查询词典 x-rays

"The effects of some mutagens are increased or suppressed in some organisms by the presence of certain other, nonmutagenic substances; oxygen, for example, makes cells more sensitive to the mutagenic effects of X rays."

有机体内某些非诱变物质的存在，可以加强或抑制一些诱变因子的作用，例如氧可使细胞对X光的诱变作用更加敏感。

Basing on the Monte-Carlo calculations of the detectors'responses to radiation and n/γdiscrimination ability, their radiation response properties are experimentally investigated on pulsedγrays, X rays from Z-pinch processes, n/X mixed radiation fields of the DPF neutron generator, electron beams of BEPC II Testing Beam Facility.

完成了探测器辐射响应、n/γ分辨能力的蒙特卡罗模拟计算，开展了探测器对脉冲γ射线、Z-pinch过程脉冲X射线、DPF装置脉冲中子/X射线混合场、BEPC II试验束装置脉冲电子束及国家串列加速器脉冲质子束的辐射响应实验研究。

Boehmeriae were studied, and the results indicated that the zoospores of P. boehmeriae could be inactivated obviously by irradiating with 30W ultraviolet light 50cm away from the culture dishes tested and that 95% germination of zoospores could be restrained by 30W ultraviolet light treatment for 40sec.The mycelium growth from mycelium discs of P. boehmeriae were inhibited mostly by 30W ultraviolet light treatment for 20min. Afterwards, the inhibitive rates were decreased with the rise of the treatment time, which showed that the mycelium discs of P. boehmeriae had produced flexibility to ultraviolet rays after being irradiated by certain dosage of ultraviolet light.

研究了紫外光对苎麻疫霉生物学特性的影响，结果表明，30W的紫外灯管距培养皿50cm照射处理对苎麻疫霉的游动孢子具有明显杀灭作用，紫外光照射40sec可以抑制95%的游动孢子萌发；紫外光照射20min对菌丝块的菌丝生长的抑制率达最大，以后随着处理时间增加，抑制率却有降低的趋势，说明苎麻疫霉的菌丝块，经一定剂量紫外光照射后对紫外线产生了适应性。

Vignetting can occur due to the altered ray path, when the eyepiece's lenses are not large enough in diameter to allow all the rays to make it through.

装饰图案可以发生是由于蚀变射线路径，当目镜的镜头是不是足够大的直径，让所有的光线，使之通过。

Ionizing radiation (such as X-rays) contains sufficient energy to knock electrons out of their valiances, thereby creating chemically active ions.

电离 辐射载有足够的能量来敲门电子离开自己的valiances ，从而产生化学活性离子。

You may need X-rays or an ultrasound to check the kidneys and ureters.

您可能需要X光或超音波检查肾脏和输尿管。

Rays unequal; bracteoles subequal or shorter than umbellules.
