为了使~(18)F-FLT在科研及临床上得到广泛应用，本研究利用CTI公司生产的双管~(18)F-FDG合成模块进行~(18)F-FLT的半自动化生产；并探讨三种合成前体在不同温度和浓度下对~(18)F-FLT放化产率的影响。

Through anglicizing the steering column collisions we can get the impact of conditions in different whereabouts of the impact of displacement of columns.

通过在一定的测试条件下得到转向柱管收缩位移时间曲线图和速度时间曲线图以及不同时刻的碰撞仿真的情况。

The third thermal boundary condition equation joined with the degradation rate of interior wall was used to get the contour of interior wall vs. time under the condition of identical heat flux between fluid and solid in axis direction. The numerical simulation results agrees well with that of measurements.

在气流与固壁之间的热流量沿轴向一致的条件下，通过加入降解退移速率的第三类热边界条件方程，求解出不同时间管内壁面轮廓沿轴向变化情况，模拟值与试验结果基本吻合。

Pt-inserted nanotube titanic acid was prepared as follows: H_2PtCl_6 ethanol solution was filled into the titanic acid nanotubes and then annealed in air at 673 K for 3 h.X-ray photoelectron spectroscopy showed that H_2PtCl_6 has been converted to Pt~0 and PtO.The result of electron spin resonance revealed that there are single-electron-trapped oxygen vacancies to be formed in PNTA after heat treatment in air.

通过在真空条件下将氯铂酸的乙醇溶液引入到钛酸纳米管内，再经过热处理制备了镶嵌铂的纳米管钛酸。X射线光电子能谱表明氯铂酸大部分转变成Pt0和PtO，顺磁共振谱表明在PNTA中生成了束缚单电子的氧空位，在紫外-可见扩散漫散射谱谱上表现出对可见光有吸收能力。

Results:①The center of the homogeneous density soft tissue masses (mean CT value was 50HU) were located in the middle and lower tympanum,and the external auditory canal or the pharyngotympanic tube was involved in the earlier period;②the destructed b...

结果：中耳癌的CT特征：①表现为以中、下鼓室为中心的软组织密度灶，密度均匀，CT值50HU左右，外耳道及咽鼓管早期受累；②呈溶骨性骨质破坏，形态不规则，边缘无骨硬化表现，外耳道后壁破坏较前壁严重；③病灶侵入颞叶，形成肿块，灶周脑水肿不明显；④增强扫描见病灶有中度强化。结论：CT能确定中耳癌的存在及精确显示肿瘤累及范围。

Under managed capitalism, big companies offered long-term security in return for unflinching loyalty.

在管理化资本主义框架下，大企业为员工提供长期的工作保证，换来的是员工的忠诚。

Microscopically, these tumors are composed of tubules and variably sized cysts lined by cuboidal and columnar cells with eosinophilic cytoplasm.

显微镜下，这些肿瘤由小管和由含有嗜酸性胞浆的立方和柱状细胞围成的不同大小的囊腔所组成。

The first special techniques was the method of tightening slip knot predisposed on atrial septal via veins. The suture with loop was placed on the atrial septum incision which will be closed during the decannulation. The loop was hitched up by the drawn-string via vein and tied with two or three slip knot after inserting left atrial cannulas.

第一种特殊技术是一种经静脉应用心导管将右房内预置的滑结拉紧的方法，其要点是术中在要闭合的房间隔切口处做缝合并留好线套，穿上牵引线经左锁骨下静脉引出，插左房管后打2或3个滑结，拔管后应用这种特殊技术将滑结拉紧，并拆除牵引线。

The preparation method comprises the following steps in sequence:(1) metric acetonitrile is added into a dual-bottleneck distilling flask that is provided with a refluxing and condensing tube, and simultaneously, long-chain dialkyl methyl tertiary amine and relevant saturated dihalide are added thereof;(2) nitrogen is pumped for 10 to 20 minutes for deoxidizing;(3) a magnetic mixing reaction is carried through for 10 to 15 hours under the condition of 78 to 83 DEG C.

其制备方法依次包括以下步骤：(1)在装有回流冷凝管的二颈蒸流烧瓶中，加入计量的乙腈，同时按一定比例加入二长链烷基甲基叔胺与相应的二卤代烷；(2)通氮气10-20分钟，排除氧气；(3)在78-83℃条件下磁力搅拌反应10～15h。

Endotracheal tube foreign body was impressed logically because patient had mandibular facture with teeth dislodgement.

因为病人有下颔骨骨折及牙齿的脱落，故合理的怀疑X-光片中气管内管真的显示有牙齿的嵌入。

But we don't care about Battlegrounds.

但我们并不在乎沙场中的显露。

Ah! don't mention it, the butcher's shop is a horror.

啊！不用提了。提到肉，真是糟透了。
