There were lesser and fewer in commercial species and its numbers in the cover net, and the sum of Nemipterus virgatus , Saurida tumbil , Upeneus bensasi , Trachinocephalus myops comprised 95.4% in number and 86.0% in weight of sample catch in the cover net,respectively. The high percentage of juvenile commercial species that were undersized in the codend showed 30.3 mm square mesh codend had more serious damage to most juvenile commercial species, approaching or exceeding 50% in percentage of juvenile species which body length is smaller than fishable size- Trichiurus haumela, Priacanthus tayenus , Navodon tessellatus, Argyrosomus argentatus, Nemipterus bathybius and so on, even exceeding 90% in percentage of juvenile Sepia spp, Loligo spp and Parastromateus niger. In particular, 50% selection lengths ( L 0.5) caught Saurida tumbil and Nemipterus virgatus were smaller than their minimum fishable size.

ABSTRACT The ionic strength of mobile phase can significantly affect the peak shape of ionogenic compounds such as antibiotics in reversedphase high performance liquid chromatography. The influence may be attributed to overloading of ionogenic analytes in lower ionic strength mobile phase.
在反相高效液相色谱过程中,流动相的离子强度可显著影响可解离的化合物如抗生素的色谱峰形,原因在于流动相的离子强度较低时,色谱填料的固定相易于过载,使离子化的化合物的色谱峰形呈典型的过载特征――峰形接近直角三角形。

The outstanding feature of the new cutting dynamometer contrary to other type of dynamometer sensor is that it is more similar to general lathe tool. It can be installed on knife rest, so it is same wit practice state of cutting. Sensitivity of dynamometer is more high, especially main cutting force can attain 7.4pC/N. The calibration results show that it has high static linearity, and its natural frequency is greater than 5 kilohertz, so the cutting dynamometer has fully reached the dynamometer standard stipulated by CIRP-STCC.Finally, in order to measure the cutting force, the orthogonal experiment method in which the three factors are the diameter of cutting, feed and spindle speed is performed.

Result A strain of Pseudomonas cepacia was detected in 1.6% compound quaternary ammonium disinfectant before application. The amount of the germ was 1.21×105cfu/ml. The strain had the similar resistance to chlorine-containing disinfectants and glutaraldehyde compared with Staphy aureus. The contaminated disinfectant could still thoroughly destroy the antigenicity of HBsAg with 60min's contact after diluted for 5-20 times.
