從外延層載流子壽命與晶體管放大倍數，表面復合率與漏電流，以及外延層載流子壽命與晶體管開關速度等方面對于輸出級縱向pnp管進行了較為詳細的設計與分析，達到了電路中對輸出級縱向pnp管主要參數指標的要求。 -
Measurement of mine surface air leakage rate with equivalent method
等值法測定礦井外部漏風率 -
Two typical examples analyses are conducted for the average conditions both of winter and summer climates under vapor diffusion and air leakage. a further discussion is set forth to determine the main factors that the moisture accumulation in wall is affected. it is found that the factors are the relative humidity at the wall surface, indoor temperature, permeability, air pressure difference and rate of the infiltrative or exfiltrative airflow
本文首先研究了墻體內的濕氣遷移過程，詳細分析了濕積累現象形成的原因，通過對夏、冬兩季平均氣候下墻內溫度、水蒸氣壓力、相對濕度及濕積累在僅有擴散、擴散與空氣滲透同時存在等情況所作的具體計算，發現墻內、外表面的相對濕度、室內溫度、滲透率、空氣壓差以及空氣的滲流速度是影響墻內濕積累的主要因素。 -
This article describes the main forms of water leakage through exterior walls and on the basis of hydromechanics and surface physicochemistry deduces theoretical formulas for the computation of the depth of infiltration of water through walls, its infiltration rate and infiltration duration and thus makes quantitative evaluation of the main influential factors and their influential degree for the water leakage through exterior wall
介紹了建築外墻滲漏的主要形式，並根據流體力學及表面物理化學理論，推導出水在墻體中滲透深度、滲透量及滲透時間的理論計算公式，從而對外墻滲漏的主要影響因素及其影響程度進行定量的評估。
