不变化地

The equation oriented dynamic modeling introduces the time variable into the model system, i.e., the characteristics are variating with time. The modeling of a dynamic process is a combination of process simulation, control theory, chemical unit models and thermodynamics.

而在工业过程中，存在许多不稳定的变化过程，只有通过动态模拟才能更好地掌握这些过程的本质，因此对流程进行动态模拟研究意义重大。

Unnamed grassroots officials quoted by Liaowang said that recent internet uproars reflected changes in the "social mood" amid the global financial crisis. One sign of this, they said, was the greater tendency of internet users to take action rather than simply vent their anger online.

瞭望引用一位没有透露姓名的基层官员的话说，最近网络上的喧嚣，反映了全球金融危机下社会情绪的变化，迹象之一就是，网民们采取行动，而不是简单地在网上宣泄他们的愤怒。

Changeless and hopeless, the tumbrils roll along.

不会变化，也没有希望，死囚车隆隆地前进。

The results show that the RIEMS can simulate the pattem and seasonal cycle of standard deviation of surface temperature and precipitation. Meanwhile,RIEMS is unable to simulate inter-annual variability of precipitation in April and July, although it does pretty well for January and October precipitation.

结果表明，模式能够较好地模拟出温度和降水的标准差的空间分布和不同区域平均标准差的年变化，同时，对降水的年际变率检验发现，模式能够模拟出一月和十月降水的年际变率，而不能模拟出四月和七月降水的年际变率。

The third impetus to rejig the way the world organises itself is a dawning realisation on the part of governments, rich and poor, that the biggest challenges shaping their future—climate change, the flaws and the forces of globalisation, the scramble for resources, state failure, mass terrorism, the spread of weapons of mass destruction—often need global, not just national or regional, solutions.

第三个改进这个世界自我组织方式的推动因素是各国政府，无论贫富，都日渐清醒地意识到，影响他们未来发展的最大挑战，包括气候变化，全球化的利与弊，对资源的争夺，失效状态，恐怖主义愈演愈烈和武器扩散及其造成的巨大破坏，都需要全球性的而不是一国的或区域性的解决方案。

This hypothesises that climate change associated with ice ages regularly shrinks and fragments the forest into isolated "refugia", which go their own merry evolutionary way.

。这个解释是假设，和冰河时代有关的气候变化规律性地减少森林规模，并且把它们分隔成孤立的&生物避难所&，这些避难所然后以自己的方式进行进化，不受外界影响。

The distinction is, however, less clear cut than this suggests, since pidgins and Creoles characteristically operate on a 'post Creole continuum', which itself may be seen as a linguistic expression_r_r of the flux of HYBRID CONTACTS.

然而，自从洋泾滨语与混合语显著地作用于一种&后混合语的连续体&——其本身可被视为杂交接触之变化的语言表达——以来，区别已不是太明确。

Focusing on all these functional traits, 13 functional groups were identified by TWINSPAN (two-way indicator species analysis), and their change with different environmental factors, disturbance types and recovery time was ordinated by DCCA(detrended canonical correspondence analysis).

本文以海南岛霸王岭林区作为海南岛热带林的典型区域，以反映不同环境因子、干扰类型和恢复时间的热带山地雨林为研究对象，在大面积(15hm~2)样地调查的基础上，依据物种的7个功能特性(喜光性、潜在高度、板根大小、木材密度、种子生物量、传播方式和落叶／常绿性)，分别把物种划分为不同类别的功能群，应用NMS分析了各功能群随不同干扰类型和恢复时间热带山地雨林群落的变化规律。

The experimental results show that the size of large particles on coatings surface was decreased obviously by N ion beam assisting bombardment, and surface morphology was optimized. Unitary TiN phase was obtained and softer Ti2N phases were eliminated by N ion beam assisted bombard. As the energy of bombard increased, TiN (111) crystal orientation gradually reduced and (200) gradually enhanced. The micro hardness of coatings reinforced too.

结果表明：N离子束辅助轰击，能够有效地减少和降低膜层表面&大颗粒&的数量和尺寸，消除了膜层中较软Ti2N相，得到了单一的TiN相，随着轰击能量的增加，TiN相结构不发生变化，TiN（111）取向逐渐减弱，而（200）取向逐渐增强。N离子束辅助轰击能量的增加，提高了膜层的显微硬度。

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。
