松香的

Because of the inflammable nature of both celluloid and acetone, the process is extremely complicated.

这也是赛璐珞框会有一股淡淡松香的原因，因为赛璐珞和丙酮剂两者都是高挥发易燃性原料，使制作手续繁复。

The classification of rosin was based on published laboratory and clinical data.

松香的分类是根据公布的实验室和临床资料。

State on quality of Chinese gum rosin from 1995 through 2002 was investigated in detail.

从各种不同渠道详细调查了1995年至2002年中国脂松香的质量状况。

The optimal technology was got by the mathematical model-""Quadratic Orthogonal Rotable Combination Design"" as follows: PS-10 0.175%, reaction temperature 272℃ and reaction time 4hr.

通过优化设计，得到制备无色松香的适宜的工艺为：温度272℃，时间4hr，用量0.175％。

In fact, the ancient Egyptians used ointments containing frankincense and spikenard and the Chinese too have long used oils and herbs together with acupuncture.

事实上，古埃及人也曾使用含乳香、甘松香的药膏，中国人针灸时也会用香油及草药。

When the reaction temperatures were 303.15, 308.15, 313.15, 318.15, 323.15 and 328.15 K, respectively, the apparent reaction rate constants of abietic acid were 0.0036, 0.0041, 0.0062, 0.0087, 0.011 and 0.0157 min-1, respectively.

松香的氧化反应温度为35， 40和45 ℃时，表观速率常数分别为0.0009， 0.0015和0.0025 min-1 ，表观反应活化能 E a为80.2 kJ/mol。

Lianghe turpentine relative density, refractive index, initial boiling point, distillation range size, optical activity and chemical composition as well as the softening point, acid value, unsaponifiable matter content, ethanol insoluble matter, ash, optical activity and chemical composition and other physical and chemical characteristics of rosin gum were studied.

研究梁河脂松节油的相对密度、折光率、初馏点、馏程体积、旋光度和化学组成以及脂松香的软化点、酸值、不皂化物含量、乙醇不溶物、灰分、旋光度和化学组成等物理和化学特征。

Fourier infrared spectrum was used to differentiate raw lac, bleached las and lac mixed with resin.

利用傅里叶红外光谱分别对紫胶原胶、漂白紫胶、掺有松香的紫胶、接枝共聚紫胶进行了鉴别研究。

In practice the thickness would vary with time and atmospheric conditions, but the surface would only consist of the decomposition products of oxidised rosin.

在实践中，厚度会随时间和大气条件，但其表面只包括了松香的氧化分解产物。

HARRPA carried out a technical review of various methods available to identify when rosin had been oxidised.

HARRPA 进行了确定何时可被氧化松香的各种方法的技术审查。
