数据恢复

The backup and recovery of the system is an important part of the data backup and recovery field.

系统的备份和恢复是数据备份恢复领域中的一个重要部分。

Three altimeter data——Geosat/GM, ERS-1/35day and Topex/Poseidon, and two gravity recovery methods —— inverse Stokes formula with 2DFFT and along-track vertical deflection with 1D Hilbert Transform, are used in this section. The second method is developed independently by author on the basis of the Laplace's equation in Cartesian system.

主要利用三颗卫星测高数据——Geosat/GM、ERS-1和Topex/Poseidon，采用了两种不同的重力异常恢复技术——Stokes公式逆运算+FFT处理和改进后的沿轨迹垂线偏差恢复法，构造了两个区域大小不同、分辨率不同(30'×30'和2'×2')但精度大体相同(10mGal)的重力异常——IGG97和IGG99S。

After much experimentation about "Startup IBM RS/6000 operation system sharing disk in SAN" and "Switch between data center and backup center", based on the research, it design the practicable project of disaster prevention in operation system in the province banks by the method of "cold backup".

简要介绍银行在大集中后省级分行的灾难备份情况，以某省行交易系统为例，从省级分行的灾备需求出发，通过过多次实验，包括"从SAN中的共享磁盘启动小型机"和生产数据中心和备份中心灾难切换，设计了省级行以冷备份方式进行的灾难备份及恢复实施方案，有助于大集中后省级行建立灾难恢复中心的建设，保证银行业务持续性稳定发展。

Beijing 100084, China Abstract: The nephogram signal of FY-2B meteorological satellite is a burst QPSK modulated carrier, and the effect of the special preamble on the carrier recovery loop is analyzed in this paper.

摘 要："风云二号B星"气象卫星的原始云图数据是时分复用的突发载波调制信号，本文就其特殊的预告码对于载波恢复电路捕捉性能的影响进行了分析，并对具有不同类型和带宽的低通滤波器的载波恢复电路性能进行了仿真。

On the basis of pollen analysis of surface sample in North China, polynomial function analysis method was applied to establish pollen climate response surface of Pinus, Betula, Quercus, Artemisia, Chenopodiaceae, Compositae, Picea, Ephedra, Gramineae in North China, therefore an easy and applicable method for reconstructing palaeoclimate and palaeoenvironment with data of fossil pollen was founded; Multi-analysis method was applied to analyse the principal elements of surface sample pollen in central Inner Mongolia Steppe, the assemblages of surface sample pollen in steppe area and its relationship with vegetation type were discussed with helps from spore-pollen analysis of a peat section in Chasuqi, Inner Mongolia and 〓C chronometer, fossil pollen data were obtained with high resolution on the peat section in Chasuqi. Vegetation succession and environmental changes since Holocene at resolution of 70 years were primarily reconstructed in south Mount Daqingshan and Plain Tumete. The changes in the area were copmared with those in the neighbouring areas during the same period. It was found that Holocene environmental change had undergone the following stages: cold-arid, temperate-wet, warm-wet, temperate-arid and cold-arid, and the climatical optimum period occurred in 5000-4100 aB.

本文在对中国北方表土花粉研究的基础上，采用多项式函数回归方法建造了中国北方松属、桦属、栎属、蒿属、藜科、菊科、云杉属、麻黄属、禾本科等的花粉——气候趋势面，从而为利用化石花粉资料直接恢复古气候、古环境提供了一种方便易行的方法；采用多元分析方法对内蒙古中部草原区表土花粉进行了主成分分析，探讨了草原区表土花粉组合的规律及与植被类型的关系；本文还应用孢粉分析方法，结合〓C测年技术，通过内蒙古中部察素齐泥炭剖面高分辨率的化石花粉数据，初步恢复了大青山山地南部及土默特平原地区分辨率为70年的全新世以来植被演替和环境变迁的状况，并与邻近地区的全新世古气候、古环境进行了对比研究，研究发现，本区域全新世古环境的变迁序列基本上可以与周围地区及华北地区进行对比，其环境变迁经历了凉干～温湿～暖湿～温干～凉干的变化，且气候最适宜期出现在5000～4100aB.P。

Several representative regions including humid subalpine area, arid valley and the adjacent recovery area and the plateau region of Minjiang riverhead were selected to study the soil nutrient and biodiversity change. Based on field vegetation investigation, soil sampling and analyses, Ecological effects of land use/cover in these regions were discussed. Also in corporation with the social and economic data, the recovery methods of different degraded region were put forward.

研究选取亚高山湿润区域，半干旱河谷区及其恢复区，岷江源头高原面区域作为重点，通过大量的野外植被调查，土壤采样分析，多元统计方法等研究典型区土地利用／覆被变化的生态效应；并根据社会经济资料和调查数据和土地覆被-土壤相互作用规律，提出了岷江上游生态恢复对策。

Jobs were run simultaneously, unless you had data spooling turnedon and the spool file held the full contents of both jobs. In other

在同一次恢复中 Bacula 不能恢复两个不同的 job ，如果这些 job 是同时运行的，除非你已经打开的数据缓冲缓冲文件有两个 job 的全部内容。

Depending on the selected wiping method your data is unrecoverable using software or hardware recovery techniques.

依靠该安全清除手段，你的数据在使用软件或者硬件恢复技术的情况下不可恢复。

Regeneration may also be used to recover data from an unrecoverable media error.

重构也用于从不可恢复介质故障中恢复数据。

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。
