The main objective of this article is to study both dynamic and structural transitions of the Taylor-Couette flow, by using the dynamic transition theory and geometric theory of incompressible flows developed recently by the authors. In particular, it is shown that as the Taylor number crosses the critical number, the system undergoes either a continuous or a jump dynamic transition, dictated by the sign of a computable, nondimensional parameter R. In addition, it is also shown that the new transition states have the Taylor vortex type of flow structure, which is structurally stable.

Nanocrystalline diamond films were deposited on polished Si wafer surface with electron assisted hot filament chemical vapor deposition at 1 kPa gas pressure, the deposited films were characterized and observed by Raman spectrum, X-ray diffraction, atomic force microscopy and semiconductor characterization system. The results show that when 8 A bias current is applied for 5 h, the surface roughness decreases to 28.5 nm. After 6 and 8 A bias current are applied for 1 h, and the nanocrystalline films deposition continue for 4 h with 0 A bias current at 1 kPa gas pressure. The nanocrystalline diamond films with 0.5×109 and 1×1010 Ω·cm resistivity respectively are obtained. It is demonstrated that electron bombardment plays an important role of nucleation to deposit diamond films with smooth surface and high resistivity.

With electron assisted hot filament chemical vapor deposition technology, nanocrystalline diamond films were deposited on polished n-(100)Si wafer surface. The deposited films were characterized and observed by Raman spectrum, X-ray diffraction, semiconductor characterization system and Hall effective measurement system. The results show that with EA-HFCVD, not only an undoped nanocrystalline diamond films with high-conductivity (p-type semiconducting) but also a p-n heterojunction diode between the nanocrystalline diamond films and n-Si substrate is fabricated successfully. The p-n heterojunction has smaller forward resistance and bigger positive resistance. The p-n junction effective is evident.

Access to embryonic developmental stages is essential basic work for understanding how organisms develop. In this study, seven egg clutches（range 209–564 eggs） of ornamented pygmy frog Microhyla fissipes（Amphibia, Anura, Microhylidae） were obtained from seven breeding pairs in laboratory. One egg clutch of them was observed for the embryonic development, and the staging table of normal development was constructed based on morphological and physiological characteristics. Forty-five developmental stages were defined for M. fissipes, and two major developmental periods were designated： 1） early embryonic development period（stages 1–28）, from fertilization to operculum completion stage, lasted for 82.6 hours at water temperature（WT） 23–25℃; 2） larval development period（stages 29–45）, from operculum completion to tail complete absorption stage, took 38 days at WT 22–26.5℃, showing that the embryos of this species develop rapidly. In addition, the tadpoles were transparent, which is similar to those in field. These characteristics suggest that M. fissipes would be a good model to study developmental biology, adaptive mechanisms from aquatic to terrestrial phases, environmental toxicology, and human disease.

Objective:To explore the potential effect of melatonin on the in-vitro maturation of mouse oocytes under heat shock ***:This study used a heat shock model of mouse oocyte *** oocytes were randomly divided into three groups:control group,heat shock group and heat shock+melatonin group,in order to evaluate the effect of 1×10^(−9) mol/L melatonin on the quality of oocytes after heat ***:In comparison with the control group,the maturation rate of mouse oocytes in heat shock group was significantly decreased[(33.00±0.07)%vs.(85.00±0.03)%,p<0.01],with abnormal spindle assembly,and the early apoptosis rate was significantly increased[(59.7±4.5)%vs.(22.0±3.5)%,p<0.01].Compared with heat shock group,the maturation rate of oocytes was significantly increased in heat shock+melatonin group[(70.00±0.05)%vs.(33.00±0.07)%,p<0.01],meanwhile,the spindle abnormality rate and the early apoptosis rate were significantly decreased accordingly[(37.3±6.1)%vs.(59.7±4.5)%,p<0.01].The expression level of heat shock protein 70 was significantly up-regulated in heat shock+melatonin group in comparison with other two groups(p<0.01).Conclusions:By regulating the over-expression of heat shock protein 70,melatonin can improve the declined maturation rate of oocytes and the increased rates of spindle assembly abnormality and early apoptosis caused by heat shock.
