By means of the cytokinesis block micronucleus(CBMN) assay for the CHO cell,the synergism effect of 4 CP and FA on the cytotoxicity parameters were evaluated.

In the traditional luminescent bacteria toxicity test,the test result is not stable and the use of virulent substance HgCl_2 as the toxicity reference substance engenders environmental pollution.

Only 7 heavy metals' toxic coefficients are used to assess pollution degree of heavy metals in many papers that use the method of Potential Ecological Risk Index(RI),but there are still other important heavy metals not employed to calculate toxic coefficient.

By comparing test data of physical parameters of cores with those derived from the interpretation of the diagram of well logging, the authors found a tendency that the wave velocity changes with the well depth measured from core tests coincides with that obtained from acoustic logging.

The noodles’ physical parameters (such as hardness, cohesiveness, springiness and so on) and the edible qualities were also studied.
