Net primary production of the forcst(Pn) was 29.612t. hm-2.a-1, and that of trunk,branch,leaf,root,and fruit and flower,8.181(27.63%), 3.403(11.49%), 4.281(14.46%),13.165(44.46%), and 0.582(1.97%) respectively.
The mean abundance, biomass and production of meiofauna were 1.40x10~(6) ind·m~(-2), 1.05x10~(6)g dwt·m~(-2) and 9.45x10~(6) g dwt·m~(-2)·a~(-1) at B2 station in four cruises in Jiaozhou Bay in 2002, respectively.
(2) the biomass production and economic productivepotential are 1.3×10~3-4.0×10~3kg/ha·a and 2.7-6.3m~3/ha·a respectively,while the increament ratio are to 10.8 to 37.8 per cent and 38.8 to 134.1per cent respectively.
In the report, production capacity, production output, development condition and development trend of process and products in north America are introduced.
The derivative at the cost smallest,the profit biggest,and the application of the whole sale quantity lowest in the production output is the illustration in this aspect.
The energy production output time series of energy sources industry system shows chaos and system evolvements have irregular periods, which are proved by using state space and correlated dimension computing methods.
last in connection with BYQ Company production volume development target, conclude it is inevitable for BYQ Company to select the development pattern of reducing cycle time and improve output.
Based on the analysis on demand changes, the paper amends and perfects the model of EPQ (Economic Production Quantity), further studies the minimum EPQ and minimum annual total costs of single line and multiple lines, and improves the EPQ model.
In order to minimize the sum of the holding cost, setup cost and shortage cost, a multi-period production/inventory model under random demands was set up, which adopted(s, Q) policy for production/inventory control, that is when the stock level of finished goods was less than s, production preparation started, and the production quantity was Q.
Besides, Respectively built grey GM(1,1)models of en- ergy industrial production quantity and consume quantity. The results of quantified analysis provided reliable scientific for the quantitative analysis and decision.
The uniqueness of the geodesic by its initial values severely restricts the choice of the fiber path and is an obstacle to the production of optimized structures.
Under a kind of utility function and production function, we prove that these conditions are satisfied and the economy at least has an optimal growth path.
This paper formulates a kind of dynamical macro-economic model based on Sidrauski's work, then presents the sufficient and necessary conditions of the stability of model at equilibrium states, and shows some results for special production functions.
inaequivalvis the net accumulation of anaerobic products at the lowest oxygen tension tested (0.5 ppm) was still substantially less than the level of production output in complete anoxia.
The model and the resulting closed form equations allow the FMM designers and operation engineers select the most appropriate parameters for the maximum production output rate.
Efficient scheduling rules for the bottlenecks and input rules are also suggested with the objectives of maximizing the production volume under a short cycle time.
This insight justifies, to a certain extent, the use of full costs to support decisions on the short-term production volume, which is a behaviour that can be observed in practice rather frequently.
This paper reports on the methods smallholders employ to shade soil, seedlings, plants and crops to protect them from environmental stresses and to improve their yield capacity.
Choice of parents and selection procedures were carried out on the basis of yield capacity, resistance or tolerance to a fungus and virus disease, resistance to Cylas formicarius F.
