随着我国工业化进程的推进,居民日常用电需求不断提高。为了解决城乡用电量的需求,城网改造项目逐年增加,配网自动化的建设在运行管理中发挥着重要的作用,但在配网自动化的建设和运行管理中,同样存在着一些不足。本文旨在针对配网自动化建设与运行管理进行简要分析,希望能为以后的配网工作提供一定的参考。     

Role of CD97stalk and CD55 as molecular markers for prognosis and therapy of gastric carcinoma patients

Objectives: To explore the mechanism of development and aggressiveness in gastric carcinomas by investigating the expression and role of CD97 and its cellular ligand CD55 in gastric carcinomas. Methods: Tumor and corresponding normal mucosal tissue, collected from 39 gastric carcinoma patients, were examined by immunohistochemistry and RT-PCR for the expression of CD97 and CD55. Results: CD97stalk was strongly stained on scattered tumor cells or small tumor cell clusters at the invasion front of gastric carcinomas. The expression of CD97stalk was frequently observed in tumors of stage Ⅰ and T1 gastric carcinoma patients. The expression of CD97stalk between Stage Ⅰ and Stage Ⅱ, Ⅲ, Ⅳ specimens showed significant difference (P＜0.05), between T1 and T2, T3, T4 specimens also showed significant difference (P＜0.05). Specimens with tumor invasion depth limited in mucosa of T 1 specimens showed higher positive CD55 expression than specimens with the same tumor invasion depth in T2, T3, T4 specimens, the expression of CD55 between T1 and T2, T3, T4 specimens was significantly different (P＜0.05).There was strong correlation between the distribution patterns of CD97stalk and CD55 on tumor tissues (r=0.73, P＜0.05). Signet ring cell carcinomas frequently contained strong CD97stalk and CD55-staining. Conclusions: Our results suggest that CD97stalk is probably involved in the growth, invasion and aggressiveness of gastric carcinomas by binding its cellular ligand CD55. CD97stalk and CD55 could be useful as molecular markers for prognosis and therapy of gastric carcinoma patients.

施工期间考虑非机动车干扰的交叉口配时设计

为了提高施工期间交叉口的安全性能,以福州轨道2号线建设中的古田路与新权路交叉口为研究对象,主要考虑非机动车对左转机动车的干扰。通过现场基础数据的采集,针对非机动车干扰数与同一进口道左转车辆车头时距进行回归分析,得出机非冲突函数,获得理想的拟合效果,再运用Synchro提出新的配时方案并对方案进行优化评价。比较优化前后的控制效果,可得:在早高峰阶段,非机动车干扰数与车头时距拟合关系符合二阶多项式形式;交叉口总延误降低8.8%,平均停车次数降低9.8%。

Aggregate gradation design of asphalt mixture with stone-to-stone contact based on fuller＇s model

Based on Fuller＇s model, a gradation design is presented for the load-carrying capacity of an asphalt mixture with stone-to-stone contact. The coarse aggregate gradation, fine aggregate and filler gradation are respectively designed for their different effects on an asphalt mixture with stone-to-stone contact. The equation of coarse aggregate gradation is deduced from the Fuller＇s model. Fine aggregate gradation is calculated by using Fuller＇s equation. The asphalt mixture with the 16 mm maximum size of aggregate is verified. When the coefficient of coarse aggregate gradation is 0.35 and fine aggregate gradation is 0.25, the volume parameters of asphalt mixture meet the technical specifications. Moreover, the high temperature stability and crack resistance at low temperature are all well.
