Both CaCN2 and urea inhibited the chlamydospore germination, mycelial growth and sporulation of the pathogen, but CaCN2 by using at the rates of 0.5 and 1.0%, had two inhibition zones for chlamydospore germination with time while urea had only one. Calcium cyanamide was also more effective on reducing mycelial growth and sporulation of the pathogen than urea did. Therefore, the suppression of pea wilt might be due to fungicidal effect of the intermediate products including hydrogen cyanamide and urea from calcium cyanamide.

由氰氮化钙（0.5及1.0%处理者）之抑制曲线在不同的时间出现两个抑制区，而尿素则仅有一个，及氰氮化钙对萎凋病菌菌丝生长及产胞的影响远较尿素为甚，显示氰氮化钙之所以能有效抑制萎凋病的主要因子，或许是来自其中间产物，包括尿素及氟酸的杀菌作用。

On the basis of MEBT, a new technique hypothesis of injecting MEBO under the eschar was proposed to have 6 biochemical reactions available, such as hydrolysis, enzymolysis, saponification, rancidify, lipofication, esterification of MEBO with necrotic tissue of the eschar, then to realize liquefaction and quick defluxion of necrotic tissues, This finally to play a role of regenerative action of MEBO in situ to turn potential regenerative cells into skin stem cells that would further proliferate and differentiate to form skin tissues, reaching the goal of physiologically repairing wounds.

最后提出了在烧伤湿性医疗技术正规治疗的基础上，同时进行痂下注射MEBO的新技术设想，其目的是使痂下组织尽早接受MEBO的治疗，痂下发挥MEBO的水解、酶解、皂化、酸败、脂化、酯化六大生物化学反应，促使坏死组织痂下痂外一起液化，尽快脱落；而且在痂下发挥MEBO原位再生作用，使潜能细胞转变成皮肤干细胞，干细胞进一步增殖分化形成皮肤组织，达到创面生理性修复之目的。

The results show: in a specific concentration range, the solubility in neutral solution of SOL, as well as the surfactivity, the ability to reduce ITF and the wettability on the condition of non- alkali are better than the lignosulfonate in market.While using as sacrifice agent, the modified lignosulfonate can reduce 60% of the mahogany sulfonate and 50% of the α-alkene sulphonate which both are adsorbed on the oil sand surface.
