質子能量刻度採用1檔,每道能量h約在0 . 0167mev道,但是在e _ 1探測器中的能量刻度隨著能量的增加略有所下降,這是由於高能質子伴隨有較多的核反應道對粒子探測產生了干擾,從而增加了在e _ 1探測器中的能量沉積道數,使得每道能量略有所下降,另一個因素可能是探測器厚度的不均勻性的影響,但這並不影響對粒子的鑒別。Having investigated composites of ep coating ultramicro iron using atpu as surface agent, results showed that with increasing amount of atpu, density, complex permittivity ( ) and complex permeability ( ) of composites decreased, and retentivity and coercivity increased

對于冷加工后經再結晶退火處理的zr - 4合金,軋制方向的低周疲勞壽命比橫向要大。隨著_ p的降低,兩個方向的低周疲勞壽命的差別相應增加,這是由於合金中存在織構的緣故。冷加工后經再結晶退火處理的zr - 4合金在固溶處理后,抗疲勞性能明顯降低,這主要是由於固溶處理降低了合金的schmid因子;固溶處理后在相區的退火對疲勞性能有影響,即500 1 . 5h退火的抗疲勞性能要優於750 1 . 5h退火,這主要與500 1 . 5h退火的合金中沉澱相粒子的數量較少有關。It is firstly found that for alloys in metastable region, with enhancement of atomic interaction energy, volume fraction and density of " phase particulate are increased, size and nucle ' ation rate of ordered phase raised, decline pace of composition in disordered matrix around the order phase is accelerated, composition order parameter and long range order parameter of ordered phase increased, i. e. process of clustering and ordering are accelerated
