改变地

Songs were often resorted to in dairies hereabout as an enticement to the cows when they showed signs of withholding their usual yield; and the band of milkers at this request burst into melody - in purely business-like tones, it is true, and with no great spontaneity; the result, according to their own belief, being a decided improvement during the songs continuance.

当奶牛一出现出奶量比平常减少的迹象，人们往往就采取在牛奶场唱歌的办法，想用这种办法把牛奶引出来；老板要求唱歌，这群挤牛奶的工人们就放开喉咙唱起来--唱的完全是一种应付公事的调子，老实说，一点也没有自愿的意思；结果，就像他们相信的那样，在他们不停地唱歌的时候，出奶的状况的确有了改变。

Would you have done it differently on hindsight, if so how would you have changed your approach?

您是否不同地会做它在事后的认识，如果如此您怎么会改变您的方法？

The homogeneous calibrator and ideal material calibrator are considered respectively. From the optimal results" analysis and comparison, we can see that the ideal material calibrator improves greatly the cooling uniformity of plastic profile by changing the cooling channel"s location, size, number and adjusting calibrators material distribution.

分别考虑均质定型模和理想材料定型模，从优化结果分析、比较可以看出，理想材料定型模通过改变冷却水道的位置、尺寸和数量以及调整其材料分布规律，极大地改善了塑料型材的冷却均匀性和冷却效率。

Linearly varying horizontal and vertical deflection voltages are generated that are proportional to the required changes in the x and y directions to produce the smooth line.

这是根据x方向和y方向需要修改的实际量，线性地改变水平和垂直偏转电压而实现的。

The result indicates that the damping term drastically changes the asymptotic behavior of the hyperbolic equation.

分析结果表明，阻尼项强烈地改变双曲型方程解的渐近行为，强阻尼双曲型方程组的能量E随时间按指数衰减，即E≤Cexp。

The deformation mechanism is mainly the single-slip and cross-ship, the fracture mechanism is mainly the congregation of transgranular micro-hole, and large uniform deformation occurred before tough fracture, and therefore, the ability of plastic deformation and the mechanical properties of the material were remarkably improved. These fully indicate that the new melt-treatment developed in this work is an effective and advanced technique, and further testify that the improvement of metallurgical quality of the material is the key to enhance its mechanical properties, especially its plastic deformation performance. The results of tensile and compression tests at elevated temperature also indicate that the suitable hot-working temperature range is 400～450℃. 4. A steady-state plastic flow exists during the plastic deformation of the aluminum sheet used for pressure can at elevated temperature. A hyperbolic sine relationship can be satisfied between the steady-state flow stress and strain rate by introducing an Arrhenius term which involves some thermal activation parameters, i.

压力罐用铝材中的主要冶金缺陷为Al〓O〓夹杂物、气孔及富Fe杂质相；高效熔体处理显著改善了材料的冶金缺陷的存在形态，使含杂量明显减少、夹杂物尺寸变细小且分布均匀，富Fe杂质相变为细小、分布均匀的团球状或短棒状的复杂化合物，同时也明显细化了结晶组织；此外，由于高效熔体处理有效地减少了材料中裂纹萌生源数量，因而改变了材料的塑性变形微观过程及断裂方式，主要以单滑移和交滑移进行塑性变形，断裂方式为穿晶微孔聚集型，韧性断裂前产生了大量的均匀变形，不易出现变形失稳，从而显著提高了罐用铝材的塑变能力和力学性能。

How can you determine that the change can cause the idioplasm resources to be destructed, but not to be developed well?

你又怎能确定改变基因会使种质资源遭到破坏，而不是更好地发展？

Thirteen years later, despite the Labour government pumping money into schools and constantly changing the way they are run, British children remain ill-educated compared with their counterparts elsewhere, the poorest in particular.

尽管之后工党不断地向教育领域投入资金并且积极改变教育模式，但是13年后的今天，英国的孩子们比起其他国家的孩子们所受的教育仍然是落后的，甚至是最糟糕的。
