We spent $272 million on flight simulators in 2000, and we'll spend a similar amount this year. Anyone who thinks that the annual charges for depreciation don't reflect a real cost - every bit as real as payroll or raw materials - should get an internship at a simulator company. Every year we spend amounts equal to our depreciation charge simply to stay in the same economic place - and then spend additional sums to grow.And growth is in prospect for FSI as far as the eye can see.

2000年我们投资2.72亿美元在购买飞行仿真器上头，今年的投资金额也约当此数，有谁胆敢说每年的折旧费用不算是真正的成本的，应该请他到飞行仿真公司打打工，让他知道每一分折旧都跟薪资或原料成本一样真实，每一年我们都必须投入约当于折旧金额的资金在更新设备上，以维持既有的竞争优势，而如果我们想要成长的话，就必须再投入额外的资金，对于FSI而言，其目前成长的前景依然可期。

The experiments for determining the reaction kinetics of Daqing atmospheric residue were performed in a continuous flow, expanded bed rector. Four-lumped reaction kinetic model was developed to account for various feed and product fractions of Daqing atmospheric residue (gases, gas oil, residue and coke). The amounts of olefins and alkyls in the gas products were further analyzed to determine reaction kinetics of gas product distributions. Hence, a combined five-lumped reaction kinetic model was obtained for catalytic pyrolysis of Daqing atmospheric residue. The kinetic constants both in four-lump model and five-lump model were evaluated. A simulator for catalytic pyrolysis process was developed by incorporating the five-lumped kinetic model into the hydrodynamic flow model.
