研究了噻葸、葸、及17％噻蒽和83％蒽混合物的炭化(525℃)和石墨化(2500℃),噻葸炭化后生成密度较低的非石墨化炭。1200～2500℃热处理时,由于硫的不断逸出,闭气孔率增加,引起密度进一步下降。混合物炭化后生成可石墨化炭,与葸在同样温度下的炭化物具有相同的晶体参数,但与蒽的炭化物相比,混合物的炭化物在热处理过程中密度下降比较明显,硫含量的减小主要发生在1400～1600℃。密度的变化似乎是由于微晶顺序的破坏使得直径小于2000A的开气孔的体积增加而产生的。混合物炭化产物和所报道的高硫石油焦类似,在石墨化过程中产生不可逆膨胀(晶胀)。

用噻蒽和蒽的混合物研究了添加Fe2O3对热处理时硫逸出引起的炭体积膨胀的抑制效果。没有添加剂时,炭的密度大约在1200℃以上时开始减小,并持续到2500℃。伴随此过程硫的含量在1400～1600℃急剧减小,加入Fe2O3后,硫含量在整个实验温度范围内都较高。在1200～1600℃炭的密度稍有增加,而在1600～2500℃,其密度不断减小。1600℃以下,在冷却的反应混合物中检测到硫化铁,这与热处理过程中,铁—硫液相的存在相符合,液相似乎是通过改变硫逸出的机理而影响密度的变化。虽然在更高的温度下,FeS已不明显,但铁化合物的存在似乎有减小膨胀的作用。添加剂Fe2O3不影响晶体的生长和石墨化过程向有序结构的发展。炭密度的减小（有或无添加剂时）可归因于晶体排列的破坏。气孔率的测量表明微孔体积的增加是由于形成了直径小于2000（?）的微孔所致。

在InGaN发光二极管中 ,尽管存在着大量的位错 ,但其效率还是相当高的。用InGaN作为有源层是很重要的。在InGaN基LED的情况下 ,为产生光发射需要较高的激发功率。横向大面积外延生长的GaN激光二极管 (LDs)是在厚的GaN衬底上外延制备成的。在温度 2 5 0℃、30mW输出的连续工作状态下 ,其工作电流小于 4 2mA ,6 0 0℃、30mW输出的连续工作状态下的寿命约为1 5 0 0 0小时。这些结果表明 ,螺旋位错密度的降低延长了激光二极管的寿命。此外 ,良好的散热也是很重要的。

To accurately assess the prevalence of GERD symptoms in general practice. METHODS： 4139 consecutive patients （2025 men and 2114 women with a mean age of 43 years）, who first attended the Outpatient Department of General Medicine and Emergency Care at Toho University Omori Hospital, were asked to respond to the F-scale questionnaire regardless of their chief complaints. The questionnaire is a self-report instrument, written in a simple and easy-to- understand language, containing 12 questions. RESULTS： Of 4139 subjects, 1554 patients （37.6%） were identified as GERD according to their F-scale score （〉 7）. However, there were only 45 consultations （1.1%） for typical GERD symptoms. Although GERD symptoms are common in adults of all ages, the prevalence of GERD was highest in the 20-29 years age group and the age group 70-79 years had the lowest prevalence for both males and females. CONCLUSION： Although there was a high rote indicating GERD in our primary care population, only 1.1% of outpatients attended our hospital with a chief complaint of GERD symptoms. Since about one-third of GERD patients are affected by atypical symptoms, general physicians need to be cautious about extrapolating these results to patients with a chief complaint other than typical GERD *** T, Urita y, sugimoto M, Miki K.

We present a case of Cronkhite-Canada syndrome(CCS) in which the entire intestine was observed using a prototype of magnifying single-balloon enteroscope(SIF y-0007, Olympus). CCS is a rare, non-familial gastrointestinal polyposis with ectodermal abnormalities. To our knowledge, this is the first report showing magnified intestinal lesions of CCS. A 73-year-old female visited our hospital with complaints of diarrhea and dysgeusia. The blood test showed mild anemia and hypoalbuminemia. The esophagogastroduodenoscopy and colonoscopy revealed diffuse and reddened sessile to semi-pedunculated polyps, resulting in the diagnosis of CCS. In addition to the findings of conventional balloon-assisted enteroscopy or capsule endoscopy, magnifying observation revealed tiny granular structures, non-uniformity of the villus, irregular caliber of the loop-like capillaries, scattered white spots in the villous tip, and patchy redness of the villus. Histologically, the scattered white spots and patchy redness of the villus reflect lymphangiectasia and bleeding to interstitium, respectively.

AIM To examine the influence of night duty(ND) on endoscopic therapy for biliary duct *** The subjects consisted of 133 patients who received initial endoscopic therapy for biliary duct stones performed by eight endoscopists after they had been on(ND group, n = 34 patients) or not [day duty(DD) group, n = 99 patients]. Patient characteristics(age, gender, history of abdominal surgery, transverse diameter of the largest stone, number of stones), years of experience of the endoscopists, endoscopic procedures [sphincterotomy, papillary balloon dilation(EPBD), papillary large balloon dilation(EPLBD)], and outcomes of initial endoscopy(procedure time; rate of stone removal by the first endoscopist; proceduresuccess rate by the first endoscopist: removal of stones or endoscopic retrograde biliary drainage; rate of final stone removal; final procedure success rate; complications; hospitalization after the procedure) were compared retrospectively between the two groups. History of abdominal surgery and treatment outcomes were also compared between the groups for each of the four endoscopists who performed most of the procedures in the ND *** There were no significant differences regarding the number of treatments performed by each endoscopist or the years of experience between the ND and DD groups. The frequency of endoscopic retrograde cholangiopancreatography procedures did not differ significantly between the groups. There were also no significant differences regarding patient characteristics: age, gender, history of abdominal surgery(ND 7: Billroth II 4, R-y 3; DD 18: double tract reconstruction 1, Billroth I 3, Billroth II 6, R-y 7, duodenoduodenostomy for annular pancreas 1), transverse diameter of largest stone, and number of stones between the two groups.
