This is a demo version for Droid Tesla Pro!
Droid Tesla is a simple and powerful SPICE engine(circuit simulator).
Perfect for students new to electronics circuit design and construction,
hobbyist and tinkerers and even seasoned professionals who want a quick,
handy tool to perform electronics circuit design calculations.
DroidTesla simulator solves basic resistive circuits using Kirchoff’s Current Law (KCL)
in much the same way a student in a circuits class would,the simulator systematically forms a matrix in accordance
with KCL and then proceeds to solve for the unknown quantities using various algebraic
techniques such as Gaussian elimination and sparse matrix techniques.
For non-linear components, such as the diode and BJT ,DroidTesla engine searching for the approximate solution by making an initial guess at an answer
and then improving the solution with successive calculations built upon this guess.
This is called an iterative process.DroidTesla simulation uses the Newton-Raphson iterative algorithm
to solve circuits with non-linear I/V relationships.
For reactive elements(capacitors and inductors),the DroidTesla uses numeric integration methods to approximate the state of the reactive elements as a function of time.
DroidTesla offers the Trapezoidal(I'll add a GEAR method later) integration methods to approximate the state of the reactive elements.
Although for most circuits, both methods will provide almost identical results,
it is generally regarded that the Gear method is more stable, but trapezoidal method is faster and more accurate.

这是特斯拉的Droid Pro的演示版本！
Droid的特斯拉是一个简单而强大的SPICE引擎（电路仿真器）。
适合学生的新的电子产品的电路设计和施工，
业余爱好者和能工巧匠，甚至谁想要一个快速的资深人士，
方便的工具来进行电子电路设计计算。
DroidTesla模拟器解决使用基尔霍夫电流定律（KCL）基本电阻电路
在大致相同的方式在电路将类的学生，模拟器系统构成了根据一个矩阵
与KCL然后前进到解决使用各种代数未知量为
技术，诸如高斯消去和稀疏矩阵技术。
非线性元件，例如通过在一个答案作出初始猜测二极管和双极结型晶体管，DroidTesla引擎搜索的近似解
然后改善与在此猜测建连续计算该溶液中。
这被称为一个迭代process.DroidTesla模拟使用牛顿 - 拉夫逊迭代算法
为了解决具有非线性I / V关系的电路。
为反应性元件（电容器和电感器），则DroidTesla使用数值积分方法来近似反应性元件作为时间的函数的状态。
DroidTesla提供梯形（我稍后再增加一个齿轮方法）集成方法近似的活性元素的状态。
尽管对于大多数电路，这两种方法将提供几乎相同的结果，
它通常被认为是，齿轮方法更稳定，但梯形方法更快，更准确。
