| 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。 |
