埋地管道新型预应力抗滑桩的应用

介绍了埋地输油管道新型预应务抗滑桩的构成和抗滑原理，并对其受力状况进行了分析。以某油加库外滑坡地段埋地输油管道的实际应用为例，表明采用新型预应力锚索抗滑桩保护滑坡地段的埋地输油管道不仅是可行的，而且具有较好的经济性、实用性和可靠性。     

复方增茸剂对梅花鹿茸产量与品质的影响

选择体质、体型、健康状况、产量性能相接近的梅花鹿50头，随机分为2组即试验组与对照组，将复方增茸剂混全饲料中投喂，每日1次，连续饲喂70d，观察该药对试验动物的影响。结果表明：应用复方增茸剂后，试验组鹿的血液中红细胞、血红蛋白、碱性磷酸酶、血钙和血磷量明显高于对照组，并且鹿茸中各种氨基酸的含量也明显高于对照组。该药具有促进造血机能，加快麂茸生长，提高鹿茸品质的作用。     

辽东地区落叶松人工林连作对立地质量的影响

采用解析木导向曲线法编制了辽东地区日本落叶松地位指数表。在此基础上，对落叶松地拉指数与立地因子及落叶松栽植代数的关系进行了分析，认为不同栽植代数对落叶松人工森地位指数影响差异显，落叶松连作造成立地质量下降。     

罐顶对罐壁应力的影响

在大型油罐设计中采用线性理论的方法,分析论述了罐顶对罐壁是否产生影响这一问题。通过对拱顶油罐、浮顶油罐的罐壁边界条件、罐顶边界条件的分析计算,求出各层壁板挠度方程中的待定系数,便可得出其应力。从线性方程中,可看出影响罐壁应力的主要因素是挠度方程中的待定系数。待定系数除受储罐尺寸、液位高度的影响外,还受罐顶重量、罐顶剪力和弯矩的影响。以10万m~3浮顶油罐和拱顶油罐为例,进一步证明,液位是罐壁应力的控制因素,而罐顶重量、罐顶剪力和弯矩对罐壁应力的影响可以忽略不计。     

兴安落叶松育苗容器质地及规格的研究

1988～1990年通过一年生苗的高生长、地径与合理密度的观察。兴安落叶松育苗容器材料和规格的研究结果表明,纸容器的苗木无论在苗高、地径上与其它容器比较都具有显著性差异,容器规格选择φ3.8×12.5cm为宜,较理想密度为910株/m~2。     

辛夷油的药理学研究

向大白鼠胸腔注入角叉菜胶诱发胸膜炎,8h后处死动物，测定其胸腔渗出液中白细胞数、蛋白质及前列腺素E2（PGE2）的含量，体内白细胞介素1（IL-1）和肿瘤坏死因子（TNF）的含量。结果显示，事先灌服辛夷油的试验组动物，其胸腔渗出液中白细胞数、蛋白质和PGE2的含量均显著小于模型对照组；IL-1和TNF的含量也明显小于模型组，说明辛夷油能抑制炎症介质的产生，具有抗炎效应。

Landscape and habitat factors affecting cabot's tragopan Tragopan caboti occurrence in habitat fragments.

Cabot's tragopan Tragopan caboti is an endemic and endangered pheasant of the lower montane forests of southeastern China. The typical habitats of the tragopan have been seriously fragmented because of forest management for timber production and farmland reclamation in recent years. The effects of the fragment size and isolation on the distribution of the cabot's tragopan were studied in Wuyanling Natural Reserve. Thirty one habitat fragments (2.5-48.5 ha) surrounded by non-habitat sapling coniferous forests, in an intensively managed forested landscape, were surveyed over four seasons for the occurrence of cabot's tragopan. Five of the 31 fragments were occupied in all four seasons and nine were not occupied. Both landscape and habitat factors affected the occurrence of cabot's tragopan, with landscape factors having the greatest effect. Large and less isolated habitat fragments containing a larger amount of the tree Daphniphyllum macropodum were occupied significantly more often than small, isolated fragments. The appearance of cabot's tragopan in the habitat fragments was best explained by the size of the fragments, the distance to the nearest suitable habitat and the amount of macropdous daphniphyllum trees. Our results could be used to improve the management of the forests where Cabot's tragopan occurs in southeastern China.
