A preliminary inquiry about the problem of second births outside the plan]

In 1981, the population growth in China was revived and showed a new trend towards a rapid increase. In general, the rate of numerous births in one household was down, the rate for a second birth outside the plan was up sharply, and the number for a second birth outside the plan exceeded the number for multiple births in average families. As a result, how to control the second birth outside the plan has become a crucial problem for population control. Under present conditions, numerous births in each household are normally related to the financial situation of each household, the sex of earlier births, and the educationa background of the parents. The current increase in second births is not caused by financial reasons. Instead, it is caused by social and psychological reasons. The traditional belief in favor of having more male children for security in one's old age and for continuation of one's family line is still deeply rooted in the people's minds. In order to eliminate such tradtional influence, more work in ideological education is needed so that the common people may understand the need for birth control and change their traditional view on population. With the establishment of a responsible production system in the rural areas, measures for economic restriction and reward should be taken. In addition, late marriages should be enouraged, and a new tax system based upon population count in each household should be adopted so that additional revenues may be collect for educational and other expenses, and social insurance for old people should be expanded. If all these measures are taken successfully, the problem of second births outside the plan can be solved.     

抗生素放线菌种低温保存的研究

本文研究了产生抗生素的两种放线菌种(链霉菌和庆大霉素产生菌)低温(-196℃)保存的方法,讨论了在保存过程中的降温速率、复温速率以及抗冻剂等对保存效果的影响。经低温保存后的菌种,其菌落形态、孢子结构均无明显可见的变化,存活率达90%以上,生产水平优于砂土保存方法。

高纯度Cr26Mo钢焊缝的力学和耐碱蚀性能

本文用钨极氩弧焊附加氩气延续保护的焊接方法对高纯度 Cr26Mo 钢进行可焊性研究。检验焊缝质量和力学性能,用失重法和电化学方法测试焊缝在阿蒙古天然碱苛化烧碱的高温浓碱液条件下的腐蚀行为,确定了腐蚀速度,评定了耐蚀性等级。观察焊缝金相组织,分析焊缝区碱蚀表面的腐蚀形态,判别力学性能试样的断口形貌特征和断裂类型,并鉴定了腐蚀过程中所形成的保护膜和沉淀物的形貌和晶体结构。表明该钢焊缝有较好的力学性能和耐内蒙天然碱苛化烧碱液的性能。     

盐分胁迫对中华补血草和高粱体内脯氨酸、脱落酸含量的影响

盐分胁迫条件下,中华补血草和高粱体内脱酸含量在12h内随NaCl处理浓度的增加而增高,随后则下降;脯氨酸含量则随NaCl处理浓度的增加和处理时间的延长而增加.外源脱落酸可以促进中华补血草和高粱体内脯氨酸含量的增加。     

Making globalization work for Chinese higher education by building bridges between internationalization and multiculturalism

The rapid expansion of higher education in China is bringing together two phenomena, internationalization and multiculturalism. This study explores the question of what Chinese universities are doing to bridge the gap between these two. Three types of higher education institutions attended by minority students are selected: a university under the governance of an ethnic autonomous region, located in Inner Mongolia; a university under the Central Ministry of Education in Beijing, and a university under the Ethnic Affairs Bureau, specifically designated for nationalities, in Hubei Province. A content analysis of selected relevant documents and interviews with university academic/administrative staff, Han and ethnic minority students were carried out. Chinese universities seem more than willing to internationalize for status advancement. However, multiculturalism in the sense of recognition of ethnic minority cultures, is not viewed as bringing higher status. The implications for bridging internationalization and multiculturalism are raised.
