In order to maintain the system stability the constraint is such that the phase-angle difference between any two generating sources in the to-be-interconnected electrical power systems should not exceed a permissible value, The tie line is selected based on the minimum annual cost, with the costs of both the new tie line and the necessary network expansion in the original electrical power systems...

该模型以联合电力系统中各电源点之间相角差均不超过允许值作为保持系统静态稳定性的约束条件，在按年费用最小选择联络线方案时，同时计及了新建的联络线和原有电力系统中网络的扩建。文中还给出了某两个电力系统联网的分析计算结果。

A given tectonic force may be resolved into two parts: homogeneous stress and differential stress. Homogeneous stress refers to isotopic pressure,which is superimposed on the original pressure and affects the equilibrium of various chemical reactions. It is also a factor that influences petrogenesis,metallogenesis and metamorphism.

构造力可以分解为两部分一部分是均应力，指各向相等的应力，它叠加在原有压力之上，并且影响着各种化学反应的平衡，也是成岩、成矿和变质作用的影响因素。

The laser would operate using the existing Phalanx radar and command and control system.

激光系统将使用原有的密集阵系统的雷达和指挥与控制系统。

实验结果显示：支架中的成纤维细胞、脂肪细胞及组织纤维间质完全去除，胶原纤维得到了松散，并维持其原有的天然三维网络多孔结构；该材料透水汽性处于3000g.m-2.d-1左右，适合创面恢复；体外降解时间处于25～50h之间，并可根据需要调整工艺条件控制降解时间；拉伸强度介于10.20～11.50MPa之间，具有良好的拉伸强度；收缩温度介于70～85℃之间。上述结果表明该材料已解决了猪脱细胞真皮基质渗透性差、降解速度过慢的缺点，并且其透气性和拉伸强度高、降解性优良且可控，符合组织工程支架材料的要求。

Set on the piano nobile of the Niccolini Palace, Residenza del Moro has been meticulously restored and renovated in keeping with the original beauty and splendour of this 16th Century palazzo. There are eleven elegantly refined and individually designed suites that are artistic havens adorned with priceless frescoes, antiques, brocades and silks, and a remarkable collection of modern art.

The improvements consist of two parts: 1 generalizing the PDE based approach to contrast enhancement to adapt to any specified stretch function for global and local contrast enhancement; 2 proposing a piecewise linear stretch function design method to achieve better histogram equalization.

改进包含两个方面：1 修改并推广了原有的基于PDE的灰度增强方法，使之可适用于任何设定的灰度拉伸函数；2给出了一种通用的分段线性拉伸函数设计方法，它较采用累积直方图作为灰度变换函数可达到更好的直方图均衡化效果。
