Since phosphamidases are more abundant in neoplastic tissue than normal tissue, twenty-three N-phosphorylated nitrogen mustards and ethylenephosphoramides were prepared in order to find anticancer agents with more selectivity against the malignant tumours. The compounds synthesized were listed in the Chinese text in Table 1. Preliminary pharmacological tests have revealed that the compounds (II, III, VII, VIII, and XXII) have remarkable inhibitory action against Sarcoma 180 in mice, and compound (I) possesses...

Since phosphamidases are more abundant in neoplastic tissue than normal tissue, twenty-three N-phosphorylated nitrogen mustards and ethylenephosphoramides were prepared in order to find anticancer agents with more selectivity against the malignant tumours. The compounds synthesized were listed in the Chinese text in Table 1. Preliminary pharmacological tests have revealed that the compounds (II, III, VII, VIII, and XXII) have remarkable inhibitory action against Sarcoma 180 in mice, and compound (I) possesses pronounced inhibitory activity against Yoshida Ascites sarcoma and several other animal tumours. The last one is now under clinical trials.

本文叙述了二十三个磷酰胺和磷酰胺酯化合物的合成,以研究其抗肿瘤活性。合成的化合物部分经过了动物筛选。化合物II、III、VII、VIII和XXII对小鼠肉瘤180有明显抑制作用。化合物1对多种动物肿瘤具有显著活性,并已推荐临床试用。

In this paper, formulas of the potential of deformation force and its components in three (N-S, B-W, and vertical) directions have been deduced, they principally include coordinate of instantaneous pole of earth rotation and geographic longitudes and latitudes. The characteristics of change in time and space of the potential of this force and its components have been discussed. While different in way of deduction and longitudinal directions from the same formulas abroad, these formulas are convenient for processing...

In this paper, formulas of the potential of deformation force and its components in three (N-S, B-W, and vertical) directions have been deduced, they principally include coordinate of instantaneous pole of earth rotation and geographic longitudes and latitudes. The characteristics of change in time and space of the potential of this force and its components have been discussed. While different in way of deduction and longitudinal directions from the same formulas abroad, these formulas are convenient for processing of the astronomic data in our country.The authors have revealed the regular connection between some features of climatic change in our country, the indices of the general circulation in the Northen Hemisphere and the shifts of the earth poles. The cause of possible influence of earth pole shift on climate was explained and the time scale and space change of the influence were discussed also.

本文推导了包含地球转动瞬时极坐标和地理经纬度的极移变形力位势和该力在东西、南北、垂直三个方向上的分量的表达式,它与国外同类工作的推导途径不同,经度取向不同,便于利用我国天文资料进行计算。文中讨论了极移变形力位势和该力三个分量的时空变化规律及其量级估计。 作者揭示了我国气候某些演变特点、北半球若干大气环流指标与地极移动之间的规律性联系。 并对地极移动可能影响气候的原因提出了看法,讨论了前者可能影响后者的时间尺度和空间效应问题。

Photoelectrochemical measurements are reported on three n-type compounds semicon-ductors.The method basically consists of the measurement of the photo-current ofSC/EL Schottky berrier as the function of applied reverse bias. Weakly absorbed lightis used,so that the light penetration depth is much larger than the Schottky barrierwidth.The minority carrier diffusion length L_p has been obtained by means of an ex-trapolation method and a fitting method.Results obtained are L_p=0.036μm for GaP(N_D=3.9×10~(19)cm~(-3)....

Photoelectrochemical measurements are reported on three n-type compounds semicon-ductors.The method basically consists of the measurement of the photo-current ofSC/EL Schottky berrier as the function of applied reverse bias. Weakly absorbed lightis used,so that the light penetration depth is much larger than the Schottky barrierwidth.The minority carrier diffusion length L_p has been obtained by means of an ex-trapolation method and a fitting method.Results obtained are L_p=0.036μm for GaP(N_D=3.9×10~(19)cm~(-3). L_p=0.8μm for GaAs (N_D=7×10~(17)cm-(3)), L_p=0.1μm for GaAlAs.(N_D=8×10~(16)cm~(-3)) respectively.

本文提出的拟合法是以光响应作为αW和αL_p的函数,在知道α的情况下,拟合曲线求得L_p值.结合外推法,反过来校正α值,似可以补充外推法的不足和得出较正确的L_p值.我们分别采用拟合和外推两种方法测定扩散长度L_p,已测得的各种半导体材料扩散长度分别为GaP(N_D=3.9 × 10~(19)cm~(-3))L_p= 0.036μm,GaAs(N_D=7 ×10~(17)cm~(-3))L_p=0.8μm,GaAlA_s(N_D=8 ×10~(16)cm~(-3))L_p=0.1μm.
