太行山猕猴掌（跖）骨残损标本复原回归分析

[目的]探讨建立掌骨和跖骨的残缺标本推断掌骨和跖骨整体指标的回归方程。[方法]选用成年太行山猕猴35例（掌骨13例,跖骨22例）,按测量最大长度的方法进行测量,将所得数据用SPSS13.0软件进行相关和回归分析。[结果]建立了掌骨和跖骨整体指标的一元线性回归方程10个,对方程检验有统计学意义。[结论]所得的回归方程可用于利用掌骨和跖骨的残损标本对其整体主要指标的推断,为掌骨和跖骨的复原提供了依据,为进一步对灵长类掌骨和跖骨的研究提供方便,为灵长类的基础研究积累资料。     

约束再生混凝土足尺试件受压应力应变全曲线试验研究

为研究箍筋约束再生混凝土的单轴受压应力应变全曲线,对9个直径为500 mm、高度为1 500 mm的再生混凝土圆形柱进行试验,采用20 000 kN伺服液压试验机进行位移控制加载。试验参数主要为纵筋率、箍筋间距与直径、加载应变速率。试验结果表明,箍筋间距、配箍率对试件延性影响较大。当加载应变速率由0.000 003/s增大到0.003 3/s时,试件的峰值应力增大1.14倍。分析表明,再生混凝土应力应变全曲线与普通混凝土类似,但下降段较普通混凝土陡峭,脆性更为明显。     

Fatigue Analysis of Cement stabilized Macadam with Failure Mechanics

The fatigue life of cement stabilized macadam specimen beams was analyzed through coupling fracture and failure mechanics. The fracture toughness of specimen beams was calculated by finite element method(FEM). And the damage evolution equation controlled by tension stress was given, in which coefficients were back calculated based on the fracture toughness control index using partial fatigue tests data. The life prediction precision of this equation was verified using residual fatigue tests data. It was shown that FEM is effective to calculate the fracture toughness of specimen beams. And the damage evolution equation based on the fracture toughness control index had better life prediction ability comparing with the S N equation. The proposed method can provide a calculation model to predict the service life of practical road structure.

Sonoanatomy of female reproductive organ of Sunda porcupine (Hystrix javanica)

The conventional anatomical study of specimens requires cutting processes which destruct the limited specimens. A non-destructive method, namely an ultrasonography, can be used to assess the anatomical organ information of those specimens. The aim of this research is to analyse the macroanatomy of the female reproductive organ in the Sunda porcupine (Hystrix javanica), using ultrasonographical imaging. In this study, four formaldehyde-fixed reproductive organ specimens of the Sunda porcupine were used. A 10–12 MHz linear ultrasound transducer was utilized to provide an imaging format of both longitudinal and transversal views. Photographic images were then used as comparison with a sonographic image. The results show that the ultrasound image of the Sunda porcupine reproductive organ soft tissue was hypoechoic, the lumen and antrum follicles were anechoic, while atretic follicles and the mons pubis were hyperechoic. Generally, the size of the organ was not significantly different between photographical and ultrasonographical imaging (p > .05). In conclusion, ultrasound images can be utilized for anatomical studies of the Sunda porcupine reproductive organs without destructing the specimen.     

三种型号ABS塑料对制作绵羊支气管动脉铸型标本的影响

探寻适宜于制备支气管动脉铸型标本的丙烯腈-丁二烯-苯乙烯(ABS)铸型剂材料。选用3种不同型号的ABS(PA-749SK、D-120、PA-717CK)对绵羊支气管动脉铸型标本的制作效果进行比较。结果表明,PA-749SK型ABS制备的铸型标本柔韧性和细密度较好;PA-717CK型ABS制备的标本表面光泽度好,但柔韧性和细密度较差;D-120型ABS制备的标本各项性能介于前两者之间。说明受试的3种型号ABS中,PA-749SK型号的ABS更适用于制作绵羊支气管动脉铸型标本,也可以作为其他细小管道的铸型材料被选用。
