reflection n. 1.【物,計】反射;反射波[光,熱,音,色]。 2.反映;反影,映像,(映在水等中的)影像;〔比喻〕學人樣的人,極像…的人,逼肖的形象[言語、動作、思想]。 3.反省,熟慮,沉思,回顧;〔pl.〕感想,意見;【心理學】(神經(jīng)等的)反射作用。 4.非難,譴責;丟臉,恥辱 (on, upon)。 5.折轉(zhuǎn);彈回;【解剖學】翻轉(zhuǎn)(處),折轉(zhuǎn)(處)。 theory of reflection 反映論。 an angle of reflection 反射角。 He is simply a reflection of his father.他完全是他父親的復本。 I have a few reflections to offer on what you have said. 我對你的發(fā)言提供幾點意見。 be lost in reflection 沉思。 cast a reflection on 譴責…,成為…的恥辱。 on [upon] reflection 仔細想,反?。粚Α焕?,使…名譽受影響,使…蒙受恥辱;中傷,影射(On reflection, I doubt whether I was right. 細細想起來我倒懷疑我講的是否正確了)。 without (due) reflection 不經(jīng)思考,輕率。 adj. -al
The reflection point will, generally, not lie vertically below the observation point . 一般情況下,反射點并不在觀測點的正下方。
The reflection points for the transformed waves do not coincide with those of the non-transformed waves . 轉(zhuǎn)換波的反射點與非轉(zhuǎn)換波的反射點不一致。
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 共反射面疊加利用了鄰近多個共反射點道集的相似性,提高了資料的覆蓋次數(shù),從而壓制了隨機噪聲,增強反射波同相軸的連續(xù)性,大幅提高了地震資料的信噪比。
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 在三維三分量地震勘探資料處理中,對于反射縱波資料可以采用常規(guī)方法進行處理;而對于反射轉(zhuǎn)換波資料,由于其傳播路徑的非對稱性,轉(zhuǎn)換波共中心道集不再是共反射點道集,轉(zhuǎn)換波時距方程也不是雙曲方程,因此不能采用常規(guī)縱波處理方法來處理轉(zhuǎn)換波資料。
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標地質(zhì)體的數(shù)字模型,根據(jù)射線追蹤正演分析,目標地質(zhì)體的參數(shù)分析(面元分析等) ,統(tǒng)計求取復雜地質(zhì)模型目標層真正的共反射點覆蓋次數(shù),比較cmp面元與實際crp面元的覆蓋次數(shù)差異, cmp道集對應的共反射點面元分析,針對覆蓋次數(shù)較低的目標層面元調(diào)整和優(yōu)化觀測參數(shù),提高目標層的采集質(zhì)量和勘探效果。
