The association between intrinsic noises and deterministic descriptions/properties of the rate equations for chemical reactions is analyzed using the linear noise approximation of the master equation. We illustrate that the effect of intrinsic noise is determined in combination by three components: the system size, the matrix associated with reaction kinetics, and the eigenvalues associated with the system’s dissipation. Generally, a more attractive dynamics tends to attenuate the intal fluctuations more significantly because intrinsic noises are inversely proportional to the absolute value of the real part of the eigenvalues. In addition, a higher reaction rate and larger stoichiometry coefficients will give rise to stronger intrinsic noise.

本论文以福鼎大白茶等为材料,通过水培和土壤盆栽试验,研究了不同浓度的砷、镉处理对茶树生长的影响及其在茶树体内的分布积累规律。结果表明:(1)砷对茶树生长的影响:在浓度为1～9 mg·L~(-1)砷胁迫下,水培茶树不仅新梢的萌发和生长受到严重抑制,而且出现明显的表观伤害症状,根据砷毒理图谱可进行茶树砷污染诊断。不同品种耐砷能力有一定差异,福鼎大白茶＞名山213＞名山131。砷胁迫浓度≥2.0 mg·
