一方面，没有显式地标明丢失的数据，而只是通过不存在的行和时间戳进行了简单的标记。
For one thing, missing data is not explicitly indicated, but is simply marked by an absent line and time stamp.
对于行修改时间戳列(只针对这种列)，如果该列使用IMPLICITLYhidden属性定义，那么当对表列进行隐式引用时，不会对该列执行外部化。
For row change timestamp columns only, if the column is defined with the IMPLICITLY HIDDEN attribute, then it is not externalized when there is an implicit reference to the columns of the table.
这意味着，在SQL路径中，只有在最后一次显式绑定时间戳之前定义的全局变量才会进行名称解析。
This means that only global variables in the SQL path that were defined before the last explicit bind time stamp are considered for global variable name resolution.
隐式隐藏列：从兼容性方面来说，这个特性有助于将行修改时间戳列应用到现有表和应用程序。
Implicitly hidden columns: For compatibility, this feature eases the adoption of the row change timestamp columns to existing tables and applications.
为此，必须半交互式地提供资源名。否则，参与者完全可以迟签他们的日期戳的日期，制造出创建速度很快的假象。
To make this work, a resource name has to be provided semi-interactively -- otherwise, a candidate could just post-date their datestamp to give a false impression of rapid creation.
本课题主要研究分布式并发控制和时间戳顺序方法，在此基础上采用了并发控制方案。
The paper describes principles of concurrency control in detail, recommending the time-stamp order method.
比特币也使用广为人知的“对等分布式时间戳服务器”来验证数字硬币没有“双重使用”——换句话说就是伪造。
Bitcoin also USES a widely-published "peer-to-peer distributed timestamp server" to verify that the digital COINS have not been "double spent" -in other words, counterfeited.
纱窗的网格很密，撞击大楼的喷气式飞机就像是戳纱窗的铅笔，这对纱窗的整体没什么影响。
This intense grid and the jet-plane is just a pencil puncturing that screen netting. It really does nothing to the screen netting.
