The image you uploaded appears to discuss the temperature-resistance relationship of an NTC (Negative Temperature Coefficient) thermistor. The formula in the image describes the connection between resistance \( R_T \) at temperature \( T \) and other constants:

\[
R_T = R_7 e^{B \left( \frac{1}{T} - \frac{1}{T_7} \right)}
\]

where:
- \( R_T \) is the thermistor's resistance at temperature \( T \) (in Kelvin),
- \( B \) is the thermistor's material constant,
- \( R_7 \) is the resistance at a reference temperature \( T_7 \) (likely at 7°C in this case).

The table lists temperature \( T \) in °C and corresponding resistance values \( R \). The task seems to involve calculating certain parameters (likely using Excel), such as determining \( B \), and perhaps finding values like resistance or temperature at other points by fitting the exponential relationship.

To clarify:
- You may need to convert temperatures from °C to K (by adding 273.15).
- Fitting this data to the provided equation can help find the unknown constant \( B \).

Would you like help setting up the calculations, or do you need assistance with specific steps, like finding \( B \) or creating the exponential fit in Excel?

### Follow-up questions:
1. Do you need help calculating the \( B \)-value based on this table?
2. Are you asked to find the resistance at temperatures not provided in the table?
3. Would you like a step-by-step guide to using Excel for this problem?
4. Should I explain how to convert the temperatures to Kelvin for the formula?
5. Is there a particular formula-related step you're unsure about?

**Tip:** When handling exponential data like this, it’s often helpful to plot the logarithm of the resistance versus \( 1/T \) (in Kelvin) to linearize the data and make it easier to fit.

已知NTC型热敏电阻的电阻-温度特性,在一定范围内满足以下关系: RT = R7 * e^(B*(1/T - 1/T7)), 式中温度采用为开尔文温标 (K)。B为热敏电阻的材料常数, R7 和 T7 分别是温度7和7的电阻值。表中给出了温度 T (°C) 和对应的电阻值 R (Ω)。 计算不同温度下的电阻。

Learn how to calculate the resistance of an NTC thermistor at different temperatures using the exponential formula RT = R7 * e^(B*(1/T - 1/T7)). This problem involves thermodynamics and exponential functions, suitable for students in engineering and physics.
