压下的

Mainly divided into three parts: 1 delayed sound Pedal : Are British horse (John Broadwood block 1783), usually under the piano is invented the right medial step by step, when delay sound pressure nowadays, usually in the string is Damper immediately lift.

主要分为三个部分： 1 延音踏板：是英国人布劳马于1783年发明，通常是钢琴下最右内侧的踏板，当延音踏板被压时下，平时压在弦上的制音器立即扬起。

During operation, the positive rate of patients with increased IMP was significant higher than that of patients without pressure imcreasing(P.01).［Conclusion］The "piston effect" could lead to increased IMP during OIMN of fresh femoral fractures. The increased IMP is an important factor leading to marrow fat intravasation.

结论］股骨骨折早期开放式髓内钉内固定手术中在一定条件下产生的"活塞效应"可使髓内压升高；髓内压升高是股骨骨折早期开放式髓内钉内固定术中导致骨髓脂肪入侵的重要因素。

Due to the modulation of the piezoelectricity, a hole well is formed.

Some meaningful conclusions had been made: 1. In the test, a form of subsurface crack is relative to the sclerometer's shape, when the top of the sclerometer is sharper the crack is easier form.

在该划痕试验中，亚表面裂纹与压头本身的形状有关；当压头顶部较尖锐时，在划痕深度一定的条件下，更容易产生裂纹； 2。

The results of appraisingwith the water parameters showed that all clones had the abilities toincrease osmotic adjustment and turgor maintain during water stress.

根据6项水分参数对无性系渗透调节和维持膨压能力综合评价结果表明，在水分胁迫条件下，各无性系均有一定的提高渗透调节和维持膨压的能力。

A w is the ratio of water vapour pressure of food to that of pure water at the same temperature.

a w指相同温度下，食品的水蒸汽压P和纯水的蒸汽压P0之比。

Three linearity test samples or six circulars test samples (may by revolve compaction machine, librate and press machine, the Marshall meter, or path take the mold intrinsic controllable high temperature which core obtains) puts in specially makes, are dry or immerse the environment mean test.

三个条形试件或六个圆形试件（可由旋转压实机、振动压实机、马歇尔仪、或道路取芯获得）放入特制的模具内在可控的高温、干燥或浸水环境下作测试。

In the experimental process, changes in the samples were observed and photographically recorded using microscope, fluorescence spectrum, Raman spectrum and infrared absorption spectrum of the reacting systems were also determined in situ under high pressure.

为验证这一观点，本论文以金刚石压腔装置为手段，开展了地幔温压条件下(直到地球内部200km的深度)含碳物质与水反应生烃的模拟实验研究。

After annealing in nitrogen at 500 ℃ with the holding time of 30 min, the hardness of the less pure powders decrease by about 30%, while that of high purity powder under the same condition is unconspicuous.

较低纯度铁粉的压坯在500℃氮气中退火30 min，硬度迅速降低30%；而相同条件下高纯铁粉的压坯表面硬度基本不变。

Methods: 7 calf lumbar spine specimens (T13~S2) were biomechanically tested under pure moment of 10Nm loading with Tenor pedicle screw system as the fixation device. Range of motion and intradiscal pressure were measured in all unfused segments and compared among the control group, the single-segment-fixed group (L45) and the double-segment-fixed group (L3~L5), and the correlation analysis and comparison between the increments of kinematic index and intradiscal pressure were performed.

取7具小牛腰段脊柱标本(T13~S2)，以Tenor椎弓根螺钉系统作为固定器械，在10Nm纯力矩加载下进行生物力学测定，测定各活动节段的运动范围和椎间盘内压，比较完整对照组、L45单间隙固定组和L3~L5双间隙固定组间上述指标的变化，并对运动学指标和椎间盘内压增量进行相关分析和比较。
