A comparative analysis is given of the data on measuring the deformation of bilayer lipid membranes (BLM) by the optical (reflexometry) and capacity methods with regard to both the electrostatic forces compressing the bilayer and the changes in bilayer tension. The essential difficulties in interpreting (in terms of elastic modulus) the data on electrostriction changes in BLM integral capacity are shown. Based on the optical data it is shown that most "soft" BLM formed from lipid solution in short-chain (below n-decane) alkanes have a cross-section elasticity modulus E no less than 10(-7) Pa even at zero frequency. The elasticity modulus in the membrane plane upon isotropic tension (E) is about two times as much as E. At a voltage jump, the time of establishing a new value of the contact angle theta between the volumic phase (torus) and the bilayer and, respectively, of a new value of bilayer tension does not exceed 0.25 ms.
对通过光学（反射测量法）和电容法测量双层脂质膜（BLM）变形的数据进行了比较分析，涉及压缩双层的静电力和双层张力的变化。展示了在解释（根据弹性模量）BLM积分电容中电致伸缩变化数据时存在的主要困难。基于光学数据表明，即使在零频率下，由短链（低于正癸烷）烷烃中的脂质溶液形成的大多数“软”BLM的横截面弹性模量E不少于10^(-7) Pa。在各向同性张力下膜平面内的弹性模量（E）约为E的两倍。在电压跳跃时，体积相（圆环）与双层之间建立新的接触角θ值以及双层张力新值的时间不超过0.25毫秒。
