紫外线

Make-believe summer lasts for a minute or two as kindergarten children in sunless Lovozero bathe in ultraviolet light.

虚假的夏季持续1～2分钟当幼儿园孩子们在阳光照射不到的Lovozero沐浴在紫外线之时。

A lightweight and oil-free sunscreen, bliss oil-free sunban lotion for the face with spf 30 offers broad-spectrum protection from harmful UVA and UVB rays.

一款轻薄无油的防晒乳液，必列斯面部防晒乳液提供用途广泛的保护，使皮肤免受紫外线伤害。

Moreover, the incidence of solar flares and the flux of solar cosmic rays, ultraviolet radiation and x-radiation all vary directly with the sunspot cycle.

此外，太阳耀斑的入射和太阳宇宙射线的流量，紫外线和x光线都直接随着太阳黑子的周期而变化。

In order to find new kinds of antibacterial agents, a primary screening model has been set with the DNA gyrase B subunit as a target, and then the active compounds of positive strain were purified. From Mycobacterium phlei, we isolated a novobiocin supersensitive mutant M.phlei SS12 and a resistant ~mutant M.phlei RR11 with NTG and UV.

实验采用Mycobacteriumphlei为出发菌株，利用NTG和紫外线复合诱变得到新生霉素特异性的超敏菌株M.phleiSS12和耐药菌株M.phleiRR11，建立了以DNA回旋酶B亚基为靶点的抗结核药物的筛选模型；并应用此模型对1600株真菌和100株放线菌发酵液进行了初筛，获得了38株阳性菌，阳性率为2.4%；对阳性菌株3277的发酵液进行了提取分离，得到X1和X2两个活性化合物。

Therefore the remaining UVA energy is the primary target of window manufacturers, and also the spectrum measured by all of EDTM's UV test equipment.

因此没被阻挡的 UVA 能量是窗户制造商的首要目标，也是所有 EDTM 紫外线测试设备量测出的光谱。

Minimum erythema dose was measured at each testee's upper arms.

根据受试者的最小红斑量，在三组人群的另一侧上臂内侧分别给予1.5倍MED、2倍MED、2.5倍MED剂量的紫外线照射，一周后肉眼观察判断红斑消退情况、黑素强度、黑素均匀度及表面光滑程度等情况，在照射前及照射后的第1、2、3、4、5周分别用CM2500分光测色仪及Mexameter18红斑黑素测量仪采集数据L、a、b、M、E值。

Either two thymine bases are lined up in just the right way to bond when the UV hits, or they're not.

当受到紫外线伤害的时候，胸腺嘧啶或者线性排列以正确的方式形成键或者不产生键。

The important damage type of DNA in cell, the thymine photodimerization, was studied.

本论文中我们欲探讨生物细胞中重要遗传信息携带分子- DNA -受紫外线照射时导致之常见损坏结构-胸腺嘧啶二聚体-的可能形成过程。

Objective To investigate the effect of TMP on melanogenesis of melanocytes induced by different dosages of UVB.

目的：研究川芎嗪对不同剂量中波紫外线诱导正常人黑素细胞黑素合成的影响，并初步探讨其机理。

Class sunroof and stern port are equipped with special suntan class to release passenger from ultraviolet radiation and torridity.

玻璃天窗和尾门配备了特殊的防晒玻璃，在艳阳高照时也可保护乘员免受紫外线幅射和过热的困扰。

KATHERINA. What is your sir, that you send for me?

凯瑟丽娜：夫君，您叫我出来有什么事？
