Then the sustainable development of Qitai artificial oasis was discussed. Researches showed that the oasis development has gone through three phases: The first was harmonic stage before the middle of 20, the oasis developed according to water resources. The second was unharmonic stage from 1950's to 1980's because of unreasonable policies, that is cultivated area enlarged rapidly and water resources exploited backward. As a result, land output was lower, and environment destroyed heavily. The third stage is after 1980's, the new fragile balance between oasis and its environment was established on the base of the more and more ground water utilization.

研究认为奇台人工绿洲人地关系发展经历了三个阶段：第一阶段是20世纪50年代以前，&以水定地&的相对协调发展时期；第二阶段是20世纪50-80年代人地关系发展失衡时期，人工绿洲迅速扩张，水资源开发滞后，耕地因缺水灌溉而成为低产田，环境破坏严重，人地发展失衡的原因是政策因素；第三阶段是20世纪90年代以来人地关系脆弱平衡时期，决定其平衡的因素是不断增加的地下水开采量。

However, they met obstacles during their practices due to the limitation of Chinese ideology, the lag of law construction, the unmatured markets and the incomplete understanding of ESO. Therefore ESO cannot take effective in these enterprises.

但是，由于国内思想意识的局限、法制建设的滞后、各类市场培育的不完善，以及对于股票期权制度本身的认识不全面，这些企业在尝试过程中遇到了很大的障碍，其激励效应并未能够充分体现。

And the superhydrophobic phenomena could be explained by two typical thoeries: Wenzel model and Cassie model.

在表征表面超疏水性时，除常用的θ、α外，接触角滞后Δθ、斜面上液滴滞留在材料表面上的最大半径Rc、两种状态转化时的临界压力Δp以及液滴落下后能反弹的临界撞击速度Vc也是非常重要的参数。

We have shown that for an Al thickness of about 1.2 nm a transition from strongly ferromagnetically coupled Co and Ni80Fe20 characterised with single hysteresis loops to well separated magnetisation loops evident for weakly coupled layers occurs.

我们已显示，一·厚度，大约 1.2 的好分开磁化循环明显，-助学金网，因为弱耦合的层出现循环的纳米强烈 ferromagnetically 耦合的合作和 Ni80Fe20 转换特色的单一滞后。

However, in the old urban area ,because of lackness of afforesting land and other economics and society factors, the green land is built far lagged behind the city development,and can t meet the demands of inhabitant.

但是，在很多城市的旧城区，由于绿化用地紧张以及各种经济社会因素的制约，绿地建设远远滞后于城市的发展速度，不能满足当地居民的需要。

The modeled cell sizes of Huashan pine and its evolution coincide greatly with the observed one. Response of the measured cell size chronologies to climate indicate that the growth of Huashan pine is mainly effected by the precipitation of current growing season from April to July and of the prior year.

所建立的细胞大小年表对气候的响应函数结果，揭示出华山松的生长主要受生长季中4～7月份以及滞后一年降水的影响，而温度只是在生长季节开始的4月份起限制作用。
