The corrosion inhibitor is one of the most important technologies to enhance the durability of steel-reinforced concrete. A kind of time-saving method was developed to assess the inhibitor efficiency by using a 32 V electric field to accelerate chloride ion migration in concrete. Potentiodynamic polarization scanning test was used to evaluate the corrosion states. The comprehensive efficiency of an inhibitor should be assessed in two aspects： resistance to chloride ion permeability and inhibiting efficiency. The specimens with different mixing amount of sodium nitrite and migration corrosion inhibitors were used to verify the accuracy and reliability of this method. The results show the differences in inhibiting efficiency of the inhibitors clearly, indicating the reliability of this time-saving method.

基于桥梁全寿命周期成本分析理论,系统归纳了长寿命耐候钢桥各阶段成本组成特点,明确了长寿命耐候钢桥全寿命周期经济性评估内容与特征参数,给出了长寿命耐候钢桥成本计算基本假设;从免涂装耐候钢桥与涂装钢桥成本差异出发,对比分析了2种钢桥建设阶段、运营阶段成本计算方法,建立了长寿命耐候钢桥全寿命周期经济性评估模型;以中国3座长寿命免涂装耐候钢组合梁桥为例,计算了长寿命耐候钢桥全寿命周期各阶段成本,明确了涂装、维护方案对长寿命耐候钢桥全寿命周期成本经济性的参数化影响,分析了长寿命免涂装耐候钢桥全寿命周期成本经济性优势。研究结果表明:免涂装耐候钢桥与涂装钢桥成本差异主要体现在钢材与焊接材料价格、锈层检测成本、涂装维护成本与由此产生的环境及用户成本;与4种涂装钢桥相比,免涂装耐候钢桥全寿命周期成本减少11%~21%,在全寿命周期具有显著的经济性优势;水洗周期对成本具有显著影响,水洗周期从每6年1次增加到每年1次时,增加成本占全寿命周期成本差比的5%~11%;当免涂装耐候钢桥涂装面积达70%左右时,其全寿命周期成本大于涂装钢桥。长寿命耐候钢桥全寿命周期经济性评估模型可为桥梁方案设计与技术经济性比选提供依据,从而促进长寿命耐候钢桥的推广应用。

The cooling storage ring (CSR) external-target experiment (CEE) is a spectrometer used in construction to study the properties of nuclear matter in high-baryon density regions at the Heavy-Ion Research Facility in Lanzhou (HIRFL). This study presents the design, simulation, manufacturing, and testing of a half-size prototype of a multi-wire drift chamber (MWDC) for the CEE. First, the performance of the MWDC connected to homemade electronics was simulated. The results demonstrated that an energy resolution of 18.5% % for 5.9-keV X-rays and a position resolution of 194 mu m for protons can be achieved by the current design. Because the size of the largest MWDC reached 176 cm x 314 cm, a set of 98 cm x 98 cm prototypes was built using the new techniques. The positioning accuracy of the anode wires in this prototype is better than 20 mu m. After optimization, using commercially available electronics, the prototype can achieved an energy resolution of 19.7% % for a Fe-55 X-ray source. The CEE-MWDC detector and electronics were simultaneously tested. An energy resolution of 22% % was achieved for the Fe-55 source; the track residuals were approximately 330 mu m for the cosmic rays. The results demonstrate that the current design and techniques meet the requirements of the CEE-MWDC array.
