查询词典 gases

And we used them into the inspection of these polluted gases. We used them because the constringent speed of wavelet neural network is very fast, they are not sensitive to the inputs of the network and they have the characteristic that they also can effectively approach the functions or signals. Classical neural networks mostly train the network with back propagation algorithm.

在目前常用的一维小波神经网络的基础上，我们研究了用来处理多维数据信息的小波神经网络，并将其应用于室内混合气体检测，主要是基于小波神经网络学习收敛速度较快，对网络输入不是很敏感，以及小波神经网络可以有效的进行函数逼近或者信号逼近的特点。

But the back propagation algorithm often gets into the minimum value and its constringent speed is slow. Aim at the gases, we design a optimum back propagation algorithm.

传统的前馈神经网络多采用误差反传学习算法对网络进行训练，但是误差反传学习算法具有容易陷入局部极小值，收敛速度慢以及容易导致震荡等缺点。

These catalysts can be used to eliminate toxic and contaminative gases.

此催化剂可用于消除有毒和有机污染气体

With the development of industry, loss of gas pollution has threatenedhuman beings badly. The key to solve these problems is to detect thosepoisonous and contaminative gases, development of gas sensor is justaccording to this.

在工业高度发达的今天，气体污染所带来的损失已经严重威胁到人类的生存，解决问题的关键是迅速准确的检测到这些有毒、有污染的气体，这便是气敏传感器发展的客观依据。

It was demonstrated that when 0.10molL〓HCl was used as internal electrolyte, higher sensitivity and lower detection limit were obtained, and other copresent gases, such as CO, NO, NH〓 and CO〓, hardly had effect on responses of SO〓.

结果表明，以0.10molL〓HCl作为内充电解液，将此气体传感器用于测定二氧化硫，得到的检测限较低，且CO，NO，NH〓和CO〓等共存气体对二氧化硫的测定几乎没有影响。

Many poisonous gases also have other hazardous properties, for example, corrosivity and flammability.

许多有毒气体还有其它的危险性质，例如腐蚀性和易燃性。

Many poisonous gases also have other hazardous properties, for example, corrosivity

许多有毒气体还有其它的危险性质，例如腐蚀性和易燃性。

Based on 65 days indoor incubation, potential emissions of three greenhouse gases CO2, CH4, and N2O from pot soils which were under Acmera acuminatisima Schima superba and Cryptocarya concinna seedling and caught in acid rain for 42 months were studied.

通过对土壤65d的室内培养，比较研究了种上荷木、肖蒲桃和黄果厚壳桂幼苗并受模拟酸雨淋洗42月的盆栽土壤温室气体CO2、CH4、N2O排放的差异。

Conducted on the environmental wind tunnel. The effects of the gas spill angle, the densimetric Froude number and the terrain parameter on the heavy gases diffusion are measured and investigated.

藉由实验量测重质气体之扩散浓度，以探讨当重质气体在各种溢漏角度、密度福禄数及地形条件下对於重质气体扩散之影响特性。

The results show that SO2 gas itself does not influence the growth of ZY-1, however, when the SO2 concentration is higher than 50×10^(-6), ZY-1 growth rate and its CO2 fixation rate are all lowered and the pH of the medium is decreased, so measures must be taken to desulphurize or control pH of medium temporality. The presence of NO with concentrations of lower than 300×10^(-6)did not influence the growth of ZY-1 and its CO2 fixation, NO absorbed in the medium is utilized as a nitrogen source. The influence of dissolved soot dust on ZY-1 growth and its CO2 fixation could be ignored once the soot dust in the stack gases was disposed by the original method.

结果表明，烟气中的SO2是以增加培养液中的SO2^(-2)浓度及降低pH的形式来影响ZY-1的生长及其对CO2的固定的，当其浓度大于50×10^(-6)时，需要进行烟气脱硫或控制培养液pH变化来消除其影响；烟气中NO浓度不高于300×10^(-6)时，不影响ZY-1的生长及其对CO2的固定，反而可作为氮源供ZY-1生长用；对经过一般除尘处理的烟气来说，在利用小球藻ZY-1固定CO2时可不考虑溶解性烟尘的影响。

This one mode pays close attention to network credence foundation of the businessman very much.

这一模式非常关注商人的网络信用基础。

Cell morphology of bacterial ghost of Pasteurella multocida was observed by scanning electron microscopy and inactivation ratio was estimated by CFU analysi.

扫描电镜观察多杀性巴氏杆菌细菌幽灵和菌落形成单位评价遗传灭活率。
