( 2 ) calculation of the combustion parameters the combustion parameters of hmx , rdx , hns - i and b / kno _ ( 3 ) were calculated with vlwr code . the thermodynamic function of boron oxide was fitted by method of the least square to janaf thermo - chemical table , and their coefficients were determined ( 2 )炸藥及點火藥燃燒性能參數計算應用熱力學程序vlwr計算hmx 、 rdx 、 hns -及點火藥b kno _ 3的燃燒性能參數及燃燒平衡產物組成,得到了與密閉爆發器實驗相近的燃燒性能參數。

Bismuth ruthenate and silver were selected as conductor phases and the mixture of calcium oxide - alumina - silicon dioxide ( cao - al _ 2o _ 3 - sio _ 2 ) glass and lead oxide - boron oxide - silicon dioxide ( pbo - b _ 2o _ 3 - sio _ 2 ) glass was selected as inorganic binder phases . it was found that , with the increasing of volume fraction of silver and conductor phase , sheet resistivities descend and there are critical thresholds 實驗發現,隨著功能相百分含量的增加,電阻膜層的方阻值逐漸減小,存在兩個臨界閾值,電阻溫度系數偏向正值;功能相中銀百分含量增加,膜層的方阻值逐漸減小,有一個臨界閾值,電阻溫度系數偏向正值。
