Considering the fracture temperature field, we calculated physical dimension of the fracture using PKN model, estimated the distribution of full-suspended fracturing fluid in the fracture and the conductivity of sand-packed fracture.

在考虑裂缝温度场对裂缝几何尺寸影响的基础上，使用PKN模型计算了裂缝的几何尺寸，计算了全悬浮携砂液在缝中的运移分布及填砂裂缝的导流能力。

A new analytical model for pressure decline under the condition of forced fracture closure was developed on the basis of material balance theory and the former corresponding fracture models, such as PKN and KGD models.

以物质平衡原理和相关分析模型为基础，对PKN和KGD两种裂缝模型建立了裂缝强制闭合条件下的压力降落解释模型。

After PKN treatment, two varieties of plant height, ear height, ground dry weight, root to shoot ratio decreased.

聚糠萘合剂处理后，两品种株高和穗位高下降，地上与地下部干物重增加，根冠比增加。

With the changes in the international situation, Japan promulgated the Law of PKO and openly sent armed forces abroad under the name of international contribution, which is even more prohibited by the Constitution.

随着国际形势的变化，日本在国际贡献的名目下，制定出PKO法，并公然向海外派兵，这更是宪法所不容许的。

Peace-keeping Operations ( PKO) is an important international systematic arrangement of United Nations, so the relation between China and it is also affected by the national interests' change deeply.

维持和平行动是联合国主持的一项重要的国际制度化安排，中国与这项安排的关系也深受国家利益变化的影响。

It is clear that the best prospect for future growth in lauric oil supply is for an increase in PKO production, as a result of higher palm oil output.

很明显，将来月桂油供应主要取决于棕榈仁油生产的增加，这是棕榈油产量提高的结果。

It is estimated that in near future PKO will substitute coconut oil as the most important resource for lauric oil.

不久的将来，棕榈仁油将取代椰子油的地位，成为最主要的月桂油资源。

But the new PKO is different from the traditional PKO.

但是新世纪的联合国维持和平行动表现出了与传统维和行动不同的新特点。

PKO is a multilateral arrangement that is attended by many nations, and it is carried out in the world-wide, so it provides an opportunity for strengthening communication with other countries.

其主持的维和行动是由诸多国家参加的多边安排，并且在世界各地开展活动，为加强世界各国的沟通和交往提供了机会。

Because of this, China completely takes part in the PKO in the initial stage of the 21st century.

在此推动下，新世纪初期中国全面参加到维和行动机制中。
