维生素D是激素和，因此那些是非常好的与胰岛素融合的性致。同样的忠告从在5月出版的2，750项研究做了回馈，说明一天摄入2000IU的维生素D可能减少肠癌症和乳腺癌的几率。

Results For callus induction of leaf explants of C. orchioides, dark treatment gave better results compared to light treatment; among the media tested, the suitable phytohormone combinations were 2.0 mg/L 2, 4-D or 6-BA 1.5 mg/L 2, 4-D 2.5 mg/L, and 300 mg/L CH 0.2% AC was good for plantlet regeneration from leaf explants. The callus from leaf explants mainly originated from midrib. The parenchyma cells near epicuticle of midrib firstly were initiated to division. Then the parenchyma cells of vascular bundle sheath and mesophyll cells on each side of vascular bundle were also divided to form callus.

结果对仙茅叶片的愈伤诱导，黑暗的效果好于光照；在所试验的培养基成分中，适宜的激素配比是2.0mg/L2，4-D或6-BA1.5mg/L 2，4-D2.5mg/L，并且附加300mg/L水解酪蛋白和0.2%活性炭，对于仙茅叶片的离体成苗较好；培养后，愈伤组织主要由叶片的中脉产生，位于中脉上表皮内侧的薄壁细胞首先启动分裂，随后维管束鞘薄壁细胞及其外侧的叶肉细胞也启动分裂，参与愈伤组织的形成。

The investigation shows that the microstructure of ZAC27 alloy evolves as follows: after 1 day ageing,α phase,η phase and ε phase appear in the alloy, moreover, the amount of α phase,η phase and ε phase increase with the increasing of ageing time; after 10 d ageing, the β phase decomposes and vanishes completely in the alloy; after 50 d ageing, phases gather and form the coarser equilibrium microstructure which consists of near equiaxed, shot club-shaped α,η and ε phase.

On the basis of comparing the feature of inrush current's grille curve with that of fault current, a novel transformer protection scheme is proposed, which is not affected by add-assist circulation current at delta side on Y/D connection transformer.

在比较励磁涌流与短路电流网格曲线各自特点的基础上，提出了一种新型变压器保护方案，该方案不受Y/D接线的变压器D侧环流助增作用的影响。

According to "EPA Fate, Transport and Transformation Test Guidelines, OPPTS 835.3170—Shake Flask Die-Away Test" and "OECD Test Guidelines of Chemical 309", a simulated biodegradation experiment was conducted with the organic pollutant parathion-methyl. First-order biodegradation rate constants for water and sediment were -0.053 and -0.295 d-1, respectively, and half-lives were 13.1 and 2.3 d, respectively.

试验结果表明，甲基对硫磷在天然地表水中生物降解一级速率常数为：-0.053 d-1；在天然地表水沉积物中生物降解一级速率常数为：-0.295d-1；在地表水中生物降解半衰期为：13.1d；在地表水沉积物中生物降解半衰期为：2.3d。

The diagnostic of DT fuel plasma areal density in the direct-driven implosion experiments on SG-Ⅱ laser facility has been performed by measuring the number of recoil D and T produced by 14MeV neutron′s scattering. The particles of recoil D and T were detected by CR39 solid-state nuclear track detector.

在神光Ⅱ基频光直接驱动内爆实验中，利用CR39径迹探测器测量了DT靶丸释放出的 14MeV中子弹性散射后逃逸出燃料的反冲D核和反冲T核的数量，实现了激光聚变实验中燃料面密度〈ρR〉的诊断。
