In order not to break existing code , this definition could be enforced by the compiler only when a class is explicitly tagged as immutable as follows 为了不打破现有代码，这个定义可以使用编译器加强，即只有一个类被显式标为不变时，此类才是不变类。
In chapter 3 , we devote ourselves to investigating the similar problems for a class of linear and nonlinear integro - differential equations with infinite and time - dependent delays 第三章，我们对一类具无限时滞及变时滞的线性及非线性积分微分方程系统考虑了类似问题。
( 4 ) when the gas cloud radius and the barrier interspaced ratio are given , the explosion overpressure increases with the growing of barrier number 气云半径和障碍物空隙率不变时，随着障碍物数量增大，爆炸超压逐渐增大；障碍物数量相同时，障碍物半径越大，爆炸超压越大。
The principal database in a mirroring session can also act as the primary database in a log shipping configuration , or vice versa , as the log shipping backup share is intact 当日志传送备份共享保持不变时，镜像会话中的主体数据库也可以担当日志传送配置中的主数据库，反之亦然。
Results show when velocity of flow remains unchanged in the onflow area and openness of the tube is changed , then resistance coefficient changes obviously 实验结果表明：在湍流区域内流速（量）不变时，改变管件开度，阻力系数变化较显著；改变流量，管件开度不变时，变化不大。
When the width of the channel is unchangeable , the more are the numbers of the channels , the narrower the channel becomes , the evener the oxygen on the surface of diffusion layer becomes 当流道宽度不变时，流道数目越多，流道间隔越窄，越有利于氧气在扩散层表面上的均匀化分布。
The main results are as follows : l . when the proportion of interfacial thickness and sic particle size is fixed , the particle size has no effect on thermal conductivity of composite 主要结论为： 1当界面层的厚度和颗粒尺寸之比固定不变时，颗粒本身的大小对复合材料的热导率没有影响。
The connecting force between pipe coupling and connected pipe is resulted from the shape memory alloy ' s recovery stresses during its transformation to parent phase when the alloy is heated with constrains 形状记忆合金管接头对被接管的抱紧力源于形状记忆合金升温相变时，在约束下产生的回复力。
On the other hand , certain amount of ar is benefit for the basal plane orientation , which is similar to what observed in mwecr cvd ~ & bn ~ i , the deposition of al 一定量的ar有利于产生基面平行衬底的取向，这与其他沉积al的实验一致。气体对取向的影响可能与物理轰击作用和相变时的过饱和度均有关系。
If the host pulls clock low before the first high - to - low clock transition , or after the falling edge of the last clock pulse , the keyboard / mouse does not need to retransmit any data 如果在第一个高- >低时钟跳变时， （或者在最后一个时钟脉冲的下降沿之后）主机将时钟拉低，键盘/鼠标不必重新传输任何数据。
