Mass Collaboration in Earthquake Risk Management

The mechanism of mass collaboration in risk management was studied during the Sichuan earthquake under a Web-based “PeopleFinder” project, where information is contributed and shared among mass contributors. The case study is provided by a great earthquake that happened in Wenchuan County, Sichuan Province, of southwestern China at 2:28 p.m. on May 12, 2008. We witnessed and experienced the rescue and relief efforts for the great earthquake. In this article, two fundamental frameworks are developed to study the mechanism of mass collaboration. Mass collaboration is proven to be effective in a big public crisis such as the Sichuan earthquake.     

On the classification of Calligonum juochiangense and C. pumilum (Polygonaceae)

After observing specimens of Calligonum pumilum Losinsk. and C. juochiangense Y. X. Liou in both the field and in herbarium collections, it was found that the morphological characters of these two species are quite different, especially with respect of the twisted direction of fruit ribs, number of bristle rows along each rib, rigidity and degree of interweaving of bristles, as well as their geographic distribution. Therefore, it is concluded that C. pumilum and C. juochiangense should be accepted as two independent species.     

感染环形泰勒焦虫(Theileria annulata)的牛外周血白细胞的形态观察

用光镜及扫描电镜观察了体外高代培养的含牛焦虫颗粒的牛外周血白细胞的形态及在细胞周期中细胞表面的特征性变化。这种经多年传代的含虫的牛外周血白细胞恢复了分裂和繁殖的能力,目前已成为较稳定的细胞系。细胞表面具多种伪足突起,如叶状、丝状及绒毛状。细胞周期中备期细胞表面的主要特征是:S期:细胞平扁,边缘具薄的时状伪足及丝状伪足;G_2期:细胞中部隆起,表面具少量绒毛状伪足;G_1期:绒毛状结构少或无,而出现丝状及小的叶状伪足,细胞仍保持球形;M期:细胞球形,表面密被以绒毛。作者根据扫描电镜的观察认为光镜下所观察的两类细胞,实际上是反映了一种细胞处于不同发育阶段时的特征。     

A review of the distribution of all species of deer (Tragulidae, Moschidae and Cervidae) in China

Twenty-one species of deer occur in China: one species of Tragulidae, three species of Moschidae and 17 species of Cervidae. The foundation of this review is the research conducted in the early 1940s by Allen, combined with the research and investigation by the authors and other Chinese specialists since that time. This paper focuses on the tentative distribution of these species of deer for future research efforts.     

康定虫草主要寄主斜脉蝠蛾的研究

冬虫夏草是一味名贵的中药材.四川康定虫草的主要寄主斜脉蝠蛾翅面色斑多变异,可区分成“黑白斑”和“黄毛斑”两大色斑型.经交配试验和成虫形态特征(触角、口器、翅脉、前足、雌雄外生殖器和鳞片的超微结构等)的观察,证明为同一种,经鉴定是斜脉蝠蛾(Hepialus oblifurcus Chu et Wang)^**.     

黄海车牛山岛白腰雨燕的繁殖习性及种群动态

本文为作者于1980—1981年对黄海车牛山岛白腰雨燕Apuspacificus pacificus (Latham)的初步研究。内容包括对繁殖习性的观察;对繁殖周期、卵孵化率、雏鸟成活串以及出生率等的统计。并对海岛生态环境下白腰雨燕种群数量的变动及其影响因素,作初步探讨。     

蛙卵黄粒晶形区向非晶区过渡的电镜观察及伪彩色图象处理

用水溶性氨基树脂作为电镜标本包埋介质包埋早期卵裂时的黑龙江林蛙卵;用透射电镜观察了卵黄粒晶形体向非晶区转变的过程;一部分电镜照片用伪彩色图象处理技术转换成彩色照片以提高其清晰度。晶形体向非晶结构转化主要有两种形式:1.沿晶形体表面成排地脱落晶分子并在晶形体表面形成台阶样结构;2.晶分子参差不齐地成群脱离晶形体并在晶形区与非晶区之间形成一个似晶非晶的过渡区。脱离晶形体后的晶分子参加到非晶区,使深色亚区扩大并在其中酝酿成“微滴”样结构。若干“微滴”汇合并转变成微泡。伪彩色图象处理能较清楚地显示出卵脂蛋白半分子(一个亚单位)独立脱离晶形体的现象。讨论了引起晶分子脱离晶形体的可能??原因。     

脐鳞属地衣一个新种(英文)

本文描述了脐鳞属地衣一个新种:褐脐鳞。这个新种类似红脐鳞,但地衣体上表面为灰褐色并且不合松萝酸。本种与泡状脐鳞的区别是不含富马原岛衣酸及地理分布的差异。
