These defects result from VAR process, which relates to the size of titanium sponge and alloying elements before melting.
这些缺陷都是真空电弧重熔过程的产物，与海绵钛和添加元素的粒度有关。
If you'd prefer to start MongoDB as a daemon process in the background, issue the following command instead: $ sudo mongod --fork --logpath /var/log/mongodb.log --logappend.
如果您想作为后台守护程序启动MongoDB ，发出以下命令： $sudomongod --fork --logpath /var/log/mongodb.log --logappend.
It adopts the var method to get the co-integrated equation, and discusses the dynamic process with the techniques such as VECM, impulse response and variance decomposition.
具体的实证方法是采用VAR方法，在得出协整方程下，再进一步采用误差修正、脉冲响应、方差分解等技术来探讨汇率的动态变化过程。
