针对毛衫产品族设计中的模块划分规则不清晰、可操作性不强等问题,提出一种模块化的毛衫产品族设计方法。根据毛衫结构的特点,设计了模块划分规则:突出变型设计的方便性和产品族设计的通用性;将基于区域结构的横向模块、纵向模块与独立于区域结构的全身结构、装饰结构有效结合在一起,构成毛衫产品族的基本设计单元。另外,设计了一套模块化产品族设计的评价体系,根据多样性、通用性和新颖性3个指标计算出平均设计时间成本,并给出了评价指标与时间成本的关系、时间成本与企业收益之间的关系。验证结果表明,所设计模块化方法在不降低产品族通用性的同时,可提高产品族的新颖性,进一步提升产品族的多样性,从而降低设计时间与成本。

The four isomers of 6,7-dihydroxy-3,7-dimethyloct-2-enoic acid 2 were synthesized via the selective direct Sharpless asymmetry dihydroxylation of geraniol as the key step in 35.0%-48.0% overall yields with91.9%-97.7% ee values for esters 4 and 31,3%-36.4% overall yields with 90.3-97.5% ee values for acids 2 using cis-and trans-geraniol as raw materials. Their structures were characterized by;H,;C NMR and HR-eSI-MS data. The in vivo bioassay results showed that the chiral acid（Z, S）-2 was a good lead compound with 80%-100% inhibitory rates against P. cubensis, e. graminis, P. sorghi and C. gloeosporioides at the concentration of 400 μg/mL.

A liquid-solid fluidized bed separator, used for the separation of coarse slime, was developed. Test parti- cles sized in the range from 0.25 to 0.5, 0.5 to 1.0, and 0.25 to 1.0 mm were separated in the liquid-solid fluidized bed. Beds with column heights of 1200, 1500, and 1800 mm were tried. The clean coal and the railings were subsequently analyzed by float-sink testing. The results showed that the ash and yield of clean coal both decreased with increasing column height, for all three size fractions, and that the ash of the clean coal obtained from tests on the broader size fraction was less than that from the narrower sized fractions. The separation density decreased with increasing column height. The lowest e value was seen for a column height of 1500 ram, for which conditions the separation density was 1.45 g/cm3. The e value was 0.084 for the 0.25-0.5 mm fraction but the corresponding separation density was 1.48 g/cm3, and the e value 0.089, for the broader 0.25-1.0 mm fraction.

Herein, two efficient palladium-catalyzed intermolecular oxidative coupling reactions of （Z）-enamines with isocyanides via selective β-C（sp2）-H and/or C=C bond cleavage have been developed, leading to controllable chemodivergent and stereoselective construction of a wide range of （e）-β-carbamoylenamine derivatives containing strong intramolecular hydrogen bonds. Furthermore, possible reaction pathways for these transfor- mations are proposed on the basis of preliminary mechanism studies.

Ultrafine nano-scale Cu2Sb alloy confined in a three-dimensional porous carbon was synthesized using NaCl template-assisted vacuum freeze-drying followed by high-temperature sintering and was evaluated as an anode for sodium-ion batteries(SIBs)and potassium-ion batteries(PIBs).The alloy exerts excellent cycling durability(the capacity can be maintained at 328.3 mA·h·g^(-1) after 100 cycles for SIBs and 260 mA·h·g^(-1) for PIBs)and rate capability(199 mA·h·g^(-1) at 5 A·g^(-1) for SIBs and 148 mA·h·g^(-1) at 5 A·g^(-1) for PIBs)because of the smooth electron transport path,fast Na/K ion diffusion rate,and restricted volume changes from the synergistic effect of three-dimensional porous carbon networks and the ultrafine bimetallic *** study provides an ingenious design route and a simple preparation method toward exploring a high-property electrode for K-ion and Na-ion batteries,and it also introduces broad application prospects for other electrochemical applications.
