切割

Stent should be soft, with good lateral bending property, and diameter of the stent should be 1.0-2.0 mm longer than the actual stenosis. Implantation technique should be improved. These can reduce extrusion and cutting action of the atheromatous plaque due to balloon dilatation and stent expansion, and prevent plaque defluxion during implantation. Filter protection device is used to filter tissue debris and to prevent microemboli entering cerebral circulation, which can elevate safety of carotid stent implantation.

选择相对柔软的，侧弯性能较好，且直径应比狭窄处实测直径大1.0~ 2.0 mm的支架，提高置入操作技术，可以减轻支架置入过程中球囊扩张及支架膨胀时对粥样斑块的挤压与切割作用，防止斑块脱落，同时使用滤器脑保护装置以过滤较大组织碎片，阻止较大微栓子进入脑循环，提高颈动脉支架置入的安全性。

Chapter two 4-Hydroxybenzoic acid is connected with PEG6000 through defoliant DCC at rooom temperature, then the product is refluxed with chloroacetic acid in acetone to afford PEG-bound phenyloxyacetic acid, which is reacted with thionyl chloride, ammonium thiocyanate and arylamines in turn to give PEG-bound disubstituded thioureas. After the cleavage with sodium methoxide in methanol, the eleven disubstituted thioureas are obtained.

第二章 利用PEG6000作载体，通过脱水剂DCC在室温下将对羟基苯甲酸以酯键连接在PEG6000上，再与氯乙酸在较温和的条件下生成PEG6000支载的芳氧乙酸，然后，依次与亚硫酰氯、硫氰酸铵、芳胺反应，生成PEG6000支载的硫脲，最后用甲醇钠的甲醇溶液切割PEG，得到了十一种1，3-二取代硫脲。

The next incisions will dele deeper, cutting through muscle and bone.

Three types of the small oscillogram could be obtained when different end depolarizer was applied to the incision of the classical oscillogram.

根据切割经典示波图所用的端点试剂不同，将小示波图分为三种类型。

In oscillographic chronopotentiometry to employ Hg working electrode, oscillographic chronopotentiogram formed after classical oscillogram was incised by end depolarizer was called a small oscillogram.

在以汞电极为工作电极的示波计时电位法中，采用端点去极剂切割经典示波计时电位图后形成的小示波计时电位图。

Cutting-carving process, the same intensity laser processing to ensure that the processing line depth

高速切割雕刻过程中，激光加工强度不变，保证了加工深度一致

Methods Female red Duroc pigs were served as experimental animals, and dermal and adipose tissue incised (n=6) or lacked wounds (n=1) were made on each pig's back using roller dermatome. The megascopic observations of wound healing of each pig in 1, 2, 4, and 12 weeks were conducted.

以杜洛克母猪为实验动物，用滚轴取皮刀在同一个体背部制作真皮及脂肪组织切割(n=6)或缺损(n=1)创面，采用自身配对观察比较创伤后1、2、4及12周的大体愈合情况。
