The other was observative group of 98 cases,which aceordring to the graph method,calculate the length of the pipe. Then using SPSS 10.00 soft,analysed the data. Results The distance compared the end of the stomach pipe and the point of the middle of the stomach body,the observative group was（- 1.12 ± 1.36） cm,the was 1.31 -5. 6cm. The length in observative group was longer than thatin contrast group , and the variability was minlmum.

国内还有应用胃镜直视测量不同身高患者的门齿至胃粘液池的长度来判定成人置人胃管的长度，但不能代替鼻孔至胃底的长度，为了准确的置人胃管深度，以达到最佳的吸引位置，我们通过由开腹手术医生确认胃管进入胃体中段的最佳长度，再测量胃管长度的方法，对2O0例开腹手术患者胃管长度的比较分析得出，根据英国Scalzo 所提出的图表法鼻胃管插入长度=6.7+[0.26 身高] 』。

Chitosan had been modified by polyacrylate sodium, glularaldehyde, and NaBH4, respectively, which afforded three kinds modified chitosan: polyacrylate sodium modified chitosan (CIS- PA4) chitosan bead and pentamethylene diamido crosslinked chitosan bead (CTSB- G- Hy). The adsorption properties of CTS-CTSB and CTSB-G-Hy were studied by L25(56) orthogonal experimental design. They show high adsorption activities for Pb2+ in solution. The highest removal efficiency of Pb2+ for CTS-PA4, CTSB and CTSB-G-Hy is 94%, 96% and 93%, respectively. The results showed the adsorption property of CTSB is the highest. The CTSB- G- Hy has good mechanical property, acid-resistance and alkali-resistance.

第二部分壳聚糖的改性及其对水溶液中铅离子的吸附性能研究以壳聚糖为原料制备了三种改性吸附剂——聚丙烯酸钠改性壳聚糖(CTS——PA_4)、珠状壳聚糖凝胶树脂和戊二氨交联珠状壳聚糖凝胶树脂，着重考察了CTSB—G—Hy的制备条件，并考察了三种吸附剂吸附6.3mg/L铅离子水溶液中铅的最佳使用条件，结果表明对CTS—PA_4而言当pb~(2+)溶液的pH在4～6.5之间，吸附剂用量为5g/L，吸附时间为1h时pb~(2+)去除率高于94％，CTS—PA_4可在酸性条件下使用，在碱性条件下依然有效但处理效果较差；CTSB对pb~(2+)具有很好的吸附能力吸附剂用量为5g/L，吸附时间为1h时处理效果极佳，pb~(2+)去除率高于96％；CTSB—G—Hy对pb~(2+)具有一定的吸附能力，吸附剂用量为3g/L，吸附时间为1.5h时处理效果最佳，Pb~(2+)去除率高于93％，而且CTSB—G—Hy的机械强度高，耐酸碱性强，可在较宽的pH范围内使用。

From the experiment discovered for the first time the dimethyl ether may substitute CO to take the chain-carrying agent of the peroxy free radical chemistry amplifier system, and optimized the CH_3OCH_3-NO-HO_2 chemistry amplifying system determination condition, the CH_3OCH_3 best density is 1.876 ppmv, the NO best density is 1.3ppmv, and obtained this method chain length CL=124, 5 parallel determinations densities of HO_2 are the 44.0pptv, the relatively standard deviation is smaller than 4%; Although chemistry box model computed result indicated the dimethyl ether, the ethene, the propene and the ethanol all can take the chain-carrying agent of the peroxy free radical chemistry amplifier system, and their simulation chain length all grows up compared to the CO-NO-HO_2 chemistry amplifying systems, but experiments proved the ethene, the propene and the ethanol have not suit the chain-carrying agents.

首次从实验上发现二甲醚可以替代CO作为过氧自由基化学放大系统的链传递试剂，并优化了CH_3OCH_3-NO-HO_2化学放大系统的测定条件，CH_3OCH_3的最佳浓度是1876ppmv，NO的最佳浓度为1.3ppmv，并得到了这一方法的链反应长度(CL=124)，5次平行测定浓度为44.0pptv的HO_2自由基，相对标准偏差＜4％；虽然化学盒子模式计算结果表明二甲醚、乙烯、丙烯和乙醇都能作为过氧自由基化学放大系统的链传递试剂，并且它们的模拟链长都比CO-NO-HO_2化学放大体系的链长大，但是实验证明乙烯、丙烯和乙醇不适合作为过氧自由基化学放大系统的链传递试剂。
