In addition,the athermal aberration design principles of singlet,doublet in contact and doublet spaced apart are also discussed in this paper.

最后根据上述分析，讨论了几种简单系统的热效应与无热象差设计途径

The 1H-NMR spectrum collected on a 200 MHz instrument had a doublet at a chemical shift of 5.88 parts per million which integrated to one proton, a multiplet at 4.19 ppm which integrated to one proton, a singlet at 2.5 ppm which integrated to six protons, a doublet at 1.60 ppm which integrated to three protons, and a broad peak at 0.8 ppm which integrated to two protons.

该核磁共振谱收集在一个200 MHz的仪器有一个双线在化学位移5.88百万分之的综合，以一质子， 1 multiplet在4.19 ppm的综合，以一质子，单在2.5 ppm的综合到6个质子， 1双在1.60 ppm的综合三个质子，和广阔的高峰期， 0.8 ppm的综合两个质子。

A two-proton multiplet at d5.00(2H,m,H-11)and a one-proton doublet doublet at d5.90 could be assigned to an ABC pattern.

一个两质子在d5.00(2H，m，H-11)的多重峰和一个单质子在d5.90 的双峰可以表明该分子是一个ABC的形式。

The duct and the wake of duct is also discreted by a number of small hyperboloidal quadrilateral panels. Constant source and doublet are distributed on duct while there are only doublet on wake of duct.

以面元的几何形心为控制点，在每个物面面元上布置等强度的源汇分布和偶极子分布，每个尾涡面面元上布置等强度的偶极子分布。

The PESes were discussed in detail. The results showed that the ground-state doublet state has lower energy barrier and is exoergic. Therefore, the reaction on the doublet PES is favorable.

结果表明在二重态势能面上的反应具有比较低的能垒，是一个放热反应，所以该反应更易于在二重态上进行。

By 1933 Zeiss had manufactured several proven refractors of the "E","A" and "AS" achromatic doublet designs, and apochromat triplets of the "U.V."

1933年，蔡司生产了"E"，"A"和"AS"等几款使用消色差镜头设计，并经过实际使用验证的折射望远镜，还有"U.V。"

The result was an air-spaced apochromatic doublet. Color correction was as good as or even exceeding most triplet systems and contrast was far superior.

采用空气分隔的复消色差双片设计出现了，对色差的纠正能力等于甚至超过了三片式的设计，对比度更胜一筹。

The new FS series employs fully hard over-coated fluorite and low dispersion elements in an air-spaced f/8 doublet design that provides the highest contrast, brightest, and sharpest images in an apochromatic refractor today.

新的FS系列使用了完全硬镀膜和低色散透镜，两片空气间隔的透镜f/8能提供最大的成像对比度、亮度和锐度。

A close-fitting, hip-length, collarless jacket having no sleeves but often extended shoulders, belted and worn over a doublet by men especially in the16th century.
