The authors used coupling phototube convert the voltage of reflector voltages of klystron linearly to lower voltage and converted the lower voltages of standing wave measuring line and crystal detector inputting power linearly to higher voltages by operation amplifier. Then inputted these voltages to computer by analog-to-digital card and plotted the graphs of working characteristics of reflecting klystron with software.

利用光电耦合器将速调管反射极高电压线性转换为低电压，同时将驻波测量线测得电场强度的电压值和晶体检波器所测得的反射式速调管输出功率的电压值通过运算放大器线性放大，然后经过模数转换卡采集到微机中，利用软件绘制出速调管的工作特性曲线。

Methods Proteins and peptides in CSF were separated by two-dimensional gel electrophoresis（2DE） and ultra-performance liquid chromatographer and identified by matrix assisted laser desorption ionization time of flight mass spectrometry（MALDI-TOF-MS） and electrospray ionization to study differential proteomic expression in the cerebrospinal fluid between patients with Demy- elinative disease and with other neurological diseases.

方法以中枢神经系统脱髓鞘疾病患者的脑脊液为研究对象，分别采用固相pH梯度双向凝胶电泳分离总蛋白质，凝胶经银染显色后，用图像分析软件进行比较分析、识别差异表达的蛋白质，离线应用基质辅助激光解析电离飞行时间质谱得到相应的肽指纹图谱；同时用超高压液相色谱分离酶解肽段，在线采用电喷雾四极杆飞行时间质谱鉴定肽段氨基酸序列；搜索数据库鉴定部分蛋白质。

There are nine bivalents in pollen mother cells at late diplotene or early diakinesis, and the homologous chromosomes essentially arrange on the equatorial plate at late metaphase Ⅰor early anaphase Ⅰ, then the two homologous chromosomes of each bivalent separate from each other and move to two opposite poles drawn by spindle fibers.

在减数分裂双线期末或终变期初，可以观察到9个二价体，在中期I末至后期I初，同源染色体基本排列在赤道板上，然后在纺锤丝的牵引下二价体的两条同源染色体分开，分别移向两极，每一极有9条染色体，从而确认该属植物的染色体基数为x=9。

In one of the four cases, the dipole magnetic moment of the wire frame is zero.
