Controlling organic-inorganic liquid crystal structures to form lamellar mesostructured crystalline silica nanosheets(LCS) was achieved by using the simple cationic surfactant cetyl trimethyl ammonium bromide(CTAB). The organic-inorganic interaction under the condtions of a high surfactant concentration and suitable synthesis temperature played an important role in the construction of mesostructured crystalline silica.

The synthesis of mesoporous zeolite-anchored atomically dispersed metal catalysts(ADCs)is a considerable challenge in chemistry and materials *** we report the synthesis of atomically dispersed cationic nickel-confined mesoporous ZSM-48(ANMZ-48)by in situ hydrothermal reaction employing a designed tri-functional metal complex template,by which the triquaternary ammonium groups in the hydrophilic region direct the formation of ZSM-48 zeolite;the aromatic groups in the hydrophobic tail generate the mesopores through π-π stacking;and the complexes formed by nickel ions coordinated with terpyridyl groups generate atomically dispersed Ni2+confined in zeolite frameworks due to the strong sintering resistance generated by the strong coordination *** ANMZ-48 is consisting of stacking of sheet-like ZSM-48 domains connected by multiply crystal twinning sharing the common(011)plane,generating abundant of imbedded mesopores with the uniform thickness of~2.4 nm and with the width of 10-50 *** excellent catalytic activity and stability of ANMZ-48 were also reflected in the dry reforming of methane(DRM)reaction.

In order to study the responding of different growth state on low temperature in Broccoli (Brassica oleracea var. italica), we took prematurity broccoli hybrid as the objects. It was found that growth state was varied under different sowing time , moreover, stem became wider with the increasing of light density at the same leaf age. Seedling age of responding to low temperature vernalization only when they grew five leaves above and with over 3.03 ±0.07 centimeter stalk width in 'Qingfeng Broccoli 103'. The older leaf age was and the stronger plant was, the more sensitive and the shorter demanded duration time on low temperature was, and the shorter time required when the plants entered into critical period of floral bud differentiation.

某水库库岸滑坡体滑速及涌浪估算

在长期自然营力后,大部分边坡都渐渐趋于稳定。但如果水文地质环境发生变化,稳定状态下的边坡也可能失稳。以水库为例,在正常蓄水运行后,库岸边坡浸水岩土体饱水软化;当水库水位骤降时,来不及排出坡体内部岩土体的一些孔隙水,会产生渗... 详细信息

在长期自然营力后,大部分边坡都渐渐趋于稳定。但如果水文地质环境发生变化,稳定状态下的边坡也可能失稳。以水库为例,在正常蓄水运行后,库岸边坡浸水岩土体饱水软化;当水库水位骤降时,来不及排出坡体内部岩土体的一些孔隙水,会产生渗透作用。这两种情况都增加了库岸失稳破坏的可能性。失稳破坏后形成的滑坡体冲入库区,将严重影响水库大坝安全。计算滑坡体冲入库区的滑速和造成的涌浪高度,评估其对大坝的影响。

“虚者补其母,实者泻其子”治则的发生学原理主要有五行相生规律、虚实补泻理论、经络学说与五腧穴理论、五行五腧穴配属与五行相生的人伦化说理(推理)5个方面。五行相生的人伦化说理(推理)是该治则赖以发生的肯綮所在,它将“母子”双向关系塞到五行相生这一单向不可逆的过程中,从而成为该治则理论诸般混乱的始作俑者。摒弃“母子”双向说理,以“‘我’病及‘我生’”“虚者补‘生我’,实者泻‘我生’”取而代之,还五行相生以单向不可逆性特征,乃该治则理论重建的出路之所在。

[目的]提高中医学术界对“土爰稼穑”中“爰”字解释的准确性,回归经典原旨的解读,进一步深化对“脾为后天之本”理论源流的认识。[方法]从训诂学出发,在分析《尚书·洪范》有关五行特性经文中“曰“”爰“”稼穑”字义的基础上,对五行特性“土爰稼穑”作出新解读。[结果]“爰”字当以“于焉”以及“援引”“引用”为解,其要义有二:其一明示“爰”与“水曰润下,火曰炎上,木曰曲直,金曰从革”之“曰”的区别;其二强调土行特性包罗万象,土固然可以用来“稼穑”,但其用又绝非“稼穑”之一途,土行特性是“稼穑”所难以囊括殆尽的,所以特地冠以“爰”字,以示不得已而勉强援引“稼穑”论说。[结论]《尚书·洪范》之“土爰稼穑”本质上已凸显了土行的重要性,“土生四象”也蕴意其中,或为“土生万物”哲学命题的滥觞。该命题对中医学影响深远,并最终孕育出“脾为后天之本”等重要的经典理论。
