These primer combinations produced a total of 1 119 bands, 229 specific loci (including 54 absent bands, and 175 monomorphic bands). Among them, 983 polymorphic bands, accounting for 88%, were detected. The percentage of identification per primer combination was as high as 100%. The average PPB of 14 foreign cultivars was 35.86% and the average PPB of seven domestic cultivars was 31.51%.

On the basis of neglecting the change of parison dimensions and shape due to swell and sag during parison formation, average temperature distribution of paris...

本文在忽略型坯挤出后由于膨胀和垂伸而引起的型坯尺寸和形状的变化，利用热量平衡原理对挤出吹塑中型坯挤出阶段型坯截面平均温度分布进行了研究，提出了型坯截面平均温度分布的计算公式，其计算结果用实验进行验证。

Dividing disease entities by fixed digits of ICD-9 code is easily performable. This method should be used when the disease entities include about 60% of total inpatients, and geometric mean should be used in calculating average length of hospital stay and average cost.

采用固定位数的ICD-9编码分类方法可操作性较好，分析病种所包括的住院患者占住院患者总数的60%左右较为合适，病种平均住院天数和平均住院费用等指标以几何均数为宜。

Methods 128 cases of long bone fracture were randomly divided into the contrast group of 72 cases treated with the routine open reduction and internal fixation and the experimental group of 56 cases treated with transplantation of periosteal slices of cortical bone at the place of fracture.

方法将 12 8例须手术治疗的四肢长管状骨骨折病人随机分为两组。对照组：5 6例，进行常规切开复位骨折内固定。治疗组：72例，在常规切开复位内固定的同时，于骨折处用锐利的骨刀凿取带骨膜薄层皮质骨植于骨折处。结果治疗组临床愈合时间平均为(12 。7± 2 。4 1)周，对照组平均(2 0 。3± 4 。6 1)周，二者相比有显著性差异(P 。0 5 )。

All emergence index were higher markedly than control group (P.05), besides, the shrimp larvae showed high quality anduniformity, the amount of "OK" brand that was used in every group during cultivation was 48.34%,58.50%,48.81%,and 49.5% less than that of "Bonasse" brand, however, the former had the better larval nursery effect than the latter obviously. It was more recommendable that using the compound blended with formulated diet of 80% microencapsulated diets of "OK" brand and 20% rotifera than only using microencapsulated diets of "OK" brand.

另外，在培育过程中投喂欧开牌微胶囊饲料的各实验组其饲料投喂量分别比博尚牌饲料少用48.34％、58.50％、48.81％和49.5％，但其育苗效果明显好于后者。80％欧开牌微胶囊和20％卤虫配合使用培育凡纳对虾幼体的效果比单独使用欧开牌微胶囊饲料培育效果好：前者的出苗率，出苗时平均尾重，平均体长分别高出后者38.73％、利用截欢囊句料培育凡姑对炸幼体苟比软研究25%和7.8%，各项出苗指标也明显高于后者(P 。05)。

Sensitivity experiments showed that mycelial growth of the pathogen was affected by azoxystrobin,with a mean EC50as 0.964 9 μg/mL,ranging from 0.142 8 μg/mL to 1.950 9 μg/mL,and sporangial formation was affected by the fungicide to a greater extent,with a mean EC50as 0.023 9 μg/mL,ranging from 0.001 0 μg/mL to 0.084 4 μg/mL.

Chenopodium album,Solanum nigrum, and Amaranthus retroflexus were very susceptible to the herbicides. Polygonum persicaria and Abutilon theophrasti were relatively less susceptible to the herbicides, and Lycopersicon esculentum was not susceptible to it. The relationship between reduction rates of weed biomass and PPM values of weed leaves 2,4, and 6 days after treatment was established.
