外场与腔场非共振驱动Jaynes－Cummings系统的准能解

本文主要求出了Ｊ－Ｃ系统受与腔场非共振的外场驱动时的准能级及态的近似表达式，设外场与腔模的失谐量△_ｃ远小于耦合常数ｇ，并且腔模光子数较小，在计算中可略去。结果可知，失谐量△_ｃ存在使能级中心位置移动，但对能级分裂量没有影响。相应的光场态为两个位移福克态的叠加。     

灰铸铁的应力屈服曲面及其三维热弹塑性应力解析

海口市番茄反季节栽培品种比较试验初报

海口市番茄生产的正常季节是冬种春收。其产量虽然较高,但产值较低。本试验是通过引进耐热番茄品种,将播种期推迟到二月春种夏收,即反季节栽培。试种结果初步表明:泰引3号、扬帆2号等引进品种,在气温较高的条件下,植株生长正常,座果率较高,产量与品质能达到当地正常季节栽培的水平。我们初步认为,泰引3号比较理想,可在海口市郊进一步试种。     

Choroidal and iris angioarchitecture of the newt: A scanning electron-microscopic study of vascular corrosion casts

The corrosion cast technique provided for the first time an excellent three-dimensional visualization of the vascular pattern of the choroid and iris in the newt eye. The results show the presence of a single arterial afference to the choroidal and iris capillaries: the ophthalmic artery is the origin fo both ciliary arteries and the long posterior ciliary artery. Slightly behind the equatorial circumference of the eyeball the venous drainage consists of a single vessel on the dorsal side and two distinct vessels on the ventral one. It receives blood from both iris and choroid. The surface of the plastic endocasts shows some details of fine luminal structures of the endothelial cells. Shallow depressions may be regarded as imprints of endothelial cell nuclei, and they are distinctly different for arteries and capillaries. The angioarchitecture of the newt eye differs from that of brain in that hairpin-shaped capillary loops are not observed at all.

Phenological studies of selected savanna mosses of south-western Nigeria

It was established that there is little diversity of bryophytes in the derived savanna. Mosses were found in the sampling sites, whereas liverworts were rarely observed. The reproductive methods of four dominant sexually reproducing savanna mosses —Archidium ohioense, Bryum coronatum, Fissidens minutifolius andTrachycarpidium tisserantii were monitored over two consecutive rainy seasons. Protonemal and gametophyte production were noticed in the field in March/April, and capsule dehiscence and spore dispersal occurred in September/October. The sequential stages of development, starting with gametangial production and ending with the falling of the dehisced capsules, occurred within the rainy season. However,A. ohioense andT. tisserantii did not discharge their spores easily (cleistocarpous), unlike the stegocarpous speciesB. coronatum andF. minutifolius. Water availability and possibly high humidity may have contributed to growth. The short period between sex organ formation and dehiscence of capsule seen in these studies, compared with the longer period in some temperate mosses, may be an advantage for bryophytes in a savanna environment.     

生长调节剂对大叶白蜡幼苗生长的影响

对一年生大叶白蜡实生苗用3种不同浓度的赤霉素（GA3）、ABT生根粉7号（ABT7）、萘乙酸（NAA）进行处理。结果表明，3种生长调节剂对大叶白蜡幼苗生长有明显的促进作用。处理后的苗木提高，生长加快，茎干增粗，叶片增大，抗性增强，其中以50mg/L的GA3作用最为显著。
