文中还改进了由Gennaro R， Jarecki S， Krawczyk H和Rabin T提出的计算秘密值的倒数的协议，使其效率得到了提高。

This paper analyses and proves that the restoring saturation coefficient α of one dimension extra-saturation sediment discharge method and the modified coefficient K of the quasi-hydrostatic settlement method are reciprocals each other.

分析论证了一维超饱和输沙法恢复饱和系数α与准静水沉降法修正系数K互为倒数；在分析影响α值变化主要因素的基础上，建立了计算恢复饱和系数α的数学模型；通过误差验证分析和经过几年生产设计部门的使用情况证明，模型的研究思路正确，精度、可靠度均满足设计要求，可供生产设计单位使用。

The results showed that 206Pb/207Pb, 208Pb/204Pb and 206Pb/204Pb of soil samples were all remarkably correlated linearly with reciprocals of Pb concentration, and 206Pb/204Pb had a significant positive linear correlation with 208Pb/204Pb, which was consistent with binary mixing model.

结果表明，土壤样品206Pb/207Pb、 208Pb/204Pb和206Pb/204Pb与Pb浓度的倒数，206Pb/204Pb与208Pb/204Pb都呈显著的线性正相关关系，这些关系符合二元混合模型，由此可以推断土壤铅主要源于人为排放和土壤母质。

In the construction of grey pairwise comparison matrices, we propose three approaches, namely, to apply (1) the reciprocals,(2) the upper and lower bounds, and (3) the grey operators of the upper triangular matrices as the lower triangular elements.

结果显示以灰元素及其倒数建构灰成对比较矩阵时，层级要素相对重要性程度之排序结果，与经由分析阶层程序法所得之排序结果相近；但由灰元素之上下限构成灰成对比较矩阵所得的结果，则与经由分析阶层程序法所得之排序结果差异极大。

TRS utilizes this property and has three main characteristics:(1) zonal effluent cap is set by taking into account the water pollution loads transferred from the upstream zones;(2) the trading ratios are set equal to the reciprocals of the exogenous transfer coefficients among zones; and (3) permits are freely tradable among dischargers according to the trading ratios.

此交易比制度具备三项特性：(1)预先扣除上游下流之污染量，设定分区排放量上限；(2)交易比等於外生之转移系数的倒数；(3)污染源依据交易比，自由交易排放许可证。

Hopfield networks have learning capabilities; the circuit in this design idea can apply different adaptive-learning rules by using alternative comparator-inverter/comparator-follower schemes, conductance-node-layout schemes—reciprocals of the feedback resistances—between the input comparators, and bit-order readouts.

参考和模拟输入电压驱动神经网络，数字输出来源于网络中的比较器。hopfield网络具有学习能力；本设计方案的电路采用不同的自适应学习规则，通过使用可选的比较器-转换器/比较器-跟随器方案，电导节点规划方案——反馈电阻的倒数——在输入比较器之间，和位顺序读出器。

The ratio of the focal length of a lens or lens system to the effective diameter of its aperture.

屈光度透镜或棱镜折光率的一种量度，等于以米计算焦距之倒数

Note: Most mass spectrometers calculate the reciprocal of the above and state it as a percentage, which is equally valid.

注意：大多数质谱仪能够计算上面式子的倒数并且以百分比的形式表示出来，其实也是同样有意义的。

You can use an egg timer to countdown to fifteen minutes so that you're not constantly opening your eyes to see how much time has gone by.

你可以用倒数计时器设定十五分钟，这样就不用老是睁开眼睛去看过了多久时间了。

Cynanchum Lingtai apricot production in the average weight 65 grams, the brightly-colored fruit, juicy rich, sweet-sour taste, sweet from the nucleolus, when the late Qing Dynasty famous Shaanxi, Gansu provinces, the Qing imperial court Tongzhi tribute for years.

灵台生产的牛心杏平均单果重65克，果实色泽鲜艳，汁多味浓，甜酸适口，离核仁甜，清末时就驰名陕、甘两省，清同治年间曾为朝廷贡品。

Chenopodium album,Solanum nigrum, and Amaranthus retroflexus were very susceptible to the herbicides. Polygonum persicaria and Abutilon theophrasti were relatively less susceptible to the herbicides, and Lycopersicon esculentum was not susceptible to it. The relationship between reduction rates of weed biomass and PPM values of weed leaves 2,4, and 6 days after treatment was established.

供试的6种杂草对该混剂的敏感性存在显著差异：红心藜Chenopodium album、龙葵Solanum nigrum和反枝苋Amaranthus retroflexus对该混剂最敏感，ED90值分别为47.65、71.67和29.17g/hm2；春蓼Polygonum persicaria和苘麻Abutilon theophrasti敏感，ED90值分别为96.91、114.20g/hm2；而番茄不敏感。
