According to the deterioration mechanism of concrete, the model of life perdiction in the corrosion form of corrosive medium and high heat were based on the penetration of chloride with the rustiness of steel and the carbonization of concrete with the rustiness of steel. The calculation results of service life of the origin concrete and new mending materials were close to the actural phenomenons.

根据两种腐蚀形式的劣化机理，建立以氯离子渗透和钢筋锈蚀以及温度影响下的混凝土碳化和钢筋锈蚀为主体的钢筋混凝土使用寿命预测模型，并分别对原有材料和新修补材料进行使用寿命预测，预测结果与实际工程相吻合。

Economy and Safety: a Xenon lamp has a service life of 2500 hours, up to a car's service life, 10 times that of a general halogen lamp, showing worthwhile value.

The results indicated that substrate sandblast contributed to enhance the adhesion between the titanium substrate and the MMO coating, while increasing in the coating mass led to increased durability of the anode, and the coating consumed rate of the coated anode was almost zero.

所研制的RuIrTiSnCo涂层钛阳极具有良好的电化学稳定性和较长的寿命，强化寿命达到96h，约为次氯酸钠发生器标准的5倍，是海水介质外加电流阴极保护中比较理想的辅助阳极。

Take consider of the comparison of the light efficiency and the color rendering index we can find that: one piece of 1000W plasma lamp can equivalence to 2 pieces of 1000W metal halide lamp( no considering the light declining in ceramics metal halide lamp running ), and the lifetime of plasma lamp is 2 times to the metal halide lamp, so as a total by considering the lifetime and light efficiency indexes the one shot cost of metal halide is : 2×6500×2=26000YRMB, So we can find that the plasma lamp can save us 20500YRMB in the one shot cost.

根据两款灯发光效率和显色性的工程照明指标相比较得出：1个1000W的等离子灯相当与2个1000W金卤灯的照明效果（不计陶瓷金卤灯的后期光衰），而等离子灯的寿命是金卤灯的2倍，综合寿命和照明效果两项指标，在一次性投入上，金卤灯是2×6500×2=2.6 万元，由此可见，等离子灯的一次性投入比金卤灯节省2.05 万元。
