Both national and local governments have been paying great attention to the work of industrial standardization with the enormous increase in international trade after China joined WTO. According to the standards revising plan of Standardization Administration Committee of China (SAC),TC54 has already revised a series of national standards and industrial standards for foundry operations,and proposed some new ones. As a result,some old fashioned standards containing low-level techniques have been gradually discontinued or replaced with new versions.……展开更多

This initiative will tremendously subvert the traditional language learning and testing mechanism, bring phenomenal transformations and innovations to the future language learning and teaching approaches and methodologies, and meanwhile impose great influence on the language concerning administration and profession.展开更多

Monoecious fig species and their pollinating wasps are in conflict over the use of fig ovaries which can either produce one seed or one wasp. From observation on Ficus virens Ait., we showed that female flowers with outer layer of ovaries (near to the wall of syconium) had no significant difference from that with inner and interval layer of ovaries (near to the syconium cavity), in which most seeds and wasps were produced. This meant that fig tree provided the same potential resource for seed and wasps production. Observation indicated that there was usually only one foundress in syconium at female flower phase and no com- petition pollinators. Measurement of the style length of female flowers and the ovipositor of pollinators indicated that most ovaries could be reached by pollinator’s ovipositor. However, at the male flower phase, production of seeds was significantly more than that of wasps including non-pollinating wasps but there was no significant difference between seed and pollinating wasp production when without non-pollinating wasps produced. This result indicated that non-pollinating wasps competed ovaries not with seeds but with pollinating wasps for ovipositing. Bagged experiment showed that the sampling fig species was not self-sterile which was important for figs and wasps to survive bad season. Seed production in self-pollinated figs was not significantly different from total wasps in- cluding non-pollinating ones. This might be related with the weaker competition among wasps since bagged figs were not easy to reach by wasps from outside.展开更多

Planning ahead, from the perspective of sustainable economic development, China badly needs to transform from factor-driven growth to efficiency-driven and innovation-driven growth, the key to which is to further encourage the liberalization of thought, promote reform and opening-up, unswervingly follow the path of economic liberalization, marketization and privatization, to establish an inclusive modern market system, to allow the market to play a decisive role in resource allocation and the private economy to play a dominant role in the national economy. The market-oriented reform is a complicated project and China is faced with at least three different aspects of reform in some key areas--the main body of private economy, the liberalization of financial market and the marketization of land. Meanwhile, China needs to efficiently balance three elements of good governance, that is, the rule of law, execution and democratic supervision, so as to facilitate the modernization of state governance system and governance capability.展开更多
