免维护性能利用阴极吸收式密封免维护原理,气体密封复合效率超过95%,正常使用情况下失水极少,电池无需定期补液维护。 长寿命 采用添加稀土元素的铅合金制造板栅,降低了充电过程中板栅的膨胀和气体的析出;放射状板栅结构设计,大大降低内阻、提高电流疏导效率。 2.绿色环保 转接式极柱/端子设计,改良传统直通式极柱/端子...
The lack of compound forming tendencies between Fe, the primary alloying constituent of HT9, and SbNd is elucidated through density functional theory (DFT) calculations on enthalpy of mixing, aligning well with the experimental observations. The strong binding of Nd with Sb appears to be favorable...

Sedimentary rocks from the southeastern Canadian Cordillera varying in age from Mid-Proterozoic to Triassic have been analysed for their Nd isotopic composition. ε Nd(T) values range from +1.5 to −17.2 and Nd model ages T DM(Nd) vary from 1.00 to 2.32 Ga, much in excess over their str...
3.BNd和Nd是不同核素,A项错误;1 mol Nd原子的质量约为140 g,一个原子的质量约为 g,B项正确Nd原子的中子数为80、质子数为60,二者之差为20,C项错误;元素的相对原子质量是根据该元素的各种天然同位素的相对原子质量和所占的物质的量分数算出的平均值,因此14 g钕元素对应的钕原子的物质的量不一定是0.1 mol...
