In acid pulp, the depressing abilities of reagents on diaspore are in the order of hydroxamic acid starch＞dialdehyde starch＞carboxymethyl starch＞cationic starch＞primary starch. In addition, hydroxamic acid starch and carboxymethyl starch can activate kaolinite without influence on the recoveries of pyrophyllite and illite, so the two reagents have great potential and prospect to be the depressant of diaspore and the activator of kaolinite in bauxite reverse flotation.(3) By oximation of the copolymer of acrylamide and methyl acrylate, hydroxamic acid polyacrylamide is synthesized.

3对丙烯酰胺和丙烯酸甲酯的共聚物肟化制得氧肟酸聚丙烯酰胺，将它同非离子聚丙烯酰胺、阴离子聚丙烯酰胺、阳离子聚丙烯酰胺和两性聚丙烯酰胺分别应用于四种矿物的单矿物浮选试验，结果显示，改性聚丙烯酰胺对一水硬铝石、高岭石和伊利石均具有活化作用，其中，药剂对高岭石的活化最强，使它的回收率在整个pH值范围达到80％左右，在一定pH条件下超过一水硬铝石的回收率，解决了高岭石难浮选的问题。

The paramedian as opposed to midlineneedle approach and smaller epidural needle or catheter gaugesdo not reduce the risk of epidural vein cannulation.

以下两种策略未能降低误置入硬膜外静脉的风险：旁正中进针穿刺法相比中线进针法和采用较小号硬膜外穿刺针或导管。

After a while later, Draco feels himself kind of horny and open his eyes to have some pawing, but then he eventually realize why he is horny.

过了一会， Draco 突然感到自己好象硬了起来，然后他便睁开眼睛摸索著，然而他最终发现让他硬起来的原因了。

Results CT findings of six cases are: cerebral hemorrhage were 2 cases ,subdural pneumatosis 6 cases, subdural hemorrhage 3 cases, cerebral edema 2 cases.

结果 6例病人CT表现为血肿再发2例，硬膜下积气6例，硬膜下出血3例，脑水肿2例。

The metabolic and endocrine sequelae of intrafacetal depot steroids have not been studied, but extrapolating from epidural steroid injections, one would expect suppression of the hypothalamic–pituitary–adrenal axis lasting up to 4 weeks depending on the depot steroid used, and impaired insulin sensitivity manifesting as elevated glucose levels for less than a week.251,252 Although rare, a host of infections have been reported after intraarticular injections including septic arthritis, epidural abscess, and meningitis.253–255 Case reports of spinal anesthesia and postdural puncture headache have also been published.256,257

小关节间隙类固醇滞留所产生的代谢和内分泌作用也未见研究，但是从硬膜外类固醇注射可以推知，依据使用量的不同，其抑制下丘脑-垂体-肾上腺轴的时间可以持续4周。很多报道显示关节内注射后可以发生感染，但发生率较少，包括脓毒性关节炎，硬膜外脓肿及脑膜炎。也可见关于脊髓麻痹及穿刺后疼痛的报道。

Test results show that the shear strength parameters of the fly ash with high calcium oxide content can make a notable change due to pozzolanic action and frost and thaw cycles, but for the fly ash with low calcium oxide content this phenomenon is not very obvious,and the influence of the frost and thaw cycles can be neglected.

试验结果表明，高氧化钙含量的粉煤灰的强度指标受上述两种作用的影响显著；低氧化钙含量的粉煤灰的强度指标在凝硬作用下也有所提高，但基本不受冻融作用的影响；干贮粉煤灰的渗透系数受凝硬和冻融作用的影响较小。

The experimental results show that these curves were verified to be suitable for prediction of hardened pozzolanic concrete strength with a measured UPV value.

实验结果显示，选用配比之56天硬固预估强度与实际抗压强度间的误差有99%在±15以内，所以混凝土添加卜作岚掺料后，利用先前针对普通混凝土建立之公式推估卜作岚混凝土硬固后抗压强度是可行的。

objective to explore some ct characteristics and risk factors for traumatic chronic bilateral subdural hematoma.methods a total of 52 patients with chronic subdural hematoma were reviewed.some ct characteristics of bcsdh were studied first.then,the risk factors for bcsdh were determined by logistic regression model from the following variates: age,gender,prediagnostic duration,site for injury force,coma experience and ct showing after injury.results bcsdh was observed in 44.2% of 52 patients with csdh.

作者单位：第三军医大学大坪医院野战外科研究所神经外科，重庆 400042 目的探讨创伤性双侧慢性硬膜下血肿的ct特征及危险因素。方法回顾有随访资料的创伤性慢性硬膜下血肿52例。先研究其ct表现，然后采用多因素logistic回归分析从以下变量中，如年龄、性别、伤后&潜伏&时间、受伤着力部位、受伤时有无昏迷经过、伤时ct表现等确定bcsdh发生的影响因素。

Gestational hypertension is a common disease. Continue epidural anaesth during caesarean section is effective and safe for puerperant and infant.

妊娠高血压疾病是孕产妇常见病之一，行剖宫产麻醉应首先选用持续硬膜外麻醉，麻醉中无麻醉并发症发生，术后可在硬膜外腔内持续用镇痛药物，解决术后患者疼痛，其方法为安全适宜，麻醉平面易控制，对母婴影响小，并发症少等优点。

Results There was significant differencePConclusion The dynamic change of reticulin myelofibrosis content in bone marrow can be an important reference for the efficacy and early sign of recurrence in acute leukemia.

结果 16例急性白血病患者治疗前后骨髓网硬蛋白纤维阳性例数有明显差异P结论骨髓网硬蛋白纤维含量的动态变化，可作为急性白血病患者判定疗效与预测早期复发的一个重要参考指标。

Breath, muscle contraction of the buttocks; arch body, as far as possible to hold his head, right leg straight towards the ceiling (peg-leg knee in order to avoid muscle tension).

呼气，收缩臀部肌肉；拱起身体，尽量抬起头来，右腿伸直朝向天花板（膝微屈，以避免肌肉紧张）。

The cost of moving grain food products was unchanged from May, but year over year are up 8%.

粮食产品的运输费用与5月份相比没有变化，但却比去年同期高8％。
