收缩

Three main possible mechanisms for such layer-parallel shortening are hydrocarbon generation, transformation from smectite to illite, and lateral compaction, among which the last is considered the most important mechanism in this case.

文中分析了造成体积收缩的3种可能机制：生烃、伊利石化脱水和压实收缩，其中最主要的是压实收缩机制。

Motilin and gastrin induced contraction of isolated gastric smooth muscle cells in a dose-dependent manner.(2) Motilin- and gastrin-induced antral smooth muscle cell contraction was inhibited by antibodies against Gαi-3. Motilin and gastrin caused an increase of Guanosine-5′-(3-［35S］thio)triphosphate(［35S］GTPγS) binding of Gαi-3.(3) Contraction of antral muscle cells induced by motilin and gastrin was inhibited by the phospholipase C inhibitor U-73122 and the IP3 receptor antagonist heparin.

结果显示：(1)胃动素和胃泌素对胃窦平滑肌细胞均有收缩作用；(2) Gαi-3抗体可抑制胃动素和胃泌素加强胃窦平滑肌细胞的收缩，胃动素、胃泌素明显增加Gαi-3抗体与［35S］GTPγS的结合；(3)磷脂酶C抑制剂U-73122、三磷酸肌醇受体拮抗剂肝素可抑制胃动素和胃泌素引起的胃窦平滑肌细胞的收缩。

There was a good correlation between Ptw,AVCtw,MVOtw,PTV,PUV,UntwR and age.2.Assessment of left ventricular twisting and untwisting of DCM patients19 DCM patients(range 18-80 yr,mean age 50.52±17.52 yr,2 females) and 21 age- and sex-matched normal controls(range18-80 yr,mean age 49.05±16.94 yr,5 females) were enrolled into this study.Then DCM patients were divided into two groups:E/A＜2 group and E/A＞2 group.The routine echo showed the left ventricle dilated and EF decreased.The results show that LV rotation degree, rotation velocity at baseline and apex were irregular changeable with the cardiac cycle;the rotation direction was clockwise at the base and counterclockwise at the apex,and are combined to yield a systolic counterclockwise twisting as seen from the apex,but the rotation at the basal and apex were the same direction in some patients.

扩心病患者左室扭转及解旋特征的研究选择扩张型心肌病(Dilated Cardiomyopathy，DCM)组患者19例(男性17例，女性2例，年龄18～82岁，平均50.52±17.52岁)，健康体检者21例(男性16例，女性5例，年龄18～80岁，平均49.05±16.94岁)作为对照组，扩心病患者按照E/A分为E/A＜2、E/A＞2两个亚组，结果显示：常规超声显示DCM组LVDd值增大，EF值减小；DCM患者左室心底部与心尖部心肌旋转角度、旋转速度随心动周期变化曲线明显紊乱；与正常组比较，DCM患者左室整体扭转角度和速度分别为(6.49±1.82)°、(67.84±15.60)°/s，较正常人显著减低P＜0.01左室舒张末及收缩末扭转角度DCM患者较正常人显著减低(P＜0.01，左室舒张末及收缩末时间在DCM-E/A＞2组较正常人及DCM-E/A＜2组显著缩短P＜0.01DCM患者左室解旋速度较正常人亦显著减低(P＜0.01，左室功能轻中度减低(DCM-E/A＜2)患者解旋率[(0.29±0.07)%]较正常人[(0.42±0.11)%]明显减低，但当左室功能重度减低(DCM-E/A＞2)时左室解旋率[(0.63±0.35)%]较正常人反而增加；左室整体扭转角度、舒张末扭转角度、收缩末扭转角度、解旋与左室射血分数未见明显相关性。3。

Trial in vitro made clear that it could remarkably increase the contractile of sphincter urethrae , inhibite the urinary bladder smooth muscle contraction and lower the baseline; when the mixture of Suo Quan Gu Niao was 25mg /ml, it could inhibit the urinary bladder strip contraction induced by KCL,too.

