On the one hand, a particularist view of teaching skills as context-specific responses is liable to give hostages to the fortunes of those who claim that, since the art or craft of teaching rarely if ever involves the application of general rules and principles, it can only be learned via the hands-on school experience which renders college training largely redundant.
一方面,一个particularist鉴于教学技能方面的具体对策,即属给人质的命运,这些谁主张,既然艺术或工艺的教学,如果以往很少涉及的应用一般规则和原则,它只能通过经验教训的手中,对学校的经验,使学院的培训基本上是多余的。

The prepared powders were characterized by XRD, UV-Vis, FTIR, N_2 adsorption, Fluorescence spectroscopy, etc. N-doped TiO_2 evidently shows its absorbance shoulder shift into visible light region. Moreover, N-doping retards the transition of TiO_2 from anatase to rutile type as well as restrains the growth of the crystal size which leads to less decrease of surface area. These characteristics are considered to benefit the photoactivity of TiO_2; When all the samples were applied to the photodecomposition of Methylene Blue under visible light(λ>400 nm), the N-doped TiO_2 show an obvious superiority when compared to the undoped TiO_2, the active hydroxyl groups are found to play a important role in this high photoactivity; When the same experiment was performed under UV light, all the samples show the consistent sequence of photoactivity as in the visible light.
通过UV-Vis、XRD、BET、IR、FL等表征手段测试表明:掺氮不仅使TiO_2的光吸收区域拓展到可见光区,而且有利于延缓TiO_2晶相的转换,从而抑止了高温煅烧下所引起的晶粒增大以及比表面积的降低,且氮源浓度越高,此现象越明显,这些特征都有利于催化剂光催化活性的提高;在主波长大于400nm的可见光催化亚甲基蓝实验当中,掺氮TiO_2的光催化活性明显优越于未掺氮样品,亚甲基蓝在90min内达到88%的脱色率。

For the problem that the suppression of co-channel interference and suppression of noise can't be balanced in signal-to-jamming and noise ratio maximization method for the linear precoding of multiuser multiple-input multiple-output downlink systems, an improved scheme that the term of noise variance is modified as a piecewise linear function is proposed, in which the balance between suppression of co-channel interference and suppression of noise can still be maintained even when the noise variance is a small value through piecewise modifying the term of noise variance, and thus the bit error rate and capacity of the systems are further improved.
针对多用户多输入多输出系统下行链路线性预编码的信干噪比最大化方法中,共信道干扰抑制和噪声抑制不能有效平衡的问题,提出将其中的噪声方差项修正为以噪声方差为变量的分段线性函数的改进方案。该方案通过对噪声方差项的分段修正,在噪声方差的值较小时依然能够保持共信道干扰抑制和噪声抑制间的平衡,从而使系统的误比特率性能和容量得到进一步提高。

Compared with the Epoxy resorcinol-formaldehyde resin pretreatment system and Maleic anhydride pretreatment system developed by Xusigui, the 40% carbolated styrene-butadiene latex system can keep the composite"s properties and reduce the cost of pretreatment and simplify the pretreatment technology; especially to the HST 2073 latex system, the composite"s mechanics properties are improved greatly. Secondly, the composite"s comprehensive properties and interface performance are improved by reinforced with short fiber grafted with rubber in the surface. Thirdly, to simplify the production technology of composite, we add TKM-M and RF-90 as adhesive agent to the composite blended in an internal mixer, so as to the composite can be used to industry widely, then the effect of the amount adhesive agent on the composite"s properties and interface adhesive performance was studied, from the experiments the optimum amount of adhesive agent was deduced.

In this paper, the stress and strain fields of lithosphere in Himalayan Western Syntaxis orogenic belt and its adjacent areas since 10Ma are investigated through using the 3-D finite-element simulation, and deformation and evolution process in former 2Ma are simulated with different rheological parameters and rheological structure. Studies on functions in simulation process of different viscosity parameters, constitutive relation and changes of initial curst thickness show below results:(1) When various viscoelastic models are adopted, the selection of the coefficient of viscosity in the Western Syntaxis area has important influence on the its uplifts and evolutions. The computational results show that the viscosity in the Western Syntaxis area should be smaller than 1023Pa·s;(2) When the elastic model is adopted in relatively rigid Tarim basin, obvious changes are induced to the stress and strain fields of the whole Western Syntaxis area;(3) The existence of mechanical property stable block doesn′t make the propagation of the stress field show obvious decoupling phenomenon.
