Lanthanides belong to the sixth cycle of the periodic table Ⅲ B family, are all solid metal, they are La, Ce, Pr, Nd, Pm, Sm, Eu, Gd, Tb, Dy, holmium, erbium, thulium, ytterbium, and lutetium were 15 kinds of metals and their periphery are two layers of electronic 5d16s2, while the peripheral third layer f orbital but never zero to 14, so the external electronic structure of 4f0-145d16s2, and therefore these elements in oxidation number are to 3, very close chemical properties, extraction, when it is difficult to separate them they are mostly multi-element mineral mix, more difficult to increase refining, and their atomic number of 57-71, one by one to increase the number of protons the nucleus, and thus extranuclear electron of gravity is also growing, so that atomic radius decreases with increasing atomic number Z, which makes lanthanides contraction, ionic radius is also reduced, which also makes Zr, Hf, Nb and Ta, Mo and W, the atom and ionic radius very close to each other they also determine a similar nature, resulting in difficult separation, also the tribe Ⅷ of the fifth cycle, ruthenium, rhodium, palladium, and the sixth cycle, osmium, iridium, platinum is very similar in nature, thus The six elements, said platinum group elements.
镧系元素属于周期表第六周期中ⅢB族,全部是固体金属,它们是镧、铈、镨、钕、钷、钐、铕、钆、铽、镝、钬、铒、铥、镱和镥共十五种金属元素,它们的外围两层的电子均是5d16s2,而外围第三层的f轨道电子却从零增加到14个,所以外围电子结构为4f0-145d16s2,而使这些元素氧化数均为+3,化学性质极为接近,提炼时很难分开,它们的矿石又大多是多种元素混在一起的,更增加提纯难度,它们的原子序数为57-71,核内质子数逐个增加,因而对核外电子引力也不断增强,使原子半径随原子序数Z增加而减小,这就使镧系元素收缩、离子半径也缩小,这也使得Zr和Hf,Nb和Ta、Mo和W等原子和离子半径都很接近、也决定了它们彼此性质类似,以致难以分离、也使第Ⅷ族中第五周期的钌、铑、钯和第六周期的锇、铱、铂在性质上极为相似,因而称这六个元素为铂系元素。

None of the four models could work well in the scenario 2, under explored stock, however they got accurate results in scenario 1, regulated stock. The Schnute model work well in full explored stocks such as scenario 1, 3, 4 and 5, especially in low biomass stocks such as scenario 3, but not suitable to the under explored stocks such as scenario 2. The W-H model generally performed well in all kind of scenarios especially in scenario 1, 4, and 5. In the swordfish, xiphias gladius, fishery, estimation of W-H model and D-Fox model produced MSY about 14000 ton, very near the result of Prager in 1996.The author tentatively explored the suitable fishing condition for the models to stock assessment.
四种剩余产量模型在充分捕捞且管理良好的渔业1中评估效果较好而在捕捞不足的渔业2中效果较差;Schnute模型在充分捕捞的渔业如渔业1、3、4、5、尤其是在低生物量的渔业3中评估效果较好,但不适合评估未充分捕捞的渔业,如渔业2;Walters-Hilborn模型适用于各种渔业,尤其是渔业1、4、5;在过度捕捞渔业中如渔业3、4,模型对参数q的估计较其它参数接近真值;在北大西洋箭鱼渔业的评估中,W-H模型和D-Fox模型对MSY的估计约为14000吨,接近于Prager(1996)的结果。

Another result of the study is that the total rate of entering a higher school is 74 percent, 69 percent, and 86 percent. For educational opportunities, the second group is most unequal when the rate of entering a higher school increases up by 50 percent. Through the analysis of logical regression beta b, the change in the inequality of opportunities of years of education in Taiwan is mainly influenced by various sharp structures of a total rate of entering a higher school, and not by the inequality of educational resources. When the rate of entering higher school is nearly 50 percent, the opportunity of years of education is most inequal.
本研究进一步分析各年代的整体国中后升学机率,分别为74%,69%,86%,以第二组年代的升学机率最接近50%,教育机会也最不均等;而根据逻辑回归系数 b 值的分析结果,发现台湾地区民众教育资源分配之不平等性并没有明显一致的变化趋势,前述受教育年数的机会不平等性之变迁,并非受教育资源分配不平等性的影响,而主要受到整体升学率不同的钜视结构影响,在升学率最接近50%时,受教育年数的教育机会最不均等。

The calling and copulation behaviour of Ancylis sativa Liu had a dielperiodicity.The female moths began to calling at the first day and increasedto 100% at the second day,then the percentage of calling decreasedgradually from the third day to the fifth day,only 16.7% of females showingcalling behaviour at the sixth day.The effect of environmentaltemperature on calling behaviour of Ancylis sativa Liu was studied duringadult life at 16℃,21℃,26℃ and 31℃.The result showed differenttemperature during adult life affected significantly the calling behaviour ofvirgin females.There was considerable variability in the calling patternsamong the different temperature groups,the higher the temperature was,thelater females called,the shorter the calling behaviour lasted.The copulationbehaviour of Ancylis sativa Liu can be divided into following squence:female calling,male responsing,male approaching female,hairpencil displayingand copulating.

The results show that the best sintering process for SiC preform is 1100℃, 8 h in vacuum, by which the open porosity is 99.6% and the preform strength reaches 0.57MPa. The thermo-physical characteristics of 57% SiC/Al composites produced by this technique are as follows: the relative density is 98.7%; the thermal expansion coefficient is 7.5×10^(-6)℃^(-1) which almost matches those of GaAs and BeO; the thermal conductivity is 1.65×10^5W/K, which corresponds to that of Cu(15%)/W and decuples that of Kovar alloy; the density is close to that of aluminum and less than that of one fifth of Cu/W.

The temperature gradient is larger in case ofussual half-zone model which has a uniform temperature distribution on the hot rod,andmodified half-zone model which has a non-uniform temperature distribution in the hotrod and negative radial temperature gradient near the axis of the hot rod.
模拟半浮区模型提出选择热传导系数与试验液体相当的材料作为热端棒材,使得热端内侧的轴向温度梯度接近于零。模拟半浮区模型的温度分布更接近于全浮区温度分布的一半。对于改型半浮区模型,选择热传导系数高于试验液体值一个数量级的材料作为热端棒材,使得热端温度分布不均匀,并且热端内侧温度高于外侧温度。
