硬

The goal is to design systems that can transform themselves from hard to soft and from soft to hard, upon command.

目的是设计一种能够根据指令，由软到硬，又由硬到软的改变自身形态的系统。

According to the proposed mechanism, the hard agglomerates were mainly formed during the drying of the hydroxide gels.

提出了新的氧化锆粉末硬团聚体形成机理，据此可以说明，硬团聚体主要在凝胶的干燥过程中形成。

The hard outer shell is made out of hard plastic and is usually closed using buckles or ratchet bails.

硬外壳是由出硬塑料，通常是封闭使用扣或棘轮保释。

Theepidural stimulation test was performed after catheter placement,after local anesthetic boluses, and during epidural analgesia,up to six times in each patient.

分别在导管置入后、局部麻醉药推注后、硬膜外镇痛过程中，对每位病人进行最多6次的硬膜外刺激试验。

Deng's stamina is a wonder; cleaning out these ditches would be hard work for any man, so it's no wonder she gets blisters and callouses. But she doesn't object, because - as she says - the callouses give her protection.

长茧会好，好了又长，都这样子，像这个很硬，老茧的手有时候很硬，我都会拿剪刀剪平，有时候它也是一种保护，因为我都不需要担心烧伤。

The soft layer of ECC media usually possesseshigh saturation magnetization and also high demagnetizing energy density.

ECC介质由交换耦合的软磁层与硬磁层构成，它是通过软磁层与硬磁层的磁矩在磁化反转过程中的非一致转动来达到降低矫顽力的效果，而无外场时热反转仍为一致转动，因而能保持较高的热稳定性。

You need to know whether the toy can be used on hard surface only or both hard surface and grasses.

你需要知道的玩具可用于硬表面的唯一或硬表面和草。

The hardness of HSS roll was over 66 HRC, the depth of hardened layer excesses 30 mm, the variation of hardness in the roll surface was smaller than 1.5 HRC, and the wear resistance of HSS roll was better than that of high chromium cast iron roll and high nickel chromium indefinite hilled cast iron roll, close to that of powder metallurgy hard alloy roll.

研制出的高速钢轧辊硬度超过66HRC，淬硬层深度超过30mm，辊面硬度差小于1.5HRC，耐磨性优于高铬铸铁和高镍铬无限冷硬铸铁轧辊，接近硬质合金轧辊。

In order to gain a better understanding of coupled thermo-hydro-mechanical processes in indurated clays being considered in various countries as host rock for the disposal of high-level radioactive waste,a heating experiment named HE-D is being conducted on the Opalinus clay at the Mont Terri Rock Laboratory in Switzerland.

为深入理解硬泥岩在热–水–力耦合作用下的变化特征，在瑞士的 Mont Terri 地下岩石实验室对 Opalinus 硬泥岩进行了现场加热试验。

Purpose: 1.0x0.4cm laminectomies were performed in 8 healthy adult rabbits at L3 and L5. One of the defeats was left alone as control,the other defect was covered with Fibrin Glue.The FG was polymerized to be stable membrane after 3-5 minites. The animals were sacrificed in 4 weeks after the operation.

目的：本实验选用健康成年白兔8只，在L3、L5部位切除椎板形成两处1.0X0.4cm缺损，一缺损作为空白对照，另一缺损在硬膜外喷洒医用生物蛋白胶（Fibrin Glue，简称FG），FG于3-5分钟后聚合成为稳定的薄膜覆盖于硬脊膜上。

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%.
