And by taking advantage of the redundance of several models, the reliability of complex system fault prediction can be improved.

本文介绍了数据融合技术的起源、发展、应用背景和常用的融合算法，重点阐述了运用贝叶斯算法和自适应加权算法实现多模型故障预报的方法。

While in Sect. Uniflos, leaf epidermal cells are usually irregular in shape, repand or sinuous in pattern of anticlinal wall, the stomata are anomocytic, and staurocytic, tetracytic, isotricytic besides.

植物叶表皮细胞常不规则型，垂周壁多浅波状，气孔除无规则型外还兼有十字型、四分体型和等三体型。

This paper introduces eight methods of tlme-frequency analysis, such as Hilbert transform, Hilbert-Huang transform, sine curve fitting, Ricker wavelet matching, short time Fourier transform, wavelet transform, S transform and Cohen methods, This paper explains the merits and defects of those methods from the time resolution, frequency resolution and the adaptive ability of multi-frequency signals.

本文介绍了Hilbert变换、Hilbert—Huang变换、正弦曲线拟合、雷克子波匹配、短时傅立叶变换、小波变换、S变换以及Cohen娄这八种方法，并从时间分辨率、频率分辨率，以及对多频率成份信号适应能力等各方面阐述了各种方法的优缺点，对其中的一些方法结合了理论记录进行了试算，进一步阐述了这些方法的长处和不足之处。

Basal leaves petiolate, rosulate or not, simple, entire or variously pinnately dissected.

具叶柄，莲座状的基生叶与否，单，全缘的或各种地回羽状多裂。

Hodges saw his shot to lift his fleshy, leafless shrub from obscurity. That's because salicornia has another nifty quality: It can be converted into biofuel.

何吉斯总算可以放手一搏，打响他那默默无闻多肉无叶的灌木，因为盐角草属有另一个极好的特质：它可以转化为生质燃料。

Lower leaves alternate, much smaller or scalelike.

茎直立 下部叶交替，小得多的或。

Influenced by strong wind of northeastern monsoon, the crest line and mountaintop are mostly covered by the windward dwarf sclerophyllous forest except for some early-seral grassland.

在研究区域内，因冬季受东北季风的影响，稜线及山顶部分的植群除了演替早期的草原外，多为受风冲影响的硬叶矮林。

The embryogenic cell first divided into multicellular proembryos,then globular embryoid,pearshaped embryoid,long embryoid,scutiform embryoid and mature embryoid.

胚性细胞继续分裂形成多细胞原胚，经球形胚、梨形胚、长形胚、子叶分化期到成熟胚，其发生的胚状体与单子叶合子胚形成具有相似的过程。

Leaves usually few, along stem, opposite, seldom alternate, equal to subequal in a pair; leaf blade surfaces sericeous to hirsute or woolly, often glabrescent, base attenuate to rounded.

很少的叶通常，沿茎，对生，很少互生，成对的等长到近等长；在多毛或具绵毛，通常被绢毛的叶片表面，基部渐狭到圆形。

In the negative and interrogative forms, of course, this is identical to the non-emphatic forms.

。但是，在否定句或疑问句里，这种带有"do"的方法表达的效果却没有什么强调的意思。

Go down on one's knees;kneel down

屈膝跪下。。。下跪祈祷
