In total 102 strains of acidic phytase producing strains were selected from soil by selective plate containing calcium phytate . among them 32 strains with relatively large clear circle were purified and re - selected by shaking - culturing . after fermented for 5days at 28 c and shaking at 220r / min , the activity of phytase was determined by nh4vo4 - ( nh4 ) 6mo7o24 method at 37 c and ph2 . 5 or ph5 . 5 主要结果如下： 1植酸酶高产菌株的筛选利用植酸钙选择性子板培养基从土样中筛选出102株酸性植酸酶产生菌，从中挑选出透明圈较大的菌株32株，经分离纯化后分别进行摇瓶复筛， 28 、 220r / min发酵5天后，在37 、 ph2 . 5或ph5 . 5条件下用钒钼酸铵法检测其酶活，结果发现有3株菌产酶活性较高且产酶性能较为稳定。
The system is consist of the main data processing board which is based onthe fpga device and fast ethernet phyceiver rtl8201l and a - law pcm data encoder and decorder chip msm7702 - 3 , and the dial - up and display board which is based on mcu . the main board would carry out the core task of data processing , such as voice data packing and unpacking , the ethernet frame processing , protocol processing , call processing , etc . the dial - up and display board would carry out the task of display the ip address which is input by consumer and status of network during talk period from the main board , and so on . in the paper the system of lan ip telephone and the tcp / ip protocol is introduced firstly , then the fpga device is stated . after that the fpga - based hardware scheme is introduced in detail in chapter four 系统以altera公司的acex1k系列的fpga和快速以太网控制器rtl8201l和语音编解码芯片msm7702 - 3为核心构建了数据处理主板和以单片机为控制器的拨号显示子板组成。数据处理主板的核心任务，包括语音数据处理、以太网帧处理、协议处理、呼叫处理等。拨号显示子板则完成通话前的显示用户所拨过的ip地址，通话期间网络状态的显示等等。
