With Hemerocallis fulva‘Golden Doll'as an experimental material,the effects of different concentrations of neutral salt( NaCl) and alkaline salt( NaHCO3) stresses on photosynthesis and chlorophyll fluorescence characteristics in H. fulva seedlings were studied. The results showed that salt stress treatment significantly reduced the photosynthetic capacity of H. fulva. Under the NaCl and NaHCO3 stresses,the photosynthetic characteristics and chlorophyll fluorescence parameters of H. fulva seedlings were basically the same,but the photosynthetic characteristics and chlorophyll fluorescence parameter values of H. fulva seedlings were significantly different under different salt types and salt concentrations. With the extension of days of salt stress and the increase of salt concentration,the initial fluorescence yield( Fo) and non-photochemical quenching coefficient( NPQ) increased;the maximum fluorescence yield( Fm),maximum photochemical efficiency( Fv/Fm),PSII actual photosynthetic quantum yield( Y) and apparent quantum efficiency( AQY) all showed a downward trend;and moreover,with the extension of days of salt stress and the increase of salt concentration,the net photosynthetic rate( Pn) decreased and the intercellular CO2 concentration( Ci) increased. It was speculated that under salt stress,the photosynthetic characteristics of H. fulva leaves were inhibited. On the one hand,the non-stomatal limiting factor,i. e.,the chlorophyll content decreased,which led to the inhibition of photosynthetic characteristics. On the other hand,the decrease in the photosynthetic performance of mesophyll cells led to a decrease in the net photosynthetic rate of H. fulva. The changes of photosynthetic characteristics and chlorophyll fluorescence parameters in H. fulva caused by salt stress were closely related to the types of salts and salt concentration. High salt stress significantly inhibited the photosynthetic capacity of H. fulva‘Golden Doll',and the effect of NaHCO3 on H. fulva seedlings was significantly greater than that of NaCl. 展开更多

But the model of doll which can be obtained is static so the posture of the doll is single. On the other hand, the modification of the model is very difficult to non-professions. This paper proposes an rapid generation method of character doll with rotatable limbs, which is through adding the sphere joint to the doll's model automatically. After the model is segmented by drawing a line interactively, the sphere joint is created based on the segmentation boundary through entity modeling method. Lastly the two models of the doll and the joint are composited and printed. Some doll's model are tested on the FDM(Fused Deposition Modeling) 3D printer using this process. The results are more interesting and the efficiency has been greatly improved compared with modifying the model manually. 展开更多

However, the two heroines in these two plays, Nora Helmer and Lady Macbeth, demonstrate similar feminist qualities. By staging an overall contrastive analysis on the personality and tragic life of two protagonists from the perspective of feminism, it is founded that both of them are victims oppressed by the patriarchal system and they all have feminine consciousness against this system. Nevertheless, their distinctive complex personalities and different story settings make the reasons for their rebellion differ in many ways and they end up with different endings. 展开更多

As the play shares an open ending, many critics seem to try to find a way out for Nora. Nora is supposed as the first woman to pronounce the "Women Declaration of Independence". She has become the most courageous women for fighting an equal place in family. However, this paper focuses mainly on the comparison between Nora and Kristine the relatively less popular character. Kristine plays a role of girlhood friend of Nora as well as the one who solves the debt problem and brings a new problem into Nora's family. She serves a model for Nora. Ibsen writes Nora as she is, but it is Kristine who leads Nora onto the road of finding herself. Through the image of Kristine we can conclude that Nora might have all kinds road to tread before her but each one leads to a home-her true home. 展开更多
