Process:① the platinum wire dipped in concentrated hydrochloric acid to colorless colorless flame on the ignition;②sample in the colorless flame ignition, to observe the flame color (if test potassium cobalt glass through observation, because in most cases need to be used when the system of potassium sodium, potassium solution, therefore often contain sodium, and sodium yellow flame color reaction, a small amount of yellow and purple, respectively, can not come out).

3操作过程：①将铂丝蘸浓盐酸在无色火焰上灼烧至无色；②蘸取试样在无色火焰上灼烧，观察火焰颜色(若检验钾要透过钴玻璃观察，因为大多数情况下制钾时需要用到钠，因此钾离子溶液中常含有钠离子，而钠的焰色反应为黄色，黄色与少量的紫色无法分别出来)。

The optimization of extract condition, the component and the pH of mobile phase and the selection of electrode potential were taken into account in the two methods.

Naphthalenesulfonic acid, 3-hydroxy-4-[(1-hydroxy-2-naphthalenyl)azo]-, monosodium salt;3-hydroxy-4-(1-hydroxy-2-naphthalenylazo-1-naphthalenesulfonic aci monos;3-hydroxy-4-[(1-hydroxy-2-naphthalenyl)azo]-1-naphthalenesulfonic aci monos;alizarine blue black ocbn;alizarine blue black ocgn;alizarine blue black ocgp;alizarine blue ocb;azochromol blue black eb

性状描述：棕黑色粉末。溶于丙酮，不溶于甲苯，醇溶液为樱桃红色。水溶液热时为紫黑色，加盐酸后初为红棕色，而后沉淀呈棕黑色；加氢氧化钠为深蓝色，而后为樱桃红。硫酸溶液为深蓝色，用水稀释析出紫黑色沉淀。

Since the decreases of meperidine content were found to be similar for both types of ampules, the stability of meperidine is not correlated with ampule type.

然而贮於两种安瓿之降解反应变化程度经评估并无显著差异，此结果显示盐酸配西汀注射液在两种安瓿中的安定性无显著差异。

The objet of the present research is to assess the decomposition of Meperidine HC1 in sealed injection packaged in colorless or in amber ampules. Accelerated tests as well as storage tests were executed at 40℃, 60℃ and 80℃ for both ampule types.

基於此，本研究将盐酸配西汀注射液充塡至无色与琥珀色透明安瓿中，熔封后进行40℃，60℃，80℃加速试验与储存试验，以评估其在两种不同安瓿中的安定性情形。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
