Results showed that the activity of soil poly-phenol oxidases and acid phosphatase, and soil respiration were suppressed by Starane at 0.5 and 5 mgkg^(-1) dry soil, respectively, during the first several days of experiment, but were slight promoted thereafter. In contrast, treatment with Starane at 50 mgkg^(-1) stimulated at the beginning of experiment but inhibited following that time the activity of soil poly-phenol oxidases and acid phosphatase and soil respiration. Activity of urease was stimulated at the beginning but inhibited in the following days by Starane at 0.5 and 50 mgkg^(-1) dry soil, respectively. However, the pattern of stimulation of urease activity at first several days of experiment followed by reduction to the basil level was observed. With respect to invertase, its activity was constantly depressed in the presence of Starane.

文章论述了准分子激光消融眼球角膜的基本原理和数学模型，提出了把角膜治疗区域有目的地划分成30个或60个消融道的模式，通过MATLAB软件把理论计算曲线和实际模型曲线进行比较，得出它们的消融误差，并且成功进行了动物实验和盲眼实验，提前为角膜屈光的临床实验奠定了基础。

In the first experiment, ground pork ham, loin, belly and shoulder were mixed and homogenized with different percentage (0, 5, 10, 15, 20, 25, 30, 35 and 40%) of exogenous RO water and 0.95% salt solution, individually. In second experiment, only ground pork ham was mixed and homogenized with different percentage (0, 5, 10, 15, 20, 25, 30, 35 and 40%) of exogenous pork backfat. The electrical conductivity of these samples was determined and all data were collected and analyzed to obtain correction coefficient and regression formula for predicting fresh meat with different percentage exogenous water or fat. In final experiment, analyzed electrical conductivity, gel strength, hardness and fat particle stain of emulsion with different amounts of exogenous fat in two salt systems (2.5% salt and 2.5% salt + 0.3% phosphate).

However, when sitting for the learning achievement posttests, the experiment group, especially the mediocre and low achievers perform better than the control group. Therefore, we propose that the Embedded-Composite Assessment in the teaching is helpful for the experiment group to learn Factorisation, especially for the experiment group's mediocre and low achievers.

但在学习成就测验后测及学习成就测验前后测进步成绩上，实验组全组及中低分群都比对照组全组及中低分群的分数来得高，由此可推测「融入复式评量之实验教学」对实验组及实验组中低分群学习「因式分解」是有帮助的。