离体实验发现，缩泉固尿合剂在25mg/ml时能显著增强家兔尿道括约肌收缩力，并能抑制膀胱平滑肌的自动节律性收缩，同时可使平滑肌松弛，基础张力降低；对KCL引起的离体膀胱平滑肌的收缩具有一定的抑制作用。

As the temperature of rat aorta was raised, the vasoconstrictive force and vasoconstrictive speed increased, and the effects of norepinephrine on vasculature were raised. The results suggest that the constant X1 for vasoconstrictive force is a factor sensitive to temperature.

认为NE引起的血管收缩张力的大小，显然也处于温度的影响之下；随着温度的升高，血管收缩张力变大，收缩速率变快，NE对血管的作用效力增强；且张力因子X1是温度敏感因子。

Results AE from CM had vasodilating effect on the contracti on of mesentery blood capillary in guinea pigs and the contraction of rat thoracic aortic ring induced by l0μmol/L phenylephrine, even under the condition of pre-treating with glibenclamide (1μmol/L) or propranolol (3μmol/L). When the endothelium of the rat thoracic aortic ring was removed, AE from CM had not vasodilating effect hut constrictive effect. AE from CM could also increase the contents of NO, NOS and cNOS in the aortic tissue and had no obvious effect on the NO content in plasma and iNOS in aortic tissue of rats.

结果 桑白皮丙酮提取物有抑制去甲肾上腺素收缩豚鼠肠系膜微血管的作用，抑制苯肾上腺素(10μmol/L)收缩离体大鼠胸主动脉环的作用，预加优降糖或普蔡洛尔(3μmol／L)后仍然有松弛作用；大鼠胸主动脉环去内皮后药物无松弛作用，反而起收缩作用；显著升高血管的NO和NOS、cNOS含量，对大鼠血浆的NO和血管iNOS的含量影响不大。

One that constricts , as a muscle that contracts or compresses a part or organ of the body .

收缩肌：收缩性事物，如收缩或压迫身体某部分或某器官的肌肉

Our experiment showed that addition of benzydamine induced vasorelaxation in the denuded aorta precontracted with KCl in the normal krebs.

实验结果亦显示，benzydamine能抑制高钾所引起的收缩作用，并且藉由在无钙之Krebs溶液中，经benzydamine前处理的血管给予高钾刺激之后，再给予钙离子刺激血管收缩，发现其能抑制外钙内流所造成的血管收缩作用。

Shrinkage occurs in two parts - as metal superheats above the melting point and has losses, causing shrinkage, followed by further shrinkage during solification.

收缩发生在两个过程中，温度高于熔点的金属冷却时产生收缩，随后在凝固过程中进一步收缩。

The experiment of the auxiliary heated arc plasma generator shows that thekey arc root has contraction under the condition of having magnetic field when thekey arc root is at the edge of the cathode surface.

在辅助加热电弧等离子体发生器的实验中看到：在有外磁场的情况下，主弧弧根在阴极边缘时，弧根有收缩的迹象，而当主弧弧根在阴极中心附近时，观察不到明显的弧根收缩迹象，并拍摄到有双弧柱的图片；当关掉磁场和弧电流〓时，主弧在阴极和阳极之间稳定的燃烧，主弧弧根稳定在阴极中心附近的一点上，而且弧根没有收缩的迹象，主弧弧根亮区的直径约为6.8毫米，与弧柱段的亮区直径相差无几；因而从实验结果分析可以看出，阴极表面温度的升高，能使主弧弧根直径增大：另一方面，由于主弧弧根直径的增大(即也意味着主弧弧根截面积的增大)，因而使电弧通过主弧弧根传入阴极表面的有效比热流降低，从而减少了阴极烧损。

Means the parent directory, so this command means to execute "toolchain.sh," which is in the current directory.

代表父目录，所以这个命令就是执行当前目录下的"toolchain.sh"。

Yes,In fact,I'm on our city ream.

是的。事实上我是我们市队的。
