尽管传统的命令控制型环境法规并未明文要求政府避免实施会对少数种族和低收入社区造成不当影响的行为,但是那些法规显然也并非鼓励污染的不当分配。相反,诸多以市场机制为基础的环保措施却明显鼓励污染者将污染转移到低收入社区,常常不可避免地加剧环境权益分配不公问题。

1988年世界钼金属与矿物年评

由于受商品行情看好及钢铁市场复苏的影响,1988年钼需求量有了显著地增加。与其它铁合金及其本身的价格历史不同,钼需求量的增加并没有导致钼价上扬,这是因为原钼生产者们迅速改变了已趋好的市场条件。 1988年市场经济国的钼需求量,包... 详细信息

由于受商品行情看好及钢铁市场复苏的影响,1988年钼需求量有了显著地增加。与其它铁合金及其本身的价格历史不同,钼需求量的增加并没有导致钼价上扬,这是因为原钼生产者们迅速改变了已趋好的市场条件。 1988年市场经济国的钼需求量,包括向东欧集团的出口量,估计约为20000万磅,这要比1987年高出2500万磅(见表2)。相比之下,1988年市场经济国的钼产量,包括金属损失和从中国的进口量,只有17500万磅(见表1)。1988年上半年。

Communications in Theoretical Physics 2013年第6期59卷 664-670页

作者： stephen johnson Anjan Biswas stephen johnson and Anjan Biswas Department of mathematical Sciences Delaware State University Department of mathematics Faculty of Science King Abdulaziz University

This paper studies the adiabatic dynamics of the breather soliton of the sine-Gordon equation. The integrals of motion are found and then used in soliton perturbation theory to derive the differential equation governing the soliton velocity. Time-dependent functions arise and their properties are studied. These functions are found to be bounded and periodic and affect the soliton velocity. The soliton velocity is numerically plotted against time for different combinations of initial velocities and perturbation terms.

交流耦合的硅条探测器有较高的电压跨接在耦合电容上面,坏的耦合电容使约50V 电压加到 SVX 器件,测量了坏的耦合电容对 SVXD(rod soft 3 μm)、SVXH(rad soft 1.2 μm)和 SVX2b(tad soft 1.2 μm)放大器/读出器件的影响.试验结果表明,当一个过载电压直接加到一个 SVX 道时,相邻的一些道发生饱和,这种效应是由于在 SVX 基片内的电流扩散而不是探测器的表面电流形成的。文中讨论了饱和量大小和可能的解决途径。
