无法解决

Battista and Clements(1996, 1998) indicate that students are difficult to perspect and imagine the hiding cubes, or coordinate orthogonal views of cubes correctly.

Battista与Clements(1996， 1998)指出学童在解决立方体计数的问题时，无法对隐藏的立方体进行透视与想像，或无法正确协调柱体直角的视点，即使到了国小高年级，仍有一定比例的学生计数错误。

Many prominent U.S. financial figures, both in and out of government, have stated that our current-account deficits cannot persist. For instance, the minutes of the Federal Reserve Open Market Committee of June 29-30, 2004 say:"The staff noted that outsized external deficits could not be sustained indefinitely." But, despite the constant handwringing by luminaries, they offer no substantive suggestions to tame the burgeoning imbalance.

许多重量级的美国财经学者，不论是当政的或是在野的，都一再重申，目前的经常帐赤字绝非常态，举例来说，美国联邦准备公开市场操作委员会于 2004 年 6 月 29-30 日的会议记录中便提到，幕僚群已注意到我们绝对无法负荷长期大量的外部赤字，尽管一些重量级人物不断大声疾呼，但实际上他们还是无法提出彻底解决贸易赤字的具体方案。

Hereinto, the study of Multi-Agent simulation of economies based on the complex adaptive system theory is an important research branch of the complexity of economy.

首先，由于现实经济中涉及的因素众多，相互关系复杂，给数学方法的运用带来了一定困难；其次，传统方法没有很好地解决经济系统的层次性结构问题，因此，无法对不同层次的特性差异给予一个整体性的解释，也就产生了宏观、微观相互脱节的理论体系上的缺陷；再次，传统经济理论对现实经济普遍存在的信息不完备与不确定性尚不能给予系统的解释；最后，传统经济中以观测数据为基础的经验主义的研究方法，无法深入了解经济的微观运行过程，从而降低了理论对现实的解释与预测能力。

Qing-confucianism in this time solved the problem could not solved before that beef up the bandage of individual, prefer to instrumentality and defer to compatibility and appeal. Normativeness and constraint were its main orientation in the second period, but the theoretic outcomes of its prophase had been reserved.

这一时期的学者们只是在自身的范围内解决学术的"明体"与"适用"的问题，他们意识到了重整伦理秩序的紧迫性和重要性，但还无法将已有的理学思想资源整合成一套可供践行的思想样式，也就是说他们尚无法通过某种权威的力量来使他们所阐扬的伦理原则得到普遍的理解，他们只能以自身的实践来充当一个时代的典范。

In doing back-up data, we followed the work to be done is to switch to a system running DOS, and DOS command line in the implementation of "fdisk / mbr" command string to try to repair the hard disk of soft failure occurred ; if such a repair method to try is invalid, then we can go online to download and install the hard drive Bad Track professional testing tool to double-check the local hard disk in the phenomenon of the existence of Bad Track, Bad Track If you can not find the hard disk, it can not detect hard drive through the phenomenon is likely to be caused by the logic of failure, when the only thing we can use the way is hard to find the logic of the corresponding brand Bad Track Repair Repair Tool to re-click the hard disk, I believe that case the hard disk will be able to detect the phenomenon can not be resolved the.

在做好数据的备份工作后，我们接下来要做的工作就是将系统切换到 DOS 运行状态，并在 DOS 命令行中执行" fdisk /mbr "字符串命令，来尝试修复硬盘中发生的软故障；要是这种修复方法尝试无效的话，我们可以到网上下载安装一些专业的硬盘坏道检测工具，来仔细检查本地硬盘中是否存在坏道现象，如果找不到硬盘坏道的话，那硬盘检测无法通过的现象很可能是逻辑故障引起的，此时我们唯一可以使用的办法就是找到对应品牌硬盘的逻辑坏道修复工具来重新修复一下硬盘，相信这么一来硬盘检测无法通过现象就能被解决了。

Actually, the development of genetically-modified products is adouble-edged sword: On the one hand, it contributes to theenhancement of the world crop yield, as well as the quality, andreduction of chemical fertilizer and the pesticide use, helpssolution of the famine and undernourishment in developingcountries. Besides, it also promotes the development of certainrelated industries like pharmaceutical and chemical industries; Onthe other hand, it also brings the unprecedented threat for humanbeings. We are unaware of the potential effects in human bodies, orany unknown injury to the next generation, caused by geneticmodification. Nor can we forecast what kind of influence to theextant gene will emerge.

而事实上，转基因生物技术的确是一把双刃剑：一方面，转基因技术可以提高世界农作物产量、提高质量、减少化学肥料和杀虫剂的使用、解决发展中国家的粮食缺乏、饥饿和营养不良的问题，另外，基因技术的飞速发展在很大程度上也促进了医药、化工等相关行业的发展；另一方面，它也为整个人类带来了前所未有的威胁，人们无法得知基因序列的改变会在体内引起何种潜在的变化，无法确定转基因产品是否会对下一代产生任何未知的伤害，无法预测转基因产品对现存基因会产生何种影响。

UFJ financial holdings Inc. was also unable to deal with large bad debts and sought to merge with Mitsubishi-Tokyo financial group to solve the management crisis. MTFG longed for increasing the domestic and off-shore blanches to make more profits and catch up with American and European financial groups after solving bad debts problem and maintaining sound capital adequacy ratio.

UFJ金融控股集团则因为无法有效解决呆帐问题，而企图与体质健全的三菱东京金融集团合并，以解决其经营危机；三菱东京集团在解决呆帐问题、维持健全的资本适足率后，亟欲扩大国内外分行规模，转向追求高收益能力、以同欧美大型金融集团竞争。

At the same time, the cold and dry air has the effects of dehumidifying and ventilating.

利用井下作业所用高压空气作为膨胀工质，通过透平膨胀机等熵膨胀降温后送入独头掘进工作面，即可达到降温除湿的目的，又通过引入新风提高了空气含氧量，具有较好的局部降温通风效果，克服了单纯通风方法无法降温和一般机械制冷方法无法通风的缺点，有效解决深井平巷独头掘进工作面的局部高温热害问题。

ITD is adopted to get dynamic parameters of Bell Tower within traffic vibration amplitude for the first time,on this basis,the stiffness of mortise and tenon joint calculation model is derived through inversion,the questions of dynamic parameters unable to be identified with the traditional methods in environmental noise and the similar timber structure is unreasonably calculated due to tenon and mortise connection stiffness cannot be accurately determined are solved.

在此基础上，通过反演得到木结构榫卯连接计算模型的刚度，解决了噪声环境中无法按传统方法进行动力参数识别及类似木结构由于榫卯连接刚度不能准确确定而无法进行合理计算的问题。
