Multiple linear regression is the simplest way to build the relationship between the several explanatory variables and response variable. However, MLR often causes the estimated regression coefficients unstable or even unaccessible when the number of explanatory variables is more than that of objects. Especially, the explanatory variables are highly intercorrelated which called multi-collinear data. Therefore, many methods have been developed to analyze multi-collinear data, such as variable selection methods, ridge regression, principal components regression and partial least squares regression.

当要同时建立多个解释变数与反应变数间的关系时，最简单的方式是以复回归来处理，但是当解释变数数目远多於样本数，或者变数之间具有高度相关性时，会使得回归系数的估计变得不稳定甚至无法求得，这样的资料又称为共线性资料，在面临这样的资料时可以利用变数选取的方式降低资料组的维度，或者以脊回归、主成分回归及净最小平方回归等方法来灭种共线性的干扰。

First, by taking into account not only interband effects but also intraband effects, such as carrier heating , spectral hole burning , two-photon absorption and ultrafast nonlinear refraction and the interaction of control pulse and signal pulse in SOA, the relationship between the performance of TOAD (including flatness of switching window, chirp of output signal and extinction ratio of the demultiplexed signal) and the parameters of input pulse (including the wavelength and power of control and signal pulse) are studied.

首先，在考虑到由于带内效应，诸如载流子热效应、谱烧孔效应、超快非线性折射效应和双光子吸收效应而导致得非线性增益压缩效应以及控制光和信号光相互作用情况下，研究了TOAD的各性能参数，包括开关窗口的平坦性、输出信号的啁啾特性、解复用信号的消光比特性等与输入控制光和信号光的波长及功率的关系，在此基础上对TOAD性能进行了优化。

The approximate calculating method is proposed for the low loss and thin flake material perturbation outside of the cavity. The measured complex permittivities of teflon,polyvinyl chloride ,pure ceramic flake are in good agreements with the standard data.

在隙缝辐射较小的条件下，提出适于损耗小，厚度薄(1mm左右)的片状材料腔外微扰的近似计算方法，测得聚四氟乙烯、聚氯乙烯、纯陶瓷片等复介电常数与准确值相当吻合的结果。

It is shown from the study that influence of co-use anionic and nonionic surfactants on the enzyme activity are less than single anionic surfactant Multi-component stabilizers are much better than single-component stabilizers for enzyme activity.

研究结果表明：阴离子表面活性剂与非离子或另一种阴离子表面活性剂复配后，对酶活性的影响明显小于单一阴离子表面活性剂的影响。多组分稳定剂比单组分稳定剂对改善酶的稳定作用好得多。

Dowland disowned A New Booke of Tabliture, calling his lute lessons "falce and unperfect",[23] while Holborne complained of "corrupt coppies" of his work being presented by a "meere stranger".

道兰否认了和新书琴谱有关系，声称书中他的鲁特琴教程&又假又不完整&。与此同时，霍尔本因为他的作品被改得&面目全非&而抱怨该书为&漏洞百出的复印品&。

Coli culture . The recombinant enzyme was purified, dialysed and renatured, and exhibited arginine esterase activity, thrombin activity and fibrinogen cleaving activity without being released from the fusion partner. In animal model the recombinant protein significantly reduced rat blood fibrinogen level and inhibited experimental thrombus formation in rabbit.

融合蛋白通过纯化、透析复性，在未经肠激酶切的情况下，即测得精氨酸酯酶活性、凝血酶活性及纤维蛋白原降解活性；动物实验表明重组蛋白能降低大鼠体内纤维蛋白原的含量和抑制家兔实验性血栓形成。

The internal door latches look more realistic all the time and the visors flip up on little silver mounting points.

内部的门闩始终变得更现实，而且复面倒转在小的银展开点上上面。

1引言在光纤通信系统中，随着基于1.55μm波段皮秒～亚皮秒范围的超短光脉冲的光时分复用系统的飞速发展，超短光脉冲的检测问题变得越来越重要了。

Yet almost everybody recognizes that the season's character transcends those familiar bracing days, crystal nights, bigger stars, vaulted skies, fluted twilights, harvest moons, frosted pumpkins and that riotous foliage that impels whole traffic jams of leaf freaks up into New England (even though Columnist Russell Baker has reminded them that "if you've seen 1 billion leaves, you've seen them all").

然而几乎每个人都认识季节的个性超越那些熟悉者宜人的每天，水晶的夜晚、较大的星、有圆顶的天空、笛声的曙光，秋分前后的满月，复着霜南瓜而且驱使叶的整个塞车的引起骚扰的树叶变得焦燥在进入新英格兰之内上面。
