In this study, the spatial structure of randomly distributed clusters of fungi An0429 spores was simulated using a cluster aggregation (CCA) model, and the single scattering parameters of fungi An0429 spores were calculated using the discrete dipole approximation (DDA) method. The transmittance of 10.6 µm infrared (IR) light in the aggregated fungi An0429 spores swarm is simulated by using the Monte Carlo method. Several parameters that affect the transmittance of 10.6 µm IR light, such as the number and radius of original fungi An0429 spores, porosity of aggregated fungi An0429 spores, and density of aggregated fungi An0429 spores of the formation aerosol area were discussed. Finally, the transmittances of microbial materials with different qualities were measured in the dynamic test platform. The simulation results showed that the parameters analyzed were closely connected with the extinction performance of fungi An0429 spores. By controlling the value of the influencing factors, the transmittance could be lower than a certain threshold to meet the requirement of attenuation in application. In addition, the experimental results showed that the Monte Carlo method could well reflect the attenuation law of IR light in fungi An0429 spore agglomerates swarms.

Partial Reinforcement Training

3 groups of albino rats were given 96 acquisition trials in a runway. One group (C) was given consistent reinforcement, while the other 2 groups (PN, PR) received the same partial reinforcement pattern, RRNNRRNN, on each day. Following Trial 4 for Group PN and Trial 5 for Groups PR and C., Ss were given intertrial reinforcement. In extinction the groups were ordered PR, PN, C, with Group PR being most resistant to extinction. Taken in conjunction with the results of studies involving abbreviated training, the findings were interpreted as supporting the view that the same variables or processes influence extinction performance following both abbreviated and extended training. The results were further interpreted as supporting the modified aftereffects hypothesis.

Terminal Level

Four groups of 8 albino rats each were magazine trained under high or low drive, barpress trained with the same 32% sucrose incentive or water (designed to produce “frustration”), and tested in extinction with an inoperative magazine. The results confirmed earlier ones obtained with an inaccessible-food training operation in that the major factor determining extinction performance was terminal level of reinforced responding in training.

Daily Block

Trial spacing was studied over 120 acquisition trials and 20 each of extinction, reacquisition, and re-extinction, using five intertrial intervals from 40 sec. to 120 min. in between four daily trials. Throughout acquisition, performance of the 120-min. group increased throughout the course of a daily block, while the others first increased, then decreased. Spontaneous regression persisted throughout acquisition. Extinction performance was not systematically related to trial spacing, and no evidence for spontaneous recovery was found. Changes in measured spatial variability in the alley indexed learning but did not differentiate trial spacing effects. The results generally failed to confirm qualitative hypotheses about trial spacing derived from statistical learning theory.
