However,the density of WSi2-MoSi2 system alloy materials is larger,it is difficult to meet the requirements of the structure materials of modern aerospace used.
Experimental procedure The raw material were molybdenum powder, silicon powder, aluminum powder and chromium powder(purity>99.5%) in this experiment.MoSi2-AlCr2 quasibinary system alloys were prepared which the molecular content of AlCr2 were 0%,10%,20%,30%,40%,60%,80% and 100% separately.Raw material ratio of alloy powders is shown in Table 1.The raw material powders of alloys No.1 to No.4 were mechanical activation 6 h in QM-1SP type planetary ball mill,the proportion of balls and materials was ten to one,the speed was 150 times per minute.The raw material powders of alloys No.5 to No.8 were mixed 0.5 h in QM-3SP type planetary ball mill, the proportion of balls and materials was five to one,the speed was 100 times per minute.The raw material powders of mixed were hot pressed sintering in ZT-63-20Y vacuum hot-pressing furnace,the sintering temperature was1400℃,the holding time was 1 hour, the sintering pressure was 20 MP.

Liuweidihuang pill comprises of six Chinese herbal materials which are Ripe rehmannia glutinosa, Tuckahoe, Alisma, Paeonia suffruticosa, dogberry and yam.
Chemical analysis indicates that the Materials of Liuweidihuang contain many active ingredients such as polysaccharides, glucoside, terpenoids.
As traditional Liuweidihuang pill is made by simple breaking of six Chinese herbal materials, the dosage is too much and the bioavailability is low.

Introduction With the development of science and technology of concrete, construction has higher and higher demand for performance of concrete.
Because of low SO3 content in chemical composition of mineral fillers, fly ash and other admixtures, these admixtures which added into concrete to instead part cement can reduce CaSO4 content of cementitious materials in concrete, this can affect the performance of concrete.
Due to admixed different content of desulphurization gypsum into concrete cause the SO3 change in concrete, we should calculate the SO3 total content in cementitious material according to the proportion of the number of raw materials used.
In addition, due to the litter water need for desulphurization gypsum and more than 70% particle size of fly ash and desulphurization gypsum distribution in 0 ~ 10μm 20 ~ 60μm, when admixed desulphurization gypsum replace some fly ash, it can change the particle gradation of the original cementitious materials, the slump increase and the strength also increase.

It is significant to admit that stiff materials like residual soils have discontinuities which the small scale tests may sometimes unable to detect, and over-estimate soil shear strength.
Conclusion Through conducting surveys and concerning materials, it is apparent that the causes of slope failures are related to poor and/or flawed design and construction and non-preferential maintenance criteria.
