| 5. | In this paper two new test statistics by using matching the first three moments approach are proposed to approximate fgls ( ) by x2 and f variables . a comparison with modified f - test by wu et al ( 1988 ) is completed 本文用“前三阶中心矩相等”法,提出了两种新检验,分别用卡方统计量和f统计量去逼近( f _ ( gls ) ( ) ) ,并与wu , holt和holmes ( 1988 )提出的修正f检验进行了比较。 |
| 6. | In this paper two algorithms have been proposed to track the low - elevation targets in the presence of multipath : the interacting multiple model ( imm ) algorithm and the non - gaussian filtering algorithm . two models are used in the interacting multiple model m ) algorithm 本文研究在多路径传播的条件下跟踪低空目标的滤波技术,给出了两种滤波算法:交互多模算法( imm )算法和非高斯滤波算法。 |
| 7. | In this paper two - generation reproduction toxicity of fenvalerate , a - cypermethrin , chlorpyrifos , and triazophos was tested in a 21d period with water flea , daphnia magna , . the toxicity indicator included longevity , body length , days to first brood , days to first pregnancy , number of youth per female , intrinsic rate of natural increase ( r ) , and number of broods per female . accordingly , the dose - response relations and relations between the chronic responses and enzyme levels were investigated 为了确定水蚤体内生化指标与慢性毒害效应之间的关系,特别是在低浓度暴露状态下生化指标改变的生物学意义,以便能更准确预测早期农药对水蚤种群的潜在危害,本文以浙江省常用杀虫剂氰戊菊酯、高效氯氰菊酯、三唑磷和毒死蜱进行了大型蚤( d . magna )的急性和慢性毒性试验(包括子代水蚤的恢复试验) 。 |
| 8. | Usually we linearize them approximately in industrial process , but in some cases this ca n ' t satisfy the request of automatic control which makes us consider the nonlinear factors in the industrial process . in practical process of power plants the typical structure nonlinear case is dead - zone and the latter case is the nonlinear variance of objects ' parametres with the changes of working condition . the nonlinear research is parallel with the linearity and adaptive method can be used to deal with nonlinear cases . in this paper two adaptive control methods are used to solve the problems brought by the dead - zone of boiler negative pressure system and the nonlinear changes of the milling system ' s character parameters , which achieved good results 在生产中通常对非线性作近似线性化处理;但在某些情况下线性近似达不到自动控制的要求,必须对生产过程中的非线性情况进行考虑。在火电厂的实际生产中,典型的结构非线性之一是死区;参数非线性多发生在控制对象特性随工况变化而变化,表征其特征参数变化呈非线性。非线性控制的研究与线性控制的研究是并行的,针对非线性情况,可以采用自适应的控制方法。 |
| 9. | Medical image registration and fusion technique is a research hotspot of medical image processing these days . by registering and fusing the intra - modality and inter - modality medical images , doctors could diagnose and surveil the progress of illness and set down the more reasonable treatment plan . in this paper two rigid registration methods were described 医学图象的配准及融合技术是当前医学图象处理研究的热点,通过把来自同一设备或不同设备的医学图象配准、融合,可以协助医生诊断、监视疾病的发展过程及制定合理的治疗方案。 |
| 10. | In recent years , it is obtained from experiments that water infiltration is affected by air pressure , the problem on one - dimensional water infiltration is soloed by many researchers . in this paper two - dimensional water infiltration with air - out is considered and numerical simulation is made . unsaturated infiltration is the process of factors coupling each other 近年来,许多研究人员从实验中得出了气体压力变化对水流入渗有影响,并对一维水流入渗问题进行了求解,本文将进行考虑气体排出过程影响的二维水流入渗问题的数值求解。 |
