数据恢复

Since 1960s, there has been a general trend of recovery in terms of water quality and invertebrate community.

摘 要：采用长系列数据，分析了影响泰晤士河潮汐河段生态状况的主要因素。1915～2006年的监测数据表明其生态状况经历了污染、恢复和稳定3个阶段，20世纪40～60年代是污染最重的时期，伴随着较高的水温、氨氮和生化需氧量以及较低的溶解氧含量，该时期少有底栖无脊椎动物的记录。

It consists of a low noise amplifier, mixer, limiter, FM/FSK demodulator with an external LC tank circuit or ceramic resonator, LPF amplifier, and a data slicer with clock recovery and an integrated data bit synchronizer.

You cantest floppy disks, search for bad sectors, repair bad sectors, format, quick format, recover data onbad sectors, make backups, mark/unmark bad sectors, erase data without using files, test floppy disk speed on reading.

你能够检查软盘，搜索被破坏的部分/磁道，修补磁道，格式化，快速的格式化，恢复关于被破坏的部分/磁道的数据，做出备份，标记被破坏的部分/磁道，清洗数据而没有使用文件，试验软盘速度。

This dissertation researches in the vibrant clipped data of a plane, proposes regression analysis, BP learning algorithm and cubic spline interpolation to forecast the clipped data.

以国产某型无人机空飞时振动传感器测得的振动削波数据为研究对象，选用回归分析法、BP神经网络法和三次样条插值法对削波数据进行预测恢复。

After finishing holistic analyses, and considering the specific and relative research on database technique"s application in the remote structural collaborative experiment, this thesis explores and discusses that the proposed database organization scheme can promote the efficiency of the data"s reposting in the Remote Structural Collaborative Experiment, the efficiency of the remote data exchange, and puts out the improving design compared with the NCREE system, that is to use middleware to realize the separation of the experimental process and DBMS and to set up buffer pool to solve the problems, such as to solve network replacement by getting back the experiment.

在完成了整体分析设计之后，针对数据库技术在远程结构协同实验中的应用作了具体的相关研究，探讨了本文提出的数据库组织方案在远程协同实验中可以提高数据入库效率以及远程数据交换效率以及对比NCREE系统设计提出了改进的设计思想，即采用中间件以实现试验进程与DBMS分离以及设立缓冲池以解决网络复位而要恢复试验等问题，并且还研究了在协同实验中分析中的常用数值积分算法，并着重探讨分析了算子分裂算法。

A process for deleting data that is intended to make the data unrecoverable.

删除数据的操作是为了使数据不再可以恢复。

By analyzing the results of LSNR measurements for samples with different components, and comparing with the media of Aprilis Corporation, we give the suggestion to optimize the material components in the future. In addition, based on the physical mechanism of intra-page crosstalk noise, we proposed the Pixel-Matched Spread Function, and a simplified deconvolution arithmetic to suppress the intra-page crosstalk noise.

另外，在分析数字数据全息存储中页内串扰噪声产生的物理过程的基础上，提出了像元匹配扩散函数的概念，并提出了一个反卷积算法来抑制页内串扰噪声，计算机模拟和实验结果都证明我们提出的PMSF算法可以有效的抑制页内串扰噪声，提高恢复数据页的保真度。

CDP systems may be block-, file- or application-based and can provide fine granularities of restorable objects to infinitely variable recovery points.

数据的变化被持续的追踪捕获；2。所有变化数据被存储到主存储之外的独立空间；3。恢复的目标时间点可以是任意的，不需要预定义。

Oracle automatically uses the lowest applicable level of restrictiveness to provide the highest degree of data concurrency yet also provide fail-safe data integrity.

Oracle 会尽可能地减少锁产生的影响，从而最大程度地保证数据的并发访问能力，并确保数据一致性及错误恢复。

The establishment of reverse tunnel makes it possible for the MH from foreign network to communication in the network whose touter has access filters.

采用隧道技术将发送给移动节点的数据包封装后转发到一个中间节点，然后由此中间节点解封后再将恢复出来的原始数据包转发到移动节点。

This brought fixed cost, but it also is meant at the same time use a source to won't make you singlehanded assume a problem.

这带来了一定的成本，但它同时也意味着使用开源不会让你独力承担问题。

He gained a small fortune in real estate.
