The results indicate that the initial deviations of the joint positions match normal probability density function limited in the range of double mean variance.

随机缺陷分析方法中假定结构每个节点的位置偏差符合二倍均方差范围内的正态概率密度函数是可以接受的。

The results showed that the number of chromosome, which was from the cultured seedlings of meristem tip and the rank seedlings of meristem tip, was not altered, both the number were 2n=16,the hereditary stability of callus and regeneration plant was poor; and the variation percentage of chromosome in callus was 43.4%, among which haploid accounted for 6.7%, triploid accounted for 2.5%,tetraploid accounted for 10%,pentaploid accounted for 4.2%,hexaploid accounted for 3.3%,septuploid accounted for 4.2%,octoploid accounted for 3.3%,dysploid accounted for 9.2%;the chromosome variation percentage of differentiation seedlings derived from callus was11.7%,among which haploid was 6.7%,triploid accounted for 1.7%,tetraploid was 3.3%.

结果表明，茎尖分生组织培养的幼苗及丛生苗遗传稳定，其染色体未发生倍性变异，均为2n=16；愈伤组织及其再生苗遗传稳定性较差，愈伤组织染色体数变异率为43.4%，其中单倍体占6.7%、三倍体占2.5%、四倍体占10%、五倍体占4.2%、六倍体占3.3%、七倍体占4.2%、八倍体占3.3%、非整倍体占9.2%；愈伤组织分化苗染色体变异率为11.7%，其中单倍体占6.7%，三倍体占1.7%，四倍体占3.3%。

The proposed method has the capability of predicting the performance of condenser including threedimensional effects due to the change of cooling water temperature and the multiple tube paths arrangement. The proposed algorithm is more suitable to the condenser of multiple tube-paths than existing method. The proposed method is applied to a N11220-1 condenser to demonstrate its predictive capability, the results indicate that condensation rate of each bay and the air concentration at gas offtake is quite different, which can not be predicted by two-dimensional method.

对N11220-1型凝汽器的一个实验工况的模拟表明，该方法的热流密度计算结果与实验结果吻合良好，证明方法是有效的，模拟结果还表明，由于冷却水温度沿程变化，沿轴向各个汽室的冷凝量和抽气口的空气浓度均有明显不同，而目前国内外仍在使用的二维模型程序无法考虑这些影响，计算精度较差。

Prevalence of PVR and retinal detachment were observed by direct ophthalmoscopy, B-scan uttrasonography and pathology study.

的剂量比对照组低，联合用药组上清中几－6、IL－8和TrNF－Q 比其他各组均低，方差分析显示各组之间具有显著性差异。

Optical path difference varies from point to point.

根均方 。光程差OPD从点到点发生变化。

Second: Comparetive study of ordinary X-ray film, CT and 3D-CT in the jaws fractures. Ordinary X-ray film, CT and 3D-CT was performed in 61 cases of jaws fractures. The diagnosis of these three imaging methods was compared with each other and with the operation findings. The result shows that the fractures in body and angle part of mandibal could be shown excellently by all these imaging methods. 3D- CT is the best method in showing the mandibular fractures. Ordinary X- ray film is poor, and the accuracy of CT and 3D-CT is similar in showing the macxillary fractures.

二。颌骨骨折的常规X线、CT和三维CT对比研究：通过对61例不同类型的上、下颌骨骨折常规X线、CT和三维CT显示情况的对比分析，同时与手术结果相对照，结果表明对下颌骨体部和角部的骨折三种影像学检查均显示准确；对下颌骨髁状突骨折的显示三维CT优于CT和常规X线；对上颌骨骨折的显示常规X线显示较差，CT和三维CT显示准确率相似。
