In overcast and rainy days,ultraviolet radiation has little contribute to ozone concentration,and the R is 0.881.

而在阴雨天气紫外辐射项对O_3的变化没有显著性影响,R值为0.881。

3. Ultraviolet radiation can induce the apoptosis of human nasal septal chondrocytes, which can be used for detecting the influencing factors on the apoptosis of chondrycytes in vitro.

3、紫外线可诱导体外培养的人鼻中隔软骨细胞凋亡，这一模型可应 用于检测体外培养软骨细胞凋亡的影响因子。

The best experiment solutionwould be: RGD concentration, 0.5mg/ml, EDC concentration, 3%and ultraviolet radiation time, 60 minutes.

最佳试验方案为RGD浓度为0.5mg／ml，紫外辐射60分钟，EDC浓度为3％。

After parallel pretreatment with ultraviolet radiation and polarization, heatcuring denture acrylic-3-resins substrates were deposited with nanometer amorphous diamond film.

在热凝造牙粉与义齿基托材料表面采用紫外光照射与极化两种预处理方法，分别在其表面镀制50nm和100nm的纳米非晶金刚石薄膜。

The antagonistic products produced by PNB were heat-stable; the inhibitory activities of PNB was not lost upon treatment with proteanase K,α-chymotrypsin, and ultraviolet radiation, but sensitive to trypsin, pepsin, and subtilisin.

紫色非硫光合细菌拮抗产物具有很好的热稳定性；对蛋白酶K和α-糜蛋白酶不敏感，对胰蛋白酶、胃蛋白酶和枯草杆菌蛋白酶较敏感；但其抑菌活性不受紫外照射的影响。

The protection of ultraviolet radiation is becoming mo re and more important with the improvement of people’s health knowledge.

随着人们健康意识的增强,紫外线的防护变得越为重要。

The rates of transmittance and reflectance of fabrics of Nomex and Kevlar are high to visible light, then to near infrared radiation, and low to ultraviolet radiation.

和Kevlar~(?) 织物对紫外光的透、反射最低，其次是近红外区域，可见区域最高。
