coanda effect
wall effect
Examples
- Although the relation is still main working system in the rural community interpersonal trust , under the influence of the social transition it also runs into corner . therefore the institutionalized trust in a certain degree has been accepted . as a result , institution and relation has together acted on trust and will in a long period predominate the rural trust working system
关系运作仍是乡村社区人际信任的主要运行机制，但在社会转型期效应的影响下，这一传统运作机制也开始陷入困境，制度化信任在一定程度上被接受，制度与关系共同作用于信任的二元格局出现，并会在相当长时期内主导乡村信任运行机制。 - Result shows , the uncertainty of parameter leads to negative ( positive ) investment horizon effects when investor ' s risk aversion is more ( less ) than that of logarithmic utility ; the effects of parametric uncertainty will weaken when investor uses more past data in his estimation , or when his risk aversion increases ; the effect of the first order moment ' s uncertainty is stronger than that of the second order moment ' s uncertainty
研究表明，当投资者的风险规避程度大于（小于）对数效用时，参数不确定性将导致负（正）的投资期效应；当投资者在估计过程中运用较多的历史数据、或者风险规避程度增加时，参数不确定性的影响将减弱；收益一阶矩的不确定性影响较其二阶矩强。 - The study on the characteristics of development and seed setting of different spikelet and floret positions was important for the realization of big - spike - cultural - goal with more spikelets and grains . with both the winter type ( wv ) and spring type ( sv ) varieties sown at different dates , it was found that the greater seed setting capacity of spikelets resulted in more grain number of spike . the trend of differences in grain weight per spikelet between the different sowing dates and varieties was similar to that of grain number . the correlation between the average grain weight of middle spikelets and lower spikelets and the grain weight per spike was highly significant . the environmental changes resulted from different sowing dates mainly effected the middle spikelets development , even though the differences between wv and sv were represented in every spikelet positions . the grain weight on the second floret position was most sensitive to the development status of wheat plant and environmental changes , and could represent the yielid potential of the whole spikelet . the results showed that the enhancement of seed setting of the middle spikelets ( from 5th to 15th ) and the grain development from the first to third floret positions was a key to realize big - spike and grain
确定小麦不同小穗位和小花位发育与结实特性是实现大穗多粒的重要前提.本文通过对冬、春性小麦品种分期播种试验得出,较高的小穗结实力是增加穗粒数的重要因素.不同播期、品种之间,小穗粒重和粒数呈现相同的变化趋势.中部以及基部小穗粒重与穗粒重之间呈高度正相关.体现环境差异的播期效应以对中部小穗发育的影响为主,而冬、春性品种的基因型差异可反映在各个小穗位上.第2小花位的子粒发育状况反映整个小穗的生产能力.结果表明,促进中部优势小穗(第5 15小穗)结实和第1 3小花位子粒发育是提高小花结实率和穗粒重的关键
