Abstract : there are only two set values ( 30 , 45 ) for interior angle of the stimulated directional power relay as the protection in phase to phase short circuit fault . an accurate setting formula for interior angle of the microprocessor - based directional power relay as the protection in phase to phase short - circuit fault is proposed and analyzed , users can set as a calculation value or at least an optimum in the formula . therefore the operation sensitivity and reliability of the directional relay would be improved greatly . the opinion is new and practical 文摘:保護相間短路的模擬式功率方向繼電器內角的整定值只有兩個( 30 、 45 ) ,用戶只能在這兩個值中選其一;分析并提出了保護相間短路的微機型功率方向繼電器內角的準確整定計算公式,用戶可以整定為該公式的計算值或至少為最合理的值,從而能顯著提高方向繼電器的動作靈敏度及可靠性,具有新見解及應用價值。

The slope stability question is influenced by many kinds of inherent factors , for instance geological structure , intensity of rock body , development state of joint and crack , cohesive force ( c ) of the rock , interior angle of friction ( f ) , groundwater , etc . , these objective factors reflect generally their sizes with some quantitative parameter indexes in the past 邊坡穩定問題受多種內在因素影響,如地質構造、巖體強度、節理裂隙發育狀況、巖石的內聚力( c ) 、內摩擦角( ) 、地下水等,這些客觀因素過去一般用某些定量參數指標來反映其大小。

If a straight line falling on two straight lines makes the interior angles on the same side less than two right angles , the two straight lines , if produced indefinitely , meet on that side on which are the angles less than the two right angles 如果一條線段與兩條直線相交,在某一側的內角和小于兩直角,那么這兩條直線在不斷延伸后,會在內角和小于兩直角的一側相交。

For geodesic triangle in 2 - dimensional constant curvature space , the author improves some geometric inequalities on its interior angle by theory of majorization 摘要對于二維常高斯曲率空間上的測地三角形,研究了其內角的優超關系,并運用優超理論得到了若干新的關于其三內角的幾何不等式。

Ask students to demonstrate a proof of the theorem stating that the sum of the interior angles of a triangle is equal to 180 ? 讓學生演示歐幾里得41號命題的證明:如果一個平行四邊形與一個三角形有相等的底邊長,又同時夾于兩平行線之間,那么這個平行四邊形是這個三角形的兩倍。

When other conditions are the same , to the interior angle of friction , mean value of glue and gather play a bigger role to stability and dependability of slope 均值大小對土坡穩定性和可靠性起著更大的作用。在南方,降雨是公路邊坡穩定性的主要影響因素之一。

Up to a certain sum of the interior angles on one side of the transversal the two lines might indeed meet . 截線一側兩內角到達一定的和數,兩直線可能一定相交。
