The unification and innovation of cancer pathogenesis is the key to the breakthrough of Chinese medicine. According to the related theory in Neijing, cancer in different parts of the body could be classified based on the five elements. Chinese mainland is divided into five parts： east, south, west, north and central section. Based on the annual data of China Cancer Center, we analyzed the data of 72 cancer registries covering 32 provinces and autonomous regions for consecutive 5 years. The results showed that the total incidence of the five regions in the mainland of China was statistically significant （F = 8.561, P 〈 0.01）; the east was the highest, the west was the lowest, and the south, middle and north were in the middle level. The incidence of tumors in different parts of the human body was statistically significant （F = 523.382, P 〈 0.01）. The incidence rate from high to low was lung, spleen, kidney, liver and heart. The heat is too much in China＇s eastern and the southern, and Qi is not too enough in the northwest. Five-Qi was imbalance. The pathogenesis of cancer is due to the two aspects, deficiency of five Zang-organs and abnormal seasonal climates. The viscera weakness for a long period and abnormal seasonal climates causes the body Yin and Yang disharmony, resulting in five zang organs dysfunction.展开更多
Effects of micro-alloying elements and production process on microstructure, mechanical properties and precipitates of 600 MPa grade rebars were studied by using pilot test, metallographic observa- tion, tensile test,...Effects of micro-alloying elements and production process on microstructure, mechanical properties and precipitates of 600 MPa grade rebars were studied by using pilot test, metallographic observa- tion, tensile test, thermodynamic calculation and transmission electron microscopy. The results show that the tested steels are composed of ferrite and pearlite, in which the conterlt range of pearlite is 33%-45%. For vanadium micro-alloyed steel, interphase preeipitation Strengthening effect of V can be promoted and the yield strength of tested steels can be increased with increasing V content and de- creasing finishing rolling temperature. The temperature of terminated cooling should be more than 700 ℃ when the water cooling is used. When niobium is added to the steel, more coarse （Nb,V）C,N precipitates are generated at high temperature, so that the solid solubility of precipitated phases of vanadium is reduced and the precipitation strengthening effect of vanadium is weakened.展开更多
The 3-morpholin-4-yl-propyl-ammine tetrafluoroborate（MPA^＋）（BF4^-）（1） and the 3-morpholin-4-ylpropyl-ammine perchlorate（MPA^＋）（ClO4^-）（2） were synthesized and separated as colorless block crystal.The（M...The 3-morpholin-4-yl-propyl-ammine tetrafluoroborate（MPA^＋）（BF4^-）（1） and the 3-morpholin-4-ylpropyl-ammine perchlorate（MPA^＋）（ClO4^-）（2） were synthesized and separated as colorless block crystal.The（MPA^＋）（BF4^-） undergoes a reversible phase transition at ca.347.3 K with a hysteresis of16.1 K.Dielectric measurement also can confirm the transition.The crystal structure determined at300 K（monoclinic,P21/c,a = 9.978（2）A,b = 7.5206（15）A,c = 15.058（3）A,b = 96.99（3）8,v = 1121.6（4）A^3,z = 4） and 373 K（triclinic,P-1,a = 10.021（7）A,b = 7.662（3）A,c = 7.920（4）A,a = 95.012（14）8,b = 101.67（4）8,g = 91.48（3）8,v = 592.7（6）A^3,z = 2） reveal that this compound has two phase.The most distinct is the BF4^- anion is disorder at 373 K,which is probably the driving force of the phase transition.DSC measurement,dielectric measurement and the crystal structure of the compound 2 did not change at 300 K and 100 K.展开更多
