The research indicates that it is feasible to verify an underground nuclear test by monitoring 37 Ar sample from the underground soil.

Using this method, we researched a synthetic discrimination method of nuclear test seismic monitoring with fuzzy logic illation, and listed its theory framework.

This paper expounds that China has totally made 45 nuclear tests and all the tests were come off all right,and introduces something about Mr.

The results of erythrocyte micronucleus assay, spermatogonial chromosomal aberrations test, and the Ames test were all negative.

The Ames test, Erythrocyte micronucleus assay,Spermatogonial chromosomal aberrations test and In vitro mammalian cell gene mutation test were used.

Methods:The genetic toxicity of SPFF was investigated by the Ames test, the micronucleus assay and chromosomal aberration test of CHL.

Acute toxicity and micronucleus test of compound additive of aloe;

The application of micronucleus test in Vicia faba root tip cell in environmental mutagens detection;

Micronucleus test on antibiotic 89 07 in mice;

In order to provide scientific toxicological basis,the Ames test and micronucleus test were done.

MATERIALS AND METHODS:The mutagenicity of N-Nicotinyl-aspartic acid was examined using Ames test, CHO cell chromosome aberration test and micronucleus test.

To investigate the genotoxicity of CpG ODN by micronucleus test.

The procedure for calculating the thermal efficiency in acceptance test of a 300MW gas-steam turbine combined cycle unit is presented, the test data has been dealt with and the test output and thermal efficiency of the unit are also calculated by the processed and analyzed test data.

By analyzing the basic principle of the correction about the acceptance test of the turbine flow passage retrofit, some important items about correction are put forward such as the ways and methods of correction calculation, correction items of test results about the acceptance test to flow efficiency.
