营养盐的含量与元素间的比值直接控制着生态系统的生产力和浮游植物的种类组成。近岸海区硅藻可占初级生产的75%,但其生长速率受Si(OH)4含量的限制。胶州湾浮游植物的物种组成以硅藻为主。用29Si同位素示踪培养方法,采用四极杆质谱同位素稀释技术同时测定了胶州湾硅的生成速率与溶解速率。胶州湾生物硅(BSi)的含量为0.90～1.14μmol/L,岩成硅(LSi)的含量为46.3～52.3μmol/L。岩成硅是生物硅的约50倍。胶州湾BSi的含量处于世界近岸海区的低值范围,LSi的含量与LSi/BSi的比值均处于高值区。BSi的绝对生成速率为4～6 nmol/L.d,比生成速率为6～17/d。BSi的绝对溶解速率为<9 nmol/d,比溶解速率为<23/d。进一步开展胶州湾不同季节水体中BSi的生成速率与溶解速率的研究,是深入认识海湾浮游植物生长限制及其资源可持续利用的基础。

We consider stochastic semi-linear evolution equations which are driven by additive, spatially correlated, Wiener noise, and in particular consider problems of heat equation （analytic semigroup） and damped-driven wave equations （bounded semigroup） type. We discretize these equations by means of a spectral Galerkin projection, and we study the approximation of the probability distribution of the trajectories： test functions are regular, but depend on the values of the process on the interval [0, T]. We introduce a new approach in the context of quantative weak error analysis for discretization of SPdes. The weak error is formulated using a deterministic function （It6 map） of the stochastic convolution found when the nonlinear term is dropped. The regularity properties of the It6 map are exploited, and in particular second-order Taylor expansions employed, to transfer the error from spectral approximation of the stochastic convolution into the weak error of interest. We prove that the weak rate of convergence is twice the strong rate of convergence in two situations. First, we assume that the covariance operator commutes with the generator of the semigroup： the first order term in the weak error expansion cancels out thanks to an independence property. Second, we remove the commuting assumption, and extend the previous result, thanks to the analysis of a new error term depending on a commutator.
