【求助】翻译欧洲药典澄清度部分

When a suspension is viewed at right angles to the direction of the incident light, the system appears opalescent due to the reflection of light from the particles of the suspension (Tyndall effect）当与入射光垂直的方向观察悬浊液的时候，由于悬浊液粒子光的反射，系统会出现乳白色的光（丁达尔效应）。at right angles to 与......垂直
A certain portion of the light beam entering a turbid liquid is transmitted, another portion is absorbed and the remaining portion is scattered by the suspended particles. 一部分光束透过悬浊液被传播，另一部分被吸收，剩下的一部分被悬浮粒子散射
If measurement is made at 90° to the light beam, the light scattered by the suspended particles can be used for the determination of their concentration, provided the number and size of particles influencing the scattering remain constant.
如果检测是以呈90°的方向进行，由悬浮颗粒散射的光，可用于测定其浓度，假定样品的数量和粒子的大小对散射的影响保持不变。
The reference suspension must maintain a constant degree of turbidity and the sample and reference suspensions must be prepared under identical conditions. 参照悬浮液必须保持恒定的浊度且样品和参照悬浮液必须在同一条件下进行制备。
Nephelometric measurements are more reliable in low turbidity ranges, where there is a linear relationship between nephelometric turbidity unit (NTU) values and relative detector signals.当浊度单位值与相关检测信号之间有线性关系时，浊度的测量在低的浊度范围内更为可信。
As the degree of turbidity increases, not all the particles are exposed to the incident light and the scattered radiation of other particles is hindered on its way to the detector.由于浑浊程度的增加，并不是所有的粒子都显露出入射光，而且其他粒子的散射辐射在检测器方向受到阻碍。
The maximum nephelometric values at which reliable measurements can be made lie in the range of 1750-2000 NTU. Linearity must be demonstrated by constructing a calibration curve using at least 4 concentrations.最大浊度值的可信测量范围在1750-2000 NTU。线性必须通过使用至少由4个浓度建立的校准曲线校正。

有不同意见的欢迎指正哦，另外一段楼主还是先把自己翻译的贴上来我们一起边看边改吧
