When the gas flux is constant, the ratio of reduced resistance is improved with the increase of the water stream velocity. However, the relationship between the gas flux and the ratio of reduced resistance is more complex. When the water stream velocity is constant, if the gas flux is small in contrast, the effectiveness of reduced resistance is not obvious. But when the gas flux increased, the jetted gas will form """"archform"""" which will augment the shape resistance. In this condition, resistance could not be reduced and could even be increased, if the gas flux continues to be increased. So that there needs setting a baffle called step, which introduces the jetted gas into the turbulence boundary layer. In this case, the shape resistance may be fairly great. Besides, the waterline of model has also some effect on the ratio of reduced resistance, which acts on the size of wave. If waterline is deep, the wave could not affect the deployment of microbubble layer, so there is almost no effect on ratio of reduced resistance. However, the wave would affect distributing of microbubble layer under the model so that the gas could leak out from the two sides of model and directly affect the ratio of reduce resistance if the waterline is very small. Whether installing the dashplate or not has also the great influence on the effectiveness the ratio of reduced resistance. From the results of experiment, conclusion is that adding dashplate will greatly improve the effectiveness of reduced resistance.

当喷气量一定时，水流速度增大，减阻率提高；喷气量与减阻率之间的关系比较复杂，速度一定时，如果喷气量较小，减阻效果就比较差，但当喷气量增大的话，喷射出的气体就会形成一个&拱度&，增加了船模的形状阻力，在这种情况下最好采取断阶喷气，把气体引入到湍流边界层中，在这种情况下，船模的形状阻力比较大；船模的吃水对减阻率也有一定的影响，主要表现在波浪大小上，如果吃水较深，波浪影响不到微气泡层的分布，对减阻率不会造成太大影响，如果吃水较浅，波浪就会影响到微气泡层在船模底部的覆盖情况，可能会有部分微气泡从船模两侧泄漏，这样就直接影响到了减阻效果；是否安装压浪板，对减阻率也有较大的影响，从试验结果可以看出，在船模尾部加设了压浪板时，减阻效果明显得到改善。

The measurement results show that the intensity increases rapidly with discharge voltage at a lower voltage range, but the speed slows at the higher voltage range, for constant gas pressure of 130 Pa; and the intensity increases backwardly with gas pressure at constant discharge voltage of 6.4 kV.

The effective stimulating sites were indentified by defensive cardiovascular response and other components of defence reaction evoked by 3 s trains of rectangular cathodal pulses (100Hz, 0.5ms pulse duration, 70 -150μA intensity for dPAG and 150-250μA for PF) delivered from a programmed multichannel constant current stimulator. The responses included an increase in blood pressure and heart rate, pupillodilation and an increase in the rate and depth of respiration. Currents of 1Hz, intensity of 100- 150μA for dPAG and 200-250μA for PF were used to observe the effect of the stimulation of them on RVLM neurones. The deep peroneal nerve and superfacial deep peroneal nerve were carefully separated, and put on a pair of stimulating electrode respectively, Both nerves were stimulated with constant rectangular pulses of 1Hz, 0.5ms duration and 300μA current intensity to see their effects on RVLM neurones. The baro-and chemo-receptors were activated by the intravenous injection of phenylephrine or 0.208 M NaH2PO4. The degree of convergent inputs to individual RVLM neurone was studied by the stimulation of the sites mentioned above. It was found that neurones about 61.4%(27/44) and 35.3%(6/17) received convergent inputs from three and four places respectively.

过去的研究主要集中于整体水平，利用电刺激或化学刺激RVLM神经元，观察对血压、心率及交感活动的影响，并对影响心血管交感活动的神经递质进行了广泛探讨，积累了大量资料；在神经元水平，主要研究刺激脑内核团、外周神经、化学感受器及压力感受器等对RVLM神经元放电的影响和某些神经递质影响神经元活动的机制、然而，对RVLM神经元如何整合不同信息、其可能突触机制等研究得较少，本互作拟采用在体细胞内、细胞外记录电活动与微电泳，结合中枢核团及外周神经电刺激等方法，对RVLM神经元在不同状态下的整合作用规律与可能机制进行初步探讨，为进一步了解这一复杂的整合过程提供新的理论依据。

So we adopted the isotope marking method in order to know the distribution of BBP in male and female mice. The result indicated 〓H-BBP presented the first-order kinetics and matched the open two-compartment model. Distributional half-life was about 20 minutes and eliminable half-life was about 6-7 hours. As α(the speed constant of distributional phase) was about ten times β(the speed constant of eliminable phase), this compound had a fast distribution and a low elimination.
