动补情态否定构式与“不”字否定构式的比较分析  [PDF]
段业辉,刘树晟,张怡春
- , 2013,
Abstract: 动补情态否定构式“V不C”表示“不可能”,“不”字否定构式“不VC”表示“能而不做”。二者的成因都是概念整合,但类型不同。前者是由具有因果相关性的两个事件前后相接“截搭”而成,后者是由表示“未然”否定的“不X”和表示“致使”义的“VC”构式“糅合”而成。情态否定构式具有致事的施动性和言者的预期性的语义特点,“不”字否定构式具有致事对变化的意志性和致事对变化的可控性的语义特点。
The modal negative construction means “being impossible” while the“bu”-style negative construction “being possible but unwilling to do”. These two constructions, though both motivated by conceptual blending, are different in how they are blended into being: the former is a haplology of two adjoining events; but the later is the blending of buX construction(indicating unaccomplished negative)and VC construction(bearing a causative meaning). The modal negative construction means causative action and speaker’s expectation. The“bu”-style negative construction expresses the causer’s will upon change as well as his control over change
重组式股权分置改革对价不课税  [PDF]
王骏
财会月刊 , 2009,
Abstract: 近期,各地税务机关纷纷转发了《国家税务总局关于股权分置改革中上市公司取得资产及债务豁免对价收入征免所得税问题的批复》(国税函[2009]375号)。该批复称,根据《财政部国家税务总局关于企业所得税若干优惠政策的通知》(财税[2008]1号)的规定,《财政部国家税务总局关于股权分置试点改革有关税收政策问题的通知》(财税[2005]103号)的有关规定,自2008年1月1日起继续执行到股权分置试点改革结束。股权分置改革中,上市公司因股权分置改革而接受的非流通股股东作为对价注入资产和被非流通股股东豁免债务,上市公司应增加注册资本或资本公积,不征收企业所得税。  国税函[2009]375号文件的最大受益者就是一系列进行重组式股权分置改革的上市公司,而来自广东的上市公司ST博信是这个文件出台背后的“始作俑者”。ST博信正是因国税函[2009]375号文件的姗姗来迟而彻底越过了股权分置改革的税收门槛。

Abstract: The subject of the study was investigation of influence of substituent type on the properties of starch derivates in diluted solutions. Three samples were prepared: two anionic (carboxymethyl starch, CMS) and one cationic starch (KS). Starch derivates were synthesized in two steps. The first step was preparation of alkali starch by the addition of sodium-hydroxide to the starch dispersed in ethanol or water. In the second step, the required amount of sodium monocloracetate or 3-chloro-2-hydroxypropyl-threemethylamonium chloride was added to the obtained alkali starch in order to prepare CMS or KS, respectively. The degree of substitution of carboxymethyl starch was determined by back titration method, and the degree of substitution of cationic starch was determined by potentiometric titration. The degrees of substitution of prepared samples were: 0.50 (assigned as CMS-0.50) and 0.70 (assigned as CMS-0.70) for carboxymethyl starch and 0.30 (assigned as KS-0.30) for cationic starch. The properties of starch derivatives in dilute solutions were investigated by the methods of static and dynamic light scattering. Aqueous solutions of sodium chloride of different concentrations were used as solvent. The values of the mass average molar mass, MW, radius of gyration, Rg, and second virial coefficient, A2, were determined for all samples together with hydrodynamic radius, Rh. Molar masses of the samples were: 5.06×106, 15.4×106 and 19.2×106 g/mol for CMS-0.50, CMS-0.70 and KS-0.30, respectively. The samples, CMS-0.70 and KS-0.30 had similar molar mass and hydrodynamic radius, but radius of gyration of KS-0.30 was smaller then radius of gyration of CMS-0.70 at all sodium chloride concentrations. Consequently, ρ value for KS-0.30 was smaller then for CMS-0.70, as a result of more compact architecture of KS-0.30 then of CMS-0.70. Kratky graph confirmed this result. For all samples, radius of gyration and hydrodynamic radius decreased with increasing of sodium chloride concentration, but decrease of the radius was greater for CMS-0.50 then for other two samples due to its significantly lower molar mass. On the other hand, change of both radius of gyration and hydrodynamic radius of CMS-0.70 and of KS-0.30 with increasing sodium chloride concentration were similar. It can be concluded that the decrease of both Rg and Rh with increasing sodium chloride concentration in water depends far more on molar mass than on degree of substitution.
中高盐度NaCl―H2O包裹体的密度式和等容式及其应用  [PDF]
地质论评 , 2001,
Abstract: 由于现有的盐水溶液热力学状态方程比较复杂,对于盐水包裹体使用很不方便.笔者在已推导的低盐水包裹体热力学公式基础上,根据实验数值,采用数学拟合法,得到中高盐度(≥23.3%)NaCl-H2O溶液包裹体较精确的流体密度计算式:ρ(g/cm3)=A+B?th+C?th2(A=A0+A1?w+A2?w2;B=B0+B1?w+B2?w2:C=C0+C1?w+C2?w2)和包裹体等容式:p(×105Pa)=a+b?t+c?t2.当测定出包裹体的均一温度(th,℃)和含盐度(w,%),代入密度式即可计算包裹体的流体密度.再找出此密度、盐度的等容式中参数(a、b、c),将这一等容式和其他公式联立,可求得包裹体的形成温度和压力.本文还列举了利用密度式和等容式计算的3个实例.

Abstract: 不结球白菜〔Brassicacampestrisssp.chinensis(L)Makino〕在南方夏季常受高温伤害,以致影响其周年均衡供应。因此,深入研究不结球白菜的抗热机理,对于指导选育抗热品种具有重要的理论价值和实际意义。但有关高温对细胞膜透性、抗坏血酸含量、MDA和过氧化物酶活性方面的研究较少。
