难以控制

In announcing the agreement to reporters from the United States, President Obama acknowledged that it falls short of what the science demands in order to hold global warming to roughly 2 degrees Celsius over preindustrial levels.

在向来自联合国的记者宣布该项声明时，奥巴马总统承认，为在工业化时代将全球变暖幅度控制在大约摄氏2度，该项协议还难以达到要求。

The exertion and implementation of the effectiveness of the criminal policy of coordinating benevolence and stringency relies on a perfect mechanism involving the cooperation of legislation, justice, execution and social control, without which the proleptic effect will not be reached.

宽严相济刑事政策效用的发挥和实现，有赖于完善的立法、司法、行刑和社会控制机制，没有各个方面的支持和配合，将难以发挥预期的作用。

For example,many problems exist in the rural health system.,such as the resourcelessness of the rural health system,and the difficult to supervise and control the supply side's behaviors of medical service effectively.

但是与此同时，我国的改革也面临着许多困境，比如我国农村医疗卫生体系就存在农村医疗卫生体系资源不足以及难以有效监督和控制医疗服务供给方的行为等问题。

She had been laid up with a knee injury for severy days,and the time alone at home certainly was not helping, her misery was only compounded by her frustration at herself for not being able to pull it together and stop crying all the time.

几年前，唐娜一直委靡不振，那时和她相恋两年的男朋友刚刚分手，这让她难以承受，接着她又因膝盖受伤卧床数日，当然孤独在家的日子对她的身心毫无益处，她无法控制这种局面，因而，痛苦不尴，整天懊恼，伤心，泪流满面。

Neither PID steer nor adaptive steer shares the character flaws, which results in unassuring effects.

但它们由于各种原因存在着这样或那样的缺点，使得控制效果难以保证。

In degraded PSM matching classification, errors modification method of degraded PSM is presented and the matching tensor of every canonical scattering centers is given. In Chapter 4, the theory of wideband millimeter-wave radar target identification is introduced. It is indicated that, for HR radar target identification, description of temoral relations among features and pattern recogntion adaptive to variation of target angles are of key importance. A rule-based pattern recogniton method of sequential reasoning is proposed, which uses a series of rules to describe relations of features variation caused by target angles variation and has the advantages of adaption to unrandom variation and false probability control in classification over traditional statistical pattern recognitiop method. Feature extraction is crucial step in target identification. In range profiles identification application, features are extracted by means of range domain pre-processing algorithm, spacial and amplitude visual computation directly from range profiles and transform algorithm based on range profiles. Visual or transformed features are either sufficiently convinced or necessarily convinced and both of them are effective and robust to range profiles identification.

在第四章，首先对宽带毫米波体制背景下目标识别方法的一些特点进行了阐述并指出，在毫米波雷达目标识别中，特征之间动态关系的描述以及能适应目标姿态角变化的模式识别方法的研究乃是要解决的关键问题；进而提出了一种基于规则库的序贯推理模式识别新方法，在这种方法的研究中，主要包括序贯推理规则库的规则排列与特征选用顺序以及规则库的收敛等问题；这种方法克服了传统的统计模式识别方法特征利用效率不高、难以适应特征值的非随机性变化的缺点，把姿态角变化所引起的特征的变化用一系列规则加以表示，其优点是能适应特征值的非随机性动态变化，并能控制分类过程中的差错概率α；特征抽取是目标识别中的关键步骤，在基于目标距离像的特征抽取方法研究中，提出了距离空间域的预处理算法、距离空间域与幅度域的直观特征抽取方法以及基于目标距离像变换分析的特征抽取方法。

This is a difficult concept for some, as they have a hard time relinquishing control and allowing other healers to do their job.

这是一个难以理解的概念为一些，因为他们有困难的时候放弃控制，允许其他疗愈者来完成他们的工作。

Women also face many social and emotional challenges, which can lead them to become a slave to the scale, avoid exercise for fear of bulking up and fall for spot reduction and quick fix solutions, all of which only compound the problem,婷美上海婷美实体专卖店,郑州婷美专卖店, These fears, misconceptions and bugaboos, which hold so many women hostage, could easily fill a book, but let's skip over all that and talk about solutions that DO work.

女性经常面对来自社会和感情方面的困扰从某种程度上说这使得她们更难以摆脱如同奴隶的命运般的困境她们畏惧体育锻炼她们担心这些体育活动会使她们的腿部变粗胸部变小因而她们倾向于寻找快速而容易的塑身手段然而这将带来更多的问题恐惧误解以及如同幽灵一般的错误认识就象挟持人质的案犯一般控制了女性的思想和行为这几乎可以写成一本完整的书籍让我们揭开它们的面具还原它们的真实面目下文将重点讨论解决方案以及从现在开始改变对就是从现在。

So, too, the mind which is dammed and controlled, trained constantly, will be of immeasurable benefit.

同样的，一颗被&筑堤&控制、经常训练的心，将会获得难以计量的利益。

If the use of decentralized, local control, monitoring and measurement is difficult to imagine.

如果采用分散管理，就地控制、监视和测量是难以想象的。

With Death guitarist Schuldiner adopting vocal duties, the band made a major impact on the scene.

But he could still end up breakfasting on Swiss-government issue muesli because all six are accused of nicking around 45 million pounds they should have paid to FIFA.

不过他最后仍有可能沦为瑞士政府&议事餐桌&上的一道早餐，因为这所有六个人都被指控把本应支付给国际足联的大约4500万英镑骗了个精光。
