Trichogramma showed high control efficacy on cotton bollworm eggs after three times of release both in the second and in the third generation bollworm periods. The parasitism on the second and third generation bollworm eggs were 66.0%-70.7% and 76.0%-81.2%, respectively, which were significantly higher than that in the control (second generation: 7.0%-12.3%, third generation: 5.2%-7.4%). And the injury rate of cotton buds and bolls in the second and third generation bollworm were 2.2% and 3.1%, respectively, which were significantly lower than that in the control (second generation:8.5%, third generation: 20.9%). In the second generation bollworm period, number of bollworm eggs or larvae in the Trichogramma released cotton field did not differ to that in the chemically controlled field. But in the third generation, there were significantly less bollworm eggs and larvae in the Trichogramma released cotton field. There were more predators in the Trichogramma released cotton field. These results indicated that cotton boll worm in the transgenic insect-resistant cotton field can he effectively controlled by mass-releasing of T.

The analysis of simulation result indicates that the CDMA system has much more superior performance on noise-immune; the continuous processing in the part of signal modulation can not improve the efficiency of spectrum in CDMA system; under the situation , making sure that the proximity of the reliability of information transmission to the unsmoothed system, the power of the transmission can decline to 90.5% of the unsmoothed system, the bandwidth of -50dB will decline to almost one half of the unsmoothed system in spread spectrum and dispread spectrum by using continuous WALSH codes.

仿真及分析结果表明：CDMA系统具有更优越的抗噪声性能；信息调制部分的平滑化处理在CDMA系统中不会改善频谱的利用效率；运用平滑化WALSH码进行扩频和解扩时，在保证信息传输可靠性与非平滑化系统接近的情况下，能够将发射功率降低到非平滑化系统的90.5%，-50dB带宽减小到非平滑化系统的一半左右，这有利于降低对临近频段的干扰，提高频谱的利用效率。

The method involves an iterative procedure, which incrementally flattens a 3D triangular mesh by region growing and obtains a parameterization with free boundary. The result is then converted to a parameterization with regular boundary by conformal mapping. Our method accounts for both the angle and area distortion during parameterization, it yields a parameterization with less global distortion and no triangular flipping.
