不实用的

The intention of science innovation is to explore the nature. The purpose to learn for non-practical use and to break away from fatuity is the essence of science innovation. Paying attention to seeking the matter behind the natural phenomena makes the science innovation persistent. Skeptical and critical spirit lead science innovation perpetual.

其中探索自然界是科学创新的初衷；为了求知和摆脱愚蠢而不为任何实用目的是科学创新的本意和目的所在；注重探寻自然现象背后的原因使科学创新的源泉永不枯竭；怀疑和批判精神使科学创新永无止境；而个人自由和人与人平等是科学创新良好氛围的前提。

Some relations between generalized KT-properly efficient solution and generalized H-local-properly efficient solution are obtained under appropriate conditions.

在实用中，由于在给定的约束条件下求得的目标函数的最优值，有时会不符合人们的要求，因此有必要考虑当目标函数的最优值作适当改进时，如何使约束条件进行极小扰动的问题。

And the author also gave us a example, the method is a new method to lower the dimensions of data.

该方法是不同于主成分分析法的一种新的降维方法，它能有效地减小多重共线性问题带来的影响，尤其在处理数据多重相关性突出的武器费用数据时，该方法有着良好的效果，最后，作者用一个实用算例证明了其有效性和可行性。

The mode of life in preliterate society , based upon kinship and functioning in accordance with the principles of cooperation and mutual aid , did indeed justify the adjective commounal ; it was the noun communism that was resented ---if not feared ---because of its Maxist connotation.

文字出现在前社会的生活方式建筑在亲属关系上，生活右依据的基本原则是合作和互相帮助。这种生活方式证实用"群居的"这个形容词来描绘十分恰当。如果说不是惧怕，而在心理上抵制的则是"共产主义"这个名词，原因在于其马克思主义的内涵。

Superior geographical environment, strong technical force, unique production process technology, modern equipment and the advanced and practical stable and reliable product quality, so I became unshaped refractory, light burning stereotypes Products, one of professional manufacturers.

优越的地理环境、雄厚的技术力量、特有的生产工艺技术、现代化的先进实用装备和稳定可靠的产品质量，使我公司成为不定型耐火材料、轻烧定型产品的专业生产厂家之一。

Though the diatomaceous earth belongs to the advantage ores of resources of our country, however, the present development level is still not high, reaching the world level except a few products, the quality of most products also waits to improve, it is obvious , have important theory meaning and practical value to the further research of the diatomaceous earth.

虽然硅藻土属于我国资源的优势矿种，但目前的开发水平还不高，除少数产品达到国际水平外，大多数产品的质量还待提高，可见，对硅藻土的进一步研究具有重要的理论意义和实用价值。

Ribon has database itself that is used to manage all special data, but it is not fit for domestic factories, furthermore, its openness is also limitary, dont surport the openness and interconnection of morden popular database, so studying and developing Tribon is necessary and practical.

RIBON软件本身具有专门管理各个专业数据信息的数据库，但它不适用于国内的造船厂，而且他的开放性也很有限，不支持现代主流数据库的开放互连功能，因而，对TRIBON软件进行研究和开发是很有必要和实用价值的。

Ideally, that should have emerged from a fresh election. But the country lacks both the time and the stomach for this. Mr Duhalde, whom Mr de la Rua defeated in 1999, is no paragon.

理想的方法就是从新的选举中产生，然而这个国家即缺少时间又没有这样的肚量。1999年曾被 Rua 击败的 Duhalde 先生不是个模范人选，但与 Rodrigues 先生不同，他至少是个实用主义者，并且是个重量级的政治人物。

On the base of reviewing the development of NSP models, some deficiencies of existent models are analysed and listed as follows: most models can be applied only to very small watershed; mechanism models involve too many parameters which can not be calibrated properly by limited data; amoung practical models, empirical models are much more common than mechanism models; most models are focus on the conservative soluble pollutants rather than non-conservative and particulate pollutants; almost all models rely highly on the measured data, and there are fewer studies about the load estimation for ungauged areas.

本文在评述非点源污染模型研究进展的基础上，分析了现有模型的不足，主要有：大多数模型只能适应于很小的流域面积；机理类模型参数过多，率定困难，应用效果不理想；实用模型中，经验类模型多，机理类模型少；对保守性的液态污染物研究得较多，对非保守性和固态污染物研究得较少；各类模型均高度依赖于实测资料，无资料地区的模型或预测方法研究得很少。

To have the level of fourth-generation technology, thanks to good fortune by the German-made automatic winding machine AC338 for example, with the third-generation type of comparison, the practical winding speed of nearly 30 percent, most can be as high as 2 000 m / min;筒纱quality increased yarn Uster CV value of the two machines are basically the same though, but the quality of yarn, such as details of 1000 meters from 14.5 to 12, 17.24 percent lower; km thick section from 134.3 to 121.7 , 9.38% lower; Neps kilometers from 121.6 to 115.5, lower 5%; 3 mm in length Hairiness (months / 10m) from 135 down to 102, reduced 24.4%; 14.36% increase in production; production efficiency 8.5%, not筒纱the use of high-quality, the following procedures brought about by economic interests.

以具有第四代技术水平的，由德国赐来福公司制造的AC338型自动络筒机为例，与第三代型机比较，实用卷绕速度提高了近30%，最可高达2 000 m/min；筒纱质量大幅度提高，乌斯特条干CV值两机虽然基本相同，但纱的质量如千米细节由14.5降至12，降低了17.24%；千米粗节由134.3降至121.7，降低了9.38%；千米棉结由121.6降至115.5，降低了5%；3 mm长度毛羽(个/10m)也由135降到102，降低了24.4%；产量提高14.36%；生产效率提高8.5%，这还不算使用高质量的筒纱后，后道工序所带来的经济利益。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
