马赫反应效应在炸药爆轰合成金刚石中的应用

在爆轰法合成超细金刚石中，利用马赫效应提高金刚石得率。用Ｗｈｉｔｈａｍ方法计算了马赫杆上的爆轰参数。实验采用中间为ＴＮＴ的药柱、外边包裹ＴＮＴ／ＲＤＸ（３０／７０）的装药，在爆炸罐氮气介质中爆炸，超细金刚石得率为６％，包裹盐后得率超过１０％。     

THE STIMULATORY EFFECT OF HEAVY METAL CATIONS ON PROLIFERATION OF AORTIC SMOOTH MUSCLE CELLS

Heavy metal cations Cd~(2+), Pb~(2+), and Hg~(2+)were added to substitute for Ca~(2+)in culture media to study their effect on the relationship between CaM and the proliferation of cultured rabbit aortic smooth muscle cells (ASMC). It was found that all the heavy metal cations studied stimulated the proliferation of ASMC in varying degrees, increased the CaM content in cells at late G_1 stage and decreased the activity of cAMP PDE. These results suggest that the adverse effect of heavy metals may be related to the pathogenesis of atherosclerosis and hypertensive disease.
