The results show that the amorphous PLGA fiber with porous structure (0.1-1.0 μm) is obtained by diluted solvent spinning method and the mechanical properties is affected by pressure and temperature. Bending strength and shearing strength of the samples increase firstly and then decrease with the increase of molding temperature and pressure. While the molding temperature is 160℃and the pressure is 105MPa, the PLGA materials possess optimal mechanical properties, bending strength, shearing strength and bending modulus 187.3 MPa, 100.0 MPa and 2.5 GPa, respectively. The mild temperature molding PLGA materials are desired to play a grate role in non-bearing internal fixation devices.

Until the third stage, when subtropical high retreats completely from the SCS and the low pressure system over southern China moves southeastward and embeds itself in the low pressure zone over the northern SCS, strong tropical southwesterly flow brings in ample amount of moisture and causes moisture convergence over the southern SCS under the influences of the low pressure zone. Deep convections bloom due to sudden increase of low-level convective instability.

一直到第三个阶段，太平洋副热带高压完全退出南海，而华南低压中心移入南海北部的低压带，与强盛的热带西南气流结合，在南海南部形成强烈的西风与大量的水气集结，低层对流不稳定度快速增加，以致於产生旺盛的对流。

A measuring approach of pressure oscillation has been developed and experiments are conducted in a 10 liter two-dimension air-lift loop reactor. The experimental results show that the local mass transfer parameters have close relationship with the operating conditions, the structure of ALR and the properties of the reaction systems. A series of measurements of pressure pulse indicate that a gas distribution zone exists near the gas sparger, and in this zone the responding signals of pressure pulse are different with the signals measured in other parts of the reactor.
