ABSTRACT Gated 〓Tc〓-hexakis-2-methoxy-isobutyl isonitrile /〓F-fluorodeoxyglucose single photon emission tomography with dual isotope simultaneous acquisition can provide the information about left ventricular function, myocardial perfusion and metabolism simultaneously.

Tc〓-甲氧基异丁基异腈和〓F-脱氧葡萄糖双核素同时采集单光子计算机断层显像可以一次显像获得左心室心肌的血流灌注和葡萄糖代谢的情况，如果加上门控采集，可以同时了解左心室功能的信息。

The STM image is shown the surface structure of the single atomic height step for miscut angle of 0.5°,and the surface structure of the double atomic height step for miscut angle of 4.5°.

观察到错切角为0.5°时STM像为单原子高度台阶表面结构，错切角为4.5°时STM像为双原子高度台阶结构。

The thickness of the inner wall was (0.68±0.46) mm. It showed no significant difference between the two sides of the optic canal in diameters(P＞0.05).(2)The optic canal, the superior orbital fissure and the inferior orbital fissure were respectively shown as track, crack and gorge type in CT axial pictures, while in the coronal pictures, they were respectively shown as butterfly eyes, horizontal fissure and vertical fissure type.(3)The relationship of the posterior ethmoid sinus and the optic canal was: anterocanal(42.00%), semicanal(27.5%), whole-canal(18.75%),sella turcica(9.75%) and circumcanal(2.00%).(4)The relationship of the position of the sphenoidal sinus and the optic canal was:Ι degree sphenoidal sinus(20%),Π degree (63%) and Ш degree (17%).

双侧间差异均无显著性（P＞0.05）；②视神经管、眶上裂、眶下裂在CT轴位像上分别表现为&轨道状&、&裂隙状&和&狭谷状&，在冠状位像上分别表现为&蝶眼状&、水平状裂隙和垂直状裂隙；③后组筛窦与视神经管的位置关系为：管前型占42.00%、半管型占27.50%、全管型占18.75%、蝶鞍型占9.75%和管周型占2.00%；④蝶窦气化度与视神经管的位置关系为：Ι度蝶窦占20%、Π度蝶窦占63%和Ш度蝶窦占17%；⑤视神经管内侧壁骨质缺损发生率为25.5%，缺损平均长度为(5.07±2.52)mm。

Owsley assumed a guarding position in the doorway of Tom's room--half sitting, half lying in a sphinxlike pose with his paws out in front of him.

奥斯利在汤姆房间的门口摆着一种护卫的姿势--半坐半躺，双爪伸在前面，就像埃及狮身人面像的那种姿势。

All at once the angry squirrel expression of the princess's lovely little face changed to an attractive look of terror that awakened sympathy. She glanced from under her brows with lovely eyes at her husband, and her face wore the timorous, deprecating look of a dog when it faintly but rapidly wags its tail in penitence.

公爵夫人那副魅人的、令人怜悯的、畏惧的表情替代了她那漂亮脸盘上像松鼠似的忿忿不平的表情；她蹙起额角，用一双秀丽的眼睛望了望丈夫，俨像一只疾速而乏力地摇摆着下垂的尾巴的狗，脸上现出了胆怯的、表露心曲的神态。

Your two breasts are like two fawns, twins of a gazelle, that feed among the lilies.

5你的双乳像一对羚羊，像孪生的小鹿在百合花中吃草。

I am for an art that joggles like everyones knees, when the bus traverses an excavation.

我追求一种艺术，它抽起来像一支烟，闻起来像一双鞋。

Aberration Decoupling Analysis in Adaptive Optics System with Two Sets of Wavefront Correctors for All-path Aberration Correction.

双波前校正器全光路像差校正自适应光学系统像差解耦分析。

Critics such as Elizabeth Whelan, of the American Council on Science and Health, a consumer-education group in New York (Whelan says that about a third of its two-million-dollar annual budget comes from industry), think that the case against BPA and phthalates has more in common with those against cyclamates and Alar than with the one against lead.

据伊丽莎白·魏兰说，纽约的消费教育组织美国科学与健康委员会（American Council on Science and Health）两百万的年度预算中有三分之一来自企业。委员会中像魏兰这样的批评家认为，反对使用双酚A和酞酸盐更像反对使用甜蜜素和艾拉，而与反对铅不同。

To meet the demand of the 60 nm spatial resolution,the zone plate imaging technology must be employed.

在X射线成像光束线光学系统的设计基础上，对光束线的能量分辨率和光子通量进行了计算，并对双晶单色器第一块晶体的热载影响进行了模拟分析，同时利用波带片成像技术对实验站进行了设计，达到了60 nm的空间分辨率。

It has been put forward that there exists single Ball point and double Ball points on the symmetrical connecting-rod curves of equilateral mechanisms.

从鲍尔点的形成原理出发，分析对称连杆曲线上鲍尔点的产生条件，提出等边机构的对称连杆曲线上有单鲍尔点和双鲍尔点。
