Treatments were as follows: fertilization during leaf-expansion period, fertilization during green-leaf period, and no fertilizer. Results showed that individual leaf area, thousand-leaf weight, and leaf distribution were relatively stable with little influence from fertilization. Fertilization during leaf-expansion compared to the green leaf period significantly increased leaf number, leaf weight per plant, and leaf area index. Fertilization during led-expansion also significantly increased the total weight of leaves corresponding to each branch. The 14th to the 17th branches had the largest number of leaves in the canopy with fertilization increasing the weight of each branch but not changing the center of the canopy.
结果表明:毛竹单叶面积、千叶质量和叶片分布受施肥的影响较小,是较为稳定的指标;展叶期施肥处理(处理1)能显著增加单株立竹的叶片数量,到7月底,其单株立竹叶片总质量和叶面积指数分别比绿叶期施肥(处理2)提高14.8%和13.7%,比不施肥提高27.6%和24.5%;冠层14~17档是单枝叶片数量最多的区域,施肥能增加各枝盘叶片的质量,但对林冠重心的分布无影响;单叶叶面积稳定后(6月),处理1的叶绿素测定值和光合速率显著高于处理2和对照,而处理2与对照间无显著差异。

Two polar nuclei move to the micropylar end before sperm is released in a gap between the egg cell and central cell and subsequently taking off cytoplasm one after another. The sperm nucleus moving to the egg nucleus runs faster than the one to the polar nuclei. It fuses with the polar nuclei that are moving towards the antipodal cells at the chalazal end, Images showed the fusion process of male and female nuclei and polyspermous fertilization.
精子释放前,两极核移向卵细胞的合点端;两精子释放于卵细胞与中央细胞的间隙后,先后脱去细胞质,然后分别移向卵核和极核,移向卵核的精核快于移向极核的精核;精核与两极核在向反足细胞团方向移动的过程中完成雌雄核融合。

The presence of phosphorylated ERK1/2 in nucleus, cytoplasm, neurites suggests a role for ERK1/2 in phosphorylation and regulation of both cytoplasmic and nucleus targets. Numerous neurons were immunostained for ERK1/2 in Purkinje's layer, lateral reticular nucleus, some nuclei of reticular formation, raphe nuclei, nuclei related with visceral sensation, some nuclei in hypothalamus and preoptic area, amygdala, hippocampal formation, part of isocortex.
磷酸化ERK1/2在浦氏细胞层(Purkinje'slayer),外侧网状核,网状结构部分核团,中缝核群,内脏感觉有关核团,下丘脑和视前区部分核团,杏仁核,海马结构和部分同型皮质中标记数目较大的神经元。

It took Cockcroft and Walton five years to build a machine that worked. Finally, in April 1932, they had a machine that produced a steady stream of hydrogen nuclei with an energy of about half a million volts. They were carefully measuring the quality of the stream, in no hurry to begin doing nuclear experiments. On the morning of April 13, Rutherford came into their room, saw what they were doing, and lost his temper. He told them to stop wasting their time and do some science. The next day, Cockcroft was occupied with other business. Walton was alone in the laboratory, ready to do the first experiment, using his hydrogen nuclei to bombard a target made of the light metal lithium. The result was spectacular. The lithium nuclei were split in two and fell apart into pairs of helium nuclei.
用了五年时间,考克饶夫和华尔顿建造出了第一台能运行的加速器,最终,在1932年,他们制造出了能够提供稳定氢粒子流的加速器,粒子能量大约为50万伏特,他们并没有急着做核试验,而是精心测量了粒子流的性质,4月13日清晨,卢瑟福来到他们的房间,看到他们还在测量,大发雷霆,告诉他们停止浪费时间,开始科学研究,第二天,考克饶夫就被安排了其他事情,只剩华尔顿一个人在实验室里,准备做第一次实验,用他的氢粒子流轰击用轻质金属锂作的标靶,结果极为壮观,锂原子被分裂成两半形成一对氦原子,氦原子释放出的能量比氢原子注入的多达三十倍!

The evaluation results under 16 different treatments showed that low fertilization treatment, medium fertilization treatment, high fertilization treatment under RW condition, MW with HF, and NW with HF, the growth condition of crop belonged to suitable; the other 11 treatments belonged to moderate or inaptitude.
对试验中16种不同水肥组合处理的评价结论为:丰水下施低、中、高肥,平水高肥和自然降水高肥等5种处理下属适宜;其余11种处理下属中等或不适宜。

In all fertilization treatments, the mean mass diameter of WSAs was larger in 0-10 cm than in 10-20 cm soil layer. Compared with non-fertilization, long-term fertilization increased the MMD of WSAs, and organic manure was superior to chemical fertilizers.
各处理0~10cm土壤水稳性团聚体平均质量直径均大于10~20cm土层;自然土壤的团聚体MMD显著高于同层次耕作土壤,长期施肥处理MMD大于无肥对照,有机物质培肥处理明显高于化肥处理。

Fertilizing date presented obvious effects on root growth and distribution. Fertilization after watering was more primitive to the root in up-soil layers than before watering. Fertilization of Ca-Mg was positive to the increase of root in 5-15cm soil layer, but negative to that in the surface layer. Both fertilization date and Ca-Mg fertilizer affected root vigor obviously.
施肥时期对根系也具有明显的影响,与灌水前施肥相比,灌水后施肥有利于促进根系在上层土壤中的生长和分布;钙镁肥的施用能增加5~15cm土层根重,但对表层根的生长不利,施肥时期和钙镁肥施用与否对根系活力的影响也较大。

This suggests that CaHIRA plays a role in the early embryo development and the late stages. The different expression characters of hira gene in these fish species may be related to the different reproduction models. The research on Drosophila has indicated hira gene related to sperm nucleus decondensation during fertilization. The high expression of hira gene before fertilization is prepared for the sperm nucleus decondensation and the formation of male prenucleus because colored crucian carp is bisexual reproduction. However, the sperm nucleus is not decondensated during the fertilization and is only to activate egg nucleus in gynogenetic gibel carp.
在彩鲫中,从未受精卵到胚胎发育的各个时期均可检测到表达,但表达量发生明显变化,受精后表达量迅速下降,直到原肠胚期表达量有所上升,并一直保持到出苗。hira基因在两亲缘种成熟卵子受精前后表达情况不同,可能与两种鱼不同的生殖方式有关。

与城市用地变化有关的土地利用类型也多分布在金昌、嘉峪关、张掖、武威和酒泉 5个地级市所在地区,表明这些区域的城市化过程相对活跃;3城市用地变化对生态环境影响的空间规律表现为:使生态环境原本较差的地区生态环境质量有所增加,而使生态环境质量较好的地区生态环境质量降低;4城镇用地与工矿用地对区域生态环境的影响表现出与城市用地总体基本一致的规律,但农村居民点则对生态环境正、负两方面影响都较为显著;5 城市用地扩展对区域生态环境的影响也体现出与城市用地总体类似的区域分异特征;而城市用地收缩的影响则与此趋势相反。
