An air pressure wave which moves ahead of the main blast wave for some distance as a result of a nuclear explosion of appropriate yield and low burst height over a heat-absorbing(or dusty) surface. The pressure at the precursor front increases more gradually than in a true(or ideal) shock wave, so that the behaviour in the precursor region is said to be non-ideal.  2, record 1, English, - precursor%20front

Front de pression qui précède le front principal. Il est provoqué lors d'une explosion nucléaire d'une certaine puissance, à basse altitude au-dessus d'une surface thermo-absorbante (par exemple poussiéreuse). La pression sur le front précurseur augmente plus progressivement que celle d'une onde de choc théorique, aussi dit-on que les conditions au voisinage du front précurseur ne sont pas conformes au modèle calculé.  2, record 1, French, - front%20de%20pression%20pr%C3%A9curseur

Onda de presión en el aire que precede a la onda de choque principal. Se forma como resultado de una explosión nuclear de determinada potencia a baja altura. A medida que avanza forma una superficie que absorbe calor (o polvo). La presión del frente previo aumenta de forma más regular que la onda de choque teórica, de manera que se puede decir que su comportamiento no es el ideal.  1, record 1, Spanish, - frente%20previo%20de%20presi%C3%B3n

One of the gaits of the five-gaited horse, the slow gait is sometimes called a "stepping pace" which means that two legs on the same side of the animal move simultaneously, but the hind foot contacts the ground slightly before the front foot. The slow gait is the precursor to the rack.  1, record 2, English, - slow%20gait
