Results L* in pat of opaque and body become decrease and a*,b* become increase generally with the increase of each group of color guide stage,then a*、b* of incisor translucent and cervical increase tendency unapparently.

结果 随着A、B、C、D各组比色板色阶的增大，不透明瓷、牙本质瓷的L*值呈递减趋势，a*、b*值呈递增趋势，但是颈部瓷、透明瓷的a*、b*值的递增趋势变化不明显。

Results: Ceramometal restorations were stronger than nature tooth; the ceramometal restorations with venner type frame designs were stronger than full-bake type frame designs.

结果：金瓷冠比天然牙有更大的抗压强度；镶嵌型支架设计的金瓷比全瓷型支架设计的金瓷冠有更大的抗压强度。

Methods Simulated the process of firing and repolishing when fabricate porcelain fused to metal restoration in clinic, then observed the microstructures of alloys by Field Emission Scanning Electron Microscopy and X -ray energy spectrometer.

烤瓷熔附金属修复体，又称金属烤瓷修复体，是先用合金制成金属基底，再在其表面覆盖与天然牙相似的低熔瓷粉，在真空高温烤瓷炉中烧结熔附而成的，因兼具金属的强度和韧性以及陶瓷的美观和逼真，是目前口腔冠桥修复中应用最广、最受欢迎的一种临床修复体。

The differences between the two groups of glass powder were: b value and chroma of the No. 3 core ceramic were lower than that of AL3 core ceramic, while a value was higher; b value and chroma of the No.

不同的是No.3铝瓷的b值和饱和度较AL3铝瓷低，a值较高；No.1和No.2铝瓷的b值和饱和度较AL1和AL2铝瓷偏低。

Methods Separately adopted porcelain- biscuit coronal with traditional metal margin and non- noblemetal, and with Jiantai porcelain margin and non- noble metal to restore the damaged teeth, and defective teeth, thenobserved whether the color of the gingival margin changed or not, checked the intensity of the tooth margin restored.

分别采用传统金瓷边缘非贵金属烤瓷冠和肩台瓷边缘非贵金属烤瓷冠两种方法修复牙体、牙列缺损，随访观察牙龈缘变色现象有无，检查修复体边缘密合度。

The purpose of this study was to evaluate the shear bond strength between porcelain and electroformed copings after different surface treatments, with comparison of Ni-Cr alloys, to explore the bonding mechanism through observing the electroformed coping surface and interface of metal-ceramic by SEM and EDS analysis. It will provide the basis for clinical application. PartⅠEffects of different surface treatments on bond strength of porcelain fused to eleetroformed copings Materials and Methods: Forty-five cylindrical Ni-Cr alloys were made, and gold copings were deposited on them and divided into 5 groups randomly.

本实验拟测量金沉积基底几种不同表面处理后的金瓷剪切强度，并与Ni-Cr合金进行比较；通过对不同表面处理后的金沉积基底、金瓷界面进行扫描电镜观察和能谱分析，探讨不同表面处理对金沉积金瓷结合的影响，为金沉积烤瓷修复体的临床应用提供参考依据。

2Titanium cobalt the metal alloy roast porcelain hat, gold leaf metal alloy to roast porcelain hat and gold deposition to roast a porcelain hat:Match to be called precious metal to roast a porcelain hat, inside the hat for the titanium cobalt metal alloy, gold leaf metal alloy and 99.99%ly electroplate pure gold respectively, they all belong to sloth metal and cause several rates of allergy smaller, and the physics and chemistry function is settled.

钛钴合金烤瓷冠、金铂合金烤瓷冠以及金沉积烤瓷冠：合称为贵金属烤瓷冠，内冠分别为钛钴合金、金铂合金、99.99%的电镀纯金，它们均属于惰性金属，导致过敏的几率较小，理化性能很稳定。

For blue and white porcelain, this paper analyzes the black fleck on the surface of an imperial blue and white porcelain sherd in Xuande Period, Ming Dynasty by using plane-scan analysis method with SRXRF; and the paper makes "relatively age-judging analysis" for sherds of Qing Dynasty with PIXE.

在汝瓷的产地分析中，本文采用EDXRF探针，测试了清凉寺出土的古汝瓷和若干钧瓷、现代仿汝瓷等瓷釉和瓷胎的常量元素及微量元素，并利用多元统计中的因子分析方法，处理测试所得的成分数据。
