Objective
Chlorine dioxide (CD) gas has been used as a fumigant in the disinfection of biosafety laboratories. In this study, some experiments were conducted to assess the inactivation of spores inoculated on six materials [stainless steel (SS), painted steel (PS), polyvinyl chlorid (PVC), polyurethane (PU), glass (GS), and cotton cloth (CC)] by CD gas. The main aims of the study were to determine the sporicidal efficacy of CD gas and the effect of prehumidification before decontamination on sporicidal efficacy. 相似文献32.

消费者是供应链的最终环节,也是关键的环节,从一定程度上影响供应链所有成员的行为。基于此建立的供应链中考虑消费者低碳偏好的两阶段动态博弈模型,表明不同决策机制下制造商的单位碳排放减少量对供应链成员决策的不同影响。消费者的低碳偏好会影响不同决策模式下的供应链的绩效,即两种决策机制下的碳减排水平相同,但集中决策下的收益和产量均高于分散决策情形;消费者低碳偏好增加或者减排成本影响因子下降,都将使得供应链各成员的利润增加,从而进一步促进企业投人更多的资源进行减排。 相似文献

Nonlinear vibration can cause serious problems in long span cable-stayed bridges.When the internal resonance threshold is reached between the excitation frequency and natural frequency,large amplitudes occur in the cable.Based on the current situation of lacking corresponding constraint criteria,a model was presented for analyzing the dynamic reliability of coupling oscillation between the cable and tower in a cable-stayed bridge.First of all,in the case of cable sag,the d'Alembert principle is applied to studying the nonlinear dynamic behavior of the structure,and resonance failure interval of parametric oscillation is calculated accordingly.Then the dynamic reliability model is set up using the JC method.An application of this model has been developed for the preliminary design of one cable-stayed bridge located on Hai River in Tianjin,and time histories analysis as well as reliability indexes have been obtained.When frequency ratio between the cable and tower is approaching 1∶2,the reliability index is 0.98,indicating high failure probability.And this is consistent with theoretical derivation and experimental results in reference.This model,which is capable of computing the reliability index of resonance failure,provides theoretical basis for the establishment of corresponding rule. 相似文献
