Objective To study the pilots ' heart rate variability ( HRV ) characteristic before during and after parallel swing and the possibility of evaluating vestibule vegetative nervous reaction under linear acceleration .

目的观察飞行员在平行秋千摆动前、中、后反映心脏 植物神经调节功能的心率变异性（HRV）特点，探讨以此评价线性加速度 作用下前庭－ 植物神经 反应性的可能性。

The intensity of colour in generative nucleus by using Feulgen reaction was deeper than vegetative nucleus and two sperms forming later . The generative cell and vegetative nucleus gave a positive reaction to PAS stain .

生殖细胞核孚尔根染色反应要比营养核以及后来形成的两个精核的染色深，生殖细胞与 营养核PAS 反应均为阳性。

In the vegetative cells the localization of the reaction particles of acid phosphatase ( ACPase ) was in the food vacuoles or the autophagic vacuoles of different stages while in the resting they formed the vacuolar or spherical bodies .

营养 期细胞中，酸性磷酸酶 反应颗粒分布在处于不同消化时期的食物泡或自噬泡内，在休眠期细胞中酶反应颗粒定位在自噬泡周缘；
