Abstract: 经过连续4年的田间试验,比较了2次机采、重度机采、轻度机采和不机采对照等4个处理对白露毛尖茶产量和品质的影响。结果表明:2次机采和重度机采处理显著增加秋季茶芽密度和1芽1叶初展鲜叶产量,显著降低单个芽头的平均重量、长度及符合加工白露毛尖茶芽大小标准的茶芽合格率;符合加工白露毛尖茶芽大小标准的1芽1叶初展鲜叶产量轻度机采处理最高;内含成分分析表明,4个处理秋季1芽1叶初展鲜叶均适宜加工白露毛尖茶,以不机采对照处理感官品质最好。试验表明适度机采可提高秋季白露毛尖茶鲜叶产量,不机采或轻度机采可获得更多优质的白露毛尖茶鲜叶原料。
水轮机调速系统整定参数的计算

电力系统自动化 , 1990,
Abstract: 这篇文章研究了具有良好动态特性的水轮机调速系统的伯德图,并将它们分为二类。同时根据实践中对系统的特性要求,提出了相应的水轮机调速系统整定参数的计算公式。该公式比较简便准确,有利于调速系统的参数选择和试验。
三星堆墓葬与古蜀人的丧葬习俗

天府新论 , 1994,
Abstract: 三星堆墓葬与古蜀人的丧葬习俗傅正初丧葬活动是一种社会文化现象,是每一个民族对灵魂、来生、鬼神等冥世观念的综合反映。它既有社会生活习俗的特点,又有人类特有的处理死者的信仰性质。丧葬形式不仅受到自然环境的制约,而且还受到人们宗教观念的影响。作为一种社会意
黄芩苷体内抗流感病毒作用

中国中药杂志 , 2007,
Abstract: 目的:研究黄芩苷体内抗流感病毒(influenzavirus,IV)作用。方法:采用体内实验方法,对小鼠先预防给药(2d)后感染流感病毒(A/FM/1/47)或先感染流感病毒(1d)后治疗给药的方法观察黄芩苷的抗流感病毒作用。结果:黄芩苷可明显延长流感病毒感染小鼠的存活时间(P<0.01);对小鼠肺内的流感病毒有一定的清除作用,能降低肺内流感病毒的血凝滴度和感染力;减轻小鼠肺内的炎性病变。结论:黄芩苷具有明显的抗流感病毒作用。
杜仲补腰精治疗肾虚腰痛临床研究

中国中医药信息杂志 , 2000,
Abstract: 目的:观察杜仲补腰精对肾虚腰痛的疗效.方法:60例肾虚腰痛患者作为治疗组,30例健康人作为对照组,治疗组口服杜仲补腰精35ml,2次/日,连服30天;对照组口服壮腰健肾口服液35ml,2次/日,连服1个月,治疗期间停用其它一切药物.结果:治疗组的治愈率及总有效率分别为18.33%和93.33%,均高于对照组的10%及73.3%(p<0.05);肾阴虚和肾阳虚两组疗效相当(p>0.05%).该药对肾虚主要症状如腰痛、性功能减退、胫软膝酸、精神疲乏等改善非常明显(p<0

Abstract:
乙烯废碱液作为脱硫剂的湿法烟气脱硫工艺,脱硫效率高,具有良好的经济效益和环境效益。吸收浆液发泡溢流是湿法烟气脱硫过程中较为常见的现象,它对脱硫系统的稳定运行非常不利。乙烯废碱液有一定的发泡趋势,其发泡高度受溶液温度和气流速度的影响。乙烯废碱液中加入消泡剂TEGO-106,消泡效果最好,泡沫高度从27 cm降到2.2 cm,消泡效率为92%。添加TEGO-106消泡剂的最佳浓度为25 ppm。
The process of wet flue gas desulfurization in which ethylene waste alkali liquor was applied as the desulfurization absorbent was beneficial not only to environment but also to the economy for its high desulfurization efficiency. The absorber slurry foaming and overflowing was relatively common in wet flue gas desulfurization processes, which was adverse to the stable operation of the flue gas desulfurization systems. With the certain foaming tendency, the foam height of ethylene waste alkali liquor was affected by both the solution temperature and the gas velocity. Adding the defoaming agent TEGO-106, the defoaming effect was maximized; the foam height reduced from 27 cm to 2.2 cm and the defoaming efficiency reached 92 percent. The optimal concentration of TEGO-106 was 25 ppm.

中国生态农业学报 , 2009,
Abstract: Through a series of 4-year field experiment in hilly tea plantations, the effect of double machine-plucking, heavy machine-plucking, light machine-plucking and no machine-plucking on yield and quality of Bailumaojian tea was examined. The results show that: double and heavy machine-plucking increase bud density and one-leaf and one-bud (fold) yield in autumn. They also remarkably decrease bud weight, length and fitting ratio for processing of Bailumaojian tea. Among the 4 treatments, light machine- plucking has the largest one-leaf and one-bud (fold) yield fitting for processing famous Bailumaojian tea. Chemical analysis shows that leaves of four treatments are all fit for processing famous Bailumaojian tea, while those of no machine-plucking treatment have the best organoleptic quality. The study shows that proper machine-plucking increases yield of Bailumaojian tea in autumn, whereas no or light machine-plucking yields the best quality fresh tea leaf.
