Lychee was indiginous to South China. It has earned the reputation of "A delicious fruit designated to the Southern Soil. " But a rather complete and systematic historical monograph of its culture and utilization is still not yet found. So the present article is just a preliminary trial report with the sole purpose of reviewing some historical facts pertaining to the lychee fruit tree.The present article is based on a rather sound and broad summation of interrelated bibliographies starting with the original naming of the word lychee, then, tracingup to the varietal names , as well as the distribution of the fruit tree at home and abroad , down to the cultivation and its utilization. The contents of the present article include the different stages of historical development of the traditional techniques in lychee propagation,seedling plants ,planting , breeding and cultivation, plant protection,fruitharvesting and methods of storage. A brief account of each of the above items is made.Lastly, some sort of bird's eye view summary on each of the pertinent bibliographies of lychee topics is concisely and comprehensively made for the convenience of further research and reference for the readers on the lychee fruit.  原产中国的荔枝,向有“奇果标南土”的称誉,但关于它栽培和利用的历史,现还未发现有较系统、较全面的专著。本文企图在这方面,试抛引玉之砖,作出初步探索。 主要是广泛搜集有关的古文献为考证根据,先从荔枝的原始命名谈起,次从其品种名目、产地分布以至栽培利用(包括繁殖、育苗、种植、培育、防护、采收、贮藏、加工等传统技术)等方面的历史发展过程,分别作简括的叙述。 最后,用“提要”(解题)方式,将历代有关荔枝的专题文献,作出鸟瞰式综述,为今后进一步征文考献、综合分析的研究工作,提供一些线索和方便。  This paper gives a new method for finding out the gravitational red shift, velocity red shift and mass of an object so long as we know its observed values of red shift and deflection of the object's radio wave grazing a deflection object or some related data in gravitational lens phenomenon.

This paper gives a new method for finding out the gravitational red shift, velocity red shift and mass of an object so long as we know its observed values of red shift and deflection of the object's radio wave grazing a deflection object or some related data in gravitational lens phenomenon. Basic formulas used are as following: (Ⅰ) Relation between the bending of light rays and the frequency shift of spectral lines φ = where φ is the deflection, GM/C2Ris the dimensionless surface potential of the deflecting object, zv1 and zv2 are respectively gravitational frequency shift before and after grazing. (Ⅱ) Additive rule of gravitational red shift zv = zv1+ zv2 + zv1 ·zv2 where zv is the total gravitational red shift.(Ⅲ) Transformation of gravitational red shift zv + zλ +zv·zλ=ΔC/C where AC/0 isthe rate of change of the velocity of light. If it is known, the two forms of gravitational red shift zv and Zλ will be given interchangeably through transformation, so that formula (Ⅱ) can be transformed into zλ=Zλ1 + zλ2 + 2λ1·Zλ2 which takes the same form. Thus we can say: Additive rule of gravitational red shift must be invariantthrough the transformation. (IV) The rate of change of the velocity of light ΔC/C=in the general theory of relativity, where c0 is the velocity of light in vacuum CA, cc and UA,UC is respectively the velocity of light and dimensionless potential at points A. C in the field. (Ⅴ) Additive rule of the gravitational red shift and velocity red shift Zλ = zλ0 + Zλ + zλ0·zλ where Zλ0 is the velocity red shift, Zλ is the observed value of red shift of the object. The wave length λ and the frequency v should play an equivelent role in representing laws of nature, i.e. through the similar transformation ofred shift, this form of additive rule of red shift remain tmchanged.Example I QSO 3C279; The