For the ill conditioned load flow caused by the error produced in the transformation from electricity quantities to average power, direct current load flow and sensitivity vector are presented to find out the ill node, then by adjusting the load curve and generation curve in a certain principle, which is shown in detail with several flow charts, a new operation mode is reestablished to ensure the convergence of the calculation. Optimal multiplier method is proposed to work out the least square solution according to ill conditioned structural power network. The electricity quantities flow method enhances the reliability and accuracy of the calculation of the power transmission losses.

The findings knew that the ships collision is a type of an act of tort , its liability asks to recompense is looks carefully the state of fault to decide , generally may divide into the force majeure or the unknown cause collision , the mutual fault of both sides collision and so on , because if the force majeure or the unknown cause collision , undertake voluntarily by the victim , if an error of the side undertakes the damage compensate responsibility by the inflicter , when if both sides have mutually to cause its faults , basically it depends on the fault to share , but if it's unable to judge the proportion then the average to share is necessary.

研究结果得知，船舶碰撞为一典型之侵权行为，其责任求偿乃端视过失型态而定，一般可分为不可抗力或不明原因之碰撞、单方过失碰撞及双方互有过失碰撞等，而若因不可抗力或不明原因之碰撞者，由受害人自行承担，若纯为一方之过失者则由加害者承担损害赔偿责任，若因双方互有过失所造成时，原则上依过失程度分担，但若无法判定比例时则平均分担。
