从一些技术参数来说，单柱拉力度机的测试的力值是不同与双柱型的。一般来说，双柱型的电池片拉力强度比单柱型的力值要高出许多。当然在价格方面，双柱型的电池片拉力强度比单柱型的也要贵。
In terms of some technical parameters, the force values measured by Single-column tension tester are different from those of double-column tension tester. Generally speaking, the tensile strength of the two-column battery is much higher than that of the single-column battery. Of course, in terms of price, the tensile strength of the two-column battery is also more expensive than that of the single-column battery.
虽然单柱拉力机与双柱拉力机有很多方面的差距，但是用户选用拉力试验机时，还是要选择适合自己的，经济型的。
Although there are many differences between single-column tension machine and double-column tension machine, when users choose tension testing machine, they still need to choose their own, economic type.