observed values of red shift and deflection are known to be 0.536 and 1.75 respectively, the deflecting object is sun, then we can evaluated successively zv1, zv,UA, UC and Δc/c, and at the end obtain the gravitational red shift zλ = 3.7768 and the velocity red shift zλ0 = 0.6786, the negative sign denotes that 3C279 has the violet shift and move with velocity 0.3c towards us. It is currently belived that all of QSO are recessing away from us. In fact, the phenomenon of the stronger gravitational red shift prevailing over velocity violet shift sometimes do occur, so it appears that an imaginary recession seems to take place. It is said that the linear dimension of QSO is usually several light years, or even several light months, then the mass of QSO 3C279 Ms = 1012±1M can be obtained from GMs/C2RS = 0.3935.Example ⅡThe double QSO 0957 + 561 A. B: For the double QSO We know that: n = 2, δ( = α1/α2) = 1.148, the spread angle α( = α1 + α2) = 5".7 and the observedvalue of the red shift Zλ = 1.405. Using S. Refsdal's formula we know that the order of magnitude of GM/c2r1 and GM/c2r2 are both 106. Although the path of radio wave is different for A, B, the total value of gravitational red shift should be the same, For this reason, we havez12 and GMs/C2RS = 0.38 an=21×106, so that zλ = 63 ×06 and zλ0=1.405.It confirms that the red shift 1.405 of the double QSO 0957 + 561 A..B is velocity red shift. Moreover, we obtain that the mass of 0957 + 561 A.B is Ms = 108±1M. This result seems to be small as compared with result from other methods. The reason may be the value of n used is a little too. Because n = 2 and n > 2 indicate respectively the position of the deflecting object is at the middle point from the double QSO to the Earth and more near to the double QSO than to the Earth. It might be more probable that n > 2 than n = 2. In short, the three quantities: mass M s. radius Rs and ratio n are inter related. How large are they after all? It is still a problem of significance.The above statements are all based on plane spacetime, but in the cosmological space of the larger scale we should consider the curved spacetime modification. Actually, the complicated structure and some oth  本文提供一种新方法、以求某天体的引力红移、速度红移和质量,只要事先知道它的红移观测值和偏转角观测值(指的是它的发射线掠过折射天体如太阳所弯曲的角度或者引力透镜中的有关数据)。 所要用的基本公式如下:(一)光线弯曲与光谱频移关系式式中φ为偏转角,GM/c~2R为折射天体无量纲表面引力势,z_(v1)和z_(v2)分别为射线掠过折射天体之前和之后的引力红移。(二)引力红移相加法则 z_v=z_(v1)+z_(v2)+z_(v1)·z_(v2)。式中Z_r为总的引力红移。(三)引力红移变换式△c/c=z_λ+z_v+z_λ·z_v。式中△c/c为光速变化率,只要它为已知,则引力红移的两种表示式z_λ和z_v可以相互交换得到。通过这种变换,式(二)可以变成z_λ=z_(λ1)+z_(λ2)+z_(λ1)·z_(λ2),而形式完全相同.我们叫它为引力红移相加法则是变换不变的。(四)光速变化率。它是根据广义相对论的公式c=c_0(12U)(1+2U)~(1)推得的。式中c_0为真空中光速,c_A、c_C和U_A、U_C分别为场中A、C两点的光速和无量纲引力势。(五)引力红移和速度红移相加法则。Z_λ=z_(λ0)+z... 本文提供一种新方法、以求某天体的引力红移、速度红移和质量,只要事先知道它的红移观测值和偏转角观测值(指的是它的发射线掠过折射天体如太阳所弯曲的角度或者引力透镜中的有关数据)。 所要用的基本公式如下:(一)光线弯曲与光谱频移关系式式中φ为偏转角,GM/c~2R为折射天体无量纲表面引力势,z_(v1)和z_(v2)分别为射线掠过折射天体之前和之后的引力红移。(二)引力红移相加法则 z_v=z_(v1)+z_(v2)+z_(v1)·z_(v2)。式中Z_r为总的引力红移。(三)引力红移变换式△c/c=z_λ+z_v+z_λ·z_v。式中△c/c为光速变化率,只要它为已知,则引力红移的两种表示式z_λ和z_v可以相互交换得到。通过这种变换,式(二)可以变成z_λ=z_(λ1)+z_(λ2)+z_(λ1)·z_(λ2),而形式完全相同.我们叫它为引力红移相加法则是变换不变的。(四)光速变化率。它是根据广义相对论的公式c=c_0(12U)(1+2U)~(1)推得的。式中c_0为真空中光速,c_A、c_C和U_A、U_C分别为场中A、C两点的光速和无量纲引力势。(五)引力红移和速度红移相加法则。Z_λ=z_(λ0)+z_λ+z_(λ0)·z_λ 式中z_(λ0)为速度红移,Z_λ为红移观测值。我认为波λ和频率v在描述自然规律方面应有同等作用,即通过类似的红移变换,此红移相加法则的形式仍然不变。  Measurement is made by flameless graphite stove method using atomic absorbing spectrometer of cadmium content in the hearts, livers, lungs and kidneys of 7 cases dead bodies which had no history of professional exposure to cadmiumor living in cadmium polluted areas.
