This study was conducted to quantitatively evaluation the deterioration of concretes and effect of chloride on damage.In this paper,2 sets of plain concretes with W/B being 0.35 and 0.45 respectively,and 2 series of concretes with 20% and 30% replace ratio of fly ash,were made.Two kinds of corrosion system were used;one was concrete stored in corrosion solution for 500 d,another was drying-immersion cycles.

研究了水胶比为0.35和0.45的普通混凝土和粉煤灰掺量为20%和30%的粉煤灰混凝土在2种溶液(5%Na2SO4溶液，3.5%NaCl+5%Na2SO4复合溶液)和2种腐蚀制度下各混凝土的损伤失效规律、特点及氯盐对混凝土硫酸盐损伤的正负效应。

Thus, one can think of it as counting machine cycles.

所以可以视为计数机器周期。

But the number of deaths in the two groups whose day-and-night cycles had been tampered with was far higher.

Acknowledge that the following practical cycles can be heat engine cycle of ideal gas, such as the internal combustion engine , Diesel cycle , Brayton cycle.

了解并掌握内燃机和燃气轮机装置的实际工作循环可抽象为理想气体的热机循环。

Acknowledge and grasp the installations and processes of Otto cycle , Diesel cycle , Brayton cycle , Combined cycles in stationary gas turbines for power production

掌握各循环装置及工作流程，并能分析该循环的热力过程。

The CV curves in 10 cycles are nearly all the same without any change. The initial discharge capacity of the product is 117mAh/g and its discharge potential plateau is 3.2~3.3V, which could be comparable to that made by the decomposition of ferrous oxalate under the same conditions.

循环伏安测试发现样品在10周内基本上无变化，产品的首次放电容量为117mAh/g，放电电压平台为3.2~3.3V，这与传统的草酸亚铁分解法在同样的条件下所得样品具有可比性。

Generally, only two to four charge/discharge cycles would be needed for full activation and the second cycle exhibits the highest rate of increase of discharge capacity and plateau potential.

由于电极电位在电流方向上存在迟滞现象，所以不能通过采用小电流充放电曲线方法来近似测量镍电极的可逆电极电位。

Charge/discharge results revealed that one potential plateau at about 0.22 V is observed in all cases in the first cycle, and is shifted to 0.4 V in the second cycle. There appears no obvious decreasing for gravitational specific capacity after 70 cycles for Sn-Co alloy on rough copper foil, which is better than that of Sn-Co alloy on smooth copper sheet.

充放电测试结果表明，光滑铜片和粗糙铜箔上电镀制得的锡钴合金在首次放电过程中均在0.22 V附近给出一个较长的放电电位平台，并在随后的循环中逐渐正移至0.4 V附近。

It is considered that link wear speed on seal surface is proportional to the contacting pressure. The impacting of valve disk on valve seat is the important reason of abrasive wear, and the relative motion of disk is a main reason for errosion wear of pump valve. The cycles per minute is an important factor to influence the valve motion and the impact force.

结果表明，泵阀密封面联接磨损的磨损速度与密封面上的接触比压成正比，泵的冲次是影响阀盘运动规律及对阀座产生冲击的重要因素，泵阀产生磨粒磨损和疲劳磨损的主要原因是泥浆、阀盘和阀座的冲击，冲蚀磨损导致泵阀的刺蚀。

However, as the name（read－only memory）implies, CD disks cannot be written onorchanged in any way.

然而，正如其名字所指出的那样，CD盘不能写，也不能用任何方式改变其内容。

Galvanizes steel pallet is mainly export which suits standard packing of European Union, the North America. galvanizes steel pallet is suitable to heavy rack. Pallet surface can design plate type, corrugated and the gap form, satisfies the different requirements.

镀锌钢托盘多用于出口，替代木托盘，免薰蒸，符合欧盟、北美各国对出口货物包装材料的法令要求；喷涂钢托盘适用于重载上货架之用，托盘表面根据需要制作成平板状、波纹状及间隔形式，满足不同的使用要求。
