Maxium valum of axial torque were measured by static eccntric loading test on the instrumented spines at last; Another 8 fresh frozen human cadaveric spinal speciments were used in this biomechanical test, the testing constructs used were:〓vertebrectomy and 〓 discectomy, bone-graft with anterior Kaneda device, mesh-cage interbody fusion device, mesh-cage with Kaneda fixation, mesh-cage with posterior pedicle screw system TSRH.

利用腰椎三维运动分析系统进行生物力学稳定性测试及静态偏心加压极限扭转载荷测试。2）取8个新鲜冷藏的人尸脊柱标本，分别行〓椎体全切，〓和〓椎间盘全切，制作损伤失稳模型，依次实施四种重建术式：髂骨块植入加前路Kaneda钢板固定，钛网椎间融合器植入，钛网和前路Kaneda联合应用，钛网和后路TSRH椎弓根系统联合应用。

Chapter four is about the value and artistic features of his proses.

In conclusion, the experiment was selected four objects of study, including citric acid, malic acid iso-butyric acid and honey material.

本次试验选定柠檬酸、苹果酸、异丁酸和甜蜜素作为试验对象；选定年龄、胎次、产犊日期、体况标准和采食量相近的16头荷斯坦奶牛作为试验动物；以玉米秸秆作为试验日粮；采用四因子、两水平正交试验设计。

The main by-product s and their separation and recovery technologies were discussed for cyclohexanone gas-phase Beckmann rearrangement.

探讨环己酮肟气相Beckmann重排主要副产物及其分离回收方法，研究1-氮杂-2-乙氧基-1-环庚烯、1，3，4，5-四氧吖庚因-2-酮及其同分异十句体等副产物回收利用生成已内酰胺的方法。

Tetraploid induction from double haploid was also studied, and a desirable result has been obtained. Dripping the apical point of plantlets with 0.2% colchicine plus 1.5% DMSO was a suitable treatment with doubling frequency 18.2%.

其中0.2％秋水仙素+1.5％DMSO滴苗处理，效果较明显，加倍频率达18.2％。1％秋水仙素+羊毛脂膏+1.5％DMSO涂抹生长点试验，加倍率为14.0％，由于此法田间工作量小，不失为双单倍体诱导纯合四倍体较好的方法。

Alabama officials say a duck hunter has found the body of one of the four children allegedly thrown from a coastal bridge by their father .

Structures of monomers, dimers and trimers were studied by density functional theory.

借鉴四组分醇体系模型，指出二聚体共存的可能性。

Four cultivars of Azuki bean, Kaohsiung NO.6 (KS6), KS7, KS8 and KS9 were tested for plant regeneration by using explants sections from the epicotyls formed the seeds germinating seven days after planting in the dark.

本研究利用红豆高雄6号(KS6)、高雄7号(KS7)、高雄8号(KS8)及高雄9号(KS9)等四个品种，於黑暗环境发芽生长七天的上胚轴作为培植体。

By utilizing three benezenemulticarboxylate derivatives (H2chdc, H2aip, NaH2sip), we obtain 12 coordination polymers. Especially, compelexes 1 and 2 are based on one-dimensional ···OHInOHIn···chains as building units, while complex 3 is based on double four-ring [In8(μ2-O)4(μ2-H2O)8]16+, complex 4 is based on trinuclear In3(μ3-O)(CO2)6, complexes 11 and 12 are both based on nested bistranded helices.

选择了三类取代苯羧酸配体： 2，5-二羟基-1，4-对苯二甲酸(2，5-H2chdc)； 5-氨基间苯二甲酸(5-H2aip)； 5-磺酸基间苯二甲酸钠盐(5-NaH2sip)和InCl3反应合成了十二个配位化合物：其中1、2以···OHInOHIn···链为构筑单元， 3以双四元环[In8(μ2-O)4(μ2-H2O)8]16+为构筑单元，4以棱柱状三核铟In3(μ3-O)(CO2)6为构筑单元，而11、12以嵌套的双股螺旋链为构筑单元。
