CT perfusion images can visually show different traits of Hemodynamics of hepatic Benign and Malign pathology; No matter what background, various parameters of hepatic tissue around malign lesions had significant difference with far-end liver tissue, while various parameters of hepatic tissue around benign lesions had no significant difference with far-end liver tissue; Allopatric efficiency of hepatic Malign pathology distinctly went up with hepatocirrhosis background;Various parameters of hepatic Benign and Malign pathology had no significant difference and differential significance were no significant.

灌注参数图像能直观显示肝脏良、恶性占位性病变血流动力学的不同特点；无论在何种背景下，恶性病变灶周组织与远端肝组织各同种参数间有显著差异，而良性病变灶周组织与远端肝组织各同种参数间无显著差异，以上特点可以鉴别肝脏占位性病变的良、恶性；肝硬化背景下，恶性病变的发生率明显增高；正常肝组织背景下，良、恶性占位病变组织灌注参数间无显著差异，鉴别诊断意义不大。

However, experiment indicate that the result of the detection method is inaccurate and anamorphic.

本文讨论了双板分动式侧滑台对轴间侧滑量的检测，在假定条件下，通过数学计算可求出轮间和轴间侧滑量，但实验结果却表明这种检测方法测量结果重复性差、失真较大。

After the carboxymethylation,the solubility of pachyman in the water was significantly increased,its β-D-glucan characteristic absorption peak at 890 cm-1 became weak obviously,and its methylene vibration absorption peak and CO antisymmetrical stretch vibration absorption peak appeared at 1 333 and 1 606 cm-1 respectively,which indicated that the carboxymethylation succeeded.The analysis of AFM results showed that CMP molecules existed in different morphology under different solution conditions,and that the concentration,ionic strength and solvent physical chemistry characteristics of polysaccharide solution had effects on the CMP chains conformation and the action mode between different molecular chains.The phenomena were considered to be related to hydrogen bond association and intramolecular and intermolecular electrostatic interactions of CMP.

结果表明：经过羧甲基修饰，茯苓多糖在水中的溶解性显著增加，890 cm-1 处的β-D-葡聚糖特征吸收峰明显减弱，1 333 cm-1 处出现次甲基振动吸收峰，1 606 cm-1 处出现〖JG(〗C〖ZJLX，Y〗O〖JG)〗非对称伸缩振动吸收峰，表明羧甲基化成功；原子力显微镜分析表明：在不同溶液条件下，CMP分子以不同形态存在，多糖溶液的浓度、离子强度及溶剂的物化特性均能对CMP的分子链构象及链间相互作用形式产生影响，推测可能与CMP分子内、分子间的氢键缔合及静电作用有关，CMP分子与云母基底间的吸附及静电作用也会对CMP的分子链构象及图像质量产生影响。

The index (Gst=0.5284) presentes that 52.84% molecular variation existes among subpopulations, 47.16% existes within subpopulations. There are changes of genetic differentiation from 0.0000 to 1.0000. In addition, the gene flow of Aristida pennata populations is 0.4426, which suggests relative limited gene flow may be one of important factor influencing on the genetic structure of the species.

亚种群间的基因分化系数为0.5284，即有52.84％的遗传多样性存在于种群间，有47.16％遗传多样性存在于种群内，各位点的遗传分化程度差别较大(0～1.0000)，其基因流为0.4462，不足以防止漂变引起的种群间的遗传分化。

The percent of atresic follicular increase with dosage rising (P.05).The result of expression of Bax and Bcl-2 showed that the Bax expressed widely in every groups, and it enhanced with dosage, there is extreme significant difference between experiment group and control group (P.01),there is not difference between withdrawal 48 hours and 96 hours.

免疫组化法检测Bax和Bcl-2蛋白表达，结果Bax在各组普遍表达，并随镉剂量的加大而表达增强，实验组与对照组间差异极显著(P.01)，48h与96h两时间段间无差异；Bcl-2则普遍表达较弱或不表达，各组间无显著性差异。

In order to direct the construction of plant germplasms by elucidating the relatives among plants at the level of gene, CYP86MF gene analogues from 11 species of 6 genera in Cuciferae were respectively obtained by PCR strategy using gene specific primers designed from conserved regions of CYP86MF gene reported. Sequence comparisonindicated that the similarities among the genes at nucleotide level were over 80%, and the similarities at amino acid level remained above 70%. The differences between the genes at nucleotide and amino acid level between species were 1.0%~ 5.7% and 2.6%~ 7.3% respectively, while those between genera 5.6%~ 22.5% and 7.3%~ 31.2%, respectively. Phylogenetic analysis showed that Brassica was closely related to Raphanus, followed by Rorippa Scop, Arabidopsis Heynh, Capsella Medic orderly, most distantly related to Orychophrogmus.

为了从分子水平阐明十字花科植物间的亲缘进化关系，给植物种质资源的创建提供理论依据，试验根据课题组已报道的CYP86MF基因编码的氨基酸保守区域设计特异引物，运用PCR技术分别从十字花科6个属11个物种中分离克隆到了CYP86MF基因的同源序列，经比较分析，结果表明：这些同源序列的相似性达80%以上，所推导的氨基酸序列相似性达70%以上，且两者种间差异分别为1.0%~ 5.7%和2.6%~ 7.3%，属间差异分别是5.6%~ 22.5%和7.3%~ 31.2%；由氨基酸序列构建的分子系统树可知，在亲缘进化关系上芸薹属与萝卜属较近，其他依次为蔊菜属、拟南芥属、荠菜属，而与诸葛菜属最远。

Between shrub and herb layers ,the difference of each index was not significant The total richness index and Shannon-Wiener index of Phellodendron amurense plantation community were all the highest than those of the other communities.(2) The total richness index of Machilus pingii- Quercus oxyodon evergreen broad-leaved forest community, Alnus cremastogyne-Betula luminifera-Quercus oxyodon evergreen-deciduous broad-leaved forest community and Rhus potaninii- Juglans sigillata- Quercus oxyodon evergreen-deciduous broad-leaved forest community all exceeded 31 .These communities , the dominance species in their shrub layers is Fargesia rufa ,such as Betula luminifera-Rhus chinensis-Quercus oxyodon evergreen-deciduous broad-leaved forest community, Quercus oxyodon-Litsea pungens-Cornus macrophylla evergreen-deciduous broad-leaved forest community, Cornus macrophylla- Acer caudatum var.

Low genetic variation has probably resulted from the refugial nature of these populations since the last glaciation rather than from recurrent pollen dispersal between Chilanshan and Alishan populations of these 2 Chamaecyparis species. Two Hinfl restriction site differences were found in the trnV-trnM intergenic spacer between C. formosensis and C. taiwanensis. Fragment length difference as well as point mutations in the petG-trnP intergenic spacer between C. formosensis and C. taiwanensis were also found.

如此低的遗传变异可能是因为现今之红桧与台湾扁柏族群为冰河期存在之大族群的残留小族群，而未必是花粉散播所提供之基因交流极为频繁所造成。trnV-trnM基因间区间序列在红桧与台湾扁柏两者间有两个HinfI之酶切点之差异，在PetG-trnP基因间区间序列也发现台湾扁柏与红桧之间有限制酶片段长度及其他点突变。
