The 20th century advent GLOBE VALVE of the sleeve valve 60's, 70's heavy use at home and abroad, and 80 years the introduction of the sleeve valve petrochemical plant accounted for a larger proportion of that time, many people think that the sleeve valve can replace a single, double seat valve, to become the second-generation products.

Being combining with products distribution in styrene oxidation, we propose the styrene epoxidation carry out with Ti metallacyclo intermediates, And at the same time Ti-ZSM-5 have properties both catalytic epoxidation and acid-catalysis, namely the skeletal Ti can catalyze styrene epoxidation to styrene oxide and the skeletal Ti and Al can provide Lewis acid site to cause the rearrangement of styrene oxide to phenylacetaldehyde rapidly, the solvolysis to glycols and the cleavage of C=C double bond. Ti-ZSM-5 can also provide Bronsted acid site simultaneously, which is also catalytic center for the solvolysis to glycols.

同时结合Ti-ZSM-5催化选择性氧化苯乙烯反应的产物分布结果，提出苯乙烯环氧化反应可能是通过金属有机环机理进行；Ti-ZSM-5同时具有催化环氧化和酸催化两种功能，其骨架钛可催化苯乙烯环氧化生成环氧苯乙烷，而骨架钛和骨架铝等可提供Lewis酸位使环氧苯乙烷迅速发生重排生成苯乙醛从而使其成为反应的主要产物，同时还可发生加成以及碳碳键的裂解等副反应：Ti-ZSM-5也提供Bronsted酸位，它也是生成加成产物的活性中心。

And There was no serious complication;②In the course ofinterventional therapy, Direct portal vein angiography demonstrated vena coronaria ventriculi(100%)andgastricveins(65.26%)andvenagastricaposterior38.43%, Angiography demonstrated venacoronariaventriculi communicate esophagus varicose veins, gastric veins and vena gastrica posterior communicategastric varicose veins. vena coronaria ventriculi had only a small percentage of double vein, about30.57%. The sites of vena coronaria ventriculi arising from the portal vein, splenic vein, portosplenic junction, were found in 52.06%、27.39%、20.55% respectively.③12 extrahepaticprotosystemic shunts were found in these patients. Include gastro-nephrosshuntof 3 cases, 7 caseswere splenetic- nephros shunt and 2 cases shown recanalization of umbilical vein .④The averageportal pressure before and after the procedure were 3.87±1.82kPa and 3.64±1.14kPa in 73patients, but to the time of rebleeding, it was 3.96±0.23kPa in the 11 cases.⑤There werethree kinds of variceal outcome: disappearance (54,low degree (19).⑥Spearman logisticanalyse and ANOVAtest shown liver function class, variceal degree of the splenic necrosis area,the blood direction in portal vein before operation and remain small collateral routes were thesignificant factors concerning outcome of varices.⑦The bleeding volume and portalhypertensive gastropathy are main risk factors of rebleeding.⑧The course of livercirrhosis is the risk factor of survival and extrahepatic portosystemic shunt , fine varices are thebeneficial factors to survival.⑨During all cases'followed-up data, the 1, 2, 3, 4, 5 yearcumulative survival rates and rebleeding rates were 17.81%, 28.77%, 38.36%, 43.84%, 47.95%and93.15%,91.78%,86.30%,83.56%,80.82%respectively. Conclusion The interventional disconnection treatment for liver cirrhosis and portalhypertension was designed suitability. It rapidlycontrol bleeding,butpressure of portal vein was notobvious high, perfusion was not low .it was compared with surgery therapeutic that interventionaldisconnection treatment was safe and had a significant clinical effect to hemorrhage and preventfrom rebleeding.

METHODS: CNE-2 human nasopharyngeal carcinoma cells were exposed repeatedly to γ-rays and then screened for a new radioresistant subline named CNE-2R. Double times of CNE-2 and CNE-2R cells were determined by MTT assays. The relative radiosensitivities of tumor cells were assessed by standard colony formation assays. Survival rates after exposed to irradiation were measured by MTT assays. The time courses of cell cycle distribution before and after irradiation were investigated by flow cytometry.

She is a typical "charming chinese old-style woman" who accepted a little "new education".through our analysis,we can find when she was giving in to her husband,she wanted to react against him inside of her;she loved her son ,but she took all she could do to let him give up his true love at the same time; she did pursue her love,but meanwhile shed rather let herself be in chains in this rich family and play a painful role between "mother" and "lover"; she looked down up working-class people ,but meanwhile she commiserated working-class women.all above,prove that fan is a double-personality female.she could stand for all contemopany chinese young women who were influenced by "new education": lovely but unreasonable.the author of "the thunder storm" expressed how contemopany chinese young women should face the challenge from life through creating her.meanwhile,it can prove the value of "the thunder-storm".

她是1个具有特殊魅力的"中国旧式女人"，同时又是受了点"新式教育"影响的女性。她是1个有着双重性格的女子。她对丈夫既表现出软弱地屈从又表现出怨恨和反抗；她既关爱儿子又要以世俗的等级观念来干涉儿子的感情；她敢于追求自己的爱情却又把自己束缚在1个狭小的空间；她鄙视下等人的生活同时又对处于社会底层的女性表现出真诚的同情。蘩漪是54时期中国青年知识女性的1个时代缩影。通过对她的分析，我们可以看到特定时期中国知识女性的可爱之处以及时代赋予给她们的缺陷，从而进1步阐述当代中国女性应该以什么样的姿态站在人生的舞台上，也更进1步确定了《雷雨》所具有的社会价值和时代意义。
