，分析了WPKI工作环境对设计安全基础平台提出的特殊要求，结合无线移动设备的具体特点，基于可交换杂凑函数和动态Merkle杂凑树设计出了一种适用于WPKI环境的高效证书状态查询机制；第六，对一类公平交换协议进行了深入的研究，从设计公平交换协议的密码基础结构出发，提出了一种新型的基于RSA密码体制的高效CEMBS；在此工作的基础上，设计了一种基于RSA密码体制的最优化公平交换协议。
