The hemolytic activity was mg2 + - dependent and heat - sensitive , and was abrogated by treatment with rabbit anti - human c3 serum , zymosan , methylamine , hydrazine , and phenylmethylenesulfonyl fluoride ( pmsf ) 文昌魚體液對兔血紅細胞的溶血活性在受到酵母聚糖、甲胺、肼、 pmsf 、 edta 、兔抗人補體3抗血清處理時,溶血活性消失。

Otsuka chemical , the leader in the hydrazine industry , has been pursuing possibilities of hydrazine compounds for half a century , and is offering various functional hydrazine derivatives 大冢化學致力于功能性肼衍生物的開發,從早期的水合肼鹽,到偶氮類發泡劑和聚合引發劑,不斷追求水合肼、肼的衍生物和多元環化合物的新功能。

Conclusions : the findings reported here are consistent with our previous results for lung cancer mortality ; our new results suggest that exposure to hydrazine increases the risk of incident lung cancers 結論:本篇報告的發現與我們先前對于肺癌死亡率的結果一致,新的結果顯示聯氨的暴露會增加肺癌發生率的風險。

The reason of these improvements are discussed as a base of lower down the power level without the debasement of performance and the alter of propellant by hydrogen or hydrazine 為今后進一步在確保性能的前提下降低發動機功率以及以氫氣、氮氣混合或者肼作為推進劑的電弧加熱發動機的探索和研制奠定了基礎。

Nanosize silver particles have been prepared by reduction of aqueous solution of agno3 in the presence of polyvinylpyrrolidone , ethanol and de - ionized water , hydrazine hydrate was used for the reduction 摘要采用聚乙烯吡咯烷酮、無水乙醇和去離子水混合溶液,利用水合肼還原硝酸銀制備納米銀粒子。

The impact flash may have been caused by the thermal emission from the impact itself or by the release of spacecraft volatiles , such as the small amount of hydrazine fuel remaining on board 撞擊的閃光可能來自撞擊本身產生的熱噴發,也可能是飛船上的揮發物,如剩余的少量肼燃料。

Background : animal studies suggest that hydrazine is a lung carcinogen , but human studies have been rare , rather small , and limited to cancer mortality 背景:動物研究發現聯氨可能為肺部致癌物質,但人類研究相當少,且局限于癌癥死亡率之調查。

If they are accumulated to a considerable level , elimination of these ions can be carried out by an addition of strong reducing agent such as hydrazine 如果他們累積到相當大的水平,要除去這些離子是可以透過增添像聯氨這樣強的還原劑來完成。
