Objective To observe the production and removal of photo-product, cyclobutane pyrimidine dimers, in HaCaT cells induced by UVB irradiation and intervention effect of ligustrazine, and to investigate its photo-protective mechanisms on HaCaT cells damaged from UVB irradiation.

目的观察中波紫外线辐射后永生化角质形成细胞株中光产物环丁烷嘧啶二聚体的产生和清除情况，观察川芎嗪对UVB辐射后细胞光产物的影响并探讨其保护作用机制。

Ozone College depletion in stratosphere has led to the increase of solar UV-B radiation reaching to the earth surface, which would damage DNA of plant epidermal cells and produce cyclobutane pyrimidine dimmers (CPD and 6-4 photoproducts.

臭氧衰减导致地表紫外辐射增强，而紫外线辐射对植物表皮细胞的DNA具有损害作用，可导致环丁烷嘧啶二聚体和6，4-光产物的形成。

To expand through demonstrater to hybrid cattles.To expand through provicing fine embrgo and transplanting technology to breeding.

杂交牛规模化快速育肥技术通过生产示范进行辐射推广，繁育技术通过提供优秀母牛胚胎和胚胎移植技术服务进行辐射。

The growth rate and enzyme activities significantly decreased when dikaryotic hypha ofPleurotus ostreatus were irradiated with γ-rays and subsequently treated with either caffeineor Na2-EDTA in comparison with γ-rays treatment alone. The inhibition effect of treatmentwith either caffeine or Na2-EDTA before irradiation was more obvious than that after irradi-ation. Treatment with either caffeine or Na_2-EDTA could cause biological damages on hyphawhen the concentrations of caffeine and Na_2-EDTA were up to 0.5 and 1.0mg/ml respective-ly.

侧耳双核菌丝经γ射线辐照后用咖啡因或Na＿2－EDTA处理，其生长速度和漆酶及多酚氧化酶活性较单一γ射线辐照明显降低，使辐射损伤加剧；辐照前用咖啡因和Na＿2－EDTA处理，抑制辐射损伤修复的效果优于辐照后处理；咖啡因和Na＿2－EDTA浓度分别达到0.5和1.0mg／mL后，单独处理侧耳菌丝会直接引起生理损伤。

Specialized dosimetric models and computational methods are needed.

肿瘤及周围正常组织、靶区中辐射敏感的细胞和细胞核的吸收剂量及其分布是辐射效应分析时重要的物理量，其估算需要特殊的剂量学模型和计算方法。

The bone dosimetric values are influenced by the parameters of skeleton mass.

鉴于骨骼组织不同部位的辐射敏感性存在差异［2］，特别是已确认骨髓的造血干细胞和衬在骨表面上的成骨细胞是骨骼中致癌危险的靶细胞，因而ICRP30号出版物［3］详细介绍了估算骨骼靶器官的吸收剂量的骨剂量学模型，使骨剂量的计算趋向精确。1995年，ICRP又专门编著了用于辐射防护的骨骼解剖和生理参数的70号出版

The results showed that there were prominently positive correlations between rates radioactivity of SOD and POD and a good minus correlation between rates radioactivity of SOD and PPO. With irradiated by 60Co-γ ray of 10GY, rates radioactivity of SOD and POD were highest, and rate radioactivity of PPO was secondary, and rate radioactivity of CAT and the content of malondialdehyde were eighthly.

结果表明，SOD酶活力与POD酶活力之间呈显著正相关R=0.656(上标*，SOD比活力与PPO酶活力、PPO比活力之间呈极显著负相关R=-0.716(上标*， R=-0.714；SOD酶活力、POD酶活力以10GY辐射处理值最高，10GY辐射处理的PPO酶活力居第2，丙二醛含量及CAT酶活力居第8。

Different from those predominantly body-confronted movements as football which are like a fight between solders at close range, golf is more like a generals' battle. It not only shows the graceful art of the gestures, but also incarnates the will, absorption, intelligence and confidence of the golfer. The objects of golf are those minded, intellig ent and endurant successful people, thus the attracted company must be high-class.

如果说足球等以肢体为主的对抗运动像将士在战场上的短兵搏杀，凸现的是肢体艺术，辐射的是大众群体，高尔夫就更像是统帅之间的较量，不仅体现在优雅的肢体艺术，更体现明星的意志、专注、智慧、信心，是精神上的对决——高尔夫战场的辐射对象是那些有思想、有智慧、有毅力的成功人士群体，因而高尔夫运动吸引的商家也必须是高端的。

Secondly, we discussed the effects of spontaneously induced coherence on the absorption properties of nearly equispaced Ladder-type system and found that EIA can occur due to the effects of spontaneously induced coherence.

然后我们讨论了在近等间隔的阶梯型三能级原子系统中，自发辐射诱导相干对其吸收特性的影响，发现利用自发辐射相干也可产生电磁感应吸收。

Classical electric mechanics confirmed that accelerating charge must eradiate electromagnetic wave, while at the same time, quantum theory confirmed electron accelerates in the same energy-interzone in atom never radiate electromagnetic wave, is it possible to be united in theory?

经典电动力学认为加速运动的电荷能够辐射电磁波，而量子力学指出电子在同一能级内做加速运动不能辐射电磁波，能否把它们统一起来？

I am accused of being overreligious," she said in her quiet, frank manner,"but that does not prevent me thinking the children very cruel who obstinately commit such suicide.""

客人们在卡罗利娜·埃凯家里，举止就文雅一些，因为卡罗利娜的母亲治家很严厉。

Designed by French fashion house Herm è s, this elegant uniform was manufactured in our home, Hong Kong, and was the first without a hat.
