查询词典 double root

Whenever a batter hits into a double play, the double play is constituted by a sequence of physical events. It does not follow, however, that we could redene "double play" in terms of precise sequences of physical motions. This is so despite the fact that, if a particular physical sequence constitutes a double play, any physically indiscernible sequence would constitute a double play as well. So being a double play "supervenes" on physical sequences.

无论何时，例如在散打中，一个击打得了两分，这个两分击打是被一连串物理事件所构成，它并不由此得到我们可以根据精确的连续的物理运动来重新定义&双分击打&，尽管事实是，如果一个特殊的物理连续构成了双分击打，但任何物理上难以区别的连续运动也会构成双分击打、（所以，是双分击打，附加在物理连续上。

Aqueous extract of cotton has allelopathic effect on Raphanus sativus, Brassica campestris, Lactuca indica, Brassica campestris, Echinochloa crusgall, Setaria viridis and Abutilon theophrasti and its inhibition effect gradually strengthens with increasing concentration. Aqueous extracts from stems, leaves and roots of cotton inhibit or accelerate seed germination and seedling growth, and activity of enzyme of seedling root of cotton. While aqueous extracts from stems and leaves of cotton are 0.02 gmL^(-1), root length, shoot length, lateral root number and dry weight of cotton respectively increase by 10.3%, 3.1%, 22.9% and 2.4% over the control. The above mentioned indexes are lower than the control by 34.4%, 39.2%, 40.6% and 19.0% respectively as the aqueous extracts are 0.1 gmL^(-1). At the same time, root activity and SOD activity decrease by 38.2% and 36.7%, while POD activity and MDA content increase by 52.3% and 36.5%. Growth indexes of plant receptors increase at low concentrations but decrease at high concentrations of aqueous extracts. The allelopathic effect of aqueous extract of stems and leaves is stronger than that of root.

结果表明：棉花植株水浸提液对萝卜、白菜、莴苣、油菜、稗草、狗尾草、苘麻均具有化感效应，随着作用浓度增加，抑制效应逐渐加强；棉花茎叶和根系水浸提液对棉花种子萌发、幼苗生长、幼苗根系活力、根系酶活性有抑制或促进作用，当茎叶浸提液浓度为0.02 gmL^(-1)时，棉花根长、苗高、侧根数、干重分别比对照增加10.3%、3.1%、22.9%和2.4%，当浓度为0.1 gmL^(-1)时，上述指标与对照相比分别降低34.4%、39.2%、40.6%和19.0%，而根系活力、SOD活性比对照降低38.2%、36.7%，POD活性、MDA含量较对照增加52.3%和36.5%，不同浓度棉花植株水浸提液对棉花生长呈现"低促高抑"的规律，且茎叶浸提液作用效应大于根系浸提液。

Six days after inoculation, the cucumber root tip was slightly swollen and symmetrical root-knots were observed at the meristematic and elongation zones. Giant cells were differentiated by previous cambium cells in the center of the root; 10days after inoculation, symmetrical and secondary root-knots were observed at the root hair and upper zones. Vessels were separated by giant cells, around which protoxylem vessels were observed; l6days after inoculation, hypo-vascular tissue appeared earlier than normal; 20-30 days after inoculation, the vertical arrangement of vessels was disordered, shape was distorted and a new vascular tissue appeared in the cortex.

The author thinks that the main mind problems in the process of research are the followings: one is to tail after the western psychological mainstream and despising transpersonal psychology, the root of which is inferiority; one is to comply with the obsolete so-called scientific methods inflexibly, the root of which is timidity; one is to be wild about introducing our culture to the west without in-depth research , the root of which is speculation; one is to be deliberately mystifying, such as one-sided emphasis on "insight" and unspeakable, the root of which is conceit; one is to try to create our local psychology impatiently but being restricted to a designated area, the root of which is anxiety.

我认为中国的心理学家在研究的心态中存在的问题主要有：追随西方心理学"主流"，鄙视超个人心理学，心态的根源是自卑。严格依从旧的"科学"方法，心态的根源是胆怯。热衷向西方人介绍，但是不深入研究，心态的根源是投机。故做玄虚，片面强调"悟"、"不可言说"等，心态的根源是自负。急切于建立本土心理学，但是画地为牢，心态的根源是焦虑。

Result These difficult root canals caused by broken instruments, luting cement and resinifying agent in canals, root canal calcification and root canal perforation were managed with the success rate of 82.35%, 82.14％, 76.32％and 100.00％ respectively;the incidence of root canal perforation in severe curved root canals was 35.14％during the course of the treatment.

Although both of FDRMADS7 and FDRMADS8 wereexpressed in the root, they have different expression pattern.The transcripts of FDRMADS7 weredetected throughout the root,especially the expression in the root meristem was the highest.However,the expression of FDRMADS8 was mainly localized in elongation and mature rigion.No apparent expression signal was detected in the root cap, root meristem and pericycle cells.

虽然FDRMADS7和FDRMADS8都在根中表达，但它们在根中的表达模式也不相同：FDRMADS7在根中到处表达，尤以生长点处表达量最高；而FDRMADS8在伸长区和根毛区的皮层中有大量表达，在根冠，根尖分生区和根毛区的中柱鞘细胞中却无明显表达，暗示它们在根中行使的功能也不相同。

According to the root type division the Chinese Dwarf cherry belongs to the inductive type of root primitive body,From above several aspects we can see that the mechanism of soft-wood cutting is : Under the condition of without root primordium ,the root primordium appear from cambium by using rooting accelerator under the condition of well temperature ,humidity ,and light, then the root primordium breaks through the cerebral cortex, finally extends to outside .

从以上几个方面我们可以看出，欧李嫩枝扦插生根繁殖的机理为：欧李嫩枝在无根原体存在的情况下，经过生根剂的处理在合理的温度、湿度及光照条件下，由其形成层部位产生根原体，随后根原体突破皮层，伸向外部。
