he fermented medium of Cordyceps sinensis studied is by orthogonal design.The factors of glucose.lactose. potato. silkworm chrysalis.amino acid powder.Table L27(313) is used to test four factors with three levels,the interac.non among the factors is examined as well.The results are treated by analysis of variance.The best medium is seleted that 15% potato.2% glucose.0.8% lactose. 1 % amino acid powder.0.1 % KH,PO.0.1% MgSO.0.1 % ZnSO..

用正交试验法对冬虫夏草菌(CordycepssinensisBerksacc)的发酵培养基进行了研究.考察了葡萄糖、乳精、马铃薯、蚕蛹、氨基酸、复合粉、磷酸二氢钾、硫酸锌、硫酸镁、硫酸亚铁等因素,用L27(313)表安排正因素、三水平并考虑交互作用的正交试验,对上面各因素的添加量分别做了实验,并对实验结果进行了方差分析,确定了合适的发酵培养基.实验结果表明:冬虫夏草菌的深层发酵最佳培养基应该是:15%去皮马铃薯、2%葡萄糖、0.8%乳精、1%氨基酸复合粉、0.1%磷酸二氢钾、0.1%硫酸锌、0.1%硫酸镁.

Hot-dip plated steel was annealed to alloy the zinc plating. The morphology changes from η-and ζ-phase to δ1-phase are found in the coating material after annealing. Homogeneity tests show that the number of impregnation times increases from 5 to more than 10. It is proved that the binding force and corrosion-resistance are improved through annealing. The results of coordinated experiments with respect to five factors shch as dip coating procedure and alloying conditions also show that optimized hot-dip zinc...

Hot-dip plated steel was annealed to alloy the zinc plating. The morphology changes from η-and ζ-phase to δ1-phase are found in the coating material after annealing. Homogeneity tests show that the number of impregnation times increases from 5 to more than 10. It is proved that the binding force and corrosion-resistance are improved through annealing. The results of coordinated experiments with respect to five factors shch as dip coating procedure and alloying conditions also show that optimized hot-dip zinc plating can be obtained by galvanizing the steel in Zn-0. 07% Al plating bath at 450-480℃ and then alloying it at 450-510℃.

钢铁热镀锌后进行退火合金化处理,改变镀层组织结构,促使η相和ζ相向δ1相转变,从而使镀层均匀性试验CuSO4浸渍次数由5次提高到10次以上,且明显改善镀层结合力和耐蚀性.考虑到热镀锌工艺因素和合金化处理工艺因素等进行正因素正交设计,正交试验结果表明,在Zn—0.07%Al镀液中,于450~480℃进行浸镀,然后在450~510℃进行合金化处理,可获得性能优良的热镀锌层.

Objective To investigate the relationship between asthenopia and ammetropia and its treatment. Methods 52 cases with normal vision were studied which included the factors of history, refraction, intraocular pressure, position of gaze and use of the eyes. Results Though their vision were normal, minimal ammerropia existed in all of the 52 cases, minimal astigmatism was more often and women tended to affect the incidence of asthenopia. Conclusion Though asthenopia has complicated clinical symptoms, there are some...

Objective To investigate the relationship between asthenopia and ammetropia and its treatment. Methods 52 cases with normal vision were studied which included the factors of history, refraction, intraocular pressure, position of gaze and use of the eyes. Results Though their vision were normal, minimal ammerropia existed in all of the 52 cases, minimal astigmatism was more often and women tended to affect the incidence of asthenopia. Conclusion Though asthenopia has complicated clinical symptoms, there are some characteristics to be found. Refractive error is one of important factors and others include balance of ocular muscle, simple binocular vision, working with computers, sex, age, health level, etc. Correcting refractive error is one effective method to reduce asthenopia .

目的 观察机关干部有视疲劳症状而视力正常的屈光不正特点,探讨患病原因与治疗原则。方法 调查分析了52例视力在正常范围内患者的病史、屈光状态、矫正效果、眼压、眼位和用眼状况等因素及随诊情况。结果 52例患者视力虽在正常范围,而经屈光检查均有轻度的屈光不正,并以轻度散光居多。视疲劳以轻度和中度为主,女性多于男性。结论 视疲劳虽为一复杂的临床表现,但有一定的特点。其中查找有无屈光不正的因素不可忽略,还有眼外肌平衡,双眼单视功能,电脑前工作强度、年龄和全身情况等多方面原因,但首先排除屈光不正,这是缓解疲劳的手段之一。
