介绍了用超临界流体膨胀减压过程制备水溶性药物超细微粒的基本原理、工艺流程、技术特点、研究现状和主要研究结果，并展望了其发展前景。

Intracranial purification can vibrate the air to massage tissue inside the ear by mild pressure generated from burning eye candles and its movement.At the same time, plant esscnce in eye candles will cnter the ear slowly. Expcllant massage can help detoxicate, relax, and relicve headaches, It's especially suitable for white-collar workers.

颅内净化是通过耳烛燃烧的产生的轻微压力及火焰的移动，使空气产生振动，来达到按摩耳朵内部组织，同时使耳烛里含有植物精油慢慢地进入耳内，在通过排毒手法来达到排毒、放松、减压、缓解头痛，所以它对于脑部工作者特别有疗效。

During the operation the tumor was intracapsularly decompressed with the diathermy loop by piecemeal.

用电切环内减压法治疗98例大型脑膜瘤患者。

Methods; 45 patients with pancreatic cancer were treated with HIFU for 262 person-times.Before treating,these patients have first taken a Chinese herbal acting as strengthening the body resistance to eliminate pathogenic factors,reliving the depressed liver,sooting the liver and regulating the circulation of qi,promoting digestion and digestant for 3～4 days.In 262 person-times,74 person-times were adopted GI decompression,5～10 minutes before operation 26 person-times ware adopted simple fast,6 person-times were additionally taken airless water,and 156 person-times were additionally taken ultrasonic developer-aid for the use of GI examination.

方法； 胰腺癌患者45例，共行HIFU治疗262次，治疗前先服用扶正祛邪、疏肝理气、消食化积的中草药3～4天，采用胃肠减压者74例次，术前单纯禁食者26例次，禁食后术前5～10min加服脱气水者6例次，加服胃肠检查用超声助显剂156例次。

Furthermore, the disproportionation of MPC into DPC under atmospheric-vacuum condition was studied.

此外，本文还考察了常减压条件下MPC的歧化反应。

After the product of the disproportionation under vacuum was treated through washing and vacuum filtering, DPO with content over 98% could be obtained.

减压歧化反应的产品再经过洗涤、抽滤等处理，可以得到含量为98%以上的DPO样品。

The results showed the disproportionation conversion of MPC could increase dramatically under vacuum condition and decrease the time of the reaction obviously at the same time.

实验结果表明，减压有利于提高MPC的转化率，并且可以缩短反应时间。

The Large eddy Simulation is used to simulate the flow field and cavitation on an Orifice Energy dissipator. The characteristics of cavitation was analyzed. The calculated and the measured pressure distribution and the cavitation were in agreement.

采用大涡模拟方法对消能孔板流场及空化现象进行了数值模拟，研究分析了消能孔板空化特性，计算所得的压力分布及空化特性与减压模型实验结果进行了比较，二者符合良好。

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

另一方面，更重要的是由于城市住房是一种异质性产品。

Climate histogram is the fall that collects place measure calm value, cent serves as cross axle for a few equal interval, the area that the frequency that the value appears according to place is accumulated and becomes will be determined inside each interval, discharge the graph that rise with post, also be called histogram.

气候直方图是将所收集的降水量测定值，分为几个相等的区间作为横轴，并将各区间内所测定值依所出现的次数累积而成的面积，用柱子排起来的图形，也叫做柱状图。
