用这种方法

Sometimes the linear principal component analysis works inadequately when the data are nonlinear. In this paper, a new nonlinear analytic method, principal curve component analysis (PC~2A) is proposed.

对线性数据，PCA能保证降维后信息损失最小；然而，对占多数的非线性数据，这种线性分析方法受到较大的限制，用它分析数据可能会造成大量信息丢失。

When this happens you must guide the compiler by adding some extra information in the form of characters associated with the literal value.

若发生这种情况，必须对编译器加以适当的"指导"。方法是用与字面值关联的字符形式加入一些额外的信息。

If we were to try burying our detectors in order to attenuate the surface waves, we would soon grow discouraged

如果企图用埋置检波器的方法来衰减面波，很快就会发现这种做法是徒劳的。

The influence removing with optical automatic gain control is put forward in the paper.

本文提出了用光学自动增益控制法来消除这种影响，在理论上对该方法进行了分析计算，并在实验中得到了验证。

Alkaline lipase Greasex 50L is one of the leather enzyme products of Novo Nordisk AS. After extensive control trials on pigskins, evaluating effects by degree of fat removal and qualities of result leather, we got1 Fat removal rate can be increased by 10%and leather qualities such as napping and softness can be improved by using Greasex 50L together with liming enzyme NUE 0.6 MPX2 Some surfactant together with Greasex 50L is good to fat removal, and the recommended ratio is 0.05%～0.1%∶13 The fat content in the skins is lower after treated with Greasex 50L,which also benefits the successive processes, such as bating, pickling and tanning. As a result, the leather qualities, such as fineness of grain, softness, napping and evenness of dyeing can be improved.

Greasex 50L是诺和诺德公司生产的碱性脂肪酶已在皮革工业中广泛使用，为了更好地应用这种酶制剂，我们对Greasex 50L在猪皮方面的应用条件进行了研究采用对比的方法，用脂肪去除率和皮革的质量作为评价标准，研究结果表明1适量的浸灰酶 NUE 0.6 MPX可使Greasex 50L的脱脂率增大，同时可改善皮革的起绒状况和革身柔软性2一定量的表面活性剂与Greasex 50L配合使用，有利于脂肪的去除，用量为平平加的0.05%～0.1%3 经Greasex 50L脱脂的裸皮在鞣制后油脂含量也较低，有利于后续工序进行，从而使成革粒面平细、革身柔软，臀部起绒得到改善，染色均匀性良好

In this paper we study the method of interpolation by radial basis functions in H~k(k ≥ 1) and give some error estimates. By means of such interpolation with a special kind of radial basis function, we construct a basis in H~k(k ≥ 1). Combined with the Galerkin method, this theory can be applied to solve boundary value problems for elliptic partial differential equations (such as the third boundary value problem for Poisson equation and the corresponding problem for the biharmonic equation), and some numerical experiments are also given.

本文从求解偏微分方程的角度出发，在被逼近函数u属于一般的Sobolev空间H~k(k≥1)的情形，引入了一种径向基函数插值方法，并建立了相应的误差估计；再利用这种插值性质，从一类特殊径向基函数出发构造Sobolev空间的一组基，针对Poisson方程第三类边值问题和重调和方程类似边值问题，为用无网格算法求解偏微分方程边值问题建立了相应的理论，并通过算例来验证了这一算法。

In these belt-tightening times, cost-conscious workouts at home and at the gym topped the list of fitness trends for this year in a survey, followed by shorter, more time-efficient regimens , such as boot camp and circuit training .

一项针对今年健身流行趋势的调查显示，在当下需要勒紧裤腰带过日子的时期，人们将在家和健身房用省钱的方法健身列为首选，其次是强力训练和循环训练这种更省时间的强化锻炼方式。

With this practical case, the paper addresses the building methods and principles of framework components.

重点结合此实例，阐述了框架构件的制作方法和原则，并展示这种较大粒度的可复用构件在特定应用领域的效益。

Mutations in 31 known genes and additional unidentified loci can produce Charcot–Marie–Tooth disease.

他们用全基因组测序的方法对一个家庭进行特殊的诊断，在这个家庭中，有四个兄弟姐妹患有腓骨肌萎缩症-一种末梢神经疾病。31个已知基因中的突变和额外未确定的位点能够导致这种疾病。

The new method can also be used to predict the cleavability of an oligopeptide by HTV-2 protease and it also yielded a very high rate of correct prediction for both the training and testing sets.

这种新方法也可以用来预测HTV-2蛋白水解酶寡肽的断裂，试测和实测中也得到了很高的预测率。

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。
