People with fair skin and blue eyes who burn easily stand the highest risk.

浅肤色、蓝眼睛的人会轻易就被晒黑，因此他们患皮肤癌的风险就高。

Cancer is uv's final result.shortwave radiant energy,especially from the uv b band,breaks the strandsof dna.enzymeswork constantly trearrange the dna into proper sequence.but with repeated uv exposure,the repair process may even-tually break down.then the mutantdna may produce a colony of cancer cells.but skin cancer may be avoided with a good dose of common sense.people with fair skin and blue eyes who burn easily stand the highest risk.special danger spots are the parts of the body most constantly exposed to the sun,such as the cheeks,nose,lower lip and the ears.people who have already developed precancerouslesionsor had one skin-cancer growth stand a greatly increased chance of developing others.

紫外线伤害的最终结果就是诱发癌症。短波辐射能量，特别是来自uv-b波段的辐射能量会破坏dna链。本来，酶能够按照适当的顺序来重新安排这些被打乱秩序的dna，但是持续暴露于紫外线下会让这一修复过程崩溃。到那时，变异的dna就会制造出大量的癌细胞。其实，只要运用一些常识。我们就能预防皮肤癌。浅肤色、蓝眼睛的人会轻易就被晒黑，因此他们患皮肤癌的风险就高。诸如脸颊、鼻子、下嘴唇和耳朵等长期暴露在阳光下的部位是皮肤癌的高发区域。那些已经受到癌症前期伤害或者是已经患过一次皮肤癌的人，极有可能再次患上皮肤癌。

TiO2 photocatalyst which was doped with Fe(superscript 3+), surface modified with H2SO4, whose single expension was improved by NH4Cl, was prepared using immersion method. Its degradation efficiency on direct fast black G under ultraviolet and sunlight was investigated.

采用浸渍法制备了掺杂Fe(上标 3+)，用NH4Cl提高单分散性并且用稀H2SO4表面修饰的TiO2粉体光催化剂，考察了它与TiO2在紫外光和日光作用下对直接耐晒黑G的降解效果。

Some of the most popular tanning lotions are those that contain an ingedient known as hemp seed oil.

一些最受欢迎的晒黑乳液是那些含有被称为ingedient大麻籽油。

Branchlets tan to red-brown, sometimes with corky wings, glabrous or sparsely pubescent when young, with scattered lenticels.

小枝晒黑到红棕色，有时具木栓质的翅，无毛或疏生短柔毛在幼时，带有星散皮孔。

If you are light-skinned, look for products marked for light to medium skin tones. Those marked dark work best on people with naturally darker complexions who tan easily.

如果你肤色较浅，寻找用于浅和中间肤色的产品，深色标识的产品适合皮肤较深容易晒黑的人。

她穿的是短群和低跟凉鞋，露出好看--不，应该说是漂亮、光滑、健美、被晒黑了的大腿。

The absorption and distribution of chromium were studied in ryeusing nutrient culture technique and pot experiment.

采用不同浓度K2CrO4(0，0.4，0.8和1.2 mmol/L)的Hoagland营养液处理黑麦幼苗，测定铬在黑麦体内的亚细胞分布、铬化学形态及不同部位的积累。

By analyzing theory foundation of mathematical morphology in the digital image processing, researching morphology arithmetic of the binary Image, discussing two basic forms for the least structure element: dilation and erosion.

通过分析数学形态学在图像中的理论基础，研究二值图像的形态分析算法，探讨最小结构元素的两种基本形态：膨胀和腐蚀；分析了数学形态学复杂算法的基本原理，把数学形态学的部分并行处理理念引入到家实际应用中。
