Essential hypertension caused by neurovascular compression of the left ventrolateral medulla was associated with malbalance of vasomotor center in the dorsal medulla. The possible pathogenesis was the following:① An irritation of the left RVLM by pulsatile compression of an ectatic vessel would increase activity of central sympathetic neuron.② Neurovascular compression at the REZ of the cranial nerves Ⅸ and Ⅹ decreased excitation of parasympathetic nerve.③ Decreased sensitivity of afferent inputs to neuron of nucleus tractus solitarii in the sensory area lead to hyperactivity of central sympathetic nervous system due to pulsatile compression of the left RVLM.④ Neurocompression of the left RVLM and REZ in the left cranial nerves Ⅸ and Ⅹ lead to an overactivity of central renin angiotensin system.

3，结论：左侧延髓腹外侧Ⅸ、Ⅹ颅神经REZ动脉血管压迫所导致的高血压的发生与左侧延髓血管运动中枢对血压的调节失衡有关，其可能机制是：①左侧RVLM在搏动性血管压迫刺激下，中枢交感神经元活性增高；②左侧Ⅸ、Ⅹ颅神经REZ受压导致副交感神经兴奋性降低；③感受区孤束核神经元接受迷走神经传入冲动的敏感性减低，导致中枢交感神经活性增高；④左侧RVLM及Ⅸ、Ⅹ颅神经REZ受压引起中枢RAS活性增加。

According to the neural cable model, this dissertation deduced a stable solution. Based on the lead model, the vibratory equation of electriferous lead in a static magnetic field is set up under the condition of coupling magneto-acoustic field. It is verified that the vibration in bio-tissue is proportional to with the product of the magnitude of the magnetic field, the current amplitude and the sinusoid of angle between them.

根据神经的电缆模型，论文导出直流稳态解；基于导线模型，根据洛仑兹方程和细弦上的波动方程，论文建立了磁声耦合条件下带电导线在磁场中的振动方程，导出生物组织中的振动与磁场的大小、电流的大小和磁场与电流角度的正弦值乘积成正比。

With addition of benzene and under certain current density and temperature, the indirect organic electrosynthesis using lead tetraacetate as media could be carried out in one compartment and no lead metal was deposited on the counter electrode.

在该醋酸电解液中加入一定量的苯，控制一定的电流密度、温度等条件可以阻化铅在对电极上的析出，实现了无隔膜电解槽中四醋酸铅的电解生成，并应用于间接有机电合成。

The restoration of dentition meant not only to fill the missing teeth and increase the efficiency of mastication, but also to maintain the integrity of dentition and the health of residual teeth, especially loosen teeth that could be reserved. Bone resorption might lead to teeth mobility and the change of occlusal pattern and proximal relationship. Also, the endurant threshold to bite force decreased. Occlusal loads within the normal range to loosen teeth would lead to broken down of periodontal tissues.

中文题名PVDF咀嚼力测试仪的研制及松动牙咀嚼生理功能的研究副题名外文题名 The study of masticatory performance of loosen teeth and PVDF-based instrument for dynamic chewing force measurement 论文作者李鸿波导师姚月玲教授学科专业口腔临床医学口腔科学研究领域\研究方向学位级别博士学位授予单位第四军医大学学位授予日期2002 论文页码总数108页关键词牙列缺损松动牙咀嚼力最大〓力馆藏号BSLW /2003 /R783 /9 修复牙列缺损不但要修复缺牙、恢复咀嚼功能，也要维护牙列的完整性、保护余留牙，尤其是可保留的松动牙的健康。

So consequencetly difference in age structure of Engraulis japonicus populations would lead to change its element compositions. Since Engraulis japonicus was one of the most important diet to high trophic fishes such as Scomberomorus niphonius and Trichiurus lepturus, Unbalance of supplying elements of potential diets would directly lead to the facts that some fish species would grow slower and smaller.

因此，鳀鱼种群年龄结构的变化导致了种群元素组成的变化，同时由于鳀鱼是上层鱼类的重要饵料，因此潜在饵料的元素供给失衡，直接导致带鱼等鱼类因鳀鱼资源衰退而生长缓慢，个体瘦小。

Neither team took a lead larger than seven points in the first three quarters, with the Bobcats constantly staying close to the Lakers on big baskets from Stephen Jackson. Nazr Mohammed's fallaway jumper with 1:38 to play trimmed Los Angeles' lead to 93-92, but Pau Gasol responded with a quick hook shot before blocking Jackson's driving layup.

在前三节没有一支球队的领先分数能超过7分，夏洛特山猫凭借斯蒂芬-杰克逊超能力的表现一直紧咬着比分，默罕默德在比赛还剩下1：38的时候后仰跳投命中帮助山猫将比分追至92-93，但是随后保罗-加索尔一记转身勾手命中，回来又封盖了杰克逊的上篮，让湖人继续保持领先。

The rare disperse metal galium and germanium of Fankou Lead Zinc mine mainly exist in sphalerite in the form of isomorphism. How to recovery them is a key subject since Fankou Lead Zinc mine was set up.

凡口铅锌矿稀散金属镓锗主要是以类质同像形式存在于闪锌矿中，如何有效地综合回收镓锗是凡口矿建矿以来研究的主要课题之一。

Therefore, researches to develop new lead-free solders that do not contain lead have been pursued. From these points of view, it is impendency to develop the Wetting Balance Tester, which can measure the surface tension of solder alloy easily.

另外，由于铅有毒，研制无铅钎料就显得非常迫切和重要，其中无铅钎料的表面张力作为钎料的重要物理性能指标之一是非常值得定量研究的，因此研制润湿力测量仪非常必要。

The inspective mode for blood lead of children aged 0～6 years has tremendous effect in reducing lead poisoning and harm to children.

0～6岁儿童血铅监测模式对降低儿童铅中毒，最大限度地减低铅对儿童的危害，有着巨大的干预作用，把0～6岁血铅监测模式纳入儿童保健工作常规，具有有效性、可行性、可持续性，适宜在全国推广。
