灰线

我是参加灰线旅游的。

I was with the Gray Line Tour .

目的研究家兔前牙行非贵金属烤瓷冠修复后牙龈组织及血液中镍铬元素的含量，初步探讨产生牙龈灰线的原因。

Objective Purpose of the study was to investigate the content of Nickel ( Ni ) and Chromium ( Cr ) ion in gingival tissue and blood , and to discuss the reason of gray line in gingival after wearing non-noble Porcelain-Fused-to-Metal crown .

增殖细胞核抗原、bcl-2在灰线牙龈组织中的表达

Expression of Proliferating Cell Nuclear Antigen 、 bcl-2 in Gray Gingival Tissue

结论PCNA表达与灰线牙龈组织炎症反应有关；

Conclusion There were a correlation between the expression of PCNA and inflammation of the gray gingival tissue ;

PCNA、bcl2的表达，不表明灰线牙龈组织有异常增殖。

The expression of PCNA and bcl-2 protein does not indicate that gray gingival tissue had dysplasia change .

使用LBO晶体腔内倍频避免了KTP易出现的灰线问题；

KTP crystal that is easy to produce gray tracks was replaced with LBO for intracavity frequency doubling .

而细灰线即是将其连结在一起的连线。

They are the connections that actually make nature resilient .

牙龈灰线方面差异无统计学意义。

The difference of marginal integrity between these two groups had no statistic significance .

肩台瓷金瓷冠或金沉积烤瓷冠与普通金瓷冠之间边缘变色和牙龈灰线方面有显著统计学差异。

The differences of marginal integrity and marginal discoloration between metal-ceramic crowns with shoulder porcelain and conventional metal-ceramic crowns had high statistic significance .

3例下眼睑恶性肿瘤患者行上睑灰线切开，利用睑板结膜瓣和下睑切口的内外眦部皮肤游离瓣共同重建下眼睑。

Upper-eyelid in other 3 patients of nether-eyelid malignant tumour were carved , rebuilding the nether-eyelid by conjunctival flap and free flap of cutis from inside and outside canthus .

方法对我院门诊诊断严重上睑内翻倒睫病人111例197眼行睑缘灰线切开带蒂轮匝肌瓣充填术；

Methods 111 cases ( 197 eyes ) of patients with severe upper eyelid entropion were treated using the method of palpebralis margin gray line incision and pediculated orbicular muscle grafting at outpatient department in our hospital .

改进修复后55例83颗金属烤瓷冠颈部缺陷减少分别为颜色54.2%，解剖形态51.9，边缘完整性67.4，颈缘灰线71.1%，牙龈状况71.1%。

After the improvement repairs 83 teeth Porcelain fused to metal crowns cervix blemish decrease difference as color match 54.2 % , anatomy appearance 51.9 % , marginal integrity 67.4 % , cervix margin ash line 71.1 % , health of gum 71.1 % .

基于一维熵的图像阈值自动选取提出了直接利用图像灰度信息的灰值线检测与去除算法。

Automatic Choice of Threshold Value of Gray-level Images by Using 1-D Entropy Proposed in this paper is a line removal algorithm directly based on gray-level images .

在页首长方形块底端画一条1px的灰蓝色的线，混合属性中添加阴影效果。

Add a dark blue1px line on the bottom of the header box , apply the Drop shadow effect .

对除尘器产生的积灰、极线放电等故障现象进行了分析，采取了相应的措施。

By analyzing trouble phenomenon on dust accumulation of duster and polar discharge , the appropriate measures are taken .

加枫的颜色白中略带黄、红、中间有灰棕色的矿物线，制成山纹后，纹理清晰、色泽淡雅。

Add in the white color maple slightly yellow , red , grey brown is among the minerals line , made mountain grain , texture clear , colour and lustre and elegant .

通过对渗流作用下贮灰库的数值模拟计算，得出了各种工况下贮灰库浸润线的变化规律。

The change law of phreatic line under different working conditions is obtained by the numerical simulation for ash fields seepage flow .
