在旧房改造时通常要对旧墙面进行铲除抛光，目前普遍使用角磨机进行人工打磨，其劳动强度大，打磨后的墙面不平整。本文设计出了一种墙面抛光机器人，它可全自动的实现对旧房墙面的打磨抛光，以机器的有序抛光代替人工的无序抛光，改善了劳动环境，防止了环境污染，并可大幅度提高效率，减轻人工劳动强度。

In the Embolic Protection in Patients with Atrial Fibrillation trial, researchers compared the current standard of therapy, anticoagulation with warfarin, to a fabric-covered expandable nitinol cage known as the WATCHMAN, which blocks blood clots that typically form in the left atrial appendage, an outpouching of the left atrium.

在房颤患者的血栓保护试验中，研究者比较了目前应用华法林抗凝的治疗，以及一种名为WATCHMAN的左心耳封闭系统（可防止左心耳内血栓的可膨胀镍钛装置）的治疗效果。

In river crossing of long distance pipelines,hard materials such as mortared block stones and concrete are often used in traditional construction process for restoring riverbank.

长输管道穿越河流后，针对河流岸堤的恢复，传统施工工艺多采用浆砌块石或混凝土等硬质材料，与原河道堤岸不和谐，破坏了自然河流的生物链，而生态型护岸既可防止水土流失，又可满足生态环境要求，是管道施工大开挖穿越河流后堤岸恢复的好方法。

Blanch Coke Law: Flower is the woody branches will end on the candle flame, burning 2-3 minutes later, charred squid剪去point Add alcohol immersed one minute, out on the water after rinsing in clean inserted after bottle, flowers in hand to avoid the translocation organizations plug, prevent shear branches I was bacterial infection, has been continuously making flower water supply, extended preservation.

灼焦法：是将木本花卉的枝条末端放在蜡烛的火焰上烧2-3分钟后将烧焦的花枝剪去一点放入酒精中浸泡1分钟，取出后放在清水中漂洗干净后插入瓶中，这样既可避免花枝的输导组织堵塞，又可防止枝条剪口被细菌感染，使花朵不断得到水分供应，延长保鲜。

The mechanical leveling system can realize accurate leveling of the platform by servo-motors and drive system, braking by motor brake (worm and worm wheel system features self-locking) to permanently lock the support system after leveling. Bellows outside outriggers functions sealing and dust-proof of the screw rod; guiding slide blocks are used to prevent screw rod from rotating; displacement sensors installed inside drive system deliver real-time information to determine platform height; load cells deliver data of loading conditions of every outriggers in balancing.

平台机械调平系统通过伺服电机、传动系统可实现对平台的精确调平，并通过电机制动器制动（蜗轮蜗杆系统也具有自锁特性），对调平后的支撑系统进行长期锁定；支腿外部的波纹管可实现丝杠的密封防尘；支腿上部的导向滑块可防止丝杠自转；支撑驱动系统内部安装的位移传感器随时传递信息确定台面的高度；荷重传感器为平衡各支腿的受力状态传输数据。

In the joint of LG PEX-A Pipe ,male xocket is pressed to a convex on the inserting part and the fastening ring will contract to fasten up the heating pipe by the fastening of outer nut,and there is also a convex on the ring to offer close coupling by mechanical re-press effect to prevent water from leaking in case of heat expansion.

在LG地热管中的连接部位不仅阀门管套插入部分的凸起部位被机械作用压密，而且随着外部螺母被拧紧，使紧固环收缩，从而带紧热炕暖气管，另外由于存在凸起部位，可通过机械作用进行再次压密，因此可防止由于热膨胀而引起漏水。

Explanation: It is good for the outdoor sport and leisure activities. 3Layer fabric: surface layer with TEFLON is flexible and anti-greasy dirt; mid-layer is waterproof, windproof and moisture permeability; lining use fleece to keep warm and ventilate. The lining seam is sewed by mesh that reduces friction, and it is benefit in sport. An elastic rope is on the bottom. The pocket is on the chest with special technology which is waterproof. Side pocket uses mesh that can reduce the cloth weight

产品说明：此款适合户外运动或休闲；采用复合面料制成，表层面料四面具有弹性，结合立体剪裁，方便运动，Teflon处理更可防止油污渗入，有效保持表面清洁；中间的薄膜具有优异的防水防风及透湿性能；内里采用具有小突起效果的绒布设计，保暖舒适的同时确保透湿性，使人体始终感觉到舒适；内里缝份特用经编布包缝，减少磨擦，利于运动；下摆装有可戴手套单手调节的弹力绳；热贴合技术将口袋平压于前胸部位，不易撕裂且可阻止雨水进入；侧袋布采用网眼，拉开即可透气，同时减轻了服装的重量。

So that the channel immediately exit valve seat to prevent the rapid expansion of body wall and the wall suffered cavitation damage, and for Water in the needle valve, the expansion chamber diameter of 1.5 times the diameter of including pull back the export channel, including length of 8 times the diameter when subjected to cavitation can be avoided.

使紧接阀座出口端的通道急剧扩大可防止阀体壁和管壁遭受气蚀损坏，对用于水厂中的针形阀，其扩大腔室的直径为管径的1.5倍，包括出口退拔在内的通道长度为管径的8倍时，可避免遭受气蚀。

In the negative and interrogative forms, of course, this is identical to the non-emphatic forms.

。但是，在否定句或疑问句里，这种带有"do"的方法表达的效果却没有什么强调的意思。
