No country in history has emerged as a major industrial power without creating a legacy of environmental damage that can take decades and big dollops of public wealth to undo.

在历史上，任何一个工业大国的出现都伴随着一段环境破害的故事，附上上数十年的努力和巨大的民财。

"I have examined a file of each of the newspapers published in Chelmsford and Colchester," continued Robert, without replying to my lady's last observation, and I find in one of the Colchester papers, dated July the 2nd, 1857, a brief paragraph among numerous miscellaneous scraps of information copied from other newspapers, to the effect that a Mr. George Talboys, an English gentleman, had arrived at Sydney from the gold-fields, carrying with him nuggets and gold-dust to the amount of twenty thousand pounds, and that he had realised his property and sailed for Liverpool in the fast-sailing clipper Arqus.

&我曾查阅了分别在切尔姆斯福特和科尔切斯特出版的报纸的两份合订本，&罗伯特没理睬爵士夫人的最后那句话，迳自继续说下去，我在一八五七年七月二日出版的科尔切斯特报纸上看到：在许多从别的报上抄来的各式各样的短讯之中，有那么短短的一段新闻，大意说：有一位乔治·托尔博伊斯先生，一位英国绅士，从金矿地带到达悉尼，身边带着金块和金砂，价值达两万英镑，他已将金块等兑换成现款，乘坐快速班船'百眼巨神号'前往利物浦。

Edit this paragraph the reasons for the color reaction of flame When the alkali metal and its salts in the ignition flame, the atoms absorb the energy of the electron from the orbit of low-energy transition to a higher energy orbit, but at a higher energy orbit is unstable electronic, it is fast transition back to a lower energy orbit, then the energy will be redundant form to emit light.

编辑本段焰色反应的原因当碱金属及其盐在火焰上灼烧时，原子中的电子吸收了能量，从能量较低的轨道跃迁到能量较高的轨道，但处于能量较高轨道上的电子是不稳定的，很快跃迁回能量较低的轨道，这时就将多余的能量以光的形式放出。

In career choices, staff and freelances for 8%; In monthly income, only 2% of the crowd of more than 5000, 5000 accounted for less than 8%-- for low-income groups in the absolute superiority, the second part of your main contact point : choose love than to choose the house, and this shows that the kind of "moral degeneration is getting worse day by day, saying" that is not correct, or that some time ago the symbol of a city,"Ms. 9% choose to marry house," the conclusions of questionable information.

在职业选择上，公司职员和自由职业者占到了8成多；而在月收入上，5000以上的人群只占2成，5000以下的占了8成――低收入人群参与占到绝对优势，联系第二部分大家的主体观点：选择爱情的大于选择房子的，这说明那种&世风日下，人心不古&的断言不正确，或者说前一段时间那条某城市&9成女士选择嫁给房子&的新闻所得出的结论值得商榷。

So recommend the measuring methods of roller friction coefficient.

在制动实验台滚筒的附着系数测量存在的问题上，只是对解决方案进行文字上的描述，论述了如何使用制动实验台滚筒的附着系数测试仪，不支持论文最后一段结论。

Generally, a force representing the load on a turn, or coil, of cable at the bottom of a full cable tank is applied to a short cable samp...

最佳答案：一般来说，一个代表在满的电缆槽罐底部一圈电缆上的负荷的力被施加到一短段电缆样品上。

The sand body thickness and sand grain of gas-producing horizon are lies on incumbent relation of different microfacies. The production has direct affiliation with porosity, permeability, porosity texture.

产气层段砂体在纵向上的厚度与砂岩粒度受控于不同微相在纵向上的叠置关系，产能的高低与储层的孔、渗条件和孔隙结构特征有更直接的联系。

This technique is to make a device to instead those transmitters and reduce the need in pressure gauges. Using the electronic valve and flexible tube to construct the control panel is effective to connect the single pressure gauge with every sensor point in ventilation duct.

利用软管将欲量测之管段的压力导引到控制箱内，并将所有导引来的静压分别安装在一组并联的各电磁阀上，再将所有的动压分别安装在另一组并联的各电磁阀上，而该两组并联电磁阀的底部各安装一根连通管连结至单一差压计的高低压两端，并利用控制组件切换各电磁阀的启闭以达到多点压力监测切换的目的。

The results show that BS 460MPa grade reinforced bar can be produced all from Q235 or 20MnSi billet by the remained heat treatment process but the production cost of the former is lower. When the water pressure minishes, the intensities of reinforced bar reduce; the higher the temperature at the entrance of cooling bed is, the lower the intensities are. Therefore, the commendatory process parameters are that five stages coolers should be opened, water pressure should be all 1.8～2.0MPa and the temperature at the entrance of cooling bed of Q235 reinforced bar should lower than 650℃. The typical microstructure(Q235): the surface layer is tempered sorbite; the transition layer is pearlite and ferrite, and the partial ferrite is acicular; the core is pearlite and ferrite and the grain fineness is 8～10 grade. The yield strength is reduced by 10～20MPa after natural ageing and it can be simulated by artificial ageing(100℃×2h or 200℃×1h).

结果表明，Q235和20MnSi钢都可以利用余热处理工艺生产出性能合格的钢筋，但前者的生产成本较低；水压减小，钢筋强度降低，上冷床温度越高，强度越低，推荐5段水冷器全开，水压均为1.8～2.0MPa，Q235钢筋的上冷床温度应控制在650℃以下；钢筋典型的金相组织（Q235）表层为回火索氏体，过渡层为珠光体+铁素体且部分铁素体呈针状，心部为珠光体+铁素体，晶粒度8～10级；自然时效后屈服强度下降10～20MPa，用人工时效可以模拟自然时效，工艺是100℃×2h或200℃×1h。

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。
