And the emeraldine salts (ES2) of polyaniline were prepared by emeraldine base form of polyaniline doped with different acid dopants at room temperature. The structure and morphology of ES1 and ES2 were characterized by Fourier transform infrared spectrometer, Ultraviolet-Visible spectrophotometer and wide angle X-ray diffactometer, respectively.

并藉由傅立叶红外线光谱仪结构之鉴定，四点导电度计体积电阻之测定，黏度法重量平均分子量之量测，元素分析仪元素掺杂比之测定，紫外线-可见光光谱分析仪吸收波长之解析，X-ray绕射分析仪分子形态之分析，低频/高频阻抗分析仪介电行为之探讨，以及同轴量测系统电磁波遮蔽效应等之量测。

METHODS:The content of the total naphthoquinone was counted in L-shikonin ,methanol was used as solvent and the wavelength was set at516nm.

总萘醌的含量以左旋紫草素计，溶剂为甲醇，检测波长为516nm。

However, if the conventional isothermal sooting flame assumption is followed (where the twocolour emissivity ratio is inversely proportional to the pyrometer wavelength ratio), then the calculated volatile flame temperatures will be lower by ~250 K.

不过，如果采用传统等温碳烟火焰的假设（双色辐射率比值与高温计波长比值成反比），挥发物火焰的温度将会降低250K。

Our laboratory has single-wavelength pyrometers, total radiation pyrometers and IR-thermometers. We have also a middle temperature blackbody, a low temperature blackbody, and a few standard lamps.

本实验室拥有单波长辐射高温计，辐射感温器和红外辐射温度计，以及校准用中温黑体炉，低温黑体空腔和标准温度灯等标准辐射源。

Breath, muscle contraction of the buttocks; arch body, as far as possible to hold his head, right leg straight towards the ceiling (peg-leg knee in order to avoid muscle tension).

呼气，收缩臀部肌肉；拱起身体，尽量抬起头来，右腿伸直朝向天花板（膝微屈，以避免肌肉紧张）。

The cost of moving grain food products was unchanged from May, but year over year are up 8%.

粮食产品的运输费用与5月份相比没有变化，但却比去年同期高8％。
