NMDA receptor subunits express weakly at postnatal 7 days (P7),goes up at P14,reaches maximum level at P21,then remains this level until adult. Conclusion Neuronal functional NMDA receptors are composed of NMDA R1 and NMDAR2A in heteromeric configuration in the ventral horn of spinal cord;N MDA receptors may be involved in motor neuron maturation and plasticity during p ostnatal development.

However,it has been shown that these treatment regimens alone cannot inducecomplete tumor regression in weakly immunogenic tumors.

然而，对一些低免疫原性、高恶性的肿瘤，单一的免疫治疗策略并不能达到理想的抗肿瘤效果。

Identical data inequilibrium stats and similar shock-induced reacting flow fields are gained for tworeaction models when projectile velocity is 3km/s. In this case, the molar fraction ofdissociated methane is so small that the frozen flow or a very simple reaction modelcan well describe the flow field of weakly shocked methane. As projectile velocityincreases, molecular methane is readily dissociated and some stable products are formed. Only do the numerical results of the 40 reactions involving13 species approach to the corresponding experimental results.

计算表明，当飞片速度低(3km／s)时，两种反应模型给出冲击状态参数的结果基本一致，因为这时甲烷气体冲击波后的成分变化很小，说明可以用更简单的化学反应模型描述高温甲烷的化学反应过程；当飞片速度增大时，甲烷分子迅速的离解，反应产物容易形成稳定的化合物，只有13组元40反应模型的计算结果才能与实验结果接近。
