本文通过对黑生料球在不同煅烧温度下的残余碳、失重率及游离氧化钙等的测定,对立窑黑生料球的燃烧与反应特性进行了研究。认为黑生料球的燃烧大致可分为三个阶段。根据实验中游离钙的变化规律,并结合有关煅烧理论,肯定了黑生料煅烧的优越性。而实验中机械不完全燃烧现象,说明了“高灰分”对料球燃烧反应的影响,为实际生产控制提供了依据。 相似文献

This paper presents two n-channel organic heterojunction
transistors with modified insulator by using
hexadecafluorophthalocyaninatocopper (F16CuPc)/copper
phthalocyanine (CuPc) and F16CuPc/pentacene as the active
layers. Compared with a single-layer device, it reports that an
improved field-effect mobility and a 6-fold higher drain current are
observed. The highest mobility of 0.081~cm2/(V.s) was
obtained from F16CuPc/CuPc heterojunction devices. This result
is attributed to the dual effects of the organic heterojunction and
interface modification. Furthermore, for two heterojunction devices,
the performance of the F16CuPc/CuPc-based transistor is better than
that of F16CuPc/pentacene. This is attributed to the
morphologic match of two organic components. 相似文献
