查询词典 pre reduction

In particular,the C-Autoencoder provides such a bi-directional mapping between the high-dimensional data space and the low-dimensional manifold space and is not only able to overcome the inherited deficiency of most nonlinear dimensionality reduction methods that do not have an inverse mapping but also especially suitable for dimensionality reduction and reconstruction of high-dimensional continuous data.

特别地，这种连续自编码网络可以提供高维连续数据空间和低维嵌套结构的双向映射，不仅有效解决了大多数非线性降维方法所不具备的逆向映射问题，而且特别适用于高维连续数据的降维和重构。

In chapter five, we introduce the new nonlinear dimension reduction method: LTSA in dealing with the difficulty of analyzing high-dimensional, nonlinear microarray data. It's different from the commonly used linear dimension reduction methods.

与使用常规的线性降维方法对基因表达谱进行降维不同，针对处理高维非线性基因芯片数据的困难，本文引入了一种新的非线性降维方法LTSA。

Then the chemical reduction of[Ni(N_2H_4)_x]~(2+) may occur along the magnetic line of force due to the enhanced electrode potential,leading to the formation of uniform 1 D wires.While with the increase of the concentration of Ni~(2+), the reaction rate increases too,so it can be deduced that the chemical reduction of [Ni(N_2H_4)_x]~(2+) may be taken place quickly in the whole system,leading to the formation of isolated particles coexisted with the wires composed of microspheres which formed along the magnetic line of force.

而当Ni~(2+)浓度较高时，反应速率相对较快，[Ni(N_2H_4)_x]~(2+)可能在还没来得及迁移到磁力线之前，还原反应就已经很快的在整个体系中发生了，导致出现了产物中纳米球和一维镍线共存的现象。

However increasing the hypoid offset results in reduction of mechanical efficiency and a consequent reduction in fuel economy.

但是增加的机械效率和燃油经济性降低准双曲面相应减少抵消的结果。

At the low reduction temperature, copper species on the catalyst's surface were mainly zero valence copper and monovalence copper; at high reduction temperature, the copper species was mainly zero valence copper.

还原温度为300℃时，催化剂表面Cu物种主要以零价Cu的形式存在。

The true benefit of Tree of Life form, which seems to go almost unnoticed, is the 20% reduction in mana costs, most notably to Lifebloom which the 9% reduction offered by the Moonglow talent does not cover.

而这一形态真正的增益，20%法力消耗降低，却似乎被人忽略了。这一效果对生命绽放效果最为显著，可不是月光天赋所能比的。

Experimental results show that the different substituted location and different substituted group on benzene cycle would result in the diversity of reduction properties of substituted aryl nitrobenzene. Substituted nitrobenzenes with withdrawing group will be reduced at more positive potential, while those with repelling group will be reduced at more negative potential. In addition, the reduction potential of nitro group of o-nitrobenzene shifts more negative due to the effect of space resistance.

结果表明，芳族硝基化合物在苯环上的取代基位置不同以及在相同位置上取代基的种类不同均可使各芳族硝基化合物的电还原性能发生较大差异：吸电子取代基在电还原过程中电位较正，推电子取代基的电还原电位较负：邻位取代基在反应过程中由于空间位阻效应，苯环上的硝基在电还原时电位往负方向移动。

The reduction could be interpreted as showing individual impulse, large non-industrial capital as a result of representing the will of more concern, the reduction of mass destruction even greater action.

减少可以解释为表现了一个代表更令人关注的，大规模杀伤性更大的行动而减少个人的冲动，大非产业资本。

This paper designs the communication system of radio telescope FAST.

针对500m口径球面射电望远镜FAST分布式控制系统的特点完成了其通信系统的设计。
