新文化运动所要“猛勇”攻击的，是封建专制主义，并通过清除传统文化当中沉淀的渣滓，达到重建新文化之基础的目标。同时，新文化运动对于中国优秀的传统文化，并非持全盘否定的态度，而是在破除经学传统之时，强调以科学精神研究传统文化，将其思想纳入现代学科体系当中而使之重新焕发生机。

为观测新型肥料与常规肥料不同配施方案在辣椒生长和产量上的作用,选用菌肥(地康宝)、有机硅钙镁肥和土壤调理剂(蓝海半岛)3种新型肥料,设计了9个肥料配施方案进行试验研究。结果表明,随着有机肥增施和复合肥减施,产量呈先升后降的趋势,在T2[机肥2 000 kg·(667 m^(2))^(-1)+复合肥40 kg·(667 m^(2))^(-1)]时最高,较对照总施肥量提高30.77%,增产25.25%,但肥料利用率(PFP)较对照下降4.25%;新型肥料处理相较于对照均增加了地下部分干物质含量,其中T6[有机肥1 500 kg·(667 m^(2))^(-1)+复合肥60 kg·(667 m^(2))^(-1)+有机硅钙镁肥60 kg·(667 m^(2))^(-1)]有明显增产效果,产量和偏生产力(PFP)分别比对照高43.81%和38.61%,较T2总施肥量减少20.59%,增产14.82%,PFP提高44.76%;T5处理地康宝菌肥能提高PFP,但与对照差异不显著;通过不同的配施方案研究还发现所选3种新型肥料的肥效不够稳定,还需要后续完善改进。

We investigate the precise large deviations of random sums of negatively dependent random variables with consistently varying tails. We find out the asymptotic behavior of precise large deviations of random sums is insensitive to the negative dependence. We also consider the generalized dependent compound renewal risk model with consistent variation, which including premium process and claim process, and obtain the asymptotic behavior of the tail probabilities of the claim surplus process.

Erlotinib is an orally administered, highly effective, specific epidermal growth factor receptor tyrosine kinase inhibitor, used to treat non-small cell lung cancer and pancreatic cancer. The traditional synthetic methods for Erlotinib exhibit long reaction time and safety concern. Herein, we describe a novel five-step route for the synthesis of Erlotinib in flow. These five steps comprise etherification, nitration, reduction,addition and cyclization reactions. All steps were optimized and converted to continuous flow process,which drastically reduces the reaction time and considerably improves the process safety as well as the total yield. Enabled by five continuous flow units, Erlotinib is efficiently afforded with an E-factor of 38,an overall yield of 83%, and a total residence time of 25.1 min. Majority steps in this process have been optimized for quantitative conversion, which offers the possibility of telescoping the entire process.

Aluminum oxide(Al_(2)O_(3))ceramics have been widely utilized as circuit substrates owing to their exceptional performance.In this study,boron nitride microribbon(BNMR)/Al_(2)O_(3)composite ceramics are prepared using spark plasma sintering(SPS).This study examines the effect of varying the amount of toughened phase BNMR on the density,mechanical properties,dielectric constant,and thermal conductivity of BNMR/Al_(2)O_(3)composite ceramics while also exploring the mechanisms behind the toughening and increased thermal conductivity of the fabricated ceramics.The results showed that for a BNMR content of 5 wt%,BNMR/Al_(2)O_(3)composite ceramics displayed more enhanced characteristics than pure Al_(2)O_(3)ceramics.In particular,the relative density,hardness,fracture toughness,and bending strength were 99.95%±0.025%,34.11±1.5 GPa,5.42±0.21 MPa·m1/2,and 375±2.5 MPa,respectively.These values represent increases of 0.76%,70%,35%,and 25%,respectively,compared with the corresponding values for pure Al_(2)O_(3)ceramics.Furthermore,during the SPS process,BNMRs are subjected to high temperatures and pressures,resulting in the bending and deformation of the Al_(2)O_(3)matrix;this leads to the formation of special thermal pathways within it.The dielectric constant of the composite ceramics decreased by 25.6%,whereas the thermal conductivity increased by 45.6%compared with that of the pure Al_(2)O_(3)ceramics.The results of this study provide valuable insights into ways of enhancing the performance of Al_(2)O_(3)-based ceramic substrates by incorporating novel BNMRs as a second phase.These improvements are significant for potential applications in circuit substrates and related fields that require high-performance materials with improved mechanical properties and thermal conductivities.

A hyperbranched epoxy(AHEP)resin with terminal allyl groups was synthesized.The number average molecular weight of the synthesized AHEP is 1260,the multi-dispersion coefficient is 1.88,and the branching degree is 0.9.The hyperbranched epoxy resin and bismaleimide(BMI)monomer were heated to extend the chain and then blended and cured with methyl nadic anhydride.Studies have found that when the molar ratio of AHEP:BDM is 1:2,the mechanical properties and heat resistance of the resin casting body reach the best.Among them,the impact toughness was 15.05 kg/m^(2),the bending strength was 101 MPa,and the heat resistance temperature index was 229.23℃.We used AHEP to toughen bismaleimide resin in three ways simultaneously:hyperbranched structure,allyl copolymerized brackets chain and flexible side chain(epoxy group)addition.Experiments have proved that AHEP can improve the flexibility of the BMI chain and maintain its heat resistance,thereby forming a matrix with excellent mechanical properties and processing properties.

The pharmaceutical industry is now paying increased attention to continuous manufacturing.While the revolution to continuous and automated manufacturing is deepening in most of the top pharma companies in the world,the advancement of automated pharmaceutical continuous manufacturing in China is relatively slow due to some key challenges including the lack of knowledge on the related technologies and shortage of qualified personnels.In this review,emphasis is given to two of the crucial technologies in automated pharmaceutical continuous manufacturing,i.e.,process analytical technology(PAT)and self-optimizing algorithm.Research work published in recent 5 years employing advanced PAT tools and self-optimization algorithms is introduced,which represents the great progress that has been made in automated pharmaceutical continuous manufacturing.

A new bioreactor on the basis of a dynamic fluidized bed was designed, which combines advantages of the fluidized bed and a biological contactor. The experiments of start-up, nor- mal operation and parameter adjustment are carried out. The re- sults show that the bioreactor can be quickly started up in the condition that the fill is 50%, the hydraulic retention time is 72 min, aerate speed is 2.5 m3/h, rotation-cage rotated speed is 1.5 r/min, and the removal rates of chemical oxygen demand (CODCr) and Ammonia nitrogen (NH3-N) are 75.34% and 80.98% respec- tively. The influence of the operation parameter on removal rates of the bioreactor is analyzed, and an appropriate operation pa- rameter is provided.
