Influence of zinc oxide on the aging resistance of EPDM under UV irradiation;

The effects of UV irradiation time, monomer (MAH) and initiator (BP) concentration on grafting rate and gel content of grafted polyethenes were studied.

The effect of UV irradiation on the structure and properties of linear low-density polyethylene (LLDPE) and the mechanical properties of nylon 66 (PA66)/LLDPE blends were studied with FTIR and XPS, measurements of gel, melt index, and water contact angle, and mechanical property tests.

Prepared the monolploid cell suspension of Y11 yeast strain which screened specially for mulberry wine making, then dealt the suspension with ultraviolet radiation and microwave treatment, and further decided the optimal dilution concentration in two mutagenesis factor by flat plated counting method.

After successful preparation of monolploid cell of Y11 yeast strain(screened specially for mulberry fruit wine production),the cell was then treated by ultraviolet radiation and microwave mutation successively,then a quality strain ME44 was finally screened by three-class screening mode from large quantity of flat plates.

The space ultraviolet radiation and proton bombardment were simulated in the laboratory.

LLDPE modified by ultraviolet irradiation and toughening of PA66;

Study on ultraviolet irradiation graft modification of PBT melt-blown fabrics for blood filtration;

Using a equipment constituted of a high & low temperature testing box,a low-voltage mercury lamp and vacuumized tubes made of high purity quartz to simulate the temperature,vacuum and far-ultraviolet irradiation conditions of space environment,the stability of the phosphors SrAl_2O_4:Eu~(2+),Dy~(3+)to ultraviolet irradiation was investigated when utilized as the trace marker of spacecraft.

Influence of UV radiation on absorptivity of cavity of absolute radiometer;

The source is used for UV life acceleration test and for studying UV radiation effect of satellite mechanical and electrical products.

In order to give reference to application of this coating in space environment and to improve its capability and adaptability, the aging mechanism of the coating in several conditions, such as high vacuum, low temperature, ozone exposure and UV radiation were investigated in the paper.

To avoid cyanobacterial bloom,the method of ultraviolet irradiation was pointed out,and the inhibition effect of irradiation time,ultraviolet intensity and ultraviolet irradiation in the different growth stages on cyanobacterial growth was investigated.

Nano-silver/polyvinylpyrrolidone(PVP)composite materials were prepared with the silver nitrate solution containing N-vinyl pyrrolidone(NVP) at the room temperature,in which Ag+ ions were reduced to nano silver particles,and the monomers were polymerizated simultaneously by ultraviolet irradiation.
