It breaks down schools ' test scores by at least 36 categories , and if even one group of students ? for instance , hispanic or disabled students ? doesn ' t improve , the entire school misses its " adequate yearly progress " goal 它撤消了至少有36项分类的学校评估制，甚至即使有一组学生，比如西班牙学生或伤残学生状况没有改善的话，整个学校将失去“年度先进”称号。
Even at more moderate levels of warming , all the evidence - from detailed studies of regional and sectoral impacts of changing weather patterns through to economic models of the global effects - shows that climate change will have serious impacts on world output , on human life and on the environment 甚至即使变暖趋势相对缓和，从对气候模式变化给地区及行业带来影响的详细研究到全球影响的经济模式所提供的各种证据，都显示出气候变化将对全球产量、人类生活和环境产生严重的影响。
Most of partial differential equation arising from physical or engineering science can be formulated into conservation form : it directly reflects conservation laws in natural sciences . from viewpoints of fluid dynamics , it can be obtained from the mass , momentum , energy conservation laws . because the form ( 0 . 2 . 1 ) has no other terms such as dispersion , diffusion ( caused by nonuniformity of some physical states ) , reaction , memory , damping and relaxation etc , smoothness of solution of ( 0 . 2 . 1 ) may be loss as times goes on . even for the smooth inital data , solutions of ( 0 . 2 . 1 ) become discontinuous in a finite time 由于双曲守恒律( 0 . 1 . 1 )没有其它项，如色散( dispersion ) ，扩散( diffusion ) (某物理量分布不均匀引起的输运) ，反应( reaction ) ，记忆( memory ) ，阻尼( damping )及松弛( relaxation ) (描述非平衡态)等，而仅有输运或对流项( convection ) (由于流体的流动引起的输运)时，守恒律( 0 . 1 . 1 )的解失去光滑性(这里不特殊说明守恒律就指该意义下) ，甚至即使光滑的初始数据，解随着时间的发展会变成不连续，这在物理上表现为激波的形成。
