In this paper, male sterile line of alfalfa was used to be improved with crossing, because the seed production of crossing is low. The affecting factors of seed production of male sterile line of alfalfa and its crossing progenies that are crossed with male sterile lines of alfalfa and good alfalfa that male is fertile were analyzed. The characteristics of female reproductive organs of male sterile line and its crossing progenies are analyzed in cell morphology. The genetic difference of male sterile line and its crossing progenies are analyzed in enzyme protein. The results showed: 1、Rate of podding of nature crossing and fecundity of artificial crossing of the male sterile plant BC1-2 that is the crossing progency of male sterile line of alfalfa and Medicago varia Martin.cv.'Caoyuan No.1'is higher than male sterile lines. Rate of podding of nature crossing and fecundity of artificial crossing of the male sterile plants BC1-19、BC1-21、BC1-22、BC1-23 that are the crossing progencies of male sterile line of alfalfa and Medicago sativa L.cv.

针对苜蓿雄性不育系杂交制种产量低的问题，采用杂交法对苜蓿雄性不育系进行改良，以原苜蓿雄性不育系为轮回亲本与雄性可育优良苜蓿品种杂交，分析苜蓿雄性不育系及其杂交后代种子产量的影响因素，从细胞形态学方面观察和分析杂交后代及原不育系在雌性生殖器官上的变异特点，从酶蛋白水平对杂交后代及原不育系的遗传差异进行分析，初步研究结果如下： 1、苜蓿雄性不育系与草原一号苜蓿的杂交后代不育株BC1-2，以及苜蓿雄性不育系与X′(苜蓿雄性不育系与新疆大叶苜蓿的杂种F1代)的杂交后代不育株BC1-19、BC1-21、BC1-22、BC1-23的天然杂交结荚率和人工杂交制种的结荚率和百粒重均高于原苜蓿雄性不育系。

The ever more popular Eurostar between London and Paris, Spain's expanding network of AVE high-speed trains, the ICE network in Germany – just as we are beginning to understand that criss-crossing the world by air may leave very little of the world for our children to criss-cross at all, it looks as though an older, slower, greener and altogether more satisfying way of travel has smartened up its offerings.

伦敦与巴黎之间的欧洲之星越来越受欢迎，西班牙的AVE高速铁路网正在不断扩大，而德国也开通了自己的城际列车特快(Inter City Express，简称ICE)。飞机在空中的穿梭往来，也许会让今后的孩子们彻底失去旅行的空间。当我们开始懂得这一点的时候，似乎就能够看到：一种老派一点、缓慢一点、环保一点、并且总体说来更令人满意的旅行方式，就足以提供种种格外诱人的东西。

A new dimensionaless parameter, called the threshold-crossing intens ity, is defined as a measure of the threshold-crossing severity, which is equal to the ratio of the product of average number of crossing events per unit time a nd mean threshold-crossing duration and amplitude over the threshold.

定义了一种度量过阀严重程度的新指标，称为"过阀强度"，等于单位时间过阀平均次数、平均过阀延续时间和平均过阀幅值三项乘积与阀值之比。
