The paper reports investigation which have confirmed the relation between burningtemperature and formation of minerals,which exists in iron-rch fluornluminate cementIn order to burn iron-rich fluoraluminate cement at lower temperature,the SO_3 contentmust be controlled.     

水平井注蒸汽传热和传质分析

利用质量守恒、动量守恒和能量守恒的原理.推导了水平井注蒸汽过程中.水平井段内汽液两相变质量流的数学模型,并用数值解的方法计算了水平段内蒸汽质量传递和热量传递的规律.结果表明,在注汽参数一定的情况下.水平井段各处吸入蒸汽数量和热量并不相等.蒸汽压力沿井筒变化不大.但干度变化较大.一定完井条件和油藏条件下.随注汽参数的改变。会有三种情形发生:(1)蒸汽只能达到水平井的上半部而不能到达井底;(2)蒸汽刚好到达水平井的井底;(3)蒸汽到达井底后仍有剩余.为了充分利用水蒸汽.因此.必须保证蒸汽注入参数、井结构和油层的互相协调.提出了通过布孔来实现水平井均匀吸汽的建议.并提出了布孔设计方法.

Role of FGF-2／FGFR signaling pathway in cancer and its signification in breast cancer

Fibroblast growth factor-2 (FGF-2) is a member of a large family of proteins that bind heparin and heparan sulfate and modulate the function of a wide range of cell types. It has been proved that FGF-2 stimulates the growth and development of new blood vessels (angiogenesis) that contribute to the pathogenesis of several diseases (i.e. cancer, atherosclerosis). However, many of the biological activities of FGF-2 have been found to depend on its receptor抯 intrinsic tyrosine kinase activity and second messengers such as the mitogen activated protein kinases. This review will focus on the mechanism of FGF-2/FGFR induced signaling pathway in tumor and human breast cancer.     

NMR study on self-assembled cage complex of hexamethylenetetramine and cucurbit[n]urils

Self-assembled complexes between cage com-pounds cucurbit[n = 5—8]urils and hexamethylenetetramine were studied by using NMR techniques. Experimental results reveal that hexamethylenetetramine can lid cucurbit[5]uril to forming self-assembled capsules in which nothing is encap-sulated yet; the cavity of the cucurbit[7]uril can accommo-date a hexamethylenetetramine molecule to form a self- assembled host-guest inclusion. Moreover, both the cavity interaction of the cucurbit[7]uril with hexamethylenetetra-mine稨Cl and the portal interaction of the dipole carbonyl of the cucurbit[7]uril with hexamethylenetetramine稨Cl lead to form self-assembled capsules in which the hexamethylene-tetramine稨Cl are encapsulated in the hexamethylenetetra-mine稨Cl lidded cucurbit[7]uril. Although the structures of the portal and cavity to cucurbit[5]uril are similar, there is no obvious interaction between decamethylcucurbit[5]uril and hexamethylenetetramine, and also between cucurbit [6]uril or cucurbit[8]uril and hexamethylenetetramine.     

固溶处理对7A55铝合金断裂韧性的影响

采用金相组织观察、拉伸实验、Kahn撕裂试验、扫描电镜、透射电镜等方法研究固溶处理对7A55铝合金断裂韧性的影响。研究结果表明:固溶温度对7A55铝合金断裂韧性影响显著,7A55铝合金在450～490℃时固溶,随着温度上升,可溶性粒子减少,断裂韧性增加,到480℃时断裂韧性达到最大值;当温度超过480℃时,由于晶粒的长大,断裂韧性又开始下降;7A55铝合金有很大的淬火敏感性,当以慢速淬火时,晶界非共格析出物尺寸粗大,对断裂韧性不利。
