泥灰岩挖方边坡设计研究

阿尔及利亚东西高速公路有大量的挖方边坡位于泥灰岩地层,由于泥灰岩对水很敏感,遇水易软化,强度急剧降低,而且具有一定的膨胀性,因此阿尔及利亚已建和在建高速公路的挖方边坡出现了不少坡面冲刷拉槽和流泥破坏,也出现了少量滑坡.结合东西高速公路的设计施工情况,对泥灰岩边坡稳定分析方法、挖方边坡设计方案进行了论述,并在CCTP要求的防护方案基础上,提出了优化的边坡防护方案.     

HA-D方案治疗急性非淋巴细胞白血病的临床观察

ＤＡ（柔红霉素、阿糖胞苷）和ＨＡ（高三尖杉脂碱、阿糖胞苷）是诱导缓解初治急性非淋巴细胞白血病（ＡＮＬＬ）应用最多的化疗方案,其有效率为５４％～７８％,需２８个疗程才达完全缓解［１～３］。近年来,在ＤＡ和ＨＡ方案基础上加用环磷酰胺或足叶乙甙治疗初治ＡＮＬＬ,疗效进一步提高［４,５］。我们根据ＨＡ方案诱导缓解第８天骨髓穿刺涂片检查的结果,加用柔红霉素（ＤＮＲ）组成ＨＡＤ方案,强化治疗初治ＡＮＬＬ患者１７例。现将观察结果报告如下：对象与方法１　研究对象　初治的ＡＮＬＬ１７例,均为住院患者,其中男１…     

偷猎者倾情拯救座头鲸

座头鲸名列全球第五大巨兽,最大的座头鲸体长超过45英尺,重量达到40吨。尽管体形庞大,座头鲸却是一种非常温驯友好的动物,它们以虾类为食。可是当人类发现它们温柔本性之后,便毫不留情地捕猎。在短短百年间,遍布全球各大海域的座头鲸就被推到了灭绝的边缘。直到20世纪60年代,它才受到了禁猎保护……     

EFFECT OF METHIONINE ENKEPHALIN ON MIGRATION OF MACROPHAGES FROM MICE WITH IMPAIRED LIVER

The increased plasma methionine enkephalin(M- Enk) concentration in patients with liver dis-eases indicates an alteration of the immune func-tion in these patients[1] .Since the effects of opioidpeptide on modulation of immune system in humanbeing and animals under normal condition havebeen revealed,more interest has recently been fo-cused on conditions in stress as liver impairment[2 ] .An attractive trend has emerged in the pastdecadethat in stress some neuropeptides may be secretedand relea…     

与『神六』赛跑

“神州六号“上天那天早晨,急于看现场直播的我下班后便骑上摩托车往家赶. 　　天阴沉沉的,要下雨了.不知道发射现场的天气是否也是这样?虽然路面坑坑洼洼,不过我的车速仍比平时快了许多,此时我只想在“神六“升空前赶回家,因此从某种意义上说,这是我在和“神六“赛跑呀! 　　……     

钢夹层板数值模拟技术(英文)

Sandwich plate systems (SPS) are advanced materials that have begun to receive extensive attention in naval architecture and ocean engineering. At present, according to the rules of classification societies, a mixture of shell and solid elements are required to simulate an SPS. Based on the principle of stiffness decomposition, a new numerical simulation method for shell elements was proposed. In accordance with the principle of stiffness decomposition, the total stiffness can be decomposed into the bending stiffness and shear stiffness. Displacement and stress response related to bending stiffness was calculated with the laminated shell element. Displacement and stress response due to shear was calculated by use of a computational code write by FORTRAN language. Then the total displacement and stress response for the SPS was obtained by adding together these two parts of total displacement and stress. Finally, a rectangular SPS plate and a double-bottom structure were used for a simulation. The results show that the deflection simulated by the elements proposed in the paper is larger than the same simulated by solid elements and the analytical solution according to Hoff theory and approximate to the same simulated by the mixture of shell-solid elements, and the stress simulated by the elements proposed in the paper is approximate to the other simulating methods. So compared with calculations based on a mixture of shell and solid elements, the numerical simulation method given in the paper is more efficient and easier to do.
