| 4. | The kinematics model , kinetics model , infrared radiation model and radar cross section model of bomer and the kinematics and kinetics of infrared guided missile and radar guided missile are studied 研究了轰炸机的运动学、动力学模型,轰炸机红外目标辐射模型与雷达散射截面积( radarcrosssection , rcs )模型。研究了红外制导导弹与雷达制导导弹的运动学与动力学模型。 |
| 5. | What ’ s more , this paper takes the effect of crown wall rock and mid - board foundation reinforced parametric variation on tunnel structure stress and stability into account grounded on building typical section model of i wall - rock sector 另外,本文还通过建立类围岩地段隧道典型断面模型,分别考虑拱顶围岩和中墙地基加固参数的变化对隧道结构受力和稳定性的影响。 |
| 6. | Fitting results of three non darcy seepage models including three - parameter model , power exponent model and two - section model were pretty good , and broken line model could be simplified to the forms of linear permeability model and darcy model 试验与分析结果表明,三参数模型、幂指数模型和非线性分段模型这3种非达西渗流模型的拟合效果较好;折线渗流模型简单实用,在特殊情况下可以简化为线性渗流模型或达西定律。 |
| 7. | This paper , which aims at the developing strategy of express service , researching and analyzing chinese and foreign express corporations current situation , forecasts the demand of chinese express market in fifteen years with conic section model on the base of statistics 本文立足于快递业的发展战略,调查并分析了中外快递公司在中国发展的现状,根据实际的快递业务数据,利用二次曲线预测模型方法对未来15年内的快递市场需求量进行预测。 |
| 8. | First , description of the change of financial component is provided in the paper , which indicates possible earnings management in the researched years . second , evidence of earnings management of listed company is provided as a whole by time - series models and cross - section models 首先,通过对st公司与控制公司会计指标的描述性分析,指出了st公司在被特别处理前后年度以及被特别处理前年度的可能存在的盈余管理行为,并得出一些初步的假设性结论。 |
| 9. | With the aid of these blocks , it is convenient and flexible to make up different kind of automatic - controlled simulating system and so to accomplish different kind of automatic adjusting task . this paper is focused on the construction of the simulation model of ccs by using the contrived control section model . the ccs employs advanced direct energy balance control strategy and can simulate different running patterns such as turbine following boiler pattern , boiler following boiler pattern , etc . two independent control loops : power control and frequency control , are used in the contrivance of deh and they are separately corresponding to the normal condition and the abnormal condition 本文利用开发的控制环节模块,着重建立了协调控制系统的仿真模型,该协调控制系统采用了先进的直接能量平衡控制策略,并能仿真机跟炉、炉跟机、机炉协调、手动以及定压和滑压等运行方式;开发的功频电液系统模型采用了功率控制和频率控制两个独立的控制回路,能够在机组正常运行和启停时对汽轮机进行控制。 |
| 10. | The author analyzed newly develops of the middle vocational education and the author also analyzed difficult position of the middle vocational education . though rethink about tradition of middle vacation , the author thought that the traditional curriculum structure of the middle vocational school is three sections model . the theory curriculum and practice curriculum was departed 笔者在对目前中等职业教育发展的形势和面临的困境进行了分析,对传统中等职业教学模式进行了反思,认为传统中等职业学校的课程结构是“三段式” ,普遍存在着理论课与实践课的教学相分离、 “五重五轻”现象。 |
