B2-CuZr phase reinforced amorphous alloy matrix composites has become one of the research hotspots in the field of materials science due to the“transformation-induced plasticity”phenomenon,which makes the composites show better macroscopic plastic deformability and obvious work-hardening behavior compared to the conventional amorphous alloy matrix composites reinforced with ductile ***,the in-situ metastable B2-CuZr phase tends to undergo eutectoid decomposition during solidification,and the volume fraction,size,and distribution of B2-CuZr phase are difficult to control,which limits the development and application of these *** date,much efforts have been made to solve the above problems through composition optimization,casting parameter tailoring,and post-processing *** this study,a review was given based on relevant studies,focusing on the predictive approach,reinforcing mechanism,and microstructure tailoring methods of B2-CuZr phase reinforced amorphous alloy matrix *** research focus and future prospects were also given for the future development of the present composite system.

作者：舒畅成程萱浙江省衢州市衢江区农业局浙江衢州324022

试验结果表明，百合施用钾肥增产效果能达到极显著水平。但是，钾肥施用过多，影响土壤养分平衡，从而抑制百合对其它养分的吸收，每公顷施K2O75～150kg为宜。钾肥施用方法以1／2作基肥，1／2作蕾肥为佳，既克服了因土壤含钾量低产生的... 详细信息

试验结果表明，百合施用钾肥增产效果能达到极显著水平。但是，钾肥施用过多，影响土壤养分平衡，从而抑制百合对其它养分的吸收，每公顷施K2O75～150kg为宜。钾肥施用方法以1／2作基肥，1／2作蕾肥为佳，既克服了因土壤含钾量低产生的后期供钾不足的缺点，又满足了百合中后期对钾的营养需求。因此，百合鳞茎的产量和净收益均最高。

Tumor recurrence, the Gordian knot of liver transplantation for malignancies, may be attributed to many parameters. The technique of the “classical” recipient hepatectomy is believed to be one of the potential reasons to cause tumor evasion because of the possible increase of circulating tumor cells, thus leading to an increased recurrent rate. On this background, the no-touch oncological recipient hepatectomy technique has been developed. A comprehensive review of the development and the key surgical steps of the no-touch recipient hepatectomy is presented. This technique might improve clinical outcomes, especially for those recipients who are at a high risk for tumor recurrence. Multicenter prospective studies should be set up to further validate the prognostic role of this technique in patients with liver cancer treated with liver transplantation.

Backward Monte Carlo method of the complicated and exact three-dimensional turbine with the spectral emission and reflection characteristics of the turbine blades materials and the spectral absorption and emission characteristics of combustion gas is *** factors affecting the accuracy of the radiation temperature measurement are *** results show that reducing the distance from the probe to the target surface can reduce the effect of the environment on the measurement *** the temperature and emissivity of the target surface can improve the measurement *** reflection characteristics of the surfaces have little influence on the radiation temperature measurement,so the blades can be considered as diffuse reflectors in order to improve the calculation *** temperature measurement accuracy decreases rapidly as the temperature of the combustion gas *** temperature measurement accuracy decreases with the increase of total gas pressure and H2O *** measuring the temperature of rotating blades,the apparent emissivity of the target surface is inversely proportional to the measurement accuracy.
