The results showed that as low temperature became intensified and prolonged, the leaves of pepper seedling presented increased POD activity, decreaseds SOD and CAT activities, increased MDA content and increased plasm-membrane permeability; the critical temperature (15℃/8℃) showed stronger effects on pepper plants than the lower temperature (19℃/12℃); under the lower temperature, the weak light of 90μmolm^(-2)s(-1) could make the POD activity increase much more, but reduce the decrements of the SOD and CAT activities, and the increments of the MDA content and plasm-membrane permeability, and under the critical temperature (15℃/8℃), an opposite situation occurred.

The effect and its mechanism of temperature during grain filling on rice quality were investigated by using 4 eary-indica rice cultivars with different quality and amylose content. The plants at filling stage were transferred into two phytotrons (Model PGV-36, CONVIRON, Canada), which were set two mean daily air temperatures, i.e. 22℃, optimum temperature regime and 32℃, designed as high temperature regime. The differences in quality properties and starch characteristics of rice between two temperature regimes were determined, and effects of temperature at grain-filling stage on starch biosynthesis in developing rice grains were also analyzed.

In the real bake-out process, it suggests that the air excess coefficient of burning should be controlled within 1 in order to avoid electrode being oxidized by high temperature fume; when the temperature is below 700 C, it rises slowly in temperature to bake out thoroughly and uniformly; when above 700 C, it speeds up in heating-up to reduce the electrode oxidation.

In the one half part, according to the strontium nature, thermodynamic calculation of correlative reaction and the principle of the vacuum aluminothermy reduction process, with the laboratory findings of preparation strontium by vacuum aluminothermy reduction compared and analyzed in different parameter conditions, a variety of factors which effect the decomposition rate of SrCO_3 and the percent reduction of strontia are gotten out. The factors include that the decomposition rate of SrCO_3 is influenced by different addition and pressure. They also include that the percent reduction of strontia is influenced by excess coefficient of reducing agent aluminium powder, the particle size of raw material or reducing agent, the pressure of barbecuing, temperature and reduction time. According to those, we can draw the conclusion as follows:(1) Decomposition temperature of SrCO_3 is decreased by adding carbon and alumina in different degree.(2) With quantitative carbon added under the vacuum condition, the decomposition temperature of SrCO_3 is decreased obviously, which can fall 150℃ compared with atmospheric pressure.(3) In keeping 1150℃ of 2.5h, under the 5Pa vacuum condition, the decomposition rate of SrCO_3 nearly keeps in 99% steadily.

在前半部分的真空铝热还原法中，根据锶的性质、相关反应的热力学计算及真空铝热还原法原理，通过对不同参数条件下的真空铝热还原法生产金属锶的实验结果的分析比较，得出了影响SrCO_3的分解率和氧化锶的还原率的种种因素，具体因素包括不同添加剂、不同气压对SrCO_3分解率的影响，还原剂铝粉的过量系数、原料与还原剂的粒度、制团压力、温度和还原时间等对氧化锶还原率的影响，得出具体结论如下：(1)添加碳和Al_2O_3能不同程度的降低SrCO_3的分解温度；(2)真空条件下加入一定量的碳可显著降低SrCO_3的分解温度，比之常压下可降低150℃之多；(3)在1150℃恒温2.5h、真空度达到5Pa的条件下，SrCO_3的分解率几乎保持稳定在99％；(4)氧化锶的还原率随还原剂过量系数的增大而增大，但是趋势越来越小，当过量系数超过25％后，氧化锶的还原率几乎不再增加；(5)氧化锶的还原率随原料与还原剂的粒度的变细而增加；(6)氧化锶的还原率随制团压力的增加而增加，但超过一定值后，氧化锶的还原率反而会下降；(7)氧化锶的还原率随还原温度的升高而增加；(8)氧化锶的还原率随还原时间延长而增加，在本实验条件下，超过2.5h趋于稳定。

And then the effects of compositions on the mechanical performance, characteristic temperatures, thermal expansion and chemical stability of the glass were discussed. Researches on lead borate sealing glasses show that PbO/B2O3 ratio exerts the most important effect on glass network. ZnO is beneficial to stabilize the glass against devitrification . Bi2O3 has little effects on the sealing temperature, while it helps to adjust the thermal expansion coefficient of lead borate glasses in a definitive range. When 0.5～4 mol% GeO2 is introduced, the glass possesses the highest stability and lowest sealing temperature (400 ?C), which is desirable for low-temperature sealing.

通过对含铅的硼酸盐封接玻璃研究得出，PbO/B2O3比是影响玻璃网络最主要的因素；添加ZnO有助于增强玻璃的稳定性，抑制析晶；Bi2O3对高铅系列配方玻璃的封接温度影响不大，但可使铅硼系列玻璃体系的热膨胀系数在一定范围内可调；在高铅系列配方中，引入0.5～4mol%的GeO2可有效地抑制玻璃析晶，降低封接温度；最终获得了两种性能较好的低熔点铅硼酸盐封接玻璃配方，G3封接温度低达400℃，其PbO含量为54mol%左右，BL10玻璃的封接温度为440℃，但其铅含量大大降低，仅为36mol%。
