目的检测和评估手传振动企业的手传振动危害,初步分析手传振动作业工人冷水复温率的影响因素。方法以广东省五家企业的接振工人为研究对象,现场检测振动接触水平,测定冷水复温率。通过问卷调查,了解不同岗位接振工人的一般情况。分析性别、年龄、吸烟、饮酒、高血压、接振剂量、不同岗位与冷水复温异常率的关联。结果所检测的48个接振岗位操作中有31个岗位的振动水平A(4)超过我国国家标准规定的5 m/s2,超标率64.6%。按国际上A(8)的分级标准,有28个点达到或超过Ⅰ级危险度。经单因素χ2检验,年龄、吸烟指数、高血压、接振剂量对冷水复温异常影响的差异有统计学意义(P均0.05)。Logistic回归分析发现,年龄≥40岁与冷水复温率关联的比值比(OR)=1.865(P0.05)。吸烟指数600与冷水复温率关联的OR=2.474(P0.05)。高血压与冷水复温率关联的OR=1.231(P0.05)。饮酒指数≤600与冷水复温率关联的OR=0.395(P0.05)。中剂量组、高剂量组与冷水复温率的关联的OR值分别为1.232、2.135(P均0.05)。结论所调查的企业手传振动危害严重。年龄、吸烟、高血压是影响冷水复温率异常的危险因素,饮酒指数≤600是保护因素。接振剂量与冷水复温异常无明显相关。

Objective To assess the hand-transmitted vibration hazards and roughly analyze the affecting factors of cold water rewarming rate among workers exposed to the hand-transmitted vibration. Methods The workers exposed to hand-transmitted vibration from 5 companies in Guangdong Province were studied. The vibration levels and cold water rewarming rates were measured. The general information,including working history and personal status,were collected with the questionnaire. The correlation between gender,age, smoking, drinking, hypertension, dose of vibration,different positions and the abnormal rate of cold water rewarming was analyzed. Results Vibration levels A (4) were detected in 48 operating sites and 31 of them were not compliant with the national standard of 5 m/s2. Compared with the international A (8)grading standards,28 operation sites were ranked as ones with grade I (or high) risk. Single factor chi-square analysis showed that the abnormal cold water rewarming was significantly

以新玉15号为供试品种，研究了春播和麦后复播青贮玉米（复播1期，6月30日播种；复播2期，7月10日播种）在产量、干物质积累和光温气候资源利用等方面的差异。结果表明：春播、复播1期、复播2期的群体干物质产量分别为15615、17615、14671 kg·hm－2，春播、复播1期、复播2期鲜重产量53988、67251、68327 kg·hm－2；复播青贮玉米生育期明显缩短，光合有效辐射和≥10℃积温较春播少；复播1期苗期、穗期、灌浆期均处于最适温度范围之内；春播、复播1期、复播2期的 LA I峰值为5．01、5．72、6．36，总光合势分别为2．45×106、2．84×106、3．37×106 m2·d－1·hm－2。复播青贮玉米的产量潜力主要在于大口期之前生育期优越的光温资源条件，且大口期之前干物质积累速率较春播快。

Obj ective:To probe into the influence of different rewarming time on immune function of liver cancer patients complicated with hypothermia af-ter hepatectomy.Methods:A total of 90 cases of hypothermia patients were randomly divided into 3 groups according to the rewarming time:A group( 60min),30 cases in each. The plasma IL 2 and IL 6 were measured on preoperative and postopera-tive 1st,2th day;and T lymphocyte subsets(CD3+,CD4+,CD8+,CD4+/CD8+) were measured on preoperative and postoperative 1st,5th day.Results:CD3+,CD4+ on the 1st day after operation and CD4+/CD8+ on 5th day were the lowest in group C(P 0.05).On the postoperative 1st and 2th day,IL 2 was the lowest in group C;IL 6 was the highest in group C on the postoperative 2th day (P<0.05).There was between group effect in IL 2,the between group effect,time effect and interaction effect in IL 6 P<0.05.Conclusion:The rewarming time was longer than 60min,which would delay the recovery of immune function.Early postoperative effecti

采用半水磷石膏与无水磷石膏复配制备复相磷石膏胶凝材料,通过测试复相磷石膏的凝结时间、强度性能和水化温升,结合X射线衍射(XRD)和扫描电镜(SEM)技术研究复相磷石膏水化硬化特性。结果表明,半水磷石膏激发无水磷石膏水化,使其水化放热加快,凝结时间缩短;无水磷石膏延缓半水磷石膏凝结硬化,凝结时间延长,水化放热减缓;与纯半水、无水磷石膏相比,复相磷石膏晶体形貌致密程度高,孔隙率低,硬化体强度较好。

The hydration and hardening characteristics of duplex phosphogypsum(DPG) prepared by hemihydrate phosphogypsum(HPG) and anhydrite phosphogypsum(APG) were studied through investigating the setting time, strength properties and temperature rise of hydration and by analyzing the XRD spectrum and SEM graphs of the prepared DPG. The results show that APG was activated by HPG, and the heat evolution was accelerated. And the hydration of HPG was retarded by APG, leading to retardation of the heat evolution. Comparing with pure hemihydrates or anhydrite phosphogypsum, the duplex phosphogypsum binder has higher compactness of crystal morphology, lower porosity and better strength of hardened paste.

从阴阳二气，阳主阴从；阴阳二气，尤重阳气；阳气之中，肾阳为本；易损难复，惟此阳气；治寒以热，温补阳气；阳虚易辨，阴火难识6方面小结王自立主任医师独特的学术思想，指出对于阴阳二气，尤重阳气，因为阳主阴从，阳气之重要，犹如太阳与天体的关系，不可或缺，是生命的根本和动力，但其特性却是难得而易失，易失而难复，故临证之际时时顾护阳气，形成了独特的温阳思想。

Chief physicianWangZili′sunique academic thinking is summarized from principalYangand subordinateYin,Yangas the major part; kidneyYangas the root,Yangbeing easily damaged, treating cold with heat, warming and invigoratingYang;Yangdeficiency could be easily differentiated,Yinfire is hard to distinguish, he points out thatYangshould be taken as the major part inYin-Yang, since principalYangand subordinateYin, Yangas the important one, are just like the relationship between the sun and celestial bodies, indispensable, they are the root and the power of the life,Yangis difficult to obtain and easy to lose, therefore, he attendsYangwhen he treats the patients, he has formed his uniqueYang-warming thinking.
