明胶的物理性能及照相性能依赖于明胶的分子量分布,因此,控制明胶分子的分子量分布很重要。我们研究了一种新的方法来控制明胶的分子量分布及物理性能。将明胶溶液用泵加压,然后从喷嘴高速喷射到一个碰撞盘,或者让喷射液相互碰撞。高分子量级分如h1和h2级分减少,γ和β级分增加或者减少,而样品中α级分增加;低分子量级分稍稍有所增加;样品黏度下降,但凝胶强度变化几乎不变。研究发现,水喷射法不仅在控制明胶分子量分布方面十分有效,且能有效地控制明胶的物理性能。

Spontaneous transition of the plasma confinement mode was observed in thehelical-axis heliotron device 'heliotron J' for three different plasma heating schemes, ***-only, NBI-only and the combination of ECh and NBI. the transition seems to occur above a certaincritical density. In addition to the confinement transition, a spontaneous shift of the hittingposition of the divertor plasma flux on the wall was observed. this shift could be related with thechange of the edge field topology caused by non-inductive toroidal currents.

In this paper, the coupled thermo-mechanical （tM） processes in the AEspoe Pillar Stability Experiment （APSE） carried out by the Swedish Nuclear Fuel and Waste Management Company （SKB） were simulated using both continuum and discontinuum based numerical methods. two-dimensional （2D） and three- dimensional （3D） finite element method （FEM） and 2D distinct element method （DEM） with particles were used. the main objective for the large scale in situ experiment is to investigate the yielding strength of crystalline rock and the formation of the excavation disturbed/damaged zone （EDZ） during excavation of two boreholes, pressurizing of one of the boreholes and heating. For the DEM simulations, the heat flow algorithm was newly introduced into the original code. the calculated stress, displacement and temperature distributions were compared with the ones obtained from in situ measurements and FEM simulations. A parametric study for initial microcracks was also performed to reproduce the spalling phenomena observed in the APSE.

A fast video camera is verified to be a powerful t0ol for observation of filaments/blobs near the last closed flux surface （LCFS）. In order to extract the fluctuation component from the raw data of the fast camera, a pre-processing technique, sliding time window averaging subtraction （StWAS） has been developed to remove the background of slowly varying emission from the bulk plasma. By using this pre-processing technique, the fast camera data are analyzed. A method to identify the filaments in the pre-processed image is also discussed.
