METHODS: 5 184 people of non-manual workers and manual workers in city as well as farmers at different sex, aged from 20-59 years, were selected in Shijiazhuang, Cangzhou and Chengde with random sampling of stratified cluster in July 2000. They were assigned into 20-39 year group and 40-59 years group according to age to perform investigation of their physical work, which composed of strength of grasp, anteflexion of body when sitting, standing with single foot when closing eyes, back pressure, vertical jump, 10 m×4 return run, push-up, sit-up and choice of reaction time, etc. RESULTS: 4 800 people were involved in the result analysis.

于2000-07用分层整群的随机抽样方法抽取石家庄、沧州、承德3个城市不同性别的城市非体力劳动者、城市体力劳动者、农民3类职业人群的20~59岁公民5184名,按年龄分为20~39岁组和40~59岁组两组,对其进行体能测查,测查内容包括握力、坐位体前屈、闭眼单脚站立、背力、纵跳、10m×4往返跑、俯卧撑、仰卧起坐、选择反应时等。

Antenatal diagnosis by Chorionic villus sampling can be done.

The result showed that the best time for sampling was 7 to 14 days after the first bud flowering on the main anthotaxy. The capacity of embryoid production varied significantly in different genotypes. Among them, twelve genotypes yield embryos successfully, which the rate could reach 71%. Genotype 102 was an ideal material for embryoid induction, and the frequency could reach 32.78 embryos per bud. Genotype that with a highest yield produced 546 times as many embryos as that with a lowest yield. The embryoid induction ability of normal bolting genotypes were higher than easy bolting and hard bolting genotypes.

结果表明:在秋冬季日光温室内,供试植株主花序第一朵花开后第7~14天取样,即初花期是最佳取样时期;不同基因型间小孢子胚胎发生能力差异很大,在接种的17个基因型中,有12个诱导出胚,诱导成功率71%;其中102号产胚量最高,达到32.78个/蕾;在已产胚材料中,产胚量最高的基因型是产胚量最低的基因型的546倍;较易抽薹型材料的产胚能力大于易抽薹型和不易抽薹型。

The effect of the steel sector weight is more apparent in period of an expansion cycle compared to that in a period of a whole economic cycle. The hypothesis was further confirmed during the course of data sampling. Overall, in the various stages of the economic cycles, as the weight of cash deposit decreases, the expected return of portfolio amplify, while the overall risk raises as well.B. The optimal asset allocation strategy, which is subjected to the current rules and regulations, imposed the authority.
