The traditional objective evaluation method ignores person ' s subjective sensations on the sound , so it is not applicable to the research of sound quality . but the general method of evaluation of sound quality which is carried out with people on - line has the limitation of efficiency , cost , time and so forth , so it is necessary to establish objective evaluation method based on subjective sensations 传统的声音的客观评价由于其没有反映人对声音的主观感受,因此不适用于产品的声质量研究,而常用的由人直接去听测的声质量评价方法由于其效率、滞后性等局限性,因此寻求基于主观感觉的客观评价方法成为必要。
How to evaluate the effect of modern technology of reservoir description in exploration and development , this mainly based on whether what we know about reservoir match what it is . ten - year practice of reservoir description indicate : if we want to establish objective 3 - dimension geological model of reservoir , the different reservoir type , the different exploration and development phase , the different data quantity and quality decide what technical route of reservoir description we should apply 现代油藏描述技术在勘探开发中的应用成效关键在于对油藏认识是否符合客观实际,十年来的油藏描述实践表明,要建立符合客观实际的三维油藏地质模型,关键在于不同的油藏类型,不同的勘探开发阶段,不同资料拥有程度和精度,应采用不同的油藏描述技术路线。
