height of eye
observation height
observed altitude
Examples
- The number of cascade particles changes according to the incident cosmic ray energy , observation height , etc
到达地面的簇射粒子数目会随不同因素而改变，包括原初宇宙射线的能量、观测高度等。 - If the focal point of the len shifts around the surface of the sample , the mass ablation , the temperature of the plasma and the spectral intensity appear asymmetric and their maximum occur at the location which is about 0 . 4mm under the surface of the sample . ( 2 ) to the plasma of the aluminum alloy sample , when the operating voltage is 1600v , the height from the observed location of the plasma to the surface of the sample is 2mm and the argon pressure is 660 torr , the spectral intensity have the maximum values
( 2 )对于标准铝样品，在激光器工作电压为1600v 、等离子体观测高度为2mm 、氩气压力为660乇时，其谱线强度最强；以al 308 . 22nm 、 al 309 . 27nm两条谱线为分析线，发现随着环境气压的增大，谱线自吸效应明显增强，当环境气压达到600 - 700乇时，谱线几乎产生自蚀。 - Besides , the information on actual height of lowest cloud base is used in constructing of cloud liquid water profile by using radiosonde profiles , that makes an improvement of relative accuracy of retrieved value of l at almost all altitudes by 5 - 20 % according to numerical simulation comparison . the lower the altitude is , the more the accuracy is improved
为减少由于回归样本中云液水廓线的‘失真’给反演造成的误差，本文在对探空廓线作诊断建立云液水廓线时，引入了实际目测的最低云底高的信息。数值模拟比较表明该措施行之有效，使对流层中下层的几乎所有高度上l反演值的精度提高5 - 20 ，观测高度越低，精度提高越多。 - In this experiment , a neodymium glass laser is used to study the effects of the operating voltage , power density , the height from the observed location of the plasma to the surface of the sample , the location of the sample , the gas composition and the pressure on the intensity and quality of the spectrum
