    Observations were carried out both in the laboratory and under natural conditions on the life history of Farcipomyia (Lasiohelea) taiwana (Shiraki). Laboratory rearing methods for the immature stages were established in order to study the metamorphosis of this midge.In the laboratory the midge feeds on suckling mice, newborn albino rats, newborn domestic rabbits, and human blood; and its ovarian development depends on the food,. while no carbohydrate food is taken. After a full bloodmeal, blood digestion and ovarian development are synchronised in the female. When half fed, its ovarian development is normal and maturation of ovary and egg deposition can proceed as usual. Aside from the high degree of gonotrophic harmony, low degree of gonotro-phic harmony also exists in this mLdge.In general, under laboratory conditions, females feeds on blood and deposits eggs twice, and these activities sometimes may increase to four times. Most of the test tube rearing females deposit eggs 2-4 days after blood feeding at 20-34℃. The percentage of egg deposition among these females is 85-98%. The number of eggs laid by each of these females is 24-147 (79.04 in average).All fertilized eggs can hatch, hatching takes place normally in water, and eggs can endure desiccation. Soil must be kept wet in rearing the immature stages, but too much water is mot good for the pupal stage. Larval stages can be reared in separate rearing medium of a single substance (blood powder, liver powder, yolk powder, yeast powder and algae).The length of the developmental stages varies with the changes in temperature and food, when soil is kept moist. In yolk powder medium at 7-20.2℃., 66-84.5% RH, total length from egg to imago is 136-164 days. In blood powder and liver powder mediums at 15:5-25.4℃., 74-83% RH, the periods from egg to imago are 33-63 days and 38-59 days respectively. In yolk powder and yeast powder media at 18-24.6℃., 72-88% RH, they are 29-35 days and 31-44 days respectively. In algae medium at 20-25.2℃., 76-85% EH, it is 14-39 days.

    在重庆地区结合室内、外的情况观察了台湾铗蠓的生活史。台湾铗蠓吸大、小白鼠仔鼠,仔兔和人的血液,碳水化合物在卵巢发育过程中并不需要。雌虫吸取一份充足的血液后,胃血消化和卵巢发育之间是完全一致的。半饱时,卵巢可正常发育产卵。除高级生殖营养外,尚存在着低级生殖营养。 试管饲养下,20—34℃时,多数在吸血后2—4日产卵。产卵率85—98.12%。每雌产卵24—147个,平均79.04个。 受精卵均能孵化,在水内也能正常孵化,卵对干燥具有一定的耐受性。饲育期间,土壤必须保持湿润,多水对蛹期极为不利。幼虫以血粉、肝粉、蛋黄粉、酵母粉和海绵藻为食物。 幼期发育的时间:蛋黄粉培养,在7—20℃,RH66—84.5%时,自卵至成虫为136—164天,血粉、肝粉培养,在15.5—25.4℃,RH74一83%时,自卵至成虫分别为33—63和38—59天。蛋黄粉和酵母粉培养,在18—24.6℃,RH72—88%时,自卵至成虫分别为29—35和31—44天。海绵藻培养,在20—25.2℃,RH76—85%时,自卵至成虫为14—39天。

    By observing with microscope,X-ray and electron probe, determining mechanical properties of treated steel 5CrNiMo,a powder medium for chromomanganesizing is investigated.Influence of different temperature and time on diffusion depth, hardness, wear resistance, hot-fatigue and brittleness of the steel is analyzed. Result showes that the chromoman-ganesized steel possesses a layer with high hardness, low brittleness, high wear resistance and hot-fatigue resistance.This medium was applied on hot working...

Result showes that the chromoman-ganesized steel possesses a layer with high hardness, low brittleness, high wear resistance and hot-fatigue resistance.This medium was applied on hot working dies, and the dies service life could be 2.5—3 times as long as before.

    通过金相、硬度、X射线结构分析、电子探针、耐磨、热疲劳及脆性试验等方法,讨论了5CrNiMo钢的固体铬锰共渗工艺,分析了在不同温度,不同时间的共渗对渗层深度、硬度、耐磨、热疲劳及脆性的影响。结果表明,5CrNiMo钢进行固体铬锰共渗后能获得一定的渗层,该渗层硬度高而脆性小,可有效地提高耐磨及耐热疲劳性能。目前,固体铬锰共渗剂已应用于热作模具,使用寿命提高1.5~2倍。

    Instcad of prescrving Trypanosoma evansi by animai inoculation in tradition, We can preserve it in low temperature refrigerator of -80℃ by using the nutrient solution of 1640 powder medium with FBS and freezing resistancc of glycerinum now.
