Under 140 mmol/L NO3(superscript -) treatment, putrescine in leaves were significantly lower than control, but the ratio of/Put in both leaves and roots were remarkably higher than control.

叶片中Spm和Spd及根中Spm含量在一定浓度范围内，均随NO3浓度的增加而升高，当NO3浓度高于140 mmoL/L时，其含量反而开始降低；叶片中Put含量均明显低于对照。

Results The average concentration of camphor in indoor air was 1.00mg/L inarchives applying synthetic camphor, 0.74 mg/m3 in archives applying commercialized mycocide (the main compo-nents were synthetic camphor and pyrethrin ), and 0.14 mg/m3, applying natural camphor.

The gel dynamics experiments showed that the gel formation law was similar with the other polymer systems, which wasrelated with dense surface under the soft coagulating condition and the thickening gel; the square of gel thickness was linear with coagulation time. The qualitative analysis of the surface puckers of fibers spun from wet spinning and dry-jet wet spinning was made. The positions where the die swell appeared were not the same and the die swell appeared at the air gap where the fiber would markedly been elongated and vary little in the coagulant, thus the surface of fiber spun from dry-jet wet spinning was more smooth. The radial component concentration gradient was responsible for the radial structure of PAN fiber spun from dry-jet wet spinning. The thicker surface with microvoid structure of

对湿纺和干湿纺进行比较表层沟槽的产生进行定性分析，原因在于孔口胀大区域出现在不同位置，在干湿纺中，溶液的孔口胀大出现在空气层，并在该区完成大部分形变，进入凝固浴后形变很小，纤维表面较为光滑；干湿纺PAN纤维径向结构存在差异，这与丝条内组分由于双扩散进行导致径向上存在浓度差异直接相关；凝固强度较大的体系，可以获得厚度较大且孔结构尺寸较小的皮层；含较少缠结的PAN原液在纤维成形后截面很圆整，但原液缠结浓度增大时成形后圆整度下降；PAN纤维成形是一个远离平衡的过程，凝固作用缓和的体系可以使成形过程靠近平衡，可获得更大尺寸的孔洞结构；原液中少量的非溶剂添加剂显著改变纤维径向结构，可获得孔洞尺寸更小和更为均一的径向结构，这与径向浓度差异的减小、分相时间的集中相关；PAN原液的成形纤维表面依赖于凝固强度；由AFM对相近凝固条件下成形的PAN膜进下

In this research, the activities of CWDE were measured by saccharifying according to the theory that red-brown amino compounds were produced when 3, 5-dinitro salicylic acid and aldehyde were heated together. And the testing conditions were made clear. The activity of Cx should be tested with optimal temperature of 50℃, optimal pH of 4.8, incubation time of 30 min, and optimal substrate of 0.6% CMC-Na. Due to the heat-libality, Cx should be sterilized more than 10 min. The testing conditions of the activity ofβ-G were almost the same with Cx except the substrate of 0.5% salicin and the sterilization time of more than 15 min.

采用膜表面自组装技术，能使DNA探针与膜牢固结合，且分布均匀；探针与靶序列浓度增加均使压电传感器上杂交量增加，但探针浓度过大时反而抑制杂交，靶序列浓度与频率变化之间呈饱和曲线关系。

The cell wall of sclerenchyma in ROL barrier was significantly thickened in conventional lowland rice (Yangdao 6) with the increase of PEG concentration, but upland rice (Zhonghan 3) was not sensitive to low PEG concentration. The thickening of ROL barrier obviously became stronger at 50 g·L-1 and higher concentrations. Besides, suberisation of cell walls increased significantly with the time extension.
