After comparing nonlinear simulation with linear, the results indicate that: Weak nonlinearity has definite and apparent influence on the distribution of acoustic fields and focused gain of array, which cause the distribution of waveform is closer to the array and the focused gain deteriorate ; the strong nonlinearity have a strong waveform aberration, because the other waves of non-fundamental frequency appear . No evident distinction is found in the effects between the oblique propagation and the vertical propagation, though less focused gain and influence caused by strong nonlinear produced by the acoustic diffraction which results in more attenuation in terms of oblique propagation.

将线性条件下的模拟结果与非线性条件下的模拟结果进行比较发现：弱非线性会对声场的分布和阵列聚焦增益产生一定的影响，使得声场分布波形比线性条件下的更加靠近阵列，聚焦效果变差；强非线性会使波形发生更严重畸变，这是由于产生了基频以外的其他频率声波引起的；非线性对斜向传播时声场分布的影响与垂直传播时的影响效果基本相同，但由于斜向辐射时的声波衍射造成的衰减要大于垂直辐射时的，因此聚焦增益和强非线性的影响都将小于垂直辐射时的情况。

Results: Before the fixed bridge was applied, under vertical load, the high-stress region was near around the apical of periodontal ligament with mainly compressive stresses. Under oblique load, the high-stress region was near around the cervical of periodontal ligament with both tensile and compressive stresses. After the fixed prosthodontics, stress and strain distributions were similar with that when the fixed bridge was not applied. But the maximum stress, strain and displacement increased apparently. The stresses in exterior surface of periodontal ligament were larger than that of interior surface; this character of periodontal ligament under vertical load was more obvious than that under oblique load.

结果：固定桥修复前，垂直载荷下，基牙牙周膜的应力以压应力为主，应力集中在根尖；斜向载荷下，基牙牙周膜的应力主要是拉应力和压应力，应力集中在唇、舌颈缘；固定桥修复后，基牙牙周膜的应力和应变分布规律与修复前相似，但最大应力、应变值都明显增大；牙周膜内表面的应力大于牙周膜外表面；垂直载荷时，牙周膜内、外表面的应力差异更为显著。

The former formed a kind of KR cyst, while the later formed a kind of NKR cyst. All the kinetosomes, ciliary shafts and microtubules were resorbed in the former, meanwhile, the cell lost most water and cell volume decreased distinctly. In the later, only part of kinetosomes and part of microtubules were resorbed. Cell lost water slightly and volume decreased slightly.

The results indicate that the free radical activity in kidney tissue increases significantly after exercise. As for dynamic changes of LPO, SOD and GSH-Px index based on four time tests, endurance exercise may increase the antioxidative enzyme activity in Kidney tissue, and as a result, it scavenges much more free radical resulting from exercise and enhances the ability for anti-free radical.

大鼠肾脏组织在运动结束后即刻自由基作用明显加强，从其在运动结束后4次测得肾脏组织LPO、SOD、GSH-Px和尿TP排出率指标所形成的动态变化看，耐久性运动可以提高大鼠肾脏组织抗氧化酶活性，从而清除运动时产生的大量自由基，提高大鼠肾脏组织对抗自由基的能力。

The process includes the following steps: dissolving bromine in halogenated hydrocarbon, dropping the bromine solution into reactant system comprising pentabromo toluene, halogenated hydrocarbon, free radical initiator and hydrogen peroxide at 50-65 deg.c, and heating to 60-78 deg.c for reflux reaction until the reactant system becomes transparent; filtering the resultant to obtain solid product, washing with carbon tetrachloride and water separately and vacuum drying to obtain pentabromo benzyl bromide.

具体步骤为：将五溴甲苯、卤代烃、自由基引发剂和过氧化氢组成的反应体系加入到三颈瓶中，将0.07～0.1mol的溴溶于50ml卤代烃配成溶液，在50-65℃温度下滴加到反应体系中，滴加时间为50-70分钟，然后升温至60-78℃温度下回流反应，至反应体系逐渐变透明，且不再产生气泡时，将所得产物过滤，得到固体产物，分别用CCl 4 和水洗涤，真空干燥，即得到五溴苄基溴；其中，五溴甲苯与溴的摩尔比为1∶0.7-1∶1.0，溴与过氧化氢的摩尔比为1∶1.0-1∶1.4，自由基引发剂加入量为五溴甲苯重量的1-10％，卤代烃的加入量为反应体系体积的40％-100％，所用溶剂可以直接进行下一批反应，不需要更换溶剂或蒸馏提纯。

The result indicated that MgO and α- methacrylic acid can together thicken epoxy, and the speed of thickening epoxy become quickly with the increasing content of MgO; when the ratio of MgO and α- methacrylic acid is 3:1, thickening epoxy have a better effect; the thickening mechanism: the terminal corboxyl group of α- methacrylic acid react with MgO, and it accompany with large numbers of heat, the heat can accelerate the reaction between the terminal corboxyl group with the secondary hydroxyl groups of epoxy, intermolecular hydrogen bonding which the water of above-mentioned formation result in and complex compound which format the metal atoms and carbonyl group complexing collective increase the viscosity of epoxy resin.

The protein interaction domains was delineated at the N-terminal 50-amino-acid fragment of HCV core protein and the C-terminus of p53. Confocal analysis also revealed that these two proteins colocalize in subnuclear granules and peri-nuclear region. Transfection experiments using a p53-responsive reporter plasmid in HuH-7, Hep3B, HepG2 and H1299 demostrated that full-length HCV core protein could elicit a positive or negative effect on the p53-mediated transcriptional activation depending on the concentration of the HCV core protein.
