BACKGROUND: Total knee arthroplasty is associated with considerable postoperative pain, which, if unrelieved, may result in prolonged hospital stay, inability to participate in rehabilitation programs, poor outcomes, and greater use of healthcare resources.

背景：相当多的全膝置换术会产生术后疼痛问题，而如果疼痛未被减轻则会导致住院时间的延长、不能参加康复训练计划、较差的预后和巨大的医疗保健资源的浪费。

The novel vacuum furnace is employed in laboratory study. Compared with atmosphere magnesium carbothermic reduction furnace, this new one has the merits of high automation, easy manipulation and fine safety. Vacuum coking, vacuum carbothermic reduction process and magnesium vapory condensation process can be carried out in a furnace.

小型实验结果证明：还原温度升高，还原时间延长，氧化镁还原率增大，添加适量的氟化物对还原反应有促进作用；还原过程中真空度随时间的变化具有规律性，由此可以判断还原反应进行的速度与程度；真空中煤还原氧化镁的条件是：配料时保证C：MgO=3：1，并加入占总料重10％的氟化钙作为催化剂，尽可能的提高反应温度至1500℃以上，保温30～40分钟。

DSA features included: dilatations of brain venule could be seen and the number of brain veins increased; the circulati...

其DSA影像学主要表现为：全脑小静脉扩张、迂曲、数目明显增多；全脑动静脉循环时间延长；丘纹静脉和大脑内静脉系统显影增粗、扩张，并发生深静脉滞流，呈现出"雪花样"表现；静脉窦内对比剂滞留、显影延迟或残缺不全。结论：DSA全脑血管造影是诊断脑静脉系统血栓的可靠方法。

The results showed that vinegared egg suspension could evidently promote entero kinesis on the mice,markedly increase swimming time of the rats,significantly enhance cell immune function and decrease lipid peroxidation of brain tissue on the mice.

结果表明：醋蛋液能明显促进动物肠的蠕动，明显延长动物的游泳时间，提高细胞免疫功能，降低脑组织的脂质过氧化作用。

In the invention, heat exchanging pipe is washed once by water in every interval. The scale removal flow is provided with big shear stress and strong embedding ability. It can wash gruel sale of the pipe wall down and clean on line so that purposes of maintaining high-efficiency heat conduction of air cooler, prolonging the running period of air cooler and decreasing operation cost, are achieved.

本发明每间隔一段时间，通入水对换热管束冲刷一次，除垢水流的剪切应力大，裹挟能力强，能使管壁上剥落的粥样水垢冲刷掉，起到在线清洗的作用，从而达到维持空冷器高效传热、延长空冷器运行周期、降低运行成本的目的。

The use of plastic introduction systems will cause unusually long washout times.

使用塑料进样系统将使清洗时间明显延长。

No need to cut, drag or weld heavy roofing materials like the existing asphalt-based SBS layer; or long application duration due to long cure time which is typical of water-based coating waterproofer.

不像旧沥青基 SBS 卷材或传统屋面防水材料，需要裁切、拖曳或焊接，也不像水性丙烯酸防水涂料由于干燥时间长，导致工期延长。

The extended development time is essential for rigorous testing, as Waugh explains,'When we put things in space we have to make sure that they'll survive the radiation environment, the extremes of heat and cold.

延长的探测时间对于严格的测试非常重要，正如Waugh解释道：当我们向太空发射探测器时，我们必须确保这些探测器能够经受住辐射环境、酷热和严寒的气候。
