粗砂石

There was the guy with red hair and big steaklike hands that walked with me arm in arm through Washington Square Park, kissed me on the stoop of my mother's brownstone and said he wanted to be my boyfriend. Until our next walk, when he kept his hands to himself and said he meant boyfriend "in the theoretical sense of the word."

有一位曾同我手挽手走过华盛顿广场公园的红头发、手指如牛排那么粗的男子在我母亲的赤褐色砂石房子门口楼台阶上吻了我并说他希望成为我的男朋友，可还没等到下一次同他散步他就把手缩了起说他说"男-"朋友是指"纯理论上"的。

Also, it is heavily used for separating tin and tungsten ores. Besides, jigging method is introduced to handle gold,,tantalum, columbium, titanium, zirconium and chrome bearing primary ores and to separate placer with desirable results achieved.

对于金属矿石，是处理粗、中、细粒铁矿、锰矿的主要方法之一，并大量用于选别锡、钨矿石；跳汰法在处理含金，钽铌、钛、锆、铬的原生矿石和砂石的选别亦能获得良好效果。

Based on SIMPLER algorithm in the curvilinear body-fitted coordinates, the calculations were performed for Pr=0.7, Re=10~1000 on non-orthogonal non-staggered grids which are generated by elliptic equation systems.

采用曲线坐标系下压力与速度耦合的SIMPLER算法，数值研究了周期性渐扩渐缩波纹通道内脉动流动与换热情况，流动Re数的范围为10~1000，Pr数为0.7。
