The utilization of the 1981 IRRDB Hevea germplasm is very slow in China. For further characterization and evaluation of the germplasm, an analysis was made to evaluate the characteristics of latex regeneration and latex flow of the new Amazon Hevea germplasm by the method of latex diagnosis. Nine accessions of the germplasm were determined in terms of physiological parameters such as yield, initial flow rate, plug index, sucrose, thiols, phosphorus, magnesium, etc, with RRIM600 as the control.

我国橡胶树新种质创新利用进展缓慢，为了深入全面的鉴定橡胶树新种质，加速其利用进程，笔者采用胶乳诊断方法，测定分析了1986年定植于大田鉴定评价圃的14份橡胶树新种质与产排胶密切相关的干胶含量、干胶产量、排胶初速度、堵塞指数及胶乳硫醇、无机磷、蔗糖及镁离子含量等生理参数。

Re-puncturing were related to factors such as patient of incoordinate, fluid exudation, skills of puncturing,family members, and needle obstruction etc. Suggested that nursing staff pay attention to the explanation to patients and

重新穿刺的原因与患儿不合作、液体渗出、家属因素、技术因素、血液堵塞等因素有关，提示护理人员要做好患儿及家属的解释工作，取得患儿及家属的配合，必要时适当使用镇静剂，以减少重新穿刺率。

During in recent years, most of oil-wells are severely undergoing blockage by asphaltenes and other organic depositions when the exploitation of Ta'he oil field goes into middle period. These situations take much trouble for operation and cause the increasing of operating sequence and cost.

近年来塔河油田8区及外围轻质油井随着塔河油田开采进入中期，各区块的油井出现了严重的沥青质和蜡等有机沉淀的堵塞情况，给作业带来很大难度，作业工序及作业费用增加。

According to the problems appeared in the sets of FGD, such as the pressure's instability in the boiler and special erosion, incrustation, abrasion, and jam in FGD set itself, the paper analyzed causation of the problems and made the operation and maintenance rules.

The conclusions can be drawn through numerical simulation: The hydrate-forming region becomes small with increasing circulation rate and inhibiter concentration, and it is possible to make the hydrate-forming region away from sea floor by increasing circulation rate and inhibiter concentration, thus preventing blowout preventer lines from hydrate plugging; the decrease in gas volume fraction in the annulus due to hydrate formation reduces pit gain, which can delay the detection of well kick; the possibility of hydrate presence at a relatively low gas production rate is much greater than that at a relatively higher production rate; the bottom hole pressure is affected little by hydrate phase transition, and it is allowable not to consider hydrate phase transition when the bottom hole pressure is calculated; shut-in casing pressure cann't truly reflect gas kick due to hydrate formation and the situation is getting worse with time

模拟计算结果表明：溢流期间，天然气水合物的生成区域会随着循环流量的增大或抑制剂浓度的提高而减小，可通过增大流量和抑制剂浓度使水合物的生成区域脱离海底，减小防喷器管线被堵塞的危险；水合物的生成使环空中气体体积分数降低，泥浆池增量减小，给溢流检测带来延迟；当检测到有气侵发生时，水合物藏分解速率比较小时，井筒中生成水合物的可能性要比分解速率大的情况下更为严重；水合物相变对井底压力的影响较小，在工程中计算井底压力时可以忽略；由于天然气水合物的生成使得关井套压值不能真实反应气侵情况，而且随着时间的增加情况会更加严重。
