Before preparation, the volume of GCF and the amount of AST and ALP were regarded as the baseline. The amount of AST and ALP were detected by automated chemical analyzer, and analyzed the variation between the pre-restoration and post-restoration.

结果： 1。镍铬合金组PFM修复后一个月其临床指标、GCF量、GCF中AST和ALP的总量与修复前相比未出现显著性差异，而修复后三个月其临床指标、GCF量、GCF中AST和ALP的总量与修复前相比有显著性差异。

Each of them had 3 anterior maxillary teeth restored by porcelain-fused-to-nichrome crowns, without other metal fillings or protheses.

对象：选择2006-01/12在河北北方学院附属第一医院口腔修复科就诊的60例上颌前牙有3颗行镍铬合金烤瓷冠修复的患者为实验组，男28例，女32例，平均40岁，均无其他金属充填物和修复体者。

Preheating system of the die set of swaying tray is heated by adopting Cr20Ni80 resistance wire, as diameter d is 1.5mm, node-pitch D is 36mm, screw-pitch h is 4mm, spiral column L' is 0.91m, 220V single-phase contacting is adopted.

摇盘模具预热系统采用Cr20Ni80 镍铬合金材料电阻丝加热，直径d 为1.5mm，节经D 选用36mm，螺距h 选用4mm，螺旋柱长度L'为0.91m，采用220V 单相接法。

The sample's metal surface expanded and the thickness of oxide film is 1.72 times of the control samples.

摘要］ 目的：分析烤瓷用镍铬合金在上瓷前经过阳极钝化，除气预氧化处理后对其表面氧化膜的形貌、厚度的影响。

Methods A total of 56 patients (172 teeth) were randomly divided into two groups: in the experimental group, 30 patients of 86 teeth were restored with IPS Empress 2 all porcelain crown restoration; and in the control group, 26 patients of 86 teeth were restored with nichrome baked ceramic crown.

目的 评价IPS Empress 2全瓷冠修复技术修复上颌前牙的临床效果。方法将56例患者172颗牙分成两组，试验组30例86颗牙，以IPS Empress 2全瓷冠修复技术修复；对照组26例86颗牙，以镍铬合金烤瓷冠修复。

The control group wear ordinary nichrome porcelain - crowns.

目的：探讨镀金镍铬合金烤瓷冠的优越性能。

A novel inlaid super-thin microcrystalline cellulose modified carbon paste film electrode was fabricated by direct inlaying microcrystalline cellulose modified carbon paste film on the surface of nichrome substrate.

以镍铬合金为基体，在其表面通过直接嵌入微晶纤维素修饰的碳糊膜，构建了嵌入式超薄微晶纤维素／碳糊电极。
