In this paper, different leaching procedures were used for the chondrules and chondrule fragments of Semarkona, and the U-Th-Pb compositions of leachates and residues were analyzed by TIMS method. The residues normally give higher 206Pb/204Pb ratio, suggesting higher radiogenic Pb compositions. These residues form a Pb-Pb isochron, and give an age of (4566.9±5.8) Ma with MSWD of 26, consistent to the weighted average age of 207Pb/206Pb model ages.

在本文中，对Semarkona中球粒用不同的化学浸洗流程，并测定浸洗溶液和残渣中U-Th-Pb同位素组成，其中浸洗后的残渣均给出相对较高的206Pb/204Pb比值，表明其中含有较多的放射成因Pb同位素组成，这此残渣构成Pb-Pb等时线，给出年龄为(4566.9±5.8)Ma，MSWD=26，与207Pb/206Pb模式年龄在误差范围内一致。

The results are as follows: 1 mean length and weight tend to increase while dominant length and weight groups are noted to be increasing from Oct. 2004 to Sep. 2007; 2 by using length-weight formula, calculated weight value at the same length is higher for track-data than that for background-data; 3 growth parameters of L∞, W∞ and K respectively increase from 140.5 mm, 36.5 g and 0.28 a-1 to 186.0 mm, 118.5 g and 0.36 a-1 after artificial reef deployment; 4 appreciable increases are noted in body length and weight growth rate after artificial reef deployment, and inflexion age of weight growth increases from 2.55 to 2.58 years after artificial reef deployment; 5 there is an increase in critical biomass age from 3.21 to 3.77 years after artificial reef deployment; 6 there is a decrease in total instantaneous population mortality from 1.065 to 0.75 per year after artificial reef deployment; and 7 the overall population biomass of small yellow croaker stands at 131.5 tons.

结果表明：投礁后小黄鱼的平均体长和体重均呈上升趋势，优势体长组和体重组均向高值移动；同等体长情况下由投礁后体长体重关系式估算的体重比用投礁前的体长体重关系式估算的值大；投礁后小黄鱼个体生长方程的参数 L∞、W∞、K 值分别从投礁前的140.5 mm、36.5 g和0.28 a-1增加到186.0 mm、118.5 g和0.36 a-1；投礁后体长与体重生长速度与投礁前相比有所增大，且体重生长的拐点年龄从投礁前2.55 a提高到2007年的2.58 a；小黄鱼种群生物量增长的临界年龄从投礁前的3.21 a提高到3.77 a；小黄鱼种群的总瞬时死亡率从投礁前的1.065 a-1减小到0.75 a-1；鱼礁区小黄鱼资源量约

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.
