William stoughton ( 1631 - 1701 ) of massachusetts declared that " god hath sifted a nation that he might sent choice grain into this wilderness . 马萨诸塞州的威廉斯托顿（ 1631 - 1701 ）说“上帝已经选择了一个国家，让他可以把精选的谷粒种植在这片荒土上。 ”
The above results suggest that the photosynthesis of the hull may contribute to grain filling and the development state of the hull may directly affect grain filling 以上结果表明，水稻在结实过程中，谷粒充实所需的物质至少有相当一部分来自于谷壳的光合作用，并且谷壳发育的好坏亦能直接影响谷粒的充实。
All this was new information , but even more surprising was this : to fit the observed anisotropy , the grain - like texture of the inner core had to be much more pronounced than previously thought 所有这些是新的信息,但是更令人惊讶的是这个事实:它跟观测得来的各向同异性相吻合,谷粒状的内核比先前的想法更能站住脚。
The optimized sieve parameters reduce the vertical amplitude of the sieve back - end , making the grains go easily through the sieve pores to be separated , and consequently help to reduce the grain loss rate and impurity rate 优化后得到了较优的振动筛参数，有利于减小振动筛后端的垂直振幅，使得谷粒更容易穿过筛孔完成分离，有利于减小损失率和含杂率。
Abstract : the pot - experiment shows that the coated - and mixed - fertilizer applied to rice only once can meet the need of rice in its various growth periods and increase the yield of rice 文摘:盆栽试验表明，一次性水稻专用涂层复混肥一次性施用能满足水稻各生育期的需要，并能促进养分由稻秆向谷粒的转移，提高成穗率和产量，使用方便，节省劳力，有较好的推广应用前景。
A swoop of six arrives on motionless wing from their roost site in a nearby river , drop lightly to the ground amid the others , and lower their heads to pluck the scattered corn , flashing their brilliant caps of crimson like blood on snow 六只丹顶鹤从附近河中的巢址翩然而至，轻盈地在其它鹤群之间落地，低头啄食四散的谷粒，露出一顶顶艳红色的头冠，一如雪中之血。
