Seed-flax variety CI. 2446 was planted at four different dates (Oct. 5, Oct 20, Nov. 5, Nov. 20) and four different densities (2250, 1800, 1350 and 900 plants/m^2) to study the effects on the fiber cell development at different growing stages. All traits, except the phloem thickness, of fiber cell showed no significant difference among different sowing densities.

以种子用亚麻CI2446为材料，分四种植期（10月5日，10月20日、11月5日、11月20日）及四种密度（2250、1800、1350、900株／平方公尺），以探讨其对种子用亚麻在不同生育期间纤维细胞发育之影响，由结果得知播种密度除对靱皮部厚度有显著差异外，对纤维细胞之其他性状影响并不显著。

The binding of different halide anions to four strapped calix[4]pyrroles was studied by means of molecular mechanics and molecular dynamics simulations methods. The results indicate that the anion binding ability of calix[4]pyrrole-type systems could be effectively tuned by modifying the length and nature of the bridging straps. In this process, it was the most stable conformation upon anion binding due to the formation of four NH\|halide hydrogen bond, simultaneity, the difference of cavity by modifying straps adapted themselves to different halide anion.

模拟结果表明，加入带状修饰链和调节链长可以增强对某种特殊卤素阴离子的识别，在这个过程中，卤素阴离子与杯[4]吡咯NH上的氢形成的多氢键使主体分子与阴离子形成稳定复合物，同时带状修饰链通过改变杯吡咯空腔大小影响主体分子与卤素阴离子的氢键相互作用，从而调节了对不同阴离子的识别能力。

For the 23 core biopsies suggesting phyllodes tumor, excisional biopsy confirmed the diagnosis in 19 but revealed fibroadenoma in four patients, for a positive predictive value of 83%. Final pathological analysis of the equivocal core biopsies diagnosed fibroadenoma in five patients and phyllodes tumor in four patients. Final analysis determined that none of the lesions were malignant.
