2.The casing wave and formation compressional wave can be differentiated by the waveform difference between open hole and cased hole,and the formation compressional wave can be extracted by a STC(slowness-time coherence) method.
从下套管前后测得的全波波形的差异可区别套管波和地层纵波,采用慢度-时间相关STC(Slowness-Time Coherence)法可提取地层纵波。
3.Methods Thirty cases (35 eyes) diagnosed as AMD patients with classic CNV were treated with PDT. The data of visual acuity testing, fluorescein angiography (FFA), indocyanine green angiography (ICGA) and optic coherence tomography (OCT) were used to evaluate the effects of a single treatment of PDT before and 1 week, 1 ,3 month after treatment. Results The visual acuity of 34 eyes were stable or improved in 3 months follow up;
方法 回顾分析经荧光素眼底血管造影 (fundus fluorescein angiography,FFA)、吲哚青绿血管造影 (indocyanine green angiography,ICGA)和光相干断层成像术 (optic coherence tomography,OCT)等检查确诊的 30例渗出型 AMD患者的 35只患眼行 PDT治疗前和治疗后 1周 ,1、3个月的临床资料 ,以视力、FFA、ICGA和 OCT检查结果为观察指标 ,评价 PDT对渗出型 AMD的短期治疗效果。
4.Objective To observe the characteristics of the images of optical coherence tomography(OCT) performed on the patients with uncompletely posterior vitreous detachment (PVD) Methods 81 patients(86eyes) with uncompletely PVD were underwent routine ophthalmic examination. B-scan ultrasonography and OCT examination.
目的分析玻璃体不全后脱离的光学相干断层扫描(optical coherence tomography,OCT)图像特征,探讨玻璃体不全后脱离与所引发的玻璃体视网膜病变的关系。 方法对81例(86只眼)玻璃体不全后脱离患者进行眼科常规检查、B型超声检查和OCT检查,并对所获得的OCT图像进行分析,观察玻璃体视网膜界面的异常图像特征。
5.The same spot of CNV formation was determined by fundus fluorescein angiography(FFA) and optical coherence tomography(OCT) on the 7,14,21 and 28 d after laser photocoagulation. The changes of the number /area ratio of fluorescein leakage(mm2) at the early-phase(<2 minutes) and the late-phase(>10 minutes) of each day were measured.
分别于光凝后7、14、21和28 d随机选取5只行眼底荧光素血管造影术(fundus fluorescein angiogrphy,FFA)和光学相干断层成像术(optical coherence tomography,OCT)检查,比较FFA早期(<2 min)和晚期(>10 min)荧光渗漏斑数/平均渗漏面积(mm2)的变化,并行统计学分析。
6.Its basic principle is that in the 3 D seismic data volume after offset the coherence values of every sample point in every channel with its surrounding dats are found,thus,the 3 D data volume which indicates the coherence of seismic data (coherence cube for short)is obtained.
其基本原理是，在偏移后的三维地震数据体中，通过对每一道每一个样点求得与其周围数据的相干性值，来获得一个表示地震数据相干性的三维数据体（简称相干体）。
7.In this paper coherence chart method is popularized to typical multispin weakly coupling systems such as AMX, AX_2 and AX_3.Applied examples for DEPT experiment, homonu-clear and hetronuclear relay coherence experiment are given.
本文将此方法推广至AMX、AX_2和AX_3等典型多自旋弱耦合系统,并以DEPT实验及同核和异核Relay相干实验为例作了说明.
8.When Δ δ =| δ -2- δ -1|=0 and %q% and %ξ% remain unchanged, the non|classical coherence degree is decreased with the increase of Kerr effect, and the value of Δ δ has an importance influence on the non|classical coherence degree.
当Δδ =|δ2 -δ1|≠ 0且q和 ξ的取值一定时 ,随介质常量x的增大 ,光场两模间的非经典相关程度减弱 ,且Δδ的大小对这种非经典相关程度的减弱有重要影响 .
9.In this thesis the author puts forward the new concept of Xingduanyilian (formal breaking off to highlight coherence) as a technique in writing and translation: when a sentence, particularly a long sentence, is broken into two parts by insertion of a word or phrase, the coherence therein is not weakened in the least but, enhanced instead.
本文作者提出“形断意连”这一概念 :“形断意连”是一种遣词运语之情形 ,指在语言形式上由于插入成分而出现所谓“断开”之时 ,其内在意蕴却前后勾连、一以贯之 ,文章之气势不仅未曾因外在之断开而减弱 ,反倒往往有所增强。
10.[Objective] To investigate the difference of central corneal thickness(CCT) measured by optical coherence tomography(OCT), anterior chamber-optical coherence tomography(AC-OCT),and compare their repeatability.
