Actually ,signals are processed from low frequency domain to high one by modulation firstly and alternating current amplification secondly.It can also improve anti-interference抗干扰 ability of circuit and signal to noise ratio of signals.

实际中往往采用更有效的先调制而后交流放大，将信号从低频区推移到高频区，也可以提高电路的抗干扰能力和信实际中往往采用更有效的先调制而后交流放大，将信号从低频区推移到高频区，号的信噪比。

Under the circumstance of satisfying the two necessary conditions of late-developing advantages, the potential advantage can be transformed into the motive force of development to propel the society forward and reduce the development gap between the early-developing countries. The process is a closed circle of damped oscillation. It can only turn into increasing oscillation circle with the consistent innovation and breakthrough so that the backward countries can exceed the early-developing countries.

潜在的后发优势在满足后发优势发挥作用的两个必要条件的情况下可转变为发展动力，推动社会向前发展，缩小与先发国家之间的发展差距，这一个过程是一个减幅振荡的闭路循环，只有在引进、消化的基础上不断创新、突破，才能打破单纯由后发优势导致的减幅振荡闭路循环，进入增幅振荡循环，后发国家才有可能超过先发国家。

Emphasis has been put on changes of structure properties such as crystallization, crystal cell parameter, BET surface area, average pore diameter and pore volume with addition amount of FCC decant oil under conditions that the ratios of toluene to FCC decant oil are 1∶1 and 2∶1 respectively.

结果表明，当剂油比为1∶1时，分子筛的结晶度和晶胞参数随催化油浆添加量的变化呈现先增加后减小趋势，当noil/nCTMAB=0.34时，其晶胞参数最大可以达到5.95 nm；当剂油比为2∶1时，随添加剂量的增加，分子筛结晶度降低，BET表面积成先增大后减小，而孔容和平均孔径呈逐渐增加趋势。

Before I explain my deconstruction of "news", I ought to start with recent criticisms people have made of me.

我先不如我如何解构"新闻"，我先从最近人们对我的批评说起。

There were 36 males and 40 females,with the average age of 47.7 years.36 patients presented with sciatica and perineal numbness,11 patients had painless mass and the other 20 were identified due to other causes.Among 67 benign neurogenic tumors,54 were originated from S1-S3 nerves,3 from S4-S5 nerves and 11 from the presacral space without caudal involvement.Giant cell tumor was found in 60 patients,which included 24 males and 36 females,with an average age of 32 years.Upper sacrum（S1-S2） was involved firstly.There were 56 patients（average,37.7 years） diagnosed as other primary benign bone tumors,which included 24 cases of teratomas,epidermoid cyst or dermoid cyst.Other malignant tumors,including chondrosarcoma （17）,Ewing′s sarcoma/PNET（14）,multiple myeloma（12）,lymphoma（6） and osteosarcoma（6） were found in 64 patients.

其中脊索瘤95例，男62例，女33例，平均年龄55.7岁，骶尾区疼痛是主要症状（82例），半数以上患者伴有坐骨神经痛，肿瘤多先累及低位骶骨（S3~S5）；神经源性肿瘤76例，男36例，女40例，平均年龄47.7岁，神经纤维瘤43例，神经鞘瘤24例，恶性神经鞘瘤9例，主诉多为坐骨神经痛、会阴部麻木（36例）和无痛性包块（11例），20例患者为查体或其他原因检查时发现，67例骶骨良性神经源性肿瘤起源于S3以上神经者54例，起源于S3以下神经者3例，发生于骶前未累及骶管者10例；骨巨细胞瘤60例，男24例，女36例，平均年龄32岁，腰骶尾部不适（37例）、坐骨神经痛（21例）是主要的临床表现，肿瘤多先累及上位骶骨（S1~S2）；骶骨其他原发良性肿瘤及瘤样病变56例，包括畸胎瘤、皮样囊肿、表皮样囊肿共24例；其他原发恶性肿瘤64例，包括软骨肉瘤17例，尤文肉瘤14例，多发性骨髓瘤12例，成骨肉瘤6例等。

At the start of the combat damage step, if at least one attacking or blocking creature has first strike or double strike (see rule 502.28), creatures without first strike or double strike don't assign combat damage.

在战斗伤害步骤开始时，若任一进行攻击或阻挡的生物具先攻或连击异能（见规则502.28），则不具有先攻和连击异能的生物不在此时分配战斗伤害。

For each layer-divide symbol appeares regularly in weave diagram, the layer-divide symbol is affirmed first,then the attribute of each yarn and weft is fixed,the weave of each layer is analyzed at last. As to leno fabric, the reverse side of the fabric should be analyzed, tell the crossing warp from normal warp before drafting the looming draft.This paper introduces the method to analyze this kind of complex fabric through above two examples.

对四层织物分析时，找出组织图上有代表性的组织点的属性，因分层符号在组织图上出现时很有规律，可以先确定各层分层符号的位置，进而确定各根经纬纱的属性，分出各层织物，最后分析各层的组织；纱罗织物分析时，应分析织物的反面，先要区分出绞经和地经，然后才能绘出组织图。
