英文摘要	Meteoroids always posed a great hazard to spacecraft security. A meteoroids stream assembled by a large massive body will further thance the hazard severalfold. For example, the radiant of Northern Taurids (NTA) will be occulted by the Moon on Nov. 12, 2011..nce the gravitational lensing effect of massive bodies can gather together the orbits of meteoroids, the observable flux of meteoroids will crease. In this paper a set of numerical methods was built to discuss the observational effect of this kind of phenomena. The ZHR of TA is generally small. But it can be local strong on the Earth by the lunar gravitational assembling. The calculated result suggests that a n times stronger than normal NTA will appear in the sea area of Tristan da Cunha islands during 00h45m UT to 02h00m UT on Nov 2011. 2007 Elsevier B.V.
