The optimal reconstruction windows of patients with stable HR(≤75 bpm and≥91 bpm) were concentrated in 71%,ranged from 65%-80%, and in 41%,ranged from 32%—50%,respectively.The prospectively ECG-gated DSCT coronary angiography can be used in patients with stable HR(≤75 bpm and≥91 bpm) in abstract.②To explore the clinical application of prospectively ECG-gated transverse DSCT coronary angiography.Methods Two hundreds patients[Body mass index:23-25 kg/m~2,122 patients(average HR≤75 bpm),78 patients(average HR≥91 bpm)]with suspected or known coronary artery disease underwent prospectively ECG-gated transverse DSCT coronary angiography,among them,30 patients underwent selectively coronary angiography,grouping them into 2 groups according to the average HR of scanning.Group A(17 cases,HR≤75 bpm),group B(13 cases, HR≥91 bpm),the DSCTA results were compared with SCAG.Then,calculate the accuracy of patients in each group and evaluate the agreement of accuracy between DSCTCA and SCAG by Kappa statistics.

It is usually said that Schnabel's American spirit is embodied in the fact that he is as good as Andy Warhol at marketing himself, making use of mass media strategies. A good example are his movies which turned out to be a huge success.

尽管按照通常的说法，"施纳贝尔的美国精神体现在他与安迪·沃霍尔一样很会利用大众传媒为自己造势推销"，他导演的电影也取得了巨大的成功。

1 Self-threading or sheet metal screws may be used if threads are not stripped when the screw is tightened with a torque of 3.39 N·m (30 lb·in) and if the part or the assembly supported by the screw withstands for 1 min a force equal to four times the mass of the part or assembly, applied in a direction coincident with the axis of the screw.

测试方法：用3.39N.m（30lb.in）的扭力扭紧螺丝，并在装配表面的螺丝轴向施加于四倍于装配物重量，螺蚊应不受破坏。本文由tinson2008在安规网发表，如果提示附件不存在，点我进入备份站下载！

The two species parted evolutionary company only around 5 million years ago, but unfortunately, at just a tenth the body mass of the short-faced bear, the spectacled bear is unlikely to be a particularly good surrogate.

这两种熊在进化过程中，大约是在500万年前从同一个祖先分化出来，但不幸的是，眼镜熊的体积仅为短面熊的十分之一，因此它并不是一个理想的代孕妈妈。

MASS DEFECTIONS. At a press conference tied to the International Radio Exposition in Berlin, the normally good-natured Ricke displayed a touch of testiness toward his critics, saying their ideas about how he should be running the company "don't fit together at all."

在柏林国际无线电博览会的新闻发布会上，平时性情温和的Ricke 在回应舆论对他管理方面的质疑时，情绪异常激动，声称评论中提出的公司管理方面的建议"完全不切实际"。

Undernutrition may be due to a failure of food supply or intake, to deliberate fasting, or to disease and is characterised by weight loss and changes in body composition, which include loss of body fat, loss of lean mass (proportionately greater in disease compared to starvation alone) and a relative increase in extracellular fluid volume.

营养不良可能是由于食品供应或摄入失败，审议禁食，或疾病，是由减肥和身体组成，其中包括身体脂肪，精益质量损失变化的特点（在疾病的比例更比饥饿单）和在细胞外液量相对增加。

As there lack a long-time forming course as in western countries, a solid foundation, and the cultural cultivation of the mass, I am worried that such a kind of liveliness and prosperity will not be necessarily able to develop healthily and persistently. Lots of my good friends are the backbones of "Star Art Exhibitions" and "85 Fine Arts New Tide Movement". When they woke up from their ridiculous nightmares, they vented themselves in various manners, and the manner they used most was to mock. They mocked what they hated acridly. The other manners were anger, mourning, puzzling and sadness.

它没有一个像西方漫长的形成过程，没有坚实的基础，更没有对受众的文化培养，因此我担忧这种热闹、繁荣未必能健康持久地发展，我有许多好朋友都是星星美展、八五新潮里的骨干，当他们从荒诞的噩梦里醒来时，便以多种样式去发泄自我，其中最多的是嘲弄，对憎恶的东西进行刻薄的嘲弄，再就是愤怒、痛惜、迷茫、感伤。

Inflammation per se may be responsible for mild airflow limitation.7 8 9 Indeed, it has been suggested that inflammation may lead to functional bronchiolar constriction by releasing mediators that may act directly on bronchiolar smooth muscle.10 The chronicity of inflammation would, in turn, produce other changes such as airways fibrosis, and may increase the smooth muscle mass either directly as a result of inflammation or indirectly as a result of chronically increased muscle tone.

炎症本身导致了气流限速轻微下降。而事实上它提示了由于释放的介质直接作用于细支气管平滑肌上，炎症引起了功能性细支气管的缢痕。慢性炎症反多来又会产生气道纤维化等其他改变，这样无论是炎症反应的直接影响结果，还是慢性肌紧张增高的直接影响结果，都会增加平滑肌质量。

Preparation of the cathode includes:shaping under the press of 40Mpa, sintering at 550℃for 1 hour and at 900℃for 8 hours and threading with molybdenum bar; Considering the literatures we choose CaCl2 as salt for preparation titanium. Pretreatment of salt is for 1 hour at 100℃and for 2 hours at 300℃. Partial pressure of oxygen which need lower than 5.11×10-7Pa to reduct titanium oxides and hygroscopic property of salt need a sealed equipment to electrolyse. And finally successfully designed a satisfied one and the results show that the equipment can be satisfied the requirment of the experiment. Flow of the inert gas is 1.5L/min, the voltage is 2.8 V, temperature is 850℃and time is 2 hours during pre-electrolysis. Flow of the inert gas is 0.2L/min, the voltage is 3.1 V, temperature is 900℃and time changes with the mass of TiO2 during electrolysis, namely the greater need the longer time; To eliminate influence of salt and other impurities, the products need to wash with distilled water and dilute chlorhydric acid , then wash with dilute hydrochloric acid under supersonic wave assistant. Finally, electrometical properties of the electrolysis of TiO2 is researched by cyclic voltammetry and chronoamperometry, and results show that there are two main reodox steps, namely from TiO2 to TiO and from TiO to Ti.

阴极制备主要包括40MPa压力下模压成型、两段式烧结(1小时内升至550℃保温1小时，再1小时升温至900℃保温8小时)及烧结后TiO2块打孔用钼棒串接三个主要环节；实验中选用CaCl2作为电解熔盐，并对其进行预处理(100℃，保温1小时； 300℃，保温2小时)；经热力学计算，还原钛氧化物的氧分压至少要低于5.11×10-7Pa，结合电解过程中所用熔盐CaCl2有极强的吸水性的特点，电解装置应有较高的密封性，自行设计了一套密封性可靠的电解装置，便于实验过程中熔盐预处理和氧分压的控制；通过干燥处理预电解过程中Ar流量大约为1.5L/min、电压为2.8 V、温度为850℃、时间为2小时，电解过程中Ar流量大约为0.2L/min、电压为3.1V、温度为900℃，实验结果表明电解时间与TiO2质量密切相关，质量越大需要电解的时间越长；通过自来水冲洗—稀盐酸浸泡、洗涤—在超声波辅助作用下稀盐酸洗涤，可减少熔盐及其它杂质对电解产物检测结果的影响；最后，通过循环伏安法、计时电流法对电解机理的研究，确定电解还原TiO2制备金属钛主要经历了TiO2-TiO-Ti的过程。
