摘要：
We study the Vicia faba leaf tip cell-micronucleus test (Vicia-LTMT) to expand the monitoring scope of the Vicia plant. The paper reports positive findings in detecting poisonous gas (xylene, hydrogen sulfide) by the utilization of Vicia-LTMT. The in situ monitoring of air pollution in Huangshi, an industrial area, was conducted at four locations, where seedlings were exposed for 4 h. The micronucleus (MCN) frequencies of the V. faba leaf tip cells in each location were obviously higher than the control (F > F0.01, P < 0.01) by statistical analysis. The results show various degrees of pollution in these industrial areas.

摘要：
By using FIM, high-transition-temperature superconducting Bi2(Sr, Ca)3Cu2O(y) has been examined with H-2 and Ar imaging gases. Two kinds of FIM images, lines and spots, have been observed and analyzed. Both patterns convincingly show the lamellate structure of the specimens. The periodicity of the FIM image patterns is consistent with the proposed models, and some new patterns are observed and discussed.

摘要：
The rapidity distributions of shower particles in high-energy nucleus-nucleus collisions are investigated and compared with that in hadron-hadron and hadron-nucleus collisions. The remarkable difference in the correlation between rapidity distribution and multiplicity in the three cases, as well as the scaling of rapidity distribution in the target region and the nonscaling of the same distribution in the central region, are explained.
