With a magnifying glass, the rays of the sun can be focused to set grass or paper on fire. 用一面放大镜可以凝聚太阳光,而点燃和纸张。
Just as you steady a magnifying glass on a single object, with the hot burning sun rays analogous to your desire, focus, power, energy, time, etc, you will make an impact. 仅仅是你坚定地拿着放大镜聚集在单个物体上,炙热的太阳光比作你的期望,聚集,力量,精力,时间等等.你会带来冲击。
Eyeglasses can correct vision because light changes speed when it passes from air to a glass or plastic lens; this causes the rays to bend. 眼镜可以校正视力是因为光从空气射入玻璃或塑料的镜片时速度会改变,于是光线就发生了弯折。
He was experimenting with currents of electricity inside empty glass tubes, a phenomenon known as cathode rays. 他是利用在真空玻璃管中的电流来做称为阴极射线现象的实验。
To correct chromatic aberration, two or more lenses, made of different kind of glass, are used together to bend the light rays in such a way that they come together on the image plane. 要矫正色差,可用两片或以上不同性质的玻璃,造成透镜。它把光线作不同程度的屈折而集中一起。
The damage caused by sun coming through glass can be so dramatic that, over time, the side of the face exposed to the rays can end up looking up to seven years older than the other. 太阳光穿过玻璃对皮肤造成的损害是如此巨大,以至于长时间对着光线的脸颊看起来要比另一半脸颊老7年之久。
Infrared Dryer, the auxiliary equipment to Auto glass printing machine, mainly applies in drying glasses after their printing by ultrared rays. 红外线烘干机为全自动玻璃印刷生产线配套设备、主要用于玻璃印刷后的红外线烘干。
Monte Carlo calculation of the efficiencies of the lead glass detectors for high-energy gamma rays 蒙特卡罗方法计算铅玻璃探测器对高能γ射线探测效率
In this paper, a model program has been established to investigate the amplified spontaneous emission ( ASE) in the Nd: glass disk amplifier with the Monte Carlo method and rays tracing. 编制了一套用蒙特卡罗方法计算钕玻璃片状放大器内自发辐射放大(ASE)的模拟计算程序,考虑了光线在两大表面不同入射角对反射率的影响。
The principle of measurement, choice of γ-ray source, response of lithium glass to γ-rays and mass attenuation coefficient of γ-rays for the material are discussed. 讨论了测量原理、γ源的选择、锂玻璃探头对γ射线的响应并测定了氯化球团料的γ射线质量衰减系数。
Preparation of pcl/ glass fibre and pcl/ carbon fibre composites by γ rays irradiation and their biodegradability 用辐射方法制备PCL/玻璃纤维布和PCL/碳纤维布复合材料以及它们的生物降解性研究
Surface of PP powder and short glass fiber is modified with Gamma rays preirradiation in solid state and coupling agents. 采用γ射线预辐照固相接枝和偶联剂分别对聚丙稀粉粒(PP)和玻璃纤维(GF)进行表面改性。
