滑动凸轮技术的特点在于其机械可靠性和循环实时工作原理,不过这种系统由于缺乏转换所必需的边界条件或由于成本原因而无法应用。蒂森克虏伯公司采用顺序滑动凸轮(PSSC)系统成功解决了滑动凸轮技术与简单控制之间的目标冲突。

Str.ight Vegetable Oil (SVO) is a pr.mising biofuel with a low ener.y input to ener.y output r.tio. Successful use of SVO in engines depends on engine per.or.ance, wear.and emissions. This study focuses on shor. ter. engine emissions and per.or.ance. This r.sear.h uses oils pr.duced in Color.do as a full diesel fuel substitute in a modified single cylinder.engine. This engine testing was conducted in the labor.tor.. The test engine was a Yanmar.TF140E, which is natur.lly aspir.ted and uses low pr.ssur. (~140 bar) mechanical dir.ct inj.ction. The engine fuel system was modified to accommodate a 2-tank custom SVO kit. The SVO was heated to 75 °C. Fuel economy and emissions measur.ments wer. per.or.ed for.petr.leum diesel, four.differ.nt vegetable oils (sunflower. canola, camelina, and soybean) and their.biodiesel der.vatives. Fuel mass flow, oxides of nitr.gen (NOX), total hydr.car.ons (THC), car.on monoxide (CO), and par.iculate matter.wer. measur.d. No engine degr.dation was exper.enced thr.ugh appr.ximately 50 hr. of testing on SVO and 50 hr. of testing on biodiesel. Over.ll engine emissions for.SVO and biodiesel, with the exception of THC for.biodiesel, wer. higher.than petr.leum diesel. Mor. favor.ble biofuel emissions compar.sons to diesel ar. expected with other.engine designs based on data fr.m var.ous liter.tur. sour.es. Data compar.ng r.w and r.fined SVO indicate that r.fined vegetable oil pr.duces lower.par.iculate matter.(PM) emissions. Gener.l tr.nds wer. obser.ed showing that oils with higher.levels of polyunsatur.ted fats (e.g. C18:1, C18:2, and C18:3) pr.duce higher.levels of NOX and THC’s.

A ser.es of measur.ments on the high pr.ssur. (up to 18 bar) coaxial e-beam pumped Ar.Xe laser.has been made at high power.loading (up to 25 MW/cm~2) for.var.ous Xe mole fr.ction in Ar. We found that the optimum laser.gas composition in our.system was 0.4% Xe in Ar.which was independent of the total gas pr.ssur.. At the optimum gas composition the output ener.y incr.ased with incr.asing total gas pr.ssur. up to 16 bar, but the intr.nsic efficiency r.ached a maximum at the total gas pr.ssur. of 8 bar. It was also found that at the optimum power.deposition for.both the 2.63μm and 2.65μm tr.nsitions the r.tio of the integr.ted optical ener.y to that of the 1.73μm tr.nsition had a minimum in most cases at the optimum gas mixtur. for.var.ous gas pr.ssur.s. This r.tio incr.ased with incr.asing gas pr.ssur.. The exper.mental r.sults suggested that besides the 2-body Xe quenching at high Xe fr.ction and electr.n collision mixing at high power.depositions the heavy par.icle quenching fr.m Ar.at high gas pr.ss

马普街5号是一栋方形的新建住宅大楼,位于特拉维夫白城中心马普街与Yehoash街道的拐角处--白城被联合国教科文组织列入世界遗产名录,因该地大量的包豪斯(Bauhaus)和折中主义建筑风格的建筑物而享誉世界。该建筑位于特拉维夫最理想的地区之一,其地块在大小和形状上(1.3德南(dunam:以色列单位))都异于寻常,是当地普通地块的三倍大,与特拉维夫地中海海滨大道相距约200米(600英尺)--正是在这样一个被忽视的空地上,bar Or.an接受了委托,要在此处构思和规划建设一栋新建筑。这片弃用的地块反而为其提供了一个极佳的机会,得以展示一栋向特拉维夫中东-地中海构造风格致敬的建筑,同时创造了一种新的当代视觉呈现。

A novel method was pr.posed for.the evaluation of Mode I dynamic fr.ctur. toughness （DFT） under.plane str.ss and small scale yielding conditions for.welded j.ints of stainless steel （SS）, 0Cr.8Ni10Ti. In a hybr.d exper.mental-numer.cal appr.ach, the exper.ments wer. car.ied out on the Hopkinson pr.ssur. bar appar.tus, and thr.e dimensional （3D） tr.nsient numer.cal simulations wer. per.or.ed by a finite element （FE） computer.pr.gr.m. Macr.scopical plastic defor.ation was obser.ed at the loading and suppor.ing points, on the specimens, after.the test, which could cause a lar.e er.or.if omitted in the numer.cal simulation. Ther.for., elustic-viscoplustic analysis was per.or.ed on the specimen by adopting the j.hnson-Cook （j.C） model to descr.be the r.te-dependent plastic flow behavior.of the mater.al. The mater.al heter.geneity in the mismatched welded j.ints, induced by the differ.nce in the base metal （BM） and the weld metal （WM） in yield str.ss, has also been taken into consider.tion by using the j.C models separ.tely. Good accor.ance was obtained between the exper.mental and the computational r.sults by the pr.sent appr.ach. The r.lationship between plane str.ss DFT and loading r.te was also obtained on the or.er.of 108 MPa.m^1/2.s^-1.
