| 1. | The net result of those conflicting trends is to cause optimum family size to be greater for low than for high heritability .
这些矛盾引起的实际结果是遗传力低的比遗传力高的要求比较大的最适家系。 |
| 2. | Annual household income by family size
依家庭人数计算家庭年所得 |
| 3. | Family size grouping
家庭人数组别 |
| 4. | Statistics show that the average family size increases in inverse ratio to the mother ' s years of education
统计数字表明，按平均数计算，母亲受教育年限越长，他的家庭人口就越少。 |
| 5. | All right ! i ' ve got cheese crakers , bubbling soft drinks and double chocolate icecreams - - - family size ! kind of . . . too much
好，我买来了奶酪膨化食品，冒泡的软饮料盒双重巧克力冰淇淋- -家庭装。是不是. . . .太多了？ |
| 6. | A three - decade - old policy limiting most couples to one child has made abortion a widely used method for controlling family size
计划生育条例已实行30年了，它限制大多数夫妇只能生育一个孩子，是控制人口膨胀的有力武器。 |
| 7. | There are many family factors such as family size , generation , family ' s monthly income , family ' s average " educational level , family ' s average age which exert influences on the behaviors of reading city - newspaper
对家庭成员读报行为产生影响的家庭因素有：家庭规模、代际、家庭月收入、家庭平均文化程度、家庭平均年龄。 |
| 8. | Female education is closely correlated with smaller family size , so the growth in the world ' s population should continue to slow as countries move towards “ replacement fertility ” and the population stabilises
女性的教育与更小规模的家庭紧密相联，这样一来在国家人口增长接近"更替生育率"时，人口数量就会稳定下来，全球人口增长的速度也因此会放缓。 |
| 9. | Then based on the analysis of the constructions of wh , go and ls sequences , the corresponding correlation properties are derived and methods of selecting subsets with good periodic mean - square cross - correlation property or aperiodic mean - square correlation property from the wh set and go sequence set whose go zone z = l are investigated . furthermore , the methods of truncating the go sequences to obtain the quasi - orthogonal ( qo ) set whose family size m is larger than the length l and the quasi - generalized - orthogonal ( qgo ) set whose size m is larger than li2z are discussed , together with the numerical results of the correlation properties
基于这些结果，探讨了如何从wh序列集和广义正交区z = 1的go序列集中，分别按照周期互相关均方特性最优和非周期相关均方特性最优的准则选择性能较好的序列子集；同时讨论了将广义正交序列截短来获得准正交( qo )序列集和广义准正交序列集( gqo )的方法，并给出了这一类序列相关特性的数值计算结果。 |
| 10. | The results indicate : the rural households " agri - productive investment behavior are generally affected by such factors : the rural households " basic family status , the rural households " owning resource , market terms , the different geographical environment and the external economy environment if other factors remain unchangeable , the rural households would increased their agri - productive investment scale in the next year by such terms : the rural households " family size get bigger , the rural households improve the educational level , the rural households decrease the opportunity in working in the second or the third field , the family agricultural opening revenue got increased last year , the rural households " productive capital assets got increased last year
假定其他因素不变：农户家庭规模越大，劳动力文化水平越高，农户非农业就业机会减少，农户上一年农业家庭经营收入提高，以及农户上一年生产性固定资产增加，都会使农户在下一年增加农业生产性投资；同时由于农户处于不同的地理环境、位置，也对农户进行农业生产性投资产生影响。同时本文对北京市政府制定相关农业政策提出以下建议参考： 1 、进一步稳固农户投资主体地位，同时，积极引导财政支农资金、银行贷款等其他投资形式向农业转移，形成资金互补机制。 |
