The optimum conditions to synthesizeβ-carboxyethyl organogermanium sesquioxide were established through orthogonal test: the time from beginning to adding sodium hypophosphite was 0.5h; the molar ratio of germanium dioxide, hydrochloric acid and sodium hypophosphite was 1:7.4:1.4; addition reaction time was 1.5h.

用正交试验确定了最佳工艺条件：从反应开始到加次亚磷酸钠的间隔时间0.5h；n：n：n=1 ： 7.4 ： 1.4；加成反应时间1.5h。

An oxygen-bubble and white-light speckle velocimetry method is presented.Instead ofpulsed laser and commonly used particle,a sheet like-bubble mass generated from anade wire byeletrolysing water is used as particle tracer,a white light flash set controlled by digital time delaycircuit is used as double pulsed light source,and 2-D velocity distribution in a sectional planewithin flow field can be obtained without using light sheet technique.

提出了一种氧气泡粒子白光散斑测速技术，与以往散斑测速方法不同的是，采用电解水时电解阳极丝上产生的氧气泡做为流场示踪粒子，用两个闪光时间间隔由数字延时电路控制的普通闪光灯做为散斑底片拍摄时的双脉冲光源，并且勿需片光技术，即可获得流场内部一个截面上的二维速度分布。
