The results showed that the use of ultrasond increased the content of active ingredient in the sorbents, improved the pore structure, and thinned the particles.

研究结果表明，超声浸渍促进活性成分的负载，丰富脱硫剂的孔隙结构，并具有细化和均化颗粒的效果。

The RTS profile generally will result in brighter and shinier joints and fewer problems concerning solderability, since the solder paste reflowed in a RTS profile will still contain its flux vehicle throughout the entirety of the preheat stage.

在 RTS 曲线中，锡膏中的助焊剂媒介在整个预热过程中的存在，会促进焊料的润湿，因此 RTS 曲线可以用难以焊接的合金和元件上。

DCMU clearly prevents the stimulating effect of light,but sodium benzoate,a free radical scarvenger,has no effect.

光明显抑制乙烯形成，敌草隆对光促进乙烯形成有明显抑制效应，而自由基清除剂苯甲酸钠作用不明显。

Results showed that low contents of Cd has promotion effect on Oryza Sativa, but high contents of Cd has not obvious restrain on it. The total trend of distribution of Cd in Oryza Sativa is root＞stem＞shell＞rice. The relation between Cd contents in rice and total Cd in soil as well as availability Cd in soil has been investigated. The result showed that both the total Cd and the availability Cd had notably correlation with content of Cd to rice, and the critical point were CaCl2-Cd=0.71mg/kg, DTPA-Cd=1.34 mg/kg, EDTA-Cd=0.76 mg/kg, NH4OAc-Cd=0.77 mg/kg.

研究表明：低浓度的镉对水稻生长稍有促进作用，高浓度的镉对其生长并没有明显的抑制作用；镉在水稻植株中总的分布趋势为根＞茎＞稻壳＞糙米；用4种有效态提取剂（0.1 mol/L CaCl2、DTPA、0.05 mol/L EDTA和1 mol/L NH4OAc）浸提出的有效态镉的含量和土壤中镉总量与水稻糙米中镉含量均达到显著相关水平，并确定了它们的临界值分别为CaCl2-Cd=0.71 mg/kg， DTPA-Cd=1.34 mg/kg， EDTA-Cd=0.76 mg/kg， NH4OAc-Cd=0.77 mg/kg。

Shows that FB can promote bamboo root to develop obviously, restrain rice growth and improve the rate of alive tissue cultured aloe seedling.

进行混合菌剂生长效应测定，表明FB能显著促进富贵竹生根，抑制水稻生长；提高芦荟组培苗成活率。
