The results indicated that:(1) There was a distinct difference in the same syllogistic inference(MP、DA、AC、MT)of three concrete propositions and in every concrete proposition s four syllogistic inferences(MP、DA、AC、MT).

结果表明：(1)对同一年级而言，不同内容的条件命题的相同推理(MP、MT、DA、AC)之间表现出显著的差异；对不同年级而言，相同内容的条件命题的四种推理之间也存在显著的差异。

The corrosion fatigue crack growth and near-threshold characteristcsof high tensile steel HT60 were investigated by using the compact specimens underexposure to synthetic sea water. The da/dN vs △K_ relation in air may be conser-vetivel estimated for that in sea water. In the high △K region with high stressratio, owing to the acceleration of crack growth promoted by stress-induced dissol-ution, the crack opening stress intensity factor K_ represents only the result ofcrack surface in contact with corrosion products, so as to give an overestimation ofK_ at crack tip.

对高拉力钢HT60的腐蚀疲劳裂纹扩展特性和门槛值区域特性，采用紧凑拉伸试件在人工海水中进行了实验和研究，结果表明：在空气中的da/dN与ΔK_关系可以作为在海水中的da/dN与ΔK关系的一个偏保守的预测；在高应力比的高ΔK区域，由于应力诱起溶解促进了裂纹扩展的加速；该裂纹开口应力强度因子K_仅反映了裂纹表面同腐蚀生成物接触的结果，从而导致了K_在裂纹尖端的偏大的估计结果。

Test results show that its yield and purity are 92.2% and 99%,respectively. The arricultureal production experimental results show that the (DA-6) can promote the vegetable growth and abloom and can increase the output of production.

近几年来，国内外投入了大量的人力物力对DA 6的合成进行了研究[8，9]，但多数方法存在回收率低，原料缺乏，成本高和设备条件苛刻等缺点，这些严重影响了DA 6的工业化生产和在农业上的推广应用。

Moreover,it was demonstrated that the threesubstances,E,DE and DA,increased dramatically and quickly after LPS treatment.Also,it was revealed that the changes of three substances were more quickly than thechanges of the above mentioned APPs during the same LPS treatment.Thesesuggested that the three substances existed as neurotransmitter.The presence and thechange of the CAs in amphioxus after treated with LPS indicated the evolutionaryexistence of CAs and acute phase response in the protochordate lineage.

第四，我们用高效液相色谱法(High Performance Liquid Chromatography，HPLC)，探讨了LPS感染文昌鱼儿茶酚胺类神经递质的变化，优化了同时测定文昌鱼体液中NE、E和DA三种CAs的HPLC方法，并首次发现，文昌鱼体液中同时存在NE、E、和DA三种CAs物质，其中，E在文昌鱼中首次报道，这三种物质在LPS感染文昌鱼后浓度升高非常明显，与同期的APPs相比变化更为迅速，也体现了神经递质的主导作用，文昌鱼的CAs系统也具有了类似脊椎动物CAs系统的功能，可以初步判断CAs系统的进化源头由脊椎动物可推回到头索类。

However,all of the DA releases during 60,90,120min global ischemia were significantly higher than that before ischemia. The abnormal release of DA from ischemic striatums were significantly inhibited by L-NNA.

结果：大鼠半球缺血30分钟时，纹体DA的释放形成高峰，其后逐渐下降，但都高于缺血前释放量。L-NNA能明显抑制缺血时纹体 DA的不正常释放。

The crack growth rate da/dt of 840D wheel web is of great dispersion,which mainly roots in dispersion of wheel load.

840D车轮辐板孔裂纹扩展速率da/dt具有很大分散性，其分散性主要来源于车轮载荷分散性，可用da/dt=Q.a(a≤35mm时)来表达，裂纹扩展参数Q代表了da/dt的分散性。
