reflection n. 1.【物,计】反射;反射波[光,热,音,色]。 2.反映;反影,映像,(映在水等中的)影像;〔比喻〕学人样的人,极像…的人,逼肖的形象[言语、动作、思想]。 3.反省,熟虑,沉思,回顾;〔pl.〕感想,意见;【心理学】(神经等的)反射作用。 4.非难,谴责;丢脸,耻辱 (on, upon)。 5.折转;弹回;【解剖学】翻转(处),折转(处)。 theory of reflection 反映论。 an angle of reflection 反射角。 He is simply a reflection of his father.他完全是他父亲的复本。 I have a few reflections to offer on what you have said. 我对你的发言提供几点意见。 be lost in reflection 沉思。 cast a reflection on 谴责…,成为…的耻辱。 on [upon] reflection 仔细想,反省;对…不利,使…名誉受影响,使…蒙受耻辱;中伤,影射(On reflection, I doubt whether I was right. 细细想起来我倒怀疑我讲的是否正确了)。 without (due) reflection 不经思考,轻率。 adj. -al
The reflection point will, generally, not lie vertically below the observation point . 一般情况下,反射点并不在观测点的正下方。
The reflection points for the transformed waves do not coincide with those of the non-transformed waves . 转换波的反射点与非转换波的反射点不一致。
Based on the similarity of common reflection point trace gathers in one coherent zone , crs stack can focus more energy on the vicinity of the reflector , and therefore can obtain a high signal - to - noise ratio zero offset section by stacking events with the same phase 共反射面叠加利用了邻近多个共反射点道集的相似性,提高了资料的覆盖次数,从而压制了随机噪声,增强反射波同相轴的连续性,大幅提高了地震资料的信噪比。
For processing of 3d and 3c seismic data , the reflected p - waves can be processed with the conventional methods , while the reflected converted waves can not be processed with the conventional p - wave processing methods , because their travel paths are asymmetrical , their common midpoint gathers are no longer common reflection point gathers , and their time - distance equation is non hyperbolic 在三维三分量地震勘探资料处理中,对于反射纵波资料可以采用常规方法进行处理;而对于反射转换波资料,由于其传播路径的非对称性,转换波共中心道集不再是共反射点道集,转换波时距方程也不是双曲方程,因此不能采用常规纵波处理方法来处理转换波资料。
This paper proposes a method for optimizing the parameters of geometry system . based on the ray tracing for the built - model , discussing and analyzing the parameters of geologic aim such as the bin size , calculating the fold of aim layer ' s common reflection point , comparing the fold of crp with the fold of common mid - point , the geometry system ' s parameters are adjusted to improve the low fold bins , the quality of data collection and effect of exploration 本文提出了首先建立目标地质体的数字模型,根据射线追踪正演分析,目标地质体的参数分析(面元分析等) ,统计求取复杂地质模型目标层真正的共反射点覆盖次数,比较cmp面元与实际crp面元的覆盖次数差异, cmp道集对应的共反射点面元分析,针对覆盖次数较低的目标层面元调整和优化观测参数,提高目标层的采集质量和勘探效果。
