旋回

Methods Thirty inner ears of 15 volunteers were scanned by using a circular temporal coil and three-dimension fast spin echo sequence with a 1^5T GE-signal MRI scanner.

选用15名健康志愿者，使用GE signal1.5T超导型核磁共振机，环行耳颞部线圈，三维快速自旋回波序列(3D FSE T2W1)及脂肪抑制技术，对两侧耳部同时进行扫描。

All these results show that the method could provide a new clew for the quantitative division of sedimentary cycles.

这也为沉积旋回的定量划分提供了一种新的思路。

Every fluctuation period of the earlier 4 cycles covered 0.75 to 1 Ma beingsimilar to that of the fourth-order glacial-eustasy with the interval of 0.1 to 1 Ma, imagining there probablyoccurred 4 fourth-order eustasies during the latest Ordovician from the D. complexus Zone to N. ojsuensisZone.

在前4次旋回中，每次波动的周期为0.75～1Ma，与冰川活动引起的Ⅳ级海平面变化周期(0.1～1Ma)相近，以此进一步推断晚奥陶世晚期(从D.complexus带到N.ojsuensis带)发生过4次Ⅳ级海平面变化。

The variation of the microelement Ni, V, Sc, Rb, Ba and Sr was analogous to the change of the Ce anomaly from the Wufeng Formation to the basal Longmaxi Formation at the Goujiaya and Datangkou sections, and 5 cycles, separately corresponding to the lower and upper part of the Dicellograptus complexus Zone, the lower Pacificograptus pacificus Zone, the upper pan of P.pacificus Zone to the Normalograptus ojsuensis Zone, and N.

在苟家垭和大塘口剖面五峰组-龙马溪组底部，Ni，V，Sc，Rb，Sr和Ba等微量元素丰度以及稀土元素Ce异常的变化具有相似的规律性，可划分成5次旋回，分别对应于D.complexus带下部，D.complexus带上部，P.pacificus带下部，P.pacificus带上部至N.ojsuensis带，以及N.persculptus带至P.acuminatus带。

In order to improve the accurate of measurement, the artifacts, such as eddy current, thermal convection, background gradient must be considered both experimentally and methodologically.

我们把多自旋回波和双向梯度场技术相结合，用来抑制这些干扰，并在生物样品的自扩散系数测定中的进行了应用。

Hybrids of carbonate and terrigenous sediments Carbonate with terrigenous sediments are of characteristic from Emsian to Eifelian in stable shallow-sea faciesregion in Longmenshan area, and they can be classified evidently into hybrid Ⅰ and hybrid Ⅱ(Jingbaoshi-type). Type Ⅰ produced in mud shelf setting occupied hundreds of tempestite beds in which bottom cast、 hummocky cross bedding sandstones、 coquina were inter-beddded with shales that beared a great deal of verm traces、 bioturbations、 benthic communities dominative of brachiopods. Type Ⅱ in sand-mud-marl shelf was characterized by high-energy foreshore sandbeach facies and shelly bank facies.

碳酸盐与陆源碎屑混合沉积方面对微相、相特征、旋回样式、沉积机理研究表明，龙门山地区泥盆纪稳定浅海相区Emsian期和Eifelian期混合沉积十分发育，颇具特色，明显可以划分为两种类型：混积Ⅰ型，泥质陆棚背景下发育风暴沉积组构，幕式风暴期产生具丘状层理、底流冲刷构造的钙质砂岩、介壳岩，平息期则形成具大量虫管和生物扰动的深灰色、黄绿色页岩及海百合茎灰岩，腕足动物等大量繁盛；混积Ⅱ型，砂泥灰质陆棚背景下以发育高能前滨沙滩及生物介屑滩为特色，近滨至陆棚的砂泥灰互为混合，三者比例接近，肉眼难以区别确切岩石类型。
