Methods of test for petroleum and its products - petroleum products - transparent and opaque liquids - determination of kinematic viscosity and calculation of dynamic viscosity 石油及其产品的试验方法.石油产品.透明和不透明液体.运动粘度的测定和动力粘度的计算
The mucus you vomited may be the secretion from the oral cavity or pharynx . however , if the mucus tastes sour or bitter , it may be secretion from the stomach due to reflux 黏性的透明液体，可能是口腔或咽喉的分泌，但如果黏液带酸或苦味，则可能是胃液倒流。
A colorless , odorless , clear liquid noncombustible , thermostable , very stable to various chenicals , having good lubricity & excellent dielectric properties , nonpoisonous & noncorrosive 无色无臭透明液体，不燃烧，对热稳定，对各种化学品高度稳定，具有良好的润滑性和优良的介电性，无毒，无腐蚀性。
Product description - pyrrolidone is colorless or yellowish clear liquid , has tiny ammoniacal odour ; is a strong polar organic solvent , can dissolve each other with water and general organic solvent by any proportion 物理特性：在室温下呈无色或浅黄色透明液体，有轻微的气味，溶于水及各种有机溶剂，极易水解和聚合。
After three to four days the blisters will burst and release a clear fluid , and become small erosions . if they are not being infected , about ten days , the erosion will automatically healed leaving a scab 大概在三至四日，水泡会自动破裂，流出透明液体，跟著变成小溃疡，如果没有受细菌感染，大概十天左右，伤口会自动收乾痊愈。
A distant field interference of non - single - core light beams is analysed in a transparent liquid or solid when the bubble is irradiated with laser , a formula on optical path length difference is derived , interference regions and causes of interference rings thick inside and thin outside are analysed , the diameter of bubble can be measured by method of interference , the size of bubble and refraction index of gas inside the bubble can be measured in the depths of medium 摘要对透明液体、固体中气泡在激光照射下产生的一种非单心光束干涉进行了远场分析，得到了程差公式，分析了干涉的区域、圆环状干涉条纹内密外疏的原因，通过干涉的方法可以测量气泡的直径，能够用于介质深处气泡尺寸及泡内气体折射率的测量。
