查询词典 km

Because of different views on this method in China,it has been revised and refined by many researchers since it was brought in,and the statistical value Km was apt to be replaced by standardized variate Φm.

Both motor car and each trailer of HST were modeled as a multi-rigid-body system with two suspensions, and LVT was modeled as an assembly of track segment elements with 24 degrees of freedom. The vertical vibration matrix equation of the system was established on the basis of the principle of the total potential energy with stationary value in elastic system dynamics and the rule of "set-in-right-position" for formulating system matrixes, and then Wilson-θ numerical integration method was used to solve the problem. The dynamic responses of the system were calculated when the train runs at the speed of 200 km/h. And the effects of vertical stiffness of rail fastener and block pad on vertical vibration responses of the system were investigated.

其原理是：将高速列车的动车和拖车模拟为具有二系悬挂的多刚体系统；将弹性支承块式无碴轨道模拟为具有24个自由度的轨段单元的集合；基于弹性系统动力学总势能不变值原理及形成系统矩阵的"对号入座"法则，建立此系统竖向振动矩阵方程，并采用Wilson-θ数值积分法求解，计算速度为200 km/h时此系统竖向动力响应，研究轨道刚度对此系统竖向振动响应的影响规律。

More importantly, the magnitudes of cocaine-stimulated stereotypy were positively and significantly correlated with the Km increases.

更为重要的是，可卡因刺激引起的刻板行为与Km值的增加呈显著正相关。

The present experiments revealed that the time course of the changes in Km strictly parallels the time course of the increase in stereotypy after cocaine.

当前的实验发现Km变化的时间过程严格平行于给予可卡因后刻板行为增加的时间过程。

Shortly after the 1931 competition, an R engine using a special fuel blend powered the winning Supermarine S.6B aircraft to a new airspeed record of over 400 miles per hour (640 km/h). Continuing through the 1930s, both new and used R engines were used to achieve various land and water speed records by such racing personalities as Sir Henry Segrave, Sir Malcolm Campbell, and his son Donald; the last record was set in 1939.A 1951 R-powered water speed record attempt by Donald Campbell was unsuccessful.

在1931年比赛后不久，一台"R"发动机在使用一种特别的混合燃料做动力的情况下，使得一架获胜的休泼马林公司的S.6B飞机飞出了超过400英里1小时(640 km/h)的新记录，在随后的30年代里，崭新的和使用过的"R"发动机在亨利·西格雷夫，坎贝尔·马尔科姆爵士及他的儿子唐纳德·马尔科姆这些竞赛名人的手中创造了一系列的陆地及水面速度记录，最好记录于1939年创造，1951年唐纳德·马尔科姆尝试刷新R发动机载动的水上速度记录但没有成功。

The system can reliably perform the operations of starting, speed regulating, braking and weakening magneticfield for high speed. The test trolley-bus carrying with passengers has operated 6, 105 km with good results.

把该系统装于无轨电车上，能可靠地进行启动、调速、弱磁高速和制动等操作；载客运行6105 km，效果良好。

The 250,000 square metre stadium is to be built with 36 km of unwrapped steel, with a combined weight of 45,000 tonnes.

250，000平方米体育场将用36 km被解开的钢修造，与联合的重量45，000吨。

On the dawn side of the plasma sheet, the average of Vx and Vz are nearly equal to 0,but the average of Vy is in the order of －10 km/s.

在黎明侧的等离子体片区， Vx和Vz的平均值约为0，但Vy的平均值的量级为-10 km/s。

The crystallization temperature and pressure of clinopyroxene phenocrysts from the ankaramite and basalt were estimated on the basis of the clinopyroxene-melt equilibrium principle: 1345～1366℃ and 1.75～2.05Gpa for ankaramite, with average geothermal gradient of 20-24℃/km, suggesting anomalous heat or geothermal gradient in this region may be one of the key reasons to produce the porphyry copper deposits in the region. In contrast, those in the basalts fomed under a relatively low crystallization temperature (1129～1191℃), and the pressure (1.19～1.60Gpa) and depth (39～53km), suggesting that the basalt formed under a condition of lower temperature and pressure.

根据单斜辉石-熔体平衡原理计算了富辉橄玄岩和玄武岩中斑晶相辉石形成的温度和压力，前者变化范围主要集中在1345～1366℃和1.75～2.05GPa，其深度相当于58－67km，平均的地温梯度大约20～24℃/km，说明该区具有异常的热或地温梯度，这可能是导致本区斑岩铜矿形成的主要原因之一；后者的温度和压力都相对较低，分别为1129～1191℃和1.19～1.60Gpa，而相应的深度为39～53km，暗示着玄武岩是在相对低温低压的环境中形成的演化岩浆。
