The equilibrium structure and dissociation energy of TF molecule at the ground state are calculated and optimized using quantum chemistry methods CCSD(T)and QCISD(T) at the 6-311++G** and cc-pvdz basis set.
利用其对TF分子的基态进行优化计算,使优化的平衡间距分别为0。
Objective To assess the clinical value of 99mTc-tetrofosmin (99mTc-TF) planar and single-photon emission computed tomography (SPECT) in comparison with ultrasonography in the diagnosis of breast cancer.
目的探讨99mTc-tetrofosmin(99mTc-TF)平面显像、断层显像诊断乳腺癌的临床价值,并与超声检查做比较。
