The mechanism of higher alcohol synthesis on Cu-Zn-Mg-K catalysts was monitored by in situ IR chemical trapping technique . The dynamic technique was used to increase the surface concentration and response rate of surface intermediates, thereby to increase their IR signal intensity. Pulse injection of CH3I and CH3OH into the in situ cell resulted in the appearance of some crucial C2 intermediates in the reaction, such as surface acctyl, acetate, ketene and enolate .

The mechanism of higher alcohol synthesis on Cu-Zn-Mg-K catalysts was monitored by in situ IR chemical trapping technique . The dynamic technique was used to increase the surface concentration and response rate of surface intermediates, thereby to increase their IR signal intensity. Pulse injection of CH3I and CH3OH into the in situ cell resulted in the appearance of some crucial C2 intermediates in the reaction, such as surface acctyl, acetate, ketene and enolate . Meanwhile, the pulse in situ technique was used to observe the evolution from primary species to C2 intermediates and the influence of methanol on higher alcohol synthesis. The results indicated that higher alcohol synthesis over Cu-Zn-Mg-K occurred via a classical CO insertion mechanism.

采用原位红外测试技术结合化学捕获方法研究了Cu-Zn-Mg-K催化剂上合成低碳混合醇的反应机理。用动态技术提高表面物的浓度,增强其红外信息和提高它们的响应速度。捕获剂CH_3I和CH_3OH以脉冲方式引入原位红外池,分别捕获到一些较关键的C_2中间物:表面乙酰基、表面乙酸盐、乙烯酮和烯醇盐。利用脉冲-原位红外测试技术,观测了从C_1中间物到C_2中间物演变的动态过程,同时还考察了甲醇对低碳醇合成的影响。指出在Cu-Zn-Mg-K上低碳醇的合成是通过CO插入碳链递增这种反应途径实现的。

For studing the relationship between the immediate early genes( IEGs) and nerve injury, the expressions of c fos mRNA and Fos in rat spinal cord neurons was examined by in situ hybridization using photobiotin avidin gold silver stained c fos cDNA probe and PAP immunohistochemical method during 1h 14d after intraspinal cord injection of kainic acid (KA).

For studing the relationship between the immediate early genes( IEGs) and nerve injury, the expressions of c fos mRNA and Fos in rat spinal cord neurons was examined by in situ hybridization using photobiotin avidin gold silver stained c fos cDNA probe and PAP immunohistochemical method during 1h 14d after intraspinal cord injection of kainic acid (KA). Image analysis showed that the optical densities of these hybridization signals with c fos cDNA probe and Fos IR signals increased significantly in L 1~3 ventral motoneurons of KA treatrment rat, starting from 2 hour after KA injection, reaching to a maximum in 4 and 6 hours, and retured to control level 12 hours post injury. These were followed by a second inerease by 3rd days in ventral motoneurous. However, a dramatic inerease of expresions of c fos mRNA and Fos in dorsal horn neurons were observed during 2 to 6 hours after KA injection .The results indicated that KA is a selective neurotoxin for spinal cord neurons. For motoneurons, second increase of c fos expression was related with neurodegeneration by KA treatment,and was thought to be an early harbinger of neuronal death.

为探讨即早反应基因(immediateearlygenes,IEGs)在神经损伤过程中的变化规律,用原位分子杂交和PAP免疫组织化学方法观察了大鼠脊髓内注射红藻氨酸(kainicacid,KA)后1h至14d的不同时间点,L1~3脊髓腹、背角神经元中c-fosmRNA和Fos免疫阳性信号的变化。结果表明,KA致脊髓损伤后2~8h脊髓腹角运动神经元中c-fosmRNA的表达和Fos免疫组织化学阳性反应明显增强,12h恢复至正常水平,伤后3d又明显增强;而脊髓背角神经元内仅在伤后2~6h明显增加。提示KA对脊髓神经元的选择性毒性作用;运动神经元c-fos表达的再次增强与KA所致神经元的不可逆变性有关,亦可看作是神经元损伤后死亡的先兆之一。

The direct current component in the interferogram of conventional FTIR spectroscopy is expressed by  ∫ ∞ 0 B(σ) d σ.However,in time resolved FTIR spectroscopy,the direct current component I dc (τ) also depends upon τ,the time which IR signal appears.I dc (τ) is then represented by  ∫ ∞ 0 B(σ,τ) d σ,called as constant in time DC component by us.I dc (τ) is proportional to the signal intensity B(σ).I dc (τ) can not be filtered by any band pass filter.After Fourier transforming,the I dc (τ) converts to a strong peak at 0cm -1 in the IR spectrum.We call it as constant in time zero frequency signal B τ(0).Either I dc or B τ(0) can be used to monitor a variety of experimental conditions,such as the variation of gas pressure,laser intensity,the carbon deposition on the optics,etc.They can also be applied to measure the instrumental response time and the band pass frequency.

在常规的傅里叶变换红外光谱(FTIR)学中,干涉图的直流成分为∫∞0B(σ)dσ,而在时间分辨FTIR中,直流成分Idc(τ)成为∫∞0B(σ,τ)dσ,即与信号出现的时间τ有关,称为定时直流成分。Idc(τ)具有随红外信号强度B(σ)成正比以及不可被滤除等性质。Idc(τ)经傅氏变换后在光谱中出现定时零频信号Bτ(0)。Idc和Bτ(0)可用来多方面监测实验条件如气压、激光强度和窗口碳化的变化,以及可用于测量仪器的响应时间和带通频率。
