The transition is safe , reversible , and incredibly easy , and unlike a conversion to xfs , jfs , or reiserfs , you don t need to back up and recreate your filesystems from scratch 转换是安全的、可逆的、并且令人难以置信地简单，和到xfs 、 jfs或reiserfs的转换不同，您不必备份和从头创建文件系统。
In this paper , because direct current coefficients of 8 8 block have been predicted with integer dpcm , each steps of transform in dct and dpcm were made up of the reversible integer transform 由于本文对块间直流系数进行了整数dpcm预测，因此dct 、 dpcm的每一步均由可逆的整数变换构成，保证了图像的无损恢复。
Apparent suspension viscosities and shear stress can increase several orders of magnitude . the kaolinite - organic matter intercalation compound is a new material with properties both of kaolinite and organic matter 当对它施加电场时，其粘度、剪切强度瞬间变化几个数量级，表现出固体的性质，具有快速可逆的特点。
Conclusions emotionak stress can precipitate severe ? reversibke keft ventricukar dysfunction in patients without coronary disease . exaggerated sympathetic stimukation is probabky centrak to the cause of this syndrome 结论情感应激可导致无冠心病的病人发生严重的、可逆的左心室功能障碍。对于该综合征的发生原因，夸张的交感神经刺激可能十分重要。
Purpose : the recently described posterior reversible encephalopathy syndrome ( pres ) classically consists of reversible vasogenic edema in the posterior circulation territories , although conversion to irreversible cytotoxic edema has been described 目的：近来提出的后部可逆性脑病综合征（ pres ）主要包括后循环区域可逆的血管性水肿及不可逆的细胞毒性水肿。

Next , this thesis presents a data lineage tracing approach , wivem ( weak inversion and verification of attribute mapping ) , which can calculate ( attribute - level ) derivation set of attribute mapping 作者根据可逆与弱可逆的思想，提出了一种“基于属性映射的弱逆与验证的方法( wivem ， weakinversionandverificationofattributemapping ) ”求解属性映射的(属性级)起源集。
Also , by the means of the pattern of matrix and the pattern of linear operator , we characterize the linear operators that strongly preserve nilpotence and that strongly preserve invertibility over antinegative commutative semirings without zero divisors 另外,利用矩阵模式和算子模式等工具，我们在非负无零因子半环上刻画了强保持幂零的线性算子和强保持可逆的线性算子
