White Rainbows. Rainbows can even come in the color of white. This type of rainbow is also called a cloud bow and a fog bow. The reason for these names is that [it] is produced by clouds of fog or raindrops. This type of rainbow appears as a white hyperbola shaped rainbow above horizontal clouds of moisture. It is best seen when flying in an aircraft above the clouds or on a high mountain 4, record 1, English, - white%20rainbow

L'opacification du cristallin peut commencer par la périphérie, laissant pour un temps le noyau transparent; le malade est alors plus gêné à la semi-obscurité qu'à la lumière vive, car, dans ce cas, la pupille en myosis fait écran et masque les opacités, supprimant ainsi des phénomènes de diffraction très gênants et responsables souvent d’une diplopie. 2, record 3, French, - pupille%20myotique

Les études de structures au moyen d’électrons accélérés par des potentiels de l'ordre de 50 kV utilisent des appareils appelés diffractographes électroniques qui ont de nombreux points communs avec les microscopes électroniques ordinaires. Le principe en est le suivant : un faisceau d’électrons émis par exemple par un filament de tungstène, dans une enceinte où règne un vide poussé, est canalisé par un collimateur(...) et accéléré par une tension variant entre 30 et 100 kV. Les échantillons sont examinés soit par transmission(ils doivent alors être sous forme de films très minces), soit par réflexion(étude de couches superficielles). L'observation se fait sur écran fluorescent; l'enregistrement, sur plaques photographiques. La diffraction des électrons permet par exemple d’étudier un échantillon constitué de deux ou plusieurs phases distinctes; on obtient des diagrammes de diffraction présentant des taches différentes(...) 1, record 4, French, - diffractographe%20%C3%A9lectronique
