With a view to locating the lowast state of trebly ionized cerium, the absorption spectra of CeCl3, and Ce2(SO4)3 solutions are examined between 2,000 A and 10,000 A. While no absorption was found in the long wave length side up to 9500 A, a new broad absorption region was observed, with center at about 2105 A. It is suggested that this and the four other similar absorptions observed by Freed are not related with the transitions which probably lie in a region not yet covered in this study.

本文从理论及实验方面讨论Ce~(+++)之最低能位问题。从CeCl_3及Ce_2(SO_4)_3溶液,除Freed氏已得之四吸收带外,在2105A处更薄现一阔而漫之吸收带。在红外方面,则直至9500A尚无吸收光线。因各种理由,似可证明Ce~(+++)之4f~2F—5d~2D线,与各外吸收无关而应在1至10μ间。

本试验就成都南郊金陵大学农场利用箱具装置以求降雨,坡度及作物种类对于四川棕土冲蚀之关系,试验自1941年须始至1945年年底为止,本报告包括1942至1945年四年记录;最初一年记录仅供参考未列入计算。试验中之箱具係木制,长1.8公尺,宽0.35公尺,深0.33公尺,共四具,分别置于5%,10%,20%及30%之四种坡度上,内盛四川红色盆地中之一种棕色粘土。降雨之时,每廿小时测定雨量,逕流及土壤冲矢量各一次,试验中192及1943两年行播芝蔴代表茎葉稀疏之作物,1944及1945年密播大豆代表茎菜密茂之作物。四年结果中之要点如下:(i)本试验四年中成都年降水量总平均为959.9公厘,最少年为689.9公厘而最多年为489.8公厘,本试验芝蔴年度平均降水量为734.0公厘,而大豆年度平均降水量为1185.8公厘。(ii)成都降雨烈度可暂按廿四小时内雨量,分为0—3.9m.m.,4—7.9m.m.,8—11.9m.m.,12—23.9m.m.,24—17.9m.m.,4(?)—95.6m.m.,96—191.9m.m.,等七级,四年中廿四小时内最多雨量可自84.2公厘至183.2公厘不等,此项烈雨可降于六月初至八月底之间,廿四小时内大于24公厘之雨日可自七日至十七日不等。(iii)芝蔴年度年降水量虽较大豆年度为低,但逕流占年雨量百分数,依坡度顺序,则前者各为16.95%,19.23%,25.71%及27.66%而后者各为3.96%,9.06%,9.63%及10.62%。(iv)四年中逕流量之实际数值,依坡度顺序,芝蔴年度各为129.11公厘,143.79公厘,193.54公厘及216.64公厘,而后者各为53.37公厘,120.59公厘,121.60公厘及135.07公厘。逕流逐月分布隨雨量分佈而变异,惟大豆作物有使逕流分佈百分数,向各月分散之趋势。又芝蔴年度七月份或八月份之逕流量可占年逕流量70%以上。(v)逕流之大部由于廿四小时内大于24公厘之雨量所发生,各坡度上大于24公厘之烈度等级中,在芝蔴年度,其分佈百分数之和幾全人於80%,而在大豆年度,其分佈百分数之和,自约38%至90%以上不等。芝蔴年度逕流量之实际数值较大豆年度为大,但逕流量隨坡度增加之比率则芝蔴年度较大豆年度为小。(vi)土壤冲失量之实际数值,依坡度顺序,芝蔴年度各为每市亩773.91市斤,832.5市斤,2004.93市斤及2822.62市斤,而大豆年度各为每市亩270.02市斤,370.50市斤,666.53市斤及762.95市斤,大豆年度中雨量特別丰沛之年,大豆护土力在大坡度上(坡度30%)更为显盖。(vii)芝蔴年度月雨量对于土壤冲矢量之影响大于对于逕流量之影响,月雨量增多,使同月土壤冲失量增加之百分数较使同月逕流量增加之百分数为大,大豆年度则反是。芝蔴年度土壤冲失量之实际数值较大豆年度为大,目土壤冲失量隨坡度增加之比率,芝蔴年度亦较大豆年度为大。(viii)据本试验情形,某一日之前五日内如降落巨雨,则该日急雨可发生甚大量之逕流及土壤冲失,芝蔴年度此种情形甚显,但大豆年度则不显。(ix)大豆作物之护土力,由于宽阔平向之叶面及密茂之莖叶可遮蔽地面以防雨滴之打击,而落叶护土亦可使地面流水澄清而维持土壤之渗漏速率,又麦稈覆盖地面之护土效力甚宏,如于大豆莖叶向未郁閉之前用之,可防初夏急雨之冲蚀。(X)自成都向南至仁寿县一带之棕土斤陵地,可行玉米与大豆等高行栽之间作制,惟大豆宜密植以收护土之效,若能于生长前期,地面覆盖麦稈,则土壤冲蚀之害可大减。

蓝小灰蝶在广西柳州沙塘是因种野百合属绿肥豆荚的主要害虫。此外该虫还为害木豆、刀豆和扁豆。根据文献该虫也为害荷兰豆和蚕豆。 小灰蝶和豆荚螟为害绿肥豆荚的特征和区别文中有详细的叙述。 小灰蝶以卵态在绿肥的花苞、嫩荚、茎和叶上越冬。幼虫为害豆类的时期自3月下旬直至12月上旬。在饲育室内一年发生7—8代。一世代需时20—176日。 成熟绿肥豆荚被害率自1.8—22.6%不等,本虫更为害花朵和嫩荚,使之凋落,不能结实。 绿肥作物终年开花结荚,不独是小灰蝶越冬的理想寄主,也助长其他重要豆作害虫如豆荚螟的繁殖。作者建议及时和合法刈割绿肥是解决本虫和若干其他豆作害虫的有效方法。
