The matched abundance ratio cascade theory was used to design the cascades.

应用匹配丰度级联理论的基本原理，计算了不同关键相对分子质量下的级联，分析了级联参数的变化。

Starting from 3-benzoyl-5-formyl-indolizine, 3-benzoyl-5-(2'2'-diacetylethenyl)-indolizines and analogs were obtained by the 〓mediated aldol condensation or Wittig reaction. These compounds,promoted by low-valent titanium, gave highly functionlizedcycl[3,2,2]azine derivatives. The coupling reaction proceeded betweenthe carbonyl group and the carbon-carbon double bond, a rare example inMcMurry reaction.

我们以3-苯甲酰基-5-甲酰基中氮茚为原料，通过三碘化钐促进的aldol反应和Wittig反应制备了3-羰基-5-羰基乙烯基中氮茚，随后经低价钛还原偶联，没有生成正常的分子内羰基-羰基偶联产物，而是得到反常的羰基与α，β-不饱羰基的双键偶联产物，较高收率地得到了含多官能团的CycI[3，2，2]azine衍生物。

In professional baseball , a bush league is a "minor league ", not a " major league " with first

在职业棒球运动中，一个灌木球联是个"小球联"而不是有着一级球员的"大球联"。

In professional baseball, a bush league is a "minor league", not a "major league" with first-rate players.

在职业棒球运动中，一个灌木球联是个"小球联"而不是有着一级球员的"大球联"。

But the cartoonist is making a pun here, as bush league is also "Bush league", second-rate because it comes from people with minds like that of President George W.

但是漫画家在此用的是双关语，因为灌木球联就是"布什球联"——一个二流的球联，因为它的人员组成都是

A numerical calculation method to solve the cascade equation was presented. Analytical solution to the cascade equation was obtained in the case of quasi-ideal cascades, that is, the cascades with a constant partial cut at all stages.

各级组分分流比不变的多组分级联称为准理想级联，得到了计算存在损耗的准理想级联中相对产品流、相对贫料流、级联中总物质流量以及产品流和贫料流中组分丰度的解析表达式。

Mounted coupling: first in the motor shaft mounted on the head ring, mounted on coupling half, and then in the shaft coupling client and loaded block chute and Plum wrench tightening bolts (lifting shaft 3 ~ 5 mm and to provide mechanical seal prestressed); and then loaded up the other half on the coupling screw Hexagon screw must be tightened.

装联轴器：先在电机轴头上装上挡圈，装上一半联轴器，再在泵轴端和联轴器槽内装上挡块并用梅花扳手拧紧螺栓（吊起泵轴3~5毫米并提供机械密封预应力）；再装上另一半联轴器拧上内六角螺钉必须拧紧。
