A new method for simultaneous determination of multicomponent with spectrum transform single wavelength spectropotometry is presented.

提出了一种新的单波长法同时测定多组分的光谱变换分光光度法，并以苯甲酸和苯甲醛混合组分为例论证了该方法的可行性。

The results show that myristic acid radical anion of precursor Zn0.78 Al0.2220.22c13h27COO0.81H2O can be almost completely replaced by complex anion [La(TiW11 O39)2]^3- under special controlled reaction conditions.

结果表明，该产物中[La(TiW11O39)2](上标 13-)配阴离子沿其长轴垂直于层板的方向分布于水滑石层板间，产物有规整的层状结构、大的层间距(d003=3.29nm)、良好的结晶度和热稳定性，产物对二甘醇与苯甲酸的酯化反应、二甘醇的脱水环化反应和苯甲醛的氧化反应具有良好的催化性能。

In this paper,ortho nitrobenzaldehyde is prepared with indirect oxo-process for o nitrotoluene .

以邻硝基甲苯为原料，采用间接氧化法制备邻硝基苯甲醛。

The activation of primary nociceptor cells by FA is likely to be mediated, at least in part, through TRPV1 and/or TRPA1 receptors.

本实验进一步证明甲醛激活初级伤害性感受器细胞可能是通过TRPV1受体和/或TRPA1受体参与介导的。

Of 92 acutely dissociated dorsal root ganglion cells recorded by current patch-clamp technique, 34% were discharged by FA application with the mean onset latencies of the first action potential being (367.34+/-32.96) s. All the FA-sensitive cells were identified as nociceptor cells by their distinguishable features of AP including longer duration, existence of a hump on the repolarizing phase, and longer after-hyperpolarization of APs.

运用电流钳记录的92个背根神经节细胞中，大约有34%的中、小细胞对甲醛溶液敏感，产生动作电位的发放，其产生动作电位的潜伏期是(367.34±32.96) s，并且单个动作电位复极化相具有伤害性感受器细胞的特征性，如动作电位间期较长、复极化相有&驼峰&以及较长的后超极化相。

Results The effect of Periocur and FC is similar. 74.6% canals of the cases used Periocur can be obtusion after one week while 68.3% canals of the cases used FC can be obtursion.

结果 Periocur消炎液组74.6%一次封药后即可行根管充填，甲醛甲酚组为68.3%，两组的临床疗效差异无显著性。
