Since mineral N is assimilated more efficiently than N2, increasing soil N supply can lead to more photoassimilate being available for shoot growth and leaf development Trolley-Henry and Raper, 1986, Cassman et al.

由于矿质N比N2可以被更有效地同化利用，增加土壤氮素供应可以导致更多的光合同化物供给植株地上部分的生长和叶的发育（Trolley-Henry和Raper，1986，Cassman等1980）。

The test result shows:(1) Concentration after grind finely, multi product configuration, regrind and reconcentratipn of sulphide iron ore, and firstly recovering tin and removing sulfide ore as possible as are available metholds to improve the grade and recovery of tin concentrate, simplify technology flowsheet and reduce production cost;(2) Intensifying the recovery of single stage concentration table is the key to concentration to concentration after grind firely and improving index. The recovery of fine tin is sure to further improve index;(3) Regrind and reconcentration of ferro-sulphur ore may recovery some tin.

试验研究结果表明：(1)细磨入选，多产品结构，硫化铁矿物再磨再选，能拿早拿、能丢早丢，预先脱出硫化矿物是提高锡精矿品位和回收率，简化工艺流程，降低生产成本的有效途径；(2)强化一段摇床的回收是细磨入选，提高指标的关键，细粒锡石的回收是进一步提高指标的根本保证；(3)硫铁矿物再磨再选也可回收部分锡金属。

These findings provide a potential physiological basis for cardiac resynchronization therapy in this patient population.

这为CRT治疗在这部分人群中的有效应用提供了潜在的生理学依据。

Part 1: On image compression coding 1 Based on human visual property, we present a rhomb-partitioning fractal image compression coding, discuss fractal image coding of fixed-size rhomb partitioning and adaptive rhomb partitioning.

第一部分是有关图象压缩编码的： 1基于人眼的视觉特性，提出了基于菱形分割的分形图象压缩编码方法，讨论了固定菱形块分割图象·自适应菱形块分割图象的分形图象压缩编码问题，实验结果表明菱形块分割图象比方块分割图象更有效地抑制"块效应"，重建图象质量明显提高，但编码时间较长。

The first phase array ofthe AS γ experiment began to run in June 1990. The first phase array thatconsists of 49 plastic scintillate detector has an angle resolution of 1°, atrigger rate of 20Hz and a threshold energy of about 10TeV. The second phasearray was finished on the base of the first phase array in 1994, and after that, apart of the second phase array was made high density.

一期阵列由49个塑料闪烁体探测器组成，探测阈能为10TeV左右，事例触发率为20Hz，角分辨率小于1°。1994年在一期阵列的基础上进行了扩建，扩建后阵列比一期阵列有效面积增大8倍，随后进行了部分加密，建成二期／加密阵列。

Simple adjustments allow the most efficient use of material,and the selvage is automatically collected onto a spool for easy disposal.

简单的调节能容许材料最有效地被使用，而边缘没有用上的部分将会自动收集在卷筒上，方便清理处置。

The best method for isolation and purification of β-dihydroagarofuran sesquiterpene in Celastrus angulatus is alternate normal-phase and reserve-phase high performance liquid chromatography.

结果表明，对苦皮藤中富含二氢沉香呋喃倍半萜类化合物部分进行分离的过程中，采用正相、反相高压制备柱层析交替进行的方法最为有效。

The non-uniform algebraic codebook is determined by the non-uniform statistical properties of the algebraic codebook, and the part-searching-area is determined by the periodicity of the algebraic codebook excitation vector, which makes up the insufficient numbers of signed pulses in algebraic codebook at low bit rate.

非均匀代数码书由代数码书的脉冲非均匀统计特性确定，部分搜索域代数码书则由代数码书矢量的周期性确定，该方法有效地弥补了低比特率情况下代数码书中脉冲数不足的缺点。
