| | In the present paper, the thermal death points of the oocysts, the effect of sunlight on sporulation and the effeciency of Bunsen burner for sterilization were studied. "Xanthium-Areca Complex" (Chinese drug) and ginger appeared to have a good effect on the inhibition of both the exogenous and the endogenous development of the parasite. Dilute NaOH (5.%) dissolved off the outer wall of the oocyst within which the spore might still develop. Eimeria stiedae had higher resistance against NaOH than the other sp... | | 用热水处理兔球虫卵囊,其至死温度为:70℃,10秒钟;60℃,30分钟;55℃,60分钟。经55℃处理30分钟者,至少有90%以上的卵囊不会发育。对温度的耐受能力,四种兔球虫(E.perforans,E.irresidua,E.coecicola,E.stiedae)无甚差别。干烘加热对卵囊的作用,和热水的作用一致。用日光照射,经2时半,约有半数的卵囊仍会发育。酒精喷灯喷烧杀灭卵囊的效果不佳。来回喷射涂兔粪液的木板,经5次之后,对卵囊杀灭的效果仍不显著。但直接在火焰上烧烤,半分钟内即可杀灭涂在木板上兔粪液中的全部卵囊。苍槟合剂和羌对抑制兔球虫卵免的发育效果甚佳。此二药用作兔球虫病的治疗亦初步证实其效果颇好。大蒜无抑制兔球虫卵囊发育的作用,同时在治疗兔球虫病上亦完全无效。由上三种药物对比看来,它们对兔球虫内生性发育和外生性发育的抑制作用是一致的。羌(30/130),苍槟合剂,鱼藤精(10%,5%),可湿性含6%丙体666(1%,5%,15%),D.D.T.(5%),来素(5%,10%、15%),盐(30%、饱和),酒精(50%,70%),氢氧化钠(10%),氯化汞(0.000027%),... | | 文摘来源 | | By using the alcohol blast burner a simple and fast method for analyzing tin ore was developed to take the place of the conventional high temperature furnace.The efficiency of various combustion improvers was compared and a feasible measurement method of lead wasput forward. | | 用酒精喷灯替传统的高温炉 ,体现了快速简易 ,并对多种易熔剂进行了对比 ,提出了一种对锡矿砂可行的测试方法。 | | 文摘来源 | | The fluorescence images of flame from alcohol blowtorch burning kerosene were obtained by planar laser induced fluorescence(PLIF)technique with single laser pulse.The positions of hydroxy radial,C 2 and C 3 in the flame can be obviously displayed from the images,besides,the full process of change for the flame structure from ignition to extinction can be observed.PLIF technique provides a powerful tool for investigating flame structure. | | 用平面激光诱导荧光 (PLIF)技术测量了烧煤油的酒精喷灯单脉冲激光诱导荧光 ,由平面荧光图可清晰地看到氢氧基与C2、C3 在火焰中的位置 ,同时 ,也看到了煤油火焰由发生、发展到熄灭过程中火焰结构的变化 ;PLIF技术是研究火焰结构的有力工具。 | | 文摘来源 | |   | | << 更多相关文摘 |
