查询词典 yield rate

When row spacing was fixed and spacing of plant was increased properly, Fo was decreased, Fv and Fm and Fv/Fm and Fv/Fo were increased, the net photosynthetic rate and yield were increased, but it had no remarkable effect if spacing of plant was increased fulsomely.

在同一行距条件下，适当增加株距，会引起Fo的降低，Fv，Fm，Fv/Fm和Fv/Fo的增加，提高了净光合速率，有利于产量的提高，但过分加大株距效果不明显。

The effect of different reaction conditions,such as catalyst concentration,molar ratio of reactants,reaction temperature,reaction time,on the coupling reaction of trioxane and methyl formate synthesizing methyl glycolate and methyl methoxy acetate using sulfuric acid as catalyst has been studied.Through the analysis for the yield of products and system pressure,and comparison with other different acidity catalysts,we considered that the activation of formaldehyde was the control step of reaction rate to the...

以硫酸为催化剂，研究了三聚甲醛与甲酸甲酯偶联合成乙醇酸甲酯和甲氧基乙酸甲酯的反应中，催化剂浓度、原料配比、反应温度、反应时间等条件对反应过程的影响，通过对产物收率和系统压力变化的分析，并结合与其它不同酸强度催化剂的对比，得到甲醛的活化是偶联反应的速率控制步骤，催化剂的酸强度决定其对甲醛的活化能力，是影响偶联反应的主要因素。

Hydrastine(97.7%) was obtained with extracted rate 65%by extracting the Goldenseal with mixed Solvent;Berberine hydrochloride (99.9%) was obtained by adding hydrochloride acid to alcohol (alcohol∶H 2O=1∶1) solution of the extract and Hydrastine (99.5%) was gained by CLC method with the yield 1%.

原药材用混合溶剂直接提取分离，可得到含北美黄连碱 97.7%的结晶体，提取率达 6 5%；提取物经醇水溶解、酸化，可直接获得小檗碱盐酸盐结晶，纯度达到 99.9%；用柱色谱法，可得到 99.5%的北美黄连碱，收率约 1

Therefore it is assumed that the coupon payments can be reinvested at this average rate, i.e."interest on interest" is at the gross redemption yield.

因此，假定利息可以在这个中间汇率基础上再次投资，换言之，赎回毛收益将包括"利息的利息"。

The gross redemption yield of a bond is simply the average rate at which the sum of the future coupon payments and redemption proceeds are discounted to equate their value to the current market price.

赎回毛收益率是指将未来票息利率与赎回收益总额折现为当前市场价格的中间汇率。

In maintaining advantages in cotton breeding suitable to spinnin middle-count yarn, breeding research for cotton varieties suitable to spinning high-count yarn and middle-low-count yarn should be strengthened, and new varieties must be resistant to Fusarium and Verticillium wilt and cotton bollworm and must have high rate of cotton yield before frost, and emphasize the applicalion of transgenic breeding technique in future.

今后应在保持适纺中支纱棉花新品种选育优势的同时，加强适纺高支纱和中低支纱棉花新品种选育，育成品种必须抗枯、黄萎病，抗棉铃虫，霜前花率高，增强稳产性和适应性，并重视转基因育种技术的应用。
