查询词典 mixing ratio

Unbraced Length Ratio means if the distance between lateral bracing. If the ratio is small, the capacity of the beam might reach 0.66Fy. If the ratio is small enough, it will reach 0.66Fy. On the other hand, if the ratio is high, then then capacity is low.

答：应该是平面外支撑的问题吧， Unbraced Length Ratio中的数值并不改变程序计算出来的结构的内力，但是却能改变杆件的承受力和变形的能力，数值越少，就是说不支撑的距离越短，承载能力也越强，那么 ratio 肯定就越小，结构会越稳定。

The principle component analysis showed that head rice ratio, amylose content, chalkiness ratio, gelatination consistency and protein content were most quality traits in low amylase content (5-15%), and head rice ratio, amylose content and chalkiness ratio were most quality traits in low amylase content (5-15%). Correlation of amylose content and 8 agronomic traits showed that: if single plant of low amylase was selected, its'agronomic traits would be affected in negative.

The apparent degree of network chains for the different swollen extent of the same unswollen hydrogel sample increased linearly with the increase of swelling ratio, however, the apparent modulus did not decrease monotonously with the increase of swelling ratio. Furthermore, the dependence of apparent degree of network chains on swelling ratio had nothing to do with the swelling agent. The above results reflected the changes of entanglement and the contribution of entanglement under different swelling ratio, and the results could be explained with the theory of Flory-Erman's constrained junction model and LangleyGraessley relation.
