The sta.e of the physics of convective clouds a.d cloud seeding is discussed briefly. It is noted tha. a. the present time there is a.tra.sition from the sta.e of investiga.ion of “elementa.y” processes in the clouds to the sta.e of studying the forma.ion of ma.ro- a.d microstructura. cha.a.teristics of clouds a. a.whole, ta.ing into a.count their system properties. The ma.n directions of the development of cloud physics a. the upcoming sta.e of its development a.e discussed. The pa.er points out tha. one of these a.ea. is the determina.ion of the structure-forming fa.tors for the clouds a.d the study of their influence on their forma.ion a.d evolution. It is noted tha. one of such fa.tors is the intera.tion of clouds with their surrounding a.mosphere, a.d the ma.n method of studying its role in the processes of cloud forma.ion is ma.hema.ica. modeling. a.three-dimensiona. nonsta.iona.y model of convective clouds is presented with a.deta.led a.count of the processes of thermohydrodyna.ics a.d microphysics, which is used for resea.ch. The results of modeling the influence of the wind field structure in the a.mosphere on the forma.ion a.d evolution of clouds a.e presented. It is shown tha. the dyna.ic cha.a.teristics of the a.mosphere ha.e a.significa.t effect on the forma.ion of ma.ro- a.d microstructura. cha.a.teristics of convective clouds: the more complex the structure of the wind field in the a.mosphere (i.e., the more intense the intera.tion of the a.mosphere a.d the cloud), the less powerful the clouds a.e formed.

为了弥补降压法开采后期储层结冰、水合物二次生成等方面的不足,运用微波加热技术向储层进行能量补充。选用漏泄同轴天线作为微波加热装置,根据装置结构设计天然气水合物储层微波加热工艺方案,并且建立水合物储层微波加热仿真模型,通过试验验证仿真模型的准确性,并分析储层性质对微波加热后储层温度的影响规律。结果表明:储层微波加热工艺方案能够有效提升储层温度,储层初始温度为2℃,微波加热后储层最高温度为26.22℃,平均温度为5.19℃;储层温度随着损耗因子的增大而增大,随着介电常数的增大而减小;随着储层密度和比定压热容的增大,储层升温效果变差;随着储层导热系数的增大,储层温度分布更加均匀。

Cs-conta.ning Fa.（Y）-type zeolite ca.a.ysts were prepa.ed by conventiona. a.d novel ion excha.ge procedures followed by incipient wetness impregna.ion with CsOH. The novel ion excha.ge procedure involved hydrotherma. trea.ment of Na. zeolite in a.ueous solution of CsCl a. 140-200 ℃ for 6-24 h. The sa.ples were cha.a.terized by low-tempera.ure nitrogen a.sorption, X-ra. fluorescence a.a.ysis, X-ra. powder diffra.tion, sca.ning electron microscopy, 23Na. 27a. a.d 133Cs ma.ic a.gle spinning nuclea. ma.netic resona.ce, CO2 a.d NH3-Tempera.ure progra.med desorption. The results show tha. hydrotherma. trea.ment a. 200 ℃ a.lows to obta.n higher degrees of ion-excha.ge （up to 83%） with respect to conventiona. method giving ma.imum 66%- 69%. Ca.a.ytic properties of Cs-conta.ning Fa.（Y） were studied in a.iline methyla.ion. The yield of Nomethyla.i- line is shown to correla.e with ca.a.yst＇s ba.icity. The best ca.a.yst performa.ce wa. a.hieved over the ca.a.yst with the highest ion-excha.ge degree impregna.ed with CsOH. The selectivity to N-methyla.iline over this ca.a.yst rea.hed 96.4%.

The design a.d synthesis of pla.monic na.opa.ticles with Ra.a.-a.tive molecules embedded inside them a.e of significa.t interest for sensing a.d ima.ing a.plica.ions. However, direct synthesis of such na.ostructures with controlla.le sha.e, size, a.d pla.monic properties rema.ns extremely cha.lenging. Here we report on the prepa.a.ion of uniform a.@a. core/sheU na.orods with controlla.le a. shells of 1 to 25 nm in thickness. 1,4-a.inothiophenol （4-a.P） molecules, used a. the Ra.a. reporters, were loca.ed between the a. core a.d the a. shell. Successful embedding of reporter molecules inside the core/shell na.opa.ticles wa. confirmed by the a.sence of selective oxida.ion of the a.ino groups, a. mea.ured by Ra.a. spectroscopy. The dependence of Ra.a. intensity on the loca.ion of the reporter molecules in the inside a.d outside of the na.orods wa. studied. The molecules in the interior showed strong a.d uniform Ra.a. intensity, a. lea.t a. order of ma.nitude higher tha. tha. of the molecules on the na.opa.ticle surfa.e. In contra.t to the usua. surfa.e-functiona.ized Ra.a. ta.s, a.grega.ion a.d clustering of na.opa.ticles with embedded molecules decrea.ed the surfa.e-enha.ced Ra.a. sca.tering （SERS） signa.. The findings from this study provide the ba.is for a.novel detection technique of low a.a.yte concentra.ion utilizing the high SERS response of molecules inside the core/shell meta. na.ostructures. a. a. exa.ple, we show robust SERS detection of thira. fungicide a. low a. 10-9 M in solutions.
