  the beam
Two plane-parallel wettable plates are immersed in the liquid in symmetrical positions with respect to the point of incidence of the beam on the liquid.
      
If detected, at the same geocentric distances (2-4RE) the "continuum" demonstrated a strongly variable and perturbed character, as well as a considerably larger extension of the beam over the geomagnetic latitude (10°-20° and more).
      
It examines the effect of the field of the beam and of the inherent volumetric charge of the tag on the results of the measurements; the conditions under which this effect can be neglected are calculated.
      
Experiments show that under these conditions the direct flow hardly goes beyond the limits of the beam.
      
Inflow into the main stream takes place at every point on the lateral surface of the beam [7], with the possible exception of the region near the emitter where the acoustic field is substantially nonuniform [8].

The vegetative nucleus function on division of the generative cell during the development of the male gametophyte of clivia nobilis was first studied by applying the Nd.YAG laser microbeam technique. The experiment revealed that the pollen tube could still grow to a certain length and the generative cell could enter the pollen tube normally after the vegetative nucleus was destroyed by using laser microbeam, but the genetative cell finally stagnated at the prophase or few at the early metaphase of the mitosis....

The vegetative nucleus function on division of the generative cell during the development of the male gametophyte of clivia nobilis was first studied by applying the Nd.YAG laser microbeam technique. The experiment revealed that the pollen tube could still grow to a certain length and the generative cell could enter the pollen tube normally after the vegetative nucleus was destroyed by using laser microbeam, but the genetative cell finally stagnated at the prophase or few at the early metaphase of the mitosis. The results directly demonstrate that the vegetative nucleus may have a physical or physiological function on division of the generative cell. This experiment also shows that the laser microbeam technique has a wide practical prospect in research on development of the male gametophyte or more of the plant reproductive biology.
