均差

Results :Satisfactory facial appearance was achieved in all the patients . Results showed that the repeatability was 100% when error tolerance was 3.5 mm. If tolerance was set at 2 mm, the repeatability was 97.8%.The biggest difference occurred in ramous area.

结果：5例患者均获得满意的术后形态，在差值分析分析中，设允许误差为2mm，真实术后与虚拟手术的吻合程度为97.8%；设允许误差为3.5mm，两者吻合程度为100%；最大差别产生的区域在双侧升支。

The femoral circumflex arteriography of the normal leg was done in 8 patients, and three of them were simultaneously done in a postion of internal rotating of straight leg. Results Comparison with the arteriographic findings in absence of traction, all retinacular arteries but inferior arteries were depicted few branches and less femoral head perfusion in all 9 patients, especially in that of medial femoral circumflex arteriography, as hip joint was tractating in neutral position with the same speed and volume of injecting contrast medium and, the veins were demonstrated poorly or delayed.

结果同一血管部位，同等对比剂注射流率、总量造影，与中立位无牵引状态下造影所见比较，9例患髋中立位牵引时，除外下支持带动脉，所有未损伤的支持带动脉均有不同程度闭塞，相应股骨头颈部灌注不佳或几乎无灌注，静脉显影延迟或显示不清，4例牵引力由3kg增至5kg时，上述改变更为明显；5例患髋维持伸直内旋位时，所有支持带动脉尤其细小分支未见明确显示，股骨头灌注差或未见明确灌注，改变甚于牵引时；2例正常髋内旋位时造影改变类似。

It is concluded that the accuracy of ST/HR hysteresis is definitely better than STend, STrec and ST/HR index because it actually represents the average difference in heart rate adjusted ST segment depression between the exercise and recovery phases regardless of the magnitude of heart rate decrease during the recovery phase

ST/HR hysteresis反映了心率校正后的运动期与恢复期的ST段差值的平均值，因而比STend、STrec和ST/HR Index三个指标均准确，值得临床推广。

Postmenopausal women had lower aerobic capacity compared with premenopausal women and age-matched males, which may correlate with endothelial dysfunction, impaired functional sympatholysis, and insufficient muscular oxygenation. Exercise capacity is associated with cardiovascular risk factors, such as lipid profile, C-reactive protein, and body mass index.

与停经前女性或同龄男性相比，停经后女性的有氧耐力明显减少，运动时的血管内皮扩张反应与功能性抗交感反应下降，使周边血管在运动时扩张能力较差、肌肉血流与含氧量低，均是导致运动能力下降的因素。

Results:① Compared to cystadenomas, the tissual MVD was significantly higher in bordline cystadenomas, but signicantly lower than cystadenocarcinomas.

结果：①良性、交界性及恶性浆液性卵巢肿瘤组织中MVD值呈逐渐增高趋势，MVD值分别为7.8±2.4、17.5±3.3及27.6±7.5，三者之间差异均有显著性；浆液性卵巢癌不同的组织学分级中MVD差异有显著性，高、中及低分化组织中MVD值分别为18.3±3.4、24.2±3.1及32.3±6.4，分化程度愈差，MVD值愈高；浆液性卵巢癌不同的FIGO分期中MVD差异有显著性，Ⅲ-Ⅳ期的MVD值高于Ⅰ-Ⅱ期的MVD值，分别为28.9±4.7及22.0±4.7。

Compared to cystadenomas, the tissual VEGF and bFGF expressions were significantly higher in bordline cystadenomas, but signicantly lower than cystadenocarcinomas.

VEGF、bFGF的表达在浆液性卵巢癌不同的组织学分级中差异均有显著性，组织分化愈差，二者的表达就愈高；在高、中及低分化组织中VEGF的表达分别为30.9±16.2％、48.0±18.4％及62.1±21.3％，各组间差异有显著性；bFGF的表达分别为25.0±17.7％、37.9±17.2％及47.7±13.1％，各组间差异有显著性。

Results: Compared with normal subjects, the wave patterns of obsessive-compulsive patients were unstable; the frontal wave variation and dissymmetry between the two sides was 63.9%; the N2 and P3 latency was prolonged; the P2 and P3 amplitude was decreased; the P3 topograph...

结果 ：与正常对照组(33人)相比，强迫症患者波形稳定差，2 3例(6 3 。9%)出现额叶波形变异或两侧不对称；N2、P3的潜伏期明显后移；波幅下降；36例患者的P3地形分布图均失正态分布，正常顶区高功率消失。

The results were summarized by variance analysis and correlation analysis, the diversity reached significant positively correlated level of varieties carotene, polysaccharide,γ-am1nobutyric and crude fibre content, but the diversity bad- not reached significant positively correlated level of varieties Zn, Cr and Trigonelline content.

对11个品种肉用印度南瓜主要果实性状进行调查，并对果肉的8种营养成分测定；通过方差和相关分析得出结论：胡萝卜素、多糖、淀粉、γ-氨基丁酸、粗纤维含量在各个品种间差异均达到极显著，Zn、Cr、葫芦巴碱的含量在各个品种间差异不显著。

The growth of plantlets with the height of 1-2 cm and 3-4 leaves was compared on MS basal medium containing various organic compounds, including banana, carrot, potato, coconut water, and tryptone. The result showed that the growth of oncidium plantlets was the best on medium containing banana, potato and tryptone altogether with respect to their plant height, leave number, root number, root length, fresh weight, and dry weight. The next better media were the control and the Banana medium, followed by the Potato medium.

另外取高约1-2公分，带3-4片叶片的分化小苗，培养於含不同浓度有机添加物（香蕉、胡萝卜、马铃薯、椰子水、及tryptone）的半量MS培养基，以探讨最适合文心兰瓶苗生长的培养基，试验结果显示，在同时含香蕉、马铃薯及tryptone三种成份的培养基生长的小植株不论在株高、叶数、根数、根长、鲜重、及乾重均较其他培养基为佳；不含添加物之1/2MS培养基、及含香蕉的培养基次之，而在含马铃薯之培养基较差。

Results Singlefactor logistic regression analyses showed that there were very significant differences in 11 factors between the 2 groups（all P＜0.01）;multiplefactor conditional logistic regression analyses in the 11 factors showed that the main risk factors of psychoactive drug abuse in middle school students were parents' drug abuse,poor performance record,absent from class,violence,selfconscious loneliness and unharmony family relation,the main protective factor was more exchanges between parents and children.

结果 两组自拟问卷单因素Logistic回归分析发现，11个因素有极显著性差异（P均＜0.01）；将11个有显著意义的因素进行多因素条件Logistic回归分析，结果发现影响中学生精神活性药物滥用行为的主要危险因素为父母有药物滥用、学习成绩差、缺课、暴力行为、自觉孤独、家庭关系不和睦，而多与父母交流则为主要保护因素。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
