加压力于

Experimental investigation indicates that shock wave velocity and shock wave pressure of beginning which were produced with aluminize RHTL were smaller than that of insensitive RDX in steel plate, however, attenuating velocity of shock wave velocity and shock wave pressure which were produced under contact explosion with aluminize RHTL were quciker than that of insensitive RDX in steel plate, when steel- plate had been separately operated under contact explosion with insensitive RDX and aluminize RHTL, and shock wave press had changed suddenly in the interface between steel and aluminum, In the circumstances, the shock wave velocity had ascended suddenly and shock wave pressure had descended suddenly.

实验研究表明：RHTL炸药爆炸加载钢板下，介质中的冲击波初始速度和初始压力相对RDX较小，衰减相对较快；钝化RDX和含铝炸药RHTL分别作用于钢铝复合板时，在分界面处冲击波速度和压力都发生突越，冲击波速度突跃，冲击波压力突降。

MethodsTraditional gradient force, gradient plus pressure force and gradient vector flow force were used in active contour models to segment malleus, incus, eardrum and some shared surface images. The segmentation results were compared. ResultsBoth the gradient force and the GVF force resulted in satisfactory results when the initial contours were close to the boundary.

将传统的梯度外力、梯度加压力及梯度矢量流外力应用于主动轮廓模型，分别对砧骨、锤骨、砧骨和锤骨间的共享狭窄面及鼓膜等图像进行图像分割，比较图像分割的结果，选择收敛速度快、分割结果准确的方法。

Methods A retrospective analysis was carried out in 245 cases with portal hypertension treated with PCDV or PSRS plus PCDV. The diameter, blood flow velocity and blood flow of portal vein, splenic vein and superior mesenteric vein were measured by magnetic resonance angiograph at 1 week preoperatively and at 2 week postoperatively.

We'll practice an asana series that activates the chakras from the root to the crown while chanting bija mantras and focusing on the specific karmic cause that might be contributing to pain and stress in the body emotional dissatisfaction and mental imbalance.

本节课中我们将通过进行一系列自下而上激活身体的轮穴的体位练习，同时吟唱毕加咒语，并凝神于导致身体疼痛和压力、产生不满情绪和心理不平衡的具体的羯磨原因。

To try to limit such complications, David Pilcher, MD, a senior intensive care unit physician at Alfred Hospital in Melbourne, Australia, and colleagues developed a treatment guideline to direct care in the first 72 hours after transplant. On a simple 2-sided sheet of paper, designed to be hung at the bedside and practical enough to be useful to nurses and junior physicians, the algorithm includes direction on hemodynamic care on 1 side and respiratory care on the other.

May 3， 2007－过去的回溯性研究已经证实，接受移植病患其中央静脉压力高或是PaO2/FiO2（动脉氧气分压/吸气氧气浓度）低，在手术后，相较于没有些症状的病患，仍然需要呼吸器辅助、或是早期死亡风险较高根据项发表于国际心脏与肺脏移植学会第27届年会与科学座谈的研究，现在，研究者已经发现在手术后加护时使用一标准治疗流程，可以缩短病患仍然需要呼吸器的时间、且降低发生重移植器官功能不全的机率。

The results of simulation indicated that the new model can be applied toany loading condition, describe phenomena that the Terzaghi consolidation modelcan not, such as the apparent preconsolidation pressures that depend on strain rate, increment in apparent preconsolidation pressures due to creep during sustained loading, and change of porewater pres...

计算与实验结果对比表明，该模型能应用于一维条件下任何加载方式的固结模拟，能描述表观前期固结压力的应变率效应、次固结引起的表观前期固结压力增加、连续加载下超静孔隙水压的增长规律等一些已被实验广泛证实且不能被太沙基固结理论反映的现象。

The GVF force does better than the other two forces in the segmentation of complex images with concaves. The gradient plus pressure force does better in preventing the model from crossing the slim images.［KEY WORDS］ image segmentation; active contour model; GVF; open contour model

对于简单的图像，梯度外力和梯度矢量流外力均能得到较好的分割结果；对于较复杂及边界凹陷的图像，梯度矢量流外力的分割效果明显好于其他外力；对于纤细图像应用梯度加压力的外力更容易控制模型越界的现象。
