The largest baud rate of transfers is 19200bps which means that the converter has practicability . any boat carried facilities with the rs232 serial communicating ports can be connected to the ethernet of the boat carried facilities integrated system by connecting to a switch . the dissertation consists of six chapters 该协议转换器软件采用客户机服务器模式编制，可达到的最大传输波特率为19200bps ，具备实用性，任何具有rs232串行通讯口的船载设备都可以通过该协议转换器与交换机相联接入船载设备集成系统以太网络。
The complete elimination of aflatoxin in agricultural products is extremely unlikely . they are stable in foods and resistant to degradation under normal cooking procedures . thus , recommendation from joint expert committee on food additives ( jecfa ) is that the amounts present in crops and foods should be reduced to the lowest levels that are technologically achievable 由于食物中的黄曲霉毒素呈稳定状态，在一般烹调过程中不易分解，因此要完全清除农产品中的黄曲霉毒素，是近乎不可能的，连食物添加剂专家委员会( jecfa )也仅建议人们利用可达到的科学技术将农作物和食物中的黄曲霉毒素含量减至最少。
In order to obtain the maximum conversion efficiency we always hope the pump source is operated at the maximum level , thus to raise the input pump energy , we have to apply the galilean telescope to input the pump beam , but it will lead to the bad pump beam quality and the large output beam linewidth 为了获得最大转换效率总希望使泵浦源运转在可达到的最高水平，因此不得不采用伽利略压缩望远镜输人泵浦光以提高输人泵浦光的能量，但是这同时使泵浦光质量变坏，使得输出线宽变大。
