慢性暴露中，对孵化时间影响的最低可观察效应浓度LOEC(下标 30d为0.1mgL^(-1)；暴露于0.4mgL^(-1)的高锰酸钾对30d后日本青鳉的体长、体重、累计死亡率均有显著影响，但对孵化率率无显著影响。

In chronic exposure, significant changes in length, weight and cumulative mortality rate of fish was observed at concentrations higher than 0.4mg·L-1, but no effect on hatchability.

慢性暴露中，对孵化时间影响的最低可观察效应浓度（LOEC30d）为0.1mg·L-1；暴露于0.4mg·L-1的高锰酸钾对30d后日本青鳉的体长、体重、累计死亡率均有显著影响，但对孵化率率无显著影响。

Using the indoor simulating method of pollution exposure at various concentrations,the toxic effects of various concentrations of petroleum hydrocarbons, copperCu~(2+ and cadmiumCd~(2+ on the polychaete Perinereis aibuhitensis Grube and on its acetycholinesterase activity were examined.

采用浓度梯度污染暴露室内模拟方法，研究了沙蚕暴露于不同浓度的石油烃和重金属Cu2+、Cd2+的毒性效应及乙酰胆碱酯酶活性的响应。

Methods : We subjected C57BL/6J mice to CS (whole body exposure, 90 min/day) for various periods, and used laser capture microdissection to isolate bronchiolar epithelial cells for analysis of mRNA by quantitative reverse transcription-polymerase chain reaction.

研究方法：研究者将 C57BL/6J 小鼠分别在不同时间周期暴露于CS（全身暴露，90分钟/天），用激光捕获显微切割技术分离细支气管上皮细胞，然后用定量逆转录多聚酶链反应分析上皮细胞的mRNA。

Results Inbreathe and dermal exposure to THMs in reclaimed water were the main ways of exposure for occupational worker and general populations in road clearing and public garden virescence in Beijing.

结果 再生水中氯仿、一溴二氯甲烷、二溴一氯甲烷、三溴甲烷的浓度分别为0.875~108、0.06~11.0、未检出～5.82、未检出～3.04μg/L。再生水回用于道路压尘、公园绿化，人群通过吸人和皮肤两种途径暴露于再生水，吸人暴露为主要途径，其消毒副产物THMS中。

The effects on hepatic EROD(7-ethoxyresorufin O-deethylase)in Mugil so-iuy exposed to benzo pyrene,pyrene and their mixtures of equal concentration were investigated,at concentrations of 0.1,1.0,5.0,10.0,50.0μg/dm^3m,in experimental condition.

为测定真鲷胚胎CYP1A活性（ethoxyresorufin-o-deethylase，EROD）对于BaP暴露的响应，将受精两天后的真鲷胚胎暴露于不同浓度的BaP（0.5，0.8，1.2，1.8μg/L），采用一种对胚胎个体无损伤的方法测定胚胎EROD活性。

Moreover, patient histories may identify common patterns of illness among individuals with a common lifestyle or exposure element, such as reproductive problems in individuals occupationally exposed to lead.

甚至，通过病史询问可以从个体共同的生活方式或暴露元素中确定共同的疾病表现模式，如生殖问题通常是因职业暴露于铅元素中所致。

Exposure of naive CD4〓T lymphocytes to superantigen induces a strong proliferative response. Prolonged exposure or subsequent restimulation of the responding CD4〓T cell population with superantigen leads to the apoptotic events of activation-induced cell death.

幼稚的〓细胞暴露于超抗原可诱导强烈的增殖反应，继续延长暴露或再次刺激应答〓细胞可导致活化诱导的细胞死亡。

Sequence of events in remodeling using three commonly used mouse models of allergic airways disease in which mice are exposed to nebulized ovalbumin for four consecutive days, seven consecutive days, or three times a week for 6 wk.

我们利用三种常用的变应性气道疾病的大鼠模型来观察重构的序列事件，老鼠暴露于雾化卵白蛋白连续四天，暴露七天，或者一周三次共六周。

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。

The basic concept of FOP can be summarized as to further optimize effective prescription according to the standard of curative effects and with the aid of modern science and technology and theories of traditional Chinese medicine.

其基本内涵可概括为：以确有疗效的中药复方为研究对象，以现代科学技术和传统中医药理论为技术支持，以该复方所治病证的药效响应为评价标准，以优化重组疗效更优的新复方为研究目的。

Ever since our world has been a world, native forests have been indiscriminately exploited by man.

自从我们的世界一直是世界原生森林被任意剥削人。
