查询词典 orientation reversing

The Izanagi sub-plate, the most active one of paleo-Pacific plate, subduction into east Asian with NW orientation during Jurassic, resulted in the NW compression and shortening of continental China and its adjacent areas in a whole, most areas of south China then suffered from contraction, inducing a series of small-scale intermountain basins; whereas for the eastern segment of Nanling, including most areas of western Fujian, southern Jiangxi and northern Guangdong, the stress was of extensional regime, resulted in the formation of rifting basins.

进入侏罗纪以来，作用最强的古太平洋板块中的伊佐奈歧板块朝北西方向运移、俯冲到东亚大陆之下，使中国大陆及邻区受到较强的总体上向北西的挤压和缩短作用，华南大部分地区处于挤压环境，形成一系列小型山间盆地；而在南岭东段闽西、赣南、粤北一带产生拉张背景，形成裂谷盆地。

Yoree Koh, 25, arrived at La Guardia on Wednesday to find her American flight to Chicago had been canceled, meaning she will miss an orientation at Northwestern University.

25岁的优瑞*科尔于星期三抵达拉厄尔迪亚机场，却发现她到芝加哥的航班被取消了。那就意味着她将错过在西北大学的一个适应期。

To visualize the effects of Lorentz violation, it is useful to think of spacetime as having an intrinsic orientation.

要将劳仑兹违逆的效应具象化，把时空想成是具有内禀方向的会有帮助。

The real orientations of specimens were detemined by the Laue back-reflection method,The results indicated that the tensile strength and the stress rupture life at the temperature 700℃ were affected strongly by the orientation, however there appears no considerable effect on those properties at 950℃.

用背反射劳埃法测定了试样拉伸轴偏离柱晶凝固方向〈100〉的真实偏角。结果表明，在700℃，瞬拉强度及持久寿命有明显取向关系。在偏角20°之内，上述性能急剧下降；而在950℃，尚未发现明显取向关系。上述取向关系用Schmid规律和交滑移强化机理得到合理解释。

Microscopic characteristics of cladded crystal fiber are analyzed by X-ray diffraction, Laue X-ray diffraction and scanning electron microscopy, it is found that magnesium-ion indiffusion does not affect the single crystal structure and the domain structure of the magnesium diffused crystal fiber. It is found for the first time that MgO-rich layer in the magnesium diffused LiNbO〓 surface layer exhibits the crystal structure of an unknown compound from the Li-Mg-Nb-O ternary system and MgNb〓O〓. It is proposed for the first time that this unknown compound and MgNb〓O〓 in MgO-rich layer are the real sources of magnesium-ion indiffusion LiNbO〓. Their appearance indicate that MgNb〓O〓 is in the surface layer of MgO-rich layer, the unknown compound is in the subsurface layer and beneath where the MgNb〓O〓 is located, and these compounds have obviously preferred orientation.

通过镁离子内扩散法，首次在国内实现了具有阶跃和抛物折射率分布的c轴LiNbO〓单晶光纤和a轴Nd：MgO：LiNbO〓单晶光纤的芯—包层波导结构，为我国在该项目的研究填补了空白；建立了晶纤损耗的测量系统，提出了利用单模石英光纤作为晶纤入射光耦合器的思想；通过对晶纤损耗的测量，得到了包层晶纤比未包层晶纤损耗降低约14倍的好结果，并实现了低次模传输：对经镁离子内扩散实现包层后的晶纤的微观特性，利用X射线衍射，劳厄照相和扫描电镜表征发现，晶纤并不因镁离子的内扩散而影响其单晶结构和镁的扩散层畴的变化。

The α-BaB〓O〓 crystal is colorless, transparent and without cracking. The cracking problem has been overcome by a special growth procedure. The dislocation density, crystallization morphology and growth habit of α-BaB〓O〓 crystal have been systematically studied by chemical etching method, X-ray laue orientation of synchrotron radiation, double-crystal diffraction topography. The growth striation and irregular dislocation consist of the primary defect in α-BaB〓O〓 crystal. The convex solid-liquid interface is stable during the whole growth process.

在国际上首次采用提拉法生长出φ50×40mm〓的α-BaB〓O〓晶体，生长方向为[0001]，晶体完整、无色透明；提出了三种固相反应的原料制备方法，并保证B〓O〓过量1mol%；采用独特的生长装置和程序有效地解决了α-BaB〓O〓晶体易开裂的问题；首先采用化学腐蚀法、白光X射线衍射术、X射线双晶衍射形貌术等研究了α-BaB〓O〓晶体的位错密度；首次采用同步辐射X射线劳埃定向术研究了α-BaB〓O〓晶体的结晶形态及生长习性；结果发现α-BaB〓O〓晶体的缺陷以位错为主，部分α-BaB〓O〓晶体中存在生长条纹。

Through comparing with the results by simulation to study the effects of theprojectile"s final velocity, the angle of rotation and the ballistic trajectory"s migration withdifferent projectile"s rotating speeds, different target"s moving speeds and differentpenetration angles.

通过比较数值模拟的结果来研究不同弹头转速、目标速度、侵彻角对侵彻过程中弹头最终速度、翻转角度和弹道偏移的影响。
