VVA

This thesis mainly focuses in VVA technology which runs through every step of simulation model procedure.

讨论了贯穿于仿真建模每一步当中的VVA技术方法.

In the end, the control strategy of VVA was applied in a 4V cylinder head and experimental results proved its good adaptability.

最后，将可变气门控制策略应用于4V发动机缸盖，试验结果表明，可变气门控制策略具有良好的适应性。

One common purpose of verification, validation and accreditation ( VVA) and test and evaluation ( TE) is to reduce risks and increase credibility.

校核、验证和确认（VVA）与测试和评估（TE）的目的之一都是为了减少风险，增加可信度。

VVA ( Velocity Variation with Azimuth) is stable but only can identity a large suite of reservoir and has inaccurate resolution for identifying thin reservoir.

速度随方位角变化法（VVA）比较稳定，但只能识别大套储层，对于识别薄储层的分辨率不够。
