Abstract: In that paper some aspects of electron-photon interactions are discussed. Although that subject has already been treated in many publications there are still some unsolved problems: like relationship between photon duration and electron transit time, or conditions and probability of interaction processes. These are addressed in this paper and new results are obtained. For example, the electron-photon interaction process can only occur if the electron transit time from an energy level to another one is equal to the length of the photon in time or by other words to the duration of the interacting photon. That means the energy transfer in a specific process requires a specific processing time, i.e. the processing time and the processing energy are strictly connected to each other. If these two conditions are not satisfied simultaneously the interaction cannot be carried out. Further, it can be stated: time is passing as changes occur in the state of the material, like changes in its energy level, location, motion, composition, etc. To perform such a change, some energy is needed. If the inherent energy of a specific physical process which is utilized to carry out the change in the state of material is higher, the change is carried out in a shorter time. This relationship presents strict connection between energy and time

Abstract: We try to develop a new measurement method for cleanliness evaluation of inner surface of narrow tubule.In this measurement method, we use the infrared spectroscopy and the partial least squares regression (PLSR).The absorption spectrum is measured by using fiber probe and cone mirror.We measure the spectra of the known amount of dirt.We build a calibration curve using these spectra and the PLSR.Next, we measured spectrum of inner surface of narrow tubule, and calculates the amount of remaining this dirt by the calibration curve.This method can be measured in a non-contact and non-destructive.This method can identify the remaining position and the type and amount of dirt.In this paper, we propose this measurement method as new cleanliness evaluation method has overcome the problems that exist in the cleanliness evaluation.
