By determing the photosynthetic production rates in the 46 hybrids and 21 parental inbred lines, the results show that the dominancy of average photosynthetic production rate in F1 is 16.4 %; when the parent of high photosynthetic production rate is used as female parent, the dominancy of the photosynthetic production rate in F1 is over its parent by 8.8 %, otherwise, used as male parent, by 0.9%.

通过对46个杂种及21亲本自交系光合生产率的测定结果表明：F_1平均光合生产率优势为16.4%。用高光合生产率亲本作母本时，F_1光合生产率优势超亲8.8%，反交F_1光合生产率优势超亲0.9%；母本光合生产率遗传力，大于父本光合生产率遗传力11倍。低光合生产率亲本的光合生产率遗传力大于高光合生产率亲本光合生产率的遗传力1.6倍。

The higher percentage of cross-fertilized kernel specifically expressed pattern was observed in highly heterotic hybrid, after comparison of gene differential expression between cross-fertilized and self-fertilized kernels during the early development of seed in wheat and maize, respectively. This indicated that there may be have common molecular mechanism for heterosis in different crops.

本文对玉米和小麦在种子发育前期杂交和自交间基因差异表达进行了比较，发现杂交特异表达类型与杂种优势均存在一定的正向关系，说明不同作物杂种优势形成在分子水平上具有共同点，即相同表达模式的基因或基因群在不同作物杂种优势形成中发挥一致的作用。

The diversity index and evenness index of tree species in medium-aged stands averaged 1.79 and 0.53. The dominant family for the forest was Fagaceae in terms of importance value, and the dominant tree species were Castanopsis eyrei, C. sclerophlla, Lithocarpus harlandii, and Cyclobalanopsis glauca.

肖坑亚热带常绿阔叶林的树种多样性较低，中龄林林分平均多样性指数和均匀度指数分别为1.79和0.53；依据优势度划分，该地区常绿阔叶林的优势科为壳斗科，优势种为甜槠、苦槠、青冈和东南石栎。

The paper selects Qinghai City to analyze its investment environment for both active and passive investment in a combination of environmental assessment studies and optimizes the investment environment countermeasures, in addition to use the SOWT analysis for the conduct of evaluation studies on western mining investment environment.

选取青海省矿业进行案例分析，运用SOWT分析法对其矿业投资环境进行评价研究，针对其存在的问题，提出优化投资环境的对策，促使其矿产资源优势转化为市场优势和经济优势。

The paper selects Qinghai City to analyze its investment environment for both active and passive investment in a combination of environmental assessment studies and optimizes the investment environment countermeasures, in addition to use the SOWT analysis for the conduct of evaluation studies on western mining investment environment. The aim is to take the advantage of mineral resources into market advantages and economic advantages.

选取青海省矿业进行案例分析，运用SOWT分析法对其矿业投资环境进行评价研究，针对其存在的问题，提出优化投资环境的对策，促使其矿产资源优势转化为市场优势和经济优势。

Stuber et al.(1992) considered the overdominance is the major genetic basis of heterosis in maize; Xiao et al.(1995) suggested the dominance is the major molecular mechanism of heterosis in rice. Subsequently, Yu et al.(1997) and Hua et al.(2003) demonstrated the epistasis made the siginificant contribution to heterosis in rice.

Stuber等认为，超显性是玉米杂种优势形成的主要原因；Xiao等(1995)认为显性作用是水稻杂种优势形成的遗传基础，Yu等(1997)和Hua等(2003)认为上位性在杂种优势形成过程中起重要作用。

The results showed:① The new gemplasms had high nutritive value and taste quality and were similar as the protogene type in each biochemical constitution.② The heterotic rates were negative orientation on the most of quality character,but it was evidently different from the growth vigour character.③ The external...

研究结果表明，（1）甜玉米新种质各种生化成分与原始基因型接近，营养价值高，食味品质好；（2）甜玉米品质性状优势率以负优势为主，明显不同于生长势性状的优势率；（3）普甜、甜脆、超甜玉米籽粒外观性状和糖分含量均受其各自的一对隐性基因控制

3Through analysis of the calculate results and actual fact of Shaanxi province, we can still attain below information: The latest rank of index of new economy in China shows: Shaanxi is the eighth, but the GDP per person is NO.29, so the technology and resource advantages of Shaanxi are far to convert to economic advantage, Finally, how to make the technology of the Shaanxi converting to realistic productivity farthest, and make the technology advantage converting to economic advantage, and make the big province of technology becoming a powerfully economic province which is worthy of the name, the dissertation suggests grasping a few aspects as follows: Set up the idea of exploitation new technology, establish the motive mechanism of technology innovation, establish the mechanism of guarantee the budget of scientific research, establish the mechanism of guarantee scientific personnel, construct the fair competition market environment, allotment technology resources openly in the most possible, make the resources to be allotted and used with high-efficiency, at the same time, relying on the resources advantage of Shaanxi, proceed the technique reform and technique penetration, so as to creates the higher benefit.

最后，就如何使陕西的科技优势最大限度地转化为现实生产力，使科技优势转化为经济优势，使科技大省成为名副其实的经济强省，笔者建议从以下几个方面抓起：树立新的科技开发观念、建立科技创新的动力机制、建立科研经费保障机制、建立科研人员保障机制、营造公平竞争的市场环境，科技资源分配尽可能地公开，使资源得到较高效率的配置和使用，同时，依托陕西的优势资源，进行技术改造和科技渗透，以创造出更高的效益。本研究具有以下创新点：一是使用先进的研究方法，把计算机计算和新的数学方法相结合，使计算简单化、准确化；二是使用了先进的研究思路，把陕西省和其他地区置于同一系统内，使用同一的数据处理方法和统计口径，使计算结果更科学、更符合实际，且具有可比性。
