In accordance with increasing concentrations of Ca~(2+), Ca~(2+)-ATPase and H~+-ATPase activity in plasma membrane and tonoplast of cucumber root were increased significantly at first, then decreased slightly later; H~+-ATPase activity in plasma membrane and tonoplast of cucumber leaf was changed unremarkably; Ca~(2+)-ATPase activity in plasma membrane and tonoplast of cucumber leaf was increased significantly at first, then decreased slightly later.

低温下，随Ca~(2+)浓度的升高根中质膜和液泡膜Ca~(2+)-ATP酶和H~+-ATP酶活性及叶片中质膜和液泡膜Ca~(2+)-ATP酶活性先升高后下降，叶片中质膜和液泡膜H~+-ATP酶活性无显著变化，说明适当增加营养液中Ca~(2+)浓度后，可提高ATP酶的活性减轻低温伤害。

Thereafter B-A1 paste-layer diffusion technology and close-tube Ga-diffusion technology had been developed, while the former can lead to relatively large the base-region deviation and abruptly varied region in Si, which caused severe decentralization of current amplification parameter β, bad thermal stability and high tr; the latter needed the relatively difficult pack technique, with poor repeatability , high rejection ratio, and poor diffusion quality and production efficiency.

此工艺发明以来，克服了上述两者的弊端，杂质浓度和结深能准确控制而又能任意调整，可进行低、高浓度阶段性掺杂，得到元素Ga在Si中的理想分布，而且表面浓度均匀一致、重复性好、合格率和优品率高，改善和提高了器件的综合性能。
