迁移问题

According to the point "some assumptions about steady state diffusion are valid when non steady state diffusion is studied"and carbon conservation law,the carbon contents' leaping condition is given.

按照"在研究非稳态扩散问题时，稳态扩散研究中的有些假定仍然是有效的"的观点，利用碳的守恒定律给出碳浓度的跳跃条件，结合扩散通量条件，推导结果发现这种内边界条件无法解决F／A界面上的迁移。

Now more than ever, issues such as climate change, obesity, stem cell research, green technology, and evolution are migrating from scientific journals to the nonscience community, from school halls to the halls of Congress.

现在有比以往更多的问题，如气候变化，肥胖，干细胞研究，环保技术演化的迁移从科技期刊到非科学社会，从学校礼堂到国会大厅。

Yields improved as there were no major weather concerns and experienced southern producers migrating to the states of the Center-West and northeasterly to Maranhao and northward to parts of Para, for example, explain much of the production boom.

由于天气状况没有什么大问题，收获率有所提高。另外，产量的增长还有其它方面的原因，比如，南方一些有经验的生产者向中西部各州、向东北部马伦豪州以及向北部帕拉州部分地区的迁移。

The nuclide migration model is a coupled parabolic equations with initial and boundary conditions.

该核素迁移模型是一个耦合的抛物型方程组定解问题。

The big question is whether they will be able to find sufficient prey in areas where they are looking.

最重要的问题在于它们能否在新的迁移地觅得充足的食物。

Therefore, the research on the radionuclide migration behavior is an extremely essential question for the high-level radioactive waste disposal.

因此对放射性核素的迁移行为和规律的研究是高放废物处置的一个十分关键的问题。

What do these home movers actually aim is to make your relocation free of worries and problems.

什么这些家庭推动者实际上目的是使您的迁移自由的忧虑和问题。

However, mobility degradation and threshold voltage instability are the mainly concern.

然而，在高介电常数的介电质中所产生的迁移率衰减与临界电压的不稳定都是其主要的存在问题。

However, mobility degradation and threshold voltage instability are the biggest concern.

然而，在高介电常数中所产生的迁移率衰减与临界电压漂移都是主要的存在问题。

Since historical times,England ,where the early inhabitants were Celts, has been conquered three times .
