确定北部高压变泥质岩石，早期矿物组合为石榴子石+富镁硬绿泥石+多硅白云母+石英±蓝晶石±文石或石榴子石+富镁硬绿泥石+多硅白云母+钠云母+石英，对应的温压条件为550±30℃和1.4～2.0GPa；晚期矿物组合为白云母+绿泥石+石英±钠长石，经受了绿片岩相的退变质作用，其温度小于550℃，压力低于0.6GPa。

The longer the soft segments the better the mobility of the softsegments, and the better the crystallizability of the soft segments.

当软链段分子量超过6000后，软链段结晶的完善程度虽然比均聚物差，但结晶能力对硬链段含量的变化已不敏感，其结晶所需过冷度、熔点和熔融热焓在所考察的硬链段含量范围内基本保持不变。

Vopt is a disk defragmenter that includes batch and scheduled defragmentation options to keep your disk performance at an optimal level and can show information and statistics for file usage, fragmentation, and more all combined in a visually rich yet compact environment. It offers advanced features to override NTFS packing style, exclusion of large files and specific paths, as well as strategic placement of file to improve defragmentation speed.

硬 盘长时间安装软件或者删除文件变的凌乱，这样不仅硬盘存取资料速度变慢也会影响系统效率，虽可以利用Windown内附的磁盘整理程序来整理硬盘，但速度并不是很快，想找其它Windown用的磁盘整理程序取代，Vopt可将分裂在硬盘上不同扇区的文件快速和安全的重整，帮你节省更多时间。

This algorithm was realized by minimizing the invariant ellipsoid of the closed loop system. Some sufficient conditions dependent on the invariant set for the satisfaction of the time domain hard constraints were also derived.

在系统初始状态小于某个界的情况下，将性能输出的能量作为优化的性能指标，通过最小化系统的不变椭圆域来实现系统优化控制，同时得到依赖于该不变域的满足时域硬约束的充分条件。

But these first rubber overshoes and raincoats were all soft and sticky in summer,and hard and inelastic in the winter when it was cold.

但最初的橡胶雨衣和雨鞋在夏天都很软而且粘，而冬天当它变冷时，它又变得硬而且没有弹性。

Compared with hard-switching inverter, the soft-switching inverter's power swatches turn-on at zero voltage or zero current conditions, zero switching losses in theory, which can improve the efficiency of the system and device power density, reducing the system electromagnetic interference and ensure a brushless DC motor performance and reliability.

与硬开关逆变器相比软开关逆变器的功率开关在零电压或零电流条件下导通，理论上开关损耗为零，从而可以提高系统的效率和装置的功率密度，减小系统的电磁干扰，保证了无刷直流电机的性能和可靠性。

Indeed, the Grand Canal was constructed partly utilizing the pre-existing channels connecting these lowland swamps and lakes (3) Several rivers have produced deltaic forms on the western side of the lakes;(4) A series of artificial islands have been constructed upon the natural bars or barriers located in the lakes and wetlands, and are locally termed Duo, Dun or Wei (meaning artificial bars or crossways in Chinese).

钻孔B/M界线之下(4078 m～4530 m)的泛滥平原河湖相沉积物中局部地段富含铁锰鲕粒，其主要矿物组成为蛋白石、铁的氢氧化物(包括纤铁矿、水纤铁矿、针铁矿、水针铁矿，统称褐铁矿)、铁锰氧化物(包括硬锰矿和软锰矿，以硬锰矿为主)及极少量的细小碎屑矿物(钾长石、蚀变黑云母、含铁白云母、锆石、独居石、金红石和含钛磁铁矿)。

METHODS:Two hundred and seventy-one eyes of 219 patients with hard nucleus cataract, grading level IV or V, were operated with anteroposterior interceptive chop method for splitting the nucleus, and then with phacoemulsification. RESULTS:The hard nucleus of the 271 eyes were successfully routed. The average phaco time was 57.4 s.

对219例(271眼)级以上硬核白内障采取前后夹击劈核法，经充分水分离和水分层，吸除硬核前的皮质及软核后，乳化头退至前囊口上缘，劈核器轻压核下方，停止灌注让核上缘随前房变浅脱出囊袋口，乳化头顺势抵住核上缘，灌注加深前房后，乳化头滑入核后面，劈核器置核前面，前后夹击将核劈碎乳化吸出。

If it becomes whiter, it contains silver, if it becomes rough and hard, it contains copper and tin, if it softens and blackens it contains lead.

如果它变白了，它含有银，如果它变得粗糙和发硬，它含有铜和锡，如果它变软和发黑，它含有铅。

Even as our bones and teeth soften, the rest of our body hardens.

在我们的牙齿和骨头变软的时候，身体的其它部分却变得更硬。

With the development of highway construction, the speed of cars has been gradually increased.

随着公路的发展，汽车的车速也在不断提高。

So we basically had to develop a bond with the animal in terms of socializing with it.

所以我们就主要想通过跟它沟通的方式来建立一种良好的关系。
