optimal proportion
2.(4) InCrW_(11)/PVP hybrid material. The optimal proportion of the component compounds and the pH of the synthesis reaction are given. The products were characterized by means of IR and XRD.
3.The NIE and the AIE selected are mixed in various proportions and,by using the concept of additivity for HLB values of surfactant mixtures,the optimal proportion of the NIE an the AIE is determined from O/W emulsion viscosity vz HLB value relationships.
4.Results Among the selected dosages, the theoritical optimal proportion of levant storax oil and dalbergiae odoriferae oil, which were both in the Shuangxiangyou soft capsules, was 1:5:1.0; the pharmacodynamics experiment indicated that the Shuangxiangyou had the significant anti-myocardial ischemia effect compared with model control group.
5.The research results for the stability of juice of red Chinese date with fruit showed that the optimal proportion of red Chinese date mud to subsidiary material mud was 7∶3. In the use of stablizer,the LM pectin(0.1%) with CaCl 2(0.2%),or CMC Na(0.2 %),or CMC Na(0.1 %)and agar(0.1 %)had better effect on stabilization.
6.1.2 The different concentration of neurotransmitters of the rats between model group and normal group had been show that PCPA can reduced the content of 5-HT DA> E> NE, ACTH. However, Jiaotai Pill can enhanced the concentration of neurotransmitters, and improved the sleeping quality of rats. 2. The research for optimal proportion of the two herbs in Jiaotai Pill.
7.(2) three heteropoly acids in such a general formula as H_nM(H_2O)XW_(11)O_(39) i.e. H_7[In(H_2O)CoW_(11)O_(39)]·14H_2O, H_6[In(H_2O)CrW_(11)O_(39)]·11H_2O and H_4[Ti(H_2O)TiW_(11)O_(39)]·7H_2O were synthesized by the stepwise acidification and the stepwise addition of solutions of the component elements as well as ion exchanging method. The optimal proportion of the component compounds and the pH of the synthesis reaction are given.
8.Methods The optimal proportion of levant storax oil and dalbergiae odoriferae oil, which were active ingredients of the traditional Chinese medicine styrax and dalbergiae odoriferae, was bolted by using uniform-design method; the myocardial ischemia model of rats was set up through the induction of isoprel and the above rats were divided into 5 groups, which were model control group, high dose group of Shuangxiangyou, middle dose group of Shuangxiangyou, low dose group of Shuangxiangyou, and positive control group of Muskone.
9.The influence of retarder on the seaing time and ultimate strength of gypsum plaster was investigated in this paper.The experimental results indicate that the effect of single retarder,such as citric acid,is inferior to that of composite retarder which Was made of blending citric acid with a few Portland cement(about 0.5?,by weight).The effect of different water-retention agents,such as Polyvinyl alcohol(PVA),carboxymethyl cellulose (CMC),and Na-bentonite,etc.,Was also studied,and the results demonstrate that by means of adding organic and inorganic water-retention agent simultaneously the water-retention of plastering slurry can obviously be improved.The optimal mix proportion of gypsum plaster suitable to finish coat of walls and ceilings of buildings has been got by use of factorial experiment with orthogonal array accounting for interactions between factors each other.
10.In this paper, based on the optimal selection of the mix proportion,a kind of high-perfor mance PFA concrete, with a little dosage of cement (C≤165kg/m3), the PFA content being above 70%,HPC with high workability (slump: 24 cm)whose strength is above 80 MPa,has been obtained.
