I have summarized some English learning principles and hope

the results can be summarized as follows.其结果可以归纳如下：in japan,demographics are defined by a sustained decline in birth rates and an increase in longevity,leading to an aging of the population.the sharp decline in fertility rates is also responsible for a significant decline of japan's population.在日本,人口统计数据可定义为出生率的持续下降和寿命的增长,从而导致人口的老化.生育率的急剧下降也是日本人口明显下降的起因.as a result of a contracting workforce,the level of real GDP is projected to fall (from a baseline with a constant workforce)by about 20 percent cumulatively over the next half-century or so.由于合同劳动力的结果,实际GDP的水平在今后半个世纪左右预计会（从一个恒定劳动力的基准）下降约20％.in terms of growth,annual GDP growth in japan may be lower by about 0.5 percent for some time as the economy settles to a long-run equilibrium with a permanently higher elderly dependency ratio and smaller supply of labor.就增长来说,日本GDP的年增长会在相当长的时间内低于约0.5％,因为其经济稳定在一个长期的平衡状态,同时伴随着永久性较高的老年从属比率和较少的劳动力供应.
in per capita terms,GDP per person declines slightly in the long run (relative to baseline.）output falls in proportion to the contraction of labor-measured in efficiency units.从每人的意义上说,人均GDP在长期中（相对于基准）将稍有下降,产量将按以效率单位衡量的劳动力收缩成比例下降.however,the percent decline in effective labor supply is larger than the fall in the (adult)population,as the share of elderly increases.investment and saving levels also decline with GDP through the adjustment process.不过,因为老年人所占份额的关系,有效劳动力供应的下降百分比要大于（成年）人口下降的百分比.投资和储蓄水平也将通过这一调节过程而随GDP的下降而下降.the decline in investment reflects the desire to shed capital in the wake of the contraction in labor and output,though investment rates(as a share of GDP)remain unchanged.投资的下降反映了由于劳动力和产量的收缩而流出资金的愿望,尽管投资比率（作为GDP的一部分）仍保持不变.however,saving rates and,hence,the current account ratio increase slightly as the population ages.不过,储蓄率,因而活期账户比率会随人口年龄的增大而稍有增加.despite a higher proportion of elderly (who tend to save less),the increase in longevity and the decline in the inflow of young agents(who tend to have high consumption propensities)act to raise saving rates in japan.尽管有较高的（倾向于较少储蓄的）老年人比例,但寿命的延长和年轻经纪人（他们往往有高消费的喜好）进入的减少对提升日本的储蓄率是有作用的.
in terms of policy implications,the analysis highlights the importance of taking into account prospective changes in the macroeconomic environment when evaluating policies that address the challenges posed by population aging.从政策的关系来看,分析突出了在评价应对人口老化带来的挑战的政策时,考虑宏观经济环境未来变化的重要性an assessment of fiscal sustainability,for example,that focused only on the social security dimensions would miss an important component of the analysis if it ignored the macroeconomic implications of demographic changes for the fiscal accounts.例如,一份关于仅着眼于社会安全方面的财政可持续性的评估,如果忽略了财政帐目人口统计变化的宏观经济关系,那么就会遗漏该分析中一个重要的成分.similarly,the endogenous response in private behavior to various policy changes should also be taken into account when examining policy reforms.同样,在探讨政策改革时,对各种政策私人行为的内源性反应也应加以考虑.on this last point,the simulation analysis suggests that changes in social security benefits can have a notable impact on private sector saving.在这最后一点上,模拟分析表明,社会安全效益的变化对私人方面的存款会有显著的影响.in particular,a balanced decline in benefit and contribution rates is shown to boost private saving rates by nearly half of the reduction in benefit rates,as agents anticipate having to self-finance more of their consumption in retirement.特别是在利润和贡献率方面的平衡下降被证明能提升私人的储蓄率,幅度接近于利润率下降幅度的一半,因为经纪人预期,人们将不得不在自己的退休消费中自筹更多的资金.

结果归纳在这里扩展和放置在一个较大的角度,在[ 2 ] .

会议记录是一种将会上所发生的事做总结或浓缩的记录方式.

nelson7收集和总结了能量释放率数据为各种商品及材料,生长速率和峰值能量释放率的粗糙的迹象.他的数据概况表3.6.

工装夹具的优势可以总结如下:
1.不用采用划线和其他测量及制定方法.
2.非熟练工人也可以从容、快捷的实现工件准确定位,用工具指导或设置.
3.组装的零件是起到促进作用的 ,因为所有组件将在小范围内受到限制. 相同“尝试”和归档工作将被取消.
4.一些部分是可互换的, 如果此产品在大范围内进行销售 ,零件问题也就容易解决了.

希望可以帮助到你!
