A panticular NO microelectrode has been developed,possessing good selectivity, sensitivity, and mechanical strength, and a novel test technique of NO microelectrode has been established. Neurotransmitters including monoamines, amino acids, peptides, and related bioactive substances such as calcium, magnesium, kalium, natrium and indole substances in brain have been studied by capillary electrophoresis with electrochemical detection. Some problems in analysis of actual samples have been solved, such as micro sample injection and the joint of CE-ED with micro-dialysis.

On the other hand,it can be found thatthe oxidation state is sample dependent by studying the high wavenumber(～1100cm-1)vibration of Si-O-Si in detail.

另一方面，样品制备时的光照水平明显影响不同样品中的氧化层的组织状态。

Total RNA was isolated from phloem of young shoots and retro-transcripted to cDNA by RT-PCR with specific primers, and the amplified cDNA fragments were sequenced for identification of subtypes. An effective RT-PCR technique was established for detecting citrus viroid types, and three types were recognized, i.e.

以田间柑橘枝条韧皮部为试材，提取总RNA，反转录成cDNA，再用不同类型类病毒的特异引物进行PCR扩增，鉴定出各个样品所携带的柑橘类病毒类型；通过测序分析各类型的序列，并与国内外报道的序列进行同源性分析，确定所测样品的亚型。

In the chapter 4, the HPLC analyses of Uridine and Thymidine implanted by ions with high energy are done. The result shows that the dose effect curves of ions with high energy are almost the same to the dose effect curve of ions with low energy. At the beginning, the damage of implanted ions to the sample is large, with the dose increasing, the damage drops sharply.

第四章对高能离子辐照尿苷和胸苷做了HPLC分析，结果表明高能离子辐照胸苷和尿苷样品的剂量效应曲线和低能离子基本相同，都是在注入初始阶段对样品的损伤比较大，随着剂量的增大，损伤迅速减小。

The study of N+and Ar+ implanted into Uridine with different depths shows that Ar+ can damage the sample more greatly at the beginning. Because the energy loss of Ar+ at each length unit is much greater than N+.

氮、氩离子注入不同厚度的尿苷样品实验表明，在注入初始阶段，氩离子更能造成样品的损伤，这主要是因为氩离子在单位距离上的能损比较大。

Whereas the two types of mechanism ofconduction at higher temperature, are considered the nearest-neighbor hoppingBa_(1-yLa_ySnO(3-δ)and as the excitation of elec trons to the conduction bandBaSn_(1-xSb_xO_3-δ...

而在较高温度区域，BaSn＿（1－x）Sb＿xO＿（3－δ）样品的电导主要是电子从定域态到扩展态的跃迁所贡献，Ba＿（1－y）La＿ySnO＿（3－δ）样品的电导则可能来源于电子的最近邻跳跃。

At high temperature, the carriers of low energy band thermalize and the carriers of high energy band dominate the luminescence.

Ga〓In〓P喇曼模表现为双模形式：类GaP的LO〓模（无序样品在383cm〓，有序样品在381cm〓）和在360cm〓处类InP的LO〓模。

Microstructure-evolution of the silicon nitride ceramics sample during sintering process was investigated by a synchrotron radiation X-ray computed tomography technique. The projection images of the sample were obtained during the sintering process in real-time. 2-D and 3-D reconstructed images were obtained by treating the projection images of different sintering periods with filter back projection arithmetic and digital image processing methods.
