8，The OLIS DSM CD utilizes 100% of the
light from the measuring beam (a 150 watt Suprasil xenon arc lamp run with precision current
controlled power supply), resulting in 100% increase in light for detection than single beam CD
spectrophotometers.
双光束比单光数利用率高一倍，
9，The sample is simultaneously interrogated by left and right circularly polarized light when positioned in principle cuvette holder (designed for use with cylindrical cuvette of arbitrary pathlength, as well as 1 cm² cuvettes, and jacketed for coolant circulation).
左右圆偏振光同时检测样品
10，Dual Beam detection method results in zero drift and near-perfect baseline flatness, as well as
outstanding S/N quickly (e.g., 0.04 mdegs @ 185 nm during 10 minute scan of 225-175 nm).
双光束检测法导致零漂移、近乎完美的平坦的基线
噪音：0.04豪度@ 185 nm，175-225nm，10分钟扫描
11， All electronics and software are optimized for sensitivity and speed, including 16 bit 500 kHz twin
analog-to-digital card.

12，Instrument can also be used in a single beam mode, using secondary jacketed 1 cm² cuvette holders (two) which are provided for detection of two CD samples in single beam mode simultaneously, dual beam absorbance, and/or single beam fluorescence measurements.
同时适用于单光束模式，该模式下可用单光束同时测量两个圆二色样品。还可用于双光束吸收和/或单光束荧光检测
13，Fully digital design means that all sorting, all summing, all ratioing, all logarithms, all noise filtering, et cetera, is done by the highly sophisticated OLIS CD SpectralWorks System, software designed for providing maximize flexibility in operation to fully exploit capabilities of this dual beam CD spectrophotometer and data handling of this dual beam CD spectrophotometer and accessories used with it.
完全数字化设计，所有操作都可以在OLIS CD SpectralWorks系统上实现。
14，Included in the comprehensive data
acquisition/analysis/instrument control software package are the OLIS Global Fitting
algorithms, using SVD, Downhill Simplex, and Matrix Exponentiation for 3D data analysis; as
well as the four widely used logarithms for secondary structure determination- SELCON3,
CONTINLL, and VARSLC- and an exhaustive selection of 2D data manipulation choices
(smoothing, derivatives, exponentials, subtraction, etc.).
全面数据采集/分析/仪器控制软件包—— OLIS Global Fitting algorithms,，利用奇异值分解，单纯形和矩阵幂用于三维数据分析；
