The permanent magnets are now mouthed at the exterior of the high-pressure vessel and are no longer in contact with the fluid sample. So this construction of equipment decreases the contamination of each other. Concerning the temperature-control system, the present instrument employs one non-vibrating new technology. In the high pressure systems, a simple and fast high-pressure pump was used to generate hydraulic pressure. This equipment is more easy to control than the literature\'s methods. A digital lock-in amplifier has been used as sinusoidal current function generator and the induced signal detector.

本文对振动丝粘度密度仪在设计方案上进行了大量改进，把磁体从高压容器的内部移植到容器的外部，提高了容器的化学适应性，采用了无振动的恒温新技术，利用了方便快捷的加压方式，极大的方便了实验的进行，减少了实验的工作量，用数字Lock-in锁相放大器作为驱动信号发生器和诱导信号检测器，设备既简单又极大地提高了信号的检测灵敏度。

According to our results, since BaP increased the expression of COX2 and pp38 to reduce the osteoblast differentiation and this phenomenon can reverse by treatment of NS398, but not by treatment of SB203580, suggesting that COX2 activation plays an important role on osteoblast differentiation. Adlay could increase osteoblast differentiation, in co-culture system, and reverse the osteoporotic status in mice, would be a helpful healthy food for enhance osteoblast differentiation. However, about, TBT, we didn't have enough data to support its effect on the differentiation of osteoblast or osteoclast.

所以依据我们所做出的实验结果，虽然苯骈芘会增加COX2和pp38的蛋白表现，但造骨细胞的分化作用仍下降，但若同时添加NS398，则分化能力有恢复现象，这或许可推测说COX2活性在抑制造骨细胞分化上扮演了一个重要角色；薏苡仁在共同细胞培养可以增加造骨细胞的分化作用，且对骨质疏松状态的小鼠具有缓解的能力，因此或许是能促进造骨细胞分化的营养食品；至於三丁基锡由於实验的数据不多，推测其或许并不影响造骨细胞和破骨细胞的分化作用。

2The spine fracture model is a type of instability spine model, it is satisfacted for the test. The new PETF can offer good three-dimensional stabilization to instability fracture spine.it has clinical feasibility . [3]To be a minimally-invasive surgical procedure ,the PETF assistanted microendoscopy can combine decompression and reduction with external fixation for the injuried vertebral colunm without segments fusion.

(1)骨折模型B组是不稳定性骨折模型，满足实验的要求，新型脊柱外固定器能为不稳定性骨折脊柱提供良好的三维稳定，具有临床可行性；(2)轴向压缩实验A组、C组和D组之间的差异均具有显著统计学意义，说明单纯新型脊柱外固定器是一种弹性固定，抗压刚度不够，但新型脊柱外固定器结合PVP术后抗压能力明显，但较正常标本仍有一定的差距，手术后短期内有必要适当腰部支柱保护；(3)新型脊柱外固定器联合MED和PVP术治疗胸腰椎骨折的微创技术能减轻病人的痛苦、达到胸腰椎骨折的治疗目的和效果，并具有非融合性固定的特点，具有较大的临床推广应用价值。

And there are lots of supernormal stimuli; chocolate cake is one.

我们喜欢甜食，是因为它的高能量跟巧克力蛋糕本身无关巧克力蛋糕是种超乎寻常的刺激诺贝尔生物学奖得主丁柏格做过一个有名的海鸥实验他发现海鸥嘴上那个橘色的点如果变大一点或颜色更鲜艳一点小海鸥啄食它时会更用力它对小海鸥而言是个强烈的刺激实验的意义是超乎寻常的刺激像是巧克力蛋糕会改变天性还有很多东西是超乎寻常的刺激有些会引发性感的感觉。

A series of experiments were done to substantiate the feasibility of the different piezoelectric cochlea implants in vitro and in vivo . The unpoled ceramic had no piezoelectric characteristic and no ability to decrease the threshold, while the poled ceramic had obvious piezoelectric effect to recover the hearing. Based on these results, it can be affirmed that the piezoelectric cochlea implant can activate the nerve and decrease the threshold.

本研究通过未极化与极化的高灵敏性压电陶瓷的对比，从体外模拟实验中的声电响应曲线和动物体内植入实验的结果中得到：未极化的压电陶瓷没有压电响应，而极化后的压电陶瓷能够将声音信号转化为电信号，证实了压电陶瓷的压电特性的确可以刺激动物的听神经，从而降低听阈阈值。
