As material, The changes of the contents of chlorophylls, MDA, praline and the activity of SOD of I. pseudacorus L. leaves were studied with different Pb concentration and different treatment time by sand culture. The results showed that the contents of chlorophylls in the leaves of I.

为材料，采用沙培方法，对不同Pb浓度(0、2、4、6、8、10mmol/L)和处理时间(7、14、21、28d)胁迫下植物的叶片叶绿素、丙二醛和脯氨酸含量以及超氧化物歧化酶活性的变化进行了研究。

The content of praline and activities of superoxide dismutase and peroxidase were increased under Cd stress. The increase of proline content and POD was more pronounced in the xiushui 63 under lower level of Cd, however, it was more pronounced in the Xiushui 09 under higher level of Cd.

总体上，脯氨酸含量、超氧化物歧化酶、过氧化物酶活性均呈上升趋势，其中，在较低浓度Cd胁迫下，秀水63叶片中脯氨酸含量、POD活性增加幅度较大，而在较高浓度Cd胁迫下，秀水09的增加幅度较大。

This method could also be applied to prepare praseodymium oxides, however, it was not successful in preparing other light rare earth oxides.

这种方法可以应用到制备氧化镨，但是，无法成功应用到制备其他轻稀土氧化物。

In this paper, we reported the spectroscopic properties of praseodymium ions Pr(superscript 3+ doped transparent oxyfluoride glass ceramic excited with different laser lines, such as 532, 514.5 and 476.5um.

用不同的激发波长532，514.5，476.5nm，研究稀土Pr(上标 3+)掺杂的透明氟氧化物玻璃陶瓷中Pr(上标 3+)在LaF3微晶环境和玻璃环境中的不同的荧光行为。

The surface film formed at higher potentials consisted of oxides of Ni in predomination with some Fe and little Cr, while that formed at lower potentials was composed of oxides of Cr, Ni and Fe. The latter showed much higher resistance to caustic SCC.

这与较高电位下生成严重贫铬的Ni和Fe的氧化膜，而较低电位下生成由Cr、Fe、Ni的氧化物共同组成的表面膜密切相关。

There was a little difference betweenphotosynthesis characteristic of the two varieties,response of Jiamusi to low temperature andpoor light was more sensitive than that of Longjiao No.2 and decreased pronouncedly withdecreasing light.6.EC and MDA of pepper leaves increased under low temperature and poor light,therewere no significant differences between them with decreasing light at 21-23℃/8-10℃,butthey were increased dramatically at 15-20℃/5-6℃.So we can speculate that lowertemperature was the direct reason resulted in cell membrane lipid peroxidation.7.No significant difference of SOD activity was observed under suboptimal temperatureand poor light21-23℃/8-10℃;150μmol·m~(-2·s~(-1),but SOD and POD activity substantiallydeclined with lowering temperature and light as well as treatment time.8.Under suboptimal temperature and lower light,proline accumulated to increaseosmotic regulation capacity and alleviate chilling damage.Soluble carbohydrate of pepper leaves decreased progressively and significantly with decreasing temperature and lightintensity as well as longer treatment time.So we think that synthesis and transport ofphotosynthetic product were inhibited by low temperature and poor light as solublecarbohydrate was important component of photosynthetic product.

两个供试辣椒品种之间的光合特性略有差异，佳木斯对低温弱光的反应比陇椒2号敏感，尤其随光照降低，其光合作用显著降低。6、低温弱光胁迫下，辣椒叶片的相对电导率和丙二醛含量都有不同程度的提高，在偏低温下，随着光照减弱，相对电导率和丙二醛含量差异不显著；在极端低温下，随着光照进一步减弱，相对电导率和丙二醛含量明显提高，随着处理时间延长，同一温度下，随着光照降低，叶片丙二醛含量也显著增加，由此可初步判断，低温是导致细胞膜脂过氧化的直接原因。7、经偏低温较弱光21～23℃／8～10℃、150μmol·m~(-2·s~(-1)处理后，辣椒叶片的超氧化物歧化酶活性变化与对照无显著差异，但随着温度、光强的逐步降低和处理时间的延长，SOD、POD活性显著降低。8、在偏低温较弱光下，辣椒能积累更多的脯氨酸，增强渗透调节，减轻低温冷害。

In summary, the grain boundary effect in the CMR granular composites strongly depends on the second phase propertied and material preparation method. MR can be enhanced at higher temperature range by appropriate choice of the second phase.

由此可见，不同的第二相材料和工艺制备方法对锰氧化物颗粒复合系统的颗粒边界效应有显著的影响，通过选择合适的第二相材料可以提高磁电阻增强效应所发生的温区。
