讨论了实际气体绝热节流系数的计算,节流系数可用计算法和作图法来确定。

Mapping of microsatellite markers in two wheat crosses segregating for Pm23 and Pm4b, respectively, in combination with the reported mapping of Pm4a, indicated that the three genes were all linked to the marker Xgwm356 with a distance of 3-5 cM. Allelism between Pm4b and Pm23 was then confirmed, when the progenies of a cross between VPM1 (Pm4b) and Line 81-7241, were shown to be all resistant to a B.

利用获得的8个标记对Pm4b进行遗传作图,结果表明,4个标记与Pm4b连锁(Xgwm356、Xgdm93、Xbar76和Xbarc122)。3个抗白粉病基因(Pm4a、Pm4b和Pm23)均与标记Xgwm356连锁,遗传距离为3-5cM,等位性测验证明Pm23与Pm4b为等位基因。

Leastsquare method and Lagrange's interpolation formula see their applicationsfor fitting fore-and-aft lines-whose aim is to calculate the intersection point ofequivalent inclined waterline-and differences. In order to replace theinconvenient alternate conduct of drawing and calculating, improvement hasbeen introduced into the paper which means all work can be done bycomputer. Capacity calculation cannot be done without boundary layer build-up. Fit every area curve and area moment curve is necessary because ofinterpolation.

A highly resistant primitive cultivated species Solanum phureja was employed to generate a mapping population to perform the bulked segregant analysis for screening of AFLP markers linked with the resistance. Another population which had genetic similarity to the mapping population was used for testing of the markers achieved.

以马铃薯青枯病高抗性的原始栽培种Solanum phureja获得的二倍体群体为作图群体进行AFLP标记的初步筛选,另选一个与作图群体有较大亲缘关系和相近遗传背景的二倍体群体对所获标记进行验证。

而对于变幅系统和曲线滑道活对重自重平衡系统的设计,传统意义上单纯的通过建立数学模型进行优化的方式来进行设计,或者单纯的作图法来设计,在很多方面暴露出弊端,如优化得到的点离实际需要的太远,或者作图设计速度较慢等,正因为如此,有必要对变幅系统和曲线滑道活对重自重平衡系统的设计重新做出一种新的尝试。

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称;三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起,称之为挽歌体诗人或者史诗诗人,他们被称为诗人,似乎只是因为遵守格律写作,而非他们作品的模仿本质。
