Results The ethanol extracts 0.48 gkg^(-1, macroporous resin eluate of aqua 0.3 gkg^(-1 and the further purification 0.1, 0.3 gkg^(-1 could hasten gastric emptying in mice. Furthermore, they restrained the inhibition of dopamine on gastric emptying in mice. They had no effect on the inhibition of atropine.

结果 醇提物0.48gkg^(-1、大孔树脂水洗脱物0.3gkg^(-1及继续纯化物01、0.3gkg^(-1对正常小鼠的胃排空有促进作用，并可拮抗多巴胺引起的小鼠胃排空的抑制作用，而对阿托品引起的小鼠胃排空抑制作用无影响。

Really do not leak, however there is still a long way to go, such as magnetic separation pump shield pump kits and sets the life of screening questions, materials, pitting the problem, question the reliability of static sealing and so on.

Even if the face that looks very clean, also be unavoidable to meet in nose ala two side discover a few hide inside wool stoma, the dirty stuff that squashs to be able to run a bit, generally speaking resembles such state, and its periphery does not have roseola condition, we are what these troublesome dot say " acne ".

即使是看起来很干净的脸，也免不了会在鼻翼两侧发现一些暗藏在毛细孔内，稍一挤压就会跑出来的脏东西，一般而言像这样的状况，且其外围并无红疹状态，我们将这些麻烦的小东西称之为「粉刺」。

Moreover, based on the uniformity of solid axial distribution, the respective performances of the radiant orifice gas distributor and the perforated plate （1 mm） were compared, as well as with and without internals.

Abstract］ objective to assess the efficacy and safety of transurethral resection of prostatewith plasmakinetic technique and to improve the qualities of pkrp.methods the data of 273 patients with benign prostatic hyperplasiawere retrospectively studied baseing on the mastering of pkrp.the average maximum urinary flow rate,the average residual urinary volumeand the average international prostate symptom score were analysed.results pkrp was successfully performed on 273 patients.intraoperative blood transfusion was performed in 6 cases,no obturator nerve reflex,transurethral resection syndrome,permanent urinary incontinence occurred and no death cases occurred.the follow-up time was 2～26 months with an average of 5.63 months,postoperative average qmax increased to 15.9 ml/s,and ruv decreased to 16.0 ml/s and the average ipss was 9.compared with those of preoperation,the differences were significant.conclusion pkrp has superior tissue cutting function and hemostasis.it is suggested that transurethral bipolar plasmakinetic resection of prostate be effective and safe.

目的 探讨经尿道双极等离子前列腺切除术的安全性与有效性，提高pkrp质量。方法回顾性分析273例良性前列腺增生患者pkrp资料，比较手术前后最大尿流率、膀胱剩余尿量及国际前列腺症状评分。结果 273例手术均顺利完成，术中输血6例，无闭孔神经反射、永久性尿失禁、经尿道电切综合征及死亡病例，随访2～26个月，平均5.63个月，qmax平均增至15.9 ml/s，ruv平均降至16.0 ml，ipss平均9分。与术前相比，各项指标均有明显改善。结论 pkrp具有良好的组织切割功能及可靠的止血作用，治疗bph安全有效。

Porous sorbent with high adsorption capacity was able to be produced by pyrolyzing at 400—600℃ in N_2 for 2.8h and activated with CO_2 at 870℃ for about 3.0h.

即炭化温度在400-600℃之间，炭化时间为2.8h左右，温升速率较低的条件下无氧炭化后所得的样品，再经过870℃环境下在CO2中活化3.0h，可得内孔发达、对SO2吸附能力很强的吸附剂。

In the present invention, platinum-carbon catalyst, perfluoro sulfonic acid resin solution and absolute ethyl alcohol are uniformly mixed under ultrasonic conditions; mixture is uniformly smeared on a micro-porous layer of carbon cloth or carbon paper in a brushing or printing method, and a traditional Pt/C gas porous electrode is obtained after drying; silicon oil is adopted to infiltrate into pores of a catalyst layer and a diffusion layer of the traditional Pt/C gas porous electrode, and then the ordering anti-drowning gas porous electrode is obtained after drying.

本发明是将铂碳催化剂、全氟磺酸树脂溶液和无水乙醇在超声波条件下混合均匀，采用涂刷或印制的方法将混合物均匀涂布到碳布或碳纸的微孔层上，干燥后制得传统Pt/C气体多孔电极；然后将硅油渗入到传统Pt/C气体多孔电极的催化层和扩散层孔隙中，干燥后制得有序化抗溺水气体多孔电极。
