RESULTS:①Cytocompatibility of PEG-PLA-PGL membranes with HUVECs: The observation result of phase contrast microscopy showed that, endothelial cells planted on the PEG-PLA-PGL membranes began to attach and stretch after being planted 4-6 hours. Three days later, cells grew in colonies rapidly, after 5 days, colonies began to fuse and seemed like cobble-stone. The cells were shuttle or polygon in shape after passages.

结果：①人脐静脉内皮细胞与聚乙二醇-聚乳酸-聚谷氨酸三嵌段共聚物膜片的细胞相容性：相差显微镜下种植在聚乙二醇-聚乳酸-聚谷氨酸三嵌段共聚物膜片上的细胞4~6 h后即开始贴壁、伸展，3 d后细胞开始呈集落样生长，生长较快，5 d后细胞集落开始融合，呈现特征性的鹅卵石样形态，经多次传代后，细胞呈长梭形或多角形，与对照组相比无明显差异。

Based on the condensability of liquid,the structure used in multi-axis force sensor of underwater robot aimed at balancing hydraulic pressure was investigated and an iteration algorithm used to calculate the pressure difference between in and out of the sensor was put forward,which applied the pressure balance method of film .

Common diaphragm electrolyzer were revamping by activated cathode process and modified diaphragm process.

该故障是由于传感器测量膜片或隔离膜片的弹性模量发生变化而引起的。

Pressure governor valve is the use of a spring-loaded power and pressure balance theory, when the spring-loaded pressure less than atmospheric pressure and the valves closed when the pressure is greater than the spring-loaded rubber tubing stretch when the bottom of compressed air diaphragm, diaphragm the effort to promote diaphragm upward and left vavle seat blow the air flow of gas, this would piston shirking role in the pressure mobile, Selection will be emissions from valve seat, air compressors made by the then air into the gas valves and exhaust emissions is through the mouth into atmospheric air compressors idling.

调压阀的原理是利用了弹簧力与压力相平衡的原理，当弹簧的压力小于气压的时候阀关闭，当压力大于弹簧的弹力时候橡胶调压膜片下方的压缩空气对膜片的用途力，推动膜片向上拱曲离开阀座而使空气流入气腔，此时卸荷活塞在气压用途下移动，将排放阀门推离阀座，于是由空气压缩机充入气腔的空气便通过排放阀和排气口排入大气空气压缩机空转。

The true and false cavities of aortic dissection could be displayed on the SE T1WI,T2WI for the B type in 10 of 12 cases.With SE sequence,the true-false cavities did not be showed but the endomembranous pieces could be seen for A type of 2 cases of aortic dissection.
