浅谈人造薄木生产中单板的漂白

详细阐述了木材颜色的成因及漂白机理，重点介绍了人造薄木生产过程中单板漂白工艺。研究表明，经漂白处理的单板，颜色明显变浅，色调也比较均匀，而且还消除了板面污染，对单板的染色十分有利。     

Hyperadrenocorticism associated with excessive sex hormone production by an adrenocortical tumor in two dogs.

An 11-year-old spayed female Labrador Retriever and a 9-year-old castrated male miniature Poodle were evaluated because of clinical signs of hyperadrenocorticism. Cortisol testing did not support a diagnosis of hypercortisolemia in either dog; however, imaging studies revealed unilateral adrenal tumors in both dogs. Serum concentrations of 17-hydroxyprogesterone, progesterone, and estradiol were high in both dogs, and androstenedione concentrations were also high in 1 dog. It is suspected that sex hormone secretion by the adrenal tumors in these dogs resulted in clinical signs of hyperadrenocorticism. Clinical signs and hormonal abnormalities resolved in the male dog after surgical resection of the tumor. There was no improvement in clinical signs after treatment with mitotane in the female dog, which died 2 months after diagnosis. Histologic evaluation confirmed the presence of adrenocortical carcinoma in both dogs.     

Hypercalcaemia associated with chronic lymphocytic leukaemia in a Giant Schnauzer.

A 7-year-old male Giant Schnauzer was referred with a history of severe vomiting, lethargy, weight loss, polydipsia and polyuria. Detailed investigations revealed leucocytosis with a marked lymphocytosis, mild non-regenerative anaemia, thrombocytopenia, hypercalcaemia and azotaemia. Circulating lymphocytes were small and well-differentiated, and the same lymphoid population was present in bone marrow. Chronic lymphocyctic leukaemia with associated paraneoplastic hypercalcaemia was diagnosed. Immunohistochemical staining of a bone marrow biopsy revealed a neoplastic B-cell line expressing CD79. The dog responded to therapy with prednisolone and chlorambucil for a period of 8 months.     

三种草坪草净光合速率和蒸腾速率的日变化特点研究

研究了在晴天的条件下，假俭草、细叶结缕草和地毯草净光合速率和蒸腾整编的日变化特点。结果表明：（1）假俭草和细叶绍缕草的净光合速率的日变化曲线均为双峰型，而地毯草为三峰型，3种草出现峰值的时间不同，均有明显的“午睡”现象，日平均净光全速率的大小顺序为俭草＞地毯草＞细叶结缕草；（2）假俭草和细叶结缕草的蒸腾速率的日变化曲线均为双峰型,而地毯草为单峰型，3种草出现峰值的时间有所判差别，“午睡”现象均不明显，日平均蒸腾速率的大小顺序为细叶绍缕草＞地毯草＞假俭草；（3）不同生态因子与3种草坪草净光合速率、蒸腾速率的相关程度均不相等。同种态因子与不同草坪草的净光合速率、蒸腾速率的相关程度也不一样。

Effects of Benzyl Adenine and Abscisic Acid on Grain Yield and Yield Components in Triticale and Wheat

Grain yield and yield components (grains per ear, grain weight, 1000-grain weight, ear weight, ear seed ratio and dry matter partitioning between ear and seed) were examined in a wheat genotype (PBW-343) with well-filled grains and a Triticale genotype (DT-46) with poorly filled grains (showing grain shrivelling) grown in pots. Six days after anthesis (DAA), benzyladenine (BA) @2 µg ear⁻¹ and abscisic acid (ABA) @4 µg ear⁻¹ were injected at the base of the mother shoot ear in both species. It was observed that, in both wheat and Triticale , BA increased the grain weight, grain number and partitioning of dry matter between ear and seed, whereas ABA decreased the grain weight, grain number and dry matter partitioning between ear and seed. However, these decreases were slower in Triticale than in wheat. BA treatment increased the grain dry matter accumulation, which in turn resulted in better filling of grains and increased the grain weight in both wheat and Triticale . The average grain weight of Triticale was lower than that of wheat. Thus, it appears that variation in grain weight between wheat and Triticale might be due to different availabilities of growth-promoting phytohormones such as cytokinins and assimilates.     

甘蓝型双低隐性核不育杂交种沪油杂1号的选育

沪油杂1号(原编号SH-19)是利用隐性上位互作核雄性不育系20118A育成的甘蓝型双低杂交油菜品种.20118A的育性由2对隐性重叠基因和1对隐性上位基因控制,基因型为aabbRfRf,临保系的基因型为aabbrfrf,恢复系的基因型为AA__或__BB__.沪油杂1号种子含油量42.43%,芥酸含量0.62%,硫甙含量24.23μmol/g.在上海市油菜区域试验中平均产量2 243.3kg/hm2,比双高对照汇油50增产11.9%,比双低对照沪油15增产3.8%;在上海市油菜生产试验中平均产量2 244.0kg/hm2,分别比对照汇油50增产33.6%,比对照沪油15增产15.9%.     

羊源链球菌的分群鉴定及多价灭活苗的研制

2000～2003年,从安阳、邯郸等6个地区采取280份羊的病料,从中分离到150株链球菌,对其中20株典型分离株进行了生化分群鉴定及兰氏分群A～G诊断试剂鉴定.结果表明,6个地区发生的羊的链球菌病主要由C群兽疫链球菌(7/20),D群(8/20),E群(2/20)引起.其分布无明显地域性.选择C、D、E群中各1株为菌种,制备多价链球菌灭活苗,通过免疫试验,保护率达92%以上,免疫期半年以上,疫苗4℃保存期1年以上,证明该灭活苗安全性好,免疫效果明显.     

辛亥革命前后张謇与袁世凯的交往

张謇与袁世凯的交往长达三十余年,他从最初的相识荐袁、拥袁合作、相互借重到后来的分离,张謇曾幻想依靠袁世凯实现自己“实业救国”的抱负,却以失败而告终。二人分分合合,充满波折的交往过程反映了中国近代资本主义发展的艰难与坎坷。
