稀

An ICP AES method for the determination of Cu,Si,Al,P,Cr,Ni,Mn,W in ferrovanadium has been established, based on the selection of proper wavelength and background correction.

叙述采用等离子发射光谱法同时测定钒铁中的铜、硅、铝、磷、铬、镍、钨、锰等微量元素，试样用稀王水分解，选择适当的波长与背景校正进行分析测定，方法回收率在 95%～ 1 0 5%之间，相对标准偏差均小于 4%，本方法快速准确，精密度良好。

Hold on to good friends; they are few and far between

Let's say that the 'average' mother has one half ounce of foremilk (the thin, sweet milk produced at the beginning of the feeding that is high in lactose but lower in fat) and two ounces of hindmilk (the higher calorie, thicker milk that is produced as the milk lets down and moves through the ducts, collecting fatty particles).

我们通常认为一般情况下，妈妈有0.5盎斯的前奶（宝宝每次吃奶时先吃进去的比较稀且甜的，高乳糖低脂肪的乳汁）就会有2盎斯的后奶（随着奶阵的到来产生的富含脂肪的比较稠的乳汁）。

In the presence of NaH and in DMF, the acyclic crown ethers 1a and 1b were synthesized by the reaction of di-or triethyleneglycol ditosylate and o-methoxymethoxybenzyl alcohol, which was obtained from salicylaldehyde via the protection of the hydroxyl group with chloromethyl methyl ether followed by the reduction of the formyl group with NaBH4. The hydrolysis of 1a and 1b with dilute hydrochloric acid provided the diphenolic type acyclic crown ethers 2a and 2b respectively in good yield.

将水杨醛与碱和氯甲基甲基醚反应，再经过NaBH4还原，即制得邻苯甲醇，然后将其在DMF中与NaH和二甘醇二对甲苯磺酸酯反应，得开链冠醚1a和1b.1a和1b经稀酸水解，即脱保护而分别生成新的酚型开链冠醚2a和2b。
