The main content is concerned with the following aspects:(1) It discusses the electric-optical effect in the theory about the interaction of γ-rays and materials, Compton effect and electron pair effect and the functional relationship between the three basic effects and γ-rays energy and atomic number, thus laying the foundation of dual energy γ-rays transmission method.

主要内容有如下几个方面：(1)讨论了γ射线与物质相互作用理论中的光电效应、康普顿效应和电子对效应，以及这三个基本效应与γ射线能量和物质的原子序数之间的函数关系等问题。由此构成了双能γ射线透射法的基础。

The wood structures of Lauraceae were characterized by most diffuse porous; most pores solitary, less multiple and cluster pores; simple and scalariform perforation with few bars; most solitary pore; alternate intervessel pitting; most of rays multiseriate, less uniseriate; all of rays heterogeneous, mostly heterogeneous Ⅲ and Ⅱ type rays; most of axial parenchyma paratracheal type, less banded or marginal type; oil cell and mucilage cell in axial parenchyma cell or ray cell; mostly fiber tracheid and libriform fiber, less septate fiber.

结果表明：除檫木外，其它木材的管孔分布均为散孔材，具较高的单孔率；导管分子穿孔板兼有单穿孔和梯状穿孔2种或者仅具有单穿孔；导管间纹孔式为互列；导管－射线间纹孔式类型丰富，主要为刻痕状和大圆状。木射线有单列和多列射线2种类型，单列射线稀少、短，多列射线数量多；射线组织主要为异形Ⅲ和异形Ⅱ；轴向薄壁组织以傍管状为主，少数有带状或轮界状。油细胞和粘液细胞普遍存在于射线薄壁细胞或轴向薄壁细胞中。木纤维由韧性纤维和纤维管胞组成，部分树种具分隔纤维。

The CCTV and local meteorological observatory broadcasts the intensity of ultrsviolet rays every day, obviously harmful ultrsviolet rays harmful to human body, and people gradually paid much attention to ultrsviolet rays, clinical proof: The eye frequently receives the ultraviolet radiation, it can cause electrophoto ophthalmia.

中央电视台和地方气象台现在每天播报紫外线的强度，可见有害紫外线对人体的伤害已逐步被人们重视，临床证明：眼睛经常受紫外线照射，就会导致电光性眼炎，日光性眼炎或雪盲。

But the sun's rays then reach us despite having passed, first, through an enormous thickness of the higIT strata of the air, the minute dust of which reflects maximum of the higIT strata of the air, the minute dust of which reflects maximum of the blue rays away from us, leaving the complementary yellow light to pass on, Then, the somewhat coarser dust reflects the green rays, leaving a abundance orange-coloured light to pass on; and finally some of the yellow is reflected, leaving almaximum pure red.

这就充分呈现了低空尘埃的数量之大。但是太阳的光线终于到达了地面。它们先是穿过厚度极大的高空大气层，其中的细微尘埃把大部份蓝色的光反射掉了，让补色的黄光继续通行。然后，粗粒尘埃又反射掉绿色的光，让偏橙色的光继续通行。最后，部份黄色的光也反射掉，剩下几乎是纯红色的了。
