词汇 | stoichiometric |
释义 | stoichiometric adjective chemistry specializeduk /ˌstɔɪ.ki.əˈmet.rɪk/ us /ˌstɔɪ.ki.əˈmet.rɪk/ relating to the relationship between the quantities of substances involved in a chemical reaction and the substances that are produced as a result of that chemical reaction: 化学计量学的 It is possible to predict the effect of changing concentration by referring to the stoichiometric equation for the reaction.可以通过参考反应的化学计量方程式来预测改变浓度的效应。 These salts were added in sufficient quantities to obtain the same stoichiometric balance as sea water. Stoichiometric equations can be used to calculate the volumes of the products of a reaction. There is a region where the fuel to oxidizer ratio is sufficiently close to the stoichiometric ratio for combustion to occur. One method is based on the stoichiometric calculation of the reactive iron.

Here stoichiometric theory from ecology may be of some use. The use of such selfprocessing peptides has allowed the production of stoichiometric levels of multiple gene products along with appropriate compartmentalisation. Stoichiometric conversion of oxygen to superoxide anion during the respiratory burst in neutrophils. But unlike any forces known in gravitational attraction, they had to be conceived as selective, limiting, and inoperative beyond a fixed (stoichiometric) stage. Replacement of a mutated endogenous gene might ensure the correct stoichiometric expression of the protein and its various splice variants. The stoichiometric ratio of gas mixtures (1) and (3) are kept the same. Covalently linking the components reduces the entropic penalty for complex formation and ensures a one-to-one ratio of the molecules, solving stoichiometric problems in sample preparation. The general picture one should take away from this brief review is one of great stoichiometric variability and plasticity at the base of autotroph-driven food webs. Thus, in a world with stoichiometric reality, an ecosystem can be maintained indefinitely in a state of high autotroph biomass and no (or low) herbivore abundance. By connecting key concepts of ecosystem ecology, evolutionary biology and biochemistry, stoichiometric theory integrates biological information into a more coherent whole that holds considerable promise for application in astrobiology. A formalism can be developed on the basis of the stoichiometric matrix of the reaction network, generalizing the formalism used in the literature to describe the metabolisms of alive beings. System descriptions (biological trend, bioenergetics, nutrientbased), approaches (curve fitting, factorial, compartmental) and mathematics (growth functions, regression, differential and stoichiometric equations) are sometimes mixed within a model (hybrid model). Stoichiometric theory provides an alternative or perhaps a complementary mechanism to explain the very long persistence of an autotroph (stromatogenic cyanobacteria)dominated world. The vortometric burner can burn hydrocarbon liquid and gases at near stoichiometric proportions of air and thus can attain the highest levels of combustion efficiency.
