你可于5月至6月间,选择节间较短的当年生半木质化枝条,自基部切下作插穗,顶端保留3片至5片小叶,若枝条过长,亦可截去顶梢,扦插介质可用兰花泥。高山腐殖土。蛭石。珍珠岩或黄心土等,厚约15厘米至20厘米,下铺7厘米至8厘米的排水层;把介质喷湿后,将插穗插入基质中,插穗入土深度约为穗长的1/2,家庭少量扦插也可选用大花盆盛装介质代作扦插苗床。插后加盖塑料薄膜保湿,温度控制在25℃至30℃之间,加设荫棚遮挡阳光,或挪放于树荫下,始终保持扦插基质湿润,东鹃约过1个月即可生根,而西鹃则要60天至70天才能生根。9月后可减少遮荫时间,并追施稀薄尿素液一次,浓度约为0.2%,10月下旬即可上盆。

The stude announces that their changeable regular of the center of gravity level speed in supporting phase is falling in tne first cushioning phase. When their center of gravity's vertical lines pass their heels and their knee joints go on extended contraction ,their center of gravity level speed has extended .the reason is that their angles have passed the heels and their swinging legs' kenn joints have swinging the front of their bodies. Its power originates the swinging leg's forward active swinging and the decurtation contraction of hip joints 、ankles of the supporting legs.the swinging leg shows "the calf's active backward swinging"before its landing impact,the skill affects the loss of center of gravity level speed when the swinging leg lands.they enlarge their trunks' forward-landing impact phase ,it can decrease the center of gravity level speed's loss after landing and impel the center of gravity level speed to pass the supporting spot quickly.

两人缓冲阶段身体重心水平速度变化规律是在体前缓冲阶段呈下降趋势;当身体重心垂线超过脚后跟后,在膝关节继续缓冲做退让收缩的情况下身体重心水平速度开始加大,原因是踝关节在最大缓冲时身体重心已移过支撑面及摆动腿膝关节已做体前摆动,主要动力来源于摆动腿的积极前摆和支撑腿髋、踝关节的克制性收缩;在摆动腿下压着地前期是大腿积极下压小腿随大腿的积极下压顺势向前下滑摆,在摆动腿下压着地后期表现出"小腿积极回摆"技术,对减小着地时的水平速度损失、加大向前用力都有积极影响;适当加大摆动下压着地阶段躯干的前倾角度,有利于减少着地时相的速度损失和有利于身体重心较快的移过支撑点;缩小后蹬结束后的后伸动作幅度,有利于减小腾空时间。

The result showed that there had little influence on the growth of Ca-enriched Sp. maxima when adding 0. 6 g/L CaCO3 and harvesting in 24 h in the end of the lag phase. It was also found that the Ca - enriched Sp. maxima had highest organic calcium content, higher total calcium content and higher ratio of organic calcium and total calcium.

8Ps for native and NaBH〓 chemically modified reaction centers, and the transfer process from H〓 to the final electron acceptor Q〓 occurs in about hundreds of picoseconds. On the other hand, the energy transfer from excited B was obviously slowed down in the pheophytin-exchanged RC. By considering the change of free energy of ion pair P〓Phe〓, it could be expected there might exist alternative pathway of charge separation and electron transfer in pigment-exchanged reaction center. In addition, the influence of acid environment on the ultrafast dynamics of reaction center was also experimentally observed, which shows an evident difference from that of in native RC, and further investigation should be carried out to elucidate the origination.

在色素置换后的反应中心中,以B为起点的能量传递较天然RC的情况明显减慢,约在450fs左右,考虑到置换后的反应中心中P的自由能有所提高以及其仍然保持的光化学活性,这一较慢的能量传递也可能预示着还存在着其它的能量传递通道;另外,还对酸性处理的反应中心中的超快光动力学过程进行了尝试性的研究,发现由于色素分子的聚集以及蛋白环境的改变,BChl分子的激发态动力学过程有着明显不同于天然反应中心的情况。
