The comparison of IR spectrum and X-ray diffraction and waxy crystal size for paraffin, gum ,and asphaltene before and after treatment was made.

用降凝降粘剂EVA+AA处理高蜡原油，并对原油处理前后的石蜡、胶质、沥青质进行红外特征吸收峰、X射线衍射峰以及蜡晶尺寸变化研究。

It not only can destroy the wax crystal congeries . but also can prompt their formation .

低速剪切既可能使蜡晶聚集体破碎，从而恶化加剂原油的低温流动性，也可能促进蜡晶的聚集。

The treatment can be detected by characteristic spectral features, but it is not always possible to establish whether the starting material was amber or copal.

在欧洲琥珀和蜜蜡通称为amber。这是学术上的对蜜蜡的正确的最严谨的定义。

The crystallizability and solution properties of polyacrylate depressants and their depressive effects on two waxy oils were studied. It was found that the crystallizability of PA depended on the length of its side chain and molecular weight. Gel was observed in the concentrated solution, The temperature of gelation, which was a measure of the crystallizability of PA in solution, was higher for the PA itself with stronger crystallizability.

对聚丙烯酸长链酯的结晶能力和溶液性质及其对两种含蜡油的降凝效果进行了研究，发现PA的结晶能力取决于PA侧链长度和相对分子质量，而其在溶液中形成冻胶或沉淀的温度（反映PA在溶液中的结晶能力）与PA本体的结晶能力有关，而PA对含蜡油的降凝效果则与PA在油中的结晶能力有关。

Result: The density values measured by two methods investigated above were significantly different ( P .01), the density values of Pyritum, Haematitum, calcined Pyritum and calcined Haematitum measured by direct densimetry were increased 1.66%, 9.43%, 96.72% and 9.02%, respectively compared with that measured by sealing wax densimetry.

结果：直接密度测定法与封蜡密度测定法测得的自然铜生品、赭石生品、煅自然铜、煅赭石的密度有显著的差异( P 。01)，直接密度测定法比封蜡密度测定法测得的自然铜生品、赭石生品、煅自然铜、煅赭石的密度平均增加1.66%，9.43%，96.72%，9.02%。

Dental floss:a waxed or un waxed thread used to remove food particles and plaque from the teeth.

洁齿线：一种上蜡或未上蜡的用于去除牙齿上的食物残碴和牙斑的线。

Sequences analysis revealsthat these 54 strains have as high as a 99% similarity in 16S rRNA gene level. Allthese 54 strains could be classified into six subgroups according to six differentregions on full-length 16S rRNA gene. Even if the regional differences are not evidentto distinguish B. thuringiensis from B. cereus, however the data of the 16S rRNA genesequences will serve to broaden the database for Bacillus, and provide someinformation for the classification of genus of Bacillus. Additionally, seven B.

本研究利用通用引物，对54株苏云金芽胞杆菌和蜡状芽胞杆菌的16S rRNA基因进行测序，并对所得到的序列进行简单的分析，发现苏云金芽胞杆菌和蜡状芽胞杆菌的16S rRNA基因的相似性很大，大约为99％，在其全长含有6个区域的不同，根据这6个区域将Bt和Bc分成6个亚群，而Bt和Bc在不同亚群之间交替存在，说明16S rRNA基因上的差异不足以区分Bt和Bc。

Electrotype: A duplicate relief printing plate made electrolytically by depositing copper on a wax mould taken from an original plate or type and backing it with a lead alloy.

电铸版：是一种复制凸版式。先用蜡在原身版式或字版上套出铸模，把铜用电解法沉积于蜡铸上，然后用铅合金衬背而成。

Encaustic painting was the ancient method of fixing pigments with heated wax.

蜡画是一种古老的画法，它将颜料与加热的蜡混合。

This paper presented particularly the colony-counting method of Bacillus cereus in gold deposit of Shewu Mountain in Jiayu county, Hubei province. Many factors affecting counting results, such as colony morphology and positive bacteria category on mannitol-yelk-polymoxin agar medium, centrifugation and dilution in sample dealing process were analysed in detail, and an improved enumerative method was acquired.

本文详细叙述了湖北省嘉鱼县蛇屋山金矿区土壤中蜡样芽孢杆菌的菌落计数方法，对甘露醇—卵黄—多粘菌素琼脂培养基上菌落的特征和MYP培养基上反应呈阳性的细菌种类、土样处理过程、计数方法等影响土壤中蜡样芽孢杆菌的菌落计数的因素进行了详细的分析，从方法学方面做了改进。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
