计算误差

And the cost of dealing with exponentially increasing numbers of error-tainted possibilities just isn't worth the immense trouble, even if computation is free.

因为随着你所预测的时间点离现在越远，你所要去处理的可能性（而且还是被误差所污染了的可能性），其数量会呈指数增长的趋势，在这种情况下，即使计算本身是免费的，你所要花费的成本也会让你根本就不值得去费这么大劲、接手这么大的麻烦。

"The lack of additional autoinjector doses is a serious concern," the authors write."Nevertheless, pediatricians are advised to prescribe the optimal dose from an autoinjector for each child, even when that dose cannot possibly be precisely 0.01 mg/kg.... For children who weigh less than 10 kg (22 lb), the physician and family should weigh the risks of delay in dosing and dosing errors when an ampule/syringe/needle is used against accepting nonideal autoinjector doses, taking into consideration the specific health needs of the individual child and abilities of the caregivers."

&附加剂量的缺乏受到密切关注，&作者写道，&不过，即使不能按0.01 mg/kg精确计算剂量时，仍建议儿科医师为每个儿童开出自动注射剂最优剂量。。。，对于体重轻于10kg(22lb)的儿童，考虑到儿童个体特殊健康需求及家庭护理人员的能力，当使用的安瓿、针头、注射器与接受非理想自动注射剂量不配套时，医师和家长应当权衡剂量延误及剂量误差风险。&
