The results show that: the fillers of SiO_2 based investment consist of SiO_2,Al_2O_3 and MgO,and the binder is NH_4H_2PO_4;for SiO_2 based investment,the bulk density and the compression strength decrease,the apparent porosity and the thermal expansion increase,when the specimens are heated to 900 ℃;the fil.

结果表明：氧化硅系包埋料的骨料是氧化硅、氧化铝、氧化镁，结合剂为磷酸二氢铵，其900℃煅烧后显气孔率增加，体积密度下降，耐压强度降低，热膨胀增大；氧化铝系包埋料的骨料是氧化铝和氧化镁，结合剂为磷酸二氢铵，其900℃烧后显气孔率增加，体积密度下降，热膨胀变化不大；氧化镁系包埋料的骨料是氧化镁和氧化铝，结合剂是铝酸钙水泥，其900℃烧后耐压强度明显降低，热膨胀明显增大。

This is based on a system of logic that has subsequently been adopted by most of the other Indian schools, much in the same way that Western science and philosophy can be said to be largely based on Aristotelian logic.

这是基于一个逻辑体系，随后被大多数其他印度学派所采用，可以说很大程度上就像西方科学和哲学是以亚里士多德的逻辑为基础一样。

We have accomplished under mentioned arithmetic in the project, which are the wavelet zero tree coding arithmetic based on difference signal and the non compression arithmetic based on the integer wavelet transform of interested area. We have achieved the huge amount of data processing and storing in real time、high speed and multi-channel.

Based on the analysis results and the principle that the concentration of the contaminants in a mine varies in a constant ratio and the degree of their hazard varies in an arithmetic progression,the evaluating indicators were determined for the air quality in a uranium mine,and an evaluation model was proposed for the evaluation of the air quality in a uranium mine based on integrated scale index on ...

该模型克服了传统评价方法主要从辐射危害的角度进行评价的局限，能综合评价铀矿山井下空气的质量。采用该模型对某铀矿井4个用风点的空气质量进行了评价，获得了4个用风点空气质量综合评价等级和应采取的相应的对策。评价结果能为铀矿井通风系统的设计和空气质量的安全评价提供参考。
