The study of critical phenomena has led to the notions of scaling and universality and has spawned the renormalization group, which shows how identical behavior at long length scales can arise from widely different microscopic interactions.
对临界现象的研究引出了新的尺度分析和普适性的概念,产生了重整化群。重整化群显示了相当不同的微观相互作用是如何在长程尺度范围产生同样的行为。

The results showed that the influence of negative interactions among woody species in this subtropical plot was greater than other studied tropical plots. All the 52 examined woody species at the Fushan plot behaved as diversity repeller within a 50 m scale and did not show scale-dependent neutral behavior.
结果显示,种间竞争作用在亚热带的福山森林样区内的影响力比在热带样区更为显著,在50 m空间尺度下,所有检验的52种福山林木物种是多样性排斥者,并且其中性性质并不会因空间尺度不同而变化。

After that, the important equation for calculating reverberation time is given based on the definition of reverberation time and least squares method. Finally, we use our new method to calculate reverberation time in a rectangular enclosure; we also compare our results with those given by experiment and Sabine's equation. The comparison shows that the new method is more effective and accurate than Sabine's equation in calculating reverberation time of small enclosures.
给出了描述小尺度封闭空间内声场的有限元模型;在该模型的基础上推导了计算小尺度封闭空间内混响时间的方法,并编制了相应的计算机程式;在算例部分,计算了一矩形封闭空间内的混响时间,通过与实验结果进行比较,验证了这一方法的正确性。

The intensification phenomenon at 1-meter scale was not found. The larval density in water column might be highly heterogeneous even in very small scale. On the other hand, we consistently found higher settlement density in sand areas than in reef areas. This phenomenon may well have been caused by the intensification
本研究结果在1公尺的空间尺度下并没有发现附苗强化现象,但是礁区的附苗密度却如预期低於砂区,推测可能是1公尺空间尺度内幼生数量过於不均匀,相差5倍的附苗板面积不足以造成幼生附苗密度的变异,而礁区与砂区则由於面积相差相当大因此可以发现附苗强化现象。

With unit integrating and scale conversion, the transpirations determined by lysimeter and L I21600 stoma mete r are analyzed wit h Variance Analysis Method. The results s how that the difference between species is significant (P.05), but t he difference between methods is not significant. It indicates t hat t he scale conversion between leaf level and plant population level based on canopy and leaf area index is successful.
