增田涉改译本《故乡》考释——兼论鲁迅对井上红梅译《鲁迅全集》之批判

增田涉改译本《故乡》是在《大调和》译本、佐藤译本、井上译本的基础之上改译而成,译文质量很高,对《故乡》在日本的经典化产生了很大影响。井上红梅译本《故乡》参照了佐藤译本及《大调和》译本,有许多值得借鉴的译法,并非鲁迅所说的未参照佐藤译文。增田改译本在对《大调和》译本、井上译本的参照过程中尽量参照《大调和》译本的译法,甚至直接照搬,参照井上译本虽然尽量有所改动,但还是能看到有些语句是从井上译本改动而来,可见增田涉对井上译本的认可以及在改译过程中碍于鲁迅对井上红梅的评价而避免直接采用井上译法的复杂心态。

Adjustment on gibbsite and boehmite co-precipitation from supersaturated sodium aluminate solutions

Gibbsite is the usual precipitation product from alumina refineries with either Bayer or sintering process.However,the advantage of boehmite precipitation over gibbsite precipitation is the significant energy saving in the subsequent calcination step.The current investigation takes a pragmatic approach to measure precipitation ratios,determine product phase,morphology and particle size distribution,and assess the impacts and adjustment capability of main parameters such as seed,temperature,ethanol medium,and supersaturation on the precipitation kinetics and alumina hydrate type during co-precipitation process.The results clarify that gibbsite and boehmite both can be precipitated from supersaturated sodium aluminate solutions simultaneously,and the competitive formation between Al(OH)3 and γ-AlOOH determines the main precipitate phases from pregnant liquor.Boehmite seeds,high temperature and ethanol addition can promote the boehmite precipitation and improve the mass fraction of boehmite in products.Co-precipitation changes the multimodal distribution of seeds to a normal and well distribution of products,and the particle size is more than several times that of seeds.

Resultant linear acceleration of an instrumented head form does not differ between junior and collegiate taekwondo athletes' kicks

Objective： The purpose of this study was to compare the effects of various taekwondo kicks and age （school level） in absolute terms and relative body mass on the resultant linear acceleration （RLA） of an instrumented head form. Methods： Forty-eight male （middle school： 16; high school： 16; university： 16） taekwondo athletes were recruited for this study. Subjects performed 10 turning, 10 jump spinning hook, and 10 jump back kicks on a Hybrid II head mounted on a height-adjustable frame. Results： A 2-way （School x Kick） MANOVA was used to determine the differences in RLA between schools （age groups） by type of kick. There was no univariate School main effect for absolute RLA （η2 = 0.06） and RLA relative to body mass （η2 = 0.06）. No univariate Kick main effects were found for absolute （η2 = 0.06） and relative RLA （η2 = 0.06）. Conclusion： It is of concern that RLA did not significantly differ between school levels, implying that young taekwondo athletes generate similar forces to their adult counterparts, possibly exposing young athletes to an increased risk for head ir^iuries.

Conclusions on the Implementation of Regulation of the National Significant Seismic Monitoring and Protection Regions from 1996 to 2012 in the Chinese Mainland

The regulation of the National Significant Seismic Monitoring and Protection Regions(NSSMPR for short) is defined by the Law of the Peoples Republic of China on Protecting Against and Mitigating Earthquake Disasters.The first stage of implementation of the regulation of NSSMPR in the Chinese mainland was finished from 1996 to 2005.The second stage is being carried on from 2006 to 2020.With the support of the National Social Science Foundation,this paper follows up and evaluates the implementation of the regulation of NSSMPR from 1996 to 2012 in the Chinese mainland.Based on analysis of earthquake examples and investigation data,we find that the effect of disaster mitigation is good,and on this basis,some suggestions are proposed to improve the regulation of NSSMPR.

A Note on the Maximal Functions on Weighted Harmonic AN Groups

In this paper, the authors point out that the methods used by Li(2004, 2005,2007) can be applied to study maximal functions on weighted harmonic AN groups.
