正常的球形胚和某些畸形球形胚继续发育，在心形胚或鱼雷胚阶段又出现出畸形胚，可以分为：①无茎端生长点；②原形成层发育不正常；③外形畸形，如有的是连胚，有的呈指状，有的呈叶片状等等。畸形胚有的败育，有的能继续发育，在子叶胚阶段形成畸形的植株。

Results It was found that the dense artery sign of MCA existed in the first CT scanning. The dense artery sign of MCA was like a"stick"or"punctiform", and its CT value was over 60 Hu. In the second CT scanning (24 hours after the first scan), a big area of low density in the region supplied by MCA was shown.

结果 26例患者发病早期（1～6h）的CT 检查均见一侧大脑中动脉致密动脉征，呈"条状"或"点状"，CT值大于60Hu；发病后24h复查，该侧大脑中动脉血供区均呈大片状低密度影。

On terms that the metal products were supposed to be scrapped according to the normal distribution with service life,the calculation method for the theoretical value of reclamation resource of depreciated metal was studied for the conditions that the relation between consumption volume of metal and time was linear and quadratic respectively.

在假设金属制品报废概率随时间呈正态分布的条件下，研究了金属消费量随时间变化呈线性函数或二次函数两种情况下，金属折旧再生资源量理论值的计算方法。

Experimental result shows that when the incident is vertically polarized, the head direction RCS average's variation along the relative curvature is of "W" shape and has 2 minimum values; when horizontally polarized, the head direction RCS average's variation is different in two bend fashions.

实验结果表明，垂直极化下头向雷达散射截面均值随弯度呈"W"形变化，有两个极小值；水平极化下两种弯折方式头向雷达散射截面均值变化趋势差异较大，上下弯折时呈"W"形变化，水平弯折时单调降低。

With the increasing of SA concentration,Chl content decreased,MDA content and cell membrane relative permeability increased significantly.

随着SA浓度的增加Chl含量呈下降趋势，MDA的含量和细胞膜透性呈上升趋势。

Purpuraristatus, the growth, fertility, chromosome configuration, EST isozyme etc. were analyzed in this paper. The results showed that the growth potentiality of (E. sibiricus×E. purpuraristatus) F2 and (E. purpuraristatus×E. sibiricus) F1 were much stronger than their parents, the plant height of the former was 143.2 cm. The whole plant was reseda, the latter was 129.7 cm. The spike nodding of two hybrids were in the middle of their parents, the anther was yellow; the pollen fertility was 0.02%~0.03%, seed set was 0; the average chromosome configuration of former pollen mother cell at PMC M Ⅰ was 6.90Ⅰ+14. 02Ⅱ, the latter was 7.82Ⅰ+13.59 Ⅱ, and lagging chromosome and bridge fragment were observed at meiosis anaphase Ⅰ the EST of the two hybrids F1 and their parents at tillering stage was some certain different in locus, number and intensity.

结果表明，正交F1和反交F1植株的生长势均很强，正交F1株高143.2 cm、全株浅绿色，反交F1株高129.7 cm、全株灰绿色；正、反交F1的穗型均呈双亲中间型，花药呈黄色，花粉可育率0.02%~0.03%，结实率为0，说明杂种高度不育；正交F1的花粉母细胞减数分裂中期Ⅰ平均染色体构型为6.90Ⅰ+14.02Ⅱ，反交F1为7.82Ⅰ+13.59Ⅱ，减数分裂后期丁有落后染色体和染色体桥等不规则现象；亲本及其正、反交杂种F1分某期幼叶的EST同工酶酶带的位点、数目和强弱均存在一定差异，可作为亲本及杂种在蛋白质水平识别的重要依据。

Influence of environmental factors on photosynthetic physiologic indexes and water use efficiency of winter wheat leaves was studied in semi-arid rain feed agriculture region in Loess Plateau. Diurnal fluctuation of physiological rate of leaf was a not obvious two-hump curve and diurnal fluctuation of transpiration rate was a typical resupinate "U" and the Pn and Tr in a.m.

通过对黄土旱塬冬小麦叶片光合生理指标、水分利用效率及其对环境因子的响应进行分析，结果表明：净光合速率日变化呈不明显的双峰曲线，蒸腾速率日变化呈明显的倒"U"型曲线，两者上午都明显高于下午，且不同生育期峰值出现的时间不同。
