First, it discusses the impact of the number of dimensions on rating results and the four meta-dimensions in AC. Second, it introduces the indexes of rating accuracy in AC and expounds different types of rater training programs and their impact on rating accuracy. Third, although AC has proved good criterion-related validity, the research on its construct validity has not yet reached an agreement.

The results showed that: different concentrations of sucrose and boric acid had significant impact on pollen germination, but different concentrations of calcium had no significant impact on pollen germination. It was most appropriate for tube elongation when sugar 150 gL^(-1) and boric acid 100 gL^(-1). Lack of sucrose would lead to the accumulation of callose in top of pollen tube and hold back its growth. The distribution of callose was regular in pollen tube when the medium lacked boric.
结果表明:蔗糖、硼酸浓度间对花粉萌发有显著影响,钙浓度间对花粉萌发的促进作用不明显;蔗糖150 gL^(-1)、硼酸100 mgL^(-1)时最适宜花粉管伸长;蔗糖的缺乏会导致胼胝质在花粉管顶端积累,使其生长停滞,缺硼时胼胝质在花粉管内分布正常。

In order to testify our whether correction to Rossi's exchange term andthe potential of electron and nucleus is reasonable, we calculate 〓 moleculeelastic differential scattering cross section by electron impact on 100eV, ourresult is obviously better than Rossi's. Then we calculate elastic differentialscattering cross section at 150eV. In order to check the program thatcalculates molecule excitation cross section by electron impact, we calculatehydrogen excitation cross section from ground state to 〓 state at 20eVand 30eV, oxygen excitation cross section from ground state to 〓 state at15eV and 20eV. These calculations are in agreement with other theoreticresults, and experiment measure. Finally, we calculate sulfur moleculeexcitation〓 cross section by electron impact at5eV,7eV,9eV, 11eV, 13eV,15eV, and draw curve of excitation total crosssection corresponding to incident electron energy.
为了核对我们修改的计算激发态的程序是否正确,计算了电子与氢分子碰撞从基态激发到〓态入射能量分别为20eV和30eV时的微分截面以及电子与氧分子碰撞从基态激发到〓态入射能量分别为15eV和20eV时的微分截面,与别人的理论计算结果、实验的测量值基本一致,最后计算了电子与硫分子在5eV、7eV、9eV、11eV、13eV、15eV时的碰撞激发〓截面,作出了电子的入射能量与激发总截面的关系曲线,找出了总截面最大时对应的电子入射能量大约是11电子伏。
