预先处理

The method which is composed of pre-impregnating in soaker, painting coating on the surface of carbon/carbon composite, and solidifying the coating, was first used for the preparation of a good anti-oxidation coating on the composite.

摘 要：采用在C/C复合材料基体表面预先浸涂浸渍剂，再涂刷涂层并进行涂层固化处理的工艺方法，可制备出抗氧化性能良好的涂层。

The results obtained are as follows:(1) injection of 50, 100, and 200 nmol/kg adenosine into the renal artery increased the renal afferent nerve activity in a dose-dependent manner with unchanged arterial pressure;(2) pretreatment with 8-cyclopenthl -1,3-dipropylxanthine (DPCPX, 160 nmol/kg), an adenosine A1 receptor antagonist, partly abolished the effect of adenosine; and (3) pretreatment with a nitric oxide synthase inhibitor N w-nitro- L -arginine methylester (L -NAME, 0.1 mmol/kg) significantly enhanced the ARNA response to adenosine.

结果表明：(1)肾动脉内注射50， 100和200 nmol/kg腺苷可呈剂量依赖性地兴奋肾神经传入纤维的活动，而动脉血压不变。(2)肾动脉内预先应用选择性腺苷A1受体阻断剂DPCPX (160 nmol/kg)，可部分阻断腺苷对肾神经传入纤维的兴奋作用。(3)静脉应用一氧化氮合酶抑制剂 L -NAME(0.1 mmol/kg)预处理，延长并增强了肾神经传入纤维对腺苷的反应。
