查询词典 enamel paper

First firing of raw materials are usually basic glaze frit, in the process of production need to add metal oxides, metal ions is also a special color of the enamel glaze color, or as a gel, or suspension-like particles of the dispersion or absorption of light and color, for example, cobalt oxide blue or purple, blue green copper oxide, cobalt oxide copper oxide mixture is significant blue, red cuprous oxide, nickel oxide in the potassium content of the glaze was red, in the sodium yellow glaze of green, if used alone was brown iron oxide, cobalt oxide and manganese dioxide are combined black or dark brown.

通常是先将原料烧成基本釉的熔块，在制作的过程中再加入需要的金属氧化物，也就是以金属离子特具的颜色而使珐琅釉呈色，或成为胶状，或悬浮状的粒子对光线的色散或吸收而呈色，例如氧化钴呈蓝或紫色、氧化铜呈蓝绿色、氧化铜混和氧化钴则显青色、氧化亚铜呈红色、氧化镍在含钾之釉中呈红色、在含钠之釉中呈黄绿色，又如氧化铁单独使用呈褐色，与氧化钴及二氧化锰合用则呈黑色或黑褐色。

Methods:The enamel surfaces of the lased groups were irradiated by pulsed Nd:YAG laser at five levels:1 W 20Hz,1W 15Hz,1.5W 20Hz,1.5W 15Hz,2W 15Hz.

分别用 1W、2 0Hz，1W、15Hz，1.5W、2 0Hz，1.5W、15Hz，2W、15Hz共 5个能量输出组照射离体牙釉质表面，测定其与复合树脂的抗张粘结强度，并与未处理组、35 %磷酸酸蚀组进行对照。

The decorative design incorporated on this cloisonné enamel dish, specifically the use of lotus flowers with large leaves extending in homogeneous directions, is typical of mid-eighteenth century wares.

Agricultural Research Service entomologist Tom Sappington works in the ARS Corn Insects and Crop Genetics Research Unit at Ames, Iowa. He has tracked local weevil movements by marking the insects with enamel paint or fluorescent powders and recapturing them later. Now he uses "microsatellites"-short, repetitive DNA sequences-and population assignment tests to find out where weevils in different populations have come from.

美国农业部网8月23日消息，美国农业研究局的昆虫学家汤姆在艾奥瓦州的埃姆斯玉米虫害作物和遗传学研究组，一直以来用瓷漆或萤光粉来跟踪当地棉铃虫的踪迹，现在他们通过&微型卫星&-短的重复序列DNA和繁殖分配试验，来定位寻找棉铃虫的行踪，这些测试有助于确定那些迁徙来的不同种类的棉铃虫到底从何而来。

However, enamel and enameloid are significantly different in development, and dentin shows many histological variations; hence their evolution has been intensively studied. Nevertheless, their genetic basis has been revealed only in tetrapods.

这两类动物的釉质和釉质瘤发育是截然不同的，牙本质发育在组织学上差异也较大，关于这两类动物进化方面的研究很多，但涉及遗传基础的研究仅限于四脚动物。

Among these traits is the tooth, which consists of two characteristic mineralized tissues, a highly mineralized surface layer (enamel in tetrapods and enameloid in fish) and a softer body, both supported by basal bone.

牙齿的变化便是其中之一，牙齿由两种典型的矿化组织组成：即高度矿化的表层（四脚动物的釉质和鱼类的釉质瘤结构）和相对较软的牙本质，下方的基骨起支持作用。
