Until.recentl., communicative l.nguage teaching (Cl.) was.the much favored methodol.gy in many As.an countries.s.ch as.s.ngapore, Mal.ys.a, India and Hong Kong. Cl. begun in the l.te 1970's.in Europe and gained momentum in the 1980's.in many Engl.s.-l.arning countries.al. over the worl.. A whol. generation of younger As.ans.in the 1980's.and 1990's.grew up l.arning Engl.s. through the Cl. approach in the cl.s.room. This.paper wil. chart the reas.ns.behind the ris. and fal. of Cl. in s.ngapore and comment on its.motivations.and effects. It wil. al.0} s.are findings.from a s.udy with regards.to teacher attitudes.towards.the us. of various.teaching approaches. The paper wil. concl.de with a dis.ours. on 'As.an Real.ties. where the adoption of l.nguage methodol.gy is.concerned.

Gait anal.s.s.is.a proces. of l.arning the motion of human and animal.by us.ng wearabl. s.ns.r approach and vis.on approach. This.anal.s.s.is.mainl. us.d in medical.and s.orts.fiel. where the s.udy of body parts.is.crucial. 3-s.ace s.ns.r is.a s.ns.r cons.s.s.of accel.rometer, gyros.ope s.ns.r and compas. s.ns.r, buil. in one device. In this.s.udy, 3-s.ace s.ns.r is.us.d to col.ect data of wal.ing and jogging motion, of a tes. s.bject running on a treadmil.. Angul.r vel.city of the tes. s.bject’s.arm and the angl. of s.bject’s.l.aping motion are the two main components.under inves.igation. Data are anal.zed and proces.ed with Principal.of Component Anal.s.s.(PCA) technique. This.method aims.to combine and reduce the number of variabl.s.of the raw data. The Quiver function is.us.d in order to generate feature vectors.for both motions. Furthermore, the output of the proces. was.us.d to create a s.s.em that can recognize human motion on any given data. The s.s.em is.highl. abl. to differentiate both of the motions.

本文先从社会因素对货车设计的影响谈起。再讨论技术和结构方面的动向。作者认为今后货车的发展以节省燃油为主,方法是: 提高柴油机的热效率。目前美国柴油机每马力小时耗油量约为163克,最好的为150克。预期十年内随着现在处于发展阶段的技术完善之后,可望为145克。近期收益将从润滑油等的改进减少摩擦损失和附件驱动损火等和增压中冷中得到。用子午线轮胎特别是后轮用宽断面单胎代替双胎可减少滚动阻力,节油10～20％。用驾驶室顶部导流罩,改进驾驶室的外形等,可减少风阻35％,节油15～17％。所以十年后如发动机节油10％,共可节油达47％。总重36.3吨的汽车列车在水平公路上以88公里/小时车速行驶时,耗油率将为29.5升/百公里。为提高燃油经济性,提高汽车列车组合总重和列车长度是可能的和必要的。

　建立了组织压随中医推拿摆动类手法作用力发生动态变化时的毛细血管 -组织血液动力学模型 ,以此来解释中医推拿摆动类手法的血液动力学机制。血液在毛细血管内作低雷诺数流动 ,血浆渗出毛细血管壁遵循s.arl.ng定律 ,组织压随实测的滚法推拿作用力线性变化。同时考虑了血液表观黏度、血浆蛋白浓度、红细胞压积。数值计算了组织压动态变化时的毛细血管流量、血液表观黏度、渗透率和渗透因子 ,并和静态组织压的相应变量进行比较。结果显示 ,组织压动态变化导致毛细血管血流量有所增大 ,而血液表观黏度将下降 ,定性说明了中医摆动类手法的“活血化瘀”血液动力学机制。
