T: \(q_{T}=q_{T}\left( \text {Test 1, Test 2} \right)\) \(\frac{\partial T}{\partial n} = 0\) \(q_{T}=q_{T}\left( T_{\infty }=20^\circ \text{C} \right)\) \(q_{T}=q_{T}\left( T_{op} \right) ^{\text{a}}\)
\(P_G\): \(P_{G}=0.1\) MPa \(\frac{\partial P_{G}}{\partial n} = 0\) \(P_{G}=0.1\) \(P_{G}=0.1^{a}\)
\({\tilde{\rho }}_{V}\): \(q_{v}=q_{v}\left( {\tilde{\rho }}_{V,\infty }\right)\) \(\frac{\partial {\tilde{\rho }}_{V}}{\partial n} = 0\) \(q_{v}=q_{v}\left( {\tilde{\rho }}_{V,\infty }\right)\) \(q_{v}=q_{v}\left( {\tilde{\rho }}_{V,\infty }\right) ^{\text{a}}\)
